Summary of Significant Accounting Policies	Mar. 31, 2021
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Organization In this report, the words “Veritex”, “the Company,” “we,” “us,” and “our” refer to the combined entities of Veritex Holdings, Inc. and its subsidiaries, including Veritex Community Bank. The word “Holdco” refers to Veritex Holdings, Inc. The word “the Bank” refers to Veritex Community Bank. Veritex is a Texas state banking organization, with corporate offices in Dallas, Texas, and currently operates 25 branches and one mortgage office located in the Dallas-Fort Worth metroplex, 12 branches in the Houston metropolitan area and one branch in Louisville, Kentucky. The Bank provides a full range of banking services, including commercial and retail lending and the acceptance of checking and savings deposits, to individual and corporate customers. The Texas Department of Banking (the “TDB”) and the Board of Governors of the Federal Reserve System (the “Federal Reserve”) are the primary regulators of the Company and the Bank, and both regulatory agencies perform periodic examinations to ensure regulatory compliance. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Veritex Holdings, Inc. and its subsidiaries, including Veritex Community Bank. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”), but do not include all of the information and footnotes required for complete financial statements. Intercompany transactions and balances are eliminated in consolidation. In management’s opinion, these unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair statement of the Company’s condensed consolidated financial position at March 31, 2021 and December 31, 2020, condensed consolidated results of operations for the three months ended March 31, 2021 and 2020, condensed consolidated stockholders’ equity for the three months ended March 31, 2021 and 2020 and condensed consolidated cash flows for the three months ended March 31, 2021 and 2020. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end and the results for the interim periods shown herein are not necessarily indicative of results to be expected for the full year due in part to global economic and financial market conditions, interest rates, access to sources of liquidity, market competition and interruptions of business processes. These unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Quarterly Reports on Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K, as filed with the SEC on February 26, 2021. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. These estimates and assumptions may also affect disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Segment Reporting The Company has one reportable segment. All of the Company’s activities are interrelated, and each activity is dependent and assessed based on how each activity of the Company supports the others. For example, lending is dependent upon the ability of the Company to fund itself with deposits and borrowings while managing interest rate and credit risk. Accordingly, all significant operating decisions are based upon an analysis of the Bank as one segment or unit. The Company’s chief operating decision-maker, the Chief Executive Officer, uses the consolidated results to make operating and strategic decisions. Reclassifications Certain items in the Company’s prior year financial statements were reclassified to conform to the current presentation including (i) the reclassification on the condensed consolidated statements of income from net gain on sales of loans and other assets owned for $746 to government guaranteed loan income, net for $439, gain on sale of mortgage loans held for sale for $142 and other income for $165 during the three months ended March 31, 2020, and (ii) the reclassification on the condensed consolidated statements of income from rental income to other income for $551 during the three months ended March 31, 2020. Earnings Per Share (“EPS”) EPS are based upon the weighted average shares outstanding. The table below sets forth the reconciliation between weighted average shares used for calculating basic and diluted EPS for the three months ended March 31, 2021 and 2020: Three Months Ended March 31, 2021 2020 Earnings (numerator) Net income $ 31,787 $ 4,134 Shares (denominator) Weighted average shares outstanding for basic EPS 49,394 50,725 Dilutive effect of employee stock-based awards 604 331 Adjusted weighted average shares outstanding 49,998 51,056 EPS: Basic $ 0.64 $ 0.08 Diluted $ 0.64 $ 0.08 For the three months ended March 31, 2021, there were 75 antidilutive shares excluded from the diluted EPS weighted average shares outstanding, 23 relating to restricted stock units and 52 relating to stock options. For the three months ended March 31, 2020, there were 1,341 antidilutive shares excluded from the diluted EPS weighted average shares outstanding. Recent Accounting Pronouncements ASU 2019-12, "Income Taxes (Topic 740)" ("ASU 2019-12") simplifies the accounting for income taxes by removing certain exceptions and improves the consistent application of GAAP by clarifying and amending other existing guidance. ASU 2019-12 was effective for us on January 1, 2021 and did not have a significant impact on our consolidated financial statements and related disclosures. ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04") amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures. ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs ("ASU 2020-08") clarifies the accounting for the amortization of purchase premiums for callable debt securities with multiple call dates. ASU 2020-08 was effective for us on January 1, 2021 and did not have a significant impact on our consolidated financial statements and related disclosures.

Equity [Abstract]
Share Transactions	Share Transactions On January 28, 2019, the Company's Board of Directors (the “Board”) originally authorized a stock buyback program (the "Stock Buyback Program") pursuant to which the Company could, from time to time, purchase up to $50,000 of its outstanding common stock in the aggregate. The Board authorized increases of $50,000 on September 3, 2019 and $75,000 on December 12, 2019, resulting in an aggregate authorization to purchase up to $175,000 under the Stock Buyback Program. The Board also authorized an extension of the original expiration date of the Stock Buyback Program from December 31, 2019 to December 31, 2021. The shares may be repurchased in the open market or in privately negotiated transactions from time to time, depending upon market conditions and other factors, and in accordance with applicable regulations of the Securities and Exchange Commission. The Stock Buyback Program does not obligate the Company to purchase any share and the program may be terminated or amended by the Board at any time prior to its expiration. During the three months ended March 31, 2021, there were 147,622 shares repurchased through the Stock Buyback Program and held as treasury stock at an average price of $26.83. During the three months ended March 31, 2020, 2,002,211 shares were repurchased through the Stock Buyback Program and held as treasury stock at an average price of $24.78.

Consideration is given to (1) the extent to which the fair value is less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. The number of available for sale debt securities in an unrealized loss position totaled 23 and 11 at March 31, 2021 and December 31, 2020, respectively. Management does not have the intent to sell any of these debt securities and believes that it is more likely than not that the Company will not have to sell any such debt securities before a recovery of cost. The fair value is expected to recover as the debt securities approach their maturity date or repricing date or if market yields for such investments decline. Accordingly, as of March 31, 2021, management believes that the unrealized losses detailed in the previous table are due to noncredit-related factors, including changes in interest rates and other market conditions, and therefore no losses have been recognized in the Company’s condensed consolidated statements of income. The amortized costs and estimated fair values of securities available for sale, by contractual maturity, as of the dates indicated, are shown in the table below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Mortgage-backed securities, collateralized mortgage obligations and asset-backed securities typically are issued with stated principal amounts, and the securities are backed by pools of mortgage loans and other loans that have varying maturities. The terms of mortgage-backed securities, collateralized mortgage obligations and asset-backed securities thus approximates the terms of the underlying mortgages and loans and can vary significantly due to prepayments. Therefore, these securities are not included in the maturity categories below.

As of March 31, 2021 and December 31, 2020, there were no holdings of securities of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of shareholders' equity. There was a blanket floating lien on all debt securities held by the Company to secure FHLB advances as of March 31, 2021 and December 31, 2020.

Receivables [Abstract]
Loans Held for Investment and Allowance for Credit Losses	Loans Held for Investment and Allowance for Credit Losses Loans held for investment in the accompanying condensed consolidated balance sheets are summarized as follows: March 31, 2021 December 31, 2020 Loans held for investment, carried at amortized cost: Real estate: Construction and land $ 723,444 $ 693,030 Farmland 14,751 13,844 1 - 4 family residential 492,609 524,344 Multi-family residential 386,844 424,962 OOCRE 733,310 717,472 NOOCRE 1,970,945 1,904,132 Commercial 1,632,040 1,559,546 MW 599,001 577,594 Consumer 12,431 13,000 6,565,375 6,427,924 Deferred loan fees, net (2,881) (2,468) Allowance for credit losses (104,936) (105,084) Loans held for investment carried at amortized cost, net 6,457,558 6,320,372 Loans held for investment, carried at fair value: PPP loans 407,353 358,042 Total loans held for investment, net $ 6,864,911 $ 6,678,414 Included in the total loans held for investment, net as of March 31, 2021 and December 31, 2020 was an accretable discount related to purchased performing and purchased credit deteriorated (“PCD”) loans acquired within a business combination in the approximate amounts of $13,645 and $15,526, respectively. The discount is being accreted into income on a level-yield basis over the life of the loans. In addition, included in the net loan portfolio as of March 31, 2021 and December 31, 2020 is a discount on retained loans from sale of originated U.S. Small Business Administration (“SBA”) loans of $3,149 and $3,215, respectively. The majority of the Company’s loan portfolio consists of loans to businesses and individuals in the Dallas-Fort Worth metroplex and the Houston metropolitan area. This geographic concentration subjects the loan portfolio to the general economic conditions within these areas. The risks created by this concentration have been considered by management in the determination of the adequacy of the ACL. Management believes the ACL was adequate to cover estimated losses on loans held for investment as of March 31, 2021 and December 31, 2020. PPP loans held for investments, carried at fair value Included in total loans held for investment, net as of March 31, 2021 and December 31, 2020 was $407,353 and $358,042, respectively, of PPP loans, which are carried at fair value. During the three months ended March 31, 2021, the Company recognized PPP fee income of $6,624 which is included in government guaranteed loan income, net on the accompanying condensed consolidated statements of income. During the three months ended March 31, 2021, the Company recognized a net loss of $287 due to the change in the fair value of PPP loans which is included in government guaranteed loan income, net on the accompanying condensed consolidated statements of income and in change in fair value of government guaranteed loans using fair value option on the accompanying condensed consolidated statements of cash flows. These PPP loans were originated through an application to the SBA under the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act and are 100% forgivable if certain criteria are met by the borrowers. As of March 31, 2021, we believe a majority of the Company’s PPP loans will meet such criteria. Allowance for Credit Losses The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. The activity in the ACL related to loans held for investment is as follows: Three Months Ended March 31, 2021 Construction and Land Farmland Residential Multifamily OOCRE NOOCRE Commercial Consumer Total Balance at beginning of year $ 7,768 $ 56 $ 8,148 $ 6,231 $ 9,719 $ 35,237 $ 37,554 $ 371 $ 105,084 Credit loss expense non-PCD loans (949) (9) (1,144) (1,417) (1,615) 4,074 (1,103) (54) (2,217) Credit loss expense PCD loans (14) — (24) — 1,018 192 1,050 (5) 2,217 Charge-offs — — (15) — — — (346) (18) (379) Recoveries — — 3 — — — 226 2 231 Ending Balance $ 6,805 0 $ 47 $ 6,968 $ 4,814 $ 9,122 $ 39,503 $ 37,381 $ 296 $ 104,936 Three Months Ended March 31, 2020 Construction and Land Farmland Residential Multifamily OOCRE NOOCRE Commercial Consumer Total Balance at beginning of year $ 3,822 $ 61 $ 1,378 $ 1,965 $ 1,978 $ 8,139 $ 12,369 $ 122 $ 29,834 Impact of adopting ASC 326 non-PCD loans (707) 4 3,716 628 3,406 5,138 7,025 217 19,427 Impact of adoption ASC 326 PCD loans 645 — 908 — 7,682 2,037 8,335 103 19,710 Credit loss expense non-PCD loans 2,965 (7) 2,488 2,306 918 9,955 10,226 (15) 28,836 Credit loss expense PCD loans 113 — (173) — 2,477 412 126 (15) 2,940 Charge-offs — — — — — — — (68) (68) Recoveries — — 1 — — — 29 274 304 Ending Balance $ 6,838 $ 58 $ 8,318 $ 4,899 $ 16,461 $ 25,681 $ 38,110 $ 618 $ 100,983 The following table presents the amortized cost basis of collateral dependent loans, which are individually evaluated to determine expected credit losses, and the related ACL allocated to these loans as of March 31, 2021 and December 31, 2020, were as follows: March 31, 2021 December 31, 2020 Real Property (1) ACL Allocation Real Property (1) ACL Allocation Real estate: 1 - 4 family residential $ 199 $ 13 $ 199 $ 11 NOOCRE 21,861 2,142 16,080 — Commercial 7,349 4,184 8,666 4,668 Consumer — — 143 50 Total $ 29,409 $ 6,339 $ 25,088 $ 4,729 (1) Loans reported exclude PCD loans that transitioned upon adoption of ASC 326 and accounted for on a pooled basis. Nonaccrual and Past Due Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due in accordance with the terms of the loan agreement . Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Nonaccrual loans aggregated by class of loans, as of March 31, 2021 and December 31, 2020, were as follows: March 31, 2021 December 31, 2020 Nonaccrual Nonaccrual With No ACL Nonaccrual Nonaccrual With No ACL Real estate: 1 - 4 family residential $ 3,282 $ 3,173 $ 3,308 $ 3,199 OOCRE 5,781 4,948 6,266 5,645 NOOCRE 37,131 15,836 40,830 19,213 Commercial 26,177 1,057 29,318 1,015 Consumer 1,223 1,212 1,374 1,220 Total $ 73,594 $ 26,226 $ 81,096 $ 30,292 There were $1,386 and $1,508 of PCD loans that are not accounted for on a pooled basis included in nonaccrual loans at March 31, 2021 and December 31, 2020, respectively. During the three months ended March 31, 2021 and 2020, interest income not recognized on nonaccrual loans was $1,120 and $173, respectively. An age analysis of past due loans, aggregated by class of loans and including past due nonaccrual loans, as of March 31, 2021 and December 31, 2020, is as follows: March 31, 2021 30 to 59 Days 60 to 89 Days 90 Days or Greater Total Past Due Total Current PCD Total Total 90 Days Past Due and Still Accruing (1) Real estate: Construction and land $ 444 $ — $ — $ 444 $ 720,325 $ 2,675 $ 723,444 $ — Farmland — — — — 14,751 — 14,751 — 1 - 4 family residential 2,820 325 5,073 8,218 475,735 8,656 492,609 1,899 Multi-family residential — — — — 386,844 — 386,844 — OOCRE 452 743 451 1,646 693,748 37,916 733,310 — NOOCRE 505 — 10,429 10,934 1,931,382 28,629 1,970,945 7,040 Commercial 6,878 2,953 14,507 24,338 1,589,177 18,525 1,632,040 73 MW — — — — 599,001 — 599,001 — Consumer 115 42 1,215 1,372 10,863 196 12,431 81 Total $ 11,214 $ 4,063 $ 31,675 $ 46,952 $ 6,421,826 $ 96,597 $ 6,565,375 $ 9,093 (1) Loans 90 days past due and still accruing excludes $46,722 of pooled PCD loans as of March 31, 2021 that transitioned upon adoption of ASC 326.

Loans past due 90 days and still accruing were $9,093 and $4,204 as of March 31, 2021 and December 31, 2020, respectively. These loans are also considered well-secured, and are in the process of collection with plans in place for the borrowers to bring the notes fully current or to subsequently be renewed. The Company believes that it will collect all principal and interest due on each of the loans past due 90 days and still accruing. Troubled Debt Restructuring Modifications of terms for the Company’s loans and their inclusion as TDRs are based on individual facts and circumstances. Loan modifications that are included as TDRs may involve a reduction of the stated interest rate of the loan, an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk, or deferral of principal payments, regardless of the period of the modification. The recorded investment in TDRs was $28,769 and $29,157 as of March 31, 2021 and December 31, 2020, respectively. The following tables presents the pre- and post-modification amortized cost of loans modified as TDRs during the three months ended March 31, 2021 and 2020. During the Three Months Ended March 31, 2021 Adjusted Payment Structure Payment Deferrals Total Modifications Number of Loans Commercial $ 240 — $ 240 1 Total $ 240 $ — $ 240 1 During the Three Months Ended March 31, 2020 Adjusted Payment Structure Payment Deferrals Total Modifications Number of Loans Commercial real estate $ — $ 970 $ 970 1 Total $ — $ 970 $ 970 1 There were no loans modified as TDR loans within the previous 12 months and for which there was a payment default during the three months ended March 31, 2021 and 2020. A default for purposes of this disclosure is a TDR loan in which the borrower is 90 days past due or results in the foreclosure and repossession of the applicable collateral. Interest income recorded during the three months ended March 31, 2021 and 2020 on TDR loans and interest income that would have been recorded had the terms of the loans not been modified was minimal. The Company has not committed to lend additional amounts to customers with outstanding loans classified as TDRs as of March 31, 2021 or December 31, 2020. For the three months ended March 31, 2021, the Company had 12 modifications of loans with aggregate principal balances of $4,758 that qualified for temporary suspension of TDR requirements under Section 4013 of the CARES Act, as amended by the Consolidated Appropriations Act, 2021, and related interagency guidance of the federal banking agencies (“Section 4013 of the CARES Act”). For the year ended December 31, 2020, the Company had 754 modifications of loans with aggregate principal balances of $1,126,975 that qualified for temporary suspension of TDR requirements under Section 4013 of the CARES Act. As of March 31, 2021, the Company had $26,088 in loans with remaining deferments. Credit Quality Indicators From a credit risk standpoint, the Company classifies its loans in one of the following categories: (i) pass, (ii) special mention, (iii) substandard or (iv) doubtful. Loans classified as loss are charged-off. Loans not rated special mention, substandard, doubtful or loss are classified as pass loans. The classifications of loans reflect a judgment about the risks of default and loss associated with the loan. The Company reviews the ratings on criticized credits monthly. Ratings are adjusted to reflect the degree of risk and loss that is felt to be inherent in each credit as of each monthly reporting period. All classified credits are evaluated for impairment. If impairment is determined to exist, a specific reserve is established. The Company’s methodology is structured so that specific reserves are increased in accordance with deterioration in credit quality (and a corresponding increase in risk and loss) or decreased in accordance with improvement in credit quality (and a corresponding decrease in risk and loss). Credits rated special mention show clear signs of financial weaknesses or deterioration in credit worthiness, however, such concerns are generally not so pronounced that the Company expects to experience significant loss within the short-term. Such credits typically maintain the ability to perform within standard credit terms and credit exposure is not as prominent as credits with a lower rating. Credits rated substandard are those in which the normal repayment of principal and interest may be, or has been, jeopardized by reason of adverse trends or developments of a financial, managerial, economic or political nature, or important weaknesses which exist in collateral. A protracted workout on these credits is a distinct possibility. Prompt corrective action is therefore required to strengthen the Company’s position, and/or to reduce exposure and to assure that adequate remedial measures are taken by the borrower. Credit exposure becomes more likely in such credits and a serious evaluation of the secondary support to the credit is performed. Credits rated doubtful are those in which full collection of principal appears highly questionable, and in which some degree of loss is anticipated, even though the ultimate amount of loss may not yet be certain and/or other factors exist which could affect collection of debt. Based upon available information, positive action by the Company is required to avert or minimize loss. Credits rated doubtful are generally also placed on non-accrual. Credits classified as PCD are those that, at acquisition date, have experienced a more-than-insignificant deterioration in credit quality since origination. All loans considered to be purchased-credit impaired loans prior to January 1, 2020 were converted to PCD loans upon adoption of ASC 326. The Company elected to maintain pools of loans that were previously accounted for under ASC 310-30 and will continue to account for these pools as a unit of account. Loans are only removed from the existing pools if they are foreclosed, written off, paid off, or sold. The Company considers the guidance in ASC 310-20 when determining whether a modification, extension or renewal of a loan constitutes a current period origination. Generally, current period renewals of credit are re-underwritten at the point of renewal and considered current period originations for purposes of the table below.

Servicing Assets The Company was servicing loans of approximately $261,885 and $211,941 as of March 31, 2021 and 2020, respectively. A summary of the changes in the related servicing assets are as follows: Three Months Ended March 31, 2021 2020 Balance at beginning of period $ 3,363 $ 3,113 Increase from loan sales — 109 Net recoveries 128 — Amortization charged as a reduction to income (89) (232) Balance at end of period $ 3,402 $ 2,990 Fair value of servicing assets is estimated by discounting estimated future cash flows from the servicing assets using discount rates that approximate current market rates over the expected lives of the loans being serviced. A valuation allowance is recorded when the fair value is below the carrying amount of the asset. As of March 31, 2021 and March 31, 2020 there was a valuation allowance of $428 and $536, respectively. The Company may also receive a portion of subsequent interest collections on loans sold that exceed the contractual servicing fees. In that case, the Company records an interest-only strip based on its relative fair market value and the other components of the loans. There was no interest-only strip receivable recorded at March 31, 2021 and December 31, 2020. During the quarter ended March 31, 2021, the Bank sold no SBA loans held for investment. During the quarter ended March 31, 2020, the Bank sold $7,780 of SBA loans held for investment resulting in a gain of $604. The gain on sale of SBA loans is recorded in government guaranteed loan income, net in the accompanying consolidated statements of income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company primarily uses derivatives to manage exposure to market risk, including interest rate risk and credit risk and to assist customers with their risk management objectives. Management will designate certain derivatives as hedging instruments in a qualifying hedge accounting relationship. The Company’s remaining derivatives consist of derivatives held for customer accommodation or other purposes. The fair value of derivative positions outstanding is included in other assets and accounts payable and other liabilities on the accompanying condensed consolidated balance sheets and in the net change in each of these financial statement line items in the accompanying condensed consolidated statements of cash flows. For derivatives not designated as hedging instruments, swap fee income and gains and losses due to changes in fair value are included in other noninterest income and the operating section of the condensed consolidated statement of cash flows. For derivatives designated as hedging instruments, the entire change in the fair value related to the derivative instrument is recognized as a component of other comprehensive income and subsequently reclassified into interest income or interest expense when the forecasted transaction affects income.

The Company uses interest rate swaps, floors, caps and collars to manage overall cash flow changes related to interest rate risk exposure on benchmark interest rate loans. In March 2021, the Company entered into three fixed receive/pay variable interest rate swaps, each with a notional amount of $125,000, to hedge the variability of cash flow payments attributable to changes in interest rates in regards to forecasted of three-month attributable to changes in interest rates in regards to forecasted money market account borrowings from March 2021 through March 2028 and March 2021 through March 2031. In March 2020, the Company entered into an interest rate swap for a notional amount of $500,000 to hedge the variability of cash flow payments attributable to changes in interest rates in regards to forecasted issuances of three-month term debt arrangements every three months from March 2022 through March 2032. These forecasted borrowings can be sourced from a FHLB advance, repurchase agreement, brokered certificate of deposit or some combination. This interest rate swap was terminated on February 24, 2021. The pre-tax gain of $43,900, resulting from the termination of the interest rate swap, will remain in other comprehensive income (loss) and will be accreted over a 10 year period starting in March 2022 unless the forecasted transactions become probable of not occurring. In March 2020, the Company entered into an interest rate swap for a notional amount of $250,000 to hedge the variability of cash flow payments attributable to changes in interest rates in regards to forecasted money market account borrowings from March 2020 through March 2025. In May 2019, the Company entered into a $275,000 notional interest rate floor for commercial loans with a two-year term. The interest rate floor had a purchased floor strike of 2.43%. In February 2020, the Company terminated this interest rate floor. The gain resulting from the termination of the interest rate floor will remain in other comprehensive income (loss) and will be accreted into earnings over the remaining period of the former hedging relationship unless the forecasted transaction becomes probable of not occurring. Interest Rate Swap, Floor, Cap and Collar Agreements Not Designated as Hedging Derivatives In order to accommodate the borrowing needs of certain commercial customers, the Company has entered into interest rate swap or cap agreements with those customers. These interest rate derivative contracts effectively allow the Company’s customers to convert a variable rate loan into a fixed rate loan. In order to offset the exposure and manage interest rate risk, at the time an agreement was entered into with a customer, the Company entered into an interest rate swap or cap with a correspondent bank counterparty with offsetting terms. These derivative instruments are not designated as accounting hedges and changes in the net fair value are recognized in noninterest income or expense. Because the Company acts as an intermediary for its customers, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on the Company’s results of operations. The fair value amounts are included in other assets and other liabilities.

Fair Value Disclosures [Abstract]
Off-Balance Sheet Loan Commitments	Off-Balance Sheet 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 needs of its customers. These financial instruments include commitments to extend credit, MW commitments and standby and commercial letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the condensed consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to a financial instrument for commitments to extend credit, MW commitments and standby and commercial letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The following table sets forth the approximate amounts of these financial instruments as of March 31, 2021 and December 31, 2020: March 31, December 31, 2021 2020 Commitments to extend credit $ 3,075,949 $ 2,743,571 MW commitments 353,884 354,603 Standby and commercial letters of credit 50,243 44,427 Total $ 3,480,076 $ 3,142,601 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 may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Management evaluates each customer’s creditworthiness on a case-by-case basis and substantially all of the Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of future loan funding. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the borrower. MW commitments are unconditionally cancellable and represent the unused capacity on MW facilities the Company has approved. The Company reserves the right to refuse to buy any mortgage loans offered for sale by a customer, for any reason, at the Company’s sole and absolute discretion. Standby and commercial letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby and commercial letters of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company’s policy for obtaining collateral and the nature of such collateral is substantially the same as that involved in making commitments to extend credit. The table below presents the activity in the allowance for unfunded commitment credit losses related to those financial instruments discussed above. This allowance is recorded in accounts payable and other liabilities on the condensed consolidated balance sheets: Three Months Ended March 31, 2021 2020 Beginning balance for allowance for credit losses on unfunded commitments $ 10,747 $ 878 Impact of CECL adoption — 840 Provision for credit losses on unfunded commitments (570) 3,881 Ending balance of allowance for credit losses on unfunded commitments $ 10,177 $ 5,599

Capital Requirements and Restrictions on Retained Earnings	Mar. 31, 2021
Banking and Thrift [Abstract]
Capital Requirements and Restrictions on Retained Earnings	Capital Requirements and Restrictions on Retained Earnings Under applicable U.S. banking laws, there are legal restrictions limiting the amount of dividends the Company can declare. Approval of the regulatory authorities is required if, among other things, the effect of the dividends declared would cause regulatory capital of the Company to fall below specified minimum levels. The Company on a consolidated basis and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements triggers certain mandatory and may lead to additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for Prompt Corrective Action (“PCA”), the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and, if the Bank were not eligible for or did not opt into the Community Bank Leverage Ratio (“CBLR”) framework, certain off-balance sheet items as calculated under regulatory accounting practices. If the Company were not eligible for or did not opt into the CBLR framework, its capital amounts and classification would also be subject to qualitative judgments by the regulators about components of capital, risk weightings of assets, and other factors. Under the Economic Growth, Regulatory Reform, and Consumer Protection Act and implementing regulations of the federal banking agencies, certain banking organizations with less than $10 billion in assets may elect to satisfy a single CBLR of Tier 1 capital to average total consolidated assets in lieu of the generally applicable capital requirements of the capital rules implementing Basel III. We have elected to use the CBLR framework. Accordingly, if we and the Bank continue to meet all requirements under this framework, we and the Bank will not be required to report or calculate risk-based capital, and the Bank will be considered to have met the well-capitalized ratio requirements under PCA regulations. The federal banking agencies have finalized the CBLR minimum at 9% and we and the Bank exceed this standard. The CARES Act temporarily reduced the CBLR to 8% until the earlier of December 31, 2020 or the expiration of the national emergency declaration, and rules issued by the federal banking agencies provide a graduated transition back to the 9% threshold by January 1, 2022. If we were not eligible for or did not opt into the CBLR framework, we would be subject to other quantitative measures established by regulation to ensure capital adequacy. These generally applicable capital requirements require a banking organization that does not operate under the CBLR framework to maintain minimum amounts and ratios (set forth in the table below) of total Tier 1, and common equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets (each as defined in the regulations). Additionally, to be categorized as “well capitalized,” a banking organization that does not operate under the CBLR framework is required to maintain minimum total risk-based common equity Tier 1, Tier 1, and total capital ratios and Tier 1 leverage ratios as set forth in the table below. As of March 31, 2021 and December 31, 2020, the Company’s and the Bank’s capital ratios exceeded those levels necessary to be categorized as “well capitalized” if the Company and the Bank were not operating under the CBLR framework. There are no conditions or events since March 31, 2021 that management believes have changed the Company’s category. In the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provides banking organizations that adopt the current expected credit losses (“CECL”) methodology during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we have elected to utilize the five-year CECL transition. As a result, the effects of CECL on the Company’s and the Bank’s regulatory capital will be delayed through the year 2021, after which the effects will be phased-in over a three-year period from January 1, 2022 through December 31, 2024.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Veritex Holdings, Inc. and its subsidiaries, including Veritex Community Bank. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”), but do not include all of the information and footnotes required for complete financial statements. Intercompany transactions and balances are eliminated in consolidation. In management’s opinion, these unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair statement of the Company’s condensed consolidated financial position at March 31, 2021 and December 31, 2020, condensed consolidated results of operations for the three months ended March 31, 2021 and 2020, condensed consolidated stockholders’ equity for the three months ended March 31, 2021 and 2020 and condensed consolidated cash flows for the three months ended March 31, 2021 and 2020. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end and the results for the interim periods shown herein are not necessarily indicative of results to be expected for the full year due in part to global economic and financial market conditions, interest rates, access to sources of liquidity, market competition and interruptions of business processes. These unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Quarterly Reports on Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K, as filed with the SEC on February 26, 2021.
Segment Reporting	Segment Reporting The Company has one reportable segment. All of the Company’s activities are interrelated, and each activity is dependent and assessed based on how each activity of the Company supports the others. For example, lending is dependent upon the ability of the Company to fund itself with deposits and borrowings while managing interest rate and credit risk. Accordingly, all significant operating decisions are based upon an analysis of the Bank as one segment or unit. The Company’s chief operating decision-maker, the Chief Executive Officer, uses the consolidated results to make operating and strategic decisions.
Earnings Per Share ("EPS")	Earnings Per Share (“EPS”)EPS are based upon the weighted average shares outstanding.
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2019-12, "Income Taxes (Topic 740)" ("ASU 2019-12") simplifies the accounting for income taxes by removing certain exceptions and improves the consistent application of GAAP by clarifying and amending other existing guidance. ASU 2019-12 was effective for us on January 1, 2021 and did not have a significant impact on our consolidated financial statements and related disclosures. ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04") amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures. ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs ("ASU 2020-08") clarifies the accounting for the amortization of purchase premiums for callable debt securities with multiple call dates. ASU 2020-08 was effective for us on January 1, 2021 and did not have a significant impact on our consolidated financial statements and related disclosures.
