What is the solar tax credit percentage in 2026?

The Residential Clean Energy Credit is 30% of the total cost of your solar panel system in 2026, including installation labor. There is no cap on the credit amount. A $25,000 system earns a $7,500 credit. The 30% rate is locked in through 2032, then drops to 26% in 2033 and 22% in 2034.

Can I claim the solar tax credit if I don't owe that much in taxes?

Yes. If the credit exceeds your tax liability for the year, the unused portion carries forward to future tax years. You cannot receive it as a refund — it can only offset taxes owed. Example: $6,000 credit, $3,500 tax liability this year. You claim $3,500 now and carry $2,500 forward to next year.

Do I need to own my home to claim the solar tax credit?

You must own the solar system, but you don't have to own the home. If you own a solar system on a rented home you live in, you can still claim the credit. However, if you lease your solar panels or enter a power purchase agreement (PPA), the leasing company — not you — owns the panels and claims the credit.

What does the solar tax credit cover?

The credit covers the full cost of the solar panel system, including equipment, labor, wiring, permits, and inspection fees. It also covers battery storage systems (without the solar requirement since 2023), solar water heaters, geothermal heat pumps, fuel cells, and small wind energy systems installed on your primary or secondary home.

Is the solar tax credit the same as a solar tax deduction?

No. A tax credit reduces your tax bill dollar for dollar. A deduction only reduces your taxable income. A $6,000 tax credit saves you exactly $6,000. A $6,000 deduction at a 22% tax rate would save you only $1,320. The solar credit is far more valuable than a deduction.

Does the solar tax credit affect my state taxes?

The federal solar tax credit (Form 5695) has no direct effect on your state taxes. Many states also offer their own solar incentives — rebates, tax credits, or property tax exemptions — that can be claimed on top of the federal credit. Check your state energy office for current programs.

Solar Tax Credit 2026: Claim 30% Back on Solar Panels (IRS Form 5695)

The federal solar tax credit — officially the Residential Clean Energy Credit — gives you back 30% of the total cost of your solar panel installation as a direct credit against your federal income taxes. There is no income limit and no cap on the credit amount. The 30% rate is guaranteed through 2032. On a typical $20,000 home solar system, that is a $6,000 tax credit.

Solar Tax Credit Rates by Year

Year	Credit rate	Action
2022–2032	30%	Claim on Form 5695
2033	26%	Rate drops
2034	22%	Rate drops again
2035 and after	0%	Credit expires (residential)

If you are considering solar, 2026 is an optimal year to act — you lock in 30% and have years of carry-forward available if your credit exceeds your annual tax liability.

How Much Is the Credit Worth?

System cost	30% credit
$10,000	$3,000
$15,000	$4,500
$20,000	$6,000
$25,000	$7,500
$30,000	$9,000
$40,000	$12,000

The average residential solar installation costs between $15,000 and $25,000 before incentives, putting the typical credit in the $4,500–$7,500 range.

What Qualifies for the Credit

The Residential Clean Energy Credit covers:

Eligible item	Notes
Solar photovoltaic (PV) panels	Main panels that generate electricity
Solar water heaters	Must meet federal efficiency requirements
Battery storage systems	Qualifies on its own since August 2022 — no solar required
Geothermal heat pumps	Must meet Energy Star requirements
Fuel cells	$500 credit cap per 0.5 kW of capacity
Small wind turbines	Must be on a home you own
Installation labor	Wiring, inverters, mounting, permits, inspections

What does NOT qualify:

Swimming pool or hot tub solar heating systems
Solar-powered outdoor lighting
Portable solar generators
Panels on properties used purely for business (a separate business credit applies)
Leased solar systems (the leasing company claims the credit, not you)

Who Can Claim the Credit

You qualify if:

You own the solar system. Leased panels or power purchase agreements (PPAs) do not qualify — the leasing company owns the equipment and takes the credit.
The system is at your primary or secondary home. Rental properties do not qualify for the residential credit (a commercial credit exists for rental and business properties).
The system is new or being used for the first time. You cannot claim the credit on a used system purchased from another homeowner.
The home is in the United States.

Note: You do not need to own the home. You can claim the credit on a solar system you own even if you rent the property where it is installed, as long as you live there.

How to Claim the Solar Tax Credit

Step 1: Get a detailed invoice from your installer. Document every line item — panels, inverter, labor, permits. The credit applies to the total eligible cost.

Step 2: Complete IRS Form 5695. This is the “Residential Energy Credits” form. Part I covers the Residential Clean Energy Credit (solar). The math is straightforward: multiply your eligible costs by 30%.

Step 3: Enter the credit on Schedule 3. The credit from Form 5695 flows to Schedule 3 (Additional Credits and Payments), which reduces your total tax liability on Form 1040.

Step 4: Carry forward unused credit. If the credit exceeds your tax liability for 2026, the unused amount automatically carries forward to 2027 and beyond until fully used.

Worked Example: $22,000 Solar System

Item	Amount
Total installation cost	$22,000
Solar tax credit (30%)	$6,600
Your 2026 federal tax liability	$4,200
Credit applied this year	$4,200
Credit carried forward to 2027	$2,400

You eliminate your entire 2026 tax bill and carry $2,400 into next year.

Interaction With State Incentives

The federal solar tax credit stacks on top of state programs. Common additional incentives:

State	Available incentive
California	No state credit, but property tax exclusion on added home value
New York	25% state credit (up to $5,000) in addition to federal
Massachusetts	15% state credit (up to $1,000) + sales tax exemption
Texas	No state income tax, but many utilities offer rebates
New Jersey	Solar Renewable Energy Certificates (SRECs)
Maryland	$1,000 state grant through 2026

Check your state’s energy office or the Database of State Incentives for Renewables & Efficiency (DSIRE) at dsireusa.org for current programs.

Does the Solar Credit Affect My Home’s Value or Property Taxes?

Adding solar typically increases your home’s resale value. Many states — including California, Florida, Arizona, and New York — exempt solar installations from property tax assessments, meaning you do not pay higher property taxes on the added value. Check your state’s specific rules.

The federal tax credit itself does not affect your home’s cost basis for capital gains purposes. However, any depreciation or commercial credit claimed on a rental property would reduce your basis.

Battery Storage Without Solar

Since August 16, 2022, standalone battery storage systems (such as the Tesla Powerwall) qualify for the 30% credit without requiring solar panels. The battery must:

Have a capacity of at least 3 kilowatt-hours
Be installed at a home you own or live in

This is a significant change that makes battery backup systems eligible even for homeowners who already have solar installed and just want to add storage.

Frequently Asked Questions

Can I claim the credit on a vacation home? Yes. The credit applies to both your primary and secondary residence.

Can I claim it more than once? Yes, if you install qualifying systems in different tax years you can claim the credit each time — for example, solar panels one year and a battery system the next.

What if I sell my home before using all the credit? Unused carry-forward credits stay with you, not the home. You can continue using them against your taxes in future years even after selling.
