Solid American Hardwood Tax Credit Act

This bill adds a new tax credit for homeowners who install qualifying U.S.-grown hardwood products in their primary residence. It expands the existing energy efficient home improvement credit to cover "natural carbon sink expenditures," defined as flooring, paneling, cabinetry, or windows made from deciduous trees grown and processed in the U.S. The credit applies to products installed in a dwelling owned and used as the taxpayer’s principal residence, with the installation expected to last at least five years. The bill also extends the credit’s expiration date from 2032 to 2035.
