Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation Community First Bancshares, Inc. (the “Company”) is a savings and loan holding company headquartered in Covington, Georgia. The Company has one operating subsidiary, Newton Federal Bank (the “Bank”), conducting banking activities primarily in Newton County, Georgia and surrounding counties. The main emphasis of the Bank is providing mortgage loans in its primary lending area. It offers customary banking services such as consumer and commercial checking accounts, savings accounts, certificates of deposit, mortgage, commercial and consumer loans, money transfers and a variety of other banking services. The accompanying unaudited consolidated financial statements and notes thereto contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly, in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the financial position of the Company as of June 30, 2018 and the results of its operations and its cash flows for the periods presented. The interim consolidated financial information should be read in conjunction with the annual financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2017. The results of operations for the quarter and nine months ended June 30, 2018, are not necessarily indicative of the results to be expected for the full year or for any other period. Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ 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, the valuation of other real estate acquired in connection with foreclosure or in satisfaction of loans and valuation allowances associated with the realization of deferred tax assets, which are based on future taxable income. Summary of Significant Accounting Policies – The accounting and reporting policies of the Company conform to GAAP and general practices within the banking industry. There have been no material changes or developments in the application of principles or in our evaluation of the accounting estimates and the underlying assumptions or methodologies that we believe to be Critical Accounting Policies as disclosed in the Company’s financial statements for the year ended September 30, 2017 included in the Company’s Form 10-K.

Additionally, all troubled debt restructurings are evaluated for impairment. A loan is considered impaired when, based on current events and circumstances, it is probable that all amounts due according to the contractual terms of the loan 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, at the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. Interest payments received on impaired loans are applied as a reduction of the outstanding principal balance.

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. Loans have potential weaknesses that may, if not corrected, weaken or inadequately protect the Bank's credit position at some future date. Weaknesses are generally the result of deviation from prudent lending practices, such as over advances on collateral. Credits in this category should, within a 12 month period, move to Pass if improved or drop to Substandard if poor trends continue. Substandard. Inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans have a well-defined weakness or weaknesses such as primary source of repayment is gone or severely impaired or cash flow is insufficient to reduce debt. There is a distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Doubtful. Loans have weaknesses of those classified Substandard, with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable. The likelihood of a loss on an asset or portion of an asset classified Doubtful is high. Loss. Loans considered uncollectible and of such little value that the continuance as a Bank asset is not warranted. This does not mean that the loan has no recovery or salvage value, but rather the asset should be charged off even though partial recovery may be possible 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 June 30, 2018 and September 30, 2017, and based on the most recent analysis performed, the risk category of loans by class of loans were as follows: (in thousands) June 30, 2018 Pass Special Mention Substandard Doubtful/ Loss Total Commercial (secured by real estate) $ 36,911 — 580 — 37,491 Commercial and industrial 27,289 — 324 — 27,613 Construction, land and acquisition & development 21,439 — 36 — 21,475 Residential mortgage 128,594 66 9,326 — 137,986 Consumer installment 2,687 — 43 — 2,730 Total $ 216,920 66 10,309 — 227,295 September 30, 2017 Pass Special Mention Substandard Doubtful/ Loss Total Commercial (secured by real estate) $ 29,416 — 445 — 29,861 Commercial and industrial 21,015 — 45 — 21,060 Construction, land and acquisition & development 25,165 — — — 25,165 Residential mortgage 132,725 224 5,926 — 138,875 Consumer installment 2,783 — — — 2,783 Total $ 211,104 224 6,416 — 217,744

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Employee Stock Ownership Plan	( 6 ) Employee Stock Ownership Plan The Company sponsors an employee stock ownership plan (“ESOP”) that covers all employees who meet certain service requirements. The Company makes 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 April 2017, the ESOP borrowed $2,954,990 payable to the Company for the purpose of purchasing shares of the Company’s common stock. A total of 295,499 shares were purchased with the loan proceeds as part of the Company’s initial stock offering. Total ESOP expense for the three and nine months ended June 30, 2018 was approximately $33,000 and $104,000, respectively. There was $64,000 ESOP expense for the three and nine months ended June 30, 2017. The balance of the note payable of the ESOP was $2,820,473 at June 30, 2018. Because the source of the loan payments are contributions received by the ESOP from the Company, the related notes receivable is shown as a reduction of stockholders’ equity. As of June 30, 2018, 11,820 shares have been released.

Stockholders Equity Note [Abstract]
Stockholders' Equity	( 7 ) Stockholders’ Equity Prior to January 1, 1996, the Bank was permitted under the Internal Revenue Code (the “Code”) a special bad debt deduction related to additions to tax bad debt reserves established for the purpose of absorbing losses. The provisions of the Code permitted the Bank to deduct from taxable income an allowance for bad debts based on the greater of a percentage of taxable income before such deduction or actual loss experience. Retained earnings at June 30, 2018 includes approximately $3,625,000 for which no deferred Federal income tax liability has been recognized. The amounts represent an allocation of income for bad debt deductions for tax purposes only. Reduction of amounts so allocated for purposes other than tax bad debt losses would create income for tax purposes only, which would be subject to the then current corporate income tax rate. On August 20, 1996, legislation was passed which eliminated the percentage of taxable income bad debt deduction for thrift institutions for tax years beginning after December 31, 1995. This legislation also requires a thrift to generally recapture the excess of its current tax reserves over its 1987 base year reserves whereas the base year reserves are frozen from taxation. No additional financial statement tax expense resulted from this legislation as the Bank had previously provided deferred taxes on this recaptured amount. A write down of our deferred tax assets by approximately $1.0 million was made in the quarter ended December 31, 2017 as a result of the enactment of the Tax Cuts and Jobs Act of 2017, which reduced the maximum federal corporate income tax rate to 21% from 35%. The write-down is subject to adjustment in future periods. On October 31, 2016, the Board of Directors of the Bank adopted a Plan of Reorganization from a Mutual Savings Association to a Mutual Holding Company and Stock Issuance Plan (the “Plan”). The Plan was subject to the approval of the Board of Governors of the Federal Reserve System and the affirmative vote of at least a majority of the total votes eligible to be cast by the voting members of the Bank at a special meeting. Pursuant to the Plan, on April 27, 2017 the Bank converted to a stock savings bank and is now organized in the mutual holding company structure. The Bank issued all of its outstanding stock to the Company, which sold 3,467,595 shares of common stock to the public at $10.00 per share, representing 46% of its outstanding shares of common stock. This amount included shares purchased by the Bank’s employee stock ownership plan (“ESOP”), which purchased 3.92% of the common stock of the new holding company outstanding upon the completion of the reorganization and stock issuance. The Company is organized as a corporation under the laws of the United States. Community First Bancshares, MHC has been organized as a mutual holding company under the laws of the United States and owns 54% of the outstanding common stock of the Company.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Disclosures	(8 ) Fair Value Measurements and Disclosures The Company 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 Company 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 Company is required to disclose, but not record, the fair value of other financial instruments. Fair Value Hierarchy The Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities 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 or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Following is a description of valuation methodologies used for assets and liabilities recorded at fair value. Cash and Cash Equivalents The carrying value of cash and cash equivalents is a reasonable estimate of fair value. Investment Securities Available-for-Sale Available-for-sale securities are recorded at market value. 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 issued by government sponsored enterprises and state, county and municipal bonds. Securities classified as Level 3 include asset-backed securities in less liquid markets. Investment Securities Held-to-Maturity Held-to-maturity securities are recorded at cost, adjusted for the amortization or accretion of premiums and discounts. 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 issued by government sponsored enterprises and state, county and municipal bonds. Securities classified as Level 3 include asset-backed securities in less liquid markets. FHLB Stock The carrying value of FHLB Stock approximates fair value. Loans and Loans Held for Sale The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and a specific reserve is established within the allowance for loan losses. Loans for which it is probable that payment of interest and 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 in accordance with GAAP. The fair value of impaired loans is estimated 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. In accordance with GAAP, impaired loans where 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 Company records the impaired loan as nonrecurring Level 2. When an appraised value is used or an appraisal is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. For disclosure purposes, the fair value of fixed rate loans which are not considered impaired is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. For unimpaired variable rate loans, the carrying amount is a reasonable estimate of fair value for disclosure purposes. The estimated fair value of 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. Other Real Estate Owned Other real estate properties are adjusted to fair value upon transfer of the loans to other real estate. Subsequently, other real estate assets are carried at fair value less estimated selling costs. 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 of the collateral is based on an observable market price, the Bank records the other real estate as nonrecurring Level 2. When an appraised value is used or an appraisal is not available 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 other real estate asset as nonrecurring Level 3. Bank Owned Life Insurance For disclosure purposes, the carrying value of the cash surrender value of life insurance reasonably approximates fair value. Deposits The fair value of passbook accounts, interest bearing checking accounts, non-interest bearing checking accounts and market rate checking accounts is the amount payable on demand at the reporting date, while the fair value of fixed maturity certificates of deposit is estimated by discounting the future cash flows using current rates at which comparable certificates would be issued. Federal Home Loan Bank Advances For disclosure purposes, the fair value of Federal Home Loan Bank fixed rate borrowings are estimated using discounted cash flows, based on the current incremental borrowing rates for similar types of borrowing arrangements. 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. Assets Recorded at Fair Value on a Recurring Basis The Company’s only assets recorded at fair value on a recurring basis are available-for-sale securities that had fair values of approximately $22,198,000 and $14,345,000 at June 30, 2018 and September 30, 2017, respectively. They are classified as Level 2. Assets Recorded at Fair Value on a Nonrecurring Basis The Company 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 June 30, 2018 and September 30, 2017 (in thousands). June 30, 2018 Level 1 Level 2 Level 3 Total Other real estate owned $ — — — — Impaired loans — — 8,097 8,097 Total assets at fair value $ — — 8,097 8,097 September 30, 2017 Level 1 Level 2 Level 3 Total Other real estate owned $ — — 61 61 Impaired loans — — 8,178 8,178 Total assets at fair value $ — — 8,239 8,239 The carrying amounts and estimated fair values (in thousands) of the Company’s financial instruments at June 30, 2018 and September 30, 2017 are as follows: June 30, 2018 September 30, 2017 Carrying Estimated Carrying Estimated Amount Fair Value Amount Fair Value Financial assets: Cash and cash equivalents $ 26,323 26,323 35,943 35,943 Investment securities available-for-sale $ 22,198 22,198 14,345 14,345 held-to-maturity $ 1,000 990 1,000 1,001 FHLB Stock $ 580 580 216 216 Loans held for sale $ — — 117 117 Loans, net $ 223,286 191,305 213,193 198,637 Cash surrender value of life insurance $ 7,135 7,135 — — Financial liabilities: Deposits $ 203,446 203,075 194,613 194,300 FHLB advances $ 7,570 7,703 — — Limitations 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 Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on many 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 the estimates. Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.
