Tax incentives are one of the most compelling reasons to go solar in 2026. The federal government and many states offer significant credits and deductions that can cut your total cost by 30–50% or more. Here’s exactly what’s available and how to claim it.
The Federal Solar Tax Credit (ITC)
The Investment Tax Credit (ITC) is the biggest solar incentive available to homeowners. In 2026, it allows you to claim 30% of your total solar system cost as a credit on your federal income taxes.
What’s Covered
The ITC applies to:
- Solar panels
- Inverter(s)
- Battery storage (if charged primarily by solar)
- Wiring and electrical components
- Racking and mounting hardware
- Labor costs for installation
- Permit fees
- Inspection fees
- Sales tax on equipment
If you add a battery storage system at the same time as solar (or within the same tax year), the battery is included in the credit calculation. Batteries added in later years without panels can still qualify for the 30% credit on their own under current law.
How It Works
It’s a tax credit, not a tax deduction. A deduction reduces your taxable income. A credit directly reduces what you owe the IRS dollar-for-dollar.
Example:
- System cost: $22,000
- 30% credit: $6,600
- If you owe $8,000 in federal taxes, your liability drops to $1,400
If your credit exceeds your tax liability in year one, the remainder rolls over to the following tax year. You can continue to roll it over until it’s fully used.
Important: You must have sufficient federal tax liability to benefit from this credit. If you owe little or nothing in federal taxes (common for retirees or very low-income households), the credit may not fully help you. Consult a tax professional.
Current Schedule
The 30% rate is locked in through 2032. After that:
- 2033: 26%
- 2034: 22%
- 2035: Expires for residential (unless Congress extends it)
There’s no urgency to rush — you have several years — but incentive policy can change.
How to Claim It
File IRS Form 5695 with your annual tax return. Your solar installer will typically provide documentation of your system cost. Keep all receipts and contracts.

Beyond the federal credit, many states offer their own incentives. Here are some notable programs in 2026:

Utility Rebates
Many utility companies offer one-time rebates for solar installation. These vary by utility and can range from $100 to several thousand dollars. Some utilities have limited program funds that run out early in the year.
Ask your installer if they know of rebates available through your specific utility.
The Inflation Reduction Act: Additional Credits
The Inflation Reduction Act (IRA) of 2022 added several extra incentive layers for qualifying homeowners:
Low-income bonus: An additional 10–20% credit for households in low-income communities or Indian lands.
Domestic content bonus: Systems using panels and components manufactured in the U.S. may qualify for an extra 10% credit on commercial installations. Residential rules are still evolving — check current guidance.
Energy communities bonus: Homes located in areas with historical fossil fuel employment may qualify for an additional 10% credit.
Can You Combine Incentives?
Yes — you can generally stack federal and state incentives. However, some state programs reduce their benefit if you also receive federal credits. And some utility rebates must be subtracted from your cost before calculating the federal credit.
Work with a tax professional familiar with solar incentives to maximize what you claim.
The Bottom Line
The federal 30% tax credit alone makes solar meaningfully more affordable. Stack state credits, utility rebates, and exemptions on top, and the total incentive package can reduce your effective system cost by 40–60% in favorable states.
Claim it the right way: file Form 5695, document your costs, and consult a tax pro if you’re unsure about your tax liability.
