How Insulation Rebates Work in 2026
There are three ways to get money back on insulation in 2026: the federal 25C Energy Efficient Home Improvement Credit, IRA-funded HEAR rebates administered by your state, and utility company rebates. These programs can be stacked on the same project for maximum savings.
The 25C tax credit is available to all homeowners regardless of income — 30% of insulation material and installation costs, up to $1,200 per tax year. The HEAR rebate is for households below 150% of Area Median Income and is administered by each state separately through IRA funding.
✓ Stack All Three — No Double-Dipping Rule
Federal 25C + State HEAR + Utility rebates can all be combined on the same insulation project as long as total incentives don't exceed project cost. An income-qualified homeowner in Michigan could receive: HEAR $1,600 + DTE $400 + 25C $1,200 = $3,200 total back on one project.
⚠ HEAR Requires State-Enrolled Contractors
HEAR rebates are processed through your state's program administrator — not through your tax return. You must use a registered contractor and get pre-approval before the project starts in most states. Tax credits are claimed on Form 5695 at tax time.

FAQ — Insulation Rebates
Do I need an energy audit before getting insulation rebates?
Most HEAR programs require a certified energy audit before rebate approval. The audit identifies the best insulation opportunities and creates a baseline for calculating efficiency improvements. Some states cover audit costs through weatherization programs — ask your state's program administrator.
Can renters get insulation rebates?
HEAR rebates are generally available to both homeowners and renters of single-family homes, with landlord permission. Multifamily properties may have different rules. Renters cannot claim the 25C federal tax credit (which requires homeownership).
What form do I use for the 25C insulation tax credit?
Claim the 25C credit on IRS Form 5695 (Residential Energy Credits). File with your annual federal tax return. Keep receipts and manufacturer certification statements. The credit is nonrefundable — it reduces your tax liability but won't generate a refund beyond what you owe.
Is spray foam insulation eligible for the 25C credit?
Yes — spray foam insulation qualifies for the 25C credit if it meets IECC standards for your climate zone. Both open-cell and closed-cell spray foam are eligible. However, air sealing performed as part of spray foam installation may be counted separately toward the combined $1,200 insulation + air sealing cap.
