Federal solar tax credit for homeowners: what ended and what is left

As of 9 Oct 2026, the federal tax credit for home solar has ended for installations completed after 31 December 2025. The Internal Revenue Service (IRS) says the 30% Residential Clean Energy Credit is not available for property placed in service after that date. Unused credit from an earlier installation can still be carried forward.

What exactly ended on 31 December 2025?

Under tax code section 25D(h), the Residential Clean Energy Credit does not apply to expenditures made after 31 December 2025. It was a federal income tax credit equal to 30% of the costs of new, eligible clean energy property for your home, such as solar electric panels.

The IRS says it covered installations from 2022 through 31 December 2025. Congress ended it in section 70506 of Public Law 119-21, commonly called the One Big Beautiful Bill Act, signed on 4 July 2025. Before that law, the credit was set to run through 2034, stepping down to 26% in 2033 and 22% in 2034.

Expenditure made
The date the law counts a cost as spent. Under section 25D of the tax code, that is when the original installation is completed, not when you sign or pay. For a new or rebuilt home, it is when you first use the home.
Nonrefundable credit
A credit that lowers your tax to zero but never pays you a refund. The IRS says the amount you receive can’t exceed the amount you owe in tax.
Carryforward
The part of a credit your tax bill could not use in one year, applied against your tax in a later year.

Which date counts: signing, paying or finishing the installation?

Under section 25D of the tax code, the day your installation is completed counts, not the day you signed or paid. The statute treats an expenditure as made when the original installation of the item is completed.

The day your installation is completed is the date that counts, not the day you signed or paid.
  • Date allows it Installation completed on or before 31 December 2025
  • Not eligible Paid in full by 31 December 2025, installation completed in 2026

The IRS answers the common case in its frequently asked questions (FAQ). Asked whether a credit can be claimed for property installed after 31 December 2025 if the taxpayer paid on or before that date, it answers no. The Congressional Research Service (CRS) gives the plain version: equipment whose installation starts in 2025 and finishes in 2026 does not count for the credit.

For a new or rebuilt home, the date is when you first use the home. If your installation finished close to the deadline, find the completion date in your installer’s paperwork.

Which situations did the credit cover?

Two questions sort most rows: was the installation completed by 31 December 2025, and does the taxpayer own the system?

Which situations the Residential Clean Energy Credit covered, by installation date and ownership (IRS and statute, checked 9 Oct 2026)
SituationFederal creditWhy
Installation completed on or before 31 December 2025Date allows itThe IRS says to claim the credit for the tax year the property is installed, not merely purchased. The home and the property must also meet the credit’s other rules.
Signed or paid in full by 31 December 2025, installation completed in 2026Not eligibleThe IRS FAQ and the statute count the date installation is completed, not the date of signing or payment.
New or rebuilt home you first use after 31 December 2025Not eligibleFor construction or reconstruction, the expenditure is made when your original use of the structure begins.
Battery storage completed for your home after 31 December 2025Not eligibleThe IRS lists battery storage technology among the property the same credit covered, so the same last date applies.
Used panels already on a home you buyNot eligibleThe IRS says used (previously owned) clean energy property is not eligible.
Credit left over from an earlier installationCarries forwardThe IRS says unused credit can be carried forward to reduce tax in future years.
Lease or power purchase agreement (PPA)Not yours to claimThe IRS says the installation must be owned, not rented or leased, by the taxpayer who claims the credit.

What is left for anyone who installed by 31 December 2025?

If your installation was completed by 31 December 2025, the IRS says to claim the credit on Form 5695 for the tax year of installation. Because the credit is nonrefundable, any amount your tax could not use carries forward.

The CRS says a carryforward stays usable until the whole credit is used, and that the 2025 law did not change the carryforward rules. Form 5695 for 2025 has line 12 for a carryforward from 2024 and line 16 for the amount carried to 2026.

Checked 9 Oct 2026.

What about a lease or a power purchase agreement (PPA)?

A customer who leases a system or signs a PPA does not claim the homeowner credit. The IRS says the installation must be owned, not rented or leased, by the taxpayer who claims it.

The Federal Trade Commission (FTC) says the same: with a lease or a PPA you don’t own the system, so the tax credits go to its owner.

What should you ask when a quote mentions a federal credit?

Ask which credit the quote subtracts and when installation will be completed. The IRS says the homeowner credit is not available for property placed in service after 31 December 2025. Put the questions to every installer, in writing.

The Treasury Department’s advisory poses two questions about any credit a salesperson mentions: are you really eligible, and is it already in the total cost the installer or lender shows?

  • Which federal credit the quote subtracts, and the rule that allows it
  • The date installation will be completed, written in the quote or the contract
  • The total before any credit or rebate is subtracted
  • Whether the monthly payment or a “net cost” assumes a credit, and what changes if the credit does not arrive
  • Who claims each incentive the quote mentions, you or the company
  • Which state, utility or city programs the quote assumes, and the agency that publishes each

Worked example with made-⁠up numbers

Two short examples show how a credit line changes a quote and how a carryforward works. Every number is made up for practice. None is a real quote, a real tax return or a guide to what any installer charges or any household owes.

Example 1: a 2026 quote that subtracts a credit

A made-up quote for an installation to be completed in 2026 shows a total of $20,000, a line for a 30% federal credit and a “net cost” below it.

Made-up numbers: the same quote as written and with the credit line removed
LineAs written on the quoteWith the credit line removed
Total before any credit$20,000$20,000
Less 30% federal credit (30% × $20,000)−$6,000$0
“Net cost”$14,000$20,000

The $14,000 depends on a credit the IRS says is not available for an installation completed in 2026. The number to compare with other quotes is the total before any credit.

Example 2: a carryforward across two tax years

A made-up system is completed on 20 November 2025 with $20,000 of eligible costs, so the credit is 30% × $20,000 = $6,000. The homeowner owes $4,500 of tax before credits for 2025 and $5,000 for 2026.

Made-up numbers: how a $6,000 credit is used across two tax years
Tax yearTax before the creditCredit usedCredit left to carry forwardTax after the credit
2025$4,500$4,500$1,500$0
2026$5,000$1,500$0$3,500

For 2025, $6,000 − $4,500 = $1,500 is left over and carried to 2026. For 2026, $5,000 − $1,500 = $3,500.

Where do state and utility incentives come in?

What else applies depends on your state and your utility, so each market has its own page. The Treasury Department’s advisory says some states have incentive programs or rebates and suggests contacting your state’s environmental agency or energy office before you sign.

Questions about the federal solar tax credit

Is there a federal solar tax credit in 2026?

Not the homeowner credit. The IRS says the Residential Clean Energy Credit is not available for property placed in service after 31 December 2025. Unused credit from an earlier installation can still be carried forward.

Does a deposit paid in 2025 count?

Not if the installation is completed in 2026. The IRS says an expenditure is treated as made when the original installation is completed, so the payment date does not decide it.

What if an installer says the federal credit is still available?

Ask which credit, under which rule, and get the answer in writing. The Treasury Department advises being wary of anyone who says you can use tax credits to reduce the cost of the panels without confirming your eligibility.

Did the credit for home batteries end too?

Yes. Battery storage technology of at least 3 kilowatt-hours (kWh) was part of the same credit, so it has the same last day.
