Few solar topics generate more confusion right now than the federal solar tax credit in 2026. Headlines said it was ending, sales pitches say it still exists, and both are partly right, which helps nobody. This guide answers the questions homeowners are actually asking: what changed, whether the federal tax credit is really gone, who can still benefit, what a 2025 installation can still claim, and what takes the credit’s place from here. Plain language, current rules, and no tax jargon beyond what one afternoon with Form 5695 requires.
Key takeaways
- The 30% federal solar tax credit (Section 25D) ended for purchased systems placed in service after December 31, 2025. For 2026 buyers, the federal credit is $0.
- Systems installed and operational by December 31, 2025 still claim the full 30% on the 2025 federal return, using Form 5695.
- A federal credit survives for leased and PPA systems: the provider claims the commercial credit (Section 48E) and may price some of it into your rate.
- State incentives continue and are now the main event: New York pays a 25% state credit, New Jersey pays 15 years of SREC-II income, and programs vary enormously by state.
- Any 2026 quote for a purchased system that lists a federal credit as a line item is wrong, and worth treating as a red flag.
- Solar can still pencil in 2026; the math now runs on per-watt price, utility crediting and state programs rather than a federal discount.
What Is the Federal Solar Tax Credit?
The federal solar tax credit, formally the Residential Clean Energy Credit under Section 25D, let homeowners subtract 30% of a purchased solar system’s cost from their federal income tax. A credit, not a deduction or a rebate: it reduced tax owed dollar-for-dollar, rather than reducing taxable income or arriving as cash at purchase. On a $21,000 system it was worth $6,300, which is why it anchored two decades of solar payback math.
Mechanism | How It Works | When You Get It |
|---|---|---|
Tax credit | Reduces the tax you owe, dollar for dollar | When you file your return |
Tax deduction | Reduces your taxable income; worth your marginal rate | When you file your return |
Rebate | Cash or a price reduction from a state, utility or manufacturer | At or shortly after purchase |
What Changed for the Federal Solar Tax Credit in 2026?
One law changed everything. The credit was scheduled to run through 2032 under the Inflation Reduction Act; the One Big Beautiful Bill Act, signed July 4, 2025, moved the end date up by seven years. Section 25D now applies only to systems placed in service by December 31, 2025, with no phase-down and no partial credit for later installs. The confusion online comes from articles written before that law, still describing a 2032 timeline that no longer exists.
A quick timeline of how it ended: 2005, the credit is created; 2022, the IRA extends 30% through 2032; July 4, 2025, the OBBBA sets the December 31, 2025 termination; January 1, 2026, purchased systems no longer qualify. The same law ended the neighboring Section 25C home-efficiency credits (heat pumps, insulation, windows) on the same date, so any 2026 quote for home energy work that lists federal credits is out of date.
Is the Solar Tax Credit Going Away?
For buyers, it is not going away; it is gone. There is no step-down schedule, no grace period, and no announced replacement for purchased residential systems. That is the plain answer, and it is worth stating bluntly because sales scripts move slower than tax law: through 2026 you should expect to hear the 30% quoted as if nothing happened, sometimes from confusion and sometimes on purpose. A purchase quote listing a federal credit is wrong on its face, and wrong in a way that inflates the savings story; our solar scams guide covers that red flag and its four siblings.
What is NOT gone: the commercial credit behind leases and PPAs, every state-level program, and your ability to claim a 2025 install on your 2025 return. Those three survivors are the rest of this guide.
Who Qualifies for a Federal Solar Credit in 2026?
Directly: only companies. The commercial clean-electricity credit, Section 48E, survived, and when a company owns the panels on your roof and sells you the power through a lease or power purchase agreement, that company can claim the credit, generally for projects that began construction before July 4, 2026, or that are placed in service before January 1, 2028.
Indirectly, that can still mean you. A lease or PPA in 2026 can be priced with federal money behind it, and a competitive provider should pass some of that through as a lower rate. The pass-through is not automatic or visible, so compare the offered rate against your utility’s price and against an owned-system quote before treating the embedded credit as your savings. Our free solar panels guide explains these third-party arrangements, including the fine print that matters more than the subsidy behind them.
Pricing a system without the federal credit?

The credit was worth 30% of the total qualified cost: equipment, labor, permitting, and sales tax where charged. A $21,000 system carried $6,300; a $30,000 system with a battery, $9,000. If your system was installed and operational by December 31, 2025, that math still applies to you, on the federal return you file for tax year 2025. The credit is nonrefundable, offsetting tax you owe rather than generating a refund on its own, and unused amounts carry forward to future years.
How to Claim a 2025 Install on Your Return
Three steps, in order. First, gather the paperwork that proves cost and timing: the signed contract, final paid invoices, and your utility’s permission-to-operate letter, the cleanest evidence of the in-service date. Second, complete Form 5695, Residential Clean Energy Credit, entering the total qualified cost; the form computes the 30%. Third, carry the result to Schedule 3 of your Form 1040.
Two cautions worth an accountant’s hour: financed systems claim the contract price, not the sum of loan payments, and dealer fees buried in solar loans do not always qualify. Roof work bundled into a solar contract is claimable only where it is part of the solar installation itself, a line the IRS reads narrowly. The phrase that decides everything is placed in service: installed and capable of operating by the deadline, not merely signed for. If a late-2025 signature came with a 2026 install, talk to a tax professional before filing.
What Expenses Were Covered Under the Solar Energy Credit?
| Typically Included | Typically Not Included |
|---|---|
| Panels, inverters, racking and wiring | Roof replacement or repairs not part of the solar work |
| Labor for on-site preparation, assembly and installation | Extended warranties and service plans |
| Battery storage (3 kWh or larger) | Loan interest and some dealer financing fees |
| Permitting fees, inspection costs and sales tax | Tree removal for sun exposure |
What Replaces the Credit: Your State
With the federal layer gone for buyers, the incentive map is now 50 different maps, and the gap between a strong state and a weak one is wider than the old federal credit ever was. New York still pays a 25% state tax credit of up to $5,000, and it applies to leases and PPAs of ten years or longer, not just purchases. New Jersey pays performance income instead: 15 years of SREC-II certificates at $76.50 each, on top of full retail net metering. Massachusetts runs performance payments through SMART 3.0, Washington, D.C.’s certificate market pays a typical system roughly $3,000 a year, New Mexico offers a 10% state credit up to $6,000, and Delaware pays $0.70 per watt in grants, while other states offer essentially nothing beyond net metering.
Before any 2026 quote conversation, read your own state’s page in our solar incentives guide: what exists, what it pays, and who does not qualify. The absence of the federal credit makes those local programs the whole incentive story.
Why 2026 May Still Be a Good Time to Go Solar
Losing 30% off the top stretches every purchased-system payback, but it did not change the two forces that were always doing most of the work: what you pay per watt, and what electricity costs where you live. Rates keep rising, and every increase shortens real-world payback. A fairly priced system in a strong-crediting state still pays back on reasonable timelines; the strongest markets never depended on the federal credit alone.
The practical 2026 playbook: compare at least three quotes on per-watt price against our state benchmarks, verify how your utility credits exported power, check your state’s programs, and treat any projection that cannot name your utility’s actual export rate as marketing. Where the math works best right now is ranked, with the reasoning shown, in our best states for solar guide.
The 2026 Rules in One Paragraph, and Your Next Step
The federal solar tax credit is over for buyers, alive for 2025 installs at filing time, and embedded in lease pricing where providers choose to share it. States now carry the incentive story, and they carry it unevenly. If you are weighing solar in 2026, the decision runs on your numbers, your rates, your roof, your state’s programs, not on a federal discount that no longer exists, and honest math is the whole game.

Can I claim the federal solar tax credit if I financed my system?
For a 2025 installation, yes: financing does not disqualify you as long as you own the system rather than lease it. You claim 30% of the contract price, not the sum of your loan payments, and dealer fees buried in the loan do not always qualify. For systems installed in 2026, there is no federal credit to claim regardless of how you paid.
Do solar leases qualify for the federal tax credit?
Not for you: in a lease or PPA the provider owns the system and claims the commercial credit under Section 48E. A competitive provider should price some of that value into your rate, but nothing requires it, so evaluate the rate itself rather than the subsidy behind it.
Can I carry over unused solar tax credit amounts?
Yes. The credit is nonrefundable, so it offsets tax you owe rather than paying out cash, and any unused portion from a 2025 claim carries forward to future returns. Confirm the mechanics for your situation with a tax professional.
Does a battery qualify for the federal solar tax credit in 2026?
Batteries followed the same rules as panels: storage of 3 kWh or more qualified under Section 25D through 2025 and does not qualify for purchases in 2026. A battery in a leased system rides on the provider’s commercial credit like the rest of the equipment.
Can state incentives be combined with what remains of the federal credit?
State programs run under state law and continue regardless of the federal change: they stack with a 2025 federal claim and stand alone for 2026 installs. New York’s 25% credit even applies to long-term leases, so check your state’s rules before assuming anything.
