Through the end of 2025, a homeowner could take a federal tax credit of 30% of the qualifying costs of heat pumps, insulation, windows, solar systems and more, within the credits' limits. For any job installed today, "you get 30% back" is wrong. Public Law 119-21 of July 4, 2025, which the IRS notes is commonly known as the One, Big, Beautiful Bill, ended both federal home energy credits for work after 2025. Customers still ask, and some have read about the credit in a brochure or on an old web page. Here is what ended, what may still be available, and what you can say without making a claim you cannot stand behind.
What ended, and when
Two credits are gone. Section 70505 of the law ended the Energy Efficient Home Improvement Credit (section 25C of the tax code) for property "placed in service after December 31, 2025." Section 70506 ended the Residential Clean Energy Credit (section 25D) "with respect to any expenditures made after December 31, 2025." The IRS confirmed both dates in its August 2025 questions and answers on the law (FS-2025-05).
| Credit | What it covered | When it stopped |
|---|---|---|
| Energy Efficient Home Improvement Credit (25C) | 30% of qualified costs, up to $2,000 a year for heat pumps, heat pump water heaters and biomass stoves and boilers, and up to $1,200 a year for the rest: insulation and air sealing, windows and skylights ($600), exterior doors ($250 each, $500 total), central air conditioners, furnaces, boilers and water heaters ($600 each) and home energy audits ($150) | No credit for property placed in service after December 31, 2025 |
| Residential Clean Energy Credit (25D) | 30% of the cost of solar panels, solar water heaters, wind turbines, geothermal heat pumps, fuel cells and battery storage of at least 3 kilowatt hours | No credit for expenditures made after December 31, 2025 |
One detail catches people out. For the solar credit, paying early did not help. The IRS says that under section 25D(e)(8)(A) an expenditure "is treated as made when the original installation of the item is completed," so a system paid for in December 2025 but finished in January 2026 gets no credit. For the home improvement credit, the test is when the property was placed in service, which the IRS ties to installation: the credit is claimed "for the tax year when the property is installed, not merely purchased."
The customer whose job was finished in 2025
A job installed in 2025 belonged on the customer's 2025 return, on Form 5695. For home improvement property placed in service in 2025, the IRS adds a condition: no credit unless the item was made by a qualified manufacturer and the taxpayer reports its Qualified Manufacturer Identification Number (QMID). Insulation and air sealing materials are the exception. If a 2025 customer asks you for paperwork, give them the invoice with the install date, the make and model of each item, and the QMID where the manufacturer provides one. What they can claim is a question for their tax preparer, not for you.
What a customer may still get
The federal credits are gone, but the customer's question ("is there any help paying for this?") still has answers in many places. They are just local, and they change.
If your state runs a rebate that is paid through contractors, find out from the State Energy Office how a contractor takes part before you promise a customer anything about it.
What you may say, and what you should stop saying
The Federal Trade Commission Act makes "unfair or deceptive acts or practices in or affecting commerce" unlawful (15 U.S.C. 45(a)(1)). The FTC's advertising guide for small businesses puts the standard simply: advertising "must be truthful and non-deceptive," advertisers "must have evidence to back up their claims," and an ad is deceptive if it is likely to mislead consumers acting reasonably and the point is "material," meaning important to the decision to buy. The FTC looks at implied claims as well as express ones. A tax credit is about as material as a sales point gets.
Lines to retire now, wherever they appear:
Lines you can stand behind:
A worked example
Say an HVAC contractor still uses a heat pump estimate template from 2024 with a line reading "Estimated federal tax credit: −$2,000" and a bottom line net of it. On a system installed this winter, that line is false, and the net price is a price the customer will never pay. The fix takes an afternoon: delete the credit line, show the installed price, and add a short note naming the state energy office program and the utility rebate page with "eligibility set by the program." If the template also showed a monthly payment, the financing rules apply to that too; see advertising financing.
The places the old line hides
Each trade has its own version of the sale: our pages on HVAC, insulation, windows and doors and solar show how those jobs can be priced on your own website. For insulation, what you must tell a customer about R-value is a separate set of rules, covered in the FTC's R-value rule.
