Performance Narrative [Text Block]
The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Rochester AMT-Free Municipal Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund’s and the Fund’s performance to that of a broad measure of market performance and an additional index with characteristics relevant to the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C and Class Y shares of the predecessor fund. Class A, Class C and Class Y shares of the predecessor fund were reorganized into Class A, Class C and Class Y shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C and Class Y shares’ returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund’s applicable sales charge.
Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.
All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.
Updated performance information is available on the Fund’s website at www.invesco.com/us.

Bar Chart and Performance Table [Heading] Performance Information
Performance Narrative [Text Block]
The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Rochester Limited Term New York Municipal Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund’s and the Fund’s performance to that of a broad measure of market performance and one or more additional indices with characteristics relevant to the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C and Class Y shares of the predecessor fund. Class A, Class C and Class Y shares of the predecessor fund were reorganized into Class A, Class C and Class Y shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C and Class Y shares’ returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund’s applicable sales charge.
Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.
All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.
Updated performance information is available on the Fund’s website at www.invesco.com/us.
