Important Update for 2026: The federal residential solar Investment Tax Credit (ITC) under Section 25D expired on December 31, 2025. If you installed solar before that date, you may still be able to claim it on your 2025 tax return. For new installations in 2026, there is no federal residential solar tax credit. This calculator focuses exclusively on state and local incentives that remain available.

What Happened to the Federal Solar Tax Credit?

The federal residential solar Investment Tax Credit (ITC), also known as the Section 25D credit, provided homeowners with a percentage-based tax credit on the cost of a solar installation. For systems installed from 2022 through 2032, the credit was 30% of the total system cost. It was one of the most powerful incentives driving residential solar adoption in the United States.

As of January 1, 2026, the residential ITC is no longer available. The credit was repealed as part of broader tax reform legislation, and no extension or replacement has been enacted. Homeowners who installed solar on or before December 31, 2025 can still claim the credit on their 2025 tax returns (or carry forward unused credit from prior years), but new installations in 2026 receive zero federal tax benefit.

It is worth noting that the commercial ITC under Section 48E still exists. This means solar lease and power purchase agreement (PPA) providers -- which are businesses, not homeowners -- may still access commercial tax benefits. This could keep lease and PPA rates somewhat competitive, even though the direct homeowner credit is gone.

State Solar Incentives Overview

With the federal credit gone, state-level incentives are now the primary financial drivers for residential solar. These come in several forms:

  • State Tax Credits: A percentage of system cost that reduces your state income tax bill. Available in states like New York, South Carolina, Arizona, and others.
  • Cash Rebates: Upfront payments or grants from state programs or utilities that directly reduce your out-of-pocket cost.
  • SRECs (Solar Renewable Energy Certificates): Tradeable certificates earned for solar electricity production. SREC markets in states like New Jersey, Massachusetts, and Illinois can provide hundreds to thousands of dollars per year in ongoing income.
  • Property Tax Exemptions: Many states exempt the added home value from solar panels from property tax assessments, saving you hundreds per year.
  • Sales Tax Exemptions: Some states exempt solar equipment from state sales tax, saving 4-8% of your system cost upfront.
  • Net Metering: While not a direct incentive, net metering policies let you earn credit for excess solar electricity sent to the grid, dramatically improving your payback period.

Other Ways to Save on Solar Without the Federal Credit

Even without the federal ITC, there are multiple paths to make solar affordable:

1. Declining Equipment Costs

Solar panel prices have dropped over 70% in the past decade. The average residential system cost in 2026 is $2.50-3.00 per watt before incentives, compared to $7+ per watt a decade ago. Even without tax credits, the raw economics have improved dramatically.

2. Net Metering

If your state offers full retail net metering, every kilowatt-hour your panels produce offsets a kilowatt-hour you would have bought from the utility. At $0.15-0.30/kWh in most states, this can mean $1,500-3,600+ per year in avoided electricity costs. Use our Net Metering Calculator to estimate your savings.

3. Solar Loans

Low-interest solar loans allow you to finance your system with monthly payments that are often lower than your current electric bill. Be aware of dealer fees that can inflate loan balances.

4. Solar Leases and PPAs

Since the commercial ITC (Section 48E) still exists, solar leasing companies and PPA providers may still offer competitive rates. You will not own the panels, but you can lock in electricity rates below retail with $0 down.

5. Utility Rebate Programs

Many individual utilities offer their own rebate programs independent of state policy. Check with your local utility for current offerings.

Frequently Asked Questions

Is the federal solar tax credit still available in 2026?
No. The federal residential solar Investment Tax Credit (ITC) under Section 25D expired on December 31, 2025. Homeowners who installed solar in 2025 or earlier could claim it, but systems installed in 2026 and beyond are not eligible for any federal residential solar tax credit.
Which states still offer solar tax credits or incentives in 2026?
Many states still offer their own solar incentives. Notable examples include New York (25% state tax credit up to $5,000), South Carolina (25% state tax credit), Arizona (25% up to $1,000), Massachusetts (15% up to $1,000 plus SMART program payments), and Maryland ($1,000 grant). Use the calculator above to see what is available in your specific state.
How much can I save with state solar incentives alone?
State incentives vary widely. Some states like New York offer up to $5,000 in tax credits, while others have minimal or no state-level incentives. Combined with utility rebates, SRECs, and net metering, total state and local incentives can range from $0 to over $10,000 depending on where you live and your system size.
What are SRECs and how do they work?
Solar Renewable Energy Certificates (SRECs) are tradeable credits earned for every megawatt-hour (MWh) your solar system produces. States with SREC markets (like New Jersey, Massachusetts, Maryland, and Illinois) require utilities to buy these certificates. SREC values vary by market -- in New Jersey they can be worth $150-200+ per MWh, providing significant ongoing income.
Can I still go solar without the federal tax credit?
Absolutely. Solar panel prices have dropped significantly, and many homeowners achieve payback in 6-10 years through energy savings alone, even without the federal credit. State incentives, net metering, SRECs, and declining equipment costs mean solar remains a strong financial investment in most of the country.
Are solar leases or PPAs affected by the loss of the federal credit?
Yes and no. The residential Section 25D credit is gone, but the commercial ITC under Section 48E still exists for businesses. Solar lease and PPA companies (which own the panels) may still be able to claim commercial credits, potentially keeping lease and PPA rates competitive. However, terms may be less favorable than in prior years.
