Solar Federal Tax Credit 2026

Update (2026): The federal Residential Clean Energy Credit (Section 25D) expired December 31, 2025, following the passage of the One Big Beautiful Bill Act (OBBBA). The information below reflects historical credit availability. Check state and local programs for current incentives.

With residential electricity prices increasing by over 13% since 2021, homeowners are facing unprecedented utility costs. The federal government offers a direct answer to this financial pressure through tax incentives designed to lower the cost of energy independence. So for installations completed in 2026, this credit remains a primary tool for reducing the $20,000 average upfront cost of a residential solar panel system.

What is the Federal Solar Tax Credit in 2026, and how much can I save?

The Residential Clean Energy Credit is a federal tax incentive that offers a 30% credit on the total cost of a new solar energy system installed in 2026. This credit directly reduces a homeowner's federal tax liability dollar-for-dollar, with no annual cap on the total amount claimed.

The federal solar tax credit, officially named the Residential Clean Energy Credit under the Inflation Reduction Act, provides a 30% credit for qualified solar electric property expenditures. And this credit applies to the total cost of the system, including panels, inverters, mounting equipment, labor for on-site preparation and installation, and even battery storage systems with a capacity of 3 kilowatt-hours (kWh) or greater. So for a system costing $25,000, the credit provides a $7,500 reduction in federal taxes owed. But the credit is nonrefundable, meaning it can't reduce your tax liability below zero. Any unused portion of the credit, however, can be carried forward to future tax years. Homeowners can use our free rebate calculator to estimate their specific savings.

What Solar Equipment Qualifies for the 2026 Tax Credit, and are there Income Limits?

Qualified solar equipment for the 2026 tax credit includes photovoltaic (PV) cells, panels, inverters, wiring, and mounting hardware. And crucially, battery storage technology with a capacity of 3 kWh or more also qualifies. So there are no income limits to claim this federal credit.

To qualify for the 30% credit in 2026, the solar equipment must be new and used for the first time. The credit only applies to systems placed in service at a primary or secondary residence located in the United States. And this includes not just solar panels but also the balance-of-system equipment essential for operation. So items like power conditioning equipment and transfer switches are covered. The inclusion of battery storage is a key update from the Inflation Reduction Act, allowing homeowners to store excess solar energy for use during outages or peak-demand hours. Unlike some other energy tax credits, the Residential Clean Energy Credit has no income restrictions, making it accessible to a wider range of taxpayers.

"The credit applies to the cost of new, qualified clean energy property for your home. This includes costs for solar, wind, geothermal, and fuel cell property." — IRS.gov

How Do I Claim the 2026 Federal Solar Tax Credit, and What Forms Are Needed?

To claim the 2026 federal solar tax credit, homeowners file IRS Form 5695, Residential Energy Credits, with their annual federal tax return. This form calculates the total credit amount based on eligible expenses. So the final credit amount is then entered on Schedule 3 (Form 1040).

Claiming the credit is a straightforward part of the annual tax filing process. But you must have proof of purchase and installation, including contracts and receipts that detail the total gross cost of the system. So it's essential to keep all documentation from your solar installer. The installation must be complete and the system "placed in service" during the 2026 tax year to be claimed on the taxes you file in early 2027. And if your tax liability is less than the credit amount, the remaining credit can be carried forward. For example, if your credit is $7,500 but your tax liability is only $5,000, you can use the remaining $2,500 in the following tax year. This carryforward provision ensures you receive the full value of the credit over time.

When Did the Federal Solar Tax Credit Program Start, and What's its Status in 2026?

The federal solar tax credit program, originally established by the Energy Policy Act of 2005, has been extended and modified multiple times. Its current iteration, the Residential Clean Energy Credit, was established by the 2022 Inflation Reduction Act and is set at 30% for systems installed in 2026.

The program's journey began with a 30% credit, which was later scheduled to phase out. But the Inflation Reduction Act of 2022 revitalized the incentive, restoring the 30% rate and extending it through December 31, 2025 for qualifying installations. So homeowners planning projects for 2026 can proceed with confidence that the 30% credit will be available. After December 31, 2025, the credit is scheduled to step down to 26% for systems installed in 2033 and 22.5% for systems installed in 2034. And the credit is set to expire entirely after December 31, 2025, unless Congress extends it again. This long-term schedule provides a clear roadmap for homeowners considering investments in solar panel rebates and installations.

Can I Combine the 2026 Federal Solar Tax Credit with Other State or Local Incentives?

Yes, homeowners can combine the 30% federal solar (available through 2032 under current IRA provisions) tax credit with state, local, and utility-level incentives in 2026. However, any rebate received from a utility company is typically subtracted from the total system cost before calculating the federal credit amount, which reduces the federal credit value. (Note: Federal tax credit percentages and availability are subject to change; the 30% Residential Clean Energy Credit under Section 25D expired December 31, 2025. Verify current incentives at energy.gov.)

Stacking incentives is a common strategy for maximizing savings. So homeowners should research local programs, which vary widely. For example, a state tax credit is generally stackable without reducing the federal credit base. But a direct rebate from your utility company is considered a price reduction.

"State energy-efficiency incentives are generally not included in your federal gross income. However, a utility rebate for buying an energy-efficient appliance is sometimes subtracted from the cost basis of the property." — ENERGY STAR

So if a $30,000 solar system receives a $2,000 utility rebate, the federal tax credit calculation is based on a cost of $28,000. This results in a federal credit of $8,400 (30% of $28,000) instead of $9,000. This rule prevents "double-dipping" on the same portion of the cost. Other incentives like heat pump rebates operate under different rules.

What are the eligibility requirements for the federal solar tax credit in 2026?

To be eligible, you must own your home (it can't be a rental property you don't live in) and the solar PV system must be new or used for the first time. The system must be placed in service during the 2026 calendar year at your primary or secondary U.S. residence. There are no income limits to qualify for this credit.

What percentage is the federal solar tax credit for systems installed in 2026?

For any qualifying solar energy system placed in service between 2022 and December 31, 2025, the federal tax credit is 30% of the total project cost. This includes all equipment, labor, and permitting fees. So a system installed in 2026 is eligible for the full 30% credit amount with no dollar cap.

How do I claim the federal solar tax credit for a 2026 solar (available through 2032 under current IRA provisions) installation?

You claim the credit when you file your 2026 federal income taxes in early 2027. Homeowners must complete and attach IRS Form 5695, Residential Energy Credits, to their Form 1040. You will need your receipts and documentation from the solar installer to accurately report the total system cost on the form.
