Insulation upgrades don’t just make your home more comfortable—they can also put money back in your pocket. Thanks to expanded federal and utility rebate programs, 2025 is one of the best years to take advantage of insulation savings. But there’s urgency: the 25C Energy Efficient Home Improvement Tax Credit expires on December 31, 2025.
Here are 7 steps to maximize your insulation tax credits and rebates in 2025:
1. Understand What’s Available
The federal Energy Efficient Home Improvement Credit (25C) provides up to 30% back on qualifying insulation and air sealing costs, with an annual maximum of $1,200.
➡️ Learn more from the IRS website.
Local utilities also help homeowners save. For example, CenterPoint Energy Indiana offers rebates for qualifying customers:
- $450 attic insulation rebate (confirmed)
- Potential duct sealing rebate (amounts vary by program; sometimes up to $350)
When combined with the federal (1,200 tax credit, this means **at least )1,650 in verified savings**—and potentially closer to $2,000 if you qualify for duct sealing rebates.
➡️ Check details at CenterPoint Energy Rebates.
2. Check Income-Based Rebates
If you live in Indiana, you may qualify for even bigger savings through the HOMES rebate program:
- Below 80% AMI (Area Median Income): Up to $18,000, covering 100% of costs.
- Above 80% AMI: Up to $4,000, covering 50% of costs.
Ohio doesn’t have as many statewide rebates, but many utility-specific incentives are available—always check your provider’s energy-efficiency programs.
3. Choose Eligible Materials
Not all insulation qualifies. To maximize credits, use ENERGY STAR®-certified products with the right R-values for your climate zone. Qualifying options include:
- Spray foam insulation
- Blown-in cellulose or fiberglass
- Foam board and rigid panels
- Certain insulation batts and rolls
4. Hire a Certified Contractor
DIY projects may not qualify for rebates or tax credits. A certified installer ensures your insulation meets program standards and provides the documentation you’ll need for tax filing.
5. Save All Documentation
Keep everything organized:
- Itemized receipts
- Manufacturer’s certification statements
- Product R-value and installation details
You’ll need these for both your tax return and rebate applications.
6. Combine Credits with Rebates
Stacking incentives is the smartest way to maximize savings. For example:
- Federal 25C credit: $1,200
- CenterPoint attic rebate: $450
- Verified savings = $1,650
- Potential duct sealing rebate: may add up to $350
- Total possible savings: (1,650–)2,000
7. Plan Your Timing
The 25C tax credit ends in 2025. If you delay, you may lose the opportunity for hundreds (or thousands) in savings. Consider phasing larger upgrades across 2025 to capture the maximum credit while it’s still available.
✅ The Bottom Line:
The 2025 insulation tax credit ends this year, but you still have time to combine federal credits and CenterPoint rebates for at least (1,650—and potentially up to )2,000—in savings. Act now to lock in your rebate, improve comfort, and reduce energy bills before the deadline passes.
