Accounting Policies [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Nature of Operations : PCSB Financial Corporation (the “Holding Company” and together with its direct and indirect subsidiaries, the “Company”) is a Maryland corporation organized by PCSB Bank (the “Bank”) for the purpose of acquiring all of the capital stock of the Bank issued in the Bank's conversion to stock ownership on April 20, 2017. At September 30, 2022, the significant assets of the Holding Company were the capital stock of the Bank, cash deposited in the Bank, and a loan to the PCSB Bank Employee Stock Ownership Plan (“ESOP”). The liabilities of the Holding Company were insignificant. The Company is subject to the financial reporting requirements of the Securities Exchange Act of 1934, as amended, and regulation and examination by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) and the New York State Department of Financial Services (the “NYSDFS”). 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 have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), and include the accounts of the Holding Company, the Bank and the Bank's two subsidiaries – PCSB Funding Corp. and UpCounty Realty Corp. (formerly PCSB Realty Ltd.). PCSB Funding Corp. is a real estate investment trust that holds certain mortgage assets. UpCounty Realty Corp. is a corporation that holds certain properties foreclosed upon by the Bank. All intercompany transactions and balances have been eliminated in consolidation. 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 fiscal year ended June 30, 2022, included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2022. Certain prior period amounts have been reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or equity. Risks and Uncertainties: In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events, such as continued interest rate volatility, prolonged periods of inflation, continued trade and supply chain disruptions, economic recession and increased unemployment. Such conditions 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 receivable, or deferred tax assets. Additionally, i t is reasonably possible that the Company’s allowance for loan loss estimate as of September 30, 2022 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 : To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

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 its consolidated financial position and results of operations or on its disclosures. There were no accounting standards adopted in the current period. Future Application of Accounting Pronouncements Previously Issued In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 which 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, the 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. On March 31, 2022 the FASB issued ASU 2022-02 "Financial Instruments - Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures." The ASU eliminates the current accounting guidance on troubled debt restructurings ("TDRs") for creditors, enhances disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty and amends the guidance on vintage disclosures with respect to current period gross charge-offs. For entities that have not yet adopted ASU 2016-13, the amendments in ASU 2022-02 are effective upon the adoption of ASU 2016-13. Management is currently evaluating the impact that ASU 2016-13 and ASU 2022-02 will have on the Company’s consolidated financial position, results of operations and disclosures. The FASB issued ASU 2020-04 “Reference Rate Reform” and ASU 2021-01 “Reference Rate Reform Scope” which collectively address accounting considerations related to the expected discontinuation of LIBOR as a reference rate for financial contracts. These Updates provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). They include optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables), were not substantial (assets within the scope of ASC 470, Debt) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases, and other Topics) of the existing contract. They also include optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. The Updates also allow for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The guidance in these ASUs are effective as of March 12, 2020 through December 31, 2022. The Company has not yet elected to apply the practical expedients contained in these Updates and does not expect significant impact to the consolidated financial statements upon adoption.

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, 2022 or June 30, 2022. Management believes the unrealized losses are primarily a result of changes in market 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, 2022 or June 30, 2022.

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. The following tables present the aging of the recorded investment in past due loans by portfolio segment as of September 30, 2022 and June 30, 2022 (in thousands): September 30, 2022 30-59 60-89 90 Days or Days Past Days Past More Past Total Past Due Due Due Due Current Total Residential mortgages $ - $ 104 $ 427 $ 531 $ 214,055 $ 214,586 Commercial mortgages - - - - 953,539 953,539 Construction - - 2,792 2,792 22,515 25,307 Commercial loans - 51 533 584 141,318 141,902 Home equity lines of credit - - 296 296 22,659 22,955 Consumer and overdrafts - - - - 508 508 Total $ - $ 155 $ 4,048 $ 4,203 $ 1,354,594 $ 1,358,797 June 30, 2022 30-59 60-89 90 Days or Days Past Days Past More Past Total Past Due Due Due Due Current Total Residential mortgages $ - $ - $ 367 $ 367 $ 213,800 $ 214,167 Commercial mortgages - - 1,197 1,197 940,933 942,130 Construction - - 1,113 1,113 19,783 20,896 Commercial loans - 16 400 416 135,888 136,304 Home equity lines of credit - - 399 399 23,289 23,688 Consumer and overdrafts - - 39 39 555 594 Total $ - $ 16 $ 3,515 $ 3,531 $ 1,334,248 $ 1,337,779 Troubled Debt Restructurings The terms of certain loans have been modified as troubled debt restructurings (“TDRs”). 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 both September 30, 2022 and June 30, 2022, the Company had 9 loans, classified as TDRs totaling $ 1.4 million, including $ 1.2 million of loans still accruing interest. The Company has allocated $ 111,000 and $ 119,000 , respectively, of specific reserves to customers whose loan terms have been modified in TDRs as of September 30, 2022 and June 30, 2022. As of September 30, 2022, the Company has no commitments to lend additional funds to customers with outstanding loans that are classified as TDRs. The Company did no t modify any loans during the three months ended September 30, 2022 or 2021 that were classified as TDRs. There were no defaults of TDRs occurring in the three months ended September 30, 2022 or 2021 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. This extension expired as of January 1, 2022 . 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, 2022, no loan payment deferrals were granted or extended by the Company. During the three months ended September 30, 2021, the Company granted or extended loan payment deferrals for 5 residential 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 TDRs. The Company had no loans on loan payment deferral as of September 30, 2022 nor June 30, 2022. 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, 2022 Pass Special Substandard Total Residential mortgages $ 213,581 $ 383 $ 622 $ 214,586 Commercial mortgages 944,482 1,538 7,519 953,539 Construction 22,515 1,679 1,113 25,307 Commercial loans 141,295 145 462 141,902 Home equity lines of credit 22,587 - 368 22,955 Consumer and overdrafts 508 - - 508 Total $ 1,344,968 $ 3,745 $ 10,084 $ 1,358,797 June 30, 2022 Pass Special Substandard Total Residential mortgages $ 212,810 $ 154 $ 1,203 $ 214,167 Commercial mortgages 931,178 1,548 9,404 942,130 Construction 18,104 1,679 1,113 20,896 Commercial loans 135,725 156 423 136,304 Home equity lines of credit 23,220 43 425 23,688 Consumer and overdrafts 594 - - 594 Total $ 1,321,631 $ 3,580 $ 12,568 $ 1,337,779 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, 2022 and June 30, 2022 is as follows (in thousands): September 30, June 30, 2022 2022 Residential mortgages $ 218 $ 221 Commercial mortgages 850 859 Home equity lines of credit 86 89 Carrying amount, net of allowance of $ 0 $ 1,154 $ 1,169 There was no provision for loan losses on purchased credit impaired loans during the three months ended September 30, 2022 or 2021.

Retirement Benefits [Abstract]
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. On February 15, 2017, the Board of Directors approved the freezing of the defined benefit pension plan effective May 1, 2017 . 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. Net periodic benefit cost and other amounts recognized in other comprehensive income for the three months ended September 30, 2022 and 2021 (in thousands): Three Months Ended Three Months Ended September 30, 2022 September 30, 2021 Defined Supplemental Defined Supplemental Service cost $ - $ 82 $ - $ 131 Interest cost 196 26 149 17 Expected return on plan assets ( 410 ) - ( 510 ) - Amortization of prior net loss 141 20 38 16 Settlement charges - - - - Net periodic (benefit) cost $ ( 73 ) $ 128 $ ( 323 ) $ 164 The Company made no contributions to the defined benefit plan during the three months ended September 30, 2022. Employee Stock Ownership Plan On January 1, 2017, the Company established an Employee Stock Ownership Plan (“ESOP”) to provide eligible employees the opportunity to own Company stock. The ESOP is a tax-qualified retirement plan for the benefit of Company employees. On April 20, 2017, the Holding Company granted a loan to the ESOP in the amount of $ 14.5 million for the purchase of 1,453,209 shares of the Company’s common stock at a price of $ 10.00 per share. The loan obtained by the ESOP from the Holding Company to purchase the common stock is payable annually over 15 years at a rate per annum equal to the Prime Rate, reset annually on January 1st ( 3.25 % for 2022). Loan payments are principally funded by cash contributions from the Bank. The loan is secured by the shares purchased, which are held in a suspense account for allocation among participants as the loan is repaid. The balance of the ESOP loan at September 30, 2022 was $ 9.7 million. Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits. The number of shares committed to be released annually is 96,881 through 2032. Dividends on allocated shares increase participant accounts and are used to purchase additional shares of stock. Participants receive the shares at the end of employment. Shares held by the ESOP include the following (Dollars in thousands): September 30, 2022 June 30, 2022 Allocated to participants 541,097 518,371 Unearned 896,348 920,767 Total ESOP shares 1,437,445 1,439,138 Fair value of unearned shares $ 16,072 $ 17,577 Total compensation expense recognized in connection with the ESOP for the three months ended September 30, 2022 and 2021 was $ 467,000 and $ 446,000 , respectively

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 : The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs), matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs), or a broker's opinion of value (Level 3 inputs). Impaired Loans : The fair value of collateral-dependent impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. Appraisals are generally obtained annually and may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Management performs a review of all appraisals, including any such adjustments. The fair value of uncollateralized or non-collateral-dependent loans are generally based on discounted cash flows which utilize management’s assumption of discount rates and expected future cash flows, resulting in a Level 3 classification. Foreclosed Real Estate : Assets acquired through or instead of loan foreclosure are initially recorded at fair value, less estimated costs to sell, when acquired, establishing a new cost basis. These assets are subsequently accounted for at the lower of cost or fair value, less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. 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. Derivatives : The Company’s derivative assets and liabilities consist of transactions undertaken as part of management’s strategy to manage interest rate risk. The valuation of the Company’s interest rate swaps is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy.

Management believes that as of September 30, 2022 and June 30, 2022, the Bank met all capital adequacy requirements to which it was subject, including the capital conservation buffer. 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 for the three months ended September 30, 2022 and 2021: 2022 2021 (Dollars in thousands, except per share data) Net income applicable to common stock $ 4,776 $ 3,614 Average number of common shares outstanding 15,122,732 15,342,975 Less: Average unallocated ESOP shares ( 908,419 ) ( 1,005,432 ) Average number of common shares outstanding used to calculate basic earnings per common share 14,214,313 14,337,543 Effect of equity-based awards 87,287 68,273 Average number of common shares outstanding used to calculate diluted earnings per common share 14,301,600 14,405,816 Earnings per common share: Basic $ 0.34 $ 0.25 Diluted $ 0.33 $ 0.25 Stock options for 1,314,963 and 1,325,935 shares of common stock were not considered in computing diluted earnings per common share for the three months ended September 30, 2022 and 2021, respectively, because they were antidilutive.

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, 2022 and June 30, 2022 (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. Identify the contract with a customer. 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, 2022 2021 Noninterest income: Service charges on deposits $ 234 $ 183 Interchange fees 153 156 Other fees and service charges (1) 66 62 Fees and service charges 453 401 Swap income (1) 141 - Bank-owned life insurance (1) 191 192 Other noninterest income (1) 8 20 Total noninterest income $ 793 $ 613 (1) Not within the scope of ASC 606. 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.

Share-Based Payment Arrangement [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 $ 820,000 and $ 810,000 for the three months ended September 30, 2022 and 2021, 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 726,000 , of which 549,467 shares were granted as of September 30, 2022. The following table presents a summary of RSA activity during the period ended September 30, 2022. Number of Weighted-Average Unvested granted shares outstanding at July 1, 2022 223,450 $ 18.89 Shares granted - - Shares vested ( 2,200 ) 16.21 Shares forfeited - - Unvested granted shares at September 30, 2022 221,250 $ 18.92 As of September 30, 2022, there was $ 2.4 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 1.4 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 period, and have a contractual term of 10 years. The Company has a policy of using shares held as a treasury stock to satisfy share option exercises. Currently, the Company has a sufficient number of treasury shares to satisfy the current level of exercisable share options. 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. Total options available for grant under the Plan are 1,816,511 , of which 1,320,963 options were granted as of September 30, 2022. The following table presents a summary of activity related to stock options granted under the Plan, and changes during the period then ended: Number of Weighted- Weighted- Aggregate (Dollars in thousands, except per share data) Options outstanding at July 1, 2022 1,320,963 $ 18.98 6.4 $ 411 Options granted - - Options expired - - Options forfeited - - Options exercised - - Options outstanding at September 30, 2022 1,320,963 $ 18.98 6.1 $ 37 Exercisable at September 30, 2022 786,578 $ 19.00 6.1 $ 14 As of September 30, 2022, there was $ 1.4 million of total unrecognized compensation cost related to non-vested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 1.4 years.

Leases [Abstract]
Leases	Note 13. Leases As of September 30, 2022, 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 2023 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 9.4 years as of September 30, 2022. 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 2.49 % in determining the lease liability as of September 30, 2022. 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, 2022 or 2021. 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, 2022 or 2021. Total operating lease cost was $ 505,000 for the three months ended September 30, 2022 and 2021, respectively. The right-of-use asset , included in premises and equipment, net, was $ 8.1 million and the corresponding lease liability , included in other liabilities was $ 8.4 million as of September 30, 2022.

The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended June 30, 2022, included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2022. Certain prior period amounts have been reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or equity.
Risks and Uncertainties	Risks and Uncertainties: In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events, such as continued interest rate volatility, prolonged periods of inflation, continued trade and supply chain disruptions, economic recession and increased unemployment. Such conditions 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 receivable, or deferred tax assets. Additionally, i t is reasonably possible that the Company’s allowance for loan loss estimate as of September 30, 2022 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 : To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
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 its consolidated financial position and results of operations or on its disclosures. There were no accounting standards adopted in the current period. Future Application of Accounting Pronouncements Previously Issued In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 which 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, the 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. On March 31, 2022 the FASB issued ASU 2022-02 "Financial Instruments - Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures." The ASU eliminates the current accounting guidance on troubled debt restructurings ("TDRs") for creditors, enhances disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty and amends the guidance on vintage disclosures with respect to current period gross charge-offs. For entities that have not yet adopted ASU 2016-13, the amendments in ASU 2022-02 are effective upon the adoption of ASU 2016-13. Management is currently evaluating the impact that ASU 2016-13 and ASU 2022-02 will have on the Company’s consolidated financial position, results of operations and disclosures. The FASB issued ASU 2020-04 “Reference Rate Reform” and ASU 2021-01 “Reference Rate Reform Scope” which collectively address accounting considerations related to the expected discontinuation of LIBOR as a reference rate for financial contracts. These Updates provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). They include optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables), were not substantial (assets within the scope of ASC 470, Debt) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases, and other Topics) of the existing contract. They also include optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. The Updates also allow for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The guidance in these ASUs are effective as of March 12, 2020 through December 31, 2022. The Company has not yet elected to apply the practical expedients contained in these Updates and does not expect significant impact to the consolidated financial statements upon adoption.
