If you installed solar this year, the 30% federal solar tax credit 2025 could significantly reduce your federal tax bill. This credit allows homeowners to claim 30% of their qualified solar installation costs when filing their taxes, but many people are unclear on how it actually works and how to properly claim it.
We are not tax advisors and this is not tax advice. Every homeowner’s situation is different. You should always confirm details with your CPA or tax professional. That said, we work in solar every day and understand the general IRS guidance, so here is a clear breakdown of how the 30% federal solar tax credit 2025 works.
What Is the 30% Federal Solar Tax Credit 2025?
The 30% federal solar tax credit 2025 is officially called the Residential Clean Energy Credit. It allows you to claim 30% of the total cost of your solar energy system as a federal income tax credit
This credit applies to:
- Solar panels
- Inverters
- Racking and mounting equipment
- Electrical balance of system
- Labor for onsite preparation, assembly, and installation
- Permitting and inspection fees
- Energy storage systems paired with solar, if they meet eligibility requirements
The system must be installed on a home you own in the United States. It can be your primary or secondary residence, but it cannot be a rental property where you do not live (those properties are typically treated as business property and are generally eligible for the commercial tax credit instead).
The credit is currently scheduled at 30% for systems placed in service during 2025 under the Inflation Reduction Act.
What Tax Form Do You Use?
Homeowners claim the residential solar tax credit using:
Form 5695 is titled “Residential Energy Credits.” This is where you calculate your total eligible costs and determine your credit amount.
The credit then flows to your main tax return, which is:
Step-by-Step: How the Process Works
1. Gather Your Solar Project Costs
You will need:
- Your final invoice(s) from your solar installer
- Proof of payment (receipts from your solar installer typically work)
- Documentation showing the system was placed in service in 2025
To show your system was placed in service in 2025, you should keep documentation such as your final inspection approval, your utility’s Permission to Operate letter, or a signed certificate of completion from your installer showing the system was fully installed and operational in 2025. Signing a contract or paying a deposit in 2025 is not enough; the system must actually be installed and producing power.
Your eligible cost generally includes the full contract price for the system, less any rebates that reduce your out-of-pocket cost at the time of purchase. Performance-based incentives, like SRECs, typically do not reduce the eligible system cost because they are paid after installation.
Again, confirm this with your tax professional.
2. Complete IRS Form 5695
- You enter your total qualified solar electric property costs.
- You multiply that number by 30%.
- The form calculates your allowable credit.
For example:
If your total eligible cost was $25,000
30% of $25,000 = $7,500
That $7,500 is your potential tax credit.
3. Apply the Credit to Your Tax Liability
The Residential Clean Energy Credit is a nonrefundable tax credit.
That means:
- It reduces the federal income tax you owe.
- It does not create a refund beyond your total tax liability.
If you owe $8,000 in federal taxes and your credit is $7,500, your tax bill could be reduced to $500.
If you owe only $4,000 in taxes and your credit is $7,500, you may use $4,000 this year and carry the remaining $3,500 forward to future tax years.
The credit can be carried forward as long as the program remains in effect, subject to IRS rules.
Important Things to Know
It Is a Tax Credit, Not a Rebate
A tax credit reduces the federal income taxes you owe; it is not a check mailed to you automatically after installation. However, if you already had taxes withheld from your paycheck during the year and the solar credit lowers your total tax bill, you could receive a larger refund when you file because you overpaid relative to your final tax liability.
You Must Have Tax Liability
If you do not owe federal income tax, you may not be able to use the credit immediately. Unused portions can often be carried forward, but this depends on your situation.
The System Must Be “Placed in Service”
Generally, the system must be fully installed and operational in 2025 to qualify for the 30% credit in that tax year.
What About Leases or PPAs?
If you chose a solar lease or power purchase agreement, you can not claim the tax credit. In those cases, the system owner, usually the financing company, claims the credit.
If you purchased the system with cash or a loan and you are the system owner, you are generally the one eligible to claim the credit.
