Homeowners and car shoppers who spent the last few years factoring a federal tax credit into the price of a heat pump, a solar array or an electric vehicle are now shopping without one. Congress shut down three separate federal credits through the same law last year, and 2026 is the first calendar year households have had to absorb the full cost of a heat pump, an insulation job, a solar installation or an EV purchase with no year-end write-off waiting on the other side. The credits did not shrink on a phase-out schedule, the way some tax breaks fade out gradually over several years. They stopped on a fixed date, for good, and the 2025 tax return is the last one that can include them.
The Home Energy Credits Covered Up to $3,200 a Year, Then Stopped
Two separate provisions made up what many households treated as one home energy tax break, and both ran on the same calendar-year deadline. Together they could return several thousand dollars on a single project, which made the timing of a home energy upgrade a real financial decision and not just a scheduling one.
The Energy Efficient Home Improvement Credit paid 30% of the cost of insulation, air sealing and home energy audits, capped at $1,200 a year, with heat pumps, heat pump water heaters, and biomass stoves and boilers eligible for a separate $2,000 annual cap, according to the IRS’s Energy Efficient Home Improvement Credit page. The Residential Clean Energy Credit, which covered solar panels, solar water heating and geothermal heat pumps, paid 30% of the cost with no annual or lifetime dollar cap at all, per the IRS’s Residential Clean Energy Credit page. Both credits ran through the end of 2025 and then stopped by statute. The IRS’s own Working Families Tax Cuts summary, last reviewed Aug. 20, 2026, states that the Energy Efficient Home Improvement Credit under Sec. 70505 of the new law is “not allowed for property placed in service after Dec. 31, 2025,” and that the Residential Clean Energy Credit under Sec. 70506 is “not allowed for expenditures made after Dec. 31, 2025.” A household that finished a heat pump and insulation project before that date could still claim close to $3,200 back between the two credits. The identical project finished a few weeks later, in January 2026, qualifies for nothing.

Installation Date Decided Who Still Qualified, Not the Purchase Date
The cutoff was never about when a homeowner signed a contract or paid a deposit. Both home energy credits turn on when the equipment was actually installed and running, what the tax code calls being “placed in service,” not on when it was ordered or paid for. That distinction mattered most for any project that stretched over weeks or months: a supply delay, a permitting backlog or a contractor’s schedule that pushed a completed installation from December into January could take the entire credit with it, even if the homeowner had signed and paid months earlier. There is no partial credit and no extension for work still in progress on Dec. 31, 2025. Homeowners who are only now checking on a project finished in early 2026 sometimes assume a delay of a few weeks doesn’t matter for a multi-thousand-dollar credit; under this law, it does.
The EV Credit Ended Three Months Earlier, on September 30
Vehicle buyers lost their credit on a different, earlier calendar. The New Clean Vehicle Credit, worth up to $7,500 toward a new plug-in EV or fuel-cell vehicle, and the Used Clean Vehicle Credit, worth up to $4,000 for a qualifying used EV or fuel-cell vehicle bought for $25,000 or less from a licensed dealer, are described on the IRS’s new clean vehicle credit page and used clean vehicle credit page. Under Secs. 70501 through 70503 of the new law, both of those credits, along with the Qualified Commercial Clean Vehicle Credit, are “not allowed for any vehicle acquired after Sept. 30, 2025,” per the Working Families Tax Cuts summary. The vehicle credits use “acquired,” not “placed in service,” so a buyer who signed a binding purchase contract and made a payment on or before Sept. 30, 2025, could still lock in the credit even if the vehicle wasn’t delivered until later. Anyone who acquired a qualifying vehicle for the first time on Oct. 1, 2025, or after gets nothing from these three credits, regardless of the vehicle’s fuel economy or battery size.
Both Deadlines Trace to the Same Law, Signed in July 2025
The Dec. 31 and Sept. 30 cutoffs were not two different policy fights. Both come from the same reconciliation bill, H.R. 1, which the official congressional bill tracker shows was signed into law on July 4, 2025. Lawmakers gave vehicle buyers a runway of roughly three months from that signing date, and gave home energy projects roughly six months, before either set of credits disappeared, which is part of why the second half of 2025 saw a wave of EV purchases and home energy installations rushed to beat the clock. That runway is now gone on both fronts. Nothing on the IRS’s own summary page schedules a replacement federal credit for either category, and that page has been reviewed as recently as Aug. 20, 2026, with no update reinstating any of the three credits.
