Do radiant barriers qualify for a tax credit?
As of January 1, 2026, no federal income tax credit is available for radiant barriers or any other insulation products under Section 25C of the tax code.
The Energy Efficient Home Improvement Credit (also known as the 25C credit), which was established by the Inflation Reduction Act of 2022, expired on December 31, 2025.
The IRS has confirmed at irs.gov that the credit "is allowed for qualifying property placed in service on or after Jan. 1, 2023, and before December 31, 2025," and that the credit cannot be claimed for property placed in service after that date.
This termination was further confirmed by the "One Big, Beautiful Bill" signed July 4, 2025. No legislation has extended the credit into 2026 or beyond.
If you installed insulation or air sealing products (including AtticFoil™) and completed the project by December 31, 2025, you may still be eligible to claim the credit on your 2025 tax return (filed in spring 2026). See instructions below.
Eligibility
According to ENERGY STAR's Insulation Tax Credit page, typical bulk insulation products such as batts, rolls, blow-in fibers, rigid boards, expanding spray, and pour-in-place could qualify. Products that air seal (reduce air leaks) — including house wrap — could also qualify if accompanied by a Manufacturer’s Certification Statement.
AtticFoil™ products may have qualified under the house wrap/air sealing category when used as such, with appropriate documentation. Labor costs were not eligible for credit.
If you completed a qualifying project before December 31, 2025 and need to file:
To claim the credit on your 2025 taxes, print a copy of the Manufacturer's Certification Statement and keep it for your records, then complete IRS Form 5695 (Part II) with your tax return. Instructions for Form 5695 are here. Note that for 2025 claims, most product categories (though not insulation/air sealing) require a Qualified Manufacturer Identification Number (QMID) on the form.
Tax Credit: 30% of cost up to $1,200 maximum combined for all improvements in a single year. The cost of labor is not eligible for credit under the incentive. Find more info at the DOE website.
Expired: December 31, 2025
Doesn't AtticFoil™ have to be EnergyStar™ approved to get a rebate?
No, just because a product has an EnergyStar™ label, that does not mean it qualifies for a federal tax rebate. This is a huge misconception that customers ask us about all the time! AtticFoil™ products are eligible for the rebate under the description of Building Envelope Improvements and Bulk Insulation (when used as a house wrap).
How to File: To file for the tax credit, you should print a copy of our Manufacturer’s Certification Certificate and keep it for your records. Then, fill out and submit IRS Form 5695 with your tax return. Instructions for filling out Form 5695 are here.
Are there any other incentives available in 2026?
While the federal 25C credit has ended, some state, local, and utility rebates for insulation may still be available. Use the ENERGY STAR Rebate Finder to search by zip code. For the most accurate and current tax guidance specific to your situation, consult a qualified tax professional.
