> The Alternative Fuel Refueling Property Credit expired at the end of 2021, but the Inflation Reduction Act gave it life again by extending its application through 2032. For homeowners, the credit is worth 30% of the costs of "qualified alternative fuel vehicle refueling property" installed in the home, up to $1,000.
