Expense Narrative [Text Block] oef_ExpenseNarrativeTextBlock

The tables below illustrate the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in Virtus Funds. More information on these and other discounts is available: (i) from your financial professional or other financial intermediary; (ii) under “Sales Charges” on page 86 of the fund’s prospectus; and (iii) with respect to purchase of shares through specific intermediaries, in Appendix A to the fund’s prospectus, entitled “Intermediary Sales Charge Discounts and Waivers.”

The Virtus Seix Investment Grade Tax-Exempt Bond Fund, a series of Virtus Asset Trust, is the successor of the RidgeWorth Seix Investment Grade Tax-Exempt Bond Fund, a series of RidgeWorth Funds (“Predecessor Fund”), resulting from a reorganization of the Predecessor Fund with and into the fund.

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 51% of the average value of its portfolio.

Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade (BBB-/Baa3 or better) municipal bonds, the income from which is exempt from federal income tax and not subject to the federal alternative minimum tax. The issuers of these securities may be located in any U.S. state, territory or

possession. The fund may invest up to 20% of its assets in securities subject to the U.S. federal income tax. The fund may also invest a portion of its net assets in certain taxable debt instruments. As a result of its investment strategy, the fund’s portfolio turnover rate may be 100% or more.

In selecting investments for purchase and sale, the subadviser tries to manage risk as much as possible. Based on the subadviser’s analysis of municipalities, credit risk, market trends and investment cycles, the subadviser attempts to invest more of the fund’s assets in undervalued municipal securities and less in overvalued municipal securities taking into consideration maturity, sector, credit, state and supply and demand levels.

The subadviser also attempts to identify and invest in municipal issuers with improving credit and avoid those with deteriorating credit. The subadviser anticipates that the fund’s effective maturity will range from 4 to 10 years but there is no limit on the maturities of individual securities in which the fund may invest. The fund invests in securities rated investment grade by at least one nationally recognized statistical rating organization or unrated securities that the subadviser believes are of comparable quality. The subadviser may retain securities if the rating of the security falls below investment grade and the subadviser deems retention of the security to be in the best interests of the fund.

In addition, to implement its investment strategy, the fund may buy or sell derivative instruments (such as treasury futures) to use as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks.

Risk [Text Block] oef_RiskTextBlock

Principal Risks

The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or municipalities in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below.

Virtus Seix Investment Grade Tax-Exempt Bond Fund | Market Volatility Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Virtus Seix Investment Grade Tax-Exempt Bond Fund | Derivatives Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.
Virtus Seix Investment Grade Tax-Exempt Bond Fund | Income Risk  
Risk/Return: oef_RiskReturnAbstract

Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Prepayment/Call Risk: Issuers may prepay or call their fixed rate obligations when interest rates fall, forcing the fund to reinvest in obligations with lower interest rates and the fund may not benefit fully from the increase in value that other fixed income investments experience when interest rates decline.
Virtus Seix Investment Grade Tax-Exempt Bond Fund | Redemption Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s NAV and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.

The fund’s investment adviser has contractually agreed to limit the fund’s total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, expenses incurred in connection with any merger or reorganization, unusual or infrequently occurring expenses (such as litigation), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 0.67% for Class A Shares and 0.50% for Class I Shares through April 30, 2027. Prior to April 30, 2027, only the fund’s Board may modify or terminate the expense limitation agreement. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, and any in effect at the time of recapture, after repayment is taken into account.
