This bill significantly modifies the existing energy efficient home improvement credit under Section 25C of the Internal Revenue Code. It introduces a new component allowing taxpayers to claim a credit for **natural carbon sink expenditures** made on their principal residences. These expenditures specifically cover products like flooring, paneling, cabinetry, and window frames, provided they are comprised of **deciduous trees grown and processed in the United States** and are expected to remain in use for at least five years. The bill also extends the availability of this modified credit until 2035. In addition to expanding home improvement credits, the legislation addresses carbon oxide sequestration by amending Section 45Q of the Internal Revenue Code. It mandates the **termination of the increased credit for carbon capture equipment** if the construction of such equipment begins after the bill's enactment date. This provision aims to adjust incentives related to industrial carbon sequestration efforts.
