The federal solar tax credit is 30% in 2026. No application. No lottery. Just a dollar-for-dollar reduction off your federal tax bill — one of the cleanest financial arguments for going solar in the entire US tax code, and it's sitting there for any homeowner willing to act on it.
- The credit is 30% of your total system cost — no dollar cap, no income limit.
- Panels, batteries, labor, and permits all qualify — roof repairs do not.
- You claim it on IRS Form 5695, then carry it to your Form 1040.
- Stack it with state incentives to cut your payback period to 6–8 years.
- The 30% rate holds through 2032 under the Inflation Reduction Act.
What Is the Solar Tax Credit in 2026?
Dollar-for-dollar. That phrase is worth slowing down for. If your credit is $8,400, your tax bill drops by $8,400 — not your taxable income. Your actual bill. It's not a deduction. Not a rebate. A direct subtraction from what you owe the IRS.
The credit applies to both residential and commercial solar installations on US property. Your primary residence qualifies. So does a second home — as long as you own the system outright. The 30% rate is locked in through 2032 under the Inflation Reduction Act, then steps down to 26% in 2033 and 22% in 2034 before expiring for residential.
What Qualifies for the 30% ITC?
The credit covers your total installed cost — not just the panels. That number adds up faster than most people expect.
Before the credit kicks in, you need to know what you're actually spending. Our solar panel installation cost by state guide breaks down every line item.
- Solar panels and modules
- Inverters (string, micro, hybrid)
- Battery storage (4+ kWh capacity)
- Labor and installation costs
- Permitting and inspection fees
- Wiring and electrical upgrades tied to the system
- Mounting hardware and racking
- Sales tax on all of the above
- Roof repairs or replacement
- Utility interconnection fees
- Extended warranties or maintenance plans
- Leased systems or PPAs (you must own the panels)
- Used or refurbished equipment
The lease/PPA trap catches a lot of buyers. Sign a power purchase agreement and the installer owns the panels — which means they claim the ITC, not you. Ownership is the only variable that matters here.
How to Claim It: IRS Form 5695 (Step-by-Step)
No separate registration. No special application. You claim the credit when you file your annual federal tax return for the year the system was placed in service — meaning operational, not just purchased or contracted.
-
1
Get your installer's final invoice. The total amount paid — panels, labor, permits, equipment — is your credit basis. Keep this document. The IRS may ask for it.
-
2
Calculate 30% of your total system cost. A $28,000 system yields an $8,400 credit. A $35,000 system with battery yields $10,500. The math is simple. The savings are not small.
-
3
Complete IRS Form 5695, Part I (Residential Energy Credits). Line 1 is your total qualified costs. Line 6 calculates 30%. Any reputable tax software walks you through this automatically.
-
4
Transfer the credit to Schedule 3, Line 5 of your Form 1040. This is where it actually reduces your tax liability. Software handles the transfer — you confirm the number.
-
5
Carry forward any unused credit. Tax liability of $5,000 but a credit of $8,400? Apply $5,000 this year, roll $3,400 to next year's return. Not a dollar is lost.
You can carry the unused credit forward indefinitely — it doesn't expire. Even if you owe little to no taxes this year, you won't lose a dollar of your ITC.
Maximize Your Savings: Stack With State Incentives
The federal ITC stacks on top of state rebates, utility incentives, and local programs. The combination can be dramatic. But the order of operations matters.
"Most homeowners recover their full installation cost within 6–8 years when combining the ITC with state incentives — and that's before accounting for rising electricity rates."
If your state provides a $3,000 rebate on a $30,000 system, your federal credit basis may drop to $27,000 — yielding an $8,100 ITC instead of $9,000. The rules hinge on whether the rebate flows from a utility or a state program. Confirm the specifics with your tax advisor. Either way, you come out substantially ahead.
Consider a couple in Arizona who paired the 30% federal ITC with a $2,500 state tax credit and a $500 utility rebate. Their $32,000 system came in under $20,000 after all incentives. Payback: under 7 years.

The 30% federal ITC is the single most powerful incentive available to solar buyers in 2026. Claim it on Form 5695, carry forward anything unused, and stack it with your state's programs. A $30,000 system can realistically cost under $18,000 after all incentives — and the credit drops to 26% in 2033. The clock is slow, but it is ticking.
Frequently Asked Questions
Is the solar tax credit still 30% in 2026?
Yes. The Inflation Reduction Act locked the federal solar ITC at 30% through 2032. It drops to 26% in 2033 and 22% in 2034 before expiring for residential installations. The 30% window has years left — but it won't last forever.
What if my tax liability is less than my solar credit?
Carry the unused portion forward to the following tax year. There is no limit on how many years you can roll it — you won't lose the credit. If you pay little in federal taxes, it may take a few years to fully absorb it. That's fine.
Does battery storage qualify for the 30% ITC in 2026?
Yes. As of 2023, standalone battery storage with at least 4 kWh of capacity qualifies for the full 30% ITC — no solar panels required. You don't need to install both together to claim the credit on storage.
Can I claim the ITC if I finance my solar system with a loan?
Yes. Own the system — financed or paid in full — and you qualify. The credit is based on total installed cost, not how much you've paid out of pocket at the time of installation.

- Leased systems don't qualify. You must own the panels to claim the ITC.
The math on solar has never been cleaner. Between the 30% federal credit, rising utility rates, and battery storage now qualifying on its own, the case for going solar in 2026 is stronger than any prior year. Run your numbers, claim what you're owed, and let the sun start paying your energy bills.
