Organization, Consolidation and Presentation of Financial Statements [Abstract]
Presentation of Financial Information	Presentation of Financial Information Interim Financial Information (Unaudited): The financial information in this report for March 31, 2019 and March 31, 2018 has not been audited. The information included herein should be read in conjunction with the Company’s annual consolidated financial statements and footnotes included in the Company's most recent Annual Report on Form 10-K. The consolidated financial statements presented herein conform to U.S. generally accepted accounting principles and to general industry practices. In the opinion of SmartFinancial’s management, the accompanying interim financial statements contain all material adjustments necessary to present fairly the Company's financial condition, the results of operations, and cash flows for the interim period. Results for interim periods are not necessarily indicative of the results to be expected for a full year. Basis of Presentation and Accounting Estimates: All adjustments consisting of normal recurring accruals that in the opinion of management are necessary for a fair presentation of the financial position and the results of operations for the periods covered by the report have been included. The accompanying unaudited consolidated financial statements and related notes should be read in conjunction with those appearing in the most recent Annual Report previously filed on Form 10-K. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the U.S, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet, and reported amounts of revenues and expenses during the reporting period. 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, the valuation of foreclosed assets and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and business combination elements (Day 1 and Day 2 Valuation). Recently Issued and Adopted Accounting Pronouncements: As of January 1, 2019, the Company adopted certain accounting standard updates related to accounting for leases (Topic 842 - Leases), primarily Accounting Standards Update ASU 2016-02 and subsequent updates. Among other things, these updates require lessees to recognize a lease liability, measured on a discounted basis, related to the lessee's obligation to make lease payments arising under a lease contract; and a right-of-use asset related to the lessee's right to use, or control the use of, a specified asset for the lease term. The updates did not significantly change lease accounting requirements applicable to lessors and did not significantly impact the Company's consolidated financial statements in relation to contracts whereby the Company acts as a lessor. The Company adopted the updates using a modified-retrospective transition approach and recognized right-of-use lease assets and related lease liabilities totaling $2.3 million each as of January 1, 2019. As of March 31, 2019, right-of-use lease assets and related lease liabilities totaled $2.2 million each. In February 2016, the FASB issued ASU No. 2016-02, Leases . Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee’s obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard. All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. All entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. As the Company elected the transition option provided in ASU No. 2018-11 (see below), the modified retrospective approach was applied on January 1, 2019. Note 1. Presentation of Financial Information, Continued Recently Issued and Adopted Accounting Pronouncements (continued): The Company also elected certain relief options offered in ASU 2016-02 including the package of practical expedients, the option not to separate lease and non-lease components and instead to account for them as a single lease component, and the option not to recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). We elected to apply certain practical adoption expedients provided under the updates whereby we did not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. The Company did not elect the hindsight practical expedient, which allows entities to use hindsight when determining lease term and impairment of right-of-use assets. The Company has several lease agreements, such as branch locations or office space, which are considered operating leases, and therefore, were not previously recognized on the Company’s consolidated balance sheet. The new guidance requires these lease agreements to be recognized on the consolidated balance sheet as a right-of-use asset and a corresponding lease liability. The new guidance did not have a material impact on the consolidated statements of income or the consolidated statements of cash flows. See Note 8 Leases for more information. In July 2018, the FASB issued ASU No. 2018-11, Leases - Targeted Improvements to provide entities with relief from the costs of implementing certain aspects of the new leasing standard, ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02 (January 1, 2019 for the Company). The Company adopted ASU 2018-11 on its required effective date of January 1, 2019 and elected both transition options mentioned above. As of January 1, 2019, the Company adopted ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . The ASU expands the scope of Topic 718, Compensation-Stock Compensation (which previously only included payments to employees), to include share-based payment transactions for acquiring goods and services from non-employees. This required entities to apply the requirements of Topic 718 to non-employee awards, except for specific guidance on inputs to an option pricing model and the attribution of cost (i.e., the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). Additionally, the amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in the grantor’s own operations by issuing share-based payment awards, and clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer, or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. As of January 1, 2019, the Company adopted ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The premium on individual callable debt securities shall be amortized to the earliest call date. This guidance does not apply to securities for which prepayments are estimated on a large number of similar loans where prepayments are probable and reasonably estimable. The adoption of this ASU 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, 2018 as filed with the Securities and Exchange Commission. The following is a summary of recent authoritative pronouncements issued since December 31, 2018 but not yet effective that could impact the accounting, reporting, and/or disclosure of financial information by the Company . Note 1. Presentation of Financial Information, Continued Recently Not Yet Effective Accounting Pronouncements (continued): In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The ASU changed the credit loss model on financial instruments measured at amortized cost, available for sale securities and certain purchased financial instruments. Credit losses on financial instruments measured at amortized cost will be determined using a current expected credit loss model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. Purchased financial assets with more-than-insignificant credit deterioration since origination ("PCD assets" which are currently named "PCI Loans") measured at amortized cost will have an allowance for credit losses established at acquisition as part of the purchase price. Subsequent increases or decreases to the allowance for credit losses on PCD assets will be recognized in the income statement. Interest income should be recognized on PCD assets based on the effective interest rate, determined excluding the discount attributed to credit losses at acquisition. Credit losses relating to available-for-sale debt securities will be recognized through an allowance for credit losses. The amount of the credit loss is limited to the amount by which fair value is below amortized cost of the available-for-sale debt security. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years for the Company and other SEC filers. Early adoption is permitted and if early adopted, all provisions must be adopted in the same period. The amendments should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the period adopted. A prospective approach is required for securities with other than temporary impairment recognized prior to adoption. The Company is continuing its implementation efforts through its company-wide implementation team. The implementation team meets periodically to discuss the latest developments and ensure progress is being made. The team also keeps current on evolving interpretations and industry practices related to ASU 2016-13 via webcasts, publications, conferences, and peer bank meetings. The team continues to evaluate and validate data resources and different loss methodologies. The Company’s preliminary evaluation indicates the provisions of ASU No. 2016-13 are expected to impact the Company’s consolidated financial statements, in particular an increase to the level of the reserve for credit losses. However, the Company continues to evaluate the extent of the potential impact. The guidance of ASU 2016-13 was recently amended by ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, which changed the effective date for non-public companies and clarified that operating lease receivables are not within the scope of the standard. Reclassifications: Certain captions and amounts in the 2018 consolidated financial statements were reclassified to conform to the 2019 presentation and these reclassifications had no impact on net income or shareholders' equity as previously reported. Earnings per common share: Basic earnings per common share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance (excluding tax impact). Potential common shares that may be issued by the Company relate solely to outstanding stock options, determined using the treasury stock method, and restricted stock awards, determined by the fair value of the Company's stock on date of grant.

For the three months ended March 31, 2019, there was one security called/redeemed for $5 million . Note 3. Securities, Continued The amortized cost and estimated fair value of securities at March 31, 2019 , by contractual maturity for non-mortgage backed securities are shown below (in thousands). Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Securities, Continued At March 31, 2019 , the categories of temporarily impaired securities, and management’s evaluation of those securities, are as follows: U.S. Government-sponsored enterprises : At March 31, 2019 , 8 (or eight) investments in U.S. GSE securities had unrealized losses. These unrealized losses related principally to changes in market interest rates. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Bank does not intend to sell the investments and it is more likely than not that the Bank will not be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Bank does not consider these investments to be other-than temporarily impaired at March 31, 2019 . Municipal securities : At March 31, 2019 , 8 (or eight) investments in obligations of municipal securities had unrealized losses. The Bank believes the unrealized losses on those investments were caused by the interest rate environment and do not relate to the underlying credit quality of the issuers. Because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Bank does not consider these investments to be other-than temporarily impaired at March 31, 2019 . Other debt securities : At March 31, 2019 , 1 (or one) investment in other debt securities had unrealized losses. The Bank believes the unrealized loss on this investment was caused by the interest rate environment and does not relate to the underlying credit quality of the issuer. Because the Bank does not intend to sell the investment and it is not more likely than not that the Bank will be required to sell the investment before recovery of its amortized cost bases, which may be maturity, the Bank does not consider this investment to be other-than temporarily impaired at March 31, 2019 . Mortgage-backed securities : At March 31, 2019 , 68 (or sixty-eight) investments in residential mortgage-backed securities had unrealized losses. This impairment is believed to be caused by the current interest rate environment. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Because the decline in market value is attributable to the current interest rate environment and not credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Bank does not deem these investments to be other-than-temporarily impaired at March 31, 2019 .

For purposes of the disclosures required pursuant to the adoption of ASC 310, the loan portfolio was disaggregated into segments. A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. There are five loan portfolio segments that include commercial real estate, consumer real estate, construction and land development, commercial and industrial, and consumer and other. Note 4.

Loans and Allowance for Loan Losses, Continued Past Due Loans: A loan is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement. Generally, management places a loan on nonaccrual when there is a clear indicator that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due.

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. Note 4. Loans and Allowance for Loan Losses, Continued Troubled Debt Restructurings (continued): 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, 2019 and December 31, 2018 , management had approximately $62 thousand and $116 thousand, respectively, in loans that met the criteria for restructured, 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 management will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement. There were no loans that were modified as troubled debt restructurings during the three month period ended March 31, 2019 and 2018. 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, 2019, there was no residential real estate included in foreclosed assets and there were no consumer mortgage loans collateralized by residential real estate property that were in the process of foreclosure. Purchased Credit Impaired Loans: The Company has acquired loans where there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans as of as of March 31, 2019 and December 31, 2018 is as follows (in thousands): March 31, 2019 December 31, 2018 Commercial real estate $ 24,226 $ 24,849 Consumer real estate 10,464 11,108 Construction and land development 5,724 5,731 Commercial and industrial 5,369 5,824 Consumer and other 721 892 Total loans 46,504 48,404 Less remaining purchase discount (13,636 ) (14,246 ) Total loans, net of purchase discount 32,868 34,158 Less: Allowance for loan losses (54 ) — Carrying amount, net of allowance $ 32,814 $ 34,158 Activity related to the accretable yield on loans acquired with deteriorated credit quality is as follows for the three month periods ended March 31, 2019 and 2018 (in thousands): Three Months Ended March 31, 2019 2018 Accretable yield, beginning of period $ 7,052 $ 9,287 Additions — — Accretion income (1,254 ) (1,101 ) Reclassification to accretable 1,035 262 Other changes, net 1,811 (668 ) Accretable yield $ 8,644 $ 7,780

Commitments and Contingent Liab

Commitments and Contingent Liabilities	3 Months Ended
	Mar. 31, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Loan Commitments: 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 in the balance sheets. 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 Bank’s total contractual amount for all off-balance sheet commitments at March 31, 2019 is as follows: Commitments to extend credit $ 356.0 million Standby letters of credit $ 14.6 million 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, 2019 and December 31, 2018, the carrying amount of liabilities related to the Company's obligation to perform under standby letters of credit was insignificant. The Company has not been required to perform on any standby letters of credit, and the Company has not incurred any losses on standby letters of credit for the period ending March 31, 2019. Contingencies: In the normal course of business, the Company may become involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material effect on the Company's consolidated financial statements.

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 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. Note 6. Fair Value Disclosures, Continued Fair Value Hierarchy: 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. Measurements of Fair Value: Assets and liabilities recorded at fair value on a recurring basis are as follows (in thousands): Balance as of Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Debt securities available-for-sale: U.S. Government-sponsored enterprises (GSEs) $ 38,828 $ — $ 38,828 $ — Mortgage-backed securities 99,582 — 99,582 — Other debt securities 935 — 935 — Municipal securities 58,928 — 58,928 — Total securities available-for-sale $ 198,273 $ — $ 198,273 $ — Derivative financial instruments $ 2,063 $ — $ 2,063 $ — Balance as of Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Debt securities available-for-sale: U.S. Government-sponsored enterprises (GSEs) $ 43,503 $ — $ 43,503 $ — Mortgage-backed securities 102,114 — 102,114 — Other debt securities 910 — 910 — Municipal securities 55,161 — 55,161 — Total securities available-for-sale $ 201,688 $ — $ 201,688 $ — Derivative financial instruments $ 1,174 — $ 1,174 — The Company has no assets or liabilities whose fair values are measured on a recurring basis using Level 3 inputs. Additionally, there were no transfers between Level 1 and Level 2 in the fair value hierarchy. Note 6. Fair Value Disclosures, Continued 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): Balance as of Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Impaired loans $ 3,860 $ — $ — $ 3,860 Foreclosed assets 2,066 — — 2,066 Balance as of Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Impaired loans $ 671 $ — $ — $ 671 Foreclosed assets 2,495 — — 2,495 For Level 3 assets measured at fair value on a non-recurring basis as of March 31, 2019 and December 31, 2018, the significant unobservable inputs used in the fair value measurements are presented below (in thousands). Balance as of Valuation Significant Other Weighted Impaired loans $ 3,860 Appraisal and Cashflow Appraisal and Cashflow Discounts 7 % Foreclosed assets 2,066 Appraisal Appraisal Discounts 20 % Balance as of Valuation Significant Other Weighted Impaired loans $ 671 Appraisal Appraisal Discounts 44 % Foreclosed assets 2,495 Appraisal Appraisal Discounts 23 % 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 were 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. Note 6. Fair Value Disclosures, Continued Assets Measured at Fair Value on a Nonrecurring Basis (continued): Foreclosed assets: Foreclosed assets, 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 at March 31, 2019 and December 31, 2018 are as follows (in thousands): March 31, 2019 Fair Value Measurements Using Carrying Amount Level 1 Level 2 Level 3 Estimated Fair Value Assets: Cash and cash equivalents $ 132,994 132,994 — — $ 132,994 Securities available-for-sale 198,273 — 198,273 — 198,273 Restricted investments 12,398 N/A N/A N/A N/A Loans, net 1,831,865 — — 1,824,680 1,824,680 Liabilities: Noninterest-bearing demand deposits 329,095 — 329,095 — 329,095 Interest-bearing demand deposits 331,629 — 331,629 — 331,629 Money Market and Savings deposits 698,431 — 698,431 — 698,431 Time deposits 635,175 — 635,272 — 635,272 Securities sold under agreements to repurchase 7,070 — 7,070 — 7,070 Federal Home Loan Bank advances and other borrowings 8,605 — 8,605 — 8,605 Subordinated debt 39,198 — — 37,606 37,606 Derivative financial instruments 2,063 — 2,063 — 2,063 Note 6. Fair Value Disclosures, Continued Carrying value and estimated fair value (continued): December 31, 2018 Fair Value Measurements Using Carrying Amount Level 1 Level 2 Level 3 Estimated Fair Value Assets: Cash and cash equivalents $ 115,822 115,822 — — $ 115,822 Securities available-for-sale 201,688 — 201,688 — 201,688 Restricted investments 11,499 N/A N/A N/A N/A Loans, net 1,768,964 — — 1,766,838 1,766,838 Liabilities: Noninterest-bearing demand deposits 319,861 — 319,861 — 319,861 Interest-bearing demand deposits 311,482 — 311,482 — 311,482 Money Market and Savings deposits 641,945 — 641,945 — 641,945 Time deposits 648,675 — 649,169 — 649,169 Securities sold under agreements to repurchase 11,756 — 11,756 — 11,756 Federal Home Loan Bank advances and other borrowings 11,243 — 11,243 — 11,243 Subordinated debt 39,177 — — 39,190 39,190 Derivative financial instruments 1,174 — 1,174 — 1,174 Limitations: Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on many judgments. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes and premises and equipment. In addition, the tax ramifications related to the realization of 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 derivatives not designated as hedges, the gain or loss is recognized in current period earnings. Derivatives designated as fair value hedges : For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain 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 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 FASB ASU 2017-12, which allows such partial term hedge designations. In September 2018, December 2018, and February 2019, the Company entered into sixteen swap transactions with a notional amount of $36 million designated as fair value hedges. These derivatives are intended to protect against the effects of changing interest rates on the fair values of fixed rate securities. A summary of the Company's fair value hedge relationships as of March 31, 2019 and December 31, 2018 are as follows (in thousands): March 31, 2019 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Amount Estimated Fair Value Liability derivatives Interest rate swap agreements - securities Other liabilities 8.95 3.09% 3 month LIBOR $36,000 -$2,063 December 31, 2018 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Amount Estimated Fair Value Liability derivatives Interest rate swap agreements - securities Other liabilities 9.23 3.10% 3 month LIBOR $35,000 -$1,174 Note 7.

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 Leases (Topic 842) and all subsequent ASUs that modified Topic 842. For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee. Lessee Accounting : Substantially all of the leases in which the Company is the lessee are comprised of real estate property for branches and office space with terms extending through 2033. Substantially 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 (dollars in thousands): Lease Right-of-Use Assets Classification March 31, 2019 Operating lease right-of-use assets Operating lease right-of-use assets $2,215 Lease Liabilities Operating lease liabilities Operating lease liabilities $2,222 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, 2019, the weighted average remaining lease term was 7.81 years and the weighted average discount rate was 3.24% . Note 8. Leases, Continued 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. Three Months Ended Lease Costs March 31, 2019 Operating lease costs $ 146 Short term lease costs 36 Variable lease costs 23 Total 205 Other information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 139 Future minimum payments for operating leases with initial or remaining terms of one year or more as of March 31, 2019 were as follows (in thousands): Amounts March 31, 2020 $ 533 March 31, 2021 531 March 31, 2022 332 March 31, 2023 213 March 31, 2024 107 Thereafter 842 Total future minimum lease payments 2,558 Amounts representing interest (336 ) Present value of net future minimum lease payments $ 2,222

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Financial Information (Unaudited)	Interim Financial Information (Unaudited): The financial information in this report for March 31, 2019 and March 31, 2018 has not been audited. The information included herein should be read in conjunction with the Company’s annual consolidated financial statements and footnotes included in the Company's most recent Annual Report on Form 10-K. The consolidated financial statements presented herein conform to U.S. generally accepted accounting principles and to general industry practices. In the opinion of SmartFinancial’s management, the accompanying interim financial statements contain all material adjustments necessary to present fairly the Company's financial condition, the results of operations, and cash flows for the interim period. Results for interim periods are not necessarily indicative of the results to be expected for a full year.
Basis of Presentation and Accounting Estimates	Basis of Presentation and Accounting Estimates: All adjustments consisting of normal recurring accruals that in the opinion of management are necessary for a fair presentation of the financial position and the results of operations for the periods covered by the report have been included. The accompanying unaudited consolidated financial statements and related notes should be read in conjunction with those appearing in the most recent Annual Report previously filed on Form 10-K. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the U.S, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet, and reported amounts of revenues and expenses during the reporting period. 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, the valuation of foreclosed assets and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and business combination elements (Day 1 and Day 2 Valuation).
Recently Issued and Adopted Accounting Pronouncements; Recently Issued Not Yet Effective Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements: As of January 1, 2019, the Company adopted certain accounting standard updates related to accounting for leases (Topic 842 - Leases), primarily Accounting Standards Update ASU 2016-02 and subsequent updates. Among other things, these updates require lessees to recognize a lease liability, measured on a discounted basis, related to the lessee's obligation to make lease payments arising under a lease contract; and a right-of-use asset related to the lessee's right to use, or control the use of, a specified asset for the lease term. The updates did not significantly change lease accounting requirements applicable to lessors and did not significantly impact the Company's consolidated financial statements in relation to contracts whereby the Company acts as a lessor. The Company adopted the updates using a modified-retrospective transition approach and recognized right-of-use lease assets and related lease liabilities totaling $2.3 million each as of January 1, 2019. As of March 31, 2019, right-of-use lease assets and related lease liabilities totaled $2.2 million each. In February 2016, the FASB issued ASU No. 2016-02, Leases . Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee’s obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard. All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. All entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. As the Company elected the transition option provided in ASU No. 2018-11 (see below), the modified retrospective approach was applied on January 1, 2019. Note 1. Presentation of Financial Information, Continued Recently Issued and Adopted Accounting Pronouncements (continued): The Company also elected certain relief options offered in ASU 2016-02 including the package of practical expedients, the option not to separate lease and non-lease components and instead to account for them as a single lease component, and the option not to recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). We elected to apply certain practical adoption expedients provided under the updates whereby we did not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. The Company did not elect the hindsight practical expedient, which allows entities to use hindsight when determining lease term and impairment of right-of-use assets. The Company has several lease agreements, such as branch locations or office space, which are considered operating leases, and therefore, were not previously recognized on the Company’s consolidated balance sheet. The new guidance requires these lease agreements to be recognized on the consolidated balance sheet as a right-of-use asset and a corresponding lease liability. The new guidance did not have a material impact on the consolidated statements of income or the consolidated statements of cash flows. See Note 8 Leases for more information. In July 2018, the FASB issued ASU No. 2018-11, Leases - Targeted Improvements to provide entities with relief from the costs of implementing certain aspects of the new leasing standard, ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02 (January 1, 2019 for the Company). The Company adopted ASU 2018-11 on its required effective date of January 1, 2019 and elected both transition options mentioned above. As of January 1, 2019, the Company adopted ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . The ASU expands the scope of Topic 718, Compensation-Stock Compensation (which previously only included payments to employees), to include share-based payment transactions for acquiring goods and services from non-employees. This required entities to apply the requirements of Topic 718 to non-employee awards, except for specific guidance on inputs to an option pricing model and the attribution of cost (i.e., the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). Additionally, the amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in the grantor’s own operations by issuing share-based payment awards, and clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer, or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. As of January 1, 2019, the Company adopted ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The premium on individual callable debt securities shall be amortized to the earliest call date. This guidance does not apply to securities for which prepayments are estimated on a large number of similar loans where prepayments are probable and reasonably estimable. The adoption of this ASU 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, 2018 as filed with the Securities and Exchange Commission. The following is a summary of recent authoritative pronouncements issued since December 31, 2018 but not yet effective that could impact the accounting, reporting, and/or disclosure of financial information by the Company . Note 1. Presentation of Financial Information, Continued Recently Not Yet Effective Accounting Pronouncements (continued): In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The ASU changed the credit loss model on financial instruments measured at amortized cost, available for sale securities and certain purchased financial instruments. Credit losses on financial instruments measured at amortized cost will be determined using a current expected credit loss model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. Purchased financial assets with more-than-insignificant credit deterioration since origination ("PCD assets" which are currently named "PCI Loans") measured at amortized cost will have an allowance for credit losses established at acquisition as part of the purchase price. Subsequent increases or decreases to the allowance for credit losses on PCD assets will be recognized in the income statement. Interest income should be recognized on PCD assets based on the effective interest rate, determined excluding the discount attributed to credit losses at acquisition. Credit losses relating to available-for-sale debt securities will be recognized through an allowance for credit losses. The amount of the credit loss is limited to the amount by which fair value is below amortized cost of the available-for-sale debt security. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years for the Company and other SEC filers. Early adoption is permitted and if early adopted, all provisions must be adopted in the same period. The amendments should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the period adopted. A prospective approach is required for securities with other than temporary impairment recognized prior to adoption. The Company is continuing its implementation efforts through its company-wide implementation team. The implementation team meets periodically to discuss the latest developments and ensure progress is being made. The team also keeps current on evolving interpretations and industry practices related to ASU 2016-13 via webcasts, publications, conferences, and peer bank meetings. The team continues to evaluate and validate data resources and different loss methodologies. The Company’s preliminary evaluation indicates the provisions of ASU No. 2016-13 are expected to impact the Company’s consolidated financial statements, in particular an increase to the level of the reserve for credit losses. However, the Company continues to evaluate the extent of the potential impact. The guidance of ASU 2016-13 was recently amended by ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, which changed the effective date for non-public companies and clarified that operating lease receivables are not within the scope of the standard.
Reclassifications	Reclassifications: Certain captions and amounts in the 2018 consolidated financial statements were reclassified to conform to the 2019 presentation and these reclassifications had no impact on net income or shareholders' equity as previously reported.
Earnings Per Common Share	Earnings per common share: Basic earnings per common share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance (excluding tax impact). Potential common shares that may be issued by the Company relate solely to outstanding stock options, determined using the treasury stock method, and restricted stock awards, determined by the fair value of the Company's stock on date of grant.
