It is important for the homeowner to download and retain the manufacturing certification statement for the installation year as well as the purchase receipt for each eligible window and door, as it may be requested by the Internal Revenue Service (IRS).

This tax credit helps to provide opportunities for homeowners to make homes and buildings more energy efficient to help reduce energy costs as part of the transition to cleaner energy sources.

This new energy efficienct tax credit took effect on Jan. 1, 2023, and will not expire until Dec. 31, 2032. The tax credit amount is mostly limited to 30% of the project cost. The previous lifetime cap of $500 was changed to an annual cap of either $1,100 to $2,000, depending on the improvements. Homeowners can now claim credit for more projects, especially if they are completed over multiple years.

These Energy Efficiency Home Improvement credits will be applicable on several products to help homeowners maximize their savings, and all now must meet ENERGY STAR Most Efficient criteria.
