Basis of Presentation [Abstract]
Basis of Presentation	(1) Basis of Presentation Within the accompanying unaudited consolidated statement of financial condition, and related notes to the consolidated financial statements, June 30, 2018 data was derived from the audited consolidated financial statements of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and Greene Risk Management, Inc., and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank and Greene Property Holdings, Ltd. The consolidated financial statements at and for the three months ended September 30, 2018 and 2017 are unaudited. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2018, such information and notes have not been duplicated herein. In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included. Amounts in the prior year’s consolidated financial statements have been reclassified whenever necessary to conform to the current year’s presentation. These reclassifications, if any, had no effect on net income or retained earnings as previously reported. All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three months ended September 30, 2018 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2019. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued. CRITICAL ACCOUNTING POLICIES Greene County Bancorp, Inc.’s critical accounting policies relate to the allowance for loan losses and the evaluation of securities for other-than-temporary impairment. The allowance for loan losses is based on management’s estimation of an amount that is intended to absorb losses in the existing portfolio. The allowance for loan losses is established through a provision for loan losses based on management’s evaluation of the risk inherent in the loan portfolio, the composition of the portfolio, specific impaired loans and current economic conditions. Such evaluation, which includes a review of all loans for which full collectability may not be reasonably assured, considers among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, historical loan loss experience, management’s estimate of probable credit losses and other factors that warrant recognition in providing for the allowance of loan losses. However, this evaluation involves a high degree of complexity and requires management to make subjective judgments that often require assumptions or estimates about highly uncertain matters. This critical accounting policy and its application are periodically reviewed with the Audit Committee and the Board of Directors. There have been no significant changes in the application of this critical accounting policy during the three months ended September 30, 2018. Securities are evaluated for other-than-temporary impairment by performing periodic reviews of individual securities in the investment portfolio. Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security, on which there is an unrealized loss, is impaired on an other-than-temporary basis. The Company considers many factors, including the severity and duration of the impairment; the intent and ability of the Company to hold the equity security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, the intent to sell the security, the likelihood to be required to sell the security before it recovers the entire amortized cost, external credit ratings and recent downgrades. The Company is required to record other-than-temporary impairment charges through earnings, if it has the intent to sell, or will more likely than not be required to sell an impaired debt security before a recovery of its amortized cost basis. In addition, the Company is required to record other-than-temporary impairment charges through earnings for the amount of credit losses, regardless of the intent or requirement to sell. Credit loss is measured as the difference between the present value of an impaired debt security’s cash flows and its amortized cost basis. Non-credit related write-downs to fair value must be recorded as decreases to accumulated other comprehensive income as long as the Company has no intent or requirement to sell an impaired security before a recovery of amortized cost basis.

Use of Estimates [Abstract]
Use of Estimates	(3) Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the assessment of other-than-temporary security impairment. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses (the “Allowance”) may be necessary, based on changes in economic conditions, asset quality or other factors. In addition, various regulatory authorities, as an integral part of their examination process, periodically review the Allowance. Such authorities may require the Company to recognize additions to the Allowance based on their judgments of information available to them at the time of their examination. Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security on which there is an unrealized loss is impaired on an other-than-temporary basis. The Company considers many factors including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, intent to sell the security, whether it is more likely than not we will be required to sell the security before recovery, whether loss is expected, external credit ratings and recent downgrades. Securities on which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value through earnings.

The principal factors considered are (1) the length of time and the extent to which the fair value has been less than the amortized cost basis, (2) the financial condition of the issuer (and guarantor, if any) and adverse conditions specifically related to the security, industry or geographic area, (3) failure of the issuer of the security to make scheduled interest or principal payments, (4) any changes to the rating of the security by a rating agency, and (5) the presence of credit enhancements, if any, including the guarantee of the federal government or any of its agencies. For debt securities, OTTI is considered to have occurred if (1) the Company intends to sell the security before recovery of its amortized cost basis, (2) it is more likely than not the Company will be required to sell the security before recovery of its amortized cost basis, or (3) if the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. In determining the present value of expected cash flows, the Company discounts the expected cash flows at the effective interest rate implicit in the security at the date of acquisition. In estimating cash flows expected to be collected, the Company uses available information with respect to security prepayment speeds, default rates and severity. In determining whether OTTI has occurred for equity securities, the Company considers the applicable factors described above and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. For debt securities, credit-related OTTI is recognized in earnings while noncredit related OTTI on securities not expected to be sold is recognized in other comprehensive income/loss (“OCI”). Credit-related OTTI is measured as the difference between the present value of an impaired security’s expected cash flows and its amortized cost basis. Noncredit-related OTTI is measured as the difference between the fair value of the security and its amortized cost less any credit-related losses recognized. For securities classified as held-to-maturity, the amount of OTTI recognized in OCI is accreted to the credit-adjusted expected cash flow amounts of the securities over future periods. Management evaluated securities considering the factors as outlined above, and based on this evaluation the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2018. Management believes that the reasons for the decline in fair value are due to interest rates, widening credit spreads and market illiquidity at the reporting date. There were no transfers of securities available-for-sale to held-to-maturity during the three months ended September 30, 2018 or 2017. During the three months ended September 30, 2018 and 2017, there were no sales of securities and no gains or losses were recognized. There was no other-than-temporary impairment loss recognized during the three months ended September 30, 2018 and 2017. The estimated fair values of debt securities at September 30, 2018, by contractual maturity are shown below. 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.

This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. Impairment of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following: its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position. After evaluating these considerations, Greene County Bancorp, Inc. concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no other-than-temporary impairment charge was recorded during the three months ended September 30, 2018 or 2017.

Loans and Allowance for Loan Losses [Abstract]
Loans and Allowance for Loan Losses	(5) Loans and Allowance for Loan Losses Loan segments and classes at September 30, 2018 and June 30, 2018 are summarized as follows: (In thousands) September 30, 2018 June 30, 2018 Residential real estate: Residential real estate $ 262,264 $ 255,848 Residential construction and land 9,803 9,951 Multi-family 21,076 14,961 Commercial real estate: Commercial real estate 289,425 283,935 Commercial construction 38,836 39,366 Consumer loan: Home equity 21,744 21,919 Consumer installment 5,217 5,017 Commercial loans 87,711 84,644 Total gross loans 736,076 715,641 Allowance for loan losses (12,308 ) (12,024 ) Deferred fees and costs 758 814 Loans receivable, net $ 724,526 $ 704,431 Management closely monitors the quality of the loan portfolio and has established a loan review process designed to help grade the quality and profitability of the Company’s loan portfolio. The credit quality grade helps management make a consistent assessment of each loan relationship’s credit risk. Consistent with regulatory guidelines, The Bank of Greene County provides for the classification of loans considered being of lesser quality. Such ratings coincide with the “Substandard,” “Doubtful” and “Loss” classifications used by federal regulators in their examination of financial institutions. Generally, an asset is considered Substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. Substandard assets include those characterized by the distinct possibility that the insured financial institution will sustain some loss if the deficiencies are not corrected. Assets classified as Doubtful have all the weaknesses inherent in assets classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Assets classified as Loss are those considered uncollectible and of such little value that their continuance as assets without the establishment of a full loss reserve and/or charge-off is not warranted. Assets that do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories but otherwise possess weaknesses are designated “Special Mention.” Management also maintains a listing of loans designated “Watch.” These loans represent borrowers with declining earnings, strained cash flow, increasing leverage and/or weakening market fundamentals that indicate above average risk. When The Bank of Greene County classifies problem assets as either Substandard or Doubtful, it generally establishes a specific valuation allowance or “loss reserve” in an amount deemed prudent by management. General allowances represent loss allowances that have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been allocated to particular loans. When The Bank of Greene County identifies problem loans as being impaired, it is required to evaluate whether the Bank will be able to collect all amounts due either through repayments or the liquidation of the underlying collateral. If it is determined that impairment exists, the Bank is required either to establish a specific allowance for losses equal to the amount of impairment of the assets, or to charge-off such amount. The Bank of Greene County’s determination as to the classification of its loans and the amount of its valuation allowance is subject to review by its regulatory agencies, which can order the establishment of additional general or specific loss allowances. The Bank of Greene County reviews its portfolio monthly to determine whether any assets require classification in accordance with applicable regulations. The Bank primarily has four segments within its loan portfolio that it considers when measuring credit quality: residential real estate loans, commercial real estate loans, consumer loans and commercial loans. The residential real estate portfolio consists of residential, construction, and multi-family loan classes. Commercial real estate loans consist of commercial real estate and commercial construction loan classes. Consumer loans consist of home equity loan and consumer installment loan classes. The inherent risk within the loan portfolio varies depending upon each of these loan types. The Bank of Greene County’s primary lending activity historically has been the origination of residential mortgage loans, including home equity loans, which are collateralized by residences. Generally, residential mortgage loans are made in amounts up to 89.9% of the appraised value of the property. However, The Bank of Greene County will originate residential mortgage loans with loan-to-value ratios of up to 95.0%, with private mortgage insurance. In the event of default by the borrower, The Bank of Greene County will acquire and liquidate the underlying collateral. By originating the loan at a loan-to-value ratio of 89.9% or less or obtaining private mortgage insurance, The Bank of Greene County limits its risk of loss in the event of default. However, the market values of the collateral may be adversely impacted by declines in the economy. Home equity loans may have an additional inherent risk if The Bank of Greene County does not hold the first mortgage. The Bank of Greene County may stand in a secondary position in the event of collateral liquidation resulting in a greater chance of insufficiency to meet all obligations. Construction lending generally involves a greater degree of risk than other residential mortgage lending. The repayment of the construction loan is, to a great degree, dependent upon the successful and timely completion of the construction of the subject property within specified cost limits. The Bank of Greene County completes inspections during the construction phase prior to any disbursements. The Bank of Greene County limits its risk during the construction as disbursements are not made until the required work for each advance has been completed. Construction delays may further impair the borrower’s ability to repay the loan. Loans collateralized by commercial real estate, and multi-family dwellings, such as apartment buildings generally are larger than residential loans and involve a greater degree of risk. Commercial real estate loans often involve large loan balances to single borrowers or groups of related borrowers. Payments on these loans depend to a large degree on the results of operations and management of the properties or underlying businesses, and may be affected to a greater extent by adverse conditions in the real estate market or the economy in general. Accordingly, the nature of commercial real estate loans makes them more difficult for management to monitor and evaluate. Consumer loans generally have shorter terms and higher interest rates than residential mortgage loans. In addition, consumer loans expand the products and services offered by The Bank of Greene County to better meet the financial services needs of its customers. Consumer loans generally involve greater credit risk than residential mortgage loans because of the difference in the nature of the underlying collateral. Repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance because of the greater likelihood of damage, loss or depreciation in the underlying collateral. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections depend on the borrower’s personal financial stability. Furthermore, the application of various federal and state laws, including federal and state bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans. Commercial lending generally involves greater risk than residential mortgage lending and involves risks that are different from those associated with residential and commercial real estate mortgage lending. Real estate lending is generally considered to be collateral-based, with loan amounts based on fixed loan-to-collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default. Although commercial loans may be collateralized by equipment or other business assets, the liquidation of collateral in the event of a borrower default is often an insufficient source of repayment because equipment and other business assets may be obsolete or of limited use, among other things. Accordingly, the repayment of a commercial loan depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. Over the past few years, The Bank of Greene County has shifted more focus on the origination of commercial loans including commercial real estate. The Bank of Greene County has also formed relationships with other community banks within our region to participate in larger commercial loan relationships. These types of loans are generally considered to be riskier due to the size and complexity of the loan relationship. By entering into a participation agreement with the other bank, The Bank of Greene County can obtain the loan relationship while limiting its exposure to credit loss. Management completes its due diligence in underwriting these loans and monitors the servicing of these loans. Loan balances by internal credit quality indicator at September 30, 2018 are shown below.

Nonaccrual Loans Management places loans on nonaccrual status once the loans have become 90 days or more delinquent. A nonaccrual loan is defined as a loan in which collectability is questionable and therefore interest on the loan will no longer be recognized on an accrual basis. A loan is not placed back on accrual status until the borrower has demonstrated the ability and willingness to make timely payments on the loan. A loan does not have to be 90 days delinquent in order to be classified as nonaccrual. Nonaccrual loans consisted primarily of loans secured by real estate at September 30, 2018 and June 30, 2018. Loans on nonaccrual status totaled $3.4 million at September 30, 2018 of which $1.8 million were in the process of foreclosure. At September 30, 2018, there were 10 residential loans in the process of foreclosure totaling $1.2 million. Included in nonaccrual loans were $1.6 The following table sets forth information regarding delinquent and/or nonaccrual loans at September 30, 2018: (In thousands) 30-59 days past due 60-89 days past due 90 days or more past due Total past due Current Total Loans Loans on Non-accrual Residential real estate $ 3,140 $ 337 $ 823 $ 4,300 $ 257,964 $ 262,264 $ 1,634 Residential construction and land - - - - 9,803 9,803 - Multi-family 141 - - 141 20,935 21,076 - Commercial real estate 1,150 481 568 2,199 287,226 289,425 1,119 Commercial construction - - - - 38,836 38,836 - Home equity 179 - 408 587 21,157 21,744 529 Consumer installment 19 13 8 40 5,177 5,217 17 Commercial loans 433 103 - 536 87,175 87,711 88 Total gross loans $ 5,062 $ 934 $ 1,807 $ 7,803 $ 728,273 $ 736,076 $ 3,387 The following table sets forth information regarding delinquent and/or nonaccrual loans at June 30, 2018: (In thousands) 30-59 days past due 60-89 days past due 90 days or more past due Total past due Current Total Loans Loans on Non-accrual Residential real estate $ 1,617 $ 458 $ 1,211 $ 3,286 $ 252,562 $ 255,848 $ 1,778 Residential construction and land - - - - 9,951 9,951 - Multi-family - - - - 14,961 14,961 - Commercial real estate 1,568 487 568 2,623 281,312 283,935 1,147 Commercial construction - - - - 39,366 39,366 - Home equity 38 128 299 465 21,454 21,919 298 Consumer installment 3 30 8 41 4,976 5,017 18 Commercial loans 250 195 182 627 84,017 84,644 276 Total gross loans $ 3,476 $ 1,298 $ 2,268 $ 7,042 $ 708,599 $ 715,641 $ 3,517 The Bank of Greene County had no accruing loans delinquent more than 90 days at September 30, 2018 and $62,000 at June 30, 2018, respectively. The loans delinquent more than 90 days and accruing consist of loans that are well collateralized and the borrowers have demonstrated the ability and willingness to pay. The borrower has made arrangements with the Bank to bring the loan current within a specified time period and has made a series of payments as agreed.

Allowance for Loan Losses The allowance for loan losses is established through a provision for loan losses based on management’s evaluation of the risk inherent in the loan portfolio, the composition of the loan portfolio, specific impaired loans and current economic conditions. Such evaluation, which includes a review of certain identified loans on which full collectability may not be reasonably assured, considers among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, payment status of the loan, historical loan loss experience and other factors that warrant recognition in providing for the loan loss allowance. In addition, various regulatory agencies, as an integral part of their examination process, periodically review The Bank of Greene County’s allowance for loan losses. Such agencies may require The Bank of Greene County to recognize additions to the allowance based on their judgment about information available to them at the time of their examination. The Bank of Greene County considers smaller balance residential mortgages, home equity loans, commercial loans and installment loans to customers as small, homogeneous loans, which are evaluated for impairment collectively based on historical loss experience. Larger balance residential, commercial mortgage and business loans are viewed individually and considered impaired if it is probable that The Bank of Greene County will not be able to collect scheduled payments of principal and interest when due, according to the contractual terms of the loan agreements. The measurement of impaired loans is generally based on the fair value of the underlying collateral. The Bank of Greene County charges loans off against the allowance for credit losses when it becomes evident that a loan cannot be collected within a reasonable amount of time or that it will cost the Bank more than it will receive, and all possible avenues of repayment have been analyzed, including the potential of future cash flow, the value of the underlying collateral, and strength of any guarantors or co-borrowers. Generally, consumer loans and smaller business loans (not secured by real estate) in excess of 90 days are charged-off against the allowance for loan losses, unless equitable arrangements are made. For loans secured by real estate, a charge-off is recorded when it is determined that the collection of all or a portion of a loan may not be collected and the amount of that loss can be reasonably estimated.

Fair Value Measurements and Fair Value of Financial Instruments [Abstract]
Fair Value Measurements and Fair Value of Financial Instruments	(6) Fair Value Measurements and Fair Value of Financial Instruments Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sale transaction on the dates indicated. The estimated fair value amounts have been measured at September 30, 2018 and June 30, 2018 and have not been re-evaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. The FASB ASC Topic on “ Fair Value Measurement” 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 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 with little or no market activity). An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. For assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used are as follows: Fair Value Measurements Using Quoted Prices In Active Markets Significant Other Observable Significant Unobservable Inputs (In thousands) September 30, 2018 (Level 1) (Level 2) (Level 3) Assets: U.S. Government sponsored enterprises $ 5,496 $ - $ 5,496 $ - State and political subdivisions 92,320 - 92,320 - Mortgage-backed securities-residential 2,985 - 2,985 - Mortgage-backed securities-multi-family 17,095 - 17,095 - Corporate debt securities 1,704 1,704 - - Securities available-for-sale 119,600 1,704 117,896 - Equity securities 232 232 - - Total securities measured at fair value $ 119,832 $ 1,936 $ 117,896 $ - Fair Value Measurements Using Quoted Prices In Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (In thousands) June 30, 2018 (Level 1) (Level 2) (Level 3) Assets: U.S. Government sponsored enterprises $ 5,531 $ - $ 5,531 $ - State and political subdivisions 92,255 - 92,255 - Mortgage-backed securities-residential 3,247 - 3,247 - Mortgage-backed securities-multi-family 18,069 - 18,069 - Corporate debt securities 1,704 1,704 - - Securities available-for-sale $ 120,806 $ 1,704 $ 119,102 $ - Equity securities 217 217 - - Total securities measured at fair value $ 121,023 $ 1,921 $ 119,102 $ - Certain investments that are actively traded and have quoted market prices have been classified as Level 1 valuations. Other available-for-sale investment securities have been valued by reference to prices for similar securities or through model-based techniques in which all significant inputs are observable and, therefore, such valuations have been classified as Level 2. In addition to disclosures of the fair value of assets on a recurring basis, FASB ASC Topic on “ Fair Value Measurement” Receivables –Loan Impairment” Fair values for foreclosed real estate are initially recorded based on market value evaluations by third parties, less costs to sell (“initial cost basis”). Any write-downs required when the related loan receivable is exchanged for the underlying real estate collateral at the time of transfer to foreclosed real estate are charged to the allowance for loan losses. Values are derived from appraisals, similar to impaired loans, of underlying collateral or discounted cash flow analysis. Subsequent to foreclosure, valuations are updated periodically and assets are marked to current fair value, not to exceed the initial cost basis. In the determination of fair value subsequent to foreclosure, management also considers other factors or recent developments, such as, changes in absorption rates and market conditions from the time of valuation and anticipated sales values considering management’s plans for disposition. Either change could result in adjustment to lower the property value estimates indicated in the appraisals. These measurements are classified as Level 3 within the fair value hierarchy.

(2) Appraisals may be adjusted downwards by management for qualitative factors such as economic conditions. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received or age of the appraisal. (3) Appraisals are adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral. The carrying amounts reported in the statements of financial condition for cash and cash equivalents, accrued interest receivable and accrued interest payable approximate their fair values. Fair values of securities are based on quoted market prices (Level 1), where available, or matrix pricing (Level 2), which is a mathematical technique, used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. The carrying amount of Federal Home Loan Bank stock approximates fair value due to its restricted nature. ASU 2016-01 "Recognition and Measurement of Financial Assets and Financial Liabilities" requires that, effective for the quarter ended September 30, 2018 the fair value for loans must be disclosed using the "exit price" notion which is a reasonable estimate of what another party might pay in an orderly transaction. Fair values for variable rate loans that reprice frequently, with no significant credit risk, are based on carrying value. Fair value for fixed rate loans are estimated using discounted cash flows and interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values disclosed for demand and savings deposits are equal to carrying amounts at the reporting date. The carrying amounts for variable rate money market deposits approximate fair values at the reporting date. Fair values for fixed rate certificates of deposit are estimated using discounted cash flows and interest rates currently being offered in the market on similar certificates. Fair value for Federal Home Loan Bank long term borrowings are estimated using discounted cash flows and interest rates currently being offered on similar borrowings. The carrying value of short-term Federal Home Loan Bank borrowings approximates its fair value. The fair value of commitments to extend credit is estimated based on an analysis of the interest rates and fees currently charged to enter into similar transactions, considering the remaining terms of the commitments and the credit-worthiness of the potential borrowers. At September 30, 2018 and June 30, 2018, the estimated fair values of these off-balance sheet financial instruments were immaterial, and are therefore excluded from the table below. The carrying amounts and estimated fair value of financial instruments are as follows: (In thousands) September 30, 2018 Fair Value Measurements Using Carrying Amount Fair Value (Level 1) (Level 2) (Level 3) Cash and cash equivalents $ 35,132 $ 35,132 $ 35,132 $ - $ - Long term certificate of deposit 2,385 2,385 2,385 - - Securities available-for-sale 119,600 119,600 1,704 117,896 - Securities held-to-maturity 280,774 279,061 - 279,061 - Equity securities 232 232 232 - Federal Home Loan Bank stock 4,147 4,147 - 4,147 - Net loans 724,526 708,759 - - 708,759 Accrued interest receivable 5,437 5,437 - 5,437 - Deposits 1,002,461 1,002,468 - 1,002,468 - Borrowings 75,950 75,604 - 75,604 - Accrued interest payable 96 96 - 96 - (In thousands) June 30, 2018 Fair Value Measurements Using Carrying Amount Fair Value (Level 1) (Level 2) (Level 3) Cash and cash equivalents $ 26,504 $ 26,504 $ 26,504 $ - $ - Long term certificate of deposit 2,385 2,385 2,385 - - Securities available-for-sale 120,806 120,806 1,704 119,102 - Securities held-to-maturity 274,550 274,177 - 274,177 - Equity securities 217 217 217 - - Federal Home Loan Bank stock 1,545 1,545 - 1,545 - Net loans 704,431 698,879 - - 698,879 Accrued interest receivable 5,057 5,057 - 5,057 - Deposits 1,025,234 1,025,302 - 1,025,302 - Borrowings 18,150 17,755 - 17,755 - Accrued interest payable 88 88 - 88 -

Earnings Per Share [Abstract]
Earnings Per Share	(7) Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed in a manner similar to that of basic earnings per share except that the weighted-average number of common shares outstanding is increased to include the number of incremental common shares that would have been outstanding under the treasury stock method if all potentially dilutive common shares (such as stock options) issued became vested during the period. There were no anti-dilutive securities or contracts outstanding during the three months ended September 30, 2018 and 2017. For the three months ended September 30, 2018 2017 Net Income $ 4,380 ,000 $ 3,472,000 Weighted Average Shares – Basic 8,537,814 8,502,734 Effect of Dilutive Stock Options - 28,508 Weighted Average Shares - Dilute 8,537,814 8,531,242 Earnings per share - Basic $ 0.51 $ 0.41 Earnings per share - Diluted $ 0.51 $ 0.41

Impact of Recent Accounting Pronouncements [Abstract]
Impact of Recent Accounting Pronouncements	(9) Impact of Recent Accounting Pronouncements Accounting Pronouncements Recently Adopted The following accounting standards have been adopted in the first quarter ended September 30, 2018: On July 1, 2018, Greene County Bancorp, Inc. adopted Accounting Standard Update (“ASU”) 2014-09 amending guidance on “Revenue from Contracts with Customers (Topic 606)”. The objective of the ASU is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. This ASU replaces most existing revenue recognition guidance under GAAP. A significant amount of the Company’s revenues are derived from net interest income on financial assets and liabilities, which are excluded from the scope of the amended guidance. With respect to noninterest income, the Company has identified revenue streams within the scope of the guidance, which include service charges on deposits, interchange income, investment services fees and gains (losses) from the transfer of other real estate owned. Further details regarding the revenue recognition of these revenue streams is provided in Note 13 to these Unaudited Consolidated Financial Statements. On July 1, 2018, Greene County Bancorp, Inc. adopted ASU 2016-01 amending guidance on “Financial Instruments (Subtopic 825-10)”. This amendment addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. These amendments require equity securities to be measured at fair value with changes in the fair value to be recognized through net income. The amendments also simplify the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. As of June 30, 2018, the Company had several small equity investments with a cost of $62,000 and a fair value of $217,000. On July 1, 2018, the Company recorded a cumulative-effect adjustment to increase retained earnings in the amount of $114,000 representing the unrealized gain, net of tax, on these equity securities. Changes in fair value during the three-months ended September 30, 2018 have been recognized in net income. ASU 2016-01 also emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities not make use of a practicability exception in determining the fair value of loans. Accordingly, we refined the calculation used to determine the disclosed fair value of our loans as part of adopting this standard. See Note 6. Fair Value Measurements and Fair Value of Financial Instruments for further information. On July 1, 2018, Greene County Bancorp, Inc. adopted ASU 2017-07 amending guidance on “Compensation - Retirement Benefits (Topic 715)” to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. ASU 2017-07 requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. Prior to adoption of this update, the Company presented all components of net periodic pension cost in “salaries and employee benefits” on its income statement. The Company is presenting all components of net period pension cost in “other expense” for the three-months ended September 30, 2018 and 2017, as the Company’s defined pension plan does not have a service cost component since the plan was frozen in 2006. Further details regarding the Company’s net periodic pension cost are provided in Note 10 to these Unaudited Consolidated Financial Statements. In August 2014, the FASB issued an amendment (ASU 2014-14) to its guidance on “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. The objective of the ASU is to reduce the diversity in how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure, to provide more decision-useful information about a creditor’s foreclosed mortgage loans that are expected to be recovered, at least in part, through government guarantees. The adoption of this guidance had no impact on our consolidated results of operations or financial position. In August 2016, the FASB issued an Update (ASU 2016-15) which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are intended to reduce diversity in practice. The amendment covers the following cash flows: Cash payments for debt prepayment or extinguishment costs will be classified in financing activities. Upon settlement of zero-coupon bonds and bonds with insignificant cash coupons, the portion of the payment attributable to imputed interest will be classified as an operating activity, while the portion of the payment attributable to principal will be classified as a financing activity. Cash paid by an acquirer that isn’t soon after a business combination for the settlement of a contingent consideration liability will be separated between financing activities and operating activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date will be classified in financing activities; any excess will be classified in operating activities. Cash paid soon after the business combination will be classified in investing activities. Cash proceeds received from the settlement of insurance claims will be classified on the basis of the related insurance coverage (that is, the nature of the loss). Cash proceeds from lump-sum settlements will be classified based on the nature of each loss included in the settlement. Cash proceeds received from the settlement of corporate-owned life insurance (COLI) and bank-owned life insurance (BOLI) policies will be classified as cash inflows from investing activities. Cash payments for premiums on COLI and BOLI may be classified as cash outflows for investing, operating, or a combination of both. A transferor’s beneficial interest obtained in a securitization of financial assets will be disclosed as a noncash activity, and cash received from beneficial interests will be classified in investing activities. Distributions received from equity method investees will be classified using either a cumulative earnings approach or a look- through approach as an accounting policy election. The ASU contains additional guidance clarifying when an entity should separate cash receipts and cash payments and classify them into more than one class of cash flows (including when reasonable judgment is required to estimate and allocate cash flows) versus when an entity should classify the aggregate amount into one class of cash flows on the basis of predominance. The adoption of this guidance had no impact on our consolidated results of operations or financial position. In November 2016, the FASB issued an Update (ASU 2016-18) to its guidance on “Statement of Cash Flows (Topic 230) Restricted Cash” addresses diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing or financing activities or as a combination of those activities in the statement of cash flows. The ASU requires entities to show the changes in the total cash, cash equivalents, restricted cash and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories will no longer be presented in the Statement of Cash Flows. The adoption of this guidance had no impact on our consolidated results of operations or financial position. In May 2017, the FASB issued an Update (ASU 2017-09) to its guidance on “Compensation - Stock Compensation (Topic 718)” such that an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award unless all of the following criteria are met: (1) The fair value of the modified award is the same as the fair value of the original award immediately before the modification. The standard indicates that if the modification does not affect any of the inputs to the valuation technique used to value the award, the entity is not required to estimate the value immediately before and after the modification. (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification. (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The adoption of this guidance had no impact on our consolidated results of operations or financial position. Accounting Pronouncements to be adopted in future periods In February 2016, the FASB issued an Update (ASU 2016-02) to its guidance on “Leases (Topic 842)”. The new leases standard applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this ASU will result in a gross up of the Consolidated Statements of Financial Condition for right-of-use assets and associated lease liabilities for operating leases in which the Company is the lessee. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations. Branch building leases have been reviewed and are considered immaterial to the financial statements; there are no equipment leases to consider. In June 2016, the FASB issued an Update (ASU 2016-13) to its guidance on “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”), should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance for credit losses is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for available-for-sale (AFS) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Company is currently evaluating the potential impact on our consolidated results of operations or financial position. The initial adjustment will not be reported in earnings and therefore will not have any material impact on our consolidated results of operations, but it is expected that it will have an impact on our consolidated financial position at the date of adoption of this Update. At this time, we have not calculated the estimated impact that this Update will have on our Allowance for Loan Losses, however, we anticipate it will have a significant impact on the methodology process we utilize to calculate the allowance. A vendor has been selected and alternative methodologies are currently being considered. Data requirements and integrity are being reviewed and enhancements incorporated into standard processes. The Company is in the early stages of evaluation and implementation of the guidance. In March 2017, the FASB issued an Update (ASU 2017-08) to its guidance on “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20) related to premium amortization on purchased callable debt securities. The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosure about a change in accounting principle. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In August 2018, the FASB issued an Update (ASU 2018-13) to its guidance on “Fair Value Measurement (Topic 820)”. This update modifies the disclosure requirements on fair value measurements. The following disclosure requirements were removed from Topic 820: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; (3) the valuation processes for Level 3 fair value measurements; and (4) for nonpublic entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The following disclosure requirements were modified in Topic 820: (1) in lieu of a rollforward for Level 3 fair value measurements, a nonpublic entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities; (2) for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and (3) the amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820; however, the disclosures are not required for nonpublic entities: (1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. In addition, the amendments eliminate at a minimum from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and to clarify that materiality is an appropriate consideration of entities and their auditors when evaluating disclosure requirements. The amendments in ASU No. 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until their effective date. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In August 2018, the FASB has issued an Update (ASU No. 2018-14), “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans”, that applies to all employers that sponsor defined benefit pension or other postretirement plans. The amendments modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The following disclosure requirements were removed from Subtopic 715-20: (1) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year; (2) the amount and timing of plan assets expected to be returned to the employer; (3) the disclosures related to the June 2001 amendments to the Japanese Welfare Pension Insurance Law; related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan; (4) for nonpublic entities, the reconciliation of the opening balances to the closing balances of plan assets measured on a recurring basis in Level 3 of the fair value hierarchy. However, nonpublic entities will be required to disclose separately the amounts of transfers into and out of Level 3 of the fair value hierarchy and purchases of Level 3 plan assets; and (5) for public entities, the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. The following disclosure requirements were added to Subtopic 715-20: (1) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates; and (2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: (1) the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets; and (2) the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position.

Basis of Presentation [Abstract]
Basis of Presentation	Within the accompanying unaudited consolidated statement of financial condition, and related notes to the consolidated financial statements, June 30, 2018 data was derived from the audited consolidated financial statements of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and Greene Risk Management, Inc., and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank and Greene Property Holdings, Ltd. The consolidated financial statements at and for the three months ended September 30, 2018 and 2017 are unaudited. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2018, such information and notes have not been duplicated herein. In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included. Amounts in the prior year’s consolidated financial statements have been reclassified whenever necessary to conform to the current year’s presentation. These reclassifications, if any, had no effect on net income or retained earnings as previously reported. All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three months ended September 30, 2018 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2019. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued. CRITICAL ACCOUNTING POLICIES Greene County Bancorp, Inc.’s critical accounting policies relate to the allowance for loan losses and the evaluation of securities for other-than-temporary impairment. The allowance for loan losses is based on management’s estimation of an amount that is intended to absorb losses in the existing portfolio. The allowance for loan losses is established through a provision for loan losses based on management’s evaluation of the risk inherent in the loan portfolio, the composition of the portfolio, specific impaired loans and current economic conditions. Such evaluation, which includes a review of all loans for which full collectability may not be reasonably assured, considers among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, historical loan loss experience, management’s estimate of probable credit losses and other factors that warrant recognition in providing for the allowance of loan losses. However, this evaluation involves a high degree of complexity and requires management to make subjective judgments that often require assumptions or estimates about highly uncertain matters. This critical accounting policy and its application are periodically reviewed with the Audit Committee and the Board of Directors. There have been no significant changes in the application of this critical accounting policy during the three months ended September 30, 2018. Securities are evaluated for other-than-temporary impairment by performing periodic reviews of individual securities in the investment portfolio. Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security, on which there is an unrealized loss, is impaired on an other-than-temporary basis. The Company considers many factors, including the severity and duration of the impairment; the intent and ability of the Company to hold the equity security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, the intent to sell the security, the likelihood to be required to sell the security before it recovers the entire amortized cost, external credit ratings and recent downgrades. The Company is required to record other-than-temporary impairment charges through earnings, if it has the intent to sell, or will more likely than not be required to sell an impaired debt security before a recovery of its amortized cost basis. In addition, the Company is required to record other-than-temporary impairment charges through earnings for the amount of credit losses, regardless of the intent or requirement to sell. Credit loss is measured as the difference between the present value of an impaired debt security’s cash flows and its amortized cost basis. Non-credit related write-downs to fair value must be recorded as decreases to accumulated other comprehensive income as long as the Company has no intent or requirement to sell an impaired security before a recovery of amortized cost basis.

Use of Estimates (Policies)

Use of Estimates (Policies)	3 Months Ended
	Sep. 30, 2018
Use of Estimates [Abstract]
Use of Estimates	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the assessment of other-than-temporary security impairment. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses (the “Allowance”) may be necessary, based on changes in economic conditions, asset quality or other factors. In addition, various regulatory authorities, as an integral part of their examination process, periodically review the Allowance. Such authorities may require the Company to recognize additions to the Allowance based on their judgments of information available to them at the time of their examination. Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security on which there is an unrealized loss is impaired on an other-than-temporary basis. The Company considers many factors including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, intent to sell the security, whether it is more likely than not we will be required to sell the security before recovery, whether loss is expected, external credit ratings and recent downgrades. Securities on which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value through earnings.

Securities (Policies)

Securities (Policies)	3 Months Ended

Securities [Abstract]
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. Impairment of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following: its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position. After evaluating these considerations, Greene County Bancorp, Inc. concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no other-than-temporary impairment charge was recorded during the three months ended September 30, 2018 or 2017.

Impact of Recent Accounting Pronouncements (Policies)	3 Months Ended

Impact of Recent Accounting Pronouncements [Abstract]
Impact of Recent Accounting Pronouncements	Accounting Pronouncements Recently Adopted The following accounting standards have been adopted in the first quarter ended September 30, 2018: On July 1, 2018, Greene County Bancorp, Inc. adopted Accounting Standard Update (“ASU”) 2014-09 amending guidance on “Revenue from Contracts with Customers (Topic 606)”. The objective of the ASU is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. This ASU replaces most existing revenue recognition guidance under GAAP. A significant amount of the Company’s revenues are derived from net interest income on financial assets and liabilities, which are excluded from the scope of the amended guidance. With respect to noninterest income, the Company has identified revenue streams within the scope of the guidance, which include service charges on deposits, interchange income, investment services fees and gains (losses) from the transfer of other real estate owned. Further details regarding the revenue recognition of these revenue streams is provided in Note 13 to these Unaudited Consolidated Financial Statements. On July 1, 2018, Greene County Bancorp, Inc. adopted ASU 2016-01 amending guidance on “Financial Instruments (Subtopic 825-10)”. This amendment addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. These amendments require equity securities to be measured at fair value with changes in the fair value to be recognized through net income. The amendments also simplify the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. As of June 30, 2018, the Company had several small equity investments with a cost of $62,000 and a fair value of $217,000. On July 1, 2018, the Company recorded a cumulative-effect adjustment to increase retained earnings in the amount of $114,000 representing the unrealized gain, net of tax, on these equity securities. Changes in fair value during the three-months ended September 30, 2018 have been recognized in net income. ASU 2016-01 also emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities not make use of a practicability exception in determining the fair value of loans. Accordingly, we refined the calculation used to determine the disclosed fair value of our loans as part of adopting this standard. See Note 6. Fair Value Measurements and Fair Value of Financial Instruments for further information. On July 1, 2018, Greene County Bancorp, Inc. adopted ASU 2017-07 amending guidance on “Compensation - Retirement Benefits (Topic 715)” to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. ASU 2017-07 requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. Prior to adoption of this update, the Company presented all components of net periodic pension cost in “salaries and employee benefits” on its income statement. The Company is presenting all components of net period pension cost in “other expense” for the three-months ended September 30, 2018 and 2017, as the Company’s defined pension plan does not have a service cost component since the plan was frozen in 2006. Further details regarding the Company’s net periodic pension cost are provided in Note 10 to these Unaudited Consolidated Financial Statements. In August 2014, the FASB issued an amendment (ASU 2014-14) to its guidance on “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. The objective of the ASU is to reduce the diversity in how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure, to provide more decision-useful information about a creditor’s foreclosed mortgage loans that are expected to be recovered, at least in part, through government guarantees. The adoption of this guidance had no impact on our consolidated results of operations or financial position. In August 2016, the FASB issued an Update (ASU 2016-15) which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are intended to reduce diversity in practice. The amendment covers the following cash flows: Cash payments for debt prepayment or extinguishment costs will be classified in financing activities. Upon settlement of zero-coupon bonds and bonds with insignificant cash coupons, the portion of the payment attributable to imputed interest will be classified as an operating activity, while the portion of the payment attributable to principal will be classified as a financing activity. Cash paid by an acquirer that isn’t soon after a business combination for the settlement of a contingent consideration liability will be separated between financing activities and operating activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date will be classified in financing activities; any excess will be classified in operating activities. Cash paid soon after the business combination will be classified in investing activities. Cash proceeds received from the settlement of insurance claims will be classified on the basis of the related insurance coverage (that is, the nature of the loss). Cash proceeds from lump-sum settlements will be classified based on the nature of each loss included in the settlement. Cash proceeds received from the settlement of corporate-owned life insurance (COLI) and bank-owned life insurance (BOLI) policies will be classified as cash inflows from investing activities. Cash payments for premiums on COLI and BOLI may be classified as cash outflows for investing, operating, or a combination of both. A transferor’s beneficial interest obtained in a securitization of financial assets will be disclosed as a noncash activity, and cash received from beneficial interests will be classified in investing activities. Distributions received from equity method investees will be classified using either a cumulative earnings approach or a look- through approach as an accounting policy election. The ASU contains additional guidance clarifying when an entity should separate cash receipts and cash payments and classify them into more than one class of cash flows (including when reasonable judgment is required to estimate and allocate cash flows) versus when an entity should classify the aggregate amount into one class of cash flows on the basis of predominance. The adoption of this guidance had no impact on our consolidated results of operations or financial position. In November 2016, the FASB issued an Update (ASU 2016-18) to its guidance on “Statement of Cash Flows (Topic 230) Restricted Cash” addresses diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing or financing activities or as a combination of those activities in the statement of cash flows. The ASU requires entities to show the changes in the total cash, cash equivalents, restricted cash and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories will no longer be presented in the Statement of Cash Flows. The adoption of this guidance had no impact on our consolidated results of operations or financial position. In May 2017, the FASB issued an Update (ASU 2017-09) to its guidance on “Compensation - Stock Compensation (Topic 718)” such that an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award unless all of the following criteria are met: (1) The fair value of the modified award is the same as the fair value of the original award immediately before the modification. The standard indicates that if the modification does not affect any of the inputs to the valuation technique used to value the award, the entity is not required to estimate the value immediately before and after the modification. (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification. (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The adoption of this guidance had no impact on our consolidated results of operations or financial position. Accounting Pronouncements to be adopted in future periods In February 2016, the FASB issued an Update (ASU 2016-02) to its guidance on “Leases (Topic 842)”. The new leases standard applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this ASU will result in a gross up of the Consolidated Statements of Financial Condition for right-of-use assets and associated lease liabilities for operating leases in which the Company is the lessee. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations. Branch building leases have been reviewed and are considered immaterial to the financial statements; there are no equipment leases to consider. In June 2016, the FASB issued an Update (ASU 2016-13) to its guidance on “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”), should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance for credit losses is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for available-for-sale (AFS) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Company is currently evaluating the potential impact on our consolidated results of operations or financial position. The initial adjustment will not be reported in earnings and therefore will not have any material impact on our consolidated results of operations, but it is expected that it will have an impact on our consolidated financial position at the date of adoption of this Update. At this time, we have not calculated the estimated impact that this Update will have on our Allowance for Loan Losses, however, we anticipate it will have a significant impact on the methodology process we utilize to calculate the allowance. A vendor has been selected and alternative methodologies are currently being considered. Data requirements and integrity are being reviewed and enhancements incorporated into standard processes. The Company is in the early stages of evaluation and implementation of the guidance. In March 2017, the FASB issued an Update (ASU 2017-08) to its guidance on “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20) related to premium amortization on purchased callable debt securities. The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosure about a change in accounting principle. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In August 2018, the FASB issued an Update (ASU 2018-13) to its guidance on “Fair Value Measurement (Topic 820)”. This update modifies the disclosure requirements on fair value measurements. The following disclosure requirements were removed from Topic 820: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; (3) the valuation processes for Level 3 fair value measurements; and (4) for nonpublic entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The following disclosure requirements were modified in Topic 820: (1) in lieu of a rollforward for Level 3 fair value measurements, a nonpublic entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities; (2) for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and (3) the amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820; however, the disclosures are not required for nonpublic entities: (1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. In addition, the amendments eliminate at a minimum from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and to clarify that materiality is an appropriate consideration of entities and their auditors when evaluating disclosure requirements. The amendments in ASU No. 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until their effective date. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In August 2018, the FASB has issued an Update (ASU No. 2018-14), “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans”, that applies to all employers that sponsor defined benefit pension or other postretirement plans. The amendments modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The following disclosure requirements were removed from Subtopic 715-20: (1) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year; (2) the amount and timing of plan assets expected to be returned to the employer; (3) the disclosures related to the June 2001 amendments to the Japanese Welfare Pension Insurance Law; related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan; (4) for nonpublic entities, the reconciliation of the opening balances to the closing balances of plan assets measured on a recurring basis in Level 3 of the fair value hierarchy. However, nonpublic entities will be required to disclose separately the amounts of transfers into and out of Level 3 of the fair value hierarchy and purchases of Level 3 plan assets; and (5) for public entities, the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. The following disclosure requirements were added to Subtopic 715-20: (1) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates; and (2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: (1) the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets; and (2) the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position.

[1]	Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable.
[2]	Appraisals may be adjusted downwards by management for qualitative factors such as economic conditions. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received or age of the appraisal.
[3]	Appraisals are adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral.
