The Solar Tax Credit Expired: What It Means for Your Contract and Your Options

For nearly two decades, homeowners who bought solar could claim 30% of the cost back on their federal taxes. That era ended on December 31, 2025. If a salesperson told you the federal tax credit would make your system “free” or nearly free — and you are now discovering the math does not work that way — you are far from alone, and depending on when and how you were sold, you may have a claim. This guide explains what actually happened to the solar tax credit, who can still claim it, and why the way it was sold has become a source of legal disputes.

What Happened to the 30% Solar Tax Credit

The federal residential solar tax credit — formally the Section 25D Residential Clean Energy Credit — let homeowners who purchased a solar system claim 30% of the cost against their federal income taxes. Under the Inflation Reduction Act of 2022, it was scheduled to stay at 30% through 2032 before gradually stepping down. That changed abruptly. The One Big Beautiful Bill Act (Public Law 119-21), signed into law on July 4, 2025, terminated the credit nearly a decade early, with no phase-down and no transition period.

The result is stark. A homeowner who buys a solar system with cash or a loan and has it installed in 2026 or later receives zero federal tax credit — down from 30% just weeks earlier. The credit did not shrink gradually; it went from 30% to nothing on January 1, 2026.

The Critical Detail: “Expenditure” Means Installation Completed

One point causes enormous confusion, and it matters for anyone who signed in late 2025. The law cuts off the credit for expenditures made after December 31, 2025 — and the IRS has clarified that an expenditure is treated as made when the original installation is completed, not when you signed a contract or paid a deposit. So if you signed in 2025 but your system was not fully installed and placed in service until 2026, you do not qualify, even though you may have been told at signing that you would get the 30% credit. That gap between the sales promise and the IRS rule is exactly where many disputes now live.

Who Can Still Claim the Credit

The repeal is forward-looking, so several groups are unaffected or still have options:

• Homeowners who installed by December 31, 2025. If your system was installed and placed in service by the deadline, you can still claim the 30% credit on your 2025 federal return using IRS Form 5695. The law does not retroactively strip credits from those who already qualified.
• 2025 installers with low tax liability. Because the credit is nonrefundable, if your 2025 tax liability was too low to use the full amount, the unused portion can generally carry forward to future tax years until used — the IRS has confirmed the carry-forward remains in effect.
• Lease and PPA customers. If you do not own the system — a lease or power purchase agreement — the third-party owner may still claim a business credit under Section 48E and, in theory, pass some savings along through pricing. You do not claim it yourself.
• Homeowners in states with their own incentives. Many state programs and utility rebates survived the federal change and continue to reduce costs in some markets.

Why the Tax Credit Became a Legal Problem

Here is where the expiration intersects with solar fraud. “The tax credit will cover a big chunk of the cost” was one of the most common selling points in residential solar — and it was frequently misrepresented even while the credit existed. Now that it has expired for owned systems, the misrepresentations have become both more common and more consequential. Salespeople have been accused of the following, all of which can support a solar fraud or deceptive-practices claim:

Telling 2026 Buyers They’ll Get a Credit That No Longer Exists

The most serious version: a homeowner buying an owned system in 2026 is told they will receive a 30% federal credit that, in fact, was eliminated on January 1, 2026. If your purchase decision and your financing were built around a credit you were never eligible for, that is a material misrepresentation.

Misrepresenting the Credit as a Rebate or Guaranteed Cash

Even when the credit existed, it was a nonrefundable tax credit that depended on your tax liability — not a check in the mail and not a guaranteed discount. Homeowners were routinely told the “government would pay” 30%, then discovered at tax time they could not use all or any of it because their tax liability was too low. Loan structures were often built around a credit the homeowner never fully received.

The “Balloon Payment” Trap

Many solar loans were structured assuming the homeowner would apply the 30% tax credit as a lump-sum payment against the principal within 12 to 18 months. When the credit never arrived — because the homeowner could not use it, or in 2026 was never eligible — the loan re-amortizes at a much higher monthly payment than promised. Homeowners describe payments jumping substantially once the assumed credit fails to materialize.

Leases and PPAs: The One Place a Credit Still Survives

There is a nuance worth understanding, because it is both a legitimate option and a new source of confusion. While homeowners who buy a system get zero federal credit in 2026, the credit did not disappear from the solar economy entirely — it moved to the business side. When a third party owns the system, as in a lease or a power purchase agreement, that owner can claim a business energy credit under Section 48E, and may pass some of the value along through lower pricing.

This creates a real risk of a new misrepresentation. A salesperson may now steer a homeowner into a lease or PPA by saying “you still get the 30% credit” — when in fact the homeowner does not get it at all; the installer or investor does. The homeowner simply gets whatever pricing the company chooses to offer. If you were pushed toward a lease or PPA in 2026 on the promise that you would personally receive a federal tax credit, that framing is misleading, and the long-term cost of a 20-year PPA with an escalator can far exceed any pricing benefit. It is worth reading any 2026 lease or PPA with that in mind.

If You Are Being Sold Solar Right Now in 2026

Because the rules changed so recently, a lot of sales material — and a lot of salespeople — have not caught up, whether through genuine lag or deliberate omission. If you are considering solar in 2026, protect yourself with a few simple checks. First, treat any claim of a 30% federal tax credit on an owned system as a red flag: for a purchase, it no longer exists. Second, get every savings and credit claim in writing, not just verbally, so there is a record if the pitch and the paperwork diverge. Third, if a company assures you the credit still applies, ask them to point to it in writing and confirm it with your own tax professional before signing anything.

None of this means solar cannot make sense in 2026 — state incentives, rising utility rates, and shorter payback periods still make it worthwhile in many markets. It means the single biggest selling point of the last decade is gone for buyers, and any sale that still leans on it deserves scrutiny. If it turns out a credit promise drove your decision, that is precisely the kind of claim an attorney can evaluate.

Signs the Tax Credit Was Misrepresented to You

You may have a claim tied to how the credit was sold if any of these apply:

• You bought an owned system in 2026 and were told you would receive a 30% federal tax credit.
• You signed in 2025 but installation slipped into 2026, and no one told you that would disqualify you.
• You were told the credit was a guaranteed rebate or cash payment rather than a nonrefundable credit tied to your tax liability.
• Your loan payment jumped after 12 to 18 months because an assumed tax-credit paydown never happened.
• You could not actually use the credit because your tax liability was too low, contrary to what you were told.
• The projected savings you were shown depended on a credit you never received.

If any of these ring true, the issue is not really the tax law — it is what you were told about it. That is a solar contract dispute question, and it may be actionable regardless of the credit’s expiration.

What You Can Do

If the tax credit was misrepresented in your sale, several paths may be open:

1. Talk to a tax professional first about your actual eligibility — whether you installed in time, and whether any carry-forward applies. This establishes what you were truly entitled to.

2. Compare the promise to the paperwork. What were you told about the credit verbally versus what the contract and loan documents actually say?

3. Check your loan structure for an assumed tax-credit paydown and a payment that re-amortizes if it is not made.

4. Consider cancellation or misrepresentation remedies. A material misrepresentation about the credit can support canceling the contract or a deceptive-practices claim, and where the loan is home-secured, TILA rescission may apply.

5. File complaints and get a review. Your state attorney general and a solar attorney can each assess whether the sale crossed the line.

One caution that applies to every solar dispute: do not simply stop paying your loan while you sort this out. Missing payments can trigger default before your claim is resolved. Sequence any decision with a qualified attorney.

Frequently Asked Questions

Is the solar tax credit gone?

For homeowners who buy and own a system, yes. The Section 25D Residential Clean Energy Credit expired December 31, 2025 under the One Big Beautiful Bill Act, with no phase-down. A system you purchase and install in 2026 or later receives no federal residential tax credit. Lease and PPA systems, owned by a third party, may still capture a credit on the owner’s side.

I installed in 2025 — can I still claim it?

Yes. If your system was installed and placed in service by December 31, 2025, you can claim the 30% credit on your 2025 federal return using IRS Form 5695. The repeal is forward-looking and does not strip credits from those who already qualified.

I signed in 2025 but was installed in 2026. Do I qualify?

Generally no. The IRS treats the expenditure as made when installation is completed, not when you signed or paid a deposit. If installation finished after December 31, 2025, you do not qualify for Section 25D, even if you signed earlier.

The salesperson said I’d get a 30% credit in 2026. Is that true?

No. For an owned system purchased in 2026, there is no federal residential tax credit. If a 2026 purchase was sold to you on the promise of a 30% credit, that is a misrepresentation and may support a claim.

My loan payment jumped after a year — why?

Many solar loans were structured assuming you would apply the 30% credit as a lump sum against principal within 12 to 18 months. If that paydown never happened — because you could not use the credit or were never eligible — the loan re-amortizes at a higher payment. If the credit was misrepresented, this may be actionable.

Can I cancel my solar contract because the tax credit was misrepresented?

Possibly. A material misrepresentation about the credit can support cancellation, a deceptive-practices claim, or — on a home-secured loan — TILA rescission. Whether it applies depends on what you were told and your documents, which an attorney can review.

Is this tax advice?

No. This page is educational and explains how the credit’s expiration intersects with solar sales practices. For your actual tax eligibility, consult a qualified tax professional; for a possible misrepresentation claim, consult an attorney.

Were You Promised a Tax Credit You Didn’t Get?

If you bought solar based on a tax credit that never materialized — or were sold a 2026 system on the promise of a 30% credit that no longer exists — the problem is not the tax law, it is what you were told. Credible Law connects homeowners nationwide with independent, licensed attorneys who handle deceptive solar sales, contract cancellation, and related claims. An attorney can review what you were promised against what you received and tell you whether you have a case. There is no cost to be matched with counsel.
