Featured Snippet Summary
You can claim the 30% Federal Solar Tax Credit (Residential Clean Energy Credit) by filing IRS Form 5695 along with your standard Form 1040 federal tax return. It applies to solar panels, installation labor, and battery storage.
The Federal Solar Tax Credit (Section 25D) is the most powerful incentive for residential solar panel installation. It allows you to deduct 30% of the entire project cost directly from your federal tax liability. It is a dollar-for-dollar tax reduction, not a rebate.
Eligibility Rules
- Ownership: You must own the system (cash or solar loan). Leased systems or PPAs are not eligible.
- Tax Liability: You must have tax liability to claim the credit. However, if your tax liability is lower than the credit, the remaining value rolls over to future years.
- Equipment: The credit covers solar panels, mounting racks, inverters, wiring, sales tax, and battery storage.
