Basis Of Accounting [Abstract]
Basis of Presentation	Note 1: Basis of Presentation The accompanying unaudited consolidated financial statements of FSB Bancorp, Inc. (“FSB Bancorp”), Fairport Savings Bank (the “Bank”), and its other wholly owned subsidiary, Fairport Wealth Management (collectively, the “Company”), have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions for Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a complete presentation of consolidated financial condition, results of operations and cash flows in conformity with generally accepted accounting principles. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation, have been included. The results are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 or for any future period. The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and follow practices within the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions, and judgments are necessary when assets and liabilities are required to be recorded at fair value or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and information used to record valuation adjustments for certain assets and liabilities are based on quoted market prices or are provided by other third-party sources, when available. When third party information is not available, valuation adjustments are estimated in good faith by management.

Change in Accounting Estimate [Abstract]
Change in Accounting Estimate	Note 2: Change in Accounting Estimate In conjunction with the filing of the 2017 New York State income tax return and based on challenges encountered with respect to the ongoing mortgage recording tax examinations, the Company believes at this time that it is important to record a valuation percentage lower than 0.25% against all mortgage loans eligible for the special additional mortgage recording tax credit and believes that it is appropriate to adjust the outstanding balance of previously recorded special additional mortgage recording tax credits. The Company made this election on September 30, 2018 and its impact was as follows: Income from continuing operations $(159,000) Net Income $(126,000) Net income per share for the three months ended September 30, 2018 $(0.07) Net income per share for the nine months ended September 30, 2018 $(0.06)

Accounting Policies [Abstract]
New Accounting Pronouncements	Note 3: New Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) and subsequent updates. This ASU clarifies the principles for recognizing revenue and develops a common standard for U.S. GAAP and International Financial Reporting Standards. The ASU establishes a core principle that requires an entity to identify the contract(s) with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the entity satisfies a performance obligation. The ASU provides for improved disclosure requirements that require entities to disclose sufficient financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted the guidance effective January 1, 2018 using the modified retrospective method. The Company’s revenue is the sum of net interest income and non-interest income. The scope of the guidance excludes nearly all net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives. The Company completed its review and determined that the majority of non-interest income revenue streams are within the scope of the new standard. Non-interest income streams that are out of scope of the new standard include BOLI, sales of investment securities, mortgage banking activities, and certain items within service charges and other income. Management reviewed contracts related to service charges on deposits, investment advisory commissions and fee income, insurance commission and fee income, and certain items within other service charges and other income. The Company evaluated the impact of this ASU on the Company’s various revenue streams and, upon adoption on January 1, 2018 and going forward, does not anticipate a material impact to the consolidated financial statements. The Company has included applicable disclosures regarding revenue recognition within Note 10 of these consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities. The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update also simplify the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods with those fiscal years. The adoption had no impact on the consolidated financial statements and only impacted fair value measurement disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This new guidance supersedes the lease requirements in Topic 840, Leases and is based on the principle that a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The accounting applied by a lessor is largely unchanged from that applied under the previous guidance. In addition, the guidance requires an entity to separate the lease components from the nonlease components in a contract. The ASU requires disclosures about the amount, timing, and judgments related to a reporting entity's accounting for leases and related cash flows. The standard is required to be applied to all leases in existence as of the date of adoption using a modified retrospective transition approach. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for all companies in any interim or annual period. The Company occupies certain offices and uses certain equipment under non-cancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. The Company expects to recognize lease liabilities and right of use assets associated with these lease agreements; however, the extent of the impact on the Company's consolidated financial statements is currently under evaluation. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326). This new guidance significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. This ASU will replace the "incurred loss" model under existing guidance with an "expected loss" model for instruments measured at amortized cost, and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. This ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. This guidance requires adoption through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for all companies as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the guidance will have on the Company's consolidated financial statements, and expects an increase in the allowance for credit losses resulting from the change to expected losses for the estimated life of the financial asset, including an allowance for debt securities. The amount of the increase in the allowance for credit losses resulting from the new guidance will be impacted by the portfolio composition and asset quality at the adoption date, as well as economic conditions and forecasts at the time of adoption. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). The amendments provide guidance on the following eight specific cash flow issues: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investees; 7) beneficial interests in securitization transactions; and 8) separately identifiable cash flows and application of the predominance principle. This ASU is effective for fiscal years beginning after December 31, 2017, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company adopted the amendment in this update during the three months ended March 31, 2018 and noted no material impact to the consolidated financial statements. In March 2017, the FASB issued an Update (ASU 2017-08) to its guidance on “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20) related to premium amortization on purchased callable debt securities. The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosure about a change in accounting principle. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In May 2018, the FASB issued ASU No. 2018-06, Codification Improvements to Topic 942, Financial Services - Depository and Lending In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU No. 2018-08, Not for Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842. Leases In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements which amends FASB Accounting Standards Codification (ASC) Topic 842, Leases , to (1) add an optional transition method that would permit entities to apply the new requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the year of adoption, and (2) provide a practical expedient for lessors regarding the separation of the lease and non-lease components of a contract. This guidance did not change the Company’s assessment of the impact of ASU No. 2016-02 on the consolidated financial statements as described above. In August 2018, the FASB has issued Accounting Standards Update (ASU) No. 2018-15, Intangibles—Goodwill and Other—Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, a consensus of the FASB Emerging Issues Task Force, which amends the FASB Accounting Standards Codification (ASC) to provide guidance on accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement, which provided guidance to customers concerning whether a cloud computing arrangement (e.g., software, platform, or infrastructure offered as a service) includes a software license. Pursuant to that guidance, (1) if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for in a manner consistent with the acquisition of other software licenses, or (2) if the arrangement does not include a software license, then the arrangement should be accounted for as a service contract, with the fees associated with the hosting element (service) of the arrangement expensed as they are incurred. Following the issuance of ASU No. 2015-05, constituents requested that the FASB provide additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. Accordingly, because United States generally accepted accounting principles (U.S. GAAP) do not contain explicit guidance on accounting for such costs, and to address the resulting diversity in practice, the FASB has issued ASU No. 2018-15 to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Note that the guidance on accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in ASU No. 2018-15. For Public Business Entities, the amended guidance is effective for fiscal years beginning after December 15, 2019 (i.e., calendar-year 2020), and for interim periods within those fiscal years. In October 2018, the FASB issued Accounting Standards Update (ASU) No. 2018-16 , Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes , which adds the SOFR OIS as a benchmark rate that businesses can use to designate hedges of interest rate risk. This update adds to U.S. GAAP a new interest rate from the market for U.S. Treasury repurchase contracts to the list of accepted benchmark rates for hedge accounting. The SOFR is calculated by the Fed based on the interest rates banks charge one another in the overnight market for loans they make to one another, typically called repurchase agreements. In introducing the new rate, the Fed said that because it is based on transactions in the open market, it is more reflective of market conditions than LIBOR, which relies more on judgment. Adding the SOFR OIS as an acceptable hedge accounting benchmark for U.S. GAAP is considered a critical step in helping it gain more acceptance in the market. FASB ASC 815 provides guidance on the risks associated with financial assets or liabilities that are allowed to be hedged. Among those risks is the risk of changes in fair values or cash flows of existing or forecasted issuances or purchases of fixed-rate financial assets or liabilities attributable to a designated benchmark interest rate. U.S. GAAP considers a benchmark rate as a rate that is widely recognized, commonly referenced, and quoted in an active financial market. FASB ASC 815 lists three rates as benchmarks: the rate on direct Treasury obligations of the U.S. government, the Fed Funds Effective Swap Rate (Overnight Index Swap Rate), and the LIBOR swap rate. In 2017, the FASB added a fourth rate, the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate when it published ASU No. 2017-12 , Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which made several other changes to simplify hedge accounting and expand its use. The FASB wants businesses and organizations to adopt the amendments in ASU No. 2018-16 at the same time they adopt the changes in ASU No. 2017-12 .

Earnings Per Share [Abstract]
Earnings per Common Share	Note 4: Earnings per Common Share Basic earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Net income available to common stockholders is net income to FSB Bancorp, Inc. Diluted earnings per share is calculated 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 is no impact on earnings per share because no stock options have vested as of September 30, 2018. On September 27, 2017, the Board of Directors of the Company approved restricted stock and stock option grants to senior management and the directors of the Company, pursuant to the terms of the 2017 Equity Incentive Plan (the “Plan”). The Plan was approved previously by the Company’s stockholders on August 29, 2017. An aggregate of 20,000 stock options and 8,400 shares of restricted stock were granted to senior management during the nine months ended September 30, 2018. The grants to senior management vest over a five year period in equal annual installments, with the first installment vesting on the first anniversary date of the grant and succeeding installments on each anniversary thereafter, through 2023. The Company did not grant any restricted stock awards or stock options during the nine months ended September 30, 2017. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released. The following tables set forth the calculation of basic and diluted earnings per share.

The Company assesses whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the statement of condition date. Under these circumstances, OTTI is considered to have occurred (1) if we intend to sell the security; (2) if it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not anticipated to be sufficient to recover the entire amortized cost basis. The guidance requires that credit-related OTTI is recognized in earnings while non-credit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (“OCI”). Non-credit-related OTTI is based on other factors, including illiquidity and changes in the general interest rate environment. Presentation of OTTI is made in the consolidated statement of income on a gross basis, including both the portion recognized in earnings as well as the portion recorded in OCI. The gross OTTI would then be offset by the amount of non-credit-related OTTI, showing the net as the impact on earnings. There were 35 securities in an unrealized loss position at September 30, 2018, of which 25 have been in loss positions for a period greater than twelve months and 10 have been in loss positions for a period less than twelve months. This compares to 33 securities in an unrealized loss position at December 31, 2017, of which 15 had been in loss positions for a period greater than twelve months and 18 had been in loss positions for a period less than twelve months. These issuing entities are currently rated Aaa by Moody’s Investor Services and AA+ by Standard and Poors. Among the 25 securities in loss positions for a period greater than twelve months at September 30, 2018, 13 were either direct issuances of, or mortgage-backed securities or collateralized mortgage obligations issued by, the following entities sponsored and guaranteed by the United States Government: GNMA, FNMA, and FHLMC. The remaining 12 securities that have been in a loss position for a period greater than twelve months were issued by a state or political subdivision, primarily local municipalities. The unrealized losses reflected are primarily attributable to changes in interest rates since the securities were acquired. Among the 10 securities in an unrealized loss position at September 30, 2018 for less than twelve months, one was a direct issuance of FHLB and guaranteed by the United States Government. The remaining nine securities were issued by a state or political subdivision, primarily local municipalities. The unrealized losses reflected are primarily attributable to changes in interest rates since the securities were acquired. The Company does not intend to sell these securities, nor is it more likely than not, that the Company will be required to sell these securities prior to recovery of the amortized cost. The state and municipal securities are general obligation (G.O.) bonds backed by the full faith and credit of local municipalities. There has never been a default of a New York G.O. in the history of the state. Historical performance does not guarantee future performance, but it does indicate that the risk of loss on default of a G.O. municipal bond for the Company is relatively low. All are paying in accordance with their terms with no deferrals of interest or defaults. As such, management does not believe any individual unrealized loss as of September 30, 2018 represents OTTI. There were no realized gains or losses on sales of securities for the three or nine months ended September 30, 2018 and September 30, 2017. As of September 30, 2018 and December 31, 2017, no securities were pledged to secure public deposits or for any other purpose required or permitted by law. Management has reviewed its loan and mortgage-backed securities portfolios and determined that, to the best of its knowledge, little or no exposure exists to sub-prime or other high-risk residential mortgages. The Company is not in the practice of investing in, or originating, these types of investments or loans.

Although the Company has a diversified loan portfolio, a substantial portion of its borrowers’ abilities to honor their loan contracts is dependent upon the counties’ employment and economic conditions. As of September 30, 2018 and December 31, 2017, residential mortgage loans with a carrying value of $194.9 million and $190.4 million, respectively, have been pledged by the Company to the Federal Home Loan Bank of New York (“FHLBNY”) under a blanket collateral agreement to secure the Company’s line of credit and term borrowings. The Company retains the servicing on conventional fixed-rate mortgage loans sold to Freddie Mac (“FHLMC”) and receives a fee based on the principal balance outstanding. Loans serviced for others totaled $126.5 million and $132.4 million at September 30, 2018 and December 31, 2017, respectively. Loan servicing rights are recorded at fair value when loans are sold with servicing rights retained. The fair value of the mortgage servicing rights (“MSRs”) is determined using a method which utilizes servicing income, discount rates, and prepayment speeds relative to the Bank’s portfolio for MSRs and are amortized over the life of the loan. MSRs amounted to $848,000 and $892,000 at September 30, 2018 and December 31, 2017, respectively, and are included in other assets on the consolidated balance sheets. Loan Origination / Risk Management The Company’s lending policies and procedures are presented in Note 4 to the consolidated financial statements included in FSB Bancorp’s Amendment No. 1 to the Annual Report on Form 10-K/A filed with the Securities and Exchange Commission on August 13, 2018 and have not changed. To develop and document a systematic methodology for determining the allowance for loan losses, the Company has divided the loan portfolio into two portfolio segments, each with different risk characteristics but with similar methodologies for assessing risk. Each portfolio segment is broken down into loan classes where appropriate. Loan classes contain unique measurement attributes, risk characteristics, and methods for monitoring and assessing risk that are necessary to develop the allowance for loan losses. Unique characteristics such as borrower type, loan type, collateral type, and risk characteristics define each class. The following table illustrates the portfolio segments and classes for the Company’s loan portfolio: Portfolio Segment Class Real Estate Loans Secured by one-to-four family residences Secured by multi-family residences Construction Commercial real estate Home equity lines of credit Other Loans Commercial and industrial Other loans The following tables present the classes of the loan portfolio, not including net deferred loan fees, summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company's internal risk rating system as of the dates indicated: As of September 30, 2018 Special (In thousands) Pass Mention Substandard Doubtful Total Real estate loans: Secured by one-to-four family residences $ 216,176 $ 500 $ 3,165 $ - $ 219,841 Secured by multi-family residences 10,337 - - - 10,337 Construction 6,277 - - - 6,277 Commercial real estate 20,462 1,188 - - 21,650 Home equity lines of credit 16,808 - 204 - 17,012 Total real estate loans 270,060 1,688 3,369 - 275,117 Commercial & industrial loans 5,354 - 45 - 5,399 Other loans 56 - - - 56 Total loans $ 275,470 $ 1,688 $ 3,414 $ - $ 280,572 As of December 31, 2017 Special (In thousands) Pass Mention Substandard Doubtful Total Real estate loans: Secured by one-to-four family residences $ 203,815 $ 116 $ 2,963 $ - $ 206,894 Secured by multi-family residences 10,650 - - - 10,650 Construction 10,750 - - - 10,750 Commercial real estate 14,803 - - - 14,803 Home equity lines of credit 16,897 - 230 - 17,127 Total real estate loans 256,915 116 3,193 - 260,224 Commercial & industrial loans 3,679 - - - 3,679 Other loans 70 - - - 70 Total loans $ 260,664 $ 116 $ 3,193 $ - $ 263,973 Real estate loans secured by one-to four family residences rated substandard increased $202,000, or 6.8%, to $3.2 million at September 30, 2018 from $3.0 million at December 31, 2017 due to the addition of 10 residential mortgage loans newly categorized as substandard at September 30, 2018, partially offset by the upgrades of six residential mortgage loans now paying as agreed and three mortgage loan payoffs. Real estate loans secured by one-to four family residences rated special mention increased $384,000, or 330.2%, to $500,000 at September 30, 2018 from $116,000 at December 31, 2017 due to the addition of one residential mortgage loan newly categorized as special mention at September 30, 2018, partially offset by one loan now being paid as agreed which was classified as special mention at December 31, 2017. Commercial real estate loans rated special mention increased $1.2 million to $1.2 million from the $0 balance at December 31, 2017 due to the addition of three loans newly categorized as special mention after annual financial statement reviews of these borrowers were performed during the nine months ended September 30, 2018. Commercial and industrial loans rated substandard increased $45,000 to $45,000 from the $0 balance at December 31, 2017 due to the addition of one loan newly categorized as substandard during the nine months ended September 30, 2018. Management has reviewed its loan portfolio and determined that, to the best of its knowledge, no exposure exists to sub-prime or other high-risk residential mortgages. The Company is not in the practice of originating these types of loans. Nonaccrual and Past Due Loans Loans are placed on nonaccrual when the contractual payment of principal and interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may be currently performing. Loans are considered past due if the required principal and interest payments have not been received within thirty days of the payment due date. An age analysis of past due loans, segregated by portfolio segment and class of loans, as of September 30, 2018 and December 31, 2017, are detailed in the following tables: As of September 30, 2018 30-59 Days 60-89 Days Past Due Past Due 90 Days Total Total Loans (In thousands) And Accruing And Accruing and Over Past Due Current Receivable Real estate loans: Secured by one-to-four family residences $ 1,150 $ - $ 55 $ 1,205 $ 218,636 $ 219,841 Secured by multi-family residences - - - - 10,337 10,337 Construction - - - - 6,277 6,277 Commercial - - - - 21,650 21,650 Home equity lines of credit 5 - - 5 17,007 17,012 Total real estate loans 1,155 - 55 1,210 273,907 275,117 Commercial & industrial loans - - 45 45 5,354 5,399 Other loans - - - - 56 56 Total loans $ 1,155 $ - $ 100 $ 1,255 $ 279,317 $ 280,572 As of December 31, 2017 30-59 Days 60-89 Days Past Due Past Due 90 Days Total Total Loans (In thousands) And Accruing And Accruing and Over Past Due Current Receivable Real estate loans: Secured by one-to-four family residences $ 699 $ - $ 153 $ 852 $ 206,042 $ 206,894 Secured by multi-family residences - - - - 10,650 10,650 Construction - - - - 10,750 10,750 Commercial - - - - 14,803 14,803 Home equity lines of credit - - - - 17,127 17,127 Total real estate loans 699 - 153 852 259,372 260,224 Commercial & industrial loans - - - - 3,679 3,679 Other loans - - - - 70 70 Total loans $ 699 $ - $ 153 $ 852 $ 263,121 $ 263,973 Real estate loans secured by one-to four family residences 30-59 days past due and accruing increased $451,000, or 64.5%, to $1.2 million at September 30, 2018 from $699,000 at December 31, 2017 due to the delinquency of three additional mortgage loans during the nine months ended September 30, 2018, partially offset by two mortgage loan payoffs. At September 30, 2018, the Company had one nonaccrual residential mortgage loan for $55,000 and one nonaccrual commercial and industrial loan for $45,000. At December 31, 2017, the Company had two nonaccrual residential mortgage loans for $153,000.

Fair Value Measurements

Fair Value Measurements	9 Months Ended
	Sep. 30, 2018
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8: Fair Value Measurements Accounting guidance related to fair value measurements and disclosures specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair value hierarchy: 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 – Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 3 – Model-derived valuations in which one or more significant inputs or significant value drivers are unobservable. 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. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs, minimize the use of unobservable inputs, to the extent possible, and considers counterparty credit risk in its assessment of fair value. The following tables summarize assets measured at fair value on a recurring basis as of the indicated dates, segregated by the level of valuation inputs within the hierarchy utilized to measure fair value: September 30, 2018 (In thousands) Level 1 Level 2 Level 3 Total Fair Value Available-for-sale portfolio U.S. Government and agency obligations $ - $ 10,855 $ - $ 10,855 Mortgage-backed securities – residential - 6,172 - 6,172 Total available-for-sale securities $ - $ 17,027 $ - $ 17,027 December 31, 2017 (In thousands) Level 1 Level 2 Level 3 Total Fair Value Available-for-sale portfolio U.S. Government and agency obligations $ - $ 10,470 $ - $ 10,470 Mortgage-backed securities – residential - 7,843 - 7,843 Total available-for-sale securities $ - $ 18,313 $ - $ 18,313 There have been no transfers of assets into or out of any fair value measurement level during the nine months ended September 30, 2018. Required disclosures include fair value information of financial instruments, whether or not recognized in the consolidated statement of condition, for which it is practicable to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The Company has various processes and controls in place to ensure that fair value is reasonably estimated. The Company performs due diligence procedures over third-party pricing service providers in order to support their use in the valuation process. While the Company believes its valuation methods are appropriate and consistent with other market participants, 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. 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 as of their respective period-ends, and have not been re-evaluated or updated for purposes of these 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. FASB ASC Topic 820 for Fair Value Measurements and Disclosures, the financial assets and liabilities were valued at a price that represents the Company’s exit price or the price at which these instruments would be sold or transferred. 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 Company, in estimating its fair value disclosures for financial instruments, used the following methods and assumptions: Cash, Due from Banks, and Interest Earning Demand Deposits The carrying amounts of these assets approximate their fair values. Investment Securities The fair value of securities available for sale (carried at fair value) and held to maturity (carried at amortized cost) are determined by matrix pricing, 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 relying on the securities’ relationship to other benchmark quoted prices and is considered to be a Level 2 measurement. Investment in Restricted Stock The carrying value of restricted stock, which consists of Federal Home Loan Bank and Atlantic Community Bankers Bank, approximates its fair value based on the redemption provisions of the restricted stock, resulting in a Level 2 classification. Loans The fair values of loans held in portfolio are estimated using discounted cash flow analyses, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the loans, resulting in a Level 3 classification. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal. Generally, for variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Loans held for sale in the secondary market are carried at the lower of cost or fair value, resulting in a Level 2 classification. Separate determinations of fair value for residential and commercial loans are made on an aggregate basis. Fair value is determined based solely on the effect of changes in secondary market interest rates and yield requirements from the commitment date to the date of the financial statements. Accrued Interest Receivable and Payable The carrying amount of accrued interest receivable and payable approximates fair value. Deposits The fair values disclosed for demand deposits (e.g., NOW accounts, non-interest checking, regular savings and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts), resulting in a Level 1 classification. The carrying amounts for variable-rate certificates of deposit approximate their fair values at the reporting date, resulting in a Level 1 classification. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits, resulting in a Level 2 classification. Borrowings The fair values of FHLB long-term borrowings are estimated using discounted cash flow analyses, based on the quoted rates for new FHLB advances with similar credit risk characteristics, terms and remaining maturity, resulting in a Level 2 classification. The carrying amounts and fair values of the Company’s financial instruments as of the indicated dates are presented in the following table: September 30, 2018 December 31, 2017 Fair Value Carrying Estimated Carrying Estimated (In thousands) Hierarchy Amounts Fair Values Amounts Fair Values Financial assets: Cash and due from banks 1 $ 1,648 $ 1,648 $ 1,672 $ 1,672 Interest earning demand deposits 1 4,317 4,317 8,725 8,725 Securities - available-for-sale 2 17,027 17,027 18,313 18,313 Securities - held-to-maturity 2 6,335 6,265 6,575 6,588 Investment in restricted stock 2 3,725 3,725 3,270 3,270 Loans held for sale 2 4,662 4,662 2,770 2,770 Loans, net 3 279,065 274,943 262,711 261,588 Accrued interest receivable 1 936 936 824 824 Financial liabilities: Demand Deposits, Savings, NOW and MMDA 1 102,730 102,730 103,377 103,377 Time Deposits 2 116,654 116,657 113,314 113,501 Borrowings 2 73,796 74,348 64,447 64,502 Accrued interest payable 1 156 156 94 94

Stock-Based Compensation	Note 11: Stock-Based Compensation On January 5, 2018, a total of 6,400 restricted stock awards were granted to four executive officers of the Company. On July 2, 2018, a total of 2,000 restricted stock awards were granted to one executive officer of the Company. The awards will vest ratably over five years (20% per year for each year of the participant’s service with the Company). The Company has a stock-based compensation plan which allows the Company to issue up to 194,168 stock options. On January 5, 2018, the Board of Directors granted a combined total of 15,000 options to three executive officers to buy stock under the plan at an exercise price of $17.52, the fair value of the stock as of January 5, 2018. On July 2, 2018, the Board of Directors granted a total of 5,000 options to one executive officer to buy stock under the plan at an exercise price of $17.75, the fair value of the stock as of July 2, 2018. These options have a 10-year term and are vested over a five year period (20% per year for each year of the participant’s service with the Company). A summary of the Company’s stock option activity and related information for its option plans for the three and nine months ended September 30, 2018 is as follows: For the three months ended For the nine months ended Options Weighted Average Options Weighted Average Outstanding at beginning of period 167,080 $ 16.79 152,080 $ 16.72 Grants 5,000 17.75 20,000 17.58 Exercised - - - - Outstanding at quarter end 172,080 $ 16.82 172,080 $ 16.82 Exercisable at quarter end - $ - - $ - The Company did not grant any stock options for the three and nine months ended September 30, 2017.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements of FSB Bancorp, Inc. (“FSB Bancorp”), Fairport Savings Bank (the “Bank”), and its other wholly owned subsidiary, Fairport Wealth Management (collectively, the “Company”), have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions for Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a complete presentation of consolidated financial condition, results of operations and cash flows in conformity with generally accepted accounting principles. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation, have been included. The results are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 or for any future period. The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and follow practices within the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions, and judgments are necessary when assets and liabilities are required to be recorded at fair value or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and information used to record valuation adjustments for certain assets and liabilities are based on quoted market prices or are provided by other third-party sources, when available. When third party information is not available, valuation adjustments are estimated in good faith by management.
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) and subsequent updates. This ASU clarifies the principles for recognizing revenue and develops a common standard for U.S. GAAP and International Financial Reporting Standards. The ASU establishes a core principle that requires an entity to identify the contract(s) with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the entity satisfies a performance obligation. The ASU provides for improved disclosure requirements that require entities to disclose sufficient financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted the guidance effective January 1, 2018 using the modified retrospective method. The Company’s revenue is the sum of net interest income and non-interest income. The scope of the guidance excludes nearly all net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives. The Company completed its review and determined that the majority of non-interest income revenue streams are within the scope of the new standard. Non-interest income streams that are out of scope of the new standard include BOLI, sales of investment securities, mortgage banking activities, and certain items within service charges and other income. Management reviewed contracts related to service charges on deposits, investment advisory commissions and fee income, insurance commission and fee income, and certain items within other service charges and other income. The Company evaluated the impact of this ASU on the Company’s various revenue streams and, upon adoption on January 1, 2018 and going forward, does not anticipate a material impact to the consolidated financial statements. The Company has included applicable disclosures regarding revenue recognition within Note 10 of these consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities. The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update also simplify the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods with those fiscal years. The adoption had no impact on the consolidated financial statements and only impacted fair value measurement disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This new guidance supersedes the lease requirements in Topic 840, Leases and is based on the principle that a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The accounting applied by a lessor is largely unchanged from that applied under the previous guidance. In addition, the guidance requires an entity to separate the lease components from the nonlease components in a contract. The ASU requires disclosures about the amount, timing, and judgments related to a reporting entity's accounting for leases and related cash flows. The standard is required to be applied to all leases in existence as of the date of adoption using a modified retrospective transition approach. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for all companies in any interim or annual period. The Company occupies certain offices and uses certain equipment under non-cancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. The Company expects to recognize lease liabilities and right of use assets associated with these lease agreements; however, the extent of the impact on the Company's consolidated financial statements is currently under evaluation. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326). This new guidance significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. This ASU will replace the "incurred loss" model under existing guidance with an "expected loss" model for instruments measured at amortized cost, and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. This ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. This guidance requires adoption through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for all companies as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the guidance will have on the Company's consolidated financial statements, and expects an increase in the allowance for credit losses resulting from the change to expected losses for the estimated life of the financial asset, including an allowance for debt securities. The amount of the increase in the allowance for credit losses resulting from the new guidance will be impacted by the portfolio composition and asset quality at the adoption date, as well as economic conditions and forecasts at the time of adoption. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). The amendments provide guidance on the following eight specific cash flow issues: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investees; 7) beneficial interests in securitization transactions; and 8) separately identifiable cash flows and application of the predominance principle. This ASU is effective for fiscal years beginning after December 31, 2017, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company adopted the amendment in this update during the three months ended March 31, 2018 and noted no material impact to the consolidated financial statements. In March 2017, the FASB issued an Update (ASU 2017-08) to its guidance on “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20) related to premium amortization on purchased callable debt securities. The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosure about a change in accounting principle. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In May 2018, the FASB issued ASU No. 2018-06, Codification Improvements to Topic 942, Financial Services - Depository and Lending In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU No. 2018-08, Not for Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842. Leases In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements which amends FASB Accounting Standards Codification (ASC) Topic 842, Leases , to (1) add an optional transition method that would permit entities to apply the new requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the year of adoption, and (2) provide a practical expedient for lessors regarding the separation of the lease and non-lease components of a contract. This guidance did not change the Company’s assessment of the impact of ASU No. 2016-02 on the consolidated financial statements as described above. In August 2018, the FASB has issued Accounting Standards Update (ASU) No. 2018-15, Intangibles—Goodwill and Other—Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, a consensus of the FASB Emerging Issues Task Force, which amends the FASB Accounting Standards Codification (ASC) to provide guidance on accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement, which provided guidance to customers concerning whether a cloud computing arrangement (e.g., software, platform, or infrastructure offered as a service) includes a software license. Pursuant to that guidance, (1) if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for in a manner consistent with the acquisition of other software licenses, or (2) if the arrangement does not include a software license, then the arrangement should be accounted for as a service contract, with the fees associated with the hosting element (service) of the arrangement expensed as they are incurred. Following the issuance of ASU No. 2015-05, constituents requested that the FASB provide additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. Accordingly, because United States generally accepted accounting principles (U.S. GAAP) do not contain explicit guidance on accounting for such costs, and to address the resulting diversity in practice, the FASB has issued ASU No. 2018-15 to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Note that the guidance on accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in ASU No. 2018-15. For Public Business Entities, the amended guidance is effective for fiscal years beginning after December 15, 2019 (i.e., calendar-year 2020), and for interim periods within those fiscal years. In October 2018, the FASB issued Accounting Standards Update (ASU) No. 2018-16 , Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes , which adds the SOFR OIS as a benchmark rate that businesses can use to designate hedges of interest rate risk. This update adds to U.S. GAAP a new interest rate from the market for U.S. Treasury repurchase contracts to the list of accepted benchmark rates for hedge accounting. The SOFR is calculated by the Fed based on the interest rates banks charge one another in the overnight market for loans they make to one another, typically called repurchase agreements. In introducing the new rate, the Fed said that because it is based on transactions in the open market, it is more reflective of market conditions than LIBOR, which relies more on judgment. Adding the SOFR OIS as an acceptable hedge accounting benchmark for U.S. GAAP is considered a critical step in helping it gain more acceptance in the market. FASB ASC 815 provides guidance on the risks associated with financial assets or liabilities that are allowed to be hedged. Among those risks is the risk of changes in fair values or cash flows of existing or forecasted issuances or purchases of fixed-rate financial assets or liabilities attributable to a designated benchmark interest rate. U.S. GAAP considers a benchmark rate as a rate that is widely recognized, commonly referenced, and quoted in an active financial market. FASB ASC 815 lists three rates as benchmarks: the rate on direct Treasury obligations of the U.S. government, the Fed Funds Effective Swap Rate (Overnight Index Swap Rate), and the LIBOR swap rate. In 2017, the FASB added a fourth rate, the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate when it published ASU No. 2017-12 , Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which made several other changes to simplify hedge accounting and expand its use. The FASB wants businesses and organizations to adopt the amendments in ASU No. 2018-16 at the same time they adopt the changes in ASU No. 2017-12 . For public companies that have adopted ASU No. 2017-12, the new amendments are effective for fiscal years beginning after December 15 and interim periods within those fiscal years. For other companies and organizations that already have adopted ASU No. 2017-12 , the new amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted in any interim period as long as the company or organization already has adopted the broader 2017 hedge accounting update.
