Claim the 2025 Solar Tax Credit in 2026: Save $7,500–$9,000 on Your Home
The 2026 tax season is here, and many homeowners are surprised to learn that they can still take advantage of the residential solar tax credit from 2025. Even though the credit officially expired at the end of last year, a special loophole allows certain taxpayers to claim substantial savings on solar installations. This can mean as much as $7,500 to $9,000 in tax benefits if the work was completed before the cutoff.
In this article, we will explain what the solar tax credit is, how the loophole works, who qualifies, and why working with a Certified Public Accountant (CPA) can help you maximize your savings and avoid mistakes.
What Is the Residential Solar Tax Credit?
The Residential Energy Efficient Property Credit, commonly called the solar tax credit, is a federal incentive designed to encourage homeowners to install clean energy systems. It allows taxpayers to deduct a percentage of the cost of solar panels, solar water heaters, and other renewable energy equipment from their federal taxes.
For example, if you spent $20,000 on a solar installation, a 30% credit would allow you to reduce your federal tax bill by $6,000. This is directly applied to taxes owed, not just an indirect deduction.
The credit officially expired at the end of 2025, which left many people wondering if they could still claim any benefits. Fortunately, there is a loophole that can help some homeowners save money in 2026.
How the Loophole Works
The loophole involves commercial lease or purchase agreements that were executed before the credit’s expiration date. Here’s how it works:
- Pre-Agreement Timing
If a contract for the solar system was signed before the end of 2025, you may still qualify for the credit, even if the installation or final payment happens in 2026. - Eligible Costs
Costs that can qualify include solar panels, inverters, wiring, and installation labor. Some other equipment like battery storage may also qualify if it is installed alongside the solar system. - Claiming the Credit
Taxpayers claim the credit on their federal tax return. The amount of the credit is based on the total eligible costs outlined in the signed agreement, not when the work was finished. - Savings Range
Depending on the size and cost of the solar system, the tax savings can range from $7,500 to $9,000 or more. This can make a big difference for families and homeowners looking to reduce utility costs.
Who Qualifies for the Credit
Not every homeowner can take advantage of this loophole. Here are the main eligibility requirements:
- Homeownership: You must own the home where the solar system is installed. Rental properties do not qualify.
- Pre-2026 Agreements: The purchase or lease agreement must have been signed before the credit expired at the end of 2025.
- System Requirements: The solar system must meet federal standards for residential energy efficiency.
- Tax Liability: You must have enough federal tax liability to use the credit. If the credit exceeds your tax owed, it may carry over to future years.
This loophole is particularly useful for homeowners who signed contracts in 2025 but had installation delayed until 2026.
Benefits of Claiming the Solar Tax Credit
Claiming the solar tax credit can provide multiple benefits beyond just reducing your federal taxes:
- Lower Utility Bills
Solar panels produce electricity from sunlight, which reduces your reliance on the grid and lowers monthly energy bills. - Increased Home Value
Homes with solar systems are often more attractive to buyers. Installing solar can increase your home’s market value. - Environmental Impact
Using solar energy reduces carbon emissions and reliance on fossil fuels. This makes your home more eco-friendly. - Long-Term Savings
While installation costs can be high upfront, the combination of tax credits and energy savings often makes solar a smart long-term investment.
Why You Should Work With a CPA
Navigating tax credits and loopholes can be complicated. A Certified Public Accountant (CPA) can help you ensure you maximize your savings and stay compliant with IRS rules. Here’s why hiring a CPA is important:
- Expert Knowledge: CPAs understand the rules for federal and state energy credits and can ensure you meet all requirements.
- Accurate Filing: A CPA helps you avoid mistakes on your tax return, which reduces the risk of audits or penalties.
- Tax Planning: CPAs can help you plan payments and deductions to maximize benefits, especially if you are carrying the credit over multiple years.
- Peace of Mind: Knowing a professional is handling your taxes reduces stress and ensures your claim is accurate.
Steps to Claim the Credit
Here’s a simple guide to claiming the solar tax credit under this loophole:
- Gather Documents
Collect your pre-2026 purchase or lease agreement, invoices, and proof of installation. - Verify Eligibility
Make sure your system and home meet the IRS requirements for residential solar energy credits. - Calculate the Credit
Add up all eligible costs from the agreement. Multiply by the credit percentage to determine your total savings. - File With Your Tax Return
Use IRS Form 5695 to claim the Residential Energy Efficient Property Credit. Include all required documentation. - Consult a CPA
Before filing, review your calculation with a CPA to ensure accuracy and maximize your credit.
Potential Risks and Considerations
While the loophole is legitimate, there are some risks to be aware of:
- Incorrect Filing: Filing without proper documentation could delay your refund or trigger an audit.
- Expired Agreements: Only agreements signed before the end of 2025 qualify. Contracts signed in 2026 do not.
- System Changes: Modifications to the solar system that significantly change cost or components may affect eligibility.
A CPA can help you navigate these risks and ensure your credit is applied correctly.

By understanding the rules, documenting your agreements, and working with a CPA, you can maximize your savings and enjoy the long-term benefits of solar energy.
With energy costs rising and clean energy becoming more important, taking advantage of this credit is both financially smart and environmentally responsible.
