Federal incentives
Federal Residential Clean Energy Credit (25D)
30% for systems installed 2022–2025; not available for installations completed after December 31, 2025[1]
The 30% federal credit for homeowners who bought solar ended with Public Law 119-21. A system counts in the year its installation is completed, so paying in 2025 for a 2026 installation does not qualify.
- Who
- Homeowners who bought and installed a system by December 31, 2025 claim it on IRS Form 5695 for that tax year.
- Deadline
- December 31, 2025
- Checked
- November 5, 2026
Business credit for leased and PPA systems (48E)
Claimed by the system owner, not the homeowner; solar must begin construction by July 4, 2026 or be in service by December 31, 2027[2]
If a company owns the panels on your roof (a lease or power purchase agreement), that company may claim the business clean electricity investment credit and can reflect it in your price. You cannot claim it yourself.
- Who
- Third-party-owned systems (leases and PPAs). Ask the provider whether the price assumes this credit.
- Deadline
- December 31, 2027
- Checked
- November 5, 2026

How these incentives stack
Cash rebates are paid first and usually reduce the cost a tax credit is based on. State tax credits only help if you owe enough state income tax. Exemptions (sales and property tax) apply automatically or through a form, and they do not reduce what you owe the installer on paper, so check that a quote does not charge tax that the law exempts. The calculator applies the programs it can model and lets you switch utility rebates on or off.
FAQ
Frequently asked questions
Does Vermont have a solar tax credit?
No. Vermont offers exemptions and utility programs instead of a state income tax credit; see the list above.
Can I still get the federal solar tax credit?
No, not if you buy the system and installation is completed after December 31, 2025 (Federal Residential Clean Energy Credit (25D)[1]). If a company leases you the panels or sells you the power, that company may still claim a business credit and may pass some value on through the price.
