Solar Tax Credits and Incentives in 2026: State-by-State Guide

The Federal Investment Tax Credit (ITC)

The federal solar Investment Tax Credit is the single largest incentive for going solar. Established by the Energy Policy Act and extended through the Inflation Reduction Act of 2022, the ITC provides a dollar-for-dollar reduction in your federal income tax equal to 30% of your total solar installation cost.

The 30% rate applies to systems installed between 2022 and 2032. After that, the credit steps down to 26% in 2033, 22% in 2034, and expires for residential systems in 2035. This makes the next six years the optimal window for residential solar adoption.

What the ITC Covers

The ITC applies to a broad range of costs associated with your solar installation. Eligible expenses include solar panels, inverters (string, micro, or hybrid), mounting hardware and racking, electrical wiring and conduit, installation labor, permit and inspection fees, energy storage batteries (minimum 3 kWh), sales tax paid on equipment, and roof reinforcement directly related to supporting the panels.

For a typical 8 kW system costing $24,000 before incentives, the 30% ITC saves you $7,200 on your federal taxes. If you add a 13.5 kWh battery for $9,200, the total eligible cost becomes $33,200 and the credit jumps to $9,960. Use our Solar Savings Calculator to estimate your exact credit based on your system configuration.

How to Claim the Federal Solar Tax Credit

Claiming the ITC is straightforward but requires proper documentation. You must own the solar system (leased systems do not qualify), and the system must be installed on your primary or secondary residence in the United States. Rental properties qualify for the commercial ITC but not the residential credit.

File IRS Form 5695 (Residential Energy Credits) with your federal tax return for the year the system was placed in service. The system is considered placed in service when your utility grants permission to operate, not when installation is physically complete. Keep all invoices, contracts, and the interconnection agreement as supporting documentation.

The ITC is non-refundable, meaning it reduces your tax liability but cannot generate a refund. If your total federal tax liability is $5,000 and your solar credit is $7,500, you use $5,000 this year and carry the remaining $2,500 forward to future tax years until the credit is fully used. There is no expiration on the carryforward. For help understanding your tax liability, LevyIO's Tax Bracket Calculator can show exactly how the credit applies.

State Solar Tax Credits

Many states offer their own tax credits on top of the federal ITC. These are separate credits that stack, meaning you can claim both. State credits typically range from $1,000 to $6,000 and may be based on a percentage of cost or a fixed dollar amount per watt.

Notable State Tax Credits in 2026

• New York: 25% state tax credit, up to $5,000 for residential systems
• South Carolina: 25% state tax credit, no cap, with 10-year carryforward
• Arizona: 25% state tax credit, up to $1,000 (modest but stacks with high solar production)
• Massachusetts: 15% state tax credit, up to $1,000 (stacks with SMART and SRECs)
• Oregon: $2,500 state tax credit for solar, $2,500 additional for battery storage
• Utah: 25% state tax credit, up to $1,600
• Iowa: 15% state tax credit, up to $5,000, available through 2027

Check the Database of State Incentives for Renewables and Efficiency (DSIRE) at dsireusa.org for the most current information. State policies change frequently, and new programs are added regularly. Some states have annual budget caps that can exhaust funding before the end of the fiscal year.

Solar Renewable Energy Certificates (SRECs)

SRECs are tradeable certificates that represent the environmental attributes of solar electricity generation. For every 1,000 kWh (1 MWh) your solar panels produce, you earn one SREC. You can sell these certificates on the open market to utilities that need them to meet renewable portfolio standard (RPS) requirements.

SREC values vary dramatically by state and market conditions. In 2026, approximate values are: New Jersey TRECs at $80-$90 per MWh, Massachusetts SRECs at $200-$280 per MWh, Maryland SRECs at $50-$70 per MWh, Pennsylvania SRECs at $15-$25 per MWh, Illinois SRECs through the Adjustable Block Program at $60-$80 per MWh, and Washington D.C. SRECs at $300-$400 per MWh.

For a typical 8 kW system producing 10 MWh per year in Massachusetts, SREC income can reach $2,000-$2,800 annually. Over the typical 10-year SREC qualification period, this adds $20,000-$28,000 to your total solar value, often exceeding the cost of the system itself. This is separate from electricity savings and the federal tax credit.

Property and Sales Tax Exemptions

Solar panels typically increase your home value by $15,000 to $25,000 for a standard residential system. Without a property tax exemption, this increase would raise your annual property tax bill by $150 to $500 depending on your local tax rate. Fortunately, over 35 states offer full or partial property tax exemptions for solar energy systems.

States with 100% property tax exemptions include California, Colorado, Connecticut, Florida, Maryland, Massachusetts, New Jersey, New York, Texas, and Virginia, among others. Some exemptions are permanent, while others last 10 to 20 years. Check your county assessor's office for local implementation details.

Sales tax exemptions save you an additional 4-10% on equipment costs. At least 25 states exempt solar equipment from state sales tax. For a $25,000 system in a state with 7% sales tax, this exemption saves $1,750 immediately.

Utility Rebates and Performance Incentives

Many utilities offer direct rebates or performance-based incentives (PBIs) for solar installations. Rebates provide an upfront payment per watt installed, typically $0.10 to $0.50 per watt. Performance incentives pay you per kilowatt-hour generated over a multi-year period.

Massachusetts' SMART (Solar Massachusetts Renewable Target) program pays $0.06-$0.12 per kWh generated for 10 to 20 years, depending on system size and adders for battery storage, community solar, and low-income projects. An 8 kW system generating 10,000 kWh annually can earn $600-$1,200 per year through SMART alone.

New York's NY-Sun program provides upfront incentives ranging from $0.20 to $0.40 per watt for residential systems, reducing a $25,000 system cost by $1,600-$3,200. Combined with the state tax credit and federal ITC, New York homeowners can reduce their out-of-pocket solar cost by 55-65%.

Contact your utility directly or check the DSIRE database for available programs in your area. Many utilities also offer net metering, which credits you for excess solar electricity sent to the grid. Our Solar Savings Calculator factors in net metering savings alongside other incentives.

Battery Storage Incentives

Battery storage qualifies for the 30% federal ITC as a standalone system since 2023. Several states offer additional battery-specific incentives that stack with the federal credit, making energy storage increasingly affordable.

California's Self-Generation Incentive Program (SGIP) provides up to $1,000 per kWh for battery storage, with higher rates for equity customers and homes in high fire-risk areas. A 13.5 kWh battery can receive up to $13,500 through SGIP, potentially covering the entire cost when combined with the federal ITC.

Oregon offers a $2,500 state tax credit specifically for battery storage, separate from the solar credit. Connecticut provides $200 per kWh through its Residential Battery program. Maryland's Energy Storage Tax Credit offers 30% of costs up to $5,000. Vermont's Bring Your Own Device program pays battery owners up to $10,500 over 10 years for participating in grid stabilization events.

Virtual power plant (VPP) programs from utilities add recurring revenue. Some programs pay $30-$75 per month for allowing the utility to dispatch your battery during peak demand. Use our Solar Battery Calculator to model battery costs and savings with all available incentives.
