25D Is Gone. 48E Is Not the Same Credit, for the Same Buyer.
Section 25D ended outright, not on a phase-down schedule, for any residential system installed on or after January 1, 2026. That was the credit a homeowner who owned their system claimed directly on their own federal return. Section 48E is a different credit, written for a different party. It remains available in 2026, but only to whoever owns the solar equipment, which in a residential context is almost always a third-party lease or PPA provider under a TPO structure, not the homeowner.
Who Actually Files for 48E
Because ownership sits with the lease or PPA provider, often financed through a tax-equity partner, that entity claims the credit on its own return. The homeowner in a TPO deal is not the taxpayer filing for 48E and never sees a form for it. That single fact is why a rep cannot promise a homeowner a specific rebate figure on a TPO deal: the credit belongs to the system owner's books, not the customer's.

If a TPO provider passes 48E value along at all, it shows up as a lower monthly lease or PPA rate the provider is able to offer, priced in by that company's own finance team. It does not show up as a line item on the homeowner's tax return, a rebate check, or a form to file. Reps should not quote a specific dollar figure for what 48E is "worth" to a given homeowner, because that number is set by the provider's own pricing decisions and varies by provider and by deal, not by a published national table.
What a Cash or Loan Buyer Should Be Told
Plainly: zero federal credit in 2026, under either Section 25D or Section 48E, because a cash or loan buyer owns the system outright and is not the party either credit is written for. A rep telling a cash buyer they will "get the credit" in 2026 is giving that homeowner information that is not accurate, and it is the kind of claim that erodes trust fast once a homeowner's accountant tells them otherwise.
A Script for Explaining 48E Without Overpromising
- Ask financing intent first: cash, loan, or open to a lease or PPA.
- For cash or loan buyers, state plainly that no federal credit applies to a 2026 installation under current law.
- For homeowners open to TPO, explain that the provider, not the homeowner, is the party claiming 48E, and that any resulting savings show up in the rate offered, not a separate rebate.
- Refer the homeowner to the specific TPO provider's own documentation for exact figures rather than quoting a number the rep does not control.
What this means for you
- 25D and 48E are not interchangeable versions of the same credit. 25D belonged to a homeowner who owned their system. 48E belongs to whoever owns the system, which under TPO is the lease or PPA provider.
- A rep cannot accurately quote a specific dollar figure for what 48E is worth to a homeowner, because that number is set by the TPO provider's own pricing, not published nationally.
- Cash and loan buyers get zero federal credit in 2026 under either section, full stop. Do not imply otherwise on a sales call.
