Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations: TC Bancshares, Inc. ("Company") is a savings and loan holding company incorporated under the laws of the State of Georgia in 2021, to serve as the holding company for TC Federal Bank ("Bank"). The Company owns 100 % of the outstanding stock of the Bank. See Note 13 for a detailed discussion of the Company. The Bank was organized in 1934 and chartered in 1937 by the Federal Home Loan Bank Board as a mutual savings and loan association owned 100% by its depositors. The Bank operates one branch in Thomasville, Georgia, and one in Tallahassee, Florida as well as loan production offices in Tallahassee, Florida and Savannah, Georgia, that provide a variety of services to individuals and corporate customers in their markets. The Bank’s primary deposit products are interest-bearing checking accounts, savings accounts, and certificates of deposit. Its primary lending products consist of single-family residential mortgage loans and commercial and multi-family real estate loans. The Bank is regulated by the Office of the Comptroller of the Currency (“OCC”) and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). The Bank undergoes periodic examinations by the OCC. The Company is subject to the supervision, examination, and reporting requirements of the Bank Holding Company Act and the regulations of the Board of Governors of the Federal Reserve System (the "Federal Reserve"). Basis of Presentation: The accounting and financial reporting policies of the Company and the Bank conform, in all material respects to accounting principles generally accepted in the United States of America (“GAAP”) and with general practices within the banking industry. The consolidated financial statements have been prepared in accordance with GAAP and with the instructions to Form 10-K adopted by the Securities and Exchange Commission (the “SEC”). In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ significantly from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of the post-retirement obligation, and valuation allowance associated with the realization of deferred tax assets, which are based on future taxable income. In 2020, Coronavirus Disease 2019 (COVID-19) spread into a worldwide pandemic. The pandemic may impact various parts of the Company’s future operations and financial results, including additional allowance for loan loss provisions. Management believes the Company is taking appropriate actions to mitigate the negative impact. However, the full impact of COVID-19 on the allowance for loan losses as of December 31, 2021 cannot be reasonably estimated, as these events are still developing. Cash and Cash Equivalents: For purposes of reporting cash flows, cash and cash equivalents include cash and balances due from banks and federal funds sold, all of which mature within 90 days. Reserve requirements held in cash on hand or in deposit with the Federal Reserve Bank of Atlanta by the Company were $ 0 at December 31, 2021 and 2020. Investment Securities: The Company classifies its securities in one of three categories: trading, available-for-sale, or held-to-maturity. Trading securities are bought and held principally for the purpose of selling them in the near term. Held-to-maturity securities are those securities for which the Company has the ability and intent to hold the security until maturity. All other securities not included in trading or held-to-maturity are classified as available-for-sale. As of December 31, 2021 and 2020, all securities were classified as available-for-sale. Trading and available-for-sale securities are recorded at fair value. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization of premiums and accretion of discounts. Unrealized holding gains and losses, net of the related tax effect, on securities available-for-sale are excluded from income and are reported as a separate component of accumulated other comprehensive income in shareholders’ equity until realized. Transfers of securities between categories are recorded at fair value at the date of transfer. Management evaluates investment securities for other-than-temporary impairment on an annual basis. A decline in the market value of any investment below cost that is deemed other-than-temporary is charged to income for the decline in value deemed to be credit related and a new cost basis in the security is established. The decline in value attributed to non-credit related factors is recognized in other comprehensive income. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to the yield. Realized gains and losses for securities classified as available-for-sale are included in income and are derived using the specific identification method for determining the cost of securities sold. Other Investments: Other investments are carried at cost and consist of Federal Home Loan Bank of Atlanta (“FHLB”) stock. The Bank is required to hold the FHLB stock as a member of the FHLB, and transfer of the stock is substantially restricted. The stock is pledged as collateral for outstanding FHLB advances. Loans, Loan Fees and Interest Income on Loans: Loans are stated at the principal amount outstanding, net of the allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions and collection efforts that the borrower’s financial condition is such that collection of interest is doubtful. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is charged to interest income on loans. Generally, payments on nonaccrual loans are applied to principal. Loan fees, net of certain origination costs, are deferred and amortized over the lives of the respective loans. A loan is impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or at the loan’s observable market price, or at the fair value of the collateral of the loan if the loan is collateral dependent. Estimated impairment losses for collateral dependent loans are set up as specific reserves. Interest income on impaired loans is recognized using the cash-basis method of accounting during the time the loans are impaired. Allowance for Loan Losses: The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The allowance represents an amount which, in management’s judgment based on, among other things, historical losses and on the current economic environment, will be adequate to absorb probable losses on existing loans that may become uncollectible. Loans deemed uncollectible are charged-off and deducted from the allowance and recoveries on loans previously charged-off are added back to the allowance. Management’s judgment in determining the adequacy of the allowance is based on evaluations of the collectability of loans. These evaluations take into consideration such factors as changes in the nature and volume of the loan portfolio, current economic conditions that may affect the borrower’s ability to pay, overall portfolio quality, and review of specific problem loans. Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. As a result of such review, the Bank may have to recognize additions to its allowance for loan losses. Mortgage Loans Held for Sale: The Bank sells mortgage loans for an amount equal to the principal amount of loans with yields to investors based upon current market rates. Realized gains and losses related to loan sales are included in gains on sale of loans and are determined using the specific identification method. For financial reporting purposes, the Bank classifies a portion of its loans as “Mortgage loans held for sale”. Included in this category are loans which the Bank has the current intent to sell and loans which are available to be sold in the event the Bank determines that loans should be sold to support the Bank’s investment and liquidity objectives. Loans included in this category for which the Bank has the current intention to sell are recorded at the lower of the aggregate cost or fair value. As of December 31, 2021 and 2020, the Bank had $ 2,844,707 and $ 2,944,962 , respectively, in loans classified as “Mortgage loans held for sale.” Premises and Equipment: Premises and equipment are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related asset. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is reflected in income for the period. The cost of maintenance and repairs which do not improve or extend the useful life of the respective asset is charged to income as incurred, whereas significant renewals and improvements are capitalized. The range of estimated useful lives for premises and equipment is: Building and improvements 20 - 40 years Furniture, automobiles and equipment 5 - 10 years Advertising Costs: Advertising costs are expensed as incurred. Other Real Estate Owned: Other real estate owned represents properties acquired through or by deed in lieu of loan foreclosure and is initially recorded at fair value less estimated costs to sell. Any write-down to fair value at the time of transfer to other real estate owned is charged to the allowance for loan losses. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent adjustments to the value are expensed. Bank owned life insurance: The Bank has purchased life insurance policies on certain key executives and members of management. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other changes or other amounts due that are probable of settlement. Income Taxes: The Company uses the liability method of accounting for income taxes which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Additionally, this method requires the recognition of future tax benefits, such as net operating loss carryforwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. In the event the future tax consequences of differences between the financial reporting bases and the tax bases of the Company’s assets and liabilities results in deferred tax assets, an evaluation of the probability of being able to realize the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the deferred tax asset when it is more likely than not that some portion or all of the deferred tax asset will not be realized. In assessing the realization of the deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. The Company currently evaluates income tax positions judged to be uncertain. A loss contingency reserve is accrued if it is probable that the tax position will be challenged, it is probable that the future resolution of the challenge will confirm that a loss has been incurred, and the amount of such loss can be reasonably estimated. The Company and the Bank file consolidated income tax returns, with income tax expense or benefit computed and allocated on a separate return basis. Post-Retirement Defined Benefit Obligation: The Bank accounts for its post-retirement defined benefit obligations under Accounting Standards Codification (“Codification” or “ASC”) Topic 715, Retirement Benefits (“ASC 715”). The under or over funded status of the Bank’s post-retirement defined benefit obligations are recognized as a liability or asset in the balance sheet. To the extent these obligations are funded, changes in funded status are reflected in other comprehensive income. Net actuarial gains and losses and adjustments to prior service costs that are not recorded as components of the net periodic benefit cost are charged to other comprehensive income. Employee Stock Ownership Plan: The Company sponsors an employee stock ownership plan ("ESOP") that covers all employees who meet certain service requirements. The Company will make annual contributions to the ESOP in amounts as defined by the plan document. These contributions are used to pay debt service and purchase additional shares. Certain ESOP shares are pledged as collateral for debt. As the debt is repaid, shares are released from collateral and allocated to active employees, based on the proportion of debt service paid in the year. In connection with the Company's initial public stock offering, the ESOP borrowed $ 3.9 million payable to the Company for the purpose of purchasing shares of the Company's common stock. A total of 391,868 shares were purchased with the loan proceeds. Because the source of the loan payments are contributions received by the ESOP from the Company, the related note receivable is shown as a reduction of shareholders' equity. Revenue from Contracts with Customers: The Company has adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Accounting Standards Codification (“ASC”) Topic 606”) (“ASU 2014-09”). The Company concluded ASU 2014-09 did not change the timing or presentation of revenue recognition for its current revenue streams. The majority of the Company’s revenues are interest earned on loans, investment securities, and other financial instruments which are unaffected as they are outside the scope of ASU 2014-09. ASC Topic 606 focuses on revenues from contracts earned over time. Fee income, which is within the scope of Topic 606, is generally earned over a short period of time, such as monthly, or is earned concurrently with a specific transaction. The Company records a gain or loss from the sale of other real estate owned (“OREO”) when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. There are no ASC Topic 606 implications unless the Company finances the sale of the OREO property. ASC Topic 606 could change the timing of revenue recognition in the case of seller financing. Comprehensive Income (Loss): The Company has elected to present comprehensive income in a separate statement of comprehensive income. Accumulated other comprehensive income includes the net of tax effect of unrealized gains (losses) on securities available-for-sale and the unfunded post-retirement benefit obligation of the Company’s defined benefit plan. Earnings per Share: Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed in a manner similar to that of basic earnings per share except that the weighted-average number of common shares outstanding is increased to include the number of incremental commons shares (computed using the treasury method) that would have been outstanding if all potentially dilutive common stock equivalents were issued during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. For the year December 31, 2021, earnings per share is calculated for the period that the Company's shares of common stock were outstanding (July 20, 2021 through December 31, 2021). The net earnings for this period was approximately $ 1,159,598 and the weighted average shares outstanding were 4,371,646 . Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation. Emerging Growth Company Status: The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). For as long as the Company is an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies. An emerging growth company may elect to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies, but must make such election when the company is first required to file a registration statement. The Company elected to use the extended transition period described above and intends to maintain its emerging growth company status as allowed under the JOBS Act. Recent Accounting Pronouncements: In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments . This update will require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now include forward-looking information in the determination of their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, this update amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In November 2019, the FASB issued ASU 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) . This update clarified the effective date of ASC 2016-13 for nonpublic business entities to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early application of ASU 2016-13 will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the standard will have on its consolidated condensed financial statements. In August 2018, the FASB issued ASU 2018-13 – Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU amends the disclosure requirements for recurring and nonrecurring fair value measurements by removing, modifying, and adding certain disclosures. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this ASU did not have a significant impact on the Company's consolidated condensed financial statements. In August 2018, the FASB issued ASU 2018-14 – Compensation – Retirement Benefits – Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU removes disclosures that no longer are considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. This ASU is effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. Management does not expect the adoption of this ASU to have a significant impact on the Company's consolidated condensed financial statements. In December 2019, the FASB issued ASU 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted, including adoption in any interim period for (1) public business entities for periods for which financial statements have not yet been issued and (2) all other entities for periods for which financial statements have not yet been made available for issuance. An entity that elects to early adopt the amendments in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. Management does not expect the adoption of this ASU to have a significant impact on the Company's consolidated condensed financial statements. In May 2021, the FASB issued ASU 2021-04- Earning per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) . This ASU provides clarity and reduction in diversity in an issuer's accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. The amendments in this ASU affect all entities that issue freestanding written call options that are classified in equity. Specifically, the amendments affect those entities when a freestanding equity-classified written call option is modified or exchanged and remains equity classified after the modification or exchange. The amendments that relate to the recognition and measurement of EPS for certain modifications or exchanges of freestanding equity-classified written call options affect entities that present EPS in accordance with the guidance in Topic 260, Earnings per Share. The amendments do not apply to modifications or exchanges of financial instruments that are within the scope of another Topic. The amendments do not affect a holder's accounting for freestanding call options. The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the amendments prospectively to modifications or exchanges occurring on or after the effective date of the amendments. Management does not expect the adoption of this ASU to have a significant impact on the Company's consolidated condensed financial statements.

At December 31, 2021, unrealized losses in the investment portfolio related to debt securities. The unrealized losses on the debt securities arose due to changing interest rates and market conditions and are considered to be temporary because of acceptable investment grades or the repayment sources of principal and interest are backed by government entities. At December 31, 2021, all US treasuries, four of fourteen mortgage backed securities, seven of thirteen collateralized mortgage obligations, eight of nine municipal bonds and all corporate obligations contained unrealized losses. The Bank does not intend to sell the investments and it is not likely that the Bank will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity. The amortized cost and estimated fair value of investment securities available-for-sale at December 31, 2021, by contractual maturity, are shown below.

Although the Bank has a diversified loan portfolio, a substantial portion of the loan portfolio is collateralized by improved and unimproved real estate and is dependent on the real estate market. The Bank has divided the loan portfolio into seven portfolio segments, each with different risk characteristics and methodologies for assessing risk. The portfolio segments identified by the Bank are real estate - residential, real estate - home equity, real estate - multi-family, real estate - commercial, real estate - construction and land development, consumer loans and commercial and industrial loans. Real Estate - Residential: The Bank originates residential real estate loans for the purchase or refinancing of a mortgage. These loans are primarily collateralized by owner-occupied properties and rental properties located primarily in the Bank’s market areas. Real Estate - Home Equity: The Bank originates home equity real estate loans to provide home equity lines of credit and closed-end home equity loans. These loans are primarily collateralized by owner-occupied properties located primarily in the Bank’s market areas. Real Estate - Multi-family: Multi-family loans consist of loans to finance real estate purchases, refinancings, expansions and improvements to multi-family properties. These loans may be secured by, but are not limited to, first liens on apartments, mobile home parks or other multi-family properties primarily located within the Bank’s market areas. The Bank’s underwriting analysis includes credit verification, independent appraisals, a review of the borrower’s and borrower’s related entities’ financial condition, and a detailed analysis of the borrower’s underlying cash flows. Multi-family loans are larger than residential or home equity loans and involve greater credit risk. The repayment of these loans largely depends on the results of operations and management of these properties. Adverse economic conditions also affect the repayment ability to a greater extent than residential or home equity real estate loans. Real Estate - Commercial: Commercial real estate loans consist of loans to finance real estate purchases, refinancings, expansions and improvements to commercial properties. These loans may be secured by first liens on office buildings, farms, retail and mixed-use properties, churches, warehouses and restaurants primarily located within the Bank’s market areas. The Bank’s underwriting analysis includes credit verification, independent appraisals, a review of the borrower’s and borrower’s related entities’ financial condition, and a detailed analysis of the borrower’s underlying cash flows. Commercial real estate loans are larger than residential loans and involve greater credit risk. The repayment of these loans largely depends on the results of operations and management of these properties. Adverse economic conditions also affect the repayment ability to a greater extent than residential real estate loans. Real Estate - Construction and land development: These loans are made to borrowers to build commercial structures, a primary or secondary residence and, in some cases, to real estate investors to acquire and develop land. These loans are more difficult to evaluate since they are significantly more vulnerable to changes in economic conditions. In addition, these loans possess a higher degree of credit risk since they are made based on estimates of the future worth of a project and the estimated costs required for completion. The Bank limits its overall investment in this portfolio segment due both to management’s assessment of risk and certain percentage guidance set by the regulatory agencies. Consumer: Consumer loans mainly consist of personal loans, revolving credit plans and other loans. The Bank’s consumer loans may be uncollateralized and rely on the borrower’s income for repayment. Commercial and industrial: Commercial and industrial loans consist generally of business loans and lines of credit to companies in the Bank’s market area. Commercial and industrial loans are generally used for working capital purposes or for acquiring equipment, inventory or furniture. Such loans are usually collateralized by the financed assets, although a portion may be made on an unsecured basis and contain the guarantee of the business principals. The Bank’s underwriting analysis consists of a review of the financial statements of the borrower, the lending history of the borrower, the debt service capabilities of the borrower, the projected cash flows of the business, the value of the collateral, if any, and whether the loan is guaranteed by the principals of the borrower. Commercial and industrial loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business, which makes them of higher risk than residential loans and the collateral securing loans may be difficult to appraise and may fluctuate in value based on the success of the business. Commercial and industrial loans also include loans originated under the Paycheck Protection Program (“PPP”), as prescribed in the CARES Act. These loans have an interest rate of 1.0 % and a two-year or five-year loan term to maturity. The Small Business Administration (“SBA”) guarantees 100 % of the PPP loans made to eligible borrowers, and loan proceeds may be partially or fully forgiven by the SBA if the funds are used for eligible expenses during the relevant forgiveness period and the borrower meets the employee retention criteria. The Bank was paid a processing fee from the SBA on PPP loan originations ranging from 1 % to 5 %, based on the size of the loans. During the years ended December 31, 2021 and 2020, the Bank recorded approximately $ 481,000 and 478,000 , respectively, in PPP-related SBA fees in total and is accreting these fees into interest income over the estimated life of the applicable loans. If a PPP loan is forgiven or paid off before maturity, the remaining unearned fee is recognized into income at that time. As of December 31, 2021 and 2020, the Bank has recognized approximately $ 678,000 and $ 218,000 , respectively, in PPP-related SBA fees through accretion. The majority of the remaining unearned fees are expected to be recognized as the PPP loans are forgiven or paid off. Deferred PPP-related SBA fees totaled $ 62,000 and $ 260,000 at December 31, 2021 and 2020, respectively. Allowance for Loan Losses: The following schedule presents a roll-forward of the allowance for loan losses as of December 31: Year Ended December 31, 2021 2020 Beginning balance $ 4,085,719 $ 3,064,777 Charge-offs: Real estate loans: Residential ( 11,123 ) ( 2,951 ) Home equity — ( 1,377 ) Multi-family — — Commercial — ( 62,896 ) Construction and land development — ( 629 ) Total real estate loans ( 11,123 ) ( 67,853 ) Consumer loans ( 48,022 ) — Commercial and industrial loans ( 78,219 ) ( 149 ) Total charge-offs ( 137,364 ) ( 68,002 ) Recoveries: Real estate loans: Residential 33,794 123,368 Home equity — — Multi-family — — Commercial 19,651 — Construction and land development 24,392 31,573 Total real estate loans 77,837 154,941 Consumer loans 6,595 7,910 Commercial and industrial loans 27,629 146,335 Total recoveries 112,061 309,186 Net (charge offs) recoveries ( 25,303 ) 241,184 Provision for allowance for loan losses 123,183 779,758 Ending balance $ 4,183,599 $ 4,085,719 Allowance for Loan Losses (Continued): The following tables present the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method as of December 31, 2021 and 2020: Loans Allowance for loan losses Individually Collectively Individually Collectively December 31, 2021 -

As of December 31, 2020, there was one loan greater than 90 days past due and still accruing totaling approximately $ 16,000 . Troubled Debt Restructurings: The Bank did not modify any loans in 2021 or 2020 in a manner that would be considered troubled debt restructurings. There were no specific allowances allocated to troubled debt restructurings as of December 31, 2021 or 2020. The Bank did not commit to lend any additional amounts to customers with outstanding loans that are classified as troubled restructurings. Certain troubled debt restructurings are accruing loans in which interest is earned when payments are made. Management continues to evaluate these accruing troubled debt restructurings for impairment on a quarterly basis. During the years ended December 31, 2021 and 2020, no restructured loans defaulted subsequent to modification. COVID-19 Related Loan Modifications: The Bank implemented a customer payment deferral program to assist borrowers that may be experiencing financial hardship due to COVID-19 related challenges, whereby short-term deferrals of payments (generally three to six months) have been provided. As of December 31, 2020, all loans that were granted COVID-19 related payment deferrals had resumed making payments under the terms of the original loan agreements. Consistent with industry regulatory guidance, borrowers that were otherwise current on loan payments that were granted COVID-19 related financial hardship payment deferrals continued to be reported as current loans throughout the agreed upon deferral period and were not classified as troubled debt restructurings. Credit Quality: The Bank categorized 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 Bank analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a continuous basis. The Bank uses the following definitions for its risk ratings: Special Mention. Evidence of financial deterioration exists, or file documentation is inadequate or not available to determine the borrower’s financial status or ability to repay. The loan possesses potential weakness which may, if not reversed or corrected, weaken the credit or inadequately protect the Bank’s position. Substandard. A well-defined weakness or weaknesses exists that jeopardizes the liquidation of the debt. The loan is characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Doubtful. All of the weaknesses of a substandard loan exist, with the added characteristic that the weaknesses jeopardize the collection and/or liquidation of the debt. Loss exposure, while evident, is not clearly determinable. Special workout negotiations and/or litigation should be initiated. Loss. Considered uncollectible in full and of such little value that its continuance as a bankable asset is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this asset even though partial recovery may be achieved in the future. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be Pass rated loans. As of December 31, 2021 and 2020, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: Credit Exposure Based on Risk Ratings: Pass Special Substandard Doubtful Loss Total December 31, 2021 - Real estate loans: Residential $ 95,421,741 $ 1,764,789 $ 1,246,594 $ — $ — $ 98,433,124 Home equity 11,510,661 — — — — 11,510,661 Multi-family 19,937,187 — — — — 19,937,187 Commercial 78,797,687 8,075,262 2,957,662 — — 89,830,611 Construction and land 31,347,154 2,920,406 134,142 — — 34,401,702 Total real estate loans 237,014,430 12,760,457 4,338,398 — — 254,113,285 Consumer loans 1,373,761 — — — — 1,373,761 Commercial and industrial loans 15,900,097 — — 15,900,097 $ 254,288,288 $ 12,760,457 $ 4,338,398 $ — $ — $ 271,387,143 December 31, 2020 - Real estate loans: Residential $ 102,229,498 $ 1,243,538 $ 2,364,288 $ — $ — $ 105,837,324 Home equity 8,891,742 — 675 — — 8,892,417 Multi-family 14,831,774 308,694 — — — 15,140,468 Commercial 67,305,357 4,073,313 1,339,199 — — 72,717,869 Construction and land 25,390,597 2,950,389 1,641,520 — — 29,982,506 Total real estate loans 218,648,968 8,575,934 5,345,682 — — 232,570,584 Consumer loans 5,372,529 — — — — 5,372,529 Commercial and industrial loans 27,643,564 466,020 1,490,398 — — 29,599,982 $ 251,665,061 $ 9,041,954 $ 6,836,080 $ — $ — $ 267,543,095

Commitments And Contingencies Disclosure [Abstract]
Commitments	NOTE 8 - COMMITMENTS Credit Related Financial Instruments: The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. The contractual amounts of those instruments reflect the extent of involvement the Bank has in particular classes of financial instruments. The Bank’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. In most cases, the Bank requires collateral or other security to support financial instruments with credit risk. December 31, 2021 December 31, 2020 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 28,204,000 $ 30,288,000 Stand-by letters of credit $ 931,000 $ 725,000 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank, upon extension of credit is based on management’s credit evaluation. Collateral held varies but may include unimproved and improved real estate, certificates of deposit, or personal property. Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to businesses within the Bank’s trade area. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds real estate and assignments of deposit accounts as collateral supporting those commitments for which collateral is deemed necessary. The extent of collateral held for these commitments at December 31, 2021 and 2020 varies.

Regulatory Matters

Regulatory Capital Requirements [Abstract]
Regulatory Matters	NOTE 10 - REGULATORY MATTERS The Bank is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under certain adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. In July 2013, the Federal bank regulatory agencies issued a final rule that revised their risk-based capital requirements and the method for calculating components of capital and of computing risk-weighted assets to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision and certain provisions of the Dodd-Frank Act. The final rule applies to all depository institutions and, pursuant to the Federal Reserve Board’s policy statements, to top-tier bank and savings and loan holding companies with total consolidated assets of $ 3.0 billion or more. The rule established a new common equity Tier 1 minimum capital requirement, increased the minimum capital ratios and assigned a higher risk weight to certain assets based on the risk associated with these assets. The final rule includes a transition period that implements the new regulations over a five-year period. These changes were phased in beginning in January 2015. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios of total common equity Tier 1, total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2021 and 2020, that the Bank met all capital adequacy requirements to which it is subject. As of December 31, 2021 and 2020, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum common equity Tier 1 risk-based, total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth below. There are no conditions or events since that notification that management believes have changed the institution’s category. The Bank’s actual capital amounts and ratios, and minimum amounts under current regulatory standards, as of December 31, 2021 and 2020, are presented in the following table: Actual For Capital To Be Well Amount Ratio Amount Ratio Amount Ratio (Dollars in Thousands) December 31, 2021: Common Equity Tier 1 Capital to Risk- $ 63,764 25.08 % $ 11,441 4.50 % $ 16,526 6.50 % Total Capital to Risk- Weighted Assets $ 66,954 26.33 % $ 20,340 8.00 % $ 25,425 10.00 % Tier 1 Capital to Risk- Weighted Assets $ 63,764 25.08 % $ 15,255 6.00 % $ 20,340 8.00 % Tier I Capital to Average Assets $ 63,764 16.64 % $ 15,327 4.00 % $ 19,159 5.00 % December 31, 2020: Common Equity Tier 1 Capital to Risk- $ 40,090 16.46 % $ 10,963 4.50 % $ 15,835 6.50 % Total Capital to Risk- Weighted Assets $ 43,148 17.71 % $ 19,489 8.00 % $ 24,361 10.00 % Tier 1 Capital to Risk- Weighted Assets $ 40,090 16.46 % $ 14,617 6.00 % $ 19,489 8.00 % Tier I Capital to Average Assets $ 40,090 11.73 % $ 13,673 4.00 % $ 17,091 5.00 %

Employee Benefits And Share Based Compensation [Abstract]
Employee Benefit Plans	NOTE 11 - EMPLOYEE BENEFIT PLANS 401(k): The Bank sponsors a 401(k) plan. The 401(k) plan covers substantially all employees and provides for an employer matching contribution based on a percentage of salary contributed to the plan. The Bank contributed approximately $ 210,000 and $ 201,000 to the 401(k) plan during 2021 and 2020, respectively. Supplemental Executive Retirement Plans: During 2019, the Bank entered into supplemental executive retirement agreements (each, a “SERP”) with certain of its officers whereby a specified monthly benefit is payable upon a normal retirement for a period of 10 years . Each SERP is a nonqualified deferred compensation arrangement that conditions payment of the full normal retirement benefit upon an officer’s attaining normal retirement age while in the service of the Bank. Otherwise, the retirement benefit is earned over time and, with the exception of the SERPs for a former and a current executive officer, is subject to a ten-year vesting schedule. Moreover, the amount and timing of payment of the retirement benefit may vary depending upon the circumstances of an officer’s earlier termination of employment, including death, disability, or in connection with a change in control. The retirement benefit is forfeited in the event of a termination of employment for cause or if grounds exist for such a termination. The expense associated with the SERPs is offset by earnings on life insurance policies owned by the Bank. The cash surrender value on these insurance policies was approximately $ 11,167,000 and $ 10,883,000 as of December 31, 2021 and 2020, respectively. Additionally, at December 31, 2021 and 2020, the Bank has recorded a liability for the present value of the future retirement benefits of approximately $ 641,000 and $ 491,000 , respectively, to be paid under the SERPs. Expense for the SERPs was approximately $ 150,000 and $ 288,000 for the years ended December 31, 2021 and 2020, respectively. In determining the SERPs obligation for 2021 and 2020, the discount rate used was 2.17 % and 2.18 %, respectively. Director Deferred Fee Practice: The Bank has maintained a discretionary practice of paying a retirement benefit to eligible non-employee directors who attain at least age 70 in the service of the Bank with at least 15 years of service to their credit. Under this practice, each eligible retired director received a monthly benefit in the amount of $ 825 . In anticipation of the Reorganization (see Note 13), the Bank decided to formalize and revise this practice in 2020. The Bank has relinquished its discretion over the practice with respect to eligible retired directors and current non-employee directors who satisfied the eligibility criteria for the benefit as of December 31, 2019. The normal retirement benefit for this group will be a monthly benefit in the amount of $ 825 a month for the remaining life of the director. With respect to all other non-employee directors serving as of December 31, 2019, the amount of the normal monthly benefit will remain unchanged, but will be paid over a period of 10 years following retirement or, if less, the director’s remaining lifetime. The eligibility criteria for this group has been changed to the attainment of at least age 65 with at least 10 years of service. No future non-employee director will be eligible for a benefit under this formalized plan. The Bank has recorded and will continue to record a liability for these payments as post-retirement defined benefit obligations. The Bank recognized current year expense of $ 47,000 and $ 46,000 during the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021 and 2020, the Bank had a projected defined benefit obligation of approximately $ 498,000 and $ 610,000 , respectively, assuming the continuation of its then existing practice. The discount rate used in determining the accumulated post-retirement defined benefit obligation was 2.17 % in 2021 and 2.18 % in 2020. Tax-Qualified Frozen Defined Benefit Pension Plan: The Bank also sponsors a tax-qualified defined benefit retirement plan. Effective March 31, 2019, eligibility for the plan was frozen so that no employee who was not then a participant in the plan could later become a participant and to freeze benefit accruals for all existing participants. For existing participants, the plan provides for retirement payments based on a formula using a participant’s years of creditable service and highest three years of annual compensation. Retirees age 66 and older are also eligible for an annual supplemental payment equal to one percent of their monthly benefit multiplied by the number of their retirement years beyond age 65. Participants who entered the plan prior to July 1, 1983 are also eligible for a one-time lump sum payment upon retirement after reaching age 55 equal to three times their monthly retirement benefit. A participant is also required to vest in any benefit earned under the plan formula by completing a minimum number of years of vesting service. The plan also provides for disability benefits and surviving spouse benefits in circumstances where the normal retirement benefit would not otherwise be payable. Tax-Qualified Frozen Defined Benefit Pension Plan (Continued): The following is a summary of the components of the net periodic post-retirement benefit cost during 2021 and 2020: 2021 2020 Interest cost $ 300,973 $ 366,543 Expected return on assets ( 710,539 ) ( 643,058 ) Amortization of unrecognized loss 219,288 142,053 Periodic post-retirement cost (benefit) $ ( 190,278 ) $ ( 134,462 ) The discount rate used in determining the accumulated post-retirement benefit obligation was 2.33 % a nd 3.09 % in 2021 and 2020, respectively. The expected long-term rate of return on assets was 8.00 % during both 2020 and 2021. The assumed rates of salary increase used in measuring the accumulated post-retirement benefit obligation ranged from 5.35 % to 10.10 % during 2021 and 2020. The Bank expects to make contributions to the plan in 2022 totaling $ 0 .

The plan’s investment policy includes various guidelines and procedures designed to ensure assets are invested in a manner necessary to meet expected future benefits earned by participants. The investment guidelines consider a broad range of economic conditions. Central to the policy are target allocation ranges by major asset categories. The objectives of the target allocations are to maintain investment portfolios that diversify risk through prudent asset allocation parameters, achieve asset returns that meet or exceed the plan’s actuarial assumptions and achieve asset returns that are competitive with like institutions employing similar investment strategies.

The ESOP is a tax-qualified retirement plan for the benefit of Company employees. Contributions are allocated to eligible participants on the basis of compensation, subject to federal limits. The Company uses the principal and interest method to determine the release of shares amounts. The number of shares committed to be released per year through 2040 is approximately 19,600 . The ESOP funded its purchase of 391,868 shares through a loan from the Company equal to 100% of the aggregate purchase price of the common stock. The ESOP trustee will repay the loan principally through the Bank's contributions to the ESOP over the remaining loan term of 19 years. At December 31, 2021, the remaining principal balance on the ESOP debt was $ 3.7 million. Under applicable accounting requirements, the Company records compensation expense for the ESOP equal to the fair market value of shares when they are committed to be released from the suspense account to participants' accounts under the plan. Total compensation expense recognized in connection with the ESOP for the year ended December 31, 2021 was approximately $ 335,000 . 2021 Shares held by the ESOP include the following: Allocated — Committed to be allocated 19,593 Unallocated 372,275 Total 391,868

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 12 - FAIR VALUE MEASUREMENT The Bank utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. From time to time, the Bank may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans and other real estate owned. These nonrecurring fair value adjustments typically involve application of the lower of cost or market accounting or write-downs of individual assets. Additionally, the Bank is required to disclose, but not record, the fair value of other financial instruments. Fair Value Hierarchy The Bank groups assets at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 - Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Assets Recorded at Fair Value on a Recurring Basis. The table below presents the recorded amount of assets measured at fair value on a recurring basis as of December 31, 2021 and 2020, all of which consisted of investment securities available-for-sale: Level 1 Level 2 Level 3 Total December 31, 2021: US treasuries $ — $ 5,104,004 $ — $ 5,104,004 Mortgage-backed securities — 10,369,291 — 10,369,291 Collateralized mortgage obligations — 18,729,594 — 18,729,594 Municipal bonds — 8,597,201 8,597,201 Corporate obligations — 2,831,546 — 2,831,546 Investment securities available-for-sale $ — $ 45,631,636 $ — $ 45,631,636 December 31, 2020: Mortgage-backed securities $ — $ 6,280,605 $ — $ 6,280,605 Collateralized mortgage obligations — 9,135,065 — 9,135,065 Corporate obligations — 501,196 — 501,196 Investment securities available-for-sale $ — $ 15,916,866 $ — $ 15,916,866 Assets Recorded at Fair Value on a Nonrecurring Basis. The Bank may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These include assets that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period. Assets measured at fair value on a nonrecurring basis are included in the table below as of December 31, 2021 and 2020: Level 1 Level 2 Level 3 Total December 31, 2021: Other real estate owned $ — $ — $ 1,115,100 $ 1,115,100 Impaired loans — — — — $ — $ — $ 1,115,100 $ 1,115,100 December 31, 2020: Other real estate owned $ — $ — $ 81,000 $ 81,000 Impaired loans — — — — $ — $ — $ 81,000 $ 81,000 The following methods and assumptions were used to estimate the fair value of each class of assets and liabilities either recorded or disclosed at fair value. Cash and Cash Equivalents. The carrying value of cash and cash equivalents is a reasonable estimate of fair value. Certificates of deposit with other banks. The carrying value of certificates of deposit with other banks is a reasonable estimate of fair value. Investment Securities Available-for-Sale. Investment securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange and U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter market funds. Level 2 securities include mortgage-backed securities and collateralized mortgage obligations issued by government sponsored enterprises and state, county and municipal bonds. Securities classified as Level 3 include asset-backed securities in less liquid markets. Other Investments. Other investments consist of FHLB stock whose carrying value approximates its fair value. Mortgage Loans Held for Sale. The estimated fair value of mortgage loans held for sale, classified within Level 2, is approximated by the carrying value, given the short-term nature of the loans and similarly to what secondary markets are currently offering for portfolios of loans with similar characteristics. Loans. The Bank does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and a specific allocation is established within the allowance for loan losses. Loans for which it is probable that payment of interest and/or principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures impairment using one of three methods, including collateral value, market value of similar debt, and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. Impaired loans in which an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price, the Bank records the impaired loan as nonrecurring Level 2. When an appraised value is utilized or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Bank records the impaired loan as nonrecurring Level 3. Other Real Estate Owned. Other real estate owned properties are adjusted to fair value less estimated selling costs upon transfer of the loans to other real estate owned. Subsequently, other real estate owned assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value is based on an observable market price, the Bank records the other real estate owned as nonrecurring Level 2. When the fair value is based on an appraised value, or when an appraised value is not available, the Bank records the other real estate owned asset as nonrecurring Level 3. Bank Owned Life Insurance. The carrying value of Bank Owned Life Insurance approximates fair value. Commitments to Extend Credit. Commitments to extend credit are short-term and, therefore, the carrying value and the fair value are considered immaterial for disclosure. Deposits. The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of savings accounts approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered to a schedule of aggregated expected maturities of time deposits. Federal Home Loan Bank Advances. Federal Home Loan Bank advances are carried at cost and the fair value is obtained from the Federal Home Loan Bank of Atlanta. The carrying amounts and estimated fair values of the Bank’s financial instruments as of December 31, 2021 and 2020 are as follows: Fair Value Measurements at December 31, 2021 Carrying Total Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 41,890,831 $ 41,890,831 $ 41,890,831 $ — $ — Certificates of deposit with other banks 3,451,000 3,451,000 3,451,000 — — Investment securities available-for-sale 45,631,636 45,631,636 — 45,631,636 — Other investments 190,700 190,700 — 190,700 — Mortgage loans held for sale 2,844,707 2,844,707 — 2,844,707 — Loans, net 266,304,448 274,168,000 — — 274,168,000 Bank owned life insurance 11,166,573 11,166,573 11,166,573 — — Financial liabilities: Deposits 289,316,708 289,267,454 216,786,454 — 72,481,000 Fair Value Measurements at December 31, 2020 Carrying Total Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 41,876,399 $ 41,876,399 $ 41,876,399 $ — $ — Certificates of deposit with other banks 5,652,000 5,652,000 5,652,000 — — Investment securities available-for-sale 15,916,866 15,916,866 — 15,916,866 — Other investments 714,000 714,000 — 714,000 — Mortgage loans held for sale 2,944,962 2,944,962 — 2,944,962 — Loans, net 262,355,967 277,366,000 — — 277,366,000 Bank owned life insurance 10,883,428 10,883,428 10,883,428 — — Financial liabilities: Deposits 294,099,827 313,033,000 207,523,546 — 105,509,454 FHLB advances 9,515,477 9,631,000 — — 9,631,000 Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Bank’s financial instruments, fair value estimates are based on judgments. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect these estimates.

Change In Corporate Form [Abstract]
Change In Corporate Form	NOTE 13 – CHANGE IN CORPORATE FORM The Bank converted to the stock form of ownership, followed by the issuance of all of the Bank’s outstanding stock to the Company (the "Conversion"). The Bank became the wholly owned subsidiary of the Company, and the Company issued and sold shares of its capital stock pursuant to an independent valuation appraisal of the Bank and the Company. The stock was priced at $ 10.00 per share. In addition, the Bank’s board of directors adopted an employee stock ownership plan ("ESOP") which subscribed for 8 % of the common stock sold in the offering. The Conversion was completed on July 20, 2021 and resulted in the issuance of 4,898,350 common shares by the Company, of which 391,868 were issued to the ESOP. The cost of the Conversion and issuing the capital stock totaled $ 1.5 million and was deducted from the proceeds of the offering. In accordance with OCC regulations, at the time of the Conversion, the Bank substantially restricted retained earnings by establishing a $ 42.0 million liquidation account. The liquidation account will be maintained for the benefit of eligible account holders who continue to maintain their accounts at the Bank after the Conversion. The liquidation account will be reduced annually to the extent that eligible holders have reduced their qualifying deposits. Subsequent increases will not restore an eligible account holder’s interest in the liquidation account. In the event of a complete liquidation by the Bank, and only in such event, each eligible account holder will be entitled to receive a distribution from the liquidation account in an amount proportionate to the adjusted qualifying account balances then held. The Bank may not pay dividends if those dividends would reduce equity capital below the required liquidation account amount. The Conversion was accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result. Deferred conversion costs totaled approximately $ 116,000 at December 31, 2020. Stock offering expenses totaled $ 1,523,443 , which were deducted from the proceeds from the sale of common stock.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations: TC Bancshares, Inc. ("Company") is a savings and loan holding company incorporated under the laws of the State of Georgia in 2021, to serve as the holding company for TC Federal Bank ("Bank"). The Company owns 100 % of the outstanding stock of the Bank. See Note 13 for a detailed discussion of the Company. The Bank was organized in 1934 and chartered in 1937 by the Federal Home Loan Bank Board as a mutual savings and loan association owned 100% by its depositors. The Bank operates one branch in Thomasville, Georgia, and one in Tallahassee, Florida as well as loan production offices in Tallahassee, Florida and Savannah, Georgia, that provide a variety of services to individuals and corporate customers in their markets. The Bank’s primary deposit products are interest-bearing checking accounts, savings accounts, and certificates of deposit. Its primary lending products consist of single-family residential mortgage loans and commercial and multi-family real estate loans. The Bank is regulated by the Office of the Comptroller of the Currency (“OCC”) and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). The Bank undergoes periodic examinations by the OCC. The Company is subject to the supervision, examination, and reporting requirements of the Bank Holding Company Act and the regulations of the Board of Governors of the Federal Reserve System (the "Federal Reserve").
Basis of Presentation	Basis of Presentation: The accounting and financial reporting policies of the Company and the Bank conform, in all material respects to accounting principles generally accepted in the United States of America (“GAAP”) and with general practices within the banking industry. The consolidated financial statements have been prepared in accordance with GAAP and with the instructions to Form 10-K adopted by the Securities and Exchange Commission (the “SEC”). In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ significantly from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of the post-retirement obligation, and valuation allowance associated with the realization of deferred tax assets, which are based on future taxable income. In 2020, Coronavirus Disease 2019 (COVID-19) spread into a worldwide pandemic. The pandemic may impact various parts of the Company’s future operations and financial results, including additional allowance for loan loss provisions. Management believes the Company is taking appropriate actions to mitigate the negative impact. However, the full impact of COVID-19 on the allowance for loan losses as of December 31, 2021 cannot be reasonably estimated, as these events are still developing.
Cash and Cash Equivalents	Cash and Cash Equivalents: For purposes of reporting cash flows, cash and cash equivalents include cash and balances due from banks and federal funds sold, all of which mature within 90 days. Reserve requirements held in cash on hand or in deposit with the Federal Reserve Bank of Atlanta by the Company were $ 0 at December 31, 2021 and 2020.
Investment Securities	Investment Securities: The Company classifies its securities in one of three categories: trading, available-for-sale, or held-to-maturity. Trading securities are bought and held principally for the purpose of selling them in the near term. Held-to-maturity securities are those securities for which the Company has the ability and intent to hold the security until maturity. All other securities not included in trading or held-to-maturity are classified as available-for-sale. As of December 31, 2021 and 2020, all securities were classified as available-for-sale. Trading and available-for-sale securities are recorded at fair value. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization of premiums and accretion of discounts. Unrealized holding gains and losses, net of the related tax effect, on securities available-for-sale are excluded from income and are reported as a separate component of accumulated other comprehensive income in shareholders’ equity until realized. Transfers of securities between categories are recorded at fair value at the date of transfer. Management evaluates investment securities for other-than-temporary impairment on an annual basis. A decline in the market value of any investment below cost that is deemed other-than-temporary is charged to income for the decline in value deemed to be credit related and a new cost basis in the security is established. The decline in value attributed to non-credit related factors is recognized in other comprehensive income. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to the yield. Realized gains and losses for securities classified as available-for-sale are included in income and are derived using the specific identification method for determining the cost of securities sold.
Other Investments	Other Investments: Other investments are carried at cost and consist of Federal Home Loan Bank of Atlanta (“FHLB”) stock. The Bank is required to hold the FHLB stock as a member of the FHLB, and transfer of the stock is substantially restricted. The stock is pledged as collateral for outstanding FHLB advances.
Loans Loan Fees and Interest Income on Loans	Loans, Loan Fees and Interest Income on Loans: Loans are stated at the principal amount outstanding, net of the allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions and collection efforts that the borrower’s financial condition is such that collection of interest is doubtful. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is charged to interest income on loans. Generally, payments on nonaccrual loans are applied to principal. Loan fees, net of certain origination costs, are deferred and amortized over the lives of the respective loans. A loan is impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or at the loan’s observable market price, or at the fair value of the collateral of the loan if the loan is collateral dependent. Estimated impairment losses for collateral dependent loans are set up as specific reserves. Interest income on impaired loans is recognized using the cash-basis method of accounting during the time the loans are impaired.
Allowance for Loan Losses	Allowance for Loan Losses: The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The allowance represents an amount which, in management’s judgment based on, among other things, historical losses and on the current economic environment, will be adequate to absorb probable losses on existing loans that may become uncollectible. Loans deemed uncollectible are charged-off and deducted from the allowance and recoveries on loans previously charged-off are added back to the allowance. Management’s judgment in determining the adequacy of the allowance is based on evaluations of the collectability of loans. These evaluations take into consideration such factors as changes in the nature and volume of the loan portfolio, current economic conditions that may affect the borrower’s ability to pay, overall portfolio quality, and review of specific problem loans. Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. As a result of such review, the Bank may have to recognize additions to its allowance for loan losses.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale: The Bank sells mortgage loans for an amount equal to the principal amount of loans with yields to investors based upon current market rates. Realized gains and losses related to loan sales are included in gains on sale of loans and are determined using the specific identification method. For financial reporting purposes, the Bank classifies a portion of its loans as “Mortgage loans held for sale”. Included in this category are loans which the Bank has the current intent to sell and loans which are available to be sold in the event the Bank determines that loans should be sold to support the Bank’s investment and liquidity objectives. Loans included in this category for which the Bank has the current intention to sell are recorded at the lower of the aggregate cost or fair value. As of December 31, 2021 and 2020, the Bank had $ 2,844,707 and $ 2,944,962 , respectively, in loans classified as “Mortgage loans held for sale.”
Premises and Equipment	Premises and Equipment: Premises and equipment are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related asset. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is reflected in income for the period. The cost of maintenance and repairs which do not improve or extend the useful life of the respective asset is charged to income as incurred, whereas significant renewals and improvements are capitalized. The range of estimated useful lives for premises and equipment is: Building and improvements 20 - 40 years Furniture, automobiles and equipment 5 - 10 years
Advertising Costs	Advertising Costs: Advertising costs are expensed as incurred.
Other Real Estate Owned	Other Real Estate Owned: Other real estate owned represents properties acquired through or by deed in lieu of loan foreclosure and is initially recorded at fair value less estimated costs to sell. Any write-down to fair value at the time of transfer to other real estate owned is charged to the allowance for loan losses. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent adjustments to the value are expensed.
Bank Owned Life Insurance	Bank owned life insurance: The Bank has purchased life insurance policies on certain key executives and members of management. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other changes or other amounts due that are probable of settlement.
Income Taxes	Income Taxes: The Company uses the liability method of accounting for income taxes which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Additionally, this method requires the recognition of future tax benefits, such as net operating loss carryforwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. In the event the future tax consequences of differences between the financial reporting bases and the tax bases of the Company’s assets and liabilities results in deferred tax assets, an evaluation of the probability of being able to realize the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the deferred tax asset when it is more likely than not that some portion or all of the deferred tax asset will not be realized. In assessing the realization of the deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. The Company currently evaluates income tax positions judged to be uncertain. A loss contingency reserve is accrued if it is probable that the tax position will be challenged, it is probable that the future resolution of the challenge will confirm that a loss has been incurred, and the amount of such loss can be reasonably estimated. The Company and the Bank file consolidated income tax returns, with income tax expense or benefit computed and allocated on a separate return basis.
Post Retirement Defined Benefit Obligation	Post-Retirement Defined Benefit Obligation: The Bank accounts for its post-retirement defined benefit obligations under Accounting Standards Codification (“Codification” or “ASC”) Topic 715, Retirement Benefits (“ASC 715”). The under or over funded status of the Bank’s post-retirement defined benefit obligations are recognized as a liability or asset in the balance sheet. To the extent these obligations are funded, changes in funded status are reflected in other comprehensive income. Net actuarial gains and losses and adjustments to prior service costs that are not recorded as components of the net periodic benefit cost are charged to other comprehensive income.
Employee Stock Ownership Plan	Employee Stock Ownership Plan: The Company sponsors an employee stock ownership plan ("ESOP") that covers all employees who meet certain service requirements. The Company will make annual contributions to the ESOP in amounts as defined by the plan document. These contributions are used to pay debt service and purchase additional shares. Certain ESOP shares are pledged as collateral for debt. As the debt is repaid, shares are released from collateral and allocated to active employees, based on the proportion of debt service paid in the year. In connection with the Company's initial public stock offering, the ESOP borrowed $ 3.9 million payable to the Company for the purpose of purchasing shares of the Company's common stock. A total of 391,868 shares were purchased with the loan proceeds. Because the source of the loan payments are contributions received by the ESOP from the Company, the related note receivable is shown as a reduction of shareholders' equity.
Revenue from Contracts with Customers	Revenue from Contracts with Customers: The Company has adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Accounting Standards Codification (“ASC”) Topic 606”) (“ASU 2014-09”). The Company concluded ASU 2014-09 did not change the timing or presentation of revenue recognition for its current revenue streams. The majority of the Company’s revenues are interest earned on loans, investment securities, and other financial instruments which are unaffected as they are outside the scope of ASU 2014-09. ASC Topic 606 focuses on revenues from contracts earned over time. Fee income, which is within the scope of Topic 606, is generally earned over a short period of time, such as monthly, or is earned concurrently with a specific transaction. The Company records a gain or loss from the sale of other real estate owned (“OREO”) when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. There are no ASC Topic 606 implications unless the Company finances the sale of the OREO property. ASC Topic 606 could change the timing of revenue recognition in the case of seller financing.
Comprehensive Income (Loss)	Comprehensive Income (Loss): The Company has elected to present comprehensive income in a separate statement of comprehensive income. Accumulated other comprehensive income includes the net of tax effect of unrealized gains (losses) on securities available-for-sale and the unfunded post-retirement benefit obligation of the Company’s defined benefit plan.
Earnings Per Share	Earnings per Share: Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed in a manner similar to that of basic earnings per share except that the weighted-average number of common shares outstanding is increased to include the number of incremental commons shares (computed using the treasury method) that would have been outstanding if all potentially dilutive common stock equivalents were issued during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. For the year December 31, 2021, earnings per share is calculated for the period that the Company's shares of common stock were outstanding (July 20, 2021 through December 31, 2021). The net earnings for this period was approximately $ 1,159,598 and the weighted average shares outstanding were 4,371,646 .
Reclassifications	Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation.
Emerging Growth Company Status	Emerging Growth Company Status: The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). For as long as the Company is an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies. An emerging growth company may elect to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies, but must make such election when the company is first required to file a registration statement. The Company elected to use the extended transition period described above and intends to maintain its emerging growth company status as allowed under the JOBS Act.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments . This update will require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now include forward-looking information in the determination of their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, this update amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In November 2019, the FASB issued ASU 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) . This update clarified the effective date of ASC 2016-13 for nonpublic business entities to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early application of ASU 2016-13 will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the standard will have on its consolidated condensed financial statements. In August 2018, the FASB issued ASU 2018-13 – Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU amends the disclosure requirements for recurring and nonrecurring fair value measurements by removing, modifying, and adding certain disclosures. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this ASU did not have a significant impact on the Company's consolidated condensed financial statements. In August 2018, the FASB issued ASU 2018-14 – Compensation – Retirement Benefits – Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU removes disclosures that no longer are considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. This ASU is effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. Management does not expect the adoption of this ASU to have a significant impact on the Company's consolidated condensed financial statements. In December 2019, the FASB issued ASU 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted, including adoption in any interim period for (1) public business entities for periods for which financial statements have not yet been issued and (2) all other entities for periods for which financial statements have not yet been made available for issuance. An entity that elects to early adopt the amendments in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. Management does not expect the adoption of this ASU to have a significant impact on the Company's consolidated condensed financial statements. In May 2021, the FASB issued ASU 2021-04- Earning per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) . This ASU provides clarity and reduction in diversity in an issuer's accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. The amendments in this ASU affect all entities that issue freestanding written call options that are classified in equity. Specifically, the amendments affect those entities when a freestanding equity-classified written call option is modified or exchanged and remains equity classified after the modification or exchange. The amendments that relate to the recognition and measurement of EPS for certain modifications or exchanges of freestanding equity-classified written call options affect entities that present EPS in accordance with the guidance in Topic 260, Earnings per Share. The amendments do not apply to modifications or exchanges of financial instruments that are within the scope of another Topic. The amendments do not affect a holder's accounting for freestanding call options. The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the amendments prospectively to modifications or exchanges occurring on or after the effective date of the amendments. Management does not expect the adoption of this ASU to have a significant impact on the Company's consolidated condensed financial statements.

Description of eligibility of non-employee directors retirement benefit	The Bank has maintained a discretionary practice of paying a retirement benefit to eligible non-employee directors who attain at least age 70 in the service of the Bank with at least 15 years of service to their credit. Under this practice, each eligible retired director received a monthly benefit in the amount of $825. In anticipation of the Reorganization (see Note 13), the Bank decided to formalize and revise this practice in 2020. The Bank has relinquished its discretion over the practice with respect to eligible retired directors and current non-employee directors who satisfied the eligibility criteria for the benefit as of December 31, 2019. The normal retirement benefit for this group will be a monthly benefit in the amount of $825 a month for the remaining life of the director. With respect to all other non-employee directors serving as of December 31, 2019, the amount of the normal monthly benefit will remain unchanged, but will be paid over a period of 10 years following retirement or, if less, the director’s remaining lifetime. The eligibility criteria for this group has been changed to the attainment of at least age 65 with at least 10 years of service. No future non-employee director will be eligible for a benefit under this formalized plan.
Description of tax-qualified defined benefit retirement plan	The Bank has recorded and will continue to record a liability for these payments as post-retirement defined benefit obligations.
