The solar tax credit changed. Read this before you sign anything.
The 30% federal credit for systems you buy yourself ended for installations after 31 December 2025. If a salesperson is still quoting it, that is the whole conversation.
For more than a decade, the arithmetic of home solar in the United States rested on one number: a federal tax credit worth 30% of the system cost. It shaped every sales pitch and most payback calculations.
That credit — Section 25D of the tax code, the one homeowners claim when they buy a system — ended for systems placed in service after 31 December 2025. The One Big Beautiful Bill Act, signed in July 2025, terminated it outright. No phase-down, no transition period: 30% through the end of 2025, then zero for customer-owned residential systems.
What that actually means for you
| Your situation | Where things stand |
|---|---|
| System installed and operational on or before 31 Dec 2025 | The 30% credit is generally claimable on the relevant tax return. Keep every invoice and the commissioning date. |
| Buying a system now, with cash or a loan | The federal §25D credit is no longer available. Any pitch built on 30% back is built on something that has expired. |
| Lease or PPA (third-party owned) | Different mechanism. The company that owns the equipment may claim the commercial credit (§48E), which has its own timelines and conditions. You are not claiming anything — any benefit reaches you only as a lower rate, if at all. |
| State and utility incentives | Entirely separate and still exist in many states. These did not change with the federal credit, and they are now the main incentive. |
Confirm your own position with a tax professional. "Placed in service" has a specific meaning and it is not always the day the panels went up.
The confusion this created, in homeowners' words
Tax-credit misunderstanding generated complaints long before the law changed — and then the deadline itself generated a fresh set from people whose installations ran late.
- “the "rebate" is actually a tax credit which doesn't apply to me” Homeowner complaint record, AZ
- “Lost 2025 federal tax credit: $5,328” Homeowner complaint record, MD
- “no longer qualify for the tax incentive” Homeowner complaint record, MD
- “service before the end of 2025 so I could qualify” Homeowner complaint record, MD
- “working against a Federal tax credit deadline of 31 Dec 2025” Homeowner complaint record, MD
- “I have not received my government rebates at all. Not even a single mention” Homeowner complaint record, NJ
- “Promised it would be AT LEAST that much” Homeowner complaint record, UT — regarding tax benefit
The first quote is the important one, and it was true even when the credit existed: a tax credit is not a rebate. Nobody sends you a cheque. It reduces what you owe in federal tax — so a household whose tax liability is smaller than the credit could never use all of it in the first place. Retirees on modest fixed incomes were the group most often surprised by this.
Credit, rebate, deduction — they are not the same thing
| Term | What it actually does |
|---|---|
| Tax credit | Reduces the tax you owe, dollar for dollar. Useless beyond your liability unless carry-forward rules apply. No cheque arrives. |
| Rebate | Actual money back, usually from a state programme or utility, often at point of sale. This is the one that behaves like a discount. |
| Deduction | Reduces taxable income, not tax owed. Worth much less than a credit of the same headline size. |
| Performance payment (SREC etc.) | Ongoing payments for the power you generate, where the state runs such a market. Variable and market-priced. |
If a salesperson uses these interchangeably, that alone tells you how carefully the rest of the numbers were prepared.
What to ask now that the federal credit is gone
Before you sign anything in 2026
- Does this quote assume a federal tax credit? Ask directly and get the answer in writing. If the payback maths includes 30% back on a system you are buying, the maths is wrong and every figure downstream of it is wrong too.
- Show me the payback with zero federal credit This is the number that matters now. Some systems still pay back well on state incentives and avoided electricity alone; some never did without the federal credit.
- Which state or utility incentives am I actually eligible for, and who applies? These still exist in many states and are now the main event. One complaint describes a company having state funds "issued directly to them" — know who receives the money and when.
- Am I buying, leasing, or signing a PPA? Get it in one plain sentence. It determines who owns the equipment, who claims any credit, who maintains it, and what happens when you sell the house.
- If this is a lease or PPA, what is the escalator? Many rise by a fixed percentage annually. A rate that beats your utility today can lose to it later — ask for the payment in year one, year ten and year twenty.
- Get every incentive claim in writing, signed A verbal promise about tax treatment is worth nothing and, when it turns out to be wrong, is nearly impossible to prove.
Does solar still make sense without it?
Honestly: sometimes yes, sometimes no, and it depends on inputs that are specific to you rather than on any national rule of thumb. What has changed is that the answer now genuinely has to be calculated rather than assumed.
It leans favourable where electricity is expensive and rising, where the roof faces well and is unshaded, where the state or utility still offers real incentives, and where you plan to stay long enough to reach payback. It leans unfavourable where power is cheap, where export compensation has been cut, where the roof needs replacing within a few years, or where the financing is expensive enough to eat the savings.
Two things worth doing before deciding: get quotes from more than one installer, and ask each to show the payback without any federal credit. If the only version that works requires an expired credit, that is your answer.

Is there still a federal solar tax credit in 2026?
Not for systems homeowners buy themselves. The residential clean energy credit (Section 25D) ended for systems placed in service after 31 December 2025, terminated by the One Big Beautiful Bill Act signed in July 2025 — with no phase-down.
Third-party-owned systems (leases and PPAs) sit under the separate commercial credit (Section 48E), which has its own timelines; any benefit reaches you indirectly as a lower rate. State and utility incentives are unaffected and still exist in many places. Position as of 14 August 2026 — verify with the IRS or a tax professional.
I installed solar in 2025 — can I still claim the credit?
Generally yes, if the system was placed in service on or before 31 December 2025 — the credit is claimed on the tax return for the year the system was placed in service.
Keep the invoices and evidence of the commissioning date, because "placed in service" is not automatically the day the panels went on the roof. Confirm your specific situation with a tax professional.
Is the solar tax credit a rebate?
No, and this was one of the most common misunderstandings even while it existed. A tax credit reduces the federal tax you owe — nobody sends you a cheque.
That means a household whose annual tax liability was smaller than the credit could never use the whole thing. One homeowner complaint puts it exactly: the "rebate" is actually "a tax credit which doesn't apply to me." Retirees on modest fixed incomes were most often caught by this.
Does solar still make financial sense without the federal tax credit?
Sometimes — but it now has to be calculated rather than assumed. It leans favourable with expensive and rising electricity, a well-oriented unshaded roof, meaningful state or utility incentives, and a long enough stay to reach payback.
It leans unfavourable with cheap power, reduced export compensation, a roof needing replacement soon, or expensive financing. Ask every installer for the payback with zero federal credit — if only the version with an expired credit works, that is your answer.
Why are solar companies pushing leases and PPAs now?
Because the commercial credit (Section 48E) can still reach third-party-owned systems on its own timeline, while the homeowner credit is gone. The economics now favour a structure where the company owns the equipment.
That does not make leases wrong — for households with little tax liability they can be sensible. But know which structure you are signing, who owns the hardware, what the annual escalator is, and what happens when you sell the house.
What incentives are left for home solar?
State-level credits and rebates, utility rebates, performance payments such as SRECs where those markets exist, net-metering or export compensation rules, and in some places property-tax or sales-tax exemptions. None of these were changed by the federal termination.
They vary enormously by state and utility, so check your state energy office and your own utility directly rather than relying on a national figure — and confirm who applies for what, and who receives the money.
