Nature of Business and Basis of Presentation [Abstract]
Nature of Business and Basis of Presentation	NOTE 1 – Nature of Business and Basis of Presentation Business Activity Southern First Bancshares, Inc. (the "Company") is a South Carolina corporation that owns all of the capital stock of Southern First Bank (the "Bank") and all of the stock of Greenville First Statutory Trust I and II (collectively, the "Trusts"). The Trusts are special purpose non-consolidated entities organized for the sole purpose of issuing trust preferred securities. The Bank's primary federal regulator is the Federal Deposit Insurance Corporation (the "FDIC"). The Bank is also regulated and examined by the South Carolina Board of Financial Institutions. The Bank is primarily engaged in the business of accepting demand deposits and savings deposits insured by the FDIC, and providing commercial, consumer and mortgage loans to the general public. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six month periods ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 as filed with the Securities and Exchange Commission on February 28, 2018. The consolidated financial statements include the accounts of the Company and the Bank. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, “Consolidation,” the financial statements related to the Trusts have not been consolidated. Business Segments In determining proper segment definition, the Company considers the materiality of a potential segment and components of the business about which financial information is available and regularly evaluated, relative to a resource allocation and performance assessment. The Company accounts for intersegment revenues and expenses as if the revenue/expense transactions were generated to third parties, that is, at current market prices. Please refer to “Note 9 – Reportable Segments” for further information on the reporting for the Company’s three business segments. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amount of income and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, real estate acquired in the settlement of loans, fair value of financial instruments, evaluating other-than-temporary-impairment of investment securities and valuation of deferred tax assets. Reclassifications Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on shareholders’ equity or net income. Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management performed an evaluation to determine whether there have been any subsequent events since the balance sheet date and determined that no subsequent events occurred requiring accrual or disclosure. Revenue from Contracts with Customers The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Our accounting policies will not change materially since the principles of revenue recognition from the Accounting Standards Update are largely consistent with existing guidance and current practices applied by our business. The following is a discussion of revenues within the scope of the new guidance: ● Service fees on deposit accounts ● ATM and debit card income - The Company earns interchange fees from debit cardholder transactions conducted through the payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Income Taxes On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. Authoritative guidance and interpretation by regulatory bodies is ongoing, and as such, the accounting for the effects of the Tax Act is not final and the full impact of the new regulation is still being evaluated. The accounting is expected to be complete when the 2017 U.S. corporate income tax return is filed later in 2018. Adoption of New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP. The new standard was effective for the Company on January 1, 2018. Adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASU 2014-09. The Company’s revenue recognition pattern for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposit accounts and gains/losses on the sale of other real estate owned, did not change significantly from current practice. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company elected to use the modified retrospective transition method which requires application of ASU 2014-09 to uncompleted contracts at the date of adoption however, periods prior to the date of adoption will not be retrospectively revised as the impact of the ASU on uncompleted contracts at the date of adoption was not material. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 7 – Fair Value Accounting for further information regarding the valuation of these loans. In February 2018, the FASB Issued (ASU 2018-02), Income Statement (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act. The Company has opted to early adopt this pronouncement by retrospective application to each period (or periods) in which the effect of the change in the tax rate under the Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings did not have a material effect on the Company’s financial statements. Newly Issued, But Not Yet Effective Accounting Standards In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of this ASU is permitted for all entities. Adoption of ASU 2016-02 is not expected to have a material impact on the Company’s consolidated financial statements. The Company leases certain properties under operating leases that will result in the recognition of lease assets and lease liabilities on the Company’s balance sheet under the ASU. At June 30, 2018, the Company had contractual future minimum lease commitments of approximately $14.6 million, before considering renewal options that are generally present. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). Among other things, ASU 2016-13 requires 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 use forward-looking information to form 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, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 31, 2019, and interim periods within those years for public business entities that are SEC filers. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018, however, the Company does not currently plan to early adopt the ASU. We are evaluating the impact of the ASU on our consolidated financial statements. In addition to our allowance for loan losses, we will also record an allowance for credit losses on debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio’s composition and credit quality at the adoption date as well as economic conditions and forecasts at that time. In March 2017, the FASB amended the requirement in the Receivables-Nonrefundable Fees and Other Costs Topic of the Accounting Standards Codification related to the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for the premium to the earliest call date. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements. In February 2018, the FASB amended the Financial Instruments Topic of the Accounting Standards Codification. The amendments clarify certain aspects of the guidance issued in ASU 2016-01. The amendments will be effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.

The unrealized losses were primarily attributable to changes in interest rates, rather than deterioration in credit quality. The individual securities are each investment grade securities. The Company considers the length of time and extent to which the fair value of available-for-sale debt securities have been less than cost to conclude that such securities are not other-than-temporarily impaired. The Company also considers other factors such as the financial condition of the issuer, including credit ratings and specific events affecting the operations of the issuer, volatility of the security, underlying assets that collateralize the debt security, and other industry and macroeconomic conditions. As the Company has no intent to sell securities with unrealized losses and it is not more-likely-than-not that the Company will be required to sell these securities before recovery of amortized cost, the Company has concluded that these securities are not impaired on an other-than-temporary basis. Other investments are comprised of the following and are recorded at cost which approximates fair value.

All of the FHLB stock is used to collateralize advances with the FHLB. At June 30, 2018, $4.2 million of securities were pledged as collateral for repurchase agreements from brokers and no securities were pledged to secure client deposits. At December 31, 2017, $7.7 million of securities were pledged as collateral for repurchase agreements from brokers.

Mortgage Loans Held for Sale [Abstract]
Mortgage Loans Held for Sale	NOTE 3 – Mortgage Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are reported as loans held for sale and carried at fair value under the fair value option with changes in fair value recognized in current period earnings. At the date of funding of the mortgage loan held for sale, the funded amount of the loan, the related derivative asset or liability of the associated interest rate lock commitment, less direct loan costs becomes the initial recorded investment in the loan held for sale. Such amount approximates the fair value of the loan. At June 30, 2018, mortgage loans held for sale totaled $8.1 million compared to $11.8 million at December 31, 2017. Mortgage loans held for sale are considered de-recognized, or sold, when the Company surrenders control over the financial assets. Control is considered to have been surrendered when the transferred assets have been isolated from the Company, beyond the reach of the Company and its creditors; the purchaser obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and the Company does not maintain effective control over the transferred assets through an agreement that both entitles and obligates the Company to repurchase or redeem the transferred assets before their maturity or the ability to unilaterally cause the holder to return specific assets. Gains and losses from the sale of mortgage loans are recognized based upon the difference between the sales proceeds and carrying value of the related loans upon sale and are recorded in mortgage banking income in the statement of income. Mortgage banking income also includes the gains and losses associated with the loans held for sale and the gains and losses from derivatives. Mortgage loans sold by the Company to investors and which were believed to have met investor and agency underwriting guidelines at the time of sale may be subject to repurchase or indemnification in the event of specific default by the borrower or subsequent discovery that underwriting standards were not met. The Company may, upon mutual agreement, agree to repurchase the loans or indemnify the investor against future losses on such loans. In such cases, the Company bears any subsequent credit loss on the loans. The Company establishes mortgage repurchase reserves related to various representations and warranties that reflect management’s estimate of losses based on a combination of factors. The Company establishes a reserve at the time loans are sold and quarterly updates the reserve estimate during the estimated loan life.

The Company applies historic grade-specific loss factors to each loan class. In the development of statistically derived loan grade loss factors, the Company observes historical losses over 20 quarters for each loan grade. These loss estimates are adjusted as appropriate based on additional analysis of external loss data or other risks identified from current economic conditions and credit quality trends. The allowance also includes an amount for the estimated impairment on nonaccrual commercial loans and commercial loans modified in a troubled debt restructuring (“TDR”), whether on accrual or nonaccrual status. Consumer For consumer loans, the Company determines the allowance on a collective basis utilizing historical losses over 20 quarters to represent its best estimate of inherent loss. The Company pools loans, generally by loan class with similar risk characteristics. The allowance also includes an amount for the estimated impairment on nonaccrual consumer loans and consumer loans modified in a TDR, whether on accrual or nonaccrual status. Credit Quality Indicators Commercial We manage a consistent process for assessing commercial loan credit quality by monitoring its loan grading trends and past due statistics. All loans are subject to individual risk assessment. Our risk categories include Pass, Special Mention, Substandard, and Doubtful, each of which is defined by our banking regulatory agencies. Delinquency statistics are also an important indicator of credit quality in the establishment of our allowance for credit losses. We categorize our loans into risk categories based on relevant information about the ability of the borrower to service their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. A description of the general characteristics of the risk grades is as follows: ● Pass—These loans range from minimal credit risk to average however still acceptable credit risk. ● Special mention—A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date. ● Substandard—A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness, or weaknesses, that may jeopardize the liquidation of the debt. A substandard loan is characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. ● Doubtful—A doubtful loan has all of the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of the currently existing facts, conditions and values, highly questionable and improbable. The tables below provide a breakdown of outstanding commercial loans by risk category.

Nonperforming assets The following table shows the nonperforming assets and the related percentage of nonperforming assets to total assets and gross loans. Generally, a loan is placed on nonaccrual status when it becomes 90 days past due as to principal or interest, or when the Company believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that collection of the contractual principal or interest on the loan is doubtful. A payment of interest on a loan that is classified as nonaccrual is recognized as a reduction in principal when received.

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The Company has an established process to determine the adequacy of the allowance for loan losses that assesses the losses inherent in the portfolio. While the Company attributes portions of the allowance to specific portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio. The Company’s process involves procedures to appropriately consider the unique risk characteristics of the commercial and consumer loan portfolio segments. For each portfolio segment, impairment is measured individually for each impaired loan. The Company’s allowance levels are influenced by loan volume, loan grade or delinquency status, historic loss experience and other economic conditions. The following table summarizes the activity related to the allowance for loan losses by commercial and consumer portfolio segments: Three months ended June 30, 2018 Commercial Consumer Owner Non-owner occupied occupied Real Home (dollars in thousands) RE RE Construction Business Estate equity Construction Other Total Balance, beginning of period $ 2,680 3,366 415 3,553 3,391 1,911 256 280 15,852 Provision for loan losses 19 342 129 280 54 (438 ) 26 (12 ) 400 Loan charge-offs - (234 ) - - - (77 ) - - (311 ) Loan recoveries - 107 - 16 1 35 - - 159 Net loan charge-offs - (127 ) - 16 1 (42 ) - - (152 ) Balance, end of period $ 2,699 3,581 544 3,849 3,446 1,431 282 268 16,100 Net charge-offs to average loans (annualized) 0.04% Allowance for loan losses to gross loans 1.05% Allowance for loan losses to nonperforming loans 208.52% Three months ended June 30, 2017 Commercial Consumer Owner Non-owner occupied occupied Real Home (dollars in thousands) RE RE Construction Business Estate equity Construction Other Total Balance, beginning of period $ 3,052 2,967 334 3,823 2,830 1,619 289 373 15,287 Provision for loan losses (88 ) 255 16 139 240 (23 ) 39 (78 ) 500 Loan charge-offs - (253 ) - (120 ) - - - - (373 ) Loan recoveries - 12 - 15 (9 ) 12 - - 30 Net loan charge-offs - (241 ) - (105 ) (9 ) 12 - - (343 ) Balance, end of period $ 2,964 2,981 350 3,857 3,061 1,608 328 295 15,444 Net charge-offs to average loans (annualized) 0.11 % Allowance for loan losses to gross loans 1.19 % Allowance for loan losses to nonperforming loans 293.75 % Six months ended June 30, 2018 Commercial Consumer Owner Non-owner occupied occupied Real Home (dollars in thousands) RE RE Construction Business Estate equity Construction Other Total Balance, beginning of period $ 2,534 3,230 325 3,848 3,495 1,600 210 281 15,523 Provision for loan losses 165 478 219 (14 ) 25 (64 ) 72 19 900 Loan charge-offs - (234 ) - (119 ) (77 ) (140 ) - (34 ) (604 ) Loan recoveries - 107 - 134 3 35 - 2 281 Net loan charge-offs - (127 ) - 15 (74 ) (105 ) - (32 ) (323 ) Balance, end of period $ 2,699 3,581 544 3,849 3,446 1,431 282 268 16,100 Net charge-offs to average loans (annualized) 0.04 % Six months ended June 30, 2017 Commercial Consumer Owner Non-owner occupied occupied Real Home RE RE Construction Business Estate equity Construction Other Total Balance, beginning of period $ 2,843 2,778 295 4,123 2,780 1,475 252 309 14,855 Provision for loan losses 121 623 55 (182 ) 200 121 76 (14 ) 1,000 Loan charge-offs - (433 ) - (130 ) - - - - (563 ) Loan recoveries - 13 - 46 81 12 - - 152 Net loan charge-offs - (420 ) - (84 ) 81 12 - - (411 ) Balance, end of period $ 2,964 2,981 350 3,857 3,061 1,608 328 295 15,444 Net charge-offs to average loans (annualized) 0.03 % The following table disaggregates the allowance for loan losses and recorded investment in loans by impairment methodology.

Troubled Debt Restructurings [Abstract]
Troubled Debt Restructurings	NOTE 5 – Troubled Debt Restructurings At June 30, 2018, the Company had 28 loans totaling $10.6 million compared to 21 loans totaling $7.8 million at December 31, 2017, which were considered as TDRs. The Company considers a loan to be a TDR when the debtor experiences financial difficulties and the Company grants a concession to the debtor that it would not normally consider. Concessions can relate to the contractual interest rate, maturity date, or payment structure of the note. As part of the workout plan for individual loan relationships, the Company may restructure loan terms to assist borrowers facing financial challenges in the current economic environment. To date, the Company has restored four commercial loans previously classified as TDRs to accrual status. The following table summarizes the concession at the time of modification and the recorded investment in the Company’s TDRs before and after their modification.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	NOTE 6 – Derivative Financial Instruments The Company utilizes derivative financial instruments primarily to hedge its exposure to changes in interest rates. All derivative financial instruments are recognized as either assets or liabilities and measured at fair value. The Company accounts for all of its derivatives as free-standing derivatives and does not designate any of these instruments for hedge accounting. Therefore, the gain or loss resulting from the change in the fair value of the derivative is recognized in the Company’s statement of income during the period of change. The Company enters into commitments to originate residential mortgage loans held for sale, at specified interest rates and within a specified period of time, with clients who have applied for a loan and meet certain credit and underwriting criteria (interest rate lock commitments). These interest rate lock commitments (“IRLCs”) meet the definition of a derivative financial instrument and are reflected in the balance sheet at fair value with changes in fair value recognized in current period earnings. Unrealized gains and losses on the IRLCs are recorded as derivative assets and derivative liabilities, respectively, and are measured based on the value of the underlying mortgage loan, quoted mortgage-backed securities (“MBS”) prices and an estimate of the probability that the mortgage loan will fund within the terms of the interest rate lock commitment, net of estimated commission expenses. The Company manages the interest rate and price risk associated with its outstanding IRLCs and mortgage loans held for sale by entering into derivative instruments such as forward sales of MBS. Management expects these derivatives will experience changes in fair value opposite to changes in fair value of the IRLCs and mortgage loans held for sale, thereby reducing earnings volatility. The Company takes into account various factors and strategies in determining the portion of the mortgage pipeline (IRLCs and mortgage loans held for sale) it wants to economically hedge. The following table summarizes the Company’s outstanding financial derivative instruments at June 30, 2018 and December 31, 2017.

Fair Value Accounting

Fair Value Accounting	6 Months Ended

Fair Value Accounting [Abstract]
Fair Value Accounting	NOTE 7 – Fair Value Accounting FASB ASC 820, “Fair Value Measurement and Disclosures,” defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1 – Quoted market price in active markets Quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include certain debt and equity securities that are traded in an active exchange market. Level 2 – Significant other observable inputs Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include fixed income securities and mortgage-backed securities that are held in the Company’s available-for-sale portfolio and valued by a third-party pricing service, as well as certain impaired loans. Level 3 – Significant unobservable inputs Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. These methodologies may result in a significant portion of the fair value being derived from unobservable data. The methods of determining the fair value of assets and liabilities presented in this note are consistent with our methodologies disclosed in Note 13 of the Company’s 2017 Form 10-K, except for the valuation of loans held for investment which was impacted by the adoption of ASU 2016-01. Prior to adopting the amendments included in the standard, the Company was allowed to measure fair value under an entry price notion. The entry price notion previously applied by the Company used a discounted cash flows technique to calculate the present value of expected future cash flows for a financial instrument. The exit price notion uses the same approach, but also incorporates other factors, such as enhanced credit risk, illiquidity risk and market factors that sometimes exist in exit prices in dislocated markets. As of June 30, 2018, the technique used by the Company to estimate the exit price of the loan portfolio consists of similar procedures to those used as of December 31, 2017, but with added emphasis on both illiquidity risk and credit risk not captured by the previously applied entry price notion. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach, using the eight categories as disclosed in Note 4 – Loans and Allowance for Loan Losses. Loans are considered a Level 2 and Level 3 classification. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017.

As of June 30, 2018 (dollars in thousands) Level 1 Level 2 Level 3 Total Assets Impaired loans $ - 2,920 8,728 11,648 Other real estate owned - 23 94 117 Total assets measured at fair value on a nonrecurring basis $ - 2,943 8,822 11,765 As of December 31, 2017 Level 1 Level 2 Level 3 Total Assets Impaired loans $ - 2,685 6,084 8,769 Other real estate owned - 148 94 242 Total assets measured at fair value on a nonrecurring basis $ - 2,833 6,178 9,011 The Company had no liabilities carried at fair value or measured at fair value on a nonrecurring basis. Impaired Loans The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan may be considered impaired and an allowance for loan losses may be established. 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 the impairment in accordance with FASB ASC 310, “Receivables.” The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value 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 FASB ASC 820, “Fair Value Measurement and Disclosures,” 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 or a current appraised value, the Company considers the impaired loan as nonrecurring Level 2. The Company’s current loan and appraisal policies require the Company to obtain updated appraisals on an “as is” basis at renewal, or in the case of an impaired loan, on an annual basis, either through a new external appraisal or an appraisal evaluation. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 7% - 10% of the appraised value. For non-real estate loans, fair value of the of the impaired loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business. When an appraised value 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 considers the impaired loan as nonrecurring Level 3. The fair value of impaired loans may also be estimated using the present value of expected future cash flows to be realized on the loan, which is also considered a Level 3 valuation. These fair value estimates are subject to fluctuations in assumptions about the amount and timing of expected cash flows as well as the choice of discount rate used in the present value calculation. Other Real Estate Owned (“OREO”) OREO, consisting of properties obtained through foreclosure or in satisfaction of loans, is reported at the lower of cost or fair value, determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, adjusted for estimated selling costs (Level 2). At the time of foreclosure, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the allowance for loan losses. Gains or losses on sale and generally any subsequent adjustments to the value are recorded as a component of real estate owned activity. The unobservable inputs may vary depending on the individual assets and valuation approach. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 7% to 10% of the appraised value. When an appraised value 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 considers the OREO as nonrecurring Level 3. Fair Value of Financial Instruments Financial instruments require disclosure of fair value information, whether or not recognized in the consolidated balance sheets, when it is practical to estimate the fair value. A financial instrument is defined as cash, evidence of an ownership interest in an entity or a contractual obligation which requires the exchange of cash. Certain items are specifically excluded from the disclosure requirements, including the Company’s common stock, premises and equipment and other assets and liabilities. The estimated fair values of the Company’s financial instruments at June 30, 2018 and December 31, 2017 are as follows: June 30, 2018 Carrying Fair (dollars in thousands) Amount Value Level 1 Level 2 Level 3 Financial Assets: Other investments, at cost $ 3,059 3,059 - - 3,059 Loans 1 1,502,229 1,483,215 - - 1,483,215 Financial Liabilities: Deposits 1,567,982 1,430,788 - 1,430,788 - FHLB and other borrowings 28,600 28,792 - 28,792 - Junior subordinated debentures 13,403 14,148 - 14,148 - December 31, 2017 Carrying Fair Amount Value Level 1 Level 2 Level 3 Financial Assets: Other investments, at cost $ 4,462 4,462 - - 4,462 Loans 1 1,359,101 1,363,915 - - 1,363,915 Financial Liabilities: Deposits 1,381,123 1,269,462 - 1,269,462 - FHLB and other borrowings 67,200 67,890 - 67,890 - Junior subordinated debentures 13,403 13,166 - 13,166 - 1 Carrying amount is net of the allowance for loan losses and previously presented impaired loans. In accordance with the prospective adoption of ASU No. 2016-01, the fair value of loans as of June 30, 2018 was measured using an exit price notion. The fair value of loans as of December 31, 2017 was measured using an entry price notion.

Nature of Business and Basis of Presentation [Abstract]
Business Activity	Business Activity Southern First Bancshares, Inc. (the "Company") is a South Carolina corporation that owns all of the capital stock of Southern First Bank (the "Bank") and all of the stock of Greenville First Statutory Trust I and II (collectively, the "Trusts"). The Trusts are special purpose non-consolidated entities organized for the sole purpose of issuing trust preferred securities. The Bank's primary federal regulator is the Federal Deposit Insurance Corporation (the "FDIC"). The Bank is also regulated and examined by the South Carolina Board of Financial Institutions. The Bank is primarily engaged in the business of accepting demand deposits and savings deposits insured by the FDIC, and providing commercial, consumer and mortgage loans to the general public.
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six month periods ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 as filed with the Securities and Exchange Commission on February 28, 2018. The consolidated financial statements include the accounts of the Company and the Bank. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, “Consolidation,” the financial statements related to the Trusts have not been consolidated.
Business Segments	Business Segments In determining proper segment definition, the Company considers the materiality of a potential segment and components of the business about which financial information is available and regularly evaluated, relative to a resource allocation and performance assessment. The Company accounts for intersegment revenues and expenses as if the revenue/expense transactions were generated to third parties, that is, at current market prices. Please refer to “Note 9 – Reportable Segments” for further information on the reporting for the Company’s three business segments.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amount of income and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, real estate acquired in the settlement of loans, fair value of financial instruments, evaluating other-than-temporary-impairment of investment securities and valuation of deferred tax assets.
Reclassifications	Reclassifications Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on shareholders’ equity or net income.
Subsequent Events	Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management performed an evaluation to determine whether there have been any subsequent events since the balance sheet date and determined that no subsequent events occurred requiring accrual or disclosure.
Revenue from Contracts with Customers	Revenue from Contracts with Customers The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Our accounting policies will not change materially since the principles of revenue recognition from the Accounting Standards Update are largely consistent with existing guidance and current practices applied by our business. The following is a discussion of revenues within the scope of the new guidance: ● Service fees on deposit accounts ● ATM and debit card income - The Company earns interchange fees from debit cardholder transactions conducted through the payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder.
Income Taxes	Income Taxes On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. Authoritative guidance and interpretation by regulatory bodies is ongoing, and as such, the accounting for the effects of the Tax Act is not final and the full impact of the new regulation is still being evaluated. The accounting is expected to be complete when the 2017 U.S. corporate income tax return is filed later in 2018.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP. The new standard was effective for the Company on January 1, 2018. Adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASU 2014-09. The Company’s revenue recognition pattern for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposit accounts and gains/losses on the sale of other real estate owned, did not change significantly from current practice. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company elected to use the modified retrospective transition method which requires application of ASU 2014-09 to uncompleted contracts at the date of adoption however, periods prior to the date of adoption will not be retrospectively revised as the impact of the ASU on uncompleted contracts at the date of adoption was not material. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 7 – Fair Value Accounting for further information regarding the valuation of these loans. In February 2018, the FASB Issued (ASU 2018-02), Income Statement (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act. The Company has opted to early adopt this pronouncement by retrospective application to each period (or periods) in which the effect of the change in the tax rate under the Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings did not have a material effect on the Company’s financial statements.
Newly Issued, But Not Yet Effective Accounting Standards	Newly Issued, But Not Yet Effective Accounting Standards In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of this ASU is permitted for all entities. Adoption of ASU 2016-02 is not expected to have a material impact on the Company’s consolidated financial statements. The Company leases certain properties under operating leases that will result in the recognition of lease assets and lease liabilities on the Company’s balance sheet under the ASU. At June 30, 2018, the Company had contractual future minimum lease commitments of approximately $14.6 million, before considering renewal options that are generally present. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). Among other things, ASU 2016-13 requires 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 use forward-looking information to form 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, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 31, 2019, and interim periods within those years for public business entities that are SEC filers. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018, however, the Company does not currently plan to early adopt the ASU. We are evaluating the impact of the ASU on our consolidated financial statements. In addition to our allowance for loan losses, we will also record an allowance for credit losses on debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio’s composition and credit quality at the adoption date as well as economic conditions and forecasts at that time. In March 2017, the FASB amended the requirement in the Receivables-Nonrefundable Fees and Other Costs Topic of the Accounting Standards Codification related to the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for the premium to the earliest call date. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements. In February 2018, the FASB amended the Financial Instruments Topic of the Accounting Standards Codification. The amendments clarify certain aspects of the guidance issued in ASU 2016-01. The amendments will be effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.
