If you are planning to install solar panels in 2027, you may be wondering whether the solar tax credit 2027 will still be available. For U.S. homeowners, this is an important question because federal tax rules changed significantly after the passage of the One Big Beautiful Bill Act in 2025.
The federal Residential Clean Energy Credit (Section 25D), which previously allowed eligible homeowners to claim a 30% tax credit for qualifying solar energy installations, is no longer available for residential expenditures made after December 31, 2025. The Internal Revenue Service (IRS) confirms that the residential credit ended after 2025.
That means homeowners searching for the solar tax credit 2027 should not assume that the previous 30% federal solar tax credit will apply to a system installed in 2027.
However, solar incentives can still vary by state, utility company, local government and project type. This guide explains what changed, what homeowners should know before buying solar in 2027, and which other incentives may still be worth investigating.
What Is the Solar Tax Credit?
A solar tax credit reduces the amount of federal income tax an eligible taxpayer owes. Unlike a deduction, which reduces taxable income, a tax credit directly reduces qualifying tax liability.
For many years, the federal Residential Clean Energy Credit provided a major incentive for homeowners installing solar panels and other qualifying clean-energy equipment.
Under the previous rules, the Residential Clean Energy Credit was generally equal to 30% of qualifying costs for eligible residential clean-energy property. Qualifying expenses could include solar electric panels, solar water-heating equipment, battery storage technology and certain installation-related costs.
For example, under the old 30% credit:
- $20,000 solar installation → potentially $6,000 credit
- $25,000 solar installation → potentially $7,500 credit
- $30,000 solar installation → potentially $9,000 credit
These examples describe the former federal residential credit and should not be used to calculate a 2027 residential federal credit, because Section 25D is no longer available for expenditures after December 31, 2025.
Is There a Federal Solar Tax Credit in 2027?
For a typical U.S. homeowner, the federal Residential Clean Energy Credit is not available for solar expenditures made in 2027.
The IRS states that Section 25D, the Residential Clean Energy Credit, is not allowed for expenditures made after December 31, 2025.
This is an important change from the rules many solar websites published before 2025.
Older articles may still say that homeowners can receive a 30% federal solar tax credit through 2032, followed by lower percentages in later years. Those were the rules under the Inflation Reduction Act before the subsequent legislative changes. The current IRS guidance reflects the later termination of the residential credit.
Therefore, if you search for “solar tax credit 2027”, you should check the publication date of the information you find.
Why Did the 30% Solar Tax Credit End?
The residential solar tax credit was modified by federal legislation enacted in 2025.
The IRS now lists the termination of Section 25D among the changes to federal home-energy tax incentives. Under the updated rules, the Residential Clean Energy Credit is not allowed for expenditures made after December 31, 2025.
This means the date associated with the qualifying expenditure is extremely important.
A homeowner considering solar in 2027 should not simply rely on the old 30% federal credit calculation when estimating the project’s return on investment.
Can You Still Save Money by Installing Solar in 2027?
Yes. The end of the federal residential tax credit does not necessarily mean solar is no longer financially useful.
A solar installation can potentially reduce electricity purchases from the utility by generating electricity at the property.
Your potential savings can depend on factors such as:
- Solar system size
- Local electricity prices
- Electricity consumption
- Amount of sunlight
- Roof orientation and shading
- Utility net-metering or compensation rules
- Battery storage
- Financing costs
- System maintenance
- Local and state incentives
For this reason, homeowners should evaluate the total cost of solar versus expected electricity savings, rather than relying exclusively on a federal tax credit.
State Solar Incentives May Still Be Available
Although the federal residential solar tax credit has ended, individual states and local governments may have their own solar incentives.
Depending on where you live, incentives may include:
- State tax credits
- State rebates
- Property-tax incentives
- Sales-tax exemptions
- Utility rebates
- Performance-based incentives
- Net-metering or other electricity-compensation programs
- Local clean-energy programs
The availability, value and eligibility requirements can differ substantially between states.
For example, a homeowner in one state may have access to a state incentive while another homeowner may have no comparable program.
Therefore, before purchasing a solar system in 2027, check your state’s official energy agency, tax authority and local utility for current programs.
What About Solar Battery Storage in 2027?
Battery storage is another area where homeowners should be careful with older solar-tax-credit information.
Under the former Residential Clean Energy Credit, qualified battery storage technology could be eligible for the 30% credit. The IRS specifically included battery storage among qualifying residential clean-energy property under the previous rules.
However, because the residential Section 25D credit does not apply to expenditures after December 31, 2025, homeowners should not assume that purchasing a battery in 2027 automatically creates a federal residential tax credit.
Battery economics can still make sense in some locations, particularly where electricity rates, time-of-use pricing, outage protection or utility compensation policies make energy storage valuable.
What About Businesses Installing Solar in 2027?
The situation can be different for businesses and other eligible taxpayers.
The federal tax system has separate clean-electricity incentives for qualifying projects. The IRS describes the Clean Electricity Investment Credit under Section 48E as a technology-neutral credit for qualifying clean-electricity facilities and energy-storage technology.
The rules for commercial and utility-scale projects are different from the former residential Section 25D credit.
For eligible projects, the base investment credit is generally 6%, with the possibility of a higher credit when certain requirements are satisfied, including prevailing-wage and apprenticeship requirements. Additional increases may apply in certain circumstances.
Businesses considering solar in 2027 should therefore consult a qualified tax professional and review the current IRS rules applicable to their specific project.
How Should Homeowners Plan for Solar in 2027?
If you are considering solar panels in 2027, use a more comprehensive approach instead of calculating your investment around the old 30% federal credit.
1. Calculate Your Current Electricity Usage
Review at least 12 months of electricity bills.
Determine:
- Average monthly electricity consumption
- Annual electricity consumption
- Average electricity price
- Seasonal changes in usage
- Expected future electricity demand
This information can help determine an appropriate solar system size.
2. Compare Multiple Solar Quotes
Do not evaluate a solar installation based only on the advertised system price.
Ask installers for:
- Solar panel brand and model
- Inverter information
- System capacity
- Estimated annual production
- Warranty details
- Installation cost
- Financing cost
- Expected maintenance
- Battery cost, if applicable
- Estimated payback period
3. Check State and Local Incentives
Because the federal residential credit is no longer available for 2027 expenditures, state and local incentives may become more important in your financial calculation.
Check official sources before signing a contract because incentive programs can change.
4. Understand Your Utility’s Solar Rules
Solar savings depend partly on what happens to the electricity your system produces.
Your utility may have rules covering:
- Net metering
- Export compensation
- Interconnection
- Time-of-use rates
- Fixed charges
- Solar system size
- Battery storage
Always review the current utility rules rather than relying on information from an older solar quote.
5. Calculate the Payback Period
A basic solar payback calculation can be written as:
Payback Period = Total Solar Cost ÷ Annual Solar Savings
For example, if a system costs $20,000 after applicable incentives and produces $2,000 in estimated annual savings, the simple payback calculation would be:
$20,000 ÷ $2,000 = 10 years
This is only a simplified calculation. Financing, electricity-rate changes, maintenance, degradation, incentives and utility rules can change the actual economics.
Should You Wait Until 2027 to Install Solar?
There is no universal answer for every homeowner.
The decision depends on factors such as your electricity costs, available state incentives, solar installation prices, utility policies, financing rates and how long you expect to remain in your home.
The important point is that homeowners should not build a 2027 solar investment calculation around the former 30% federal Residential Clean Energy Credit.
If a salesperson tells you that a standard residential solar installation in 2027 automatically qualifies for the old 30% federal credit, ask for the specific current IRS rule supporting that claim.

Frequently Asked Questions About Solar Tax Credit 2027
1. Is there a 30% solar tax credit in 2027?
For typical residential solar installations, the former 30% federal Residential Clean Energy Credit is not available for expenditures made after December 31, 2025. Therefore, homeowners should not assume they can claim the old 30% federal credit for a residential solar installation in 2027.
2. Can I get a federal tax credit for solar panels installed in 2027?
The federal Residential Clean Energy Credit under Section 25D does not apply to expenditures made after December 31, 2025. Other federal clean-energy tax incentives may apply to certain qualifying commercial or energy projects, but these are different from the residential credit.
3. Are solar batteries eligible for a tax credit in 2027?
Homeowners should not assume that a residential battery purchased in 2027 qualifies for the former federal Residential Clean Energy Credit. The previous rules included qualifying battery storage, but Section 25D does not apply to expenditures made after December 31, 2025.
4. Can I still get a state solar incentive in 2027?
Possibly. State, local and utility solar incentives are separate from the federal residential tax credit and depend on where you live. Check your state’s official energy or tax agency and your electricity utility for current 2027 eligibility requirements.
5. Is solar still worth considering in 2027 without the federal tax credit?
Solar may still be financially beneficial for some homeowners because it can reduce electricity purchases and provide long-term energy savings. However, the economics depend on installation costs, electricity rates, utility rules, financing, available local incentives and your household’s energy consumption. Compare these factors before making a decision.
Final Thoughts
The solar tax credit 2027 landscape is different from the one many homeowners remember from previous years. The federal Residential Clean Energy Credit that provided a 30% incentive for qualifying residential solar expenditures was terminated for expenditures after December 31, 2025.
For homeowners considering solar in 2027, the best approach is to look beyond the federal tax credit. Compare installation prices, electricity savings, utility policies and available state or local incentives.
Most importantly, verify tax information using current IRS guidance before making a purchase. Solar tax rules can change, and older articles may continue to describe incentives that are no longer available.
