Federal tax credits

The federal 25C credit ended for property placed in service after December 31, 2025, and the 25D credit for installations completed after that date.

What this means for a quote

25C was the Energy Efficient Home Improvement Credit (heat pumps, insulation, windows and doors, home energy audits). 25D was the Residential Clean Energy Credit (solar, batteries, geothermal). For 25D the IRS counts the expense as made when the installation is finished, so paying early does not help if the work is finished later.

If a quote counts a federal 25C or 25D credit toward the price for work finished in 2026 or later, ask the contractor to show you the IRS rule they are relying on. This is general information, not tax advice; a tax preparer can confirm your situation.
