SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying unaudited consolidated financial statements of Investar Holding Corporation (the “Company”) have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include information or footnotes necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with GAAP. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial statements have been included. The results of operations for the three month period ended March 31, 2015 are not necessarily indicative of the results that may be expected for the entire fiscal year. These statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2014, including the notes thereto, which were included as part of the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 31, 2015.
	Nature of Operations
	Investar Holding Corporation, headquartered in Baton Rouge, Louisiana, provides full banking services, excluding trust services, through its wholly-owned banking subsidiary, Investar Bank (the “Bank”), a Louisiana-chartered bank. The Company’s primary market is South Louisiana. The Company currently operates 11 full service banking offices located throughout its market and had 177 employees at March 31, 2015.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could be material. Material estimates that are susceptible to a significant change in the near term are the allowance for loan losses, the fair value of financial instruments and the determination of other-than-temporary impairments of securities.
	Reclassifications
	Certain reclassifications have been made to the 2014 financial statements to be consistent with the 2015 presentation.
	Concentrations of Credit Risk
	The Company’s loan portfolio consists of the various types of loans described in Note 4, Loans. Real estate or other assets secure most loans. The majority of loans has been made to individuals and businesses in the Company’s market of South Louisiana. Customers are dependent on the condition of the local economy for their livelihoods and servicing their loan obligations. The Company does not have any significant concentrations in any one industry or individual customer.
	Recent Accounting Pronouncements
	FASB ASC Topic 835-30 “Interest-Imputation of Interest” Update No. 2015-03. The Financial Accounting Standards Board (the “FASB”) issued Update No. 2015-03 in April 2015 as part of its initiative to reduce complexity in the accounting standards. To simplify presentation of debt issuance costs, the amendments in this Update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. For public entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position.
	FASB ASC Topic 810 “Consolidation” Update No. 2015-02.  The FASB issued Update No. 2015-02 in February 2015 to respond to stakeholders’ concerns about the current accounting for consolidation of certain legal entities. The amendments in the update change the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities and are effective for public entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015.  The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position.
	FASB ASC Topic 225-20 “Income Statement – Extraordinary and Unusual Items” Update No. 2015-01. The FASB issued Update No. 2015-01 in January 2015 as part of its initiative to reduce complexity in accounting standards. This update eliminates from GAAP the concept of extraordinary items. The amendments in the update are effective for the annual period ending after December 15, 2015.  Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position.

The unrealized losses in the Company’s investment portfolio, caused by interest rate increases, are not credit issues, and the Company does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. The Company does not consider these securities to be other-than-temporarily impaired at March 31, 2015 or December 31, 2014.
The weighted average tax equivalent yield, amortized cost and approximate fair value of investment securities, by contractual maturity (including mortgage-backed securities), are shown below as of the dates presented. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties (dollars in thousands).

	Total loans at March 31, 2015 include approximately $42.8 million of loans acquired in the FCB and SLBB acquisitions that were recorded at fair value as of their respective acquisition dates. Included in the acquired loan balances at March 31, 2015 were approximately $0.6 million in loans 30-59 days past due and $1.0 million in nonaccrual loans. There were no acquired loans 60-89 or 90 or more days past due at March 31, 2015.
	Total loans at December 31, 2014 include approximately $45.0 million of loans acquired in the FCB and SLBB acquisitions that were recorded at fair value as of their respective acquisition dates. Included in the acquired loan balances at December 31, 2014 were approximately $0.3 million in loans 30-59 days past due, $14,000 in loans 60-89 days past due, and $1.1 million in nonaccrual loans. There were no acquired loans 90 or more days past due at December 31, 2014.
	Credit Quality Indicators
	Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The following definitions are utilized for risk ratings, which are consistent with the definitions used in supervisory guidance:
	Pass – Loans not meeting the criteria below are considered pass. These loans have the highest credit characteristics and financial strength. Borrowers possess characteristics that are highly profitable, with low to negligible leverage and demonstrate significant net worth and liquidity.
	Special Mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date.
	Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
	Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
	Loss – Loans classified as loss are considered uncollectible and of such little value that their continuance as recorded assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off these assets.
	The following table presents a breakdown of the Company’s loan portfolio by credit quality indicators as of the dates presented (dollars in thousands):

The Company had no loans that were classified as doubtful or loss as of March 31, 2015 or December 31, 2014.
Loan participations and whole loans sold to and serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balances of these loans were approximately $285.9 million and $189.6 million as of March 31, 2015 and December 31, 2014, respectively.
In the ordinary course of business, the Company makes loans to its executive officers, principal stockholders, directors and to companies in which these individuals are principal owners. Loans outstanding to such borrowers (including companies in which they are principal owners) amounted to approximately $24.9 million and $22.8 million as of March 31, 2015 and December 31, 2014, respectively. These loans are all current and performing according to the original terms. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company or the Bank and did not involve more than normal risk of collectability or present other unfavorable features.
The aggregate amount of loans to such related parties is as follows as of the dates presented (dollars in thousands):
	31-Mar-15			31-Dec-14

	Impaired Loans
	The Company considers a loan to be impaired when, based on current information and events, the Company determines that it will not be able to collect all amounts due according to the loan agreement, including scheduled interest payments. Determination of impairment is treated the same across all classes of loans. When the Company identifies a loan as impaired, it measures the impairment based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole (remaining) source of repayment for the loans is the operation or liquidation of the collateral. In these cases when foreclosure is probable, the Company uses the current fair value of the collateral, less selling costs, instead of discounted cash flows. If the Company determines that the value of the impaired loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), the Company recognizes impairment through an allowance estimate or a charge-off to the allowance.
	When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan is not in doubt and the loan is on nonaccrual, contractual interest is credited to interest income when received, under the cash basis method.
The following tables include the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable, as of the dates indicated. The Company determined the specific allowance based on the present values of expected future cash flows, discounted at the loan’s effective interest rate, except when the remaining source of repayment for the loan is the operation or liquidation of the collateral. In those cases, the current fair value of the collateral, less selling cost, was used to determine the specific allowance recorded (dollars in thousands).

In situations where, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession for other than an insignificant period of time to the borrower that the Company would not otherwise consider, the related loan is classified as a troubled debt restructuring (“TDR”). The Company strives to identify borrowers in financial difficulty early and work with them to modify their loans to more affordable terms before such loans reach nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where the Company grants the borrower new terms that provide for a reduction of either interest or principal, the Company measures any impairment on the restructuring as previously noted for impaired loans.
Loans classified as TDRs, consisting of ten credits, totaled approximately $1.5 million at March 31, 2015 compared to seven credits totaling approximately $0.6 million at December 31, 2014. Nine of the ten TDRs were acquired from FCB. Nine of the ten credits were considered TDRs due to modification of terms through adjustments to maturity and one was considered a TDR due to modification of terms through principal payment forbearance, paying interest only for a specified period of time. Nine of the ten credits are currently performing in accordance with their modified terms. The remaining TDR was in default of its modified terms as of the date these financial statements were issued. The Company individually evaluates each TDR for allowance purposes, primarily based on collateral value, and excludes these loans from the loan population that is evaluated by applying qualitative factors.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	NOTE 6. DERIVATIVE FINANCIAL INSTRUMENTS
	The Bank currently holds forward starting interest rate swap contracts to manage exposure against the variability in the expected future cash flows (future interest payments) attributable to changes in the 1-month LIBOR associated with the forecasted issuances of 1-month fixed rate debt arising from a rollover strategy. An interest rate swap is an agreement whereby one party agrees to pay a fixed rate of interest on a notional principal amount in exchange for receiving a floating rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged. The maximum length of time over which the Bank is currently hedging its exposure to the variability in future cash flows for forecasted transactions is five years. The total notional amount of the derivative contracts is $20.0 million.
	For the three months ended March 31, 2015, a loss of $0.2 million has been recognized in other comprehensive income in the accompanying consolidated statement of other comprehensive income for the change in fair value of the interest rate swap. The swap contract had a negative fair value of $0.7 million as of March 31, 2015 and has been recorded in other liabilities in the accompanying consolidated balance sheets. The loss of $0.4 million included in accumulated other comprehensive income would be reclassified to current earnings if the hedge transactions become probable of not occurring. The Bank expects the hedges to remain fully effective during the remaining term of the swap contracts.

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	NOTE 7. FAIR VALUES OF FINANCIAL INSTRUMENTS
	In accordance with FASB ASC Topic 820, Fair Value Measurement and Disclosure (“ASC 820”), disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, is required. 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 under current market conditions. 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, and the fair value estimates may not be realized in an immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.
	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 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.
	Fair Value Hierarchy
	In accordance with ASC 820, the Company groups its financial assets and financial liabilities 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 following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:
	Cash and Due from Banks – For these short-term instruments, fair value is the carrying value. Cash and due from banks is classified in level 1 of the fair value hierarchy.
	Federal Funds Sold/Purchased and Securities Sold under Repurchase Agreements – The fair value is the carrying value. The Company classifies these assets in level 1 of the fair value hierarchy.
	Investment Securities and Other Equity Securities – Where quoted prices are available in an active market, the Company classifies the securities within level 1 of the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include highly liquid government bonds and exchange-traded equities.
	If quoted market prices are not available, the Company estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, and credit spreads. Examples of such instruments, which would generally be classified within level 2 of the valuation hierarchy, include Government Sponsored Enterprise obligations, corporate bonds and other securities. Mortgage-backed securities are included in level 2 if observable inputs are available. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in level 3. Equity securities are valued based on market quoted prices and are classified in level 1 as they are actively traded.
	Loans – For variable-rate loans that re-price frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (for example, one-to-four family residential), credit card loans, and other consumer loans are based on quoted market prices of similar instruments sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. Fair values for other loans (for example, commercial real estate and investment property mortgage loans, commercial and industrial loans) are estimated using discounted cash flow analyses, using market interest rates for comparable loans. Fair values for nonperforming loans, which are loans for which the accrual of interest has stopped or loans that are contractually 90 past due on which interest continues to accrue, are estimated using discounted cash flow analyses or underlying collateral values, where applicable. The Company classifies loans in level 3 of the fair value hierarchy.
	Loans held for sale are measured using quoted market prices when available. If quoted market prices are not available, comparable market values or discounted cash flow analyses may be utilized. The Company classifies these assets in level 3 of the fair value hierarchy.
	Real Estate Owned – The fair values are estimated based on recent appraisal values of the property less estimated costs to sell the property, as real estate owned is valued at the lower of cost or fair value of the property, less estimated costs to sell. Certain inputs used in appraisals are not always observable, and therefore real estate owned may be classified in level 3 within the fair value hierarchy. When inputs are observable, these assets are classified in level 2 of the fair value hierarchy.
	Accrued Interest – The carrying amounts of accrued interest approximate fair value and are classified in level 1 of the fair value hierarchy.
	Deposit Liabilities – The fair values disclosed for noninterest-bearing demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). These noninterest-bearing deposits are classified in level 2 of the fair value hierarchy. The carrying amounts of variable-rate (for example interest-bearing checking, savings, and money market accounts), fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates on comparable instruments to a schedule of aggregated expected monthly maturities on time deposits. All interest-bearing deposits are classified in level 3 of the fair value hierarchy.
	Short-Term Borrowings – The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings maturing within 90 days approximate their fair values.  The Company classifies these borrowings in level 2 of the fair value hierarchy.
	Long-Term Borrowings – The fair values of long-term borrowings are estimated using discounted cash flows analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The fair value of the Company’s long-term debt is therefore classified in level 3 in the fair value hierarchy.
	Commitments – The fair value of commitments to extend credit was not significant.
	Derivative Instruments – The fair value for interest rate swap agreements are based upon the amounts required to settle the contracts. These derivative instruments are classified in level 2 of the fair value hierarchy.

	The Company is a party to financial instruments with off-balance-sheet risk entered into in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, which are not included in the accompanying financial statements.
	Commitments to extend credit are agreements to lend money with fixed expiration dates or termination clauses. The Company applies the same credit standards used in the lending process when extending these commitments, and periodically reassesses the customer’s creditworthiness through ongoing credit reviews. Since some commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Collateral is obtained based on the Company’s assessment of the transaction. Essentially all letters of credit issued have expiration dates within one year. At March 31, 2015 and December 31, 2014, the Company’s commitments to extend credit totaled approximately $121.8 million and $91.5 million, respectively.
	The Company is required to maintain average reserves at the Federal Reserve Bank. There were approximately $10.5 million and $12.9 million in required reserves at March 31, 2015 and December 31, 2014, respectively.

Recent Accounting Pronouncements	Recent Accounting Pronouncements
	FASB ASC Topic 835-30 “Interest-Imputation of Interest” Update No. 2015-03. The Financial Accounting Standards Board (the “FASB”) issued Update No. 2015-03 in April 2015 as part of its initiative to reduce complexity in the accounting standards. To simplify presentation of debt issuance costs, the amendments in this Update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. For public entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position.
	FASB ASC Topic 810 “Consolidation” Update No. 2015-02.  The FASB issued Update No. 2015-02 in February 2015 to respond to stakeholders’ concerns about the current accounting for consolidation of certain legal entities. The amendments in the update change the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities and are effective for public entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015.  The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position.
	FASB ASC Topic 225-20 “Income Statement – Extraordinary and Unusual Items” Update No. 2015-01. The FASB issued Update No. 2015-01 in January 2015 as part of its initiative to reduce complexity in accounting standards. This update eliminates from GAAP the concept of extraordinary items. The amendments in the update are effective for the annual period ending after December 15, 2015.  Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position.

Schedule of Aging Analysis of Loans	The following tables include the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable, as of the dates indicated. The Company determined the specific allowance based on the present values of expected future cash flows, discounted at the loan’s effective interest rate, except when the remaining source of repayment for the loan is the operation or liquidation of the collateral. In those cases, the current fair value of the collateral, less selling cost, was used to determine the specific allowance recorded (dollars in thousands).
