Updated federal rules
Calculate the historical federal residential credit for systems placed in service in 2024 or 2025, and see why a new residential installation in 2026 receives no federal Residential Clean Energy Credit.
The IRS states that the 30% Residential Clean Energy Credit covered qualified property installed from 2022 through December 31, 2025. It is unavailable for property placed in service after that date.
Potentially eligible if all IRS requirements were met.
No new federal residential credit under current law.
A taxpayer with an unused credit from eligible property placed in service by December 31, 2025 may be able to carry it forward, subject to IRS rules and the taxpayer's liability. Use the appropriate Form 5695 and tax-year instructions.
The federal residential credit ending does not automatically end state tax credits, rebates, property-tax exemptions or utility programs. Check the program administrator and DSIRE before relying on an incentive.
