Federal Solar Tax Credit Guide: Claim 30% (2026)
Last updated: February 1, 2026
Complete guide to the 30% federal solar investment tax credit. Eligibility requirements, how to claim it, and what expenses qualify.
The 30% federal solar tax credit is the single biggest incentive for going solar — but it's not the only one. Depending on where you live, state credits, rebates, and renewable energy certificates can stack up to cut your total cost by 40-60%. Missing an incentive you qualify for is like leaving money on the table.
The federal solar Investment Tax Credit (ITC) allows you to deduct 30% of your total solar system cost from your federal income taxes. Under the Inflation Reduction Act, this 30% rate is locked in through 2032, then steps down to 26% (2033) and 22% (2034). There is no cap on the credit amount. For a $25,000 system, the credit is $7,500, directly reducing your tax bill.

Frequently Asked Questions
How do I claim the solar tax credit?
File IRS Form 5695 (Residential Energy Credits) with your annual tax return. Enter the total cost of your solar system, calculate 30%, and transfer the credit to Form 1040. You need a tax liability (owe taxes) to use the credit, but unused amounts carry forward to future years.
What expenses qualify for the 30% credit?
The credit covers: solar panels, inverters, battery storage, mounting/racking hardware, wiring, electrical upgrades required for solar, installation labor, permitting fees, and sales tax on equipment. It does NOT cover roof repairs, tree removal, or landscaping.
Can I claim the credit if I finance my solar system?
Yes, if you own the system (cash purchase or solar loan). The 30% credit applies to the full system cost regardless of how you pay. Solar leases and PPAs do not qualify because the leasing company owns the system and claims the credit themselves.
