Understanding how solar panel tax credits work

The federal tax credit is for solar expenditures (including equipment and installation costs) with no upper limit.

Please note that the federal solar panel tax rebate will end in 2021, and that the amount of tax credit one can receive decreases over the years.

  • 30% for systems placed in service by 12/31/2019
  • 26% for systems placed in service after 12/31/2019 and before 01/01/2021
  • 22% for systems placed in service after 12/31/2020 and before 01/01/2022


Applying for federal credit for solar panels

To claim the credit for residential systems, you must file IRS Form 5695 to report your expenses.
To claim the credit for commercial systems, you must file 
IRS Form 3468 to report your expenses.

If the federal solar tax credit exceeds tax liability, the excess amount may be carried forward to the succeeding taxable year. The excess credit may be carried forward until 2021, but it is unclear whether the unused tax credit can be carried forward after then.
