What Is the Federal Solar Investment Tax Credit?
The federal solar tax credit is a reduction in the amount of federal income tax you owe when you install a solar energy system at your home or business. Rather than receiving a check from the government, the credit lowers your tax liability dollar-for-dollar. If you install solar panels or other solar equipment, you may be able to claim a percentage of that cost as a credit on your federal tax return.

The credit works differently than a tax deduction. A deduction reduces the income amount that gets taxed, while a credit directly reduces the taxes owed. For example, if you owe $5,000 in federal taxes and have a $2,000 credit, you would owe $3,000 instead. This makes tax credits more valuable than deductions of the same amount.
The solar tax credit has existed since 2006 and has been updated several times. The percentage of costs you can claim has changed over the years, and future changes are possible. Understanding the current rules helps you make informed decisions about solar investments. The credit applies to residential solar installations, including rooftop panels, solar water heaters, and battery storage systems used with solar.
Practical Takeaway: Before investing in solar equipment, research the current credit percentage and learn how it applies to your specific situation. Contact the IRS or a tax professional to understand how this credit would affect your personal tax situation.
Who Can Claim the Solar Tax Credit and What Systems may have access to
The solar tax credit generally applies to homeowners and business owners who install may have access to solar equipment. For residential properties, you must own the home where the solar system is installed — renters typically cannot claim this credit. The property must be located in the United States, including territories like Puerto Rico under certain conditions.

Several types of solar equipment may may have access to for the credit. Photovoltaic (PV) panels that convert sunlight directly to electricity are the most common. Solar water heaters that use the sun to heat water for household use also may may have access to. Some solar heating and cooling systems for pools and hot tubs can may have access to as well. Battery storage systems that work with solar installations have also been added as may have access to equipment in recent years, expanding what homeowners can include.
The equipment must meet specific manufacturing and performance standards set by the Department of Energy. Equipment must be new when installed — used or secondhand systems do not may have access to. Installation must occur at a property in the United States where you have an ownership interest. Commercial solar systems at businesses have different rules, and those systems may have separate tax treatment.
Importantly, leased solar systems generally do not may have access to the homeowner for the credit. The person or entity that owns the solar equipment is the one who may claim the credit. If you lease solar panels, the solar company that owns them may claim the credit instead, though they might pass some benefit to you through lower lease payments.
Practical Takeaway: Review your solar equipment documentation and any technical specifications to confirm the equipment meets the required standards. Determine whether you will own or lease the system, as this significantly affects your ability to claim the credit.
How to Calculate the Solar Tax Credit Amount
The credit is calculated as a percentage of the total cost of your solar installation. The cost includes equipment, labor for installation, and certain related expenses. You do not include costs for financing, loan interest, or fees charged by contractors beyond the actual installation work.

The percentage you can claim has changed over time. In recent years, the percentage has been 30% of may have access to costs. This means if your total solar installation costs $10,000, you could potentially claim a $3,000 credit. However, future legislation may change this percentage, so you should verify the current rate when planning your installation.
Some costs may not be included in the calculation. Costs for removing or replacing old equipment, labor costs that your utility company may cover, and costs covered by rebates or other incentive programs typically reduce the amount you can claim. You calculate the credit based on your net out-of-pocket costs after removing these other funding sources.
If the credit exceeds the federal taxes you owe in a given year, you may be able to carry the unused portion forward to future tax years. This carryover provision means that even if you do not owe enough in taxes to use the full credit when ready, you may still claim it later. Keep documentation of your installation costs, receipts, and any invoices in case you need to support your tax return.
Practical Takeaway: Gather all solar installation invoices and separate the equipment costs from other expenses. Work with a tax professional to calculate the exact credit amount based on your situation and to understand how much credit you can actually use in the current tax year.
Filing Your Tax Return to Claim the Credit
To claim the solar tax credit, you file it on your federal income tax return. The specific form used depends on the type of system and your situation. For most residential solar installations, you use IRS Form 5695, "Residential Energy Credits," and submit it with your annual Form 1040 tax return. This form asks for information about your system, installation date, and the costs you paid.

You should file your return with a tax professional or use tax preparation software that supports this credit. The process requires accurate information from your solar installer, including the equipment specifications and installation completion date. Many reputable solar companies provide a document that lists all the information needed to file the credit. Request this document from your installer and keep it with your tax records.
The timing of when you file your return matters. You must claim the credit on the return for the tax year in which the solar system was installed and operational. If your system was installed and turned on in December 2023, you would claim the credit on your 2023 tax return filed in 2024. Do not wait years to file — the sooner you file, the sooner you receive any refund or tax reduction.
Common mistakes include miscalculating the cost basis, including ineligible expenses, or missing documentation. Keeping detailed records makes the filing process smoother. Store your solar installation contract, paid invoices, the installer's equipment certification, and proof of system set up date. If the IRS has questions about your claim, these documents support your filing.
Practical Takeaway: Request the IRS Form 5695 instructions and any documentation your solar installer provides about your system. Work with a may have access to tax preparer who has experience with solar tax credits to may support you claim the credit correctly on the right tax year.
State and Local Tax Incentives Beyond the Federal Credit
Many states and local governments offer additional incentives for solar installation beyond the federal tax credit. These may include state tax credits, rebates, performance payments, or other programs. Combining these programs with the federal credit can significantly reduce your net cost for going solar. Researching what programs exist in your area helps you understand your full financial picture.

State tax credits work similarly to the federal credit — they reduce state income tax owed. Some states allow you to claim both the federal and state credits. Other states have rebate programs that provide cash back after installation, reducing your out-of-pocket costs directly. Some utility companies offer rebates for customers who install solar, managed through the utility rather than through tax filings.
Property tax exemptions exist in many states, protecting solar installations from increasing your property tax assessment. Solar renewable energy credits (SRECs) in certain states allow you to sell credits generated by your system's power production. Net metering programs, where utilities credit you for excess power sent back to the grid, provide ongoing benefits beyond a one-time credit.
To research what programs may be available where you live, check your state's energy office website, contact your local utility company, and search for databases that list incentive programs by state. Programs change frequently and have different rules about income limits, equipment types, and system sizes. Taking time to research prevents missing opportunities or claiming a program you do not actually may have access to for under that program's specific rules.
Practical Takeaway: Visit your state energy office website or use the Database of State Incentives for Renewables & Efficiency (DSIRE) to learn what solar programs exist in your location. Contact your utility company to ask about any rebates or net metering programs they offer.
