Federal Energy Efficient Home Improvement Tax Credit (25C)

About This Program

The IRS Section 25C tax credit provides 30% of qualifying upgrade costs each year, up to $3,200 annually ($1,200 for insulation, windows, doors, and audits; $2,000 for heat pumps and water heaters). Unlike a deduction, this directly reduces federal income tax owed. The credit resets each tax year through 2032, allowing multiple years of improvements to capture the full benefit.

30% of upgrade cost, up to $3,200/year. A $10,667 in upgrades per year captures the full $3,200 credit. Stacks with Xcel and HEAR rebates (rebates reduce the cost basis before calculating the credit).
