Federal Solar Tax Credit Guide - How to Claim the 30% ITC
The federal solar investment tax credit (ITC) lets you deduct 30% of the cost of a solar energy system from your federal taxes. For a $20,000 solar installation, that is a $6,000 tax credit - real money back in your pocket. This guide explains how to claim it in 2026.
How the Federal Solar Tax Credit Works
The ITC is a dollar-for-dollar reduction in your federal income tax. If you owe $8,000 in taxes and claim a $6,000 solar credit, you only pay $2,000. It is not a deduction - it is a direct credit, making it one of the most valuable incentives available.
- 2022-2032 - 30% tax credit
- 2033 - 26% tax credit
- 2034 - 22% tax credit
- 2035 and beyond - Credit expires for residential installations (unless renewed by Congress)
Who Qualifies for the Solar Tax Credit?
You qualify if you meet these requirements:
- You own the solar energy system (leased systems do not qualify)
- The system is installed at your primary or secondary residence in the U.S.
- The system was placed in service during the tax year you are claiming
- You have enough federal tax liability to use the credit (or can roll it forward)

How to Claim the Solar Tax Credit
Follow these steps when filing your taxes:
- Step 1 - Get IRS Form 5695 (Residential Energy Credits)
- Step 2 - Enter the total cost of your solar system on Line 1
- Step 3 - Calculate 30% of the total cost
- Step 4 - Transfer the credit amount to your Form 1040
Keep all receipts, contracts, and proof of payment. Your installer should provide documentation of the total system cost including equipment, labor, and permitting.
Common Mistakes to Avoid
The most frequent errors include claiming the credit on a leased system, forgetting to include installation labor in the total cost, and not carrying forward unused credits. If your tax liability is less than the credit amount, you can carry the remaining balance forward to next year.

Frequently Asked Questions
Can I claim the solar tax credit if I lease my panels?
No. The solar tax credit is only available to system owners. If you lease panels or sign a power purchase agreement (PPA), the leasing company claims the credit instead.
What if my tax bill is less than the solar credit amount?
You can carry the unused portion of the credit forward to the following tax year. For example, if your credit is $6,000 but you only owe $4,000, the remaining $2,000 rolls forward to next year.
Does the solar tax credit apply to battery storage?
Yes, as of 2023 the ITC covers standalone battery storage systems as well as batteries paired with solar panels. The battery must be installed at a qualifying residence.
