Accounting Policies [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Nature of Operations PCSB Bank is a community-oriented financial institution that provides financial services to individuals and businesses within its market area of Putnam, Southern Dutchess, Rockland and Westchester Counties in New York. The Bank is a state-chartered commercial bank, and its deposits are insured up to applicable limits by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”). The Bank’s primary regulators are the FDIC and the NYSDFS. Basis of Presentation The unaudited consolidated financial statements contained herein reflect all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Such adjustments are the only adjustments reflected in the consolidated financial statements contained herein. The results of operations for the current period presented are not necessarily indicative of the results of operations that may be expected for the entire current fiscal year. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended June 30, 2021, included in the Company's Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or equity. Loans Held For Sale Loans held for sale are those loans which management has the intent to sell in the foreseeable future, and are carried at the lower of aggregate cost or market value. Net unrealized losses, if any, are recognized by a valuation allowance through a charge to noninterest income. Realized gains and losses on the sale of loans are recognized on the trade date and are determined by the difference between the sale proceeds and the carrying value of the loans. Loans may be sold with servicing rights released or retained. At the time of the sale, management records a servicing asset for the value of any retained servicing rights, which represents the present value of the differential between the contractual servicing fee and adequate compensation, defined as the fee a sub-servicer would require to assume the role of servicer, after considering the estimated effects of prepayments. Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the transferor does not maintain effective control over the transferred assets through either (a) an agreement that both entitles and obligates the transferor to repurchase or redeem the assets before maturity or (b) the ability to unilaterally cause the holder to return specific assets, other than through a cleanup call. Assets Held For Sale ssets held for sale are those assets which management has the intent to sell in the foreseeable future, and are carried at the lower of aggregate cost or fair value, less estimated costs to sell, in the period in which the held for sale criteria are met and every subsequent period until the asset is sold. The carrying amount of the asset is adjusted for subsequent increases or decreases in its fair value, less estimated cost to sell, except that any subsequent increase cannot exceed the cumulative loss previously recognized. Such assets are not depreciated or amortized while they are classified as held for sale. Realized gains and losses on the sale of the asset is recognized when the asset is sold and is determined by the difference between the sale proceeds and the carrying value of the asset. Assets classified as held for sale totaled $1.5 million as of both September 30, 2021 and June 30, 2021 and are included in other assets on the consolidated balance sheet Risks and Uncertainties: The COVID-19 pandemic has created extensive disruptions to the global and U.S. economies and to the lives of individuals throughout the world. Governments, businesses, and the public have taken unprecedented actions to contain the spread of COVID-19 and to mitigate its effects, including vaccination mandates, quarantines, travel bans, shelter-in-place orders, closures of businesses and schools, fiscal and monetary stimulus, and legislation designed to deliver financial aid and other relief. While the scope, duration, and full effects of COVID-19 continue to evolve and are not fully known, the pandemic and the efforts to contain it have disrupted global economic activity, adversely affected the functioning of financial markets, impacted market interest rates, increased economic and market uncertainty, and disrupted trade and supply chains. Many of the emergency actions taken to mitigate the effects of the pandemic have since been reduced or eliminated, resulting in an improved local and national economic environment, however t he ultimate financial impact of the pandemic on our business is still unknown at this time. The pandemic may continue to adversely impact consumers and several industries within our geographic footprint and impair the ability of the Company’s customers to fulfill their contractual obligations to the Company. This could cause the Company to experience a material adverse effect on our business operations, asset valuations, financial condition, and results of operations. Material adverse impacts may include, but are not limited to, the valuation impairments of the Company’s intangible assets, investments, loans, or deferred tax assets. Additionally, i t is reasonably possible that the Company’s allowance for loan loss estimate as of September 30, 2021 could change in the near term and could result in a material change to the Company’s provision for loan losses, earnings and capital.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 2 . Recent Accounting Pronouncements The pronouncements discussed below are not intended to be an all-inclusive list, but rather only those pronouncements that the Company has determined could potentially have a material impact on our financial position, results of operations or disclosures. There were no accounting standards adopted in the current period. Future Application of Accounting Pronouncements Previously Issued In June 2016, the FASB issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 affects entities holding financial assets that are not accounted for at fair value through net income, including loans, debt securities, and other financial assets. The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by recording an allowance for current expected credit losses. In October 2019, the FASB unanimously voted to delay the implementation of the standard for three years for certain companies, including small reporting companies (as defined by the SEC), non-SEC public companies and private companies. The Company currently qualifies as a small reporting company and is subject to the delayed implementation. Therefore, t he amendments in this update will be effective for the Company for the fiscal year beginning on July 1, 2023, including interim periods within that fiscal year. The Company is actively working through the provisions of the Update. Management has established a steering committee which is identifying the methodologies and the additional data requirements necessary to implement the Update and has engaged a third-party software service provider to assist in the Company's implementation. Management is currently evaluating the impact that ASU 2016-13 will have on the Company’s consolidated financial position, results of operations and disclosures.

Non-U.S. government and agency obligations are internally pass rated and are subject to quarterly credit monitoring. There were no securities for which the Company believes it is not probable that it will collect all amounts due according to the contractual terms of the security as of September 30, 2021 or June 30, 2021. Management believes the unrealized losses are primarily a result of changes in interest rates. The Company has determined that it does not intend to sell, or it is not more likely than not that it will be required to sell, its securities that are in an unrealized loss position prior to the recovery of its amortized cost basis. Therefore, the Company did not consider any securities to be other-than-temporarily impaired as of September 30, 2021 or June 30, 2021.

Such loans are excluded because the loans are in pools that are considered performing. The discounts arising from recording these loans at fair value upon acquisition were due in part to credit quality and the accretable yield is being recognized as interest income over the life of the loans based on expected cash flows.

Troubled Debt Restructurings The terms of certain loans have been modified as troubled debt restructurings (“TDR”). The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. All TDRs are considered impaired loans. As of September 30, 202 1 and June 30, 2021, the Company had 8 and 12 loans, classified as TDRs totaling $1.6 million and $3.1 million, including $1.2 million and $2.7 million, respectively, of loans still accruing interest. The Company has allocated $119,000 and $121,000, respectively, of specific reserves to customers whose loan terms have been modified in TDRs as of both September 30, 2021 and June 30, 2021 As of September 30, 2021, the Company has committed to lend an additional $3,000 to customers with outstanding loans that are classified as TDRs The Company did not modify any loans during the three months ended September 30, 2021 or 2020 that were classified as TDRs. There were no defaults of troubled debt restructurings occurring in the three months ended September 30, 2021 or September 30, 2020 that were modified in the twelve months prior to default. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law. Section 4013 of the CARES Act, “Temporary Relief From Troubled Debt Restructurings,” provides banks the option to temporarily suspend certain requirements under U.S. GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. On December 27, 2020, the Consolidated Appropriations Act 2021 was signed into law. Section 541 of this legislation, “Extension of Temporary Relief From Troubled Debt Restructurings and Insurer Clarification,” extends Section 4013 of the CARES Act to the earlier of January 1, 2022 or 60 days after the termination of the national emergency declared relating to COVID-19. Additionally, on April 7, 2020, the banking agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, issued a statement, “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working With Customers Affected by the Coronavirus (Revised)” (“Interagency Statement”), to encourage banks to work prudently with borrowers and to describe the agencies’ interpretation of how accounting rules under ASC 310-40, “Troubled Debt Restructurings by Creditors,” apply to certain COVID-19-related modifications. During the three months ended September 30, 2021, the Company granted or extended loan payment deferrals for 5 commercial mortgage, construction and commercial loans totaling $3.7 million. In accordance with either the CARES Act (as amended) or Interagency Statement, these modifications are not considered troubled debt restructurings. The Company had 11 and 19 loans totaling $18.5 million and $27.3 million on loan payment deferral as of September 30, 2021 and June 30, 2021, respectively. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company utilizes the same grading process for acquired loans as it does for originated loans. The Company uses the following definitions for risk ratings: Special Mention – Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above-described process and loans in groups of homogenous loans are considered to be pass rated loans. These loans are monitored based on delinquency and performance. Based on the most recent analysis performed, the risk category of loans by portfolio segment is as follows (in thousands): September 30, 2021 Pass Special Mention Substandard Total Residential mortgages $ 217,832 $ 1,986 $ 1,917 $ 221,735 Commercial mortgages 821,074 1,605 15,342 838,021 Construction 10,526 1,113 - 11,639 Commercial loans 117,677 485 3,869 122,031 Home equity lines of credit 23,947 556 433 24,936 Consumer and overdrafts 394 - - 394 Total $ 1,191,450 $ 5,745 $ 21,561 $ 1,218,756 June 30, 2021 Pass Special Mention Substandard Total Residential mortgages $ 219,901 $ 2,480 $ 1,924 $ 224,305 Commercial mortgages 809,660 1,615 15,349 826,624 Construction 9,038 1,113 - 10,151 Commercial loans 146,275 491 3,892 150,658 Home equity lines of credit 24,400 602 437 25,439 Consumer and overdrafts 345 - - 345 Total $ 1,209,619 $ 6,301 $ 21,602 $ 1,237,522 As of September 30, 2021, of the $18.5 million in loans in a COVID-19 related payment deferral, $8.2 million were pass-rated, with $1.7 million and $8.6 million rated special mention and substandard, respectively. As of June 30, 2021, of the $27.3 million in loans on deferral, $9.9 million were pass-rated, with $3.2 million and $14.2 million rated special mention and substandard, respectively. Purchased Credit Impaired Loans The Company has acquired loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans as of September 30, 2021 and June 30, 2021 is as follows (in thousands): September 30, June 30, 2021 2021 Residential mortgages $ 719 $ 720 Commercial mortgages 883 888 Home equity lines of credit 119 123 Carrying amount, net of allowance of $0 $ 1,721 $ 1,731 There was no provision for loan losses on purchased credit impaired loans during the three months ended September 30, 2021 or 2020.

Post-Retirement Benefits	Note 6 . Post-Retirement Benefits Employee Pension Plan The Company maintains a non-contributory defined benefit pension plan that covers employees meeting specific requirements as to age and length of service. The Company’s contributions to this qualified plan are determined on the basis of (i) the maximum amount that can be deducted for federal income tax purposes, and (ii) the amount determined by a consulting actuary as necessary to avoid an accumulated funding deficiency as defined by the Employee Retirement Income Security Act of 1974 (“ERISA”). Contributions are intended to provide for benefits attributed to service to date but also those expected to be earned in the future. Supplemental Executive Retirement Plans The Company also maintains unfunded and non-qualified supplemental executive retirement plans ("SERP") to provide pension benefits in addition to those provided under the qualified pension plan.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 7. Fair Value of Financial Instruments Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as general classification of such instruments pursuant to the valuation hierarchy, is set forth below. While management believes the Company’s valuation methodologies are appropriate and consistent with other financial institutions, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Investment Securities Impaired Loans Foreclosed Real Estate Foreclosed properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Credit Department, as well as a third-party specialist, where deemed appropriate, reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Once appraisals are considered appropriate, management discounts the appraised value for estimated selling costs, such as legal, broker, and property maintenance and insurance costs. The most recent analysis performed indicated discount rates ranging between 10% and 20% should be applied to properties with appraisals performed.

Management believes that as of September 30, 2021 and June 30, 2021, the Bank met all capital adequacy requirements to which it was subject, including the capital conservation buffer of 2.5%. Further, the most recent FDIC notification categorized the Bank as a well-capitalized institution under the prompt corrective action regulations. There have been no conditions or events since that notification that management believes have changed the Bank’s capital classification.

Earnings Per Share [Abstract]
Earnings Per Share ("EPS")	Note 9. Earnings Per Share (“EPS”) Basic EPS is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated in a similar matter, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method. Dilutive financial instruments include stock options and unvested restricted stock. The following table provides factors used in the earnings per share computation.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Note 10. Derivatives and Hedging Derivatives not designated as hedges may be used to manage the Company’s exposure to interest rate movements or to provide service to customers. The Company executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that the Company executes with a third party in order to minimize the net risk exposure resulting from such transactions. The Company presents interest rate swap assets and liabilities in other assets and other liabilities, respectively, in the Consolidated Balance Sheets. These interest rate swap agreements do not qualify for hedge accounting treatment, and therefore changes in fair value are reported in current period earnings. The following table presents summary information about the interest rate swaps as of September 30, 2021 and June 30, 2021 (dollars in thousands).

Revenue From Contract With Customer [Abstract]
Revenue From Contracts With Customers	Note 11. Revenue From Contracts With Customers In accordance with ASC 606, revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these services. The Company applies the following five steps to properly recognize revenue: 1. 2. Identify the performance obligations in the contract. 3. Determine the transaction price. 4. Allocate the transaction price to performance obligations in the contract. 5. Recognize revenue when (or as) the Company satisfies a performance obligation. The following table presents summary information about sources of revenue from contracts with customers for the periods indicated (in thousands). Three Months Ended September 30, 2021 2020 Noninterest income: Service charges on deposits $ 183 $ 162 Interchange fees 156 131 Other fees and service charges (1) 62 29 Fees and service charges 401 322 Bank-owned life insurance (1) 192 132 Swap income (1) - 129 Other noninterest income (1) 20 11 Total noninterest income $ 613 $ 594 (1) Fees and 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 include services such as ATM use fees, stop payments, 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 earned over the course of the month, representing the period over which the Company satisfied the performance obligation. 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. Interchange Income . The Company earns interchange fees from debit cardholder transactions conducted through various payment networks. 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 the cardholder. Gain 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.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	Note 12. Stock-Based Compensation On October 24, 2018, the Company’s shareholders approved the PCSB Financial Corporation 2018 Equity Incentive Plan (the “Plan”), which permits the grant of stock options and restricted stock and/or restricted stock units. The total number of shares that may be granted under the Plan is 2,543,115, of which 1,816,511 shares may be granted as stock options and 726,604 shares may be granted as restricted stock and restricted stock units. Total compensation cost that has been charged against income for the Plan was $810,000 and $829,000 for the three months ended September 30, 2021 and September 30, 2020, respectively. Restricted Stock Awards (“RSAs”) RSAs awarded under the Plan provide for the issuance of shares to both employees and non-employee directors. These awards generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award. All awards were made at the fair value of common stock on the grant date. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at grant date. The fair value of the stock was determined to be the closing price of the stock on the NASDAQ exchange. Total shares available for grant under the Plan are 726,604, of which 549,467 shares were granted as of September 30, 2021. The following table presents a summary of RSA activity during the period ended September 30, 2021. Number of Shares Weighted-Average Grant Date Fair Value Unvested granted shares outstanding at July 1, 2021 322,580 $ 18.95 Shares granted 8,000 17.66 Shares vested (600 ) 12.34 Shares forfeited - - Unvested granted shares at September 30, 2021 329,980 $ 18.93 As of September 30, 2021, there was $4.5 million of total unrecognized compensation cost related to non-vested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 2.4 years. Stock Option Awards Stock options awarded to employees under the Plan are considered incentive stock options (ISOs), up to applicable limits. Option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. Those issued to non-employee directors, as well as those exceeding ISO limitations, are considered non-qualified stock options (NQSOs). Options generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award, however, may not vest more rapidly than over a three-year The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatilities of a peer group of publicly traded financial institutions. The expected term of options granted is based on the simplified “mid-point” approach which utilizes the weighted average vesting period and contractual term. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The fair value of options granted during the three months ended September 30, 2021, was determined using the following weighted-average assumptions as of grant date. Risk-free interest rate 1.00 % Expected term (in years) 6.25 Expected stock price volatility 35.91 % Dividend yield 1.36 % Weighted average fair value of options granted $ 5.50 Total options available for grant under the Plan are 1,816,511, of which 1,320,963 options were granted as of September 30, 2021 .

Leases [Abstract]
Leases	Note 13. Leases As of September 30, 2021, the Company leases real estate for eleven branch offices and one administrative office, including its corporate headquarters, under various operating lease agreements. The Company’s leases have maturities which range from 2022 to 2041, some of which include lessee options to extend the lease term. The weighted average remaining life of the lease terms for these leases was 9.58 years as of September 30, 2021. The operating lease asset and lease liability are determined at the commencement date of the lease based on the present value of the lease payments. As most of our leases do not provide an implicit rate, the Company used its incremental borrowing rate, the rate of interest to borrow on a collateralized basis for a similar term, at the lease commencement date. The Company utilized a weighted average discount rate of 2.39% in determining the lease liability as of September 30, 2021. The Company made a policy election to exclude the recognition requirements of ASC 842 to short-term leases, those leases with original terms of 12 months or less. Short-term lease payments are recognized in the income statement on a straight-line basis over the lease term. The Company had no short-term lease cost for the three months ended September 30, 2021 or 2020. Certain leases may include one or more options to renew. The exercise of lease renewal options is typically at the Company’s discretion and are included in the operating lease liability if it is reasonably certain that the renewal option will be exercised. Certain real estate leases may contain lease and non-lease components, such as common area maintenance charges, real estate taxes, and insurance, which are generally accounted for separately and are not included in the measurement of the lease liability since they are generally able to be segregated. The Company does not sublease any of its leased properties. There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the three months ended September 30, 2021 or 2020. Total operating lease cost was $504,000 for both, the three months ended September 30, 2021 and 2020. The right-of-use asset, included in premises and equipment, net, was $9.2 million and the corresponding lease liability, included in other liabilities was $9.5 million as of September 30, 2021. Future minimum lease payments for the fiscal years ending June 30 and a reconciliation of undiscounted lease cash flows and the lease liability recognized in the consolidated balance sheet as of September 30, 2021 is shown below: (dollars in thousands) 2022 $ 1,523 2023 1,940 2024 1,569 2025 1,276 2026 748 Thereafter 3,802 Total future minimum lease payments (undiscounted) 10,858 Discounting effect on cash flows (1,384 ) Lease liability (discounted) $ 9,474

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations PCSB Bank is a community-oriented financial institution that provides financial services to individuals and businesses within its market area of Putnam, Southern Dutchess, Rockland and Westchester Counties in New York. The Bank is a state-chartered commercial bank, and its deposits are insured up to applicable limits by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”). The Bank’s primary regulators are the FDIC and the NYSDFS.
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements contained herein reflect all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Such adjustments are the only adjustments reflected in the consolidated financial statements contained herein. The results of operations for the current period presented are not necessarily indicative of the results of operations that may be expected for the entire current fiscal year. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended June 30, 2021, included in the Company's Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or equity.
Loans Held For Sale	Loans Held For Sale Loans held for sale are those loans which management has the intent to sell in the foreseeable future, and are carried at the lower of aggregate cost or market value. Net unrealized losses, if any, are recognized by a valuation allowance through a charge to noninterest income. Realized gains and losses on the sale of loans are recognized on the trade date and are determined by the difference between the sale proceeds and the carrying value of the loans. Loans may be sold with servicing rights released or retained. At the time of the sale, management records a servicing asset for the value of any retained servicing rights, which represents the present value of the differential between the contractual servicing fee and adequate compensation, defined as the fee a sub-servicer would require to assume the role of servicer, after considering the estimated effects of prepayments. Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the transferor does not maintain effective control over the transferred assets through either (a) an agreement that both entitles and obligates the transferor to repurchase or redeem the assets before maturity or (b) the ability to unilaterally cause the holder to return specific assets, other than through a cleanup call.
Assets Held For Sale	Assets Held For Sale ssets held for sale are those assets which management has the intent to sell in the foreseeable future, and are carried at the lower of aggregate cost or fair value, less estimated costs to sell, in the period in which the held for sale criteria are met and every subsequent period until the asset is sold. The carrying amount of the asset is adjusted for subsequent increases or decreases in its fair value, less estimated cost to sell, except that any subsequent increase cannot exceed the cumulative loss previously recognized. Such assets are not depreciated or amortized while they are classified as held for sale. Realized gains and losses on the sale of the asset is recognized when the asset is sold and is determined by the difference between the sale proceeds and the carrying value of the asset. Assets classified as held for sale totaled $1.5 million as of both September 30, 2021 and June 30, 2021 and are included in other assets on the consolidated balance sheet
Risks and Uncertainties	Risks and Uncertainties: The COVID-19 pandemic has created extensive disruptions to the global and U.S. economies and to the lives of individuals throughout the world. Governments, businesses, and the public have taken unprecedented actions to contain the spread of COVID-19 and to mitigate its effects, including vaccination mandates, quarantines, travel bans, shelter-in-place orders, closures of businesses and schools, fiscal and monetary stimulus, and legislation designed to deliver financial aid and other relief. While the scope, duration, and full effects of COVID-19 continue to evolve and are not fully known, the pandemic and the efforts to contain it have disrupted global economic activity, adversely affected the functioning of financial markets, impacted market interest rates, increased economic and market uncertainty, and disrupted trade and supply chains. Many of the emergency actions taken to mitigate the effects of the pandemic have since been reduced or eliminated, resulting in an improved local and national economic environment, however t he ultimate financial impact of the pandemic on our business is still unknown at this time. The pandemic may continue to adversely impact consumers and several industries within our geographic footprint and impair the ability of the Company’s customers to fulfill their contractual obligations to the Company. This could cause the Company to experience a material adverse effect on our business operations, asset valuations, financial condition, and results of operations. Material adverse impacts may include, but are not limited to, the valuation impairments of the Company’s intangible assets, investments, loans, or deferred tax assets. Additionally, i t is reasonably possible that the Company’s allowance for loan loss estimate as of September 30, 2021 could change in the near term and could result in a material change to the Company’s provision for loan losses, earnings and capital.
Use of Estimates	Use of Estimates
Recent Accounting Pronouncements	The pronouncements discussed below are not intended to be an all-inclusive list, but rather only those pronouncements that the Company has determined could potentially have a material impact on our financial position, results of operations or disclosures. There were no accounting standards adopted in the current period. Future Application of Accounting Pronouncements Previously Issued In June 2016, the FASB issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 affects entities holding financial assets that are not accounted for at fair value through net income, including loans, debt securities, and other financial assets. The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by recording an allowance for current expected credit losses. In October 2019, the FASB unanimously voted to delay the implementation of the standard for three years for certain companies, including small reporting companies (as defined by the SEC), non-SEC public companies and private companies. The Company currently qualifies as a small reporting company and is subject to the delayed implementation. Therefore, t he amendments in this update will be effective for the Company for the fiscal year beginning on July 1, 2023, including interim periods within that fiscal year. The Company is actively working through the provisions of the Update. Management has established a steering committee which is identifying the methodologies and the additional data requirements necessary to implement the Update and has engaged a third-party software service provider to assist in the Company's implementation. Management is currently evaluating the impact that ASU 2016-13 will have on the Company’s consolidated financial position, results of operations and disclosures.
