Organization, Consolidation and Presentation of Financial Statements [Abstract]
Presentation of Financial Information	Presentation of Financial Information Nature of Business: SmartFinancial, Inc. (the "Company") is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiary, SmartBank (the "Bank"). The Company provides a variety of financial services to individuals and corporate customers through its offices in East and Middle Tennessee, Alabama, and the Florida Panhandle. The Bank's primary deposit products are noninterest-bearing and interest-bearing demand deposits, savings and money market deposits, and time deposits. Its primary lending products are commercial, residential, and consumer loans. Basis of Presentation and Accounting Estimates: The accounting and financial reporting policies of SmartFinancial (the "Company") and its wholly-owned subsidiary conform to U.S. generally accepted accounting principles (“GAAP”) and reporting guidelines of banking regulatory authorities and regulators. The accompanying interim consolidated financial statements for the Company and its wholly-owned subsidiary have not been audited. All material intercompany balances and transactions have been eliminated. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of foreclosed assets and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and the fair value of assets acquired and liabilities assumed in acquisitions. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in the Company's annual report on Form 10-K for the year ended December 31, 2019. Recently Issued and Adopted Accounting Pronouncements: As of January 1, 2020, the Company adopted ASU 2019-01, Leases: Codification Improvements (“ASU 2019-01”). ASU 2019-01 provides clarification to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing essential information about leasing transactions. Specifically, ASU 2019-01 (i) allows the fair value of the underlying asset reported by lessors that are not manufacturers or dealers to continue to be its cost and not fair value as measured under the fair value definition, (ii) allows for the cash flows received for sales-type and direct financing leases to continue to be presented as results from investing, and (iii) clarifies that entities do not have to disclose the effect of the lease standard on adoption year interim amounts. The adoption of ASU 2019-01 did not have a material impact on the Company’s consolidated financial statements. Recently Issued Not Yet Effective Accounting Pronouncements: During interim periods, the Company follows the accounting policies set forth in its annual audited financial statements for the year ended December 31, 2019 as filed in its Annual Report on Form 10-K with the Securities and Exchange Commission ("SEC"). The following is a summary of recent authoritative pronouncements issued but not yet effective that could impact the accounting, reporting, and/or disclosure of financial information by the Company. In October 2019, the Financial Accounting Standards Board approved a delay for the implementation of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The Board decided that CECL will be effective for larger Public Business Entities ("PBEs") that are SEC filers, excluding Smaller Reporting Companies ("SRCs") as currently defined by the SEC, for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For calendar-year-end companies, this will be January 1, 2020. The determination of whether an entity is an SRC will be based on an entity’s most recent assessment in accordance with SEC regulations and the Company meets the regulations as a SRC. For all other entities, the Board decided that CECL will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For all entities, early adoption will continue to be permitted; that is, early adoption is allowed for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (that is, effective January 1, 2019, for calendar-year-end companies). The Company does not plan to adopt this standard early and being that the Company is an SRC, adoption is required for fiscal years beginning after December 15, 2022. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes. The amendments in this update simplify various aspects of the current guidance to promote consistent application of the standard among reporting entities by moving certain exceptions to the general principles. The amendments are effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company does not plan to adopt this standard early and adoption should not have a material impact on the Company's consolidated financial statements. In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. Under Accounting Standards Codification 310-40, “Receivables – Troubled Debt Restructurings by Creditors,” (“ASC 310-40”), a restructuring of debt constitutes a troubled debt restructuring (“TDR”) if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. As of March 31, 2020, the Bank had provided modifications to approximately $70.1 million in loans, per the guidance stated above. This interagency guidance could have a material impact on the Company’s financial statements; however, this impact cannot be quantified at this time. Reclassifications:

Business Combinations [Abstract]
Business Combinations	Business Combinations Acquisition of Progressive Financial Inc. On March 1, 2020, the Company completed the merger of Progressive Financial Group, Inc., a Tennessee corporation ("PFG"), pursuant to an Agreement and Plan of Merger dated October 29, 2019 (the "Merger Agreement"). In connection with the merger, the Company acquired $301 million of assets and assumed $272 million of liabilities. Pursuant to the Merger Agreement, each outstanding share of Progressive common stock was converted into and cancelled in exchange to the right to receive $474.82 in cash, and 62.3808 shares of SmartFinancial common stock. SmartFinancial issued 1,292,578 shares of SmartFinancial common stock and paid $9.8 million in cash as consideration for the Merger. The fair value of consideration paid exceeded the fair value of the identifiable assets and liabilities acquired and resulted in the establishment of goodwill in the amount of $8.3 million, representing the intangible value of Progressive's business and reputation within the markets it served. None of the goodwill recognized is expected to be deductible for income tax purposes. The Company is amortizing the related core deposit intangible of $1.4 million using the effective yield method over 120 months (10 years), which represents the expected useful life of the asset. The Company's operating results for the period ended March 31, 2020, include the operating results of the acquired business for the period subsequent to the merger date of March 1, 2020. The purchased assets and assumed liabilities were recorded at their acquisition date fair values and are summarized in the table below (in thousands) .

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding and dilutive common share equivalents using the treasury stock method. Dilutive common share equivalents include common shares issuable upon exercise of outstanding stock options and restricted stock. The effect from the stock options and restricted stock on incremental shares from the assumed conversions for net income per share-basic and net income per share-diluted are presented below. There were 64 thousand antidilutive shares for the period ended March 31, 2020, and none for the period ended March 31, 2019.

A determination as to whether a security's decline in fair value is other-than-temporary takes into consideration numerous factors and the relative significance of any single factor can vary by security. Some factors the Company may consider in the other-than-temporary impairment analysis include the length of time and extent to which the security has been in an unrealized loss position, changes in security ratings, financial condition and near-term prospects of the issuer, as well as security and industry specific economic conditions. Based on this evaluation, the Company concluded that any unrealized losses at March 31, 2020, represented a temporary impairment, as these unrealized losses are primarily attributable to changes in interest rates and current market conditions, and not credit deterioration of the issuers. As of March 31, 2020, the Company does not intend to sell any of the securities, does not expect to be required to sell any of the securities, and expects to recover the entire amortized cost of all of the securities.

The restructuring of a loan is considered a TDR if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession. In assessing whether or not a borrower is experiencing financial difficulties, the Company considers information currently available regarding the financial condition of the borrower. This information includes, but is not limited to, whether (i) the debtor is currently in payment default on any of its debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the debtor has declared or is in the process of declaring bankruptcy; and (iv) the debtor's projected cash flow is sufficient to satisfy contractual payments due under the original terms of the loan without a modification. The Company considers all aspects of the modification to loan terms to determine whether or not a concession has been granted to the borrower. Key factors considered by the Company include the debtor's ability to access funds at a market rate for debt with similar risk characteristics, the significance of the modification relative to unpaid principal balance or collateral value of the debt, and the significance of a delay in the timing of payments relative to the original contractual terms of the loan. The most common concessions granted by the Company generally include one or more modifications to the terms of the debt, such as (i) a reduction in the interest rate for the remaining life of the debt; (ii) an extension of the maturity date at an interest rate lower than the current market rate for new debt with similar risk; (iii) a temporary period of interest-only payments; and (iv) a reduction in the contractual payment amount for either a short period or remaining term of the loan. As of March 31, 2020, and December 31, 2019, management had approximately $9 thousand and $61 thousand, respectively, in loans that met the criteria for TDR, none of which were on nonaccrual. A loan is placed back on accrual status when both principal and interest are current and it is probable that the Company will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement. There was one loan that was modified as a TDR during the three month period ended March 31, 2020, and no loans were modified during the three month period ended March 31, 2019. There were no loans that were modified as troubled debt restructurings during the past three months and for which there was a subsequent payment default. Foreclosure Proceedings and Balances : As of March 31, 2020, there were seven properties secured by real estate included in other real estate owned and there were no consumer mortgage loans collateralized by residential real estate property that were in the process of foreclosure.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing and depository needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amount recognized on the balance sheet. The majority of all commitments to extend credit are variable rate instruments while the standby letters of credit are primarily fixed rate instruments. The Company's exposure to credit loss is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for on-balance sheet instruments. A summary of the Company’s total contractual amount for all off-balance sheet commitments are as follows (in thousands): March 31, December 31, 2020 2019 Commitments to extend credit $ 419,287 $ 384,411 Standby letters of credit 22,994 11,727 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 are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial properties. Standby letters of credit issued by the Company are conditional commitments to guarantee the performance of a customer to a third party. Those letters of credit are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Collateral held varies and is required in instances which the Company deems necessary. At March 31, 2020 and December 31, 2019, the carrying amount of liabilities related to the Company's obligation to perform under standby letters of credit was insignificant. The Company is subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. Management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against the Company will be material to the Company's consolidated financial position. On an on-going basis the Company assesses any potential liabilities or contingencies in connection with such legal proceedings. For those matters where it is deemed probable that the Company will incur losses and the amount of the losses can be reasonably estimated, the Company would record an expense and corresponding liability in its consolidated financial statements.

Fair Value Disclosures

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures Determination of Fair Value: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the “Fair Value Measurements and Disclosures” ASC Topic 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. ASC Topic 820 provides a consistent definition of fair value, which focuses on exit price in an orderly transaction between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact business at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. In accordance with this guidance, the Company groups its financial assets and financial liabilities generally measured 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. Level 1 - Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on 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 asset or liability. Level 3 - Valuation is based on 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 determination of fair value requires significant management judgment or estimation. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis are as follows (in thousands) : Description Fair Value Quoted Prices in Significant Significant March 31, 2020: Assets: Securities available-for-sale: U.S. Government-sponsored enterprises (GSEs) $ 17,045 $ — $ 17,045 $ — Municipal securities 83,317 — 83,317 — Other debt securities 5,462 — 5,462 — Mortgage-backed securities (GSEs) 95,178 — 95,178 — Total securities available-for-sale $ 201,002 $ — $ 201,002 $ — Liabilities: Derivative financial instruments $ 6,885 $ — $ 6,885 $ — December 31, 2019: Assets: Securities available-for-sale: U.S. Government-sponsored enterprises (GSEs) $ 19,000 $ — $ 19,000 $ — Municipal securities 64,391 — 64,391 — Other debt securities 3,470 — 3,470 — Mortgage-backed securities (GSEs) 91,487 — 91,487 — Total securities available-for-sale $ 178,348 $ — $ 178,348 $ — Liabilities: Derivative financial instruments $ 3,446 — $ 3,446 — In the periods presented, there were no transfers between Level 1 and Level 2 in the fair value hierarchy. Assets Measured at Fair Value on a Nonrecurring Basis: Under certain circumstances management makes adjustments to fair value for assets and liabilities although they are not measured at fair value on an ongoing basis. The following tables present the financial instruments carried on the consolidated balance sheets by caption and by level in the fair value hierarchy, for which a nonrecurring change in fair value has been recorded (in thousands) : Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) March 31, 2020: Impaired loans $ 2,262 $ — $ — $ 2,262 Other real estate owned 5,894 — — 5,894 December 31, 2019: Impaired loans $ 2,185 $ — $ — $ 2,185 Other real estate owned 1,757 — — 1,757 For Level 3 assets measured at fair value on a non-recurring basis, the significant unobservable inputs used in the fair value measurements are presented below (dollars in thousands) : Fair Value Valuation Significant Other Weighted March 31, 2020: Impaired loans $ 2,262 Appraisal and cashflow Appraisal and cashflow discounts 20 % Other real estate owned 5,894 Appraisal Appraisal discounts 27 % December 31, 2019: Impaired loans $ 2,185 Appraisal Appraisal and cashflow discounts 22 % Other real estate owned 1,757 Appraisal Appraisal discounts 29 % Impaired loans: Loans considered impaired under ASC 310-10-35, Receivables , are loans for which, based on current information and events, it is probable that the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreement. An impaired loan can be measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent. The fair value of impaired loans was measured based on the value of the collateral securing these loans or the discounted cash flows of the loans, as applicable. Impaired loans are classified within Level 3 of the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory, and/or accounts receivable. The Company determines the value of the collateral based on independent appraisals performed by qualified licensed appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised values are discounted for costs to sell and may be discounted further based on management’s historical knowledge, changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts by management are subjective and are typically significant unobservable inputs for determining fair value. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors discussed above. Other real estate owned: Other real estate owned, consisting of properties obtained through foreclosure or in satisfaction of loans, are initially recorded at fair value less estimated costs to sell upon transfer of the loans to other real estate. Subsequently, other real estate is carried at the lower of carrying value or fair value less costs to sell. Fair values are generally based on third party appraisals of the property and are classified within Level 3 of the fair value hierarchy. The appraisals are sometimes further discounted based on management’s historical knowledge, and/or changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts are typically significant unobservable inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less estimated costs to sell, a loss is recognized in noninterest expense. Carrying value and estimated fair value: The carrying amount and estimated fair value of the Company’s financial instruments are as follows (in thousands) : Fair Value Measurements Using Carrying Level 1 Level 2 Level 3 Estimated March 31, 2020: Assets: Cash and cash equivalents $ 309,089 $ 309,089 $ — $ — $ 309,089 Securities available-for-sale 201,002 — 201,002 — 201,002 Other investments 14,113 N/A N/A N/A N/A Loans, net 2,131,861 — — 2,115,550 2,115,550 Liabilities: Noninterest-bearing demand deposits 431,781 — 431,781 — 431,781 Interest-bearing demand deposits 444,141 — 444,141 — 444,141 Money market and savings deposits 730,392 — 730,392 — 730,392 Time deposits 735,616 — 739,277 — 739,277 Securities sold under agreements to repurchase 6,164 — 6,164 — 6,164 Federal Home Loan Bank advances and other borrowings 125,439 — 124,797 — 124,797 Subordinated debt 39,283 — — 34,379 34,379 Derivative financial instruments 6,885 — 6,885 — 6,885 December 31, 2019: Assets: Cash and cash equivalents $ 183,971 $ 183,971 $ — $ — $ 183,971 Securities available-for-sale 178,348 — 178,348 — 178,348 Other investments 12,913 N/A N/A N/A N/A Loans, net 1,893,005 — — 1,879,825 1,879,825 Liabilities: Noninterest-bearing demand deposits 364,155 — 364,155 — 364,155 Interest-bearing demand deposits 380,234 — 380,234 — 380,234 Money market and savings deposits 623,284 — 623,284 — 623,284 Time deposits 679,541 — 681,902 — 681,902 Securities sold under agreements to repurchase 6,184 — 6,184 — 6,184 Federal Home Loan Bank advances and other borrowings 25,439 — 24,845 — 24,845 Subordinated debt 39,261 — — 35,868 35,868 Derivative financial instruments 3,446 — 3,446 — 3,446 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. 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 unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative net investment hedge instrument as well as the offsetting gain or loss on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. The Company utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate tax-exempt callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. The Company has elected early adoption of ASU 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities, which allows such partial term hedge designations. A summary of the Company's fair value hedge relationships for the periods presented are as follows (dollars in thousands) : Liability derivatives Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Amount Estimated Fair Value March 31, 2020: Interest rate swap agreements - securities Other liabilities 7.95 3.09% 3 month LIBOR $ 36,000 $ (6,885) December 31, 2019: Interest rate swap agreements - securities Other liabilities 8.20 3.09% 3 month LIBOR $ 36,000 $ (3,446) The effects of the Company's fair value hedge relationships reported in interest income on tax-exempt available-for-sale securities on the consolidated income statement were as follows (in thousands) : Three Months Ended March 31, 2020 2019 Interest income on tax-exempt securities $ 440 $ 456 Effects of fair value hedge relationships (157) (32) Reported interest income on tax-exempt securities $ 283 $ 424 Three Months Ended March 31, Gain (loss) on fair value hedging relationship 2020 2019 Interest rate swap agreements - securities: Hedged items $ 6,885 2,063 Derivative designated as hedging instruments (6,885) (2,063) The following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges (in thousands) : Line item on the balance sheet Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets March 31, 2020: Securities available-for-sale $ 46,060 $ 6,885 December 31, 2019: Securities available-for-sale $ 42,710 $ 3,446

Leases [Abstract]
Leases	Leases A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02 and all subsequent ASUs that modified this topic (collectively referred to as "Topic 842"). For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee. Substantially all of the leases in which the Company is the lessee are comprised of real estate for branches and office space with terms extending through 2034. All of our leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated balance sheet. With the adoption of Topic 842, operating lease agreements are required to be recognized on the consolidated balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. The following table represents the consolidated balance sheet classification of the Company’s ROU assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the consolidated balance sheet (in thousands) : March 31, December 31, Classification 2020 2019 Assets: Operating lease right-of-use assets Other assets $ 5,493 $ 5,470 Liabilities: Operating lease liabilities Other liabilities $ 5,508 $ 5,479 The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. As of March 31, 2020, the weighted average remaining lease term was 11.17 years and the weighted average discount rate was 2.78%. The following table represents lease costs and other lease information, in thousands. As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance (in thousands) .

Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgements by regulators. Failure to meet capital requirements can initiate regulatory action. Under Basel III rules, the Company must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is 2.50%. At March 31, 2020, and 2019, the Company and the Bank exceeded the minimum regulatory requirements and exceeded the threshold for the "well capitalized" regulatory classification. Regulatory Restrictions on Dividends: Pursuant to Tennessee banking law, the Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (TDFI), pay any dividends to the Company in a calendar year in excess of the total of the Bank's retained net income for that year plus the retained net income for the preceding two years. Under Tennessee corporate law, the Company is not permitted to pay dividends if, after giving effect to such payment, it would not be able to pay its debts as they become due in the usual course of business or its total assets would be less than the sum of its total liabilities plus any amounts needed to satisfy any preferential rights if it were dissolving. In addition, in deciding whether or not to declare a dividend of any particular size, the Company's board of directors must consider its and the Bank's current and prospective capital, liquidity, and other needs. In addition to state law limitations on the Company's ability to pay dividends, the Federal Reserve imposes limitations on the Company's ability to pay dividends. Federal Reserve regulations limit dividends, stock repurchases and discretionary bonuses to executive officers if the Company's regulatory capital is below the level of regulatory minimums plus the applicable capital conservation buffer. During the three months ended March 31, 2020, the Bank paid $7.5 million in dividends to the Company. As of March 31, 2020, the Bank could pay approximately $52.0 million of additional dividends to the Company without prior approval of the Commissioner of the TDFI. Since the fourth quarter of 2019, the Company has paid a quarterly common stock dividend of $0.05 per share. The amount and timing of all future dividend payments by the Company, if any, is subject to discretion of the Company's board of directors and will depend on the Company's earnings, capital position, financial condition and other factors, including new regulatory capital requirements, as they become known to the Company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business: SmartFinancial, Inc. (the "Company") is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiary, SmartBank (the "Bank"). The Company provides a variety of financial services to individuals and corporate customers through its offices in East and Middle Tennessee, Alabama, and the Florida Panhandle. The Bank's primary deposit products are noninterest-bearing and interest-bearing demand deposits, savings and money market deposits, and time deposits. Its primary lending products are commercial, residential, and consumer loans.
Basis of Presentation and Accounting Estimates	Basis of Presentation and Accounting Estimates: The accounting and financial reporting policies of SmartFinancial (the "Company") and its wholly-owned subsidiary conform to U.S. generally accepted accounting principles (“GAAP”) and reporting guidelines of banking regulatory authorities and regulators. The accompanying interim consolidated financial statements for the Company and its wholly-owned subsidiary have not been audited. All material intercompany balances and transactions have been eliminated. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of foreclosed assets and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and the fair value of assets acquired and liabilities assumed in acquisitions. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in the Company's annual report on Form 10-K for the year ended December 31, 2019.
Recently Issued and Adopted Accounting Pronouncements; Recently Issued Not Yet Effective Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements: As of January 1, 2020, the Company adopted ASU 2019-01, Leases: Codification Improvements (“ASU 2019-01”). ASU 2019-01 provides clarification to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing essential information about leasing transactions. Specifically, ASU 2019-01 (i) allows the fair value of the underlying asset reported by lessors that are not manufacturers or dealers to continue to be its cost and not fair value as measured under the fair value definition, (ii) allows for the cash flows received for sales-type and direct financing leases to continue to be presented as results from investing, and (iii) clarifies that entities do not have to disclose the effect of the lease standard on adoption year interim amounts. The adoption of ASU 2019-01 did not have a material impact on the Company’s consolidated financial statements. Recently Issued Not Yet Effective Accounting Pronouncements: During interim periods, the Company follows the accounting policies set forth in its annual audited financial statements for the year ended December 31, 2019 as filed in its Annual Report on Form 10-K with the Securities and Exchange Commission ("SEC"). The following is a summary of recent authoritative pronouncements issued but not yet effective that could impact the accounting, reporting, and/or disclosure of financial information by the Company. In October 2019, the Financial Accounting Standards Board approved a delay for the implementation of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The Board decided that CECL will be effective for larger Public Business Entities ("PBEs") that are SEC filers, excluding Smaller Reporting Companies ("SRCs") as currently defined by the SEC, for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For calendar-year-end companies, this will be January 1, 2020. The determination of whether an entity is an SRC will be based on an entity’s most recent assessment in accordance with SEC regulations and the Company meets the regulations as a SRC. For all other entities, the Board decided that CECL will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For all entities, early adoption will continue to be permitted; that is, early adoption is allowed for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (that is, effective January 1, 2019, for calendar-year-end companies). The Company does not plan to adopt this standard early and being that the Company is an SRC, adoption is required for fiscal years beginning after December 15, 2022. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes. The amendments in this update simplify various aspects of the current guidance to promote consistent application of the standard among reporting entities by moving certain exceptions to the general principles. The amendments are effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company does not plan to adopt this standard early and adoption should not have a material impact on the Company's consolidated financial statements. In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. Under Accounting Standards Codification 310-40, “Receivables – Troubled Debt Restructurings by Creditors,” (“ASC 310-40”), a restructuring of debt constitutes a troubled debt restructuring (“TDR”) if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. As of March 31, 2020, the Bank had provided modifications to approximately $70.1 million in loans, per the guidance stated above. This interagency guidance could have a material impact on the Company’s financial statements; however, this impact cannot be quantified at this time.
Reclassifications	Reclassifications:Certain captions and amounts in the 2019 consolidated financial statements were reclassified to conform to the 2020 financial statement presentation. These reclassifications had no impact on net income or shareholders' equity as previously reported.
Earnings Per Share	Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding and dilutive common share equivalents using the treasury stock method. Dilutive common share equivalents include common shares issuable upon exercise of outstanding stock options and restricted stock.
