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 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 condensed 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 policies that management considers critical in this respect are the determination of the allowance for loan and lease losses, the expenses and liabilities associated with the Company’s pension and post-retirement benefits, and the review of its securities portfolio for other than temporary impairment. In management’s opinion, the unaudited condensed 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, 2017 . The unaudited condensed 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, 2016 . There have been no significant changes to the Company’s accounting policies from those presented in the 2016 Annual Report on Form 10-K. Refer to Note 3- “Accounting Standards Updates” of this Report for a discussion of recently issued accounting guidelines. 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 condensed consolidated financial statements are reclassified when necessary to conform to the current periods’ presentation. Information for the third quarter, second quarter, and first quarter of 2016 has been revised to reflect the impact of the adoption of ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting", in the fourth quarter of 2016, retroactive to January 1, 2016. All significant intercompany balances and transactions are eliminated in consolidation.

Accounting Standards Updates

Accounting Policies [Abstract]
Accounting Standards Updates	Accounting Standards Updates ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for us on January 1, 2017; however, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) - Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to January 1, 2018. The majority of Tompkins’ revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09. With respect to noninterest income, the Company has identified revenue streams within the scope of the guidance, and is performing an evaluation of the underlying revenue contracts potentially affected by this guidance, including insurance commissions and fees, trust and wealth management fees, deposit related fees, and interchange fees. While Tompkins does not expect these changes to have a significant impact on the Company’s consolidated financial statements, Tompkins is still in the process of completing its review. The Company expects that this standard will require enhanced monitoring and tracking of affected contracts. The Company plans to adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant. ASU 2016-01, “ Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ” ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale. ASU 2016-01 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our consolidated financial statements. ASU 2016-02,“Leases (Topic 842).” ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-2 will be effective for Tompkins on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company occupies certain banking offices and uses certain equipment under noncancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. Tompkins is preparing an inventory of its leases and evaluating the impact of this ASU on these leases. Upon adoption of the guidance, the Company expects to report increased assets and increased liabilities as a result of recognizing right-of-use assets and lease liabilities on its consolidated statement of condition. Tompkins is currently evaluating the extent of the impact that the adoption of this ASU will have on our consolidated financial statements. ASU 2016-05“Derivatives and Hedging (Topic 815) Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.” ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under ASC Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-05 became effective for Tompkins on January 1, 2017 and did not have a significant impact on our consolidated financial statements. ASU 2016-07, “Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” The amendments affect all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. ASU 2016-07 simplifies the transition to the equity method of accounting by eliminating retroactive adjustment of the investment when an investment qualifies for use of the equity method, among other things. ASU 2016-07 became effective for Tompkins on January 1, 2017 and did not have a significant impact on our consolidated financial statements. ASU 2016-08 , “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 was issued to clarify certain principal versus agent considerations within the implementation guidance of ASC Topic 606, “ Revenue from Contracts with Customers .” The effective date and transition of ASU 2016-08 is the same as the effective date and transition of ASU 2014-09, " Revenue from Contracts with Customers (Topic 606) ," as discussed above. Tompkins is currently evaluating the potential impact of ASU 2016-08 on our consolidated financial statements. ASU No. 2016-10 , “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 was issued to clarify ASC Topic 606, “Revenue from Contracts with Customers” related to (i) identifying performance obligations; and (ii) the licensing implementation guidance. The effective date and transition of ASU 2016-10 is the same as the effective date and transition of ASU 2014-09 , “Revenue from Contracts with Customers (Topic 606),” as discussed above. Tompkins is currently evaluating the potential impact of ASU 2016-10 on our consolidated financial statements. ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. Tompkins is currently evaluating the requirements of the new guidance to determine what modifications to our existing allowance methodology may be required. The Company expects that the new guidance will likely result in an increase in the allowance; however, Tompkins is unable to quantify the impact at this time since we are still reviewing the guidance. The extent of any impact to our allowance will depend, in part, upon the composition of our loan portfolio at the adoption date as well as economic conditions and loss forecasts at that date. ASU 2016-15, “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. ASU 2016-15 will be effective for us on January 1, 2018. Tompkins is currently evaluating the potential impact of ASU 2016-15 on our consolidated financial statements. ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for us on January 1, 2020, with early adoption permitted for interim or annual impairment tests beginning in 2017. Tompkins is currently evaluating the potential impact of ASU 2017-04 on our consolidated financial statements. ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. ASU 2017-05 reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. ASU 2017-05 will be effective for us on January 1, 2018. Tompkins is currently evaluating the potential impact of ASU 2017-05 on our consolidated financial statements. ASU 2017-07, “Compensation-Retirement Benefits (Topic 715 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.”), which requires that the service cost component of the Company's net periodic pension cost and net periodic postretirement benefit cost be included in the same line item as other compensation costs arising from services rendered by employees, with the other components of net periodic benefit cost being classified outside of a subtotal of income from operations. Of the components of net periodic benefit cost, only the service cost component will be eligible for asset capitalization. ASU 2017-07 is effective for the Company beginning January 1, 2018 and is required to be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement. Tompkins is currently evaluating the potential impact of ASU 2017-07 on our consolidated financial statements. ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 will be effective for us on January 1, 2019, with early adoption permitted. Tompkins is currently evaluating the potential impact of ASU 2017-08 on our consolidated financial statements. ASU 2017-09 , “Compensation-Stock Compensation (Topic 718)- Scope of Modification Accounting.” ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award's fair value, (ii) the award's vesting conditions and (iii) the award's classification as an equity or liability instrument. ASU 2017-09 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our consolidated financial statements.

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 quality of the investment securities. The Company does not intend to sell other-than-temporarily impaired investment securities that are in an unrealized loss position until recovery of unrealized losses (which may be until maturity), and it is not more-likely-than not that the Company will be required to sell the investment securities, before recovery of their amortized cost basis, which may be at maturity. Accordingly, as of September 30, 2017 , and December 31, 2016 , management has determined that the unrealized losses detailed in the tables above are not other-than-temporary. Ongoing Assessment of Other-Than-Temporary Impairment On a quarterly basis, the Company performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment (“OTTI”). A debt security is considered impaired if the fair value is less than its amortized cost basis (including any previous OTTI charges) at the reporting date. If impaired, the Company then assesses whether the unrealized loss is other-than-temporary. An unrealized loss on a debt security is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value, discounted at the security’s effective rate, of the expected future cash flows is less than the amortized cost basis of the debt security. As a result, the credit loss component of an other-than-temporary impairment write-down for debt securities is recorded in earnings while the remaining portion of the impairment loss is recognized, net of tax, in other comprehensive income provided that the Company does not intend to sell the underlying debt security and it is more-likely-than not that the Company would not have to sell the debt security prior to recovery of the unrealized loss, which may be to maturity. If the Company intended to sell any securities with an unrealized loss or it is more-likely-than not that the Company would be required to sell the investment securities, before recovery of their amortized cost basis, then the entire unrealized loss would be recorded in earnings. The Company considers the following factors in determining whether a credit loss exists. • The length of time and the extent to which the fair value has been less than the amortized cost basis; • The level of credit enhancement provided by the structure which includes, but is not limited to, credit subordination positions, excess spreads, overcollateralization, protective triggers; • Changes in the near term prospects of the issuer or underlying collateral of a security, such as changes in default rates, loss severities given default and significant changes in prepayment assumptions; • The level of excess cash flow generated from the underlying collateral supporting the principal and interest payments of the debt securities; and • Any adverse change to the credit conditions of the issuer or the security such as credit downgrades by the rating agencies. As a result of the other-than-temporarily impairment review process, the Company does not consider any investment security held at September 30, 2017 to be other-than-temporarily impaired. 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, FHLBPITT stock, and ACBB stock totaled $26.6 million , $13.6 million and $95,000 at September 30, 2017 , respectively. These securities are carried at par, which is also cost. The FHLBNY and FHLBPITT continue 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 September 30, 2017 , we have determined that no impairment write-downs are currently 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, 2016 . 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 September 30, 2017 . 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 contractually 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. Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing after the date of acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, we may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount. To the extent we cannot reasonably estimate cash flows, interest income recognition is discontinued. The Company has determined that it can reasonably estimate future cash flows on our acquired loans that are past due 90 days or more and accruing interest and the Company expects to fully collect the carrying value of the loans.

Receivables [Abstract]
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses Originated Loans and Leases Management reviews the appropriateness of the allowance for loan and lease losses (“allowance”) 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 loan 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. 102, Selected Loan Loss Allowance Methodology and Documentation Issues and ASC Topic 310, Receivables and ASC Topic 450, Contingencies . The model is comprised of four major components that management has deemed appropriate in evaluating the appropriateness of the allowance for loan and lease losses. While none of these components, when used independently, is effective in arriving at a reserve level that appropriately measures the risk inherent in the portfolio, management believes that using them collectively, provides reasonable measurement of the loss exposure in the portfolio. The four components include: impaired loans; individually reviewed and graded loans; historical loss experience; and qualitative or subjective analysis. Since the methodology is based upon historical experience and trends as well as management’s judgment, factors may arise that result in different estimates. Significant factors that could give rise to changes in these estimates may include, but are not limited to, changes in economic conditions in the local area, concentration of risk, changes in interest rates, and declines in local property values. While management’s evaluation of the allowance as of September 30, 2017 , considers the allowance to be appropriate, under adversely different conditions or assumptions, the Company would need to increase or decrease the allowance. Acquired Loans and Leases Acquired loans accounted for under ASC 310-30 For our acquired loans, our allowance for loan losses is estimated based upon our expected cash flows for these loans. To the extent that we experience 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. Acquired loans accounted for under ASC 310-20 We establish our allowance for loan losses through a provision for credit losses based upon an evaluation process that is similar to our evaluation process used for originated loans. This evaluation, which includes a review of loans on which full collectability may not be reasonably assured, considers, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan loss experience, carrying value of the loans, which includes the remaining net purchase discount or premium, and other factors that warrant recognition in determining our allowance for loan losses. The following tables detail activity in the allowance for loan and lease losses segregated by originated and acquired loan and lease portfolios and by portfolio segment for the three and nine months ended September 30, 2017 and 2016 . Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

$ 0 $ 394,111 A loan is impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans consist of our non-homogenous nonaccrual loans, and all loans restructured in a troubled debt restructuring (TDR). Specific reserves on individually identified impaired loans that are not collateral dependent are measured based on the present value of expected future cash flows discounted at the original effective interest rate of each loan. For loans that are collateral dependent, impairment is measured based on the fair value of the collateral less estimated selling costs, and such impaired amounts are generally charged off. The majority of impaired loans are collateral dependent impaired loans that have limited exposure or require limited specific reserves because of the amount of collateral support with respect to these loans, and previous charge-offs. Interest payments on impaired loans are typically applied to principal unless collectibility of the principal amount is reasonably assured. In these cases, interest is recognized on a cash basis.

FDIC Indemnification Asset Related to Covered Loans	FDIC Indemnification Asset Related to Covered Loans Prior to the third quarter of 2016, the Company had certain loans acquired in the VIST Financial acquisition which were covered loans with loss share agreements with the FDIC. Based on an analysis of outstanding loans covered under the one remaining loss share agreement, management decided to early terminate its one remaining loss share agreement with the FDIC during the third quarter of 2016. At that time the Company recorded pre-tax expense of $313,000 to terminate the agreement and write-off the remaining book value of the FDIC indemnification asset, which included $174,000 in expense for early termination and $139,000 to write off the remaining asset. The remaining balances of the loans previously reported as Covered Loans are included in the acquired loan balances by loan type subsequent to termination.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per share in the table below, for the three and nine month periods ended September 30, 2017 and 2016 are calculated under the two-class method as required by ASC Topic 260, Earnings Per Share. 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. The Company has issued restricted stock awards that contain such rights and are therefore 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.

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 September 30, 2017 , the Company’s maximum potential obligation under standby letters of credit was $29.7 million compared to $57.7 million at December 31, 2016 . 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	Fair Value FASB ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles 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). 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 FASB ASC Topic 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 table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016 , segregated by the level of valuation inputs within the fair value hierarchy used to measure fair value.

There were no transfers between Levels 1, 2 and 3 for the nine months ended September 30, 2017 . The Company determines fair value for its trading securities using independently quoted market prices. The Company determines fair value for its available-for-sale securities using an independent bond pricing service for identical assets or very similar securities. The Company has reviewed the pricing sources, including methodologies used, and finds them to be fairly stated. Certain assets are measured at fair value on a nonrecurring basis. For the Company, these include loans held for sale, collateral dependent impaired loans, and other real estate owned (“OREO”). During the third quarter and first nine months of 2017, certain collateral dependent impaired loans were remeasured and reported at fair value through a specific valuation allowance and/or partial charge-offs for loan and lease losses based upon the fair value of the underlying collateral. Collateral values are estimated using Level 2 inputs based upon observable market data. In addition to collateral dependent impaired loans, certain other real estate owned were 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 on other real estate owned are taken through a charge-off to the allowance for loan and lease losses. Subsequent fair value write-downs on other real estate owned are reported in other noninterest expense.

The carrying amounts shown in the table are included in the Consolidated Statements of Condition under the indicated captions. The fair value estimates, methods and assumptions set forth below for the Company’s financial instruments, including those financial instruments carried at cost, are made solely to comply with disclosures required by generally accepted accounting principles in the United States and do not always incorporate the exit-price concept of fair value prescribed by ASC Topic 820-10 and should be read in conjunction with the financial statements and notes included in this Report.

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: 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 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. Loans and Leases: The fair values of residential loans are estimated using discounted cash flow analyses, based upon available market benchmarks for rates and prepayment assumptions. The fair values of commercial and consumer loans are estimated using discounted cash flow analyses, based upon interest rates currently offered for loans and leases with similar terms and credit quality. The fair value of loans held for sale are determined based upon contractual prices for loans with similar characteristics. FHLB 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. 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. Securities Sold Under Agreements to Repurchase: The carrying amounts of repurchase agreements and other short-term borrowings approximate their fair values. Fair values of long-term borrowings are estimated using a discounted cash flow approach, based on current market rates for similar borrowings. For securities sold under agreements to repurchase where the Company has elected the fair value option, the Company also receives pricing information from third parties, including the FHLB. Other Borrowings: The fair values of other borrowings are estimated using discounted cash flow analysis, discounted at the Company’s current incremental borrowing rate for similar borrowing arrangements. For other borrowings where the Company has elected the fair value option, the Company also receives pricing information from third parties, including the FHLB. Trust Preferred Debentures: The fair value of the trust preferred debentures has been estimated using a discounted cash flow analysis which uses a discount factor of a market spread over current interest rates for similar instruments.

Accounting Standards Updates (P

Accounting Standards Updates (Policies)	9 Months Ended

Accounting Policies [Abstract]
Accounting Standards Updates	Accounting Standards Updates ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for us on January 1, 2017; however, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) - Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to January 1, 2018. The majority of Tompkins’ revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09. With respect to noninterest income, the Company has identified revenue streams within the scope of the guidance, and is performing an evaluation of the underlying revenue contracts potentially affected by this guidance, including insurance commissions and fees, trust and wealth management fees, deposit related fees, and interchange fees. While Tompkins does not expect these changes to have a significant impact on the Company’s consolidated financial statements, Tompkins is still in the process of completing its review. The Company expects that this standard will require enhanced monitoring and tracking of affected contracts. The Company plans to adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant. ASU 2016-01, “ Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ” ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale. ASU 2016-01 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our consolidated financial statements. ASU 2016-02,“Leases (Topic 842).” ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-2 will be effective for Tompkins on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company occupies certain banking offices and uses certain equipment under noncancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. Tompkins is preparing an inventory of its leases and evaluating the impact of this ASU on these leases. Upon adoption of the guidance, the Company expects to report increased assets and increased liabilities as a result of recognizing right-of-use assets and lease liabilities on its consolidated statement of condition. Tompkins is currently evaluating the extent of the impact that the adoption of this ASU will have on our consolidated financial statements. ASU 2016-05“Derivatives and Hedging (Topic 815) Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.” ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under ASC Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-05 became effective for Tompkins on January 1, 2017 and did not have a significant impact on our consolidated financial statements. ASU 2016-07, “Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” The amendments affect all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. ASU 2016-07 simplifies the transition to the equity method of accounting by eliminating retroactive adjustment of the investment when an investment qualifies for use of the equity method, among other things. ASU 2016-07 became effective for Tompkins on January 1, 2017 and did not have a significant impact on our consolidated financial statements. ASU 2016-08 , “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 was issued to clarify certain principal versus agent considerations within the implementation guidance of ASC Topic 606, “ Revenue from Contracts with Customers .” The effective date and transition of ASU 2016-08 is the same as the effective date and transition of ASU 2014-09, " Revenue from Contracts with Customers (Topic 606) ," as discussed above. Tompkins is currently evaluating the potential impact of ASU 2016-08 on our consolidated financial statements. ASU No. 2016-10 , “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 was issued to clarify ASC Topic 606, “Revenue from Contracts with Customers” related to (i) identifying performance obligations; and (ii) the licensing implementation guidance. The effective date and transition of ASU 2016-10 is the same as the effective date and transition of ASU 2014-09 , “Revenue from Contracts with Customers (Topic 606),” as discussed above. Tompkins is currently evaluating the potential impact of ASU 2016-10 on our consolidated financial statements. ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. Tompkins is currently evaluating the requirements of the new guidance to determine what modifications to our existing allowance methodology may be required. The Company expects that the new guidance will likely result in an increase in the allowance; however, Tompkins is unable to quantify the impact at this time since we are still reviewing the guidance. The extent of any impact to our allowance will depend, in part, upon the composition of our loan portfolio at the adoption date as well as economic conditions and loss forecasts at that date. ASU 2016-15, “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. ASU 2016-15 will be effective for us on January 1, 2018. Tompkins is currently evaluating the potential impact of ASU 2016-15 on our consolidated financial statements. ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for us on January 1, 2020, with early adoption permitted for interim or annual impairment tests beginning in 2017. Tompkins is currently evaluating the potential impact of ASU 2017-04 on our consolidated financial statements. ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. ASU 2017-05 reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. ASU 2017-05 will be effective for us on January 1, 2018. Tompkins is currently evaluating the potential impact of ASU 2017-05 on our consolidated financial statements. ASU 2017-07, “Compensation-Retirement Benefits (Topic 715 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.”), which requires that the service cost component of the Company's net periodic pension cost and net periodic postretirement benefit cost be included in the same line item as other compensation costs arising from services rendered by employees, with the other components of net periodic benefit cost being classified outside of a subtotal of income from operations. Of the components of net periodic benefit cost, only the service cost component will be eligible for asset capitalization. ASU 2017-07 is effective for the Company beginning January 1, 2018 and is required to be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement. Tompkins is currently evaluating the potential impact of ASU 2017-07 on our consolidated financial statements. ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 will be effective for us on January 1, 2019, with early adoption permitted. Tompkins is currently evaluating the potential impact of ASU 2017-08 on our consolidated financial statements. ASU 2017-09 , “Compensation-Stock Compensation (Topic 718)- Scope of Modification Accounting.” ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award's fair value, (ii) the award's vesting conditions and (iii) the award's classification as an equity or liability instrument. ASU 2017-09 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our consolidated 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 nine month periods ended September 30, 2017 and 2016 are calculated under the two-class method as required by ASC Topic 260, Earnings Per Share. 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. The Company has issued restricted stock awards that contain such rights and are therefore 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.
