Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis Of Presentation Tompkins Financial Corporation ("Tompkins" or "the Company") is registered as a Financial Holding Company with the Federal Reserve Board pursuant to the Bank Holding Company Act of 1956, as amended, organized under the laws of New York State. Tompkins is the parent company of Tompkins Community Bank, and Tompkins Insurance Agencies, Inc. ("Tompkins Insurance"). Tompkins Community Bank provides a full array of trust and investment services under the Tompkins Financial Advisors brand. Unless the context otherwise requires, the term "Company" refers to Tompkins Financial Corporation and its subsidiaries. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under GAAP. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, variable interest entities (VIEs) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when the Company has both the power and ability to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The consolidated financial statements have been prepared in accordance with GAAP. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclose contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the allowance for credit losses, valuation of goodwill and intangible assets, deferred income tax assets, and obligations related to employee benefits. The consolidated financial information included herein combines the results of operations, assets, liabilities, and shareholders’ equity (including comprehensive income or loss) of the Company and entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions are eliminated in consolidation. Amounts in the prior periods’ consolidated financial statements are reclassified when necessary to conform to the current periods’ presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure and determined that no further disclosures were required. Cash and Cash Equivalents Cash and cash equivalents in the Consolidated Statements of Cash Flows include cash and noninterest bearing balances due from banks, interest-bearing balances due from banks, Federal funds sold, and money market funds. Management regularly evaluates the credit risk associated with the counterparties to these transactions and believes that the Company is not exposed to any significant credit risk on cash and cash equivalents. Securities Management determines the appropriate classification of debt securities at the time of purchase. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity debt securities are stated at amortized cost. Debt securities not classified as held-to-maturity debt securities are classified as either available-for-sale or equity. Available-for-sale debt securities are stated at fair value with the unrealized gains and losses, net of tax, excluded from earnings and reported as a separate component of accumulated comprehensive income or loss, in shareholders’ equity. Certain equity securities that do not have a readily determinable fair value are stated at cost. Shares of stock of the Federal Home Loan Bank of New York, are also carried at cost. Premiums and discounts are amortized or accreted over the expected life or call date of the related security as an adjustment to yield using the interest method. Dividend and interest income are recognized when earned. Realized gains and losses on the sale of securities are included in net gain (loss) on securities transactions. The cost of securities sold is based on the specific identification method. For available-for-sale debt securities in an unrealized loss position, at least quarterly, the Company evaluates the securities to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit-related is recognized in other comprehensive income (loss), net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses ("ACL") on the Statements of Condition, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available-for-sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount must be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in this situation. Changes in the allowance for credit losses are recorded as provision (credit) for credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available-for-sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Accrued interest receivable on securities is excluded from the estimate of credit losses. Loans and Leases Loans are reported at their principal outstanding balance, net of deferred loan origination fees and costs, and unearned income. The Company has the ability and intent to hold its loans for the foreseeable future, except for certain residential real estate loans held-for-sale. The Company provides motor vehicle and equipment financing to its customers through direct financing leases. These leases are carried at the aggregate of lease payments receivable, plus estimated residual values, less unearned income. Unearned income on direct financing leases is amortized over the lease terms, resulting in a level rate of return. Residential real estate loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Fair value is determined on the basis of the rates quoted in the secondary market. Net unrealized losses attributable to changes in market interest rates are recognized through a valuation allowance by charges to income. Loans are generally sold on a non-recourse basis with servicing retained. Any gain or loss on the sale of loans is recognized at the time of sale as the difference between the recorded basis in the loan and the net proceeds from the sale. The Company may use commitments at the time loans are originated or identified for sale to mitigate interest rate risk. The commitments to sell loans and the commitments to originate loans held-for-sale at a set interest rate, if originated, are considered derivatives under Accounting Standard Codification ("ASC") Topic 815, Derivatives and Hedging . The impact of the estimated fair value adjustment was not significant to the consolidated financial statements. Interest income on loans is accrued and credited to income based upon the principal amount outstanding. Loan origination fees and costs are deferred and recognized over the life of the loan as an adjustment to yield. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments are due. Loans and leases, including individually evaluated loans, are generally classified as nonaccrual if they are past due as to maturity or payment of principal or interest for a period of more than 90 days, unless such loans are well secured and in the process of collection. Loans that are past due less than 90 days may also be classified as nonaccrual if repayment in full of principal or interest is in doubt. Loans may be returned to accrual status when all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within an acceptable time period, and there is a sustained period (generally six consecutive months) of repayment performance by the borrower in accordance with the contractual terms of the loan agreement. When interest accrual is discontinued, all unpaid accrued interest is reversed. Payments received on loans on nonaccrual are generally applied to reduce the principal balance of the loan. In general, the principal balance of a loan is charged off in full or in part when management concludes, based on the available facts and circumstances, that collection of principal in full is not probable. For commercial and commercial real estate loans, this conclusion is generally based upon a review of the borrower’s financial condition and cash flow, payment history, economic conditions, and the conditions in the various markets in which the collateral, if any, may be liquidated. In general, consumer loans are charged-off in accordance with regulatory guidelines which provide that such loans be charged-off when the Company becomes aware of the loss, such as from a triggering event that may include new information about a borrower’s intent/ability to repay the loan, bankruptcy, fraud or death, among other things, but in no case will the charge-off exceed specified delinquency timeframes. Such delinquency timeframes state that closed-end retail loans (loans with pre-defined maturity dates, such as real estate mortgages, home equity loans and consumer installment loans) that become past due 120 cumulative days and open-end retail loans (loans that roll-over at the end of each term, such as home equity lines of credit) that become past due 180 cumulative days should be classified as a loss and charged-off. For residential real estate loans, charge-off decisions are based upon past due status, current assessment of collateral value, and general market conditions in the areas where the properties are located. Acquired Loans Acquired loans are recorded at fair value at the date of acquisition based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Certain larger purchased loans are individually evaluated while other purchased loans are grouped together according to similar risk characteristics and are treated in the aggregate when applying various valuation techniques. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. Allowance for Credit Losses – Loans The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis. Expected credit losses are reflected in the ACL through a charge to the provision for credit loss expense. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the ACL is reduced by the same amount. In general, the principal balance of a loan is charged off in full or in part when management concludes, based on the available facts and circumstances, that collection of principal in full is not probable. In addition, the Company has reserves for expected recoveries where the Company reviews the prior four quarter charge-offs and applies a recovery rate based on the Company’s historical experience. Subsequent recoveries, if any, are credited to the ACL when received. The Company measures expected credit losses of financial assets at the loan level by segment, by pooling loans when the financial assets share similar risk characteristics. Depending on the nature of the pool of financial assets with similar risk characteristics, the Company uses a discounted cash flow ("DCF") method to estimate the expected credit losses. Allowance on loans that do not share risk characteristics are evaluated on an individual basis. The Company assigns a credit risk rating to all commercial and commercial real estate loans. The Company reviews commercial and commercial real estate loans rated Substandard or worse, on nonaccrual, and greater than $250,000 for loss potential and when deemed appropriate, assigns an allowance based on an individual evaluation. The Company’s methodologies for estimating the ACL consider available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The methodologies apply historical loss information, adjusted for asset-specific characteristics, economic conditions at the measurement date, and forecasts about future economic conditions expected to exist through the contractual lives of the financial assets that are reasonable and supportable, to the identified pools of financial assets with similar risk characteristics for which the historical loss experience was observed. The Company’s methodologies revert back to average historical loss information on a straight line basis over eight quarters when it can no longer develop reasonable and supportable forecasts. The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: commercial, commercial real estate, residential, home equity, consumer and leases. This segmentation was selected based on the differences in the risk profile of each of these categories and aligns well with regulatory reporting categories. This segmentation separates borrower type, collateral type and the nature of the loan. The differences in risk profiles of these segments enable the ACL to be more precise in its allocation due to the inherent risk in these specific portfolios. Discounted Cash Flow Method The Company uses the DCF method to estimate expected credit losses for the commercial, commercial real estate, residential, home equity, and consumer loan pools. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for exposure at default using estimated prepayment speeds, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, and time to recovery are based on historical internal data. The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loan pools utilizing the DCF method, management utilizes and forecasts national unemployment and a one-year percentage change in national gross domestic product as loss drivers in the model. For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over eight quarters on a straight-line basis. Management leverages economic projections from an independent third party to inform its loss driver forecasts over the four-quarter forecast period. Other internal and external indicators of economic forecasts, and scenario weightings, are also considered by management when developing the forecast metrics. The model considers a base case forecast and two alternative forecasts and assigns weightings to these three scenarios based on current conditions and expectations for future conditions. The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows ("NPV"). An ACL is established for the difference between the instrument’s NPV and amortized cost basis. The model also considers the need to qualitatively adjust expected loss estimates for information not already captured in the loss estimation process. These qualitative factors include, but are not limited to, those suggested by the Interagency Policy Statement on Allowances for Credit Losses. These qualitative factor adjustments may increase or decrease the Company's estimate of expected credit losses. Due to the size and characteristics of the leasing portfolio, the remaining life method, using the historical loss rate of the commercial and industrial segment, is used to determine the allowance for credit losses. Individually Evaluated Financial Assets Loans that do not share common risk characteristics are evaluated on an individual basis. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral less cost to sell, and the amortized cost basis of the asset as of the measurement date. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. For acquired credit impaired loans accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, ("ASC Topic 310-30"), the Company’s allowance for loan and lease losses was estimated based upon our expected cash flows for these loans. To the extent that we experienced a deterioration in borrower credit quality resulting in a decrease in our expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on our estimate of future credit losses over the remaining life of the loans. For acquired non-credit impaired loans accounted for under FASB ASC Topic 310-20, Nonrefundable Fees and Other Costs, ("ASC Topic 310-20"), the Company’s allowance for loan and lease losses was maintained through provisions for loan losses based upon an evaluation process that was similar to our evaluation process used for originated loans. In conducting this evaluation, which included a review of loans on which full collectability may not be reasonably assured, the Company considered, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan loss experience, carrying value of the loans, which included the remaining net purchase discount or premium, and other factors that warrant recognition in determining our allowance for loan losses. The Company adopted Accounting Standard Update ("ASU") 2016-13 on January 1, 2020, using the prospective transition approach for financial assets purchased with credit deterioration ("PCD") that were previously classified as purchased credit impaired ("PCI") and accounted for under ASC 310-30. In accordance with the standard, the Company did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The remaining discount on the PCD assets will be accreted into interest income on a level-yield method over the life of the loans. Loan Modifications The Company adopted ASU 2022-02 effective January 1, 2023. This standard eliminated the previous troubled debt restructuring ("TDR") accounting model and replaced it with guidance and disclosure requirements for identifying modifications to loans to borrowers experiencing financial difficulty. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearances, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, unused lines of credit and commercial letters of credit, issued to meet customer financing needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancellable, through a charge to the provision for credit loss expense for off-balance sheet credit exposures included in other noninterest expense in the Company’s Consolidated Statements of Income. The ACL on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using similar methodologies as portfolio loans, taking into consideration the likelihood that funding will occur, and is included in other liabilities on the Company’s Statements of Condition. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, less allowances for depreciation. The provision for depreciation for financial reporting purposes is computed generally by the straight-line method at rates sufficient to write-off the cost of such assets over their estimated useful lives. Buildings are amortized over a period of 10-39 years, and furniture, fixtures, and equipment are amortized over a period of 2-20 years. Leasehold improvements are generally depreciated over the lesser of the lease term or the estimated lives of the improvements. Maintenance and repairs are charged to expense as incurred. Gains or losses on disposition are reflected in earnings. Leases The Company leases certain office facilities and office equipment under operating leases. The Company also owns certain office facilities which it leases to outside parties under operating lessor leases; however, such leases are not significant. For operating leases other than those considered to be short-term, defined as leases of 12 months or less, the Company recognizes operating lease right-of-use ("ROU") assets and related lease liabilities at the time of lease commencement. ROU assets represent the Company's right to use the underlying asset for the lease term and the lease liabilities represent the Company's obligation to make lease payments under the leases. ROU assets and operating lease liabilities are reported as components of accrued interest and other assets and other liabilities, respectively, on our accompanying consolidated balance sheets. Leases with terms of 12 months or less are recognized in the income statement over the lease term. In recognizing ROU assets and related lease liabilities, the Company accounts for lease and non-lease components (such as taxes, insurance, and common area maintenance costs) separately as such amounts are generally readily determinable under our lease contracts. To estimate the present value of lease payments over the expected lease term, the Company uses interest rates on advances from the FHLB at the time of commencement. The Company's lease term may include options to extend or terminate the leases when it is reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term and is included in net occupancy expense of premises in the Company's Consolidated Statements of Income. Bank Owned Life Insurance The Company owns life insurance policies on certain current and former employees and directors where the Bank is the beneficiary. Bank owned life insurance ("BOLI") is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value (“CSV”) adjusted for other charges or other amounts due that are probable at settlement. Increases in the CSV of the policies, as well as the death benefits received, net of any CSV, are recorded in noninterest income, and are not subject to income taxes. Other Real Estate Owned Other real estate owned consists of properties formerly pledged as collateral to loans, which have been acquired by the Company through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Upon transfer of a loan to foreclosure status, an appraisal is generally obtained and any excess of the loan balance over the fair value, less estimated costs to sell, is charged against the allowance for credit losses. Expenses and subsequent adjustments to the fair value are treated as other operating expense. Goodwill Goodwill represents the excess of purchase price over the fair value of assets acquired in a transaction using purchase accounting. Goodwill has an indefinite useful life and is not amortized, but is tested for impairment. Goodwill impairment tests are performed on an annual basis or when events or circumstances dictate. On January 1, 2020, the Company adopted ASU 2017-04 , "Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment", which eliminates an entity's requirement to compute the implied fair value. The Company tests goodwill annually as of December 31 st . The Company has the option to perform a qualitative assessment of goodwill, which considers company-specific and economic characteristics that might impact its carrying value. If, based on this qualitative assessment, it is more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative test (Step 1) is performed, which compares the fair value of the reporting unit to the carrying amount of the reporting unit in order to identify potential impairment. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not considered impaired. The implied fair value of goodwill is determined in the same manner as goodwill that is recognized in a business combination. Significant judgment and estimates are involved in estimating the fair value of the assets and liabilities of the reporting units. Other Intangible Assets Other intangible assets include core deposit intangibles, customer related intangibles, covenants not to compete, and mortgage servicing rights. Core deposit intangibles represent a premium paid to acquire a base of stable, low cost deposits in the acquisition of a bank, or a bank branch, using purchase accounting. The amortization period for core deposit intangible ranges from 5 to 10 years, using an accelerated method. The covenants not to compete are amortized on a straight-line basis over 3 to 6 years, while customer related intangibles are amortized on an accelerated basis over a range of 6 to 15 years. The amortization period is monitored to determine if circumstances require such periods to be revised. The Company periodically reviews its intangible assets for changes in circumstances that may indicate the carrying amount of the asset is impaired. The Company tests its intangible assets for impairment on an annual basis or more frequently if conditions indicate that an impairment loss has more likely than not been incurred. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are reviewed quarterly and reduced by a valuation allowance if, based upon the information available, it is more likely than not that some or all of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. In such cases, although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense in the Consolidated Statements of Income. Tax Credit Investments The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method. Under that method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase (repurchase agreements) are agreements in which the Company transfers the underlying securities to a third-party custodian’s account that explicitly recognizes the Company’s interest in the securities. The agreements are accounted for as secured financing transactions provided the Company maintains effective control over the transferred securities and meets other criteria as specified in FASB ASC Topic 860, Transfers and Servicing ("ASC Topic 860"). The Company’s agreements are accounted for as secured financings; accordingly, the transaction proceeds are reflected as liabilities and the securities underlying the agreements continue to be carried in the Company’s securities portfolio. Treasury Stock The cost of treasury stock is shown on the Consolidated Statements of Condition as a separate component of shareholders’ equity, and is a reduction to total shareholders’ equity. Shares are released from treasury at fair value, identified on an average cost basis. Trust and Investment Services Assets held in fiduciary or agency capacities for customers are not included in the accompanying Consolidated Statements of Condition, since such items are not assets of the Company. Fees associated with providing trust and investment services are included in noninterest income. Additional information on trust and investment fees is presented in "Note 13 - Revenue Recognition."

The Company did not recognize any gains on called securities for the years ended December 31, 2024, 2023 and 2022. The Company also recognized net losses of $18,400, net gains of $10,000, and net losses of $125,000 on equity securities for the years ended December 31, 2024, 2023 and 2022, respectively, reflecting the change in fair value. In 2023, the Company completed a balance sheet repositioning for general balance sheet, portfolio and interest rate risk management, by selling approximately $510.5 million of available-for-sale debt securities, which resulted in an pre-tax loss on the sale of approximately $70.0 million. In the fourth quarter of 2022, the Company sold its Class B common shares of Visa Inc. for $11.4 million. The shares had no carrying value on the Company's Consolidated Statements of Condition, and the Company had no historical cost basis in the shares, thus the $11.4 million was realized as a pre-tax gain. The Company received the shares as part of its membership interest in Visa in March 2008.

Factors that may be indicative of ECL include, but are not limited to, the following: • Extent to which the fair value is less than the amortized cost basis. • Adverse conditions specifically related to the security, an industry, or geographic area (changes in technology, business practice). • Payment structure of the debt security with respect to underlying issuer or obligor. • Failure of the issuer to make scheduled payment of principal and/or interest. • Changes to the rating of a security or issuer by a nationally recognized statistical rating organization. • Changes in tax or regulatory guidelines that impact a security or underlying issuer. For available-for-sale debt securities in an unrealized loss position, the Company evaluates the securities to determine whether the decline in the fair value below the amortized cost basis is the result of changes in interest rates or reflects a fundamental change in the credit worthiness of the underlying issuer. Any impairment that is not credit related is recognized in other comprehensive income (loss), net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses ("ACL") on the Statements of Condition, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the ACL and the adjustment to net income may be reversed if conditions change. Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management has made the accounting policy election to exclude accrued interest receivable on held-to-maturity debt securities from the estimate of credit losses. As of December 31, 2024, the held-to-maturity portfolio consisted of U.S. Treasury securities and securities issued by U.S. government-sponsored enterprises, including the Federal National Mortgage Agency and the Federal Farm Credit Banks Funding Corporation. U.S. Treasury securities are backed by the full faith and credit of and/or guaranteed by the U.S. government, and it is expected that the securities will not be settled at prices less than the amortized cost bases of the securities. Securities issued by U.S. government agencies or U.S. government-sponsored enterprises carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as "risk-free," and have a long history of zero credit loss. As such, the Company did not record an allowance for credit losses for these securities as of December 31, 2024. The total gross unrealized losses, shown in the tables above, were primarily attributable to changes in interest rates and levels of market liquidity, relative to when the investment securities were purchased, and not due to the credit-related quality of the investment securities. The Company does not have the intent to sell these securities and does not believe it is more likely than not that the Company will be required to sell these securities before a recovery of amortized cost. The gross unrealized losses reported for available-for-sale residential mortgage-backed securities relate to investment securities issued by U.S. government sponsored entities such as Federal National Mortgage Association, FHLMC and U.S. government agencies such as Government National Mortgage Association. The gross unrealized losses for held-to-maturity debt securities are on US Treasuries and securities issued by U.S. government-sponsored enterprises, including the Federal National Mortgage Agency and the Federal Farm Credit Banks Funding Corporation. The Company did not recognize any net credit impairment charge to earnings on investment securities in 2024, 2023, or 2022. The amortized cost and estimated fair value of debt securities by contractual maturity are shown in the following table. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Mortgage-backed securities are shown separately since they are not due at a single maturity date.

Pledged Securities The Company pledges securities as collateral for public deposits and other borrowings, and sells securities under agreements to repurchase. See "Note 8 - Federal Funds Purchased and Securities Sold Under Agreements to Repurchase" for further discussion. Securities carried of $904.2 million and $1.0 billion, at December 31, 2024 and 2023, respectively, were either pledged or sold under agreements to repurchase. Concentrations of Securities Except for U.S. government securities, there were no holdings, when taken in the aggregate, of any single issuer that exceeded 10% of shareholders’ equity at December 31, 2024. Equity Securities The Company invests in one equity fund. This security is carried at fair value. Investment in Small Business Investment Companies The Company has equity investments in small business investment companies ("SBIC") established for the purpose of providing financing to small businesses in market areas served by the Company. These investments totaled $671,000 and $485,000 at December 31, 2024 and 2023, respectively, and were included in other assets on the Company’s Consolidated Statements of Condition. These investments are accounted for either under the cost method or the equity method of accounting. As of December 31, 2024, the Company reviewed these investments and determined that there was no impairment. Federal Home Loan Bank Stock The Company also holds non-marketable Federal Home Loan Bank New York ("FHLBNY") stock and non-marketable Atlantic Community Bankers Bank ("ACBB") stock, all of which are required to be held for regulatory purposes and for borrowing availability. The required investment in FHLB stock is tied to the Company’s borrowing levels with the FHLB. Holdings of FHLBNY stock and ACBB stock totaled $42.2 million and $95,000 at December 31, 2024, respectively. These securities are carried at par, which is also cost. As of December 31, 2024, the FHLBNY continued to pay dividends and repurchase stock. As such, the Company has not recognized any impairment on its holdings of FHLBNY.

The Company has adopted comprehensive lending policies, underwriting standards and loan review procedures. There were no significant changes to the Company’s existing lending policies, underwriting standards or loan review procedures during 2024. The Company’s Board of Directors approves the lending policies at least annually. The Company recognizes that exceptions to policy guidelines may occasionally occur and has established procedures for approving exceptions to these policy guidelines. Management has also implemented reporting systems to monitor loan originations, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans. Residential real estate loans The Company’s policy is to underwrite residential real estate loans in accordance with secondary market guidelines in effect at the time of origination, including loan-to-value ("LTV") and documentation requirements. LTVs exceeding 80% for fixed rate loans and 80% for adjustable rate loans require private mortgage insurance to reduce the exposure. The Company verifies applicants’ income, obtains credit reports and independent real estate appraisals in the underwriting process to ensure adequate collateral coverage and that loans are extended to individuals with good credit and income sufficient to repay the loan. In limited circumstances, the Company will make exceptions to secondary market underwriting standards to support community reinvestment activities. The Company originates fixed rate and adjustable rate residential mortgage loans, including loans that have characteristics of both, such as a 7/6 adjustable rate mortgage, which has a fixed rate for the first seven years and then adjusts semi-annually thereafter. The majority of residential mortgage loans originated over the last several years have been fixed rate loans. Adjustable rate loans have increased in popularity due to the rising interest rate environment. Adjustable rate residential real estate loans are underwritten based upon the initial rate when the fixed rate period is 5 years or longer. For loans with an initial fixed rate of less than 5 years, the fully indexed rate is utilized for the ability to repay qualifying and underwriting. This underwriting practice matches secondary market guidelines. The Company may sell residential real estate loans in the secondary market based on interest rate considerations. These residential real estate loans are generally sold to FHLMC or SONYMA without recourse in accordance with standard secondary market loan sale agreements. These residential real estate loan sales are subject to customary representations and warranties, including representations and warranties related to gross incompetence and fraud. The Company has not had to repurchase any loans as a result of these general representations and warranties. During 2024, 2023, and 2022, the Company sold residential mortgage loans totaling $40.1 million, $4.5 million, and $8.9 million, respectively, and realized net gains on these sales of $1.0 million, $96,000, and $155,000, respectively. These residential real estate loans are generally sold without recourse in accordance with standard secondary market loan sale agreements. When residential mortgage loans are sold to FHLMC or SONYMA, the Company typically retains all servicing rights, which provides the Company with a source of fee income. In connection with the sales in 2024, 2023, and 2022, the Company recorded mortgage-servicing assets of $299,000, $34,000, and $66,000, respectively. The loans sold to FHLMC and SONYMA were originated with the intent to sell. Amortization of mortgage servicing assets amounted to $91,000 in 2024, $81,000 in 2023, and $128,000 in 2022. At December 31, 2024 and 2023, the Company serviced residential mortgage loans aggregating $158.0 million and $130.4 million. Mortgage servicing rights, at an amortized cost basis, totaled $1.1 million at December 31, 2024 and $927,000 at December 31, 2023. These mortgage servicing rights were evaluated for impairment at year-end 2024 and 2023 and no impairment was recognized. Loans held for sale, which are included in residential real estate, totaled $1.7 million and $602,000 at December 31, 2024 and 2023, respectively. As members of the FHLB, the Company’s subsidiary bank may use unencumbered mortgage related assets to secure borrowings from the FHLB. At December 31, 2024 and 2023, the Company had $543.2 million and $125.0 million, respectively, of term advances from the FHLB that were secured by residential mortgage loans. In addition to the term advances presented above, standby letters of credit with the FHLB of $200 million and $316 million, at December 31, 2024 and 2023, respectively, were secured by residential mortgage loans. Commercial and industrial loans The Company’s Commercial Loan Policy sets forth guidelines for debt service coverage ratios, LTV’s and documentation standards. Commercial and industrial loans are primarily made based on identified cash flows of the borrower with consideration given to underlying collateral and personal or government guarantees. The Company’s policy establishes debt service coverage ratio limits that require a borrower’s cash flow to be sufficient to cover principal and interest payments on all new and existing debt. Commercial and industrial loans are generally secured by the assets being financed or other business assets such as accounts receivable or inventory. Many of the loans in the commercial portfolio have variable interest rates tied to Prime Rate, FHLBNY borrowing rates, Secured Overnight Financing Rate ("SOFR"), or U.S. Treasury indices. Commercial real estate The Company’s Commercial Loan Policy sets forth guidelines for debt service coverage ratios, LTV’s and documentation standards. Commercial real estate loans are primarily made based on identified cash flows of the borrower with consideration given to underlying real estate collateral and personal or government guarantees. The Company’s policy establishes a maximum LTV based on the type of property and debt service coverage ratio limits that require a borrower’s cash flow to be sufficient to cover principal and interest payments on all new and existing debt. Commercial real estate loans may be fixed or variable rate loans with interest rates tied to Prime Rate, FHLBNY borrowing rates, SOFR, or U.S. Treasury indices. Agriculture loans Agriculturally-related loans include loans to dairy farms, cash and vegetable crop farms and a variety of other livestock and crop producers. Agriculturally-related loans are primarily made based on identified cash flows of the borrower with consideration given to underlying collateral, personal guarantees, and government related guarantees. Agriculturally-related loans are generally secured by the assets or property being financed or other business assets such as accounts receivable, livestock, equipment, or commodities/crops. The Company’s policy establishes a maximum LTV based on the type of property and debt service coverage ratio limits that require a borrower’s cash flow to be sufficient to cover principal and interest payments on all new and existing debt, with limited adjustments to consider commodity market cycles. The policy also establishes maximum LTV ratios for non-real estate collateral, such as livestock, commodities/crops, equipment and accounts receivable. Agriculturally-related loans may be fixed or variable rate with interest tied to Prime Rate, FHLBNY borrowing rates, SOFR, or U.S. Treasury indices. Consumer and other loans The consumer loan portfolio includes indirect and direct loans relating to personal installment loans, automobile financing, and overdraft lines of credit. The majority of the consumer portfolio consists of indirect and direct automobile loans. Consumer loans are generally short-term and have fixed rates of interest that are set giving consideration to current market interest rates, the financial strength of the borrower, and internal profitability targets. The Company's Consumer Loan Underwriting Guidelines Policy establishes maximum debt to income ratios and includes guidelines for verification of applicants’ income and receipt of credit reports. Leases Leases are primarily made to commercial customers and the origination criteria typically includes the value of the underlying assets being financed, the useful life of the assets being financed, and identified cash flows of the borrower. Most leases carry a fixed rate of interest that is set giving consideration to current market interest rates, the financial strength of the borrower, and internal profitability targets. Loan and Lease Customers The Company’s loan and lease customers are located primarily in the upstate New York and Pennsylvania communities served by Tompkins Community Bank. The Bank operates twelve banking offices in the counties of Tompkins, Cayuga, Cortland, Onondaga and Schuyler, New York; fourteen banking offices in the counties of Wyoming, Livingston, Genesee, Orleans and Monroe, New York; twelve banking offices in the counties of Putnam County, Dutchess County and Westchester, New York; and sixteen offices in the counties of Berks, Montgomery, Philadelphia, Delaware and Schuylkill, Pennsylvania. Other than general economic risks, management is not aware of any material concentrations of credit risk to any industry or individual borrower. Loans to Related Parties Directors and officers of the Company and its affiliated companies are customers of, and have other transactions with, the Company's banking subsidiaries in the ordinary course of business. Such loans and commitments are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons not related to the Company, and did not involve more than normal risk of collectability or present other unfavorable features. Nonaccrual Loans and Leases Loans are considered past due if the required principal and interest payments have not been received as of the date such payments are due. Loans are placed on nonaccrual status either due to the delinquency status of principal and/or interest (generally when past due 90 or more days) or a judgment by management that the full repayment of principal and interest is unlikely. When interest accrual is discontinued, all unpaid accrued interest is reversed. Payments received on loans on nonaccrual are generally applied to reduce the principal balance of the loan. Loans are generally returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. When management determines that the collection of principal in full is improbable, management will charge-off a partial amount or full amount of the loan balance. Management considers specific facts and circumstances relative to each individual credit in making such a determination. For residential and consumer loans, management uses specific regulatory guidance and thresholds for determining charge-offs.

Allowance for Credit Losses

Allowance for Credit Losses	12 Months Ended
	Dec. 31, 2024
Receivables [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses Management reviews the appropriateness of the ACL on a regular basis. Management considers the accounting policy relating to the allowance to be a critical accounting policy, given the inherent uncertainty in evaluating the levels of the allowance required to cover credit losses in the portfolio and the material effect that assumptions could have on the Company’s results of operations. The Company has developed a methodology to measure the amount of estimated credit loss exposure inherent in the loan portfolio to assure that an appropriate allowance is maintained. The Company’s methodology is based upon guidance provided in SEC Staff Accounting Bulletin No. 119, Measurement of Credit Losses on Financial Instruments ("CECL"), and Financial Instruments - Credit Losses and ASC Topic 326, Financial Instruments - Credit Losses. The Company uses a DCF method to estimate expected credit losses for all loan segments excluding the leasing segment. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, recovery lag, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on internal historical data. The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loans utilizing the DCF method, management utilizes forecasts of national unemployment rates and a one year percentage change in national gross domestic product as loss drivers in the model. For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over eight quarters on a straight-line basis. Management leverages economic projections from a reputable and independent third party to inform its loss driver forecasts over the four-quarter forecast period. Other internal and external indicators of economic forecasts, and scenario weightings, are also considered by management when developing the forecast metrics. Due to the size and characteristics of the leasing portfolio, the Company uses the remaining life method, using the historical loss rate of the commercial and industrial segment, to determine the allowance for credit losses. The combination of adjustments for credit expectations and timing expectations produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce a net present value of expected cash flows ("NPV"). An ACL is established for the difference between the NPV and amortized cost basis. Since the methodology is based upon historical experience and trends, current conditions, and reasonable and supportable forecasts, as well as management’s judgment, factors may arise that result in different estimates. While management’s evaluation of the allowance as of December 31, 2024 considers the allowance to be appropriate, under adversely different conditions or assumptions, the Company would need to increase or decrease the allowance. In addition, various federal and State regulatory agencies, as part of their examination process, review the Company's allowance and may require the Company to recognize additions to the allowance based on their judgments and information available to them at the time of their examinations. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, and commercial letters of credit. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancellable, through a charge to credit loss expense for off-balance sheet credit exposures included in provision expense in the Company's consolidated statements of income.

Employee Benefit Plans

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company maintains a noncontributory defined-benefit plan (the "DB Pension Plan") and a 401(k) plan (the "Retirement Savings Plan"). The Company makes both matching contributions and discretionary contributions under the Retirement Savings Plan, which covers substantially all employees of the Company. The DB Pension Plan was closed to new employees at year-end 2009 and was frozen on July 31, 2015. The benefits under the DB Pension Plan are based on years of service, age and percentages of the employees' average final compensation. The Retirement Savings Plan offers the participant a wide range of investment alternatives from which to choose. Assets of the Company's DB Pension Plan are invested in mutual funds and cash equivalents. The Retirement Savings Plan covers substantially all employees of the Company who have reached the age of 21. The Company makes matching contributions to an account set up in the participant's name. Employees may contribute a percentage of their eligible compensation with a Company match of such contributions up to a maximum match of 2%. The Company also provided an additional employer contribution of 2% of the employee's base pay. The Company’s expense associated with these contributions was $3.4 million in 2024, $3.2 million in 2023, and $3.1 million in 2022. In addition, discretionary contributions are made once per year and equals a percentage of pay and varies based on the participant's age, service, and tenure with the Company. Expenses related to the discretionary contributions totaled $3.9 million in 2024, $4.2 million in 2023, and $4.1 million in 2022. The Company has an Employee Stock Ownership Plan ("ESOP") covering substantially all employees of the Company that have at least one year of service. The ESOP allows for Company contributions in the form of common stock of the Company. Annually, the Tompkins Board of Directors determines a profit-sharing payout to its employees in accordance with a performance-based formula. A percentage of the approved amount is paid in Company common stock into the ESOP. Contributions are limited to a maximum amount as stipulated in the ESOP. The remaining percentage is either paid out in cash, contributed to a health savings account, or deferred into the Retirement Savings Plan at the direction of the employee. Compensation expense related to the profit-sharing payout totaled $3.8 million in 2024, $1.4 million in 2023, and $5.3 million in 2022. The Company maintains supplemental employee retirement plans ("SERPs") for certain executives. In 2016, certain SERPs were amended and restated to reflect changes resulting from the freezing of the DB Pension Plan, and the Company entered into additional SERP agreements with certain executives. In 2019, the SERP for the Company's CEO was amended to expand the definition of "Earnings" under the SERP to better align the scope of compensation included in our CEO's retirement benefits with chief executive compensation in a manner that is more consistent with market practice. All benefits provided under the SERPs are unfunded and the Company makes payments to plan participants. The Company also maintains a post-retirement welfare benefit plan that provides health and death benefits for certain team members. Under this plan, as amended in 2005, the Company contributes toward post-retirement healthcare benefits for employees who commenced employment prior to January 1, 2005. Retirees and employees who were eligible to retire when the health benefit was amended were unaffected. Generally, all other employees were eligible for Health Reimbursement Accounts ("HRA") with an initial balance equal to the amount of the Company’s estimated then current liability. Contributions to the plan are limited to an annual contribution of 4% of the total HRA balance. Employees, upon retirement, will be able to utilize their HRA for qualified health costs and deductibles. In 2019, the death benefit was discontinued for new entrants, and only employees who had attained age 50 as of February 1, 2020 are eligible to earn this benefit. The Company engages independent, external actuaries to compute the amounts of liabilities and expenses relating to all of its employee benefits plans, subject to the assumptions that the Company selects. The benefit obligation for these plans represents the liability of the Company for current and former employees, and is affected primarily by the following: service cost (benefits attributed to employee service during the period); interest cost (interest on the liability due to the passage of time); actuarial gains/losses (experience during the year different from that assumed and changes in plan assumptions); and benefits paid to participants. GAAP requires an employer to recognize in its statements of condition as an asset or liability the overfunded or underfunded status of a defined benefit postretirement plan, measured as the difference between the fair value of plan assets and the benefit obligation. For a pension plan, the benefit obligation is the projected benefit obligation; for any other postretirement benefit plan, such as a retiree health care plan, the benefit obligation is the accumulated postretirement benefit obligation. The following table sets forth the changes in the projected benefit obligation for the DB Pension Plan and SERPs and the accumulated post-retirement benefit obligation for the Life and Healthcare Plan, the respective plan assets, and the plans’ funded status and amounts recognized in the Company’s Consolidated Statements of Condition at December 31, 2024 and 2023 (the measurement dates of the plans).

The accumulated benefit obligation for the SERPs at December 31, 2024 was $20.0 million and was $21.1 million at December 31, 2023. The funded status of the DB Pension Plan was recognized in accrued interest and other assets, and the unfunded status of the Life and Healthcare Plan and the SERPs was recognized in other liabilities in the Consolidated Statements of Condition at December 31, 2024 in the amounts of $23.1 million, $(6.9) million, and $(22.9) million, respectively.

Based on this analysis, the Company selected 6.25% as the long-term rate of return on assets assumption. The discount rates used to determine the Company’s DB Pension Plan and other post-retirement benefit obligations as of December 31, 2024, and December 31, 2023, were determined by matching estimated benefit cash flows to a yield curve derived from Citigroup’s regular bond yield at December 31, 2024 and December 31, 2023. Based on the Company’s anticipation of future experience under the DB Pension Plan, the mortality tables used to determine future benefit obligations under the plan were updated as of December 31, 2021 to the PRI-2012 Mortality Tables with Mortality Improvement Scale MP 2021. The Company updated this assumption based on the newest improvement table released by The Society of Actuaries as of December 31, 2024. The appropriateness of the assumptions is reviewed annually. Cash Flows Plan assets are amounts that have been segregated and restricted to provide benefits, and include amounts contributed by the Company and amounts earned from investing contributions, less benefits paid. The Company funds the cost of the SERPs and the Life and Healthcare Plan benefits on a pay-as-you-go basis. The benefits as of December 31, 2024, expected to be paid in each of the next five fiscal years, and in the aggregate for the five fiscal years thereafter were as follows: (In thousands) DB Pension Plan Life and Healthcare Plan SERP Plan 2025 $ 4,446 $ 486 $ 958 2026 4,620 487 948 2027 4,772 500 925 2028 4,744 493 900 2029 4,865 478 1,069 2029-2033 24,569 2,256 9,706 Total $ 48,016 $ 4,700 $ 14,506 Plan Assets The DB Pension Plan’s weighted-average asset allocations at December 31, 2024 and 2023, respectively, by asset category are as follows: 2024 2023 Equity securities 60 % 61 % Debt securities 39 % 38 % Other 1 % 1 % Total Allocation 100 % 100 % It is the policy of the Trustees of the Plan to invest the Pension Trust Fund (the "Fund") for total return. The Trustees seek the maximum return consistent with the interests of the participants and beneficiaries and prudent investment management. The management of the Fund’s assets is in compliance with the guidelines established in the Company’s Pension Plan and Trust Investment Policy, which is reviewed and approved annually by the Tompkins Board of Directors, and the Retirement Plan Management Committee. The intention is for the Fund to be prudently diversified. The Fund’s investments will be invested among the fixed income, equity and cash equivalent sectors. The Retirement Plan Management Committee will designate minimum and maximum positions in any of the sectors. In no case shall more than 10% of the Fund assets consist of qualified securities or real estate of the Company. Unless otherwise approved by the Trustees of the Plan, the following investments are prohibited: • Restricted stock, private placements, short positions, calls, puts, or margin transactions; • Commodities, oil and gas properties, real estate properties, or • Any investment that would constitute a prohibited transaction as described in the Employee Retirement Income Security Act of 1974 ("ERISA"), section 407, 29 U.S.C. 1106. In general, the investment in debt securities is limited to readily marketable debt securities having a Standard & Poor’s rating of "A" or Moody’s rating of "A", securities of, or guaranteed by the United States Government or its agencies, or obligations of banks or their holding companies that are rated in the three highest ratings assigned by Fitch Investor Service, Inc. In addition, investments in equity securities must be listed on the NYSE or traded on the national Over-the-Counter market or listed on the NASDAQ. Cash equivalents generally may be United States Treasury obligations, commercial paper having a Standard & Poor’s rating of "A-1" or Moody’s National Credit Officer rating of "P-1"or higher. The major categories of assets in the Company’s DB Pension Plan as of year-end are presented in the following table.

The pricing service uses a variety of techniques to determine fair value, including market maker bids, quotes and pricing models. Inputs to the model include recent trades, benchmark interest rates, spreads, and actual and projected cash flows. Based on the inputs used by our independent pricing services, the Company identifies the appropriate level within the fair value hierarchy to report these fair values. U.S. Treasury securities, common stocks and mutual funds are considered Level 1 based on quoted prices in active markets. Life insurance benefits are provided to certain officers of the Company. In connection with these policies, the Company reflected life insurance assets on its Consolidated Statements of Condition of $76.4 million at December 31, 2024, and $67.9 million at December 31, 2023. The insurance is carried at its cash surrender value on the Consolidated Statements of Condition. The Company purchased $6.3 million of insurance in 2024. In the fourth quarter of 2023, the Company surrendered certain separate account BOLI policies. Increases in the cash surrender value of the insurance are reflected as noninterest income, net of any related mortality expense. The Company provides split dollar life insurance benefits to certain employees. The plan is unfunded and the estimated liability of the plan is recorded in other liabilities in the Consolidated Statements of Condition at $1.7 million as of December 31, 2024 and $1.5 million as of December 31, 2023. Compensation expense related to the split dollar life insurance was approximately $177,000 in 2024 and $3,000 in 2023.

Stock Plans and Stock Based Compensation	Stock Plans and Stock-Based Compensation In 2019, the 2009 Tompkins Financial Corporation Equity Plan ("2009 Equity Plan") expired and was replaced by the new Tompkins Financial Corporation 2019 Equity Plan ("2019 Equity Plan"). Under the 2019 Equity Plan, the Company may grant stock options, stock appreciation rights ("SARs"), shares of restricted stock, restricted units and performance share awards covering up to 2,275,000 shares of the Company's common stock to certain officers and employees. Restricted stock awards and restricted units and performance share awards will reduce the shares available for grant under the 2019 Equity Plan by 4.25 shares for each share subject to an award, resulting in a total number of full-value share awards that may be issued under the 2019 Equity Plan to 535,294. Stock options and SARs are granted at an exercise price equal to the stock’s fair value at the date of grant, may not have a term in excess of ten years, and have vesting periods of five award either vests and is immediately payable, or is subject to additional time-based vesting, depending on the terms of the particular executive’s award agreement. The Company granted 84,019 equity awards to its employees in 2024, consisting of 57,060 shares of restricted stock, 19,929 performance stock units and 7,030 restricted stock units. The Company granted 120,116 equity awards to its employees in 2023, consisting of 79,140 shares of restricted stock, 28,346 performance share units and 12,630 restricted stock units.

The valuation model estimates fair value based on the assumptions for the risk-free rate, expected dividend yield, volatility and expected life. The risk-free rate is the interest rate available on zero-coupon U.S. Treasury instruments with a remaining term equal to the expected term of the share option at the time of grant. The expected dividend yield is based on the dividend trends and the market price of the Company’s stock price at grant. Volatility is largely based on historical volatility of the Company’s stock price. The expected term is based upon historical experience of employee exercises and terminations as the vesting term of the grants. The fair values of the grants are expensed over the vesting periods. There were no incentive stock options or SARs granted in 2024, 2023 or 2022.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company recognizes revenue in accordance with ASU No. 2014-09 Revenue from Contracts with Customers (ASC 606) and all subsequent ASUs that modified ASC 606. ASC 606 is applicable to the Company’s noninterest revenue streams including its deposit related fees, card services income, trust and management, and insurance commissions and fees. Noninterest revenue streams in-scope of Topic 606 are discussed below. Insurance Commissions and Fees Insurance commissions and fees from insurance product sales are typically earned upon the effective date of bound coverage, as no significant performance obligation remains after coverage is bound. Commission revenue on policies billed in installments is accrued based upon the completion of the performance obligation creating a current asset for the unbilled revenue until such time as an invoice is generated, typically not to exceed twelve months. Contingent commissions are estimated based upon management's expectations for the user with an appropriate constraint applied and accrued relative to the recognition of the corresponding core commissions. Trust & Asset Management Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end fair value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Mutual Fund & Investment Income Mutual fund and investment income consists of other recurring revenue streams such as commissions from sales of mutual funds and other investments, and investment advisory fees from the Company’s Strategic Asset Management Services wealth management product. Commissions from the sale of mutual funds and other investments are recognized on the trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees (i.e., trailers) from mutual fund companies typically based on a percentage of net asset value, recorded over time, usually monthly or quarterly, as net asset value is determined. Investment advisor fees from the wealth management product are earned over time and based on an annual percentage rate of the net asset value. The investment advisor fees are charged to the customer’s account in advance on the first month of the quarter, and the revenue is recognized over the following three-month period. The Company does engage a third party, LPL Financial, LLC (LPL), to satisfy part of this performance obligation, and therefore this income is reported net of any corresponding expenses paid to LPL. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Card Services Income Fees, exchange, and other service charges are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as MasterCard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. The Company’s performance obligation for fees and exchange are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Other Other service charges include revenue from processing wire and ACH transfers, lock box service and safe deposit box rental. Payment on these revenue streams is received primarily through a direct charge to the customer’s account, immediately or in the following month, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of ASC 606, for the years ended December 31, 2024, 2023, and 2022: Year ended December 31, (In thousands) 2024 2023 2022 Noninterest Income In-scope of Topic 606: Insurance Revenues $ 39,100 $ 37,351 $ 36,201 Investment Service Income 19,589 17,951 18,091 Service Charges on Deposit Accounts 7,288 6,913 7,365 Card Services Income 12,057 11,488 11,024 Other 1,296 1,324 1,291 Noninterest Income (in-scope of ASC 606) 79,330 75,027 73,972 Noninterest Income (out-of-scope of ASC 606) 8,797 (64,786) 4,000 Total Noninterest Income $ 88,127 $ 10,241 $ 77,972 Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration or before payment is due, which would result in contract receivables or assets, respectively. A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment or for which payment is due from the customer. The Company’s noninterest revenue streams, excluding some insurance commissions and fees, are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Receivables primarily consist of amounts due for insurance and wealth management services performed for which the Company's performance obligations have been fully satisfied. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. Contract Acquisition Costs In connection with the adoption of ASC 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of ASC 606, the Company did not capitalize any contract acquisition costs.

These net operating losses were fully utilized in 2024. The above analysis does not include recorded deferred tax assets (liabilities) of $33.9 million and $32.7 million as of December 31, 2024 and 2023, respectively, related to net unrealized holdings losses/(gains) in the available-for-sale debt securities portfolio. In addition, the analysis excludes recorded deferred tax assets of $5.6 million and $8.4 million, as of December 31, 2024 and 2023, respectively, related to employee benefit plans. Realization of deferred tax assets is dependent upon the generation of future taxable income or the existence of sufficient taxable income. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. In assessing the need for a valuation allowance, management considers the scheduled reversal of the deferred tax liabilities, the level of historical taxable income, and the projected future taxable income over the periods in which the temporary differences comprising the deferred tax assets will be deductible. Based on its assessment, management determined that no valuation allowance was necessary at December 31, 2024 and 2023. At December 31, 2024, December 31, 2022 and December 31, 2021, the Company had an insignificant amount of ASC 740-10 unrecognized tax benefits. The Company does not expect the total amount of unrecognized tax benefits to significantly increase within the next twelve months. The Company recognizes interest and penalties on unrecognized tax benefits in income tax expense in its Consolidated Statements of Income. The Company is subject to U.S. federal income tax and income tax in New York and various state jurisdictions. All tax years ending after December 31, 2020 are open to examination by the taxing authorities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities The Company, in the normal course of business, is a party to financial instruments with off-balance-sheet risk to meet the financial needs of its customers. These financial instruments include loan commitments, standby letters of credit, and unused portions of lines of credit. The contract, or notional amount, of these instruments represents the Company’s involvement in particular classes of financial instruments. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the Consolidated Statements of Condition. The Company’s maximum potential obligations to extend credit for loan commitments (unfunded loans, unused lines of credit, and standby letters of credit) outstanding on December 31 were as follows: (In thousands) 2024 2023 Loan commitments $ 152,255 $ 109,342 Standby letters of credit 38,525 39,089 Undisbursed portion of lines of credit 1,134,554 1,020,558 Total $ 1,325,334 $ 1,168,989 Commitments to extend credit (including lines of credit) are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Standby letters of credit are conditional commitments to guarantee the performance of a customer to a third party. The Company extends standby letters of credit to its customers in the normal course of business. The standby letters of credit are generally short-term. As of December 31, 2024, the Company’s maximum potential obligation under standby letters of credit was $38.5 million. Management uses the same credit policies in making commitments to extend credit and standby letters of credit as are used for on-balance-sheet lending decisions. Based upon management’s evaluation of the counterparty, the Company may require collateral to support commitments to extend credit and standby letters of credit. The credit risk amounts are equal to the contractual amounts, assuming the amounts are fully advanced and collateral or other security is of no value. The Company does not anticipate losses as a result of these transactions. These commitments also have off-balance-sheet interest-rate risk, in that the interest rate at which these commitments were made may not be at market rates on the date the commitments are fulfilled. Since some commitments and standby letters of credit are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. The Company may also have rate lock agreements associated with mortgage loans to be sold in the secondary market (certain of which relate to loan applications for which no formal commitment has been made). The amount of rate lock agreements at December 31, 2024 was immaterial. In order to limit the interest rate risk associated with rate lock agreements, as well as the interest rate risk associated with mortgages held for sale, if any, the Company enters into agreements to sell loans in the secondary market to unrelated investors on a loan-by-loan basis. At December 31, 2024, the Company had approximately $4,730,000 of commitments to sell mortgages to unrelated investors on a loan-by-loan basis.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. FASB ASC Topic 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are: Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 – Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of December 31, 2024 and 2023 segregated by the level of valuation inputs within the fair value hierarchy used to measure fair value: Recurring Fair Value Measurements December 31, 2024 (In thousands) (Level 1) (Level 2) (Level 3) Assets Available-for-sale debt securities U.S. Treasuries $ 71,497 $ 0 $ 71,497 $ 0 Obligations of U.S. Government sponsored entities 380,280 0 380,280 0 Obligations of U.S. states and political subdivisions 77,694 0 77,694 0 Mortgage-backed securities – residential, issued by: U.S. Government agencies 63,254 0 63,254 0 U.S. Government sponsored entities 636,360 0 636,360 0 U.S. corporate debt securities 2,447 0 2,447 0 Total Available-for-sale debt securities $ 1,231,532 $ 0 $ 1,231,532 $ 0 Equity securities, at fair value 768 0 0 768 Derivatives designated as hedging instruments 864 0 864 0 Derivatives not designated as hedging instruments 1,831 0 1,831 0 Liabilities Derivatives not designated as hedging instruments $ 2,073 $ 0 $ 2,073 $ 0 The change in the fair value of the $768,000 of equity securities valued using significant unobservable inputs (level 3), between January 1, 2024 and December 31, 2024 was immaterial.

Fair values for obligations of U.S. government sponsored entities, mortgage-backed securities-residential, obligations of U.S. states and political subdivisions, and U.S. corporate debt securities are based on quoted market prices, where available, as provided by third party pricing vendors. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments in active markets and/or based upon matrix pricing methodology, which uses comprehensive interest rate tables to determine market price, movement and yield relationships. These securities are reviewed periodically to determine if there are any events or changes in circumstances that would adversely affect their value. The Company determines fair value for its available-for-sale debt securities using an independent bond pricing service for identical assets or very similar securities. The pricing service uses a variety of techniques to determine fair value, including market maker bids, quotes and pricing models. Inputs to the model include recent trades, benchmark interest rates, spreads, and actual and projected cash flows. The Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, the Company’s investment portfolio consists of traditional investments, nearly all of which are U.S. Treasury obligations, federal agency bullet or mortgage pass-through securities, or general obligation municipal bonds. Pricing for such instruments is fairly generic and is easily obtained. Quarterly, the Company will validate prices supplied by the independent pricing service by comparing to prices obtained from a second third-party source. Based on the inputs used by our independent pricing services, the Company identifies the appropriate level within the fair value hierarchy to report these fair values. Derivatives: The Company has contracted with a third party vendor to provide periodic valuations for its interest rate derivatives to determine the fair value of its interest rate contracts. The vendor utilizes standard valuation methodologies applicable to interest rate derivatives such as discounted cash flow analysis. Such valuations are based upon readily observable market data and are therefore considered Level 2 valuations by the Company. Certain assets are measured at fair value on a nonrecurring basis, that is, they are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. For the Company, these include loans held for sale, collateral dependent individually evaluated loans, other real estate owned, goodwill and other intangible assets. During 2024, certain collateral dependent individually evaluated loans and other real estate owned at December 31, 2024, were adjusted down to fair value. Collateral values are estimated using Level 3 inputs based upon observable market data. Real estate values are generally valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally available in the market.

The following methods and assumptions were used in estimating fair value disclosures for financial instruments: Cash and Cash Equivalents: The carrying amounts reported in the Consolidated Statements of Condition for cash, noninterest-bearing deposits, money market funds, and Federal funds sold approximate the fair value of those assets. Securities - Held-to-Maturity: Fair values for U.S. Treasury securities are based on quoted market prices. Fair values for obligations of U.S. government sponsored entities, and mortgage-backed securities-residential are based on quoted market prices, where available, as provided by third party pricing vendors. If quoted market prices were not available, fair values are based on quoted market prices of comparable instruments in active markets and/or based upon a matrix pricing methodology, which uses comprehensive interest rate tables to determine market price, movement and yield relationships. These securities are reviewed periodically to determine if there are any events or changes in circumstances that would adversely affect their value. FHLB Stock and Other Stock: The carrying amount of FHLB stock approximates fair value. If the stock is redeemed, the Company will receive an amount equal to the par value of the stock. For miscellaneous equity securities, carrying value is cost. Loans and Leases: Fair value for loans is calculated using an exit price notion. The Company's valuation methodology takes into account factors such as estimated cash flows, including contractual cash flow and assumptions for prepayments; liquidity risk; and credit risk. The fair values of residential loans were estimated using discounted cash flow analyses, based upon available market benchmarks for rates and prepayment assumptions. The fair values of commercial and consumer loans were estimated using discounted cash flow analyses, based upon interest rates currently offered for loans and leases with similar terms and credit quality. The fair values of loans held for sale were determined based upon contractual prices for loans with similar characteristics. Accrued Interest Receivable and Accrued Interest Payable: The carrying amount of these short term instruments approximates fair value. Deposits: The fair values disclosed for noninterest bearing accounts and accounts with no stated maturities are equal to the amount payable on demand at the reporting date. The fair value of time deposits is based upon discounted cash flow analyses using rates offered for FHLB advances, which is the Company’s primary alternative source of funds. Fed Funds Purchased and Securities Sold Under Agreements to Repurchase: The carrying amount of these instruments approximates fair value because the instruments have short-term maturities. Other borrowings: The fair value of other borrowings is based upon discounted cash flow analyses using current rates offered for FHLB advances, with similar terms.

Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on the Company’s business, results of operation and financial condition. Under capital adequacy guidelines and the regulatory framework for prompt corrective action (PCA), banks must meet specific guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Capital amounts and classifications of the Company and its subsidiary bank are also subject to qualitative judgments by regulators concerning components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of common equity Tier I capital, total capital and Tier 1 capital to risk-weighted assets (as defined in the regulation), and of Tier 1 capital to average assets (as defined in the regulation). Management believes that the Company and its subsidiary bank meet all capital adequacy requirements to which they are subject. As of December 31, 2024, the most recent notifications from Federal bank regulatory agencies categorized the Company's subsidiary bank as "well capitalized" under the regulatory framework for PCA. To be categorized as well capitalized, the Company and its subsidiary bank must maintain total risk-based, Tier 1 risk-based, common equity Tier 1 capital and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the capital category of the Company or its subsidiary bank. In the first quarter of 2020, U.S. Federal regulatory authorities issued an interim final rule that provided banking organizations that adopt CECL during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition. The following table presents actual and required capital ratios as of December 31, 2024 and December 31, 2023 for Tompkins and its banking subsidiary. The minimum capital amounts required under Basel III include the capital conservation buffer of 2.5%, which must be added to each of the minimum required risk-based capital ratios (Total capital to risk-weighted assets, Common equity Tier 1 capital to risk-weighted assets and Tier 1 capital to risk weighted assets). Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. Actual capital amounts and ratios of the Company and its subsidiary bank are as follows: Actual Minimum Capital Required- Basel III Fully-Phased-In Required to be Considered Well Capitalized (dollar amounts in thousands) Amount/Ratio Amount/Ratio Amount/Ratio December 31, 2024 Total Capital (to risk-weighted assets) The Company (consolidated) $796,226 /13.1% $639,844/>10.5% $609,375/>10.0% Tompkins Community Bank $754,991/12.4% $638,719/>10.5% $608,304/>10.0% Common Equity Tier 1 Capital (to risk-weighted assets) The Company (consolidated) $738,266/12.1% $426,563/>7.0% $396,094/>6.5% Tompkins Community Bank $697,031/11.5% $425,813/>7.0% $395,398/>6.5% Tier 1 Capital (to risk-weighted assets) The Company (consolidated) $738,266/12.1% $517,969/>8.5% $487,500/>8.0% Tompkins Community Bank $697,031/11.5% $517,058/>8.5% $486,643/>8.0% Tier 1 Capital (to average assets) The Company (consolidated) $738,266/9.3% $318,498/>4.0% $398,123/>5.0% Tompkins Community Bank $697,031/8.8% $317,914/>4.0% $397,393/>5.0% December 31, 2023 Total Capital (to risk-weighted assets) The Company (consolidated) $754,792 /13.4% $593,213/>10.5% $564,965/>10.0% Tompkins Community Bank $721,297/12.8% $591,445/>10.5% $563,281/>10.0% Common Equity Tier 1 Capital (to risk-weighted assets) The Company (consolidated) $699,525/12.4% $395,476/>7.0% $367,227/>6.5% Tompkins Community Bank $666,030/11.8% $394,297/>7.0% $366,133/>6.5% Tier 1 Capital (to risk-weighted assets) The Company (consolidated) $699,525/12.4% $480,220/>8.5% $451,972/>8.0% Tompkins Community Bank $666,030/11.8% $478,789/>8.5% $450,625/>8.0% Tier 1 Capital (to average assets) The Company (consolidated) $699,525/9.1% $308,269/>4.0% $385,337/>5.0% Tompkins Community Bank $666,030/8.7% $307,956/>4.0% $384,945/>5.0%

Tompkins Financial Advisors has offices in each of the Company’s regional markets. Chief Operating Decision Maker Our Chief Executive Officer ("CEO") is our chief operating decision maker. In order to allocate costs, capital and resources to each operating segment, we (i) identify the cost or opportunity value of funds within each business segment, (ii) measure the profitability of a particular business segment by relating appropriate costs to revenues, (iii) evaluate each business segment in a manner consistent with its economic impact on consolidated earnings, and (iv) enhance asset and liability pricing decisions. Our CEO reviews actual net income versus budgeted net income on a monthly basis to assess segment performance and to make decisions about allocating capital and personnel among the segments. Summarized financial information concerning the Company’s reportable segments and the reconciliation to the Company’s consolidated results is shown in the following table. Investment in subsidiaries is netted out of the presentations below. The "Intercompany" column identifies the intercompany activities of revenues, expenses and other assets between the banking and financial services segments. The Company accounts for intercompany fees and services at an estimated fair value according to regulatory requirements for the services provided.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company also enters into interest rate derivatives to accommodate the business requirements of certain qualifying customers. All derivatives are recognized as other assets or other liabilities on the Company's Consolidated Statements of Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and resulting designation. Derivatives Designated as Hedging Instruments Fair Value Hedges of Interest Rate Risk The Company is exposed to changes in the fair value of certain of its fixed-rate assets due to changes in benchmark interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. As of December 31, 2024, the Company had interest rate swaps with a total notional amount of $150.0 million hedging fixed-rate residential mortgage loans. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. As of December 31, 2024 and December 31, 2023, the following amounts were recorded on the Consolidated Statements of Condition related to cumulative basis adjustment for fair value hedges. Line Item in the Statement of Financial Position in Which the Hedged Item is Included Carrying Amount of the Hedged Assets/(Liabilities) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets/(Liabilities) Carrying Amount of the Hedged Assets/(Liabilities) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets/(Liabilities) December 31, 2024 December 31, 2024 December 31, 2023 December 31, 2023 Fixed Rate Loans 1 $149,175 $(825) $148,633 $(1,367) Total $149,175 $(825) $148,633 $(1,367) 1 These amounts include the amortized cost basis of closed portfolios of fixed rate loans used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolio anticipated to be outstanding for the designated hedged period. At December 31, 2024 and December 31, 2023, the amortized cost basis of the closed portfolios used in these hedging relationships was $711.0 million and $763.4 million respectively; the cumulative basis adjustments associated with these hedging relationships was $825,000 and $1.4 million, respectively; and the amount of the designated hedged items was $150.0 million for both periods. Derivatives Not Designated as Hedging Instruments The Company enters into interest rate swaps to help commercial loan borrowers manage their interest rate risk. These interest rate swap contracts allow borrowers to convert variable-rate loan payments to fixed-rate loan payments. When the Company enters into an interest rate derivative contract with a commercial loan borrower, it simultaneously enters into a “mirror” interest rate contract with a third party. For interest rate swaps, the third party exchanges the client’s fixed-rate loan payments for variable-rate loan payments. The Company's credit policies with respect to interest rate contracts with commercial borrowers are similar to those used for loans. The Company retains the risk that is associated with the potential failure of counterparties and the risk inherent in originating loans. The interest rate contracts with counterparties are generally subject to bilateral collateralization terms. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings. The Company has entered into risk participation agreements with other banks in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings. Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Company assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Risk management and strategy The Company takes very seriously the responsibilities to protect sensitive information, technology resources, and shareholder value from the risk of cyber threats and incidents. The Company maintains an enterprise-wide and Board-approved Information and Cyber Security Program (the “Program”), which includes strategy, written policies, procedures, guidelines and standards to address the assessment, identification and management of cybersecurity risks. The Company designed the Program to be consistent with industry standards and in compliance with applicable federal and New York state laws, regulations and guidelines. As discussed in further detail under the subheading "Governance" below, the Program is fully integrated with the Company's overall enterprise risk management systems and processes. The Company has adopted the Factor Analysis for Information Risk (FAIR) assessment approach, an industry standard risk assessment methodology. Under the FAIR approach, the Company identifies, catalogs, assesses and manages material cyber risks by: (a) documenting threat actors and organizations (i.e., cybercriminals, nation state actors, hackers, company insiders), (b) analyzing their likelihood of attack, their motives, capabilities and tactics; (c) assessing the potential impacts of such threat actor attacks against company assets, and documented vulnerabilities (or cyber exposures), both internally and externally of the organization; and (d) evaluating the implemented security controls and effectiveness of those controls against defined risk scenarios. The Company rates vulnerabilities based on the criticality of a vulnerability and/or the value of the asset associated with the vulnerability (for example, people, systems, customer data, or money). When a residual risk exceeds the desired threshold set by the Board-defined risk appetite of the organization, additional controls are recommended and implemented to reduce the potential risk to an acceptable level and provide appropriate management of the cyber risk exposure. In conjunction with the FAIR assessment, the Company uses the MITRE Attack framework to identify the various exploitation techniques and tactics used by the most likely threat actors. This framework informs the risk management process with valuable insight into some of the most common, or likely, cyber-attacks the Company should address. Additionally, the Company leverages insights from independently-conducted penetration testing provided by external third-party assessors, as required by the NYSDFS cybersecurity regulations, to discover and evaluate potential vulnerabilities across the enterprise that should be contemplated within the overall cyber risk program. The Company also engages independent third-party auditors to provide additional subject matter expertise, as well as to perform comprehensive independent audits of the Program. Audits are conducted no less than annually to evaluate the effectiveness and maturity of the Program. Audits include a review of the cyber risk assessment process, security control effectiveness, and compliance with regulatory requirements. To manage the risks identified, the Company implements controls and tests those controls for effectiveness. The Company uses the Federal Financial Institutions Examination Council Cyber Assessment Tool (CAT), the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF), the NYSDFS cybersecurity requirements and the Center for Internet Security (CIS) Critical Controls to help inform the Company of best practices for control implementation and potential risk mitigation opportunities that align with defined risk scenarios, and generally as a baseline for best practice control implementation. As part of the Program, the Company has established policies and procedures to oversee, identify and mitigate material cybersecurity risks associated with the use of any third-party service providers. The Company evaluates and risk rates third-party relationships against a defined set of minimum-security requirements under its enterprise-wide Third-Party Risk Management program. Higher-risk third party service providers are reviewed in more detail and as part of the continual due diligence process to ensure changes to the relationship and/or risk posture are identified and managed appropriately. The Company is not aware of any cybersecurity incidents that have materially affected the Company, including its business strategy, results of operations or financial condition. For a discussion of cybersecurity threats that could materially affect the Company’s business strategy, results of operations or financial condition, please see Item 1A. Risk Factors.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis Of Presentation	Basis Of Presentation Tompkins Financial Corporation ("Tompkins" or "the Company") is registered as a Financial Holding Company with the Federal Reserve Board pursuant to the Bank Holding Company Act of 1956, as amended, organized under the laws of New York State. Tompkins is the parent company of Tompkins Community Bank, and Tompkins Insurance Agencies, Inc. ("Tompkins Insurance"). Tompkins Community Bank provides a full array of trust and investment services under the Tompkins Financial Advisors brand. Unless the context otherwise requires, the term "Company" refers to Tompkins Financial Corporation and its subsidiaries. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under GAAP. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, variable interest entities (VIEs) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when the Company has both the power and ability to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The consolidated financial statements have been prepared in accordance with GAAP. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclose contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the allowance for credit losses, valuation of goodwill and intangible assets, deferred income tax assets, and obligations related to employee benefits. The consolidated financial information included herein combines the results of operations, assets, liabilities, and shareholders’ equity (including comprehensive income or loss) of the Company and entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions are eliminated in consolidation. Amounts in the prior periods’ consolidated financial statements are reclassified when necessary to conform to the current periods’ presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents
Securities	Securities Management determines the appropriate classification of debt securities at the time of purchase. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity debt securities are stated at amortized cost. Debt securities not classified as held-to-maturity debt securities are classified as either available-for-sale or equity. Available-for-sale debt securities are stated at fair value with the unrealized gains and losses, net of tax, excluded from earnings and reported as a separate component of accumulated comprehensive income or loss, in shareholders’ equity. Certain equity securities that do not have a readily determinable fair value are stated at cost. Shares of stock of the Federal Home Loan Bank of New York, are also carried at cost. Premiums and discounts are amortized or accreted over the expected life or call date of the related security as an adjustment to yield using the interest method. Dividend and interest income are recognized when earned. Realized gains and losses on the sale of securities are included in net gain (loss) on securities transactions. The cost of securities sold is based on the specific identification method. For available-for-sale debt securities in an unrealized loss position, at least quarterly, the Company evaluates the securities to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit-related is recognized in other comprehensive income (loss), net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses ("ACL") on the Statements of Condition, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available-for-sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount must be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in this situation. Changes in the allowance for credit losses are recorded as provision (credit) for credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available-for-sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Accrued interest receivable on securities is excluded from the estimate of credit losses.
Loans and Leases	Loans and Leases Loans are reported at their principal outstanding balance, net of deferred loan origination fees and costs, and unearned income. The Company has the ability and intent to hold its loans for the foreseeable future, except for certain residential real estate loans held-for-sale. The Company provides motor vehicle and equipment financing to its customers through direct financing leases. These leases are carried at the aggregate of lease payments receivable, plus estimated residual values, less unearned income. Unearned income on direct financing leases is amortized over the lease terms, resulting in a level rate of return. Residential real estate loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Fair value is determined on the basis of the rates quoted in the secondary market. Net unrealized losses attributable to changes in market interest rates are recognized through a valuation allowance by charges to income. Loans are generally sold on a non-recourse basis with servicing retained. Any gain or loss on the sale of loans is recognized at the time of sale as the difference between the recorded basis in the loan and the net proceeds from the sale. The Company may use commitments at the time loans are originated or identified for sale to mitigate interest rate risk. The commitments to sell loans and the commitments to originate loans held-for-sale at a set interest rate, if originated, are considered derivatives under Accounting Standard Codification ("ASC") Topic 815, Derivatives and Hedging . The impact of the estimated fair value adjustment was not significant to the consolidated financial statements. Interest income on loans is accrued and credited to income based upon the principal amount outstanding. Loan origination fees and costs are deferred and recognized over the life of the loan as an adjustment to yield. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments are due. Loans and leases, including individually evaluated loans, are generally classified as nonaccrual if they are past due as to maturity or payment of principal or interest for a period of more than 90 days, unless such loans are well secured and in the process of collection. Loans that are past due less than 90 days may also be classified as nonaccrual if repayment in full of principal or interest is in doubt. Loans may be returned to accrual status when all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within an acceptable time period, and there is a sustained period (generally six consecutive months) of repayment performance by the borrower in accordance with the contractual terms of the loan agreement. When interest accrual is discontinued, all unpaid accrued interest is reversed. Payments received on loans on nonaccrual are generally applied to reduce the principal balance of the loan. In general, the principal balance of a loan is charged off in full or in part when management concludes, based on the available facts and circumstances, that collection of principal in full is not probable. For commercial and commercial real estate loans, this conclusion is generally based upon a review of the borrower’s financial condition and cash flow, payment history, economic conditions, and the conditions in the various markets in which the collateral, if any, may be liquidated. In general, consumer loans are charged-off in accordance with regulatory guidelines which provide that such loans be charged-off when the Company becomes aware of the loss, such as from a triggering event that may include new information about a borrower’s intent/ability to repay the loan, bankruptcy, fraud or death, among other things, but in no case will the charge-off exceed specified delinquency timeframes. Such delinquency timeframes state that closed-end retail loans (loans with pre-defined maturity dates, such as real estate mortgages, home equity loans and consumer installment loans) that become past due 120 cumulative days and open-end retail loans (loans that roll-over at the end of each term, such as home equity lines of credit) that become past due 180 cumulative days should be classified as a loss and charged-off. For residential real estate loans, charge-off decisions are based upon past due status, current assessment of collateral value, and general market conditions in the areas where the properties are located.
Acquired Loans	Acquired Loans Acquired loans are recorded at fair value at the date of acquisition based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Certain larger purchased loans are individually evaluated while other purchased loans are grouped together according to similar risk characteristics and are treated in the aggregate when applying various valuation techniques. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change.
Allowance for Credit Losses - Loans	Allowance for Credit Losses – Loans The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis. Expected credit losses are reflected in the ACL through a charge to the provision for credit loss expense. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the ACL is reduced by the same amount. In general, the principal balance of a loan is charged off in full or in part when management concludes, based on the available facts and circumstances, that collection of principal in full is not probable. In addition, the Company has reserves for expected recoveries where the Company reviews the prior four quarter charge-offs and applies a recovery rate based on the Company’s historical experience. Subsequent recoveries, if any, are credited to the ACL when received. The Company measures expected credit losses of financial assets at the loan level by segment, by pooling loans when the financial assets share similar risk characteristics. Depending on the nature of the pool of financial assets with similar risk characteristics, the Company uses a discounted cash flow ("DCF") method to estimate the expected credit losses. Allowance on loans that do not share risk characteristics are evaluated on an individual basis. The Company assigns a credit risk rating to all commercial and commercial real estate loans. The Company reviews commercial and commercial real estate loans rated Substandard or worse, on nonaccrual, and greater than $250,000 for loss potential and when deemed appropriate, assigns an allowance based on an individual evaluation. The Company’s methodologies for estimating the ACL consider available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The methodologies apply historical loss information, adjusted for asset-specific characteristics, economic conditions at the measurement date, and forecasts about future economic conditions expected to exist through the contractual lives of the financial assets that are reasonable and supportable, to the identified pools of financial assets with similar risk characteristics for which the historical loss experience was observed. The Company’s methodologies revert back to average historical loss information on a straight line basis over eight quarters when it can no longer develop reasonable and supportable forecasts. The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: commercial, commercial real estate, residential, home equity, consumer and leases. This segmentation was selected based on the differences in the risk profile of each of these categories and aligns well with regulatory reporting categories. This segmentation separates borrower type, collateral type and the nature of the loan. The differences in risk profiles of these segments enable the ACL to be more precise in its allocation due to the inherent risk in these specific portfolios. Discounted Cash Flow Method The Company uses the DCF method to estimate expected credit losses for the commercial, commercial real estate, residential, home equity, and consumer loan pools. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for exposure at default using estimated prepayment speeds, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, and time to recovery are based on historical internal data. The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loan pools utilizing the DCF method, management utilizes and forecasts national unemployment and a one-year percentage change in national gross domestic product as loss drivers in the model. For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over eight quarters on a straight-line basis. Management leverages economic projections from an independent third party to inform its loss driver forecasts over the four-quarter forecast period. Other internal and external indicators of economic forecasts, and scenario weightings, are also considered by management when developing the forecast metrics. The model considers a base case forecast and two alternative forecasts and assigns weightings to these three scenarios based on current conditions and expectations for future conditions. The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows ("NPV"). An ACL is established for the difference between the instrument’s NPV and amortized cost basis. The model also considers the need to qualitatively adjust expected loss estimates for information not already captured in the loss estimation process. These qualitative factors include, but are not limited to, those suggested by the Interagency Policy Statement on Allowances for Credit Losses. These qualitative factor adjustments may increase or decrease the Company's estimate of expected credit losses. Due to the size and characteristics of the leasing portfolio, the remaining life method, using the historical loss rate of the commercial and industrial segment, is used to determine the allowance for credit losses. Individually Evaluated Financial Assets Loans that do not share common risk characteristics are evaluated on an individual basis. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral less cost to sell, and the amortized cost basis of the asset as of the measurement date. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. For acquired credit impaired loans accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, ("ASC Topic 310-30"), the Company’s allowance for loan and lease losses was estimated based upon our expected cash flows for these loans. To the extent that we experienced a deterioration in borrower credit quality resulting in a decrease in our expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on our estimate of future credit losses over the remaining life of the loans. For acquired non-credit impaired loans accounted for under FASB ASC Topic 310-20, Nonrefundable Fees and Other Costs, ("ASC Topic 310-20"), the Company’s allowance for loan and lease losses was maintained through provisions for loan losses based upon an evaluation process that was similar to our evaluation process used for originated loans. In conducting this evaluation, which included a review of loans on which full collectability may not be reasonably assured, the Company considered, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan loss experience, carrying value of the loans, which included the remaining net purchase discount or premium, and other factors that warrant recognition in determining our allowance for loan losses. The Company adopted Accounting Standard Update ("ASU") 2016-13 on January 1, 2020, using the prospective transition approach for financial assets purchased with credit deterioration ("PCD") that were previously classified as purchased credit impaired ("PCI") and accounted for under ASC 310-30. In accordance with the standard, the Company did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The remaining discount on the PCD assets will be accreted into interest income on a level-yield method over the life of the loans. Loan Modifications The Company adopted ASU 2022-02 effective January 1, 2023. This standard eliminated the previous troubled debt restructuring ("TDR") accounting model and replaced it with guidance and disclosure requirements for identifying modifications to loans to borrowers experiencing financial difficulty. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearances, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, unused lines of credit and commercial letters of credit, issued to meet customer financing needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancellable, through a charge to the provision for credit loss expense for off-balance sheet credit exposures included in other noninterest expense in the Company’s Consolidated Statements of Income. The ACL on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using similar methodologies as portfolio loans, taking into consideration the likelihood that funding will occur, and is included in other liabilities on the Company’s Statements of Condition.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, less allowances for depreciation. The provision for depreciation for financial reporting purposes is computed generally by the straight-line method at rates sufficient to write-off the cost of such assets over their estimated useful lives. Buildings are amortized over a period of 10-39 years, and furniture, fixtures, and equipment are amortized over a period of 2-20 years. Leasehold improvements are generally depreciated over the lesser of the lease term or the estimated lives of the improvements. Maintenance and repairs are charged to expense as incurred. Gains or losses on disposition are reflected in earnings.
Leases	Leases The Company leases certain office facilities and office equipment under operating leases. The Company also owns certain office facilities which it leases to outside parties under operating lessor leases; however, such leases are not significant. For operating leases other than those considered to be short-term, defined as leases of 12 months or less, the Company recognizes operating lease right-of-use ("ROU") assets and related lease liabilities at the time of lease commencement. ROU assets represent the Company's right to use the underlying asset for the lease term and the lease liabilities represent the Company's obligation to make lease payments under the leases. ROU assets and operating lease liabilities are reported as components of accrued interest and other assets and other liabilities, respectively, on our accompanying consolidated balance sheets. Leases with terms of 12 months or less are recognized in the income statement over the lease term. In recognizing ROU assets and related lease liabilities, the Company accounts for lease and non-lease components (such as taxes, insurance, and common area maintenance costs) separately as such amounts are generally readily determinable under our lease contracts. To estimate the present value of lease payments over the expected lease term, the Company uses interest rates on advances from the FHLB at the time of commencement. The Company's lease term may include options to extend or terminate the leases when it is reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term and is included in net occupancy expense of premises in the Company's Consolidated Statements of Income.
Bank Owned Life Insurance	Bank Owned Life Insurance The Company owns life insurance policies on certain current and former employees and directors where the Bank is the beneficiary. Bank owned life insurance ("BOLI") is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value (“CSV”) adjusted for other charges or other amounts due that are probable at settlement. Increases in the CSV of the policies, as well as the death benefits received, net of any CSV, are recorded in noninterest income, and are not subject to income taxes.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned consists of properties formerly pledged as collateral to loans, which have been acquired by the Company through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Upon transfer of a loan to foreclosure status, an appraisal is generally obtained and any excess of the loan balance over the fair value, less estimated costs to sell, is charged against the allowance for credit losses. Expenses and subsequent adjustments to the fair value are treated as other operating expense.
Goodwill	Goodwill Goodwill represents the excess of purchase price over the fair value of assets acquired in a transaction using purchase accounting. Goodwill has an indefinite useful life and is not amortized, but is tested for impairment. Goodwill impairment tests are performed on an annual basis or when events or circumstances dictate. On January 1, 2020, the Company adopted ASU 2017-04 , "Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment", which eliminates an entity's requirement to compute the implied fair value. The Company tests goodwill annually as of December 31 st . The Company has the option to perform a qualitative assessment of goodwill, which considers company-specific and economic characteristics that might impact its carrying value. If, based on this qualitative assessment, it is more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative test (Step 1) is performed, which compares the fair value of the reporting unit to the carrying amount of the reporting unit in order to identify potential impairment. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not considered impaired. The implied fair value of goodwill is determined in the same manner as goodwill that is recognized in a business combination. Significant judgment and estimates are involved in estimating the fair value of the assets and liabilities of the reporting units.
Other Intangible Assets	Other Intangible Assets Other intangible assets include core deposit intangibles, customer related intangibles, covenants not to compete, and mortgage servicing rights. Core deposit intangibles represent a premium paid to acquire a base of stable, low cost deposits in the acquisition of a bank, or a bank branch, using purchase accounting. The amortization period for core deposit intangible ranges from 5 to 10 years, using an accelerated method. The covenants not to compete are amortized on a straight-line basis over 3 to 6 years, while customer related intangibles are amortized on an accelerated basis over a range of 6 to 15 years. The amortization period is monitored to determine if circumstances require such periods to be revised. The Company periodically reviews its intangible assets for changes in circumstances that may indicate the carrying amount of the asset is impaired. The Company tests its intangible assets for impairment on an annual basis or more frequently if conditions indicate that an impairment loss has more likely than not been incurred.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are reviewed quarterly and reduced by a valuation allowance if, based upon the information available, it is more likely than not that some or all of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. In such cases, although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense in the Consolidated Statements of Income.
Tax Credit Investments	Tax Credit Investments income tax expense
Securities Sold Under Agreements to Repurchase	Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase (repurchase agreements) are agreements in which the Company transfers the underlying securities to a third-party custodian’s account that explicitly recognizes the Company’s interest in the securities. The agreements are accounted for as secured financing transactions provided the Company maintains effective control over the transferred securities and meets other criteria as specified in FASB ASC Topic 860, Transfers and Servicing ("ASC Topic 860"). The Company’s agreements are accounted for as secured financings; accordingly, the transaction proceeds are reflected as liabilities and the securities underlying the agreements continue to be carried in the Company’s securities portfolio.
Treasury Stock	Treasury Stock The cost of treasury stock is shown on the Consolidated Statements of Condition as a separate component of shareholders’ equity, and is a reduction to total shareholders’ equity. Shares are released from treasury at fair value, identified on an average cost basis.
Trust and Investment Services	Trust and Investment Services Assets held in fiduciary or agency capacities for customers are not included in the accompanying Consolidated Statements of Condition, since such items are not assets of the Company. Fees associated with providing trust and investment services are included in noninterest income. Additional information on trust and investment fees is presented in "Note 13 - Revenue Recognition."
Earnings Per Share	Earnings Per Share Basic earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares outstanding during the year, exclusive of shares represented by the unvested portion of restricted stock and restricted stock units. Diluted earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares outstanding during the year plus the dilutive effect of the unvested portion of restricted stock and restricted stock units and stock issuable upon conversion of common stock equivalents (primarily stock options) or certain other contingencies. The Company uses authoritative accounting guidance under ASC Topic 260, Earnings Per Share , which provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. The Company has issued stock-based compensation awards that included restricted stock awards that contain such rights and are thus considered participating securities. The Company has also issued restricted stock awards that do not contain non-forfeitable rights to dividends or dividend equivalents.
Segment Reporting	Segment Reporting
Comprehensive Income (Loss)	Comprehensive Income (Loss) For the Company, comprehensive income (loss) represents net income plus the net change in unrealized gains or losses on available-for-sale debt securities for the period (net of taxes), and the actuarial gain or loss and amortization of unrealized amounts in the Company’s defined-benefit retirement and pension plan, supplemental employee retirement plan, and post-retirement life and healthcare benefit plan (net of taxes), and is presented in the Consolidated Statements of Comprehensive Income (Loss) and Consolidated Statements of Changes in Shareholders’ Equity. Accumulated other comprehensive income (loss) represents the net unrealized gains or losses on available-for-sale debt securities (net of tax) and unrecognized net actuarial gain or loss, unrecognized prior service costs, and unrecognized net initial obligation (net of tax) in the Company’s defined-benefit retirement and pension plan, supplemental employee retirement plan, and post-retirement life and healthcare benefit plan.
Pension and Other Employee Benefits	Pension and Other Employee Benefits The Company maintains noncontributory defined-benefit and defined contribution plans, which cover substantially all employees of the Company. In addition, the Company also maintains supplemental employee retirement plans for certain executives and a post-retirement life and healthcare plan. These plans are discussed in detail in "Note 10 - Employee Benefit Plans". The Company incurs certain employment-related expenses associated with these plans. In order to measure the expense associated with these plans, various assumptions are made including the discount rate used to value certain liabilities, expected return on plan assets, anticipated mortality rates, and expected future healthcare costs. The assumptions are based on historical experience as well as current facts and circumstances. A third-party actuarial firm is used to assist management in measuring the expense and liability associated with the plans. The Company uses a December 31 measurement date for its plans. As of the measurement date, plan assets are determined based on fair value, generally representing observable market prices. The projected benefit obligation is primarily determined based on the present value of projected benefit distributions at an assumed discount rate. The expenses associated with these plans are charged to current operating expenses. The Company recognizes an asset for a plan’s overfunded status or a liability for a plan’s underfunded status in the Company’s consolidated statements of condition, and recognizes changes in the funded status of these plans in comprehensive income, net of applicable taxes, in the year in which the change occurred.
Stock-Based Compensation	Stock-Based Compensation The Company's current stock-based compensation plan provides for stock options, stock appreciation rights ("SARs"), restricted stock awards, restricted stock units and performance share units. Compensation expense for awards is recognized over the service period based on the fair value at the date of grant and is included in salaries and employee benefits expense in the Consolidated Statements of Income. Grant date fair value for SARs is estimated using the Black-Scholes option-pricing model. Awards of restricted stock awards, restricted stock units and performance share units are valued at the fair market value of the Company's common stock as of the award date. Compensation expense for performance share units is estimated based on the probability that the performance conditions will be achieved. The likelihood that the performance conditions will be met is assessed each reporting period. Forfeitures are recognized when they occur. Vested equity awards are issued from authorized but unissued stock. Excess tax benefits (expenses) result when tax return deductions differ from recognized share-based compensation cost that are determined using the grant-date fair value approach for financial statement purposes. Excess tax benefits (expenses) related to the settlement of share-based awards are recorded as a decrease (increase) to income tax expense in the Consolidated Income Statements and are classified in the Consolidated Statements of Cash Flows as an operating activity.
Fair Value Measurements	Fair Value Measurements The Company accounts for the provisions of FASB ASC Topic 820, Fair Value Measurements and Disclosures ("ASC Topic 820"), for financial assets and financial liabilities. ASC Topic 820 defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. See "Note 18 - Fair Value Measurements". In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among others.
Revenue Recognition	Revenue Recognition
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company also enters into interest rate derivatives to accommodate the business requirements of certain qualifying customers. All derivatives are recognized as other assets or other liabilities on the Company's Consolidated Statements of Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and resulting designation. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. The Company has entered into risk participation agreements with other banks in commercial loan arrangements. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings. Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Company assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank.
Newly Adopted Accounting Standards and Accounting Standards Pending Adoption	Newly Adopted Accounting Standards ASU No. 2023-02, "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." This update will allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits or other income tax benefits. This update applies to all reporting entities that hold (1) tax equity investments that meet the conditions for and elect to account for them using the proportional amortization method or (2) an investment in a low income housing tax credit ("LIHTC") structure through a limited liability entity that is not accounted for using the proportional amortization method and to which certain LIHTC specific guidance removed from Subtopic 323-740 has been applied. Additionally, the disclosure requirements apply to investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method (including investments within that elected program that do not meet the conditions to apply the proportional amortization method). The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. ASU 2023-02 is effective for fiscal years beginning after December 15, 2023 and interim periods in those years. The adoption of ASU 2023-02 on January 1, 2024 did not have a material effect on the Company's financial statements. Transition for existing tax credits that qualify must be recognized using either a modified retrospective transition or a retrospective transition for all existing tax investments still expected to provide tax benefits and elected under ASU 2023-02 to apply the proportional amortization method. The Company has elected to treat all existing tax credit investments requiring adjustment under ASU 2023-02 using the modified retrospective method approach. The Company had recorded 2 investments in separate LIHTC structures as of December 31, 2024 totaling $2.1 million already using proportional amortization, with a $57,000 benefit recorded to income tax expense in the fiscal year ending December 31, 2024 and $54,000 benefit for the fiscal year ending December 31, 2023. In addition, the Company has a historic rehabilitation tax credit that was previously recorded using the equity investment accounting method and had no residual book value or financial impact in either the current or prior year. The ASU 2023-02 day 1 adoption entry for this tax credit included the recording of a $40,000 investment and the write-off of a $444,000 gross timing difference (tax effective at $111,000) with a corresponding $71,000 reduction to retained earnings. The Company has also elected to treat the following categories of tax credit investments under the proportional amortization method: • LIHTC - Low Income Housing Tax Credits • New Market Tax Credits • Historic Rehabilitation Tax Credit • Renewable Energy Tax Credit • State Specific Tax Credits ASU No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis. The amendments in this ASU are effective for the Company for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Adoption did not have a significant effect on our financial statements or disclosures. Accounting Standards Pending Adoption ASU No. 2023-06, Disclosure Improvements , amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. The new guidance is intended to align GAAP requirements with those of the SEC. The ASU will become effective on the earlier of the date on which the SEC removes its disclosure requirements from Regulation S-X or Regulation S-K, or June 30, 2027. Early adoption is prohibited. Adoption of ASU 2023-06 is not expected to have a material impact on our consolidated financial statements. ASU No. 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures." The amendments in this update relate to the rate reconciliation and income taxes paid disclosures improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 and interim periods in those years. Tompkins is currently evaluating the potential impact of ASU 2023-09 on our consolidated financial statements. ASU No. 2024-03, "Disaggregation of Income Statement Expenses, " requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense captions, including employee compensation, depreciation, and intangible asset amortization. Tompkins is required to adopt this ASU prospectively for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption and retrospective application are permitted. The Company reviews new accounting standards as issued. Management has not identified any other new standards that it believes will have a significant impact on the Company’s financial statements.
