No 30% Solar Tax Credit for 2026 Installs: What the IRS Says, and What a Salesperson's Promise Can Mean

No 30% Solar Tax Credit for 2026 Installs: What the IRS Says, and What a Salesperson's Promise Can Mean

It was November of last year. The salesperson at your kitchen table was clear: sign now, the panels would be on the roof before the new year, and you'd get 30% back at tax time. The crew didn't show until February. Then the inspection slipped, and the system wasn't switched on until spring.



Nobody mentioned that the date the panels went up was the date that decided the credit.

What the IRS says

The residential clean energy credit, Section 25D, was the 30% federal credit homeowners could claim for solar systems they owned. Congress ended it in the One Big Beautiful Bill Act, and the IRS's FAQ on the law puts it plainly:

• The credit isn't allowed for any expenditure made after December 31, 2025.
• If installation is completed after that date, the expenditure is treated as made after it, which prevents the taxpayer from claiming the credit.
• That holds even if you paid on or before December 31, 2025.

In other words, the date you signed and the date you paid don't control. The date the installation was completed does. A system paid for in December and finished in January gets no 25D credit. See the IRS's Residential Clean Energy Credit page for the current status.

Who this hits

• Homeowners who signed in 2025 and whose installation finished in 2026. Installer backlogs, permit delays, and bankruptcies all pushed projects across the line. See our Freedom Forever guide for what happened to one company's customers.
• Anyone who signed in 2026 and was still told they'd get 30% back. For a system you own and complete in 2026, there is no federal homeowner credit to claim.
• Loan customers whose low payment was built on the credit. If your payment was set assuming a lump-sum prepayment from the credit, see why a solar payment can jump at month 19.
• Anyone pitched "pay now, install later." The timing of the payment doesn't preserve the credit.

Leases and PPAs are different

When a company owns the system on your roof under a lease or PPA, it doesn't pass the homeowner credit to you, because you never owned the equipment. The provider may claim a business credit, Section 48E, and trade sources report that solar projects had to begin construction by July 4, 2026 or be placed in service by December 31, 2027 to qualify. Whether any of that benefit reaches you depends on the price and terms in your contract, not on a tax line you file. Our guide to escalator clauses explains how the contract's own terms drive what you pay over time.

What a broken promise can mean

Losing the credit isn't automatically a legal claim. What it can mean depends on the facts:

• What was said, and what was written. A written proposal that promises a specific credit is stronger than a verbal comment. CSLB's own advice is to get every sales claim in writing.
• Whether the price or loan was built on the credit. If the numbers only worked with the credit, that matters.
• When the installation was actually completed, and why. A delay caused by the company is different from one caused by a homeowner.
• How the sale was financed. If there's a loan, the FTC Holder Rule may let you raise the seller's conduct against the lender.

We can't promise a result, and your own tax situation is a separate question for a tax professional.

Proving when the installation was completed

Because the IRS ties the credit to completion, the date matters, and records tell the story. The IRS speaks of installation being completed, and a tax professional can tell you how to read that for your facts. Gather:

• The final inspection sign-off from your city or county.
• The installer's completion or commissioning paperwork, if you got any.
• Timestamped photos of the finished system.
• Your utility's permission-to-operate letter, which is a different date from completion but belongs in the file. See our Permission to Operate guide.
• Messages about delays, especially anything showing why the schedule slipped.

What to gather for a review

• Your proposal and every page that mentions a tax credit.
• Texts, emails, and anything the salesperson sent.
• Your contract date, payment dates, and loan documents.
• The installation timeline and the records above.

Our documentation checklist covers how to keep it organized.

Careful with the tax side

If you're thinking about filing for a credit, talk to a tax professional first, because claiming a credit you don't qualify for can cause its own problems. Our guide to the tax-extension deadline explains the deadline that has now passed for 2025 installations.

Questions about the solar tax credit and your contract

Can I still claim the credit if I paid in 2025 but the install finished in 2026?

According to the IRS FAQ, no. If installation is completed after December 31, 2025, the expenditure is treated as made after that date, even if you paid before it. Talk to a tax professional about your situation.

Does a lease or PPA provider's credit lower my payment?

Not automatically. The provider claims its own credit, and any benefit to you is whatever the contract's price and terms provide. Read the rate and escalator, and ask what was assumed.

Can I get compensation for a credit I lost because of a delay or a promise?

It depends on what was promised, who caused the delay, and what the contract says. We can review your documents and tell you whether it's worth pursuing.

Told you'd get 30% back on a system finished in 2026, or lost the credit to a delay?

Send us your proposal, your contract, and your installation records and we'll tell you where you stand, usually in one 15-minute call.
