Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements included in this quarterly report do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles ("GAAP") for a full year presentation and certain disclosures have been condensed or omitted in accordance with rules and regulations of the SEC. In the application of certain accounting policies, management is required to make assumptions regarding the effect of matters that are inherently uncertain. These estimates and assumptions affect the reported amounts of certain assets, liabilities, revenues, and expenses in the unaudited consolidated financial statements. Different amounts could be reported under different conditions, or if different assumptions were used in the application of these accounting policies. The accounting policy that management considers critical in this respect is the determination of the allowance for credit losses. In management’s opinion, the unaudited consolidated financial statements reflect all adjustments of a normal recurring nature. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year ended December 31, 2024. The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. Cash and cash equivalents in the consolidated statements of cash flow include cash and noninterest bearing balances due from banks, interest-bearing balances due from banks, 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. The Company has evaluated subsequent events for potential recognition and/or disclosure, and determined that no further disclosures were required. The consolidated financial information included herein combines the results of operations, the assets, liabilities, and shareholders’ equity of the Company and its subsidiaries. Amounts in the prior periods’ unaudited consolidated financial statements are reclassified when necessary to conform to the current periods’ presentation. All significant intercompany balances and transactions are eliminated in consolidation. 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 this 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 currently has recorded investments in 2 separate LIHTC structures as of June 30, 2024 totaling $2.2 million already using proportional amortization with a $32,000 benefit recorded to income tax expense in the six months ending June 30, 2024 and $27,000 benefit for the six months ending June 30, 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 Accounting Standards Pending Adoption 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. ASU 2023-07 is effective for fiscal years beginning after December 15, 2024 and interim periods in those years, and its adoption is not expected to have a significant effect on our financial statements or disclosures. ASU No. 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures." The amendments in this Update related 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. 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.

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 (technical impairment) 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 Consolidated 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 June 30, 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, the Federal Home Loan Bank ("FHLB") 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 June 30, 2024 or December 31, 2023. The gross unrealized losses reported for residential mortgage-backed securities relate to investment securities issued by U.S. government sponsored entities such as Federal National Mortgage Association, Federal Home Loan Mortgage Corporation, and U.S. government agencies such as Government National Mortgage Association. 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 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.

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 $41.3 million and $95,000, respectively, at June 30, 2024. These securities are carried at par, which is also cost. The FHLBNY continues to pay dividends and repurchase stock. Quarterly, we evaluate our investment in the FHLB for impairment. We evaluate recent and long-term operating performance, liquidity, funding and capital positions, stock repurchase history, dividend history and impact of legislative and regulatory changes. Based on our most recent evaluation, as of June 30, 2024, we determined that no impairment write-downs were required.

Management reviews these policies and procedures on a regular basis. The Company discussed its lending policies and underwriting guidelines for its various lending portfolios in Note 3 – "Loans and Leases" in the Notes to Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no significant changes in these policies and guidelines since the date of that report. As such, these policies are reflective of new originations as well as those balances held at December 31, 2023. 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 origination, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments are due. Generally loans are placed on nonaccrual status if principal or interest payments become 90 days or more past due and/or management deems the collectability of the principal and/or interest to be in question as well as when required by regulatory agencies. 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 due are brought current, the borrower has established a payment history, and future payments are reasonably assured. When management determines that the collection of principal in full is not probable, 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	6 Months Ended
	Jun. 30, 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 Discounted Cash Flow ("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 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 June 30, 2024 considers the allowance to be appropriate, under certain 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 judgements 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. The following tables detail activity in the allowance for credit losses on loans for the three and six months ended June 30, 2024 and 2023. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per share in the table below, for the three and six month periods ended June 30, 2024 and 2023 are calculated under the two-class method as required by ASC Topic 260, Earnings Per Share (ASC 260). ASC 260 provides that unvested share-based payment awards that contain nonforfeitable rights to dividends are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. Prior to 2019, the Company issued restricted stock awards that contained such rights and are therefore considered participating securities. Since 2019, the Company has issued restricted stock awards that do not have nonforfeitable rights to dividends and are therefore not considered participating securities. Basic earnings per common share are calculated by dividing net income allocable to common stock by the weighted average number of common shares, excluding participating securities, during the period.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition As stated in Note 1 - "Summary of Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, the Company adopted adopted ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers on January 1, 2022. The update relates to the previous adoption of ASC 606, "Revenue from Contracts with Customers" and all subsequent ASUs that modified ASC 606, and will be applied to future acquisitions. As there were no acquisitions during the current year, the adoption of ASU No. 2021-08 had no effect on the financial statements for the current fiscal year. Generally, this guidance strives to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity and inconsistency amongst entities in measuring contract assets and liabilities. The update requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 as if it had originated the contract. Changes in the acquiree’s balance of contract asset and contract liabilities identified as necessary to conform to the acquirer’s accounting policies would result in a reallocation of the purchase price. ASC 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of ASC 606. ASC 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. However, the recognition of these revenue streams did not change significantly upon adoption of ASC 606. 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 now 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. The impact of these changes was not significant, but it will result in slight variances from quarter to quarter. Contingent commissions are estimated based upon management’s expectations for the year 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 market 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 The Company also earns transaction fees and commissions related to product sales that represent the Company’s share of transaction fees resulting from investment services and programs provided through an agent relationship with a third-party broker-dealer. Those fees are collected and recognized on a monthly basis. Trailing fees are based upon fair values and are assessed, collected and recognized on a quarterly basis. Tompkins Community Bank acts as an agent in arranging the relationship between the customer and the third-party provider and does not control the services rendered; therefore, investment product sales commissions and fees are reported net of related costs. 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.

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. Receivables for the insurance and wealth management services segments amounted to $4.5 million and $3.5 million, respectively, at June 30, 2024, compared to $5.7 million and $3.0 million, respectively, at December 31, 2023. Included in those amounts are contract assets related to contingent income of $1.3 million and $2.8 million, respectively, at June 30, 2024 and December 31, 2023, and contract liabilities of $2.8 million and $1.9 million, respectively, at June 30, 2024 and December 31, 2023.

Guarantees [Abstract]
Financial Guarantees	Financial Guarantees The Company currently does not issue any guarantees that would require liability recognition or disclosure, other than standby letters of credit. 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 June 30, 2024, the Company’s maximum potential obligation under standby letters of credit was $31.6 million compared to $39.1 million at December 31, 2023. Management uses the same credit policies to extend standby letters of credit that it uses for on-balance sheet lending decisions and may require collateral to support standby letters of credit based upon its evaluation of the counterparty. Management does not anticipate any significant losses as a result of these transactions, and has determined that the fair value of standby letters of credit is not significant.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820) , defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. ASC 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). Transfers between levels, when determined to be appropriate, are recognized at the end of each reporting period. The three levels of the fair value hierarchy under ASC 820 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 tables summarize financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2024 and December 31, 2023, segregated by the level of valuation inputs within the fair value hierarchy used to measure fair value: Recurring Fair Value Measurements June 30, 2024 (In thousands) Total (Level 1) (Level 2) (Level 3) Assets Available-for-sale debt securities U.S. Treasuries $ 109,886 $ 0 $ 109,886 $ 0 Obligations of U.S. Government sponsored entities 422,677 0 422,677 0 Obligations of U.S. states and political subdivisions 78,476 0 78,476 0 Mortgage-backed securities – residential, issued by: U.S. Government agencies 40,112 0 40,112 0 U.S. Government sponsored entities 663,940 0 663,940 0 U.S. corporate debt securities 2,367 0 2,367 0 Total Available-for-sale debt securities $ 1,317,458 $ 0 $ 1,317,458 $ 0 Equity securities, at fair value 766 0 0 766 Derivatives designated as hedging instruments 2,487 0 2,487 0 Derivatives not designated as hedging instruments 851 0 851 0 Liabilities Derivatives not designated as hedging instruments $ 1,001 $ 0 $ 1,001 $ 0 Recurring Fair Value Measurements December 31, 2023 (In thousands) Total (Level 1) (Level 2) (Level 3) Assets Available-for-sale debt securities U.S. Treasuries $ 109,904 $ 0 $ 109,904 $ 0 Obligations of U.S. Government sponsored entities 456,458 0 456,458 0 Obligations of U.S. states and political subdivisions 81,924 0 81,924 0 Mortgage-backed securities – residential, issued by: U.S. Government agencies 45,240 0 45,240 0 U.S. Government sponsored entities 720,830 0 720,830 0 U.S. corporate debt securities 2,294 0 2,294 0 Total Available-for-sale debt securities $ 1,416,650 $ 0 $ 1,416,650 $ 0 Equity securities, at fair value 787 0 0 787 Derivatives designated as hedging instruments 1,503 0 1,503 0 Derivatives not designated as hedging instruments 1,610 0 1,610 0 Liabilities Derivatives not designated as hedging instruments $ 1,826 $ 0 $ 1,826 $ 0 Securities: Fair values for U.S. Treasury securities are based on quoted market prices. 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 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. The change in the fair value of equity securities valued using significant unobservable inputs (level 3), for the periods ended June 30, 2024 and December 31, 2023, was immaterial. There were no transfers between Levels 1, 2 and 3 for the six months ended June 30, 2024. 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 Company determines fair value for its equity securities based on the underlying equity fund’s pricing and valuation procedures which consider recent sales price, market quotations from a pricing service, or market quotes from an independent broker-dealer. The Company has reviewed the pricing sources, including methodologies used, and finds them to be fairly stated. 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. For the Company, these include loans held for sale, individually evaluated loans, and other real estate owned ("OREO"). For the three and six months ended June 30, 2024, certain individually evaluated loans were remeasured and reported at fair value through a specific valuation allowance and/or partial charge-offs for credit losses based upon the fair value of the underlying collateral. Collateral values are estimated using Level 3 inputs based upon customized discounting criteria. In addition to collateral dependent evaluated loans, certain other real estate owned was remeasured and reported at fair value based upon the fair value of the underlying collateral. The fair values of other real estate owned are estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. In general, the fair values of other real estate owned are based upon appraisals, with discounts made to reflect estimated costs to sell the real estate. Upon initial recognition, fair value write-downs are taken through a charge-off to the allowance for credit losses. Subsequent fair value write-downs on other real estate owned are reported in other noninterest expense.

For loans 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 loan 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 and the amortized cost basis of the loan as of the measurement date. For real estate loans, fair value of the loan’s collateral is determined by third party appraisals, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 8% of the appraised value. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business. The following tables present the carrying amounts and estimated fair values of the Company’s financial instruments at June 30, 2024 and December 31, 2023. The carrying amounts shown in the tables are included in the Consolidated Statements of Condition under the indicated captions.

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 are 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 approximate 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 approximate 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.

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 June 30, 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 June 30, 2024 and December 31, 2023, the following amounts were recorded on the balance sheet 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) June 30, 2024 June 30, 2024 December 31, 2023 December 31, 2023 Fixed Rate Loans 1 $147,620 $(2,380) $148,633 $(1,367) Total $147,620 $(2,380) $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 June 30, 2024 and December 31, 2023, the amortized cost basis of the closed portfolios used in these hedging relationships was $736.1 million and $763.4 million respectively; the cumulative basis adjustments associated with these hedging relationships was $2.4 million and $1.4 million, respectively; and the amounts of the designated hedged items were $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.

Accounting Policies [Abstract]
Newly Adopted Accounting Standards	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 this 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 currently has recorded investments in 2 separate LIHTC structures as of June 30, 2024 totaling $2.2 million already using proportional amortization with a $32,000 benefit recorded to income tax expense in the six months ending June 30, 2024 and $27,000 benefit for the six months ending June 30, 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 Accounting Standards Pending Adoption 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. ASU 2023-07 is effective for fiscal years beginning after December 15, 2024 and interim periods in those years, and its adoption is not expected to have a significant effect on our financial statements or disclosures. ASU No. 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures." The amendments in this Update related 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. 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.

Earnings Per Share [Abstract]
Schedule of basic and diluted earnings per share	Earnings per share in the table below, for the three and six month periods ended June 30, 2024 and 2023 are calculated under the two-class method as required by ASC Topic 260, Earnings Per Share (ASC 260). ASC 260 provides that unvested share-based payment awards that contain nonforfeitable rights to dividends are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. Prior to 2019, the Company issued restricted stock awards that contained such rights and are therefore considered participating securities. Since 2019, the Company has issued restricted stock awards that do not have nonforfeitable rights to dividends and are therefore not considered participating securities. Basic earnings per common share are calculated by dividing net income allocable to common stock by the weighted average number of common shares, excluding participating securities, during the period. Diluted earnings per common share include the dilutive effect of participating securities.
