THE SHORT ANSWER
As checked September 9, 2026, the IRS says the Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. A new 2026 homeowner installation should not be budgeted using an assumed 30% Section 25D credit. [1]
Find every place the assumed benefit appears
Look beyond the headline net price. Search the proposal for a tax-credit deduction, an expected principal payment, a re-amortization assumption or a later payment that depends on making a lump-sum contribution. Ask for the gross installed price and the payment schedule without the assumed homeowner credit. Removing one label from the first page does not repair a financing illustration that still relies on it.
Do not confuse a past payment with completed installation
The IRS transition FAQ explains that an expenditure is generally treated as made when original installation is completed. Its example rejects a prepayment made by the end of 2025 when installation is completed afterward. [2] If you have a project crossing that deadline, take the actual contract, payment and completion records to a qualified tax adviser. Do not backdate documents or treat this article as a determination of your tax return.
Separate old-credit carryforwards from a new purchase
An unused credit from a qualifying earlier project is a different question from eligibility for a new 2026 installation. Ask your adviser about the former using your prior returns and project records. It should not be represented as a new credit created by the system you are buying today. Keep any independently verified tax position separate from the contractor’s equipment and installation scope.
Keep third-party ownership claims specific
A lease or prepaid lease has a different owner and contractual structure from a homeowner purchase. Do not assume a provider’s claimed business incentive becomes a tax credit payable to you, or that it creates a particular discount. Ask for the actual price, obligations and written terms. Origin should explain the offered payment path without promising a tax result that belongs to a separate taxpayer or program.
Re-evaluate the purchase on current inputs
Request a corrected comparison of solar obligations and the remaining utility bill, with no unverified incentive included. If a provider identifies another current program, ask for the official rules and your eligibility evidence before adding it. Solar’s suitability still depends on the home and complete scope. An outdated tax assumption is a reason to correct the budget, not to replace it with an equally unsupported savings promise.
