Solar Tax Credits in Utah

Qualifying for the Utah Solar Tax Credit

All of our customers with a taxable income qualify for the U.S. federal tax credit (it’s technically called the Investment Tax Credit). Utah customers may also qualify for a state tax credit in addition to the federal credit.

The Utah credit is calculated at 25% of the eligible cost of the system or $1600, whichever amount is less. The process to claim the Utah renewable energy tax credit is relatively simple and straightforward to follow. It involves filling out and submitting the state’s TC-40 form with your state tax returns each year.
