To amend the Internal Revenue Code of 1986 to repeal the production tax credit and the investment tax credit.

HR 6644 repeals two key tax credits for renewable energy producers under the Internal Revenue Code: the production tax credit (Section 45) and the investment tax credit (Section 48). This bill directly affects companies generating electricity from wind, solar, and other renewable sources that previously relied on these tax breaks. The repeal takes effect for electricity produced and sold after December 31, 2021, ending these specific tax incentives for renewable energy projects. The change removes these credits from the tax code without creating new provisions.
