Who is eligible?

When the credit is available?

The 25C credit is available for purchases on or after January 1, 2024, through December 31, 2032

How to claim the credit

You may claim the credit when you file your tax return by submitting Form 5695, Residential Energy Credits. You must claim the credit for the tax year when the project is installed, not purchased. The value of the credit will be reduced from the amount of taxes you owe. The credit is not refundable, so the credit amount you receive cannot exceed the amount you owe in tax.

When calculating your credit, you may need to subtract subsidies, rebates, or other financial incentives from your qualified property expenses because they are considered a purchase price adjustment.
