The purpose of this legislation, known as the Municipal Investment and Neighborhood Transformation Act or the MINT Act, is to change how certain state and local bonds are treated for tax purposes. Specifically, it aims to restore the tax-exempt status of bonds that are guaranteed by a Federal home loan bank, which means these bonds will not be considered federally guaranteed when determining their tax-exempt status. Key provisions of the MINT Act include amending the Internal Revenue Code to remove specific time limitations on when these bonds can be issued to qualify for tax-exempt status.
