Federal Solar Tax Credit: What Homeowners Need to Know

Update: The federal 30% Solar Investment Tax Credit (ITC) for residential solar is no longer available. The One Big Beautiful Bill Act signed July 4, 2025 eliminated the residential solar tax credit effective January 1, 2026. Check current federal incentives at energy.gov.

The federal Solar Investment Tax Credit (ITC) was previously the single largest solar incentive available to U.S. homeowners. While the federal credit is no longer available, solar remains a strong investment thanks to falling prices and state-level incentives.

What Was the Solar Tax Credit?

The ITC allowed homeowners to deduct 30% of their total solar system cost from federal income taxes. This was a credit, not a deduction, meaning it directly reduced the tax bill dollar-for-dollar.

Key Facts:

• The 30% federal residential solar credit has expired
• Check energy.gov for any current federal incentive programs
• State and local incentives may still be available
• Source: One Big Beautiful Bill Act

• IRS Form W-9 from installer

Example Calculation

Your Solar Installation:

• System cost: $25,000
• Installation: $3,000
• Electrical upgrades: $1,500
• Sales tax: $1,750

Common Questions

Q: What if I don't owe $9,375 in taxes this year?

A: The credit rolls over to subsequent years. If you owe $5,000 in 2024, you claim $5,000 now and $4,375 in 2025.

Q: Can I claim the credit on multiple properties?

A: Yes, as long as you own and live in each property for part of the year (primary or secondary residence).

Frequently Asked Questions

Is the federal solar tax credit still available?

No. The federal 30% residential solar tax credit expired on December 31, 2025. If you installed a system before that date, you may still be able to claim the credit on your tax return for the year the system became operational. Consult a tax professional for guidance. Schedule your free assessment to explore current incentives.

What happens if I don't owe enough taxes to use the full credit?

The credit rolls over to subsequent years until fully utilized. If you owe $5,000 in 2025 taxes but have a $9,000 credit, you claim $5,000 in 2025 and $4,000 in 2026. There's no time limit on rollovers.

Do state rebates interact with federal incentives?

State and federal incentives are typically independent of each other, allowing you to benefit from both when available. Check your state's current incentive programs for details.

Can I claim any credits for a DIY solar installation?

Check energy.gov for current federal programs. State-level incentives may still be available for DIY installations, though professional installation ensures optimal performance and may be required for warranties. Compare options with Prosper Shield.

Does any credit apply to batteries installed without solar?
