The Federal Solar Tax Credit: What Its Expiration Means
The federal solar tax credit, officially the Residential Clean Energy Credit, was for years the most significant solar incentive in America: a direct, dollar-for-dollar reduction in federal income tax. That chapter closed on December 31, 2025. Homeowner-owned systems placed in service from 2026 onward receive no federal credit, and any quote or calculator that still shows one is out of date.
How the 30% Credit Worked, and Who Can Still Use It
The credit let homeowners claim 30% of the total cost of a solar energy system directly off federal tax liability (IRS), with “total cost” covering panels, inverters, mounting, wiring, labor and battery storage installed at the same time. If your system was placed in service by the December 31, 2025 deadline, that credit is yours, and one important detail survives the expiration: unused credit carries forward, so qualifying 2025 installers with more credit than tax liability can still be applying the remainder on current returns.
For example, a $25,000 system placed in service by the deadline earned a $7,500 credit. A homeowner whose tax liability that year was only $5,000 could wipe out the bill and roll the remaining $2,500 forward, which is exactly the situation many 2025 installers are still in today. If that is you, make sure the carryover appears on this year’s return.
The Critical Deadline: December 31, 2025
Federal legislation accelerated the expiration of this credit for homeowners, and the deadline has now passed: only systems fully installed and placed in service by December 31, 2025 qualified. Nothing installed after that date earns a federal residential credit under current law.
What this means in practice: the burden of making solar pay has shifted entirely to state and utility programs, your electric rate, and honest system sizing. It also means a new consumer trap has appeared, because plenty of sales material and online calculators still quietly include the expired credit. If a 2026 quote shows a 30% federal reduction, every payback number beneath it is wrong, and we would treat the error as a reason to question the rest of the quote too.
Who Could Claim the Credit Before It Ended?
Eligibility for the now-expired credit required a few key criteria, which still matter if you installed by the deadline and are claiming carryover on current returns:
Own your home
The system must be installed on a home you own. This can be your primary residence or a secondary home, like a vacation house.
Have sufficient tax liability
The credit can only reduce the tax you owe. If your income is low enough that you don’t owe any federal income tax, you won’t be able to take advantage of the credit.
Own your solar system
You must purchase the system outright, either with cash or through a solar loan. Homeowners who opt for a solar lease or a Power Purchase Agreement (PPA) are not eligible to claim the credit themselves. In those arrangements, the third-party company that owns the system receives the tax benefit, though they may pass some of those savings on to you in the form of a lower monthly payment.

State & Local Solar Incentives: Stacking Your Savings
With the federal ITC gone for homeowners, the incentives offered by states, municipalities and utility companies are the stack that remains, and where they exist they still reduce your costs meaningfully. While these vary widely by location, they generally fall into a few key categories.
Net Metering
While technically a billing mechanism rather than a direct incentive, net metering is one of the most important solar policies for homeowners. Think of it as “rollover minutes” for your electricity. When your panels produce more power than your home is using, that excess energy is sent to the grid. Your utility company tracks this and gives you credits on your bill, often at the full retail rate. Then, at night or on cloudy days when you need to pull power from the grid, you use those credits first before you have to pay. This policy is fundamental to maximizing your bill savings, ensuring you get full financial value for every kilowatt-hour your system produces.
State Tax Credits
Some states offer their own version of the solar tax credit, which reduces your state income tax liability. These are less common than other incentives but can be very valuable where they exist. For example, a state might offer a 10% tax credit. On a $25,000 system, this would provide an additional $2,500 in savings on your state taxes, which you could claim in addition to the $7,500 federal credit.
Cash Rebates
This is one of the most straightforward types of incentives. A cash rebate is a direct, upfront payment to you (or your installer) that immediately lowers the total cost of your system. These are often offered by:
Funded by the state to encourage renewable energy adoption and meet clean energy goals.
Offered by your local power company to help reduce overall demand on the electrical grid, especially during peak hours.
Rebates are often granted on a first-come, first-served basis and can run out of funding within the year, so it’s important to act quickly when they are available.
Performance-Based Incentives (PBIs)
Instead of an upfront discount, these incentives pay you for the actual electricity your solar system produces over time. The most common form is a Solar Renewable Energy Certificate (SREC).
- How SRECs Work: In some states with a Renewable Portfolio Standard (RPS), utilities are required to get a certain percentage of their electricity from renewable sources. To meet this mandate, they can purchase SRECs from homeowners. For every 1,000 kilowatt-hours (kWh) of electricity your system generates, you earn one SREC. You can then sell these SRECs on an open market. States like New Jersey and Massachusetts have historically had very strong SREC markets, providing homeowners with a significant and reliable annual income stream from their solar panels, often for 10 years or more.
Property & Sales Tax Exemptions
Many states have passed laws to ensure that going solar doesn’t increase your tax burden.
Property Tax Exemption
Installing solar panels is a valuable home improvement that increases your property value. In most states, a property tax exemption means that you will not be charged higher property taxes on the value added by your solar system. This is a crucial long-term financial benefit that saves you money year after year.
Sales Tax Exemption
Many states also exempt solar energy equipment from state sales tax. On a $25,000 system in a state with a 6% sales tax, this exemption saves you $1,500 right off the top, reducing the initial purchase price before any other credits or rebates are even applied.

Scenarios Where You Likely Won’t Qualify for Much
Incentive pages, ours included, can read as if every homeowner collects every program. The honest picture is narrower, and knowing where you stand before a sales conversation protects you from a quote built on savings you will never see:
- Renters and homeowners without roof ownership. Incentives follow the system owner. A landlord’s roof is not yours to claim against, and community solar operates under entirely different rules.
- Households with little state income tax liability in credit states. A state tax credit only pays out as fast as your tax bill can absorb it. Retirees and low-liability filers may wait years for value a quote shows arriving on day one.
- Homes under a lease or PPA. The third-party owner keeps the incentives; your benefit is limited to the rate written into your agreement.
- Low-usage homes in states with thin programs. With the federal credit expired and a modest electric bill, the math may simply not close. An honest installer will tell you that; this page exists so you can tell them first.
State-by-State Solar Incentive Landscape
The quality and quantity of solar incentives vary significantly from state to state. It’s important to remember that no homeowner in America receives a federal credit anymore, so these state-level programs are the entire incentive picture. The ratings below reflect what each state offers on its own. Even in a state with a standard incentive package, solar can still be a sound financial decision, it just has to earn that verdict through your electric rate and honest sizing rather than a federal head start.

Frequently Asked Questions
There no longer is one: the Residential Clean Energy Credit, also known as the Investment Tax Credit (ITC), expired for homeowners on December 31, 2025. Owners who placed systems in service before that date claimed 30% of system cost, and unused credit from those installations can still carry forward on current returns.
You can still stack state, local and utility incentives with each other, and since the federal credit’s December 2025 expiration stacking is where the real reductions now come from: pairing a state credit with a utility rebate does the work the federal credit used to do.
No. The ITC was a tax credit rather than a rebate: for systems that qualified before its December 2025 expiration, it reduced the federal income tax owed rather than arriving as a payment, and pre-deadline installers still applying carryover see it work the same way on current returns.
The best way is to get a quote from a qualified local installer, as they are experts on the specific and often changing programs in your area. You can also research your state on the DSIRE database, a comprehensive public resource that tracks renewable energy incentives.
For systems that qualified by the December 31, 2025 deadline, the IRS generally allows any credit beyond that year’s tax liability to roll forward to later returns, which is why some 2025 installers are still collecting theirs today.
