Door Replacement Tax Credits: What Qualifies

Updated October 2026.

Door replacements are often viewed as an aesthetic upgrade, yet they also play a key role in home efficiency. A well-insulated front door reduces drafts, lowers heating costs, and improves overall comfort. From 2023 through 2025, homeowners could also claim a federal tax credit for a qualifying energy-efficient exterior door. That credit has ended: it does not apply to doors placed in service after December 31, 2025. Here is what changed, how the credit worked, and what can still lower the cost of an efficient door in 2026.

Is There a Tax Credit for Exterior Doors in 2026?

No. The IRS instructions for Form 5695 state that you “can’t claim energy efficient home improvement credits for expenditures or property placed in service after December 31, 2025.” Placed in service means installed, so the date that matters is when the door went in, not when it was ordered or paid for. A front door installed in 2026 does not qualify for the federal credit.

If your new door was installed in 2025, you may still be able to claim it on your 2025 return. The rest of this article explains how the credit worked for those doors.

How the Door Tax Credit Worked (2023–2025)

According to the IRS, the Energy Efficient Home Improvement Credit covered qualifying improvements placed in service from January 1, 2023 through December 31, 2025. For exterior doors:

• The credit was 30 percent of the cost of the door.
• It was capped at $250 per door and $500 a year for all exterior doors, within the credit’s overall $1,200 annual limit.
• The door had to meet applicable ENERGY STAR requirements.
• It had to be installed in your main home in the United States, the home you live in most of the year.
• Installation costs for doors could not be counted toward the credit.

Claiming a Door Installed in 2025

Doors placed in service in 2025 are claimed on Form 5695, filed with your 2025 federal income tax return. For doors installed in 2025, the IRS also requires the manufacturer’s qualified manufacturer identification number (QMID) for the door to be reported on the form. Keep your receipt and any manufacturer certification with your records. If you are unsure whether your door qualifies, ask a tax professional.

State and Utility Rebates

State and utility programs run separately from the federal credit, so some may still offer rebates for efficient doors. The Database of State Incentives for Renewables and Efficiency lets you search incentives by ZIP code. Programs change often, so read each program’s product requirements before you buy.

What Still Saves Money: An Efficient Door

Without a federal credit, the lasting return on an efficient front door is on your energy bill and in your comfort. When you compare doors, look for:

• U-factor: how much heat passes through the door. Lower is better.
• Solar heat gain coefficient (SHGC): how much of the sun’s heat comes through the glass. Lower is better in hot, sunny climates.
• A strong insulated core, and high-performance glass if the door has glass.
• Tight seals and a careful installation, because gaps waste what the door saves.

Knockety publishes these numbers. Depending on the model and glass, our doors have a U-factor of 0.24 to 0.42 and an SHGC of 0.09 to 0.33. They are built with multi-layered cores that resist warping and with double-pane glass.
