Solid American Hardwood Tax Credit Act

This bill adds a tax credit for homeowners who install U.S.-grown hardwood flooring, paneling, cabinetry, or window frames in their principal residence. It defines "natural carbon sink expenditures" to include these specific U.S. hardwood products, which absorb carbon dioxide. The credit applies to purchases made after the bill's enactment, extending the existing energy-efficient home improvement credit through 2035. It directly affects homeowners purchasing qualifying U.S. hardwood materials for home renovations.
