What Homeowners Need to Know About the 25C Door Tax Credit
- Program dates: The 25C tax credit covered energy efficient exterior doors purchased and installed between January 1, 2023 and December 31, 2025. That window is now closed.
- Credit amounts: Eligible homeowners could claim 30% of the door’s product cost, up to $250 per door. The cap for all door credits in a single tax year was $500.
- 2025 filers still qualify: If your door was installed by December 31, 2025, you can still claim the credit on your 2025 federal tax return. The deadline to file is not the same as the installation deadline.
- ENERGY STAR Most Efficient required: Not all ENERGY STAR-labeled doors qualified. The door needed to meet the stricter ENERGY STAR Most Efficient designation to be eligible for the credit.
- How to file: Claim your 2025 door credit using IRS Form 5695, Residential Energy Credits. You will need the Qualified Manufacturer ID Number, or QMID, from your contractor to complete the form.
- CWE provides documentation: Coastal Windows & Exteriors can supply the manufacturer documentation and QMID needed to file your 2025 credit claim. Just reach out to our team and we’ll get it to you.
