Starting January 1, 2026, significant updates to the federal solar tax credit are now in effect, meaning homeowners who were previously planning on taking advantage of this incentive must be aware of the new changes.
The Residential Clean Energy Credit, the government’s primary incentive for solar installations, has undergone adjustments that will affect the tax savings homeowners can claim for solar systems installed in the coming years. Understanding these guidelines is essential to maximizing the benefits and avoiding potential confusion when filing your taxes.
For those considering solar energy in 2026, the key changes in federal tax law will influence your decision-making. From credit percentages to eligibility requirements, homeowners need to understand the impact on installation costs and tax filing to fully benefit from the program before the more substantial reductions in benefits kick in.
What Is the Federal Solar Tax Credit?
The Residential Clean Energy Credit (Section 25D) allows U.S. homeowners to claim a percentage of the costs for installing renewable energy systems, including solar panels, solar batteries, and geothermal heat pumps, against their federal taxes.
This credit has been one of the most impactful incentives in encouraging solar adoption across the United States, making renewable energy more affordable for homeowners.
Under the 2023-2025 guidelines, homeowners could receive a 30% tax credit for installing solar systems, which has significantly lowered the upfront costs. However, these benefits are now changing in 2026, affecting how homeowners can claim the credit for solar energy systems.
Key Updates for 2026: What Has Changed?
1. Expiration of Full 30% Credit for New Installations
As of January 1, 2026, the 30% tax credit for residential solar systems will no longer be available for new installations. Instead, homeowners who install solar systems after December 31, 2025, will only qualify for a 22% tax credit. This marks a reduction in the financial benefit available to homeowners who decide to go solar after 2025.
- For installations completed in 2025, homeowners can still claim the full 30% tax credit on their 2025 federal tax filings.
- For installations after December 31, 2025, the credit will decrease to 22%, with no further extensions or additional percentage increases available.
2. Homeowners Must Act Before 2026 to Maximize Benefits
Homeowners hoping to benefit from the 30% federal tax credit must have their solar systems installed and fully operational before December 31, 2025. This gives homeowners approximately a year to take full advantage of the credit before it reduces.
- Claim the full 30% tax credit: The credit applies to solar systems installed and placed in service before December 31, 2025.
- 22% tax credit: Solar systems installed after January 1, 2026, will be eligible only for the 22% credit, significantly reducing the savings available.
3. No Retroactive Claims After 2025
While the new 22% tax credit applies for installations after 2025, the IRS has confirmed that homeowners cannot apply the full 30% credit retroactively for systems that are installed in 2026 or beyond. Homeowners need to complete their solar installations before 2026 to be eligible for the higher credit. (energy.gov)
What About Solar Battery Storage and Other Systems?
In addition to solar panels, the tax credit also covers solar battery storage systems, solar water heaters, and geothermal heat pumps. However, the expiration date for the full 30% credit applies to all eligible energy-saving systems installed before December 31, 2025.
If you plan to install a solar battery or related technology, it’s important to have it completed before 2026 to qualify for the full credit.
Solar Battery Storage Systems
Homeowners adding battery storage to their solar installations can also benefit from the tax credit. Under the new guidelines, the 30% credit still applies to solar battery systems if they are installed and operational by December 31, 2025. After this date, the credit will drop to 22% for new battery storage systems.
- Maximize the benefit: If you plan to install a solar battery along with your solar panels, aim to complete the installation before 2026 to take full advantage of the 30% tax credit.
Claim the Credit: Documentation and Filing
To claim the Residential Clean Energy Credit for 2025 or 2026, you’ll need to ensure that the solar system is installed and operational before the specified deadline. You’ll also need to file the IRS Form 5695 with your federal tax return to claim the credit.
IRS Form 5695: The Key to Your Claim
- IRS Form 5695 is used to calculate and claim the Residential Clean Energy Credit for solar systems, battery storage, and other renewable energy systems installed on your property.
- Ensure you keep track of all expenses related to your solar installation, including labor, equipment, and permits. These costs count toward the total price that qualifies for the credit.
Once the system is installed and operational, submit the required documentation to the IRS when filing your 2025 tax return for systems installed before December 31, 2025, or your 2026 tax return for systems that are eligible for the 22% credit.
State-Level Solar Incentives
While the federal tax credit changes may significantly impact homeowners, it’s important to note that many states still offer additional incentives for solar installations. These state incentives can offset the reduction in the federal credit and make solar even more attractive to homeowners in certain regions.
Examples of State-Specific Programs
- California: State solar tax credits can still provide up to $3,000 for residential solar installations.
- New York: The NYSERDA incentive program offers rebates for residential solar installations, which may cover a portion of installation costs.
- Massachusetts: The Solar Massachusetts Renewable Target (SMART) program offers a performance-based incentive for homeowners installing solar systems.
Homeowners should check with local utility providers and state programs to see which incentives are still available in their area. These programs can help minimize the impact of reduced federal tax credits and still make solar a financially attractive option.
What Should Homeowners Do Now?
With the 2026 tax credit changes quickly approaching, it’s essential for homeowners to act quickly if they want to take advantage of the full 30% federal tax credit. Here’s a step-by-step guide to help you prepare:
- Start Your Research: Contact local solar installation companies and obtain quotes for your home’s solar system. Understand the costs and benefits of the systems available to you.
- Schedule Installation: Aim to have your system installed and operational before December 31, 2025, to qualify for the full 30% federal tax credit.
- Secure Financing: Explore solar loans, leasing options, or financing through your utility to help cover the upfront costs of solar installation.
- Consult with a Tax Professional: Given the complexity of tax laws and the new changes, it’s a good idea to speak with a tax advisor to ensure you are prepared for the tax filing and to maximize your credit claims.
- Check State and Local Incentives: In addition to federal incentives, look for state-level rebates and credits that may help reduce your costs.
