Federal Solar Tax Credits Extended

Good News for Solar Enthusiasts: Now Extended Through 2034!

The Inflation Reduction Act of 2022 has extended the Federal Solar Tax Credit (ITC), giving homeowners and boat owners even more incentive to go solar. This tax credit applies to your primary or secondary residence—including certain boats with living accommodations (head, galley, and bunk) registered in the U.S.

Tax Credit Rate:

  • 2022–2032: 30% of total system costs
  • 2033: 26% of total system costs
  • 2034: 22% of total system costs
  • After Jan. 1, 2035: 0%

Eligibility:
You can claim this credit if you’ve made energy-saving improvements to your home (or qualifying boat) in the U.S. during the tax year. Qualified residences include:

  • Houses
  • Mobile homes
  • Condominiums
  • Cooperative apartments
  • Houseboats (with proper accommodations)

What’s Covered:
The credit applies to the cost of:

  • Solar panels
  • Batteries
  • Inverters
  • Charge controllers
  • Wiring and labor costs

Retroactive Eligibility:
Systems placed in service after January 1, 2006, can qualify if the credit hasn’t already been claimed.

Unused Credits:
If your tax liability is lower than the credit, you can roll over unused amounts to future tax years.
