Example

The 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. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The one-year example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the expense limitation agreement by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - BNY Mellon AMT-Free Municipal Bond Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	518	664	822	1,281
Class C	248	465	805	1,766
Class I Shares	46	144	252	567
Class Y	44	138	241	542
Class Z	46	144	252	567

Expense Example No Redemption - BNY Mellon AMT-Free Municipal Bond Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	518	664	822	1,281
Class C	148	465	805	1,766
Class I Shares	46	144	252	567
Class Y	44	138	241	542
Class Z	46	144	252	567

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover 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 17.22% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal bonds that provide income exempt from federal personal income tax and the federal alternative minimum tax. Municipal bonds are debt securities or other obligations issued by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, or multistate agencies and authorities.

The fund invests at least 65% of its net assets in municipal bonds rated, at the time of purchase, A or higher or the unrated equivalent as determined by Insight North America LLC, the fund's sub-adviser. The fund may invest up to 35% of its net assets in municipal bonds rated, at the time of purchase, below A, including bonds rated below investment grade ("high yield" or "junk" bonds), or the unrated equivalent as determined by the fund's sub-adviser.

The dollar-weighted average maturity of the fund's portfolio normally exceeds ten years, but the fund may invest without regard to maturity. A bond's maturity is the length of time until the principal must be fully repaid with interest. Dollar-weighted average maturity is an average of the stated maturities of the bonds held by the fund, based on their dollar-weighted proportions in the fund.

The fund's sub-adviser focuses on identifying undervalued sectors and securities. To select municipal bonds for the fund, the sub-adviser uses fundamental credit analysis to estimate the relative value and attractiveness of various sectors and securities and actively trades among various sectors and securities based on their apparent relative values. The fund seeks to invest in several different sectors, and does not seek to overweight any particular sector but may do so depending on each sector's relative value at a given time.

A rigorous sell discipline is employed to continuously evaluate all fund holdings. Current holdings may become sell candidates if creditworthiness is deteriorating, if bonds with better risk and return characteristics become available, or if the holding no longer meets the sub-adviser's strategic or portfolio construction objectives.

Although the fund seeks to provide income exempt from federal income tax and the federal alternative minimum tax, income from some of the fund's holdings may be subject to these taxes.

Principal Risks

Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Class Z shares from year to year. Sales charges, if any, are not reflected in the bar chart and, if those charges were included, returns would have been less than those shown. The table compares the average annual total returns of the fund's shares to those of a broad measure of market performance. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. More recent performance information may be available at www.im.bnymellon.com.

Year-by-Year Total Returns as of 12/31 each year (%) Class Z

Best Quarter
Q1, 2014: 3.90%

Worst Quarter
Q1, 2022: -6.04%

The year to date total return of the fund's Class Z shares as of September 30, 2023 was -0.75%.

Average Annual Total Returns (as of 12/31/22)

After-tax performance is shown only for Class Z shares. After-tax performance of the fund's other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through U.S. tax-deferred arrangements such as 401(k) plans or individual retirement accounts. Returns after taxes on distributions and sale of fund shares may be higher than returns before taxes or returns after taxes on distributions due to an assumed tax benefit from losses on a sale of the fund's shares at the end of the period.

For the fund's Class Y shares, periods prior to the inception date reflect the performance of the fund's Class Z shares. Such performance figures have not been adjusted to reflect applicable class fees and expenses of Class Y shares. Each share class is invested in the same portfolio of securities, and the annual returns would have differed only to the extent that the classes have different expenses.
