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, 2020 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 and nine months ended March 31, 2021 and 2020 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, 2020, 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. The Company had no reclassifications from amounts in the prior year’s consolidated financial statements to conform to the current year’s presentation. All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three and nine months ended March 31, 2021 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2021. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued and should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K. 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 and nine months ended March 31, 2021, other than those implemented to respond to the coronavirus pandemic (“COVID-19”) as developed and initiated by governmental laws and programs as discussed throughout this document such as the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) including the Paycheck Protection Program (“PPP”) developed under this law. 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.

Nature of Operations

Nature of Operations	9 Months Ended
	Mar. 31, 2021
Nature of Operations [Abstract]
Nature of Operations	(2) Nature of Operations Greene County Bancorp, Inc.’s primary business is the ownership and operation of its subsidiaries, The Bank of Greene County and Greene Risk Management, Inc. The Bank of Greene County has 17 full-service offices and an operations center and lending center located in its market area within the Hudson Valley and Capital District Regions of New York State. The Bank of Greene County is primarily engaged in the business of attracting deposits from the general public in The Bank of Greene County’s market area, and investing such deposits, together with other sources of funds, in loans and investment securities. Greene Risk Management, Inc. is a pooled captive insurance company, which provides additional insurance coverage for the Company and its subsidiaries related to the operations of the Company for which insurance may not be economically feasible. The Bank of Greene County also owns and operates two subsidiaries, Greene County Commercial Bank and Greene Property Holdings, Ltd. Greene County Commercial Bank’s primary business is to attract deposits from, and provide banking services to, local municipalities. Greene Property Holdings, Ltd. was formed as a New York corporation that has elected under the Internal Revenue Code to be a real estate investment trust, which holds mortgages and notes which were originated through and serviced by The Bank of Greene County. During calendar year 2020, the world began and continues to respond to the pandemic. COVID-19 has caused business shutdowns or slowdowns, limitations on commercial activity, increased unemployment and commercial property vacancy rates, reduced profitability and ability for borrowers to make mortgage or other lending commitments. The overall economic and financial market instability has impacted households, individuals and businesses. The Company continues to closely monitor the impact of the pandemic on our business and results of operations. The Company recognizes and appreciates the staff who continue to assist retail customers, municipalities and businesses in the communities in which the Company operates as the country and world continue to work through the pandemic. Management believes it is still well positioned to withstand the continued financial impact from this health crisis as it stands by and works hand in hand with local businesses, individuals and households to be stronger than ever. Depending upon the duration of the COVID-19 pandemic and the adequacy of strategies put in place by local and federal governments, borrowers may not have the ability to repay their debts which may ultimately result in losses to the Company. The fiscal stimulus and relief programs appear to have delayed any materially adverse financial impact to the Company. Once these stimulus programs have been discontinued, the Company’s may experience deterioration in the credit portfolio and loan losses may materialize. The risk of credit losses will be contingent upon efficacy of vaccines including distribution and customers and businesses ability to return to pre-pandemic routines. Economic uncertainty remains high and volatility may continue. Management continues to closely monitor credit relationships, particularly those on payment deferral or adversely classified discussed in more detail below .

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.

At March 31, 2021, all mortgage-backed securities including collateralized mortgage obligations were securities of government sponsored enterprises, no private-label mortgage-backed securities or collateralized mortgage obligations were held in the securities portfolio. The Company’s investments in state and political subdivisions securities generally are municipal obligations that are general obligations supported by the general taxing authority of the issuer, and in some cases are insured. The obligations issued by school districts are supported by state aid. Primarily, these investments are issued by municipalities within New York State. The Company’s current securities investment strategy utilizes a risk management approach of diversified investing among three categories: short-, intermediate- and long-term. The emphasis of this approach is to increase overall investment securities yields while managing interest rate risk. The Company will only invest in high quality securities as determined by management’s analysis at the time of purchase. The Company generally does not engage in any derivative or hedging transactions, such as interest rate swaps or caps.

The Company considers numerous factors when determining whether a potential OTTI exists and the period over which the debt security is expected to recover. 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 March 31, 2021. Management believes that the reasons for the decline in fair value are due to lower interest rates and partially due to COVID-19 uncertainty at the reporting date. There were no transfers of securities available-for-sale to held-to-maturity during the three and nine months ended March 31, 2021 or 2020. During the three and nine months ended March 31, 2021 and 2020, 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 and nine months ended March 31, 2021 and 2020. The estimated fair values of debt securities at March 31, 2021, 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 and nine months ended March 31, 2021 or 2020.

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 March 31, 2021 and June 30, 2020 are summarized as follows: (In thousands) March 31, 2021 June 30, 2020 Residential real estate: Residential real estate $ 305,267 $ 279,332 Residential construction and land 8,467 11,847 Multi-family 37,470 25,104 Commercial real estate: Commercial real estate 454,792 381,415 Commercial construction 66,913 74,920 Consumer loan: Home equity 18,957 22,106 Consumer installment 4,499 4,817 Commercial loans 194,515 213,119 Total gross loans 1,090,880 1,012,660 Allowance for loan losses (19,668 ) (16,391 ) Unearned origination fees and costs, net (2,714 ) (2,747 ) Loans receivable, net $ 1,068,498 $ 993,522 The Bank of Greene County continues working with borrowers through the current pandemic. The Company instituted a loan deferment program in response to the COVID-19 pandemic whereby deferral of principal payments or principal and interest payments have been provided and correspond to the length of the National Emergency as defined under the CARES Act and extended under the Consolidated Appropriations Act which was signed into law on December 27, 2020. Under Section 4013 of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), loans less than 30 days past due as of March 31, 2020 will be considered current for COVID-19 modifications. Provisions under Section 4013 of the CARES Act were extended as part of the Consolidated Appropriations Act signed into law on December 27, 2020. A financial institution can suspend the requirements under GAAP for loan modifications related to COVID-19 that would otherwise be categorized as a troubled debt restructuring (“TDR”), and suspend any determination of a loan modified as a result of COVID-19 as being a TDR, including the requirement to determine impairment for accounting purposes . 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 85.0% of the appraised value of the property. 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 85.0% or less, 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. During the quarter ended March 31, 2021, the Company had on average outstanding $77.6 million in PPP loans which are unsecured commercial loans and are 100% guaranteed by the Small Business Administration. Loan balances by internal credit quality indicator at March 31, 2021 are shown below.

Loans classified as substandard or special mention totaled $43.0 million at March 31, 2021 and $32.8 million at June 30, 2020, an increase of $10.2 million. Loans classified as substandard or special mention increased due to insufficient cash flows and revenues for commercial real estate and commercial loans related to the COVID-19 pandemic. These newly classified loans were all performing as of March 31, 2021. 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 March 31, 2021 and June 30, 2020. Loans on nonaccrual status totaled $2.7 million at March 31, 2021 of which $752,000 were in the process of foreclosure. At March 31, 2021, there were six residential loans in the process of foreclosure totaling $450,000 with the remainder in commercial loans.

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. The table below details additional information related to nonaccrual loans for the three and nine months ended March 31: For the three months ended March 31, For the nine months ended March 31 (In thousands) 2021 2020 2021 2020 Interest income that would have been recorded if loans had been performing in accordance with original terms $ 43 $ 64 $ 174 $ 218 Interest income that was recorded on nonaccrual loans 36 51 116 143 In order to assist borrowers through the COVID-19 pandemic, the Company instituted a loan deferment program in response to the COVID-19 pandemic whereby deferral of principal and/or interest payments have been provided and correspond to the length of the National Emergency as defined under the CARES Act and extended under the Consolidated Appropriations Act which was signed into law on December 27, 2020. Payment deferrals consisted of either principal deferrals or full payment deferrals. Based on guidance provided by bank regulators on March 22, 2020 regarding deferrals granted due to COVID-19, these have not been reported as delinquent and we will continue to recognize interest income during the deferral period. At March 31, 2021, there were eight loans totaling $248,000 on nonaccrual that previously participated in this loan deferment program due to COVID-19. Impaired Loan Analysis The Company identifies impaired loans and measures the impairment in accordance with FASB ASC subtopic “ Receivables – Loan Impairment.” The tables below detail additional information on impaired loans at the date or periods indicated: At March 31, 2021 For the three months ended March 31, 2021 For the nine months ended March 31, 2021 (In thousands) Recorded Investment Unpaid Principal Related Allowance Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized With no related allowance recorded: Residential real estate $ 378 $ 378 $ - $ 381 $ 1 $ 392 $ 11 Multi-family - - - - - 40 - Commercial real estate 300 300 - 307 - 321 3 Home equity 229 229 - 230 - 173 - Commercial loans 103 103 - 105 - 164 8 Impaired loans with no allowance 1,010 1,010 - 1,023 1 1,090 22 With an allowance recorded: Residential real estate 730 730 113 710 2 1,053 27 Commercial construction 102 102 27 102 - 102 - Home equity 321 321 74 321 2 381 12 Commercial loans 1,756 1,756 73 1,235 85 417 110 Impaired loans with allowance 2,909 2,909 287 2,368 89 1,953 149 Total impaired: Residential real estate 1,108 1,108 113 1,091 3 1445 38 Multi-family - - - - - 40 - Commercial real estate 300 300 - 307 - 321 3 Commercial construction 102 102 27 102 - 102 - Home equity 550 550 74 551 2 554 12 Commercial loans 1,859 1,859 73 1,340 85 581 118 Total impaired loans $ 3,919 $ 3,919 $ 287 $ 3,391 $ 90 $ 3,043 $ 171 At June 30, 2020 For the three months ended March 31, 2020 For the nine months ended March 31, 2020 (In thousands) Recorded Investment Unpaid Principal Related Allowance Average Recorded Investment Interest Income Average Investment Interest Income Recognized With no related allowance recorded: Residential real estate $ 868 $ 868 $ - $ 702 11 645 52 Multi-family 123 123 - 42 - 14 - Commercial real estate 344 344 - 362 1 549 13 Home equity 128 128 - 136 - 177 - Commercial loans 145 145 - 163 - 134 1 Impaired loans with no allowance 1,608 1,608 - 1,405 12 1,519 66 With an allowance recorded: Residential real estate 995 995 127 1,176 7 1,227 39 Multi-family - - - 85 - 72 1 Commercial real estate - - - - - 35 3 Commercial construction 102 102 15 102 - 102 - Home equity 431 431 73 449 7 414 21 Commercial loans 134 134 13 165 5 151 9 Impaired loans with allowance 1,662 1,662 228 1,977 19 2,001 73 Total impaired: Residential real estate 1,863 1,863 127 1,878 18 1,872 91 Multi-family 123 123 - 127 - 86 1 Commercial real estate 344 344 - 362 1 584 16 Commercial construction 102 102 15 102 - 102 - Home equity 559 559 73 585 7 591 21 Commercial loans 279 279 13 328 5 285 10 Total impaired loans $ 3,270 $ 3,270 $ 228 $ 3,382 31 3,520 139 The table below details loans that have been modified as a troubled debt restructuring.

There were no loans that were modified as a trouble debt restructuring during the three and nine months ended March 31, 2020. There were no loans that had been modified as a troubled debt restructuring during the twelve months prior to June 30, 2020 or 2019 which have subsequently defaulted during the three and nine months ended March 31, 2021 or 2020, respectively. The Bank of Greene County continues working with borrowers through the current pandemic. During fiscal 2020, the Company instituted a loan deferment program in response to the COVID-19 pandemic whereby deferral of principal and/or interest payments have been provided and correspond to the length of the National Emergency as defined under the CARES Act and extended under the Consolidated Appropriations Act which was signed into law on December 27, 2020. At March 31, 2021, the Company still had $18.8 million consisting of 30 loans on payment deferral as a result of the pandemic, which is down from $193.5 million consisting of 706 loans at June 30, 2020. Based on guidance provided by bank regulators on March 22, 2020 regarding deferrals granted due to COVID-19, we have not reported these loans as delinquent and will continue to recognize interest income during the deferral period. These loans will be closely monitored to determine collectability and accrual and delinquency status will be updated as deemed appropriate. The banking regulatory agencies provided guidance as to how certain short-term modifications would not be considered TDRs, and have subsequently confirmed that such guidance could be applicable for loans that do not qualify for favorable accounting treatment under Section 4013 of the CARES Act. Based on this guidance, the Company does not believe that TDRs will significantly change as a result of the modifications granted. 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 commercial 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. Included within consumer installment loan charge-offs and recoveries are deposit accounts that have been overdrawn in excess of 60 days. With continued growth in the number of deposit accounts, charge-off activity within this category has also grown, as can be seen from the tables below. 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. The allowance for loan losses is increased by a provision for loan losses (which results in a charge to expense) and recoveries of loans previously charged off and is reduced by charge-offs. The Bank of Greene County recognizes that strategies put in place to assist borrowers through the COVID-19 pandemic may not be sufficient to fully mitigate the impact to borrowers and that it is likely that a portion of the loan portfolio will default and result in losses to The Bank of Greene County. As a result, The Bank of Greene County has increased its provision for loan losses for the three and nine months ended March 31, 2021 to $1.4 million and $3.9 million, respectively, from $1.4 million and $2.7 million for the three and nine months ended March 31, 2020, respectively. The adequacy of containment strategies introduced to mitigate the impact of COVID-19 to both the economy and local businesses remains uncertain. The increase in provision for loan losses for the nine months ended March 31, 2021 was due to the impact of the COVID-19 pandemic as well as growth in gross loans and an increase in loans adversely classified. Management continues to monitor changes within its economic environment and loan portfolio adjusting the allowance for loan loss as necessary to remain adequately reserved. The following tables set forth the activity and allocation of the allowance for loan losses by loan category during and at the periods indicated. The allowance is allocated to each loan category based on historical loss experience and economic conditions.

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 March 31, 2021 and June 30, 2020 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 for similar assets or liabilities in active markets, 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 For Identical Assets Significant Other Observable Significant Unobservable Inputs (In thousands) March 31, 2021 (Level 1) (Level 2) (Level 3) Assets: U.S. Government sponsored enterprises $ 12,633 $ - $ 12,633 $ - U.S. Treasury securities 19,620 - 19,620 - State and political subdivisions 210,014 - 210,014 - Mortgage-backed securities-residential 39,416 - 39,416 - Mortgage-backed securities-multi-family 119,363 - 119,363 - Corporate debt securities 3,140 3,140 - - Securities available-for-sale $ 404,186 $ 3,140 $ 401,046 $ - Equity securities 286 286 - - Total securities measured at fair value $ 404,472 $ 3,426 $ 401,046 $ - Fair Value Measurements Using Quoted Prices In Active Markets For Significant Other Observable Inputs Significant Unobservable Inputs (In thousands) June 30, 2020 (Level 1) (Level 2) (Level 3) Assets: U.S. Government sponsored enterprises $ 504 $ - $ 504 $ - State and political subdivisions 177,107 - 177,107 - Mortgage-backed securities-residential 15,528 - 15,528 - Mortgage-backed securities-multi-family 28,910 - 28,910 - Corporate debt securities 4,660 4,660 - - Securities available-for-sale $ 226,709 $ 4,660 $ 222,049 $ - Equity securities 267 267 - - Total securities measured at fair value $ 226,976 $ 4,927 $ 222,049 $ - 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. The fair values for loans are measured 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 and borrowings from other banks are estimated using discounted cash flows and interest rates currently being offered on similar borrowings. Fair value for subordinated notes payable is estimated based upon quotes from its pricing service based on a discounted cash flow methodology or utilizes observations of recent highly-similar transactions. 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 March 31, 2021 and June 30, 2020, the estimated fair values of these off-balance sheet financial instruments were immaterial, and are therefore excluded from the table below.

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 dilutive or anti-dilutive securities or contracts outstanding during the three and nine months ended March 31, 2021 and 2020.

Impact of Recent Accounting Pronouncements	(9) Impact of Recent Accounting Pronouncements The following accounting standards were adopted in the first quarter ended September 30, 2020: 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 non-public 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 did not have a material impact on our consolidated results of operations or financial position. In April 2019, the FASB issued an Update (ASU 2019-04), Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments to Topic 326 and other topics in this Update include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses TRG meetings. The amendments related to Update 2016-13 have the same effective dates as Update 2016-13 and are described in the next paragraph below. The ASU also covered a number of issues that related to hedge accounting including: Partial-Term Fair Value Hedges of Interest Rate Risk, Amortization of Fair Value Hedge Basis Adjustments, Disclosure of Fair Value Hedge Basis Adjustments, Consideration of the Hedged Contractually Specified Interest Rate under the Hypothetical Derivative Method, Scoping for Not-for-Profit Entities, Hedge Accounting Provisions Applicable to Certain Private Companies and Not-for-Profit Entities, and Application of a First-Payments-Received Cash Flow Hedging Technique to Overall Cash Flows on a Group of Variable Interest Payments. The amendments related to Topic 815 are effective with the adoption of the amendments in Update 2017-12. The Company does not have any transactions that are applicable to Update 2017-12, and therefore the adoption of Update 2017-12 and related provisions of Update 2019-04, did not have any impact on our consolidated results of operations or financial position. The ASU also covers Transition Guidance For Codification Improvements specific to ASU 2016-01. The following topics were covered within ASU 2019-04: Scope Clarifications, Held-to-Maturity Debt Securities Fair Value Disclosures, Applicability of Topic 820 to the Measurement Alternative, and Remeasurement of Equity Securities at Historical Exchange Rates. The amendments related to ASU 2016-01 are effective for fiscal years beginning after December 15, 2019. The adoption of this guidance did not have a material impact on our consolidated results of operations or financial position. Accounting Pronouncements to be adopted in future periods 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. 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). In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which aligns the implementation date for nonpublic entities’ annual financial statements with the implementation date for their interim financial statements and clarifies the scope of the guidance in the amendments in ASU 2016-13. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments to Topic 326 and other topics in ASU 2019-04 include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses TRG meetings. The amendments clarify or address stakeholders’ specific issues about certain aspects of the amendments in Update 2016-13 on a number of different topics, including the following: Accrued Interest, Transfers between Classifications or Categories for Loans and Debt Securities, Recoveries, Consideration of Prepayments in Determining the Effective Interest Rate, Consideration of Estimated Costs to Sell When Foreclosure Is Probable, Vintage Disclosures— Line-of-Credit Arrangements Converted to Term Loans, and Contractual Extensions and Renewals. The effective dates and transition requirements for the amendments related to this Update are the same as the effective dates and transition requirements in Update 2016-13. In November 2019, the FASB issued ASU 2019-11 Codification Improvements to Topic 326 Financial Instruments Credit Losses provides additional clarification to specific issues about certain aspects of the amendments in Update 2016-13 related to measuring the allowance for loan losses under the new guidance. 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. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, excluding small reporting companies such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In November 2019, FASB issued ASU 2019-10, Financial Instruments – Credit Losses which amends the implementation effective date for small reporting companies, such as the Company, and non-public business entities, for fiscal years beginning after December 15, 2022. 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. 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. In March 2020, the FASB issued an Update (ASU 2020-04), Reference Rate Reform (Topic 848). On January 7, 2021, the FASB issued (ASU 2021-01), which refines the scope of ASC 848 and clarifies some of its guidance. The ASU and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permits relief solely for reference rate reform actions and permits different elections over the effective date for legacy and new activity. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The Company’s initial evaluation of LIBOR exposure appears to be minimal and limited to a couple of participation loans or risk participation agreements. The Company is working with the other lead lenders to determine if any potential contract modifications are needed. In October 2020, the FASB issued an Update (ASU 2020-08), Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs. The amendments affect the guidance in ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in that Update shortened the amortization period for certain purchased callable debt securities held at a premium by requiring that entities amortize the premium associated with those callable debt securities within the scope of paragraph 310-20-25-33 to the earliest call date. The Board noted in paragraph BC21 of Update 2017-08 that if the security contained additional future call dates, an entity should consider whether the amortized cost basis exceeded the amount repayable by the issuer at the next call date. If so, the excess should be amortized to the next call date. The amendments in ASU 2020-08 clarify the Board’s intent that an entity should reevaluate whether a callable debt security that has multiple call dates is within the scope of paragraph 310-20-35-33 for each reporting period. 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, 2020. Early application is not permitted. All entities should apply the amendments in this Update on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company is in the early stages of evaluation of the guidance.

All of the Company's revenue from contracts with customers in the scope of ASC 606 is recognized within non-interest income, with the exception of net gains and losses from sales of foreclosed real estate, which is recognized within non-interest expense. The following table presents revenues subject to ASC 606 for the three and nine months ended March 31, 2021 and 2020, respectively. For the three months ended For the nine months ended March 31, March 31, (In thousands) 2021 2020 2021 2020 Service charges on deposit accounts Insufficient funds fees $ 704 $ 928 $ 2,230 $ 2,950 Deposit related fees 38 40 112 120 ATM/point of sale fees 73 66 213 200 Total service charges 815 1,034 2,555 3,270 Interchange fee and incentive income Debit card interchange and incentive fees 951 698 2,761 2,196 E-commerce fee income E-commerce fees 25 24 82 90 Investment services income Investment services 174 120 551 433 Sales of assets Net gain (loss) on foreclosed real estate 7 (57 ) 92 19 Service Charges on Deposit Accounts : The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which included services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are recognized at the time the maintenance occurs. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance. Debit Card Interchange and Incentive Fee Income : The Company earns interchange fees from debit cardholder transactions conducted through the Visa DPS payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to cardholder. The Company also earns contract incentives to participate in the Visa network. E-commerce income : The Company earns fees for merchant transaction processing services provided to its business customers by a third party service provider. The fees represent a percentage of the monthly transaction activity net of related costs, and are received from the service provider on a monthly basis. Investment Services Income : The Company earns fees from investment brokerage services provided to its customers by a third-party service provider. The Company receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The Company (i) acts as an agent in arranging the relationship between the customer and the third-party service provider and (ii) does not control the services rendered to the customers. Investment brokerage fees are presented net of related costs. Net Gains/Losses on Sales of Foreclosed Real Estate : The Company records a gain or loss from the sale of foreclosed real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of foreclosed real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed real estate asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.

Basis of Presentation (Policies

Basis of Presentation (Policies)	9 Months Ended
	Mar. 31, 2021
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, 2020 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 and nine months ended March 31, 2021 and 2020 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, 2020, 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. The Company had no reclassifications from amounts in the prior year’s consolidated financial statements to conform to the current year’s presentation. All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three and nine months ended March 31, 2021 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2021. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued and should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K. 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 and nine months ended March 31, 2021, other than those implemented to respond to the coronavirus pandemic (“COVID-19”) as developed and initiated by governmental laws and programs as discussed throughout this document such as the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) including the Paycheck Protection Program (“PPP”) developed under this law. 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	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 [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 and nine months ended March 31, 2021 or 2020.

Impact of Recent Accounting Pronouncements [Abstract]
Impact of Recent Accounting Pronouncements	The following accounting standards were adopted in the first quarter ended September 30, 2020: 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 non-public 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 did not have a material impact on our consolidated results of operations or financial position. In April 2019, the FASB issued an Update (ASU 2019-04), Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments to Topic 326 and other topics in this Update include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses TRG meetings. The amendments related to Update 2016-13 have the same effective dates as Update 2016-13 and are described in the next paragraph below. The ASU also covered a number of issues that related to hedge accounting including: Partial-Term Fair Value Hedges of Interest Rate Risk, Amortization of Fair Value Hedge Basis Adjustments, Disclosure of Fair Value Hedge Basis Adjustments, Consideration of the Hedged Contractually Specified Interest Rate under the Hypothetical Derivative Method, Scoping for Not-for-Profit Entities, Hedge Accounting Provisions Applicable to Certain Private Companies and Not-for-Profit Entities, and Application of a First-Payments-Received Cash Flow Hedging Technique to Overall Cash Flows on a Group of Variable Interest Payments. The amendments related to Topic 815 are effective with the adoption of the amendments in Update 2017-12. The Company does not have any transactions that are applicable to Update 2017-12, and therefore the adoption of Update 2017-12 and related provisions of Update 2019-04, did not have any impact on our consolidated results of operations or financial position. The ASU also covers Transition Guidance For Codification Improvements specific to ASU 2016-01. The following topics were covered within ASU 2019-04: Scope Clarifications, Held-to-Maturity Debt Securities Fair Value Disclosures, Applicability of Topic 820 to the Measurement Alternative, and Remeasurement of Equity Securities at Historical Exchange Rates. The amendments related to ASU 2016-01 are effective for fiscal years beginning after December 15, 2019. The adoption of this guidance did not have a material impact on our consolidated results of operations or financial position. Accounting Pronouncements to be adopted in future periods 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. 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). In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which aligns the implementation date for nonpublic entities’ annual financial statements with the implementation date for their interim financial statements and clarifies the scope of the guidance in the amendments in ASU 2016-13. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments to Topic 326 and other topics in ASU 2019-04 include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses TRG meetings. The amendments clarify or address stakeholders’ specific issues about certain aspects of the amendments in Update 2016-13 on a number of different topics, including the following: Accrued Interest, Transfers between Classifications or Categories for Loans and Debt Securities, Recoveries, Consideration of Prepayments in Determining the Effective Interest Rate, Consideration of Estimated Costs to Sell When Foreclosure Is Probable, Vintage Disclosures— Line-of-Credit Arrangements Converted to Term Loans, and Contractual Extensions and Renewals. The effective dates and transition requirements for the amendments related to this Update are the same as the effective dates and transition requirements in Update 2016-13. In November 2019, the FASB issued ASU 2019-11 Codification Improvements to Topic 326 Financial Instruments Credit Losses provides additional clarification to specific issues about certain aspects of the amendments in Update 2016-13 related to measuring the allowance for loan losses under the new guidance. 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. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, excluding small reporting companies such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In November 2019, FASB issued ASU 2019-10, Financial Instruments – Credit Losses which amends the implementation effective date for small reporting companies, such as the Company, and non-public business entities, for fiscal years beginning after December 15, 2022. 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. 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. In March 2020, the FASB issued an Update (ASU 2020-04), Reference Rate Reform (Topic 848). On January 7, 2021, the FASB issued (ASU 2021-01), which refines the scope of ASC 848 and clarifies some of its guidance. The ASU and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permits relief solely for reference rate reform actions and permits different elections over the effective date for legacy and new activity. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The Company’s initial evaluation of LIBOR exposure appears to be minimal and limited to a couple of participation loans or risk participation agreements. The Company is working with the other lead lenders to determine if any potential contract modifications are needed. In October 2020, the FASB issued an Update (ASU 2020-08), Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs. The amendments affect the guidance in ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in that Update shortened the amortization period for certain purchased callable debt securities held at a premium by requiring that entities amortize the premium associated with those callable debt securities within the scope of paragraph 310-20-25-33 to the earliest call date. The Board noted in paragraph BC21 of Update 2017-08 that if the security contained additional future call dates, an entity should consider whether the amortized cost basis exceeded the amount repayable by the issuer at the next call date. If so, the excess should be amortized to the next call date. The amendments in ASU 2020-08 clarify the Board’s intent that an entity should reevaluate whether a callable debt security that has multiple call dates is within the scope of paragraph 310-20-35-33 for each reporting period. 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, 2020. Early application is not permitted. All entities should apply the amendments in this Update on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company is in the early stages of evaluation of the guidance.

[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.
