What Still Qualified Earlier in 2026
Two limited exceptions applied earlier in 2026 but have now also expired: Section 30C ran through June 30, 2026, and Section 45L applied to qualifying new homes acquired by that same date. As of this guide, both windows have closed, so no federal residential energy credits from this Act remain active for the rest of 2026. Check with a tax professional for the current status, since legislation can change.
State Rebates
In addition to federal tax credits, some states offer their own rebate programs for energy-efficient upgrades. These programs vary widely from state to state, so be sure to research your home's location and local utility providers for potential savings.
Filing Requirements
To claim federal home energy tax credits, you must file a completed Form 5695 with your annual tax return. Keep in mind that most residential credits ended after December 31, 2025, so be sure to review the specific requirements for each credit before filing.
Financing
Understanding the difference between tax credits, point-of-sale rebates, and loans can help homeowners make informed decisions.
- Tax Credits: Reduce your federal tax liability dollar for dollar.
- Point-of-Sale Rebates: Direct cash back at the time of purchase or installation.
- Loans: Borrow money with a low interest rate to finance energy-efficient upgrades.
Utility or state rebates can change the claimable cost, so it's essential to confirm details with a tax professional before making any decisions.
