Federal Tax Credit — 25C Inflation Reduction Act

Under the Inflation Reduction Act, homeowners who install qualifying insulation in an existing primary residence can claim a 30% federal tax credit on the cost of materials (labor not included), up to $1,200 per tax year.

What Qualifies

• Open-cell and closed-cell spray foam insulation ✓
• Attic insulation ✓
• Crawl space insulation and encapsulation ✓
• Wall cavity insulation ✓
• Must be installed in your primary residence (not rental or commercial)
• Claim on IRS Form 5695 when filing your taxes

The $1,200 cap resets each tax year — so if your project cost exceeds the cap, you can spread qualifying improvements across multiple years.

KUB (Knoxville Utilities Board) Rebate Program

As a TVA distributor, KUB offers its own rebate program for Knoxville customers. Current rebates include:

• Air sealing combined with insulation upgrades: up to $400
• Attic insulation to R-38 or above: up to $200
• Crawl space insulation: rebate amounts vary by project
