Quick answer: Section 25D, the residential solar credit, has no recapture schedule. Unlike the business credit under Section 48, there is no five-year clock that claws a percentage back if something changes. But if you cancel and receive a refund of what you paid, the expenditure that justified the credit was never really made, and you generally must amend the return for the year you claimed it and repay the portion attributable to the refunded amount. Separately, and far more importantly for anyone signing in 2026: Congress repealed Section 25D for installations completed after December 31, 2025. If your system was finished in 2026, there is no federal credit to claw back because there was never a credit to claim.
First: does the credit even exist for your install?
This is now the threshold question, and it catches people out because the change is recent and the sales scripts have not been updated.
Public Law 119-21, enacted July 4, 2025, repealed the Residential Clean Energy Credit under Internal Revenue Code Section 25D for expenditures made after December 31, 2025. The IRS has published guidance confirming this and, importantly, defining what "made" means: an expenditure is treated as made when the original installation is completed: not when you signed, not when you paid the deposit, and not when the panels were delivered.
The date that matters is your permission-to-operate or installation-completion date, not your contract date. A homeowner who signed in October 2025 but whose system was not finished until February 2026 generally gets no Section 25D credit at all. In our assessment this is the single most common tax surprise facing 2026 solar customers, and it is one that many homeowners will not discover until they file.
If your installation was completed on or before December 31, 2025, the credit rules that applied then still apply to you, including the ability to carry unused credit forward into later tax years. The repeal is forward-looking; it does not reach back and cancel a credit you properly earned.
Section 25D has no recapture schedule
A great deal of anxiety on this topic comes from people reading about the business solar credit and assuming it applies to their house. It does not.
The commercial investment tax credit under Section 48 carries an explicit five-year recapture rule. If the property is disposed of or stops qualifying within five years, a percentage of the credit is recaptured on a sliding scale. 100% in year one, decreasing by 20% each year. That schedule is real, and it is what most "solar tax credit clawback" articles are actually describing.
Section 25D, the residential credit, contains no equivalent provision. There is no five-year holding period, no sliding scale, and no automatic recapture event. Selling the home does not trigger repayment. Removing the panels does not, by itself, trigger repayment.
Practical read: if you properly claimed the credit on a system that was installed and paid for, and nothing about that transaction is later unwound, the IRS generally has no recapture mechanism to invoke against you under Section 25D. The exposure comes from a different direction entirely, which is the next section.
What actually triggers repayment: the refund
The credit is calculated on qualified expenditures you actually made. That is the hinge. If a cancellation, rescission, settlement, or chargeback returns money to you, then to the extent of that refund you did not incur the expenditure the credit was based on.
Two situations behave very differently:
Refund in the same tax year you paid. Generally the cleanest case. You net the refund against your expenditures and claim the credit on what you actually spent, if anything. No amendment is needed because the return was never filed with the wrong number.
Refund in a later tax year, after you already claimed. This is where an amended return generally comes in. The return you filed claimed a credit on money that was subsequently returned to you. The usual remedy is to file an amended return (Form 1040-X) for the year of the original claim, recompute the credit on the corrected expenditure figure, and repay the difference. Potentially with interest.
A partial refund produces a partial adjustment. If you paid $30,000, claimed $9,000, and later recovered $10,000 in a settlement, the credit is generally recomputed on $20,000 of qualified expenditure rather than being wiped out entirely.
Do not simply keep quiet and hope. Solar settlements and cancellations increasingly generate paperwork that flows to the IRS, and the arithmetic is not hard for anyone who looks. In our assessment the far better posture is to have a CPA compute the adjustment and file it deliberately, rather than to leave an unamended return sitting there.
Four cancellation scenarios and the tax result
1. You cancelled within the cooling-off window, before installation. No installation was completed, so no expenditure was ever "made" for Section 25D purposes and no credit was claimable in the first place. If a deposit is refunded, there is generally nothing to report. This is the cleanest exit there is, which is why the cooling-off window matters so much.
2. System installed in 2025, credit claimed, and you are now trying to exit. The credit itself is generally safe unless money comes back to you. Negotiate with that in mind: a $12,000 settlement may carry a tax consequence that a $12,000 reduction in your loan balance does not, and the two are not equivalent even though they look similar on a term sheet.
3. System installed in 2026. There is no Section 25D credit, so there is nothing to claw back. If the credit was part of the economics you were sold, that is a separate and potentially significant problem. See the next section.
4. Lease or PPA, any year. You never had the credit to begin with. In a lease or power purchase agreement the third-party owner holds the tax attributes, not you. If a salesperson told you that you would receive a 30% credit on a leased system, that statement was generally wrong at the time it was made.

If your salesperson promised a 2026 tax credit
This deserves its own section, because the repeal has created a gap between what many sales presentations still say and what the law now provides.
A 30% credit is not a rounding error in a solar proposal. On a $30,000 system it is $9,000, and it is frequently the number that makes the payback math work on the printed savings sheet. If that figure was presented to you as a benefit you would receive, and your installation completed in 2026 so that no credit was available, then the economics you agreed to were materially misstated.
That may matter well beyond your tax return. Misrepresentation of a material term is one of the more commonly raised grounds in solar contract disputes, and unlike a cooling-off claim it is not limited to the first few days after signing.
Preserve the evidence now. Save the proposal PDF, the savings projection, any text or email referencing the tax credit, and the financing worksheet. Screenshot anything in an app that may be updated later. Documentation of what you were shown at the point of sale is generally far more persuasive than a recollection of what was said.

What to do, in order
Step 1. Establish your completion date. Find the date installation was completed and, if applicable, your permission-to-operate letter. This single date determines whether Section 25D applies to you at all.
Step 2. Confirm what you actually claimed. Pull the Form 5695 filed with the relevant return and note the exact credit amount. Do not work from memory or from what the installer said you would get.
Step 3. Model the tax cost of any settlement before you accept it. Ask your CPA what a proposed refund does to the credit you already claimed. A settlement structured as a loan principal reduction may leave you better off than the same dollar amount paid to you directly.
Step 4. Amend deliberately if a refund lands. If money comes back in a later year, have the amendment prepared rather than waiting for correspondence.
Step 5. Treat a promised-but-unavailable credit as a contract issue, not just a tax issue. Your CPA handles the return. Whether you were sold something on false economics is a question for a consumer-rights attorney.
If a 30% credit was in your savings projection and you did not receive one, that gap may be worth pursuing. Get matched with a solar exit company. Free, no obligation.
Frequently Asked Questions
Do I have to pay back the solar tax credit if I cancel my contract?
Not automatically. Section 25D has no recapture schedule, unlike the business credit under Section 48. Repayment is generally triggered by receiving a refund of amounts you claimed the credit on. If a cancellation or settlement returns money to you after you already claimed, you generally must amend that year's return and repay the portion of the credit attributable to the refunded amount.
Is there still a 30% federal solar tax credit in 2026?
Not for residential systems. Public Law 119-21 repealed the Section 25D Residential Clean Energy Credit for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when the original installation is completed. If your system was finished in 2026, no Section 25D credit is available regardless of when you signed the contract.
My system was installed in 2026 but I signed in 2025. Which year counts?
The completion date generally controls, not the contract date. IRS guidance ties the expenditure to when the original installation is completed. A 2025 signature followed by a 2026 completion generally means no Section 25D credit. This catches a large number of homeowners whose installations were delayed.
Does selling my house mean I have to repay the solar tax credit?
Generally no. Section 25D contains no recapture provision tied to disposing of the property, which is a key difference from the commercial credit under Section 48. Selling the home does not by itself create a repayment obligation for a credit you properly claimed.
What if I have a lease or PPA instead of a loan?
You generally never had the credit. Under a lease or power purchase agreement the third-party system owner holds the tax attributes. If you were told you would personally receive a 30% credit on a leased system, that statement was generally inaccurate when it was made, which may be relevant to a misrepresentation claim.
