2025 Guide: How to Claim the U.S. Energy Efficient Home Improvement Tax Credit

As environmental awareness grows, the U.S. government is encouraging homeowners to make energy-efficient upgrades to their existing homes. Starting in 2025, the IRS has introduced new requirements for the Energy Efficient Home Improvement Tax Credit, and this article explains the eligibility criteria, qualified improvements, and key things to keep in mind when claiming the credit.

What Is the Energy Efficient Home Improvement Tax Credit?

This federal tax credit is designed to help homeowners reduce energy consumption and carbon emissions by incentivizing energy-efficient upgrades—such as installing new HVAC systems, windows, insulation, or electric panel upgrades.

Beginning in 2025, many eligible products will require a Qualified Manufacturer (QM) Code, which helps the IRS confirm that the product meets federal efficiency standards.

Eligibility by Improvement Type

The type of improvement determines whether your property qualifies. Here’s a breakdown:

Exterior Doors, Windows, Skylights, Insulation, and Air Sealing Materials/Systems

• The home must be located in the U.S.

• You must own and use the home as your primary residence

• Second homes and rental properties are not eligible

• Only existing homes qualify (not new construction)

Central Air Conditioners, Heat Pumps, Water Heaters, Biomass Stoves, and Electrical System Upgrades

• Upgrading your home’s HVAC system or water heater

• Replacing windows, doors, or insulation with energy-efficient models
