Federal Solar Tax Credit 2025: Claim Your 30% ITC Before Dec 31 Deadline

⚠️ CRITICAL DEADLINE: The federal Solar Investment Tax Credit expires December 31, 2025. The One Big Beautiful Bill Act signed July 4, 2025 eliminated the residential solar tax credit effective January 1, 2026. Systems must be operational by year-end to qualify for this $5,000-$10,000 incentive.

The federal Solar Investment Tax Credit (ITC) is the single largest solar incentive available to U.S. homeowners, worth an average of $5,000-$10,000 on typical residential installations. With only weeks remaining before the deadline, understanding how to claim this credit is critical for maximizing your solar investment.

What is the Solar Tax Credit?

The ITC allows you to deduct 30% of your total solar system cost from your federal income taxes. This is a credit, not a deduction, meaning it directly reduces your tax bill dollar-for-dollar.

Key Facts:

• 30% credit for systems operational by December 31, 2025
• 0% credit starting January 1, 2026 (eliminated by OBBB Act)
• No cap on credit amount
• No income restrictions
• Applies to solar panels AND battery storage

Example Calculation

Your Solar Installation:

• System cost: $25,000
• Installation: $3,000
• Electrical upgrades: $1,500
• Sales tax: $1,750
• Total eligible costs: $31,250

Federal Tax Credit:

• $31,250 × 30% = $9,375 credit

Your Net Cost:

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).

Q: Does the credit apply to DIY installations?

A: Yes, if you purchase and install your own system, you can claim the credit on equipment and materials.

Q: Can I combine the federal credit with state rebates?

A: Absolutely! The federal credit is based on your out-of-pocket cost BEFORE state rebates, so you benefit from both.

Frequently Asked Questions

Can I still qualify for the tax credit if I install in late 2025?

Yes, but you must act immediately. With typical 2-3 month installation timelines, you need to start the process NOW to have your system operational by December 31, 2025. After this date, the residential solar tax credit goes to 0%. Schedule your free assessment today.

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 reduce my federal tax credit?

No. The federal credit is calculated on your total out-of-pocket cost BEFORE state rebates. You benefit from both incentives separately, maximizing your total savings.

Can I claim the credit for a DIY solar installation?

Yes. If you purchase and install your own solar system, you can claim the 30% credit on all equipment and materials. However, professional installation ensures optimal performance and may be required for warranties. Compare options with ProsperShield.

What if my system spans two calendar years?

The credit applies to the tax year when your system becomes "placed in service" (operational and producing power). If installation starts in 2025 but completes in 2026, you miss the credit entirely. Install by Dec 31, 2025 to qualify.

Does the credit apply to batteries installed without solar?

Only if the battery is charged by renewable energy (like solar) at least 75% of the time. Batteries paired with solar installations automatically qualify for the full 30% credit. Explore solar + battery packages before the deadline.
