State Tax Freedom Act This bill removes a prohibition on states and territories using COVID-19 relief funding under the American Rescue Plan Act of 2021 to offset a reduction in revenue resulting from a reduction in taxes or a delay in the imposition of a tax or tax increase. Additionally, the bill requires the Department of the Treasury to refund the state, territory, or tribal government any money that was repaid to the federal government since enactment of the American Rescue Plan Act of 2021 due to the state cutting taxes.
