New Requirements for Energy Efficiency Credits Take Effect in 2025

The IRS offers a variety of tax credits to people who invest in home improvements that significantly reduce energy usage. These nonrefundable credits may total up to $3,200 for a particular year. A maximum credit of $2,000 is available for water heaters, heat pumps, boilers or biomass stoves that meet specific design and efficiency requirements. Meanwhile, qualifying homeowners may claim up to $1,200 in credits for other energy improvements like installing highly efficient exterior doors, windows or skylights.

Beginning January 1, 2025, only officially certified products will be eligible for these tax credits. The products must come from an IRS-approved manufacturer, and the manufacturer must label each product with a unique product identification number (PIN). Save these labels, because in order to claim a home efficiency credit, you will need to include the PIN of each eligible product on your 2025 tax return. If a contractor or retailer cannot show you a clearly displayed PIN on a particular product, then the product likely will not qualify for tax credits for energy efficiency.
