Your application paperwork

Form to file: SC Schedule TC-38 (Solar Energy or Small Hydropower System Credit), filed with SC1040TC

South Carolina gives a state income tax credit for installing a solar energy system on a home you own. The credit is the lesser of 3,500 dollars per facility or 50 percent of your tax liability, and any unused amount carries forward up to 10 years. You claim it on Schedule TC-38, filed with the SC1040TC and your state return.

Steps to apply

  1. Have a solar energy system installed on your South Carolina home (placed in service on or after January 1, 2016) and keep the invoice.
  2. Complete SC Schedule TC-38 for the solar energy credit.
  3. Carry the credit to the SC1040TC and file it with your South Carolina income tax return.
  4. If the credit is larger than this year's tax, carry the unused amount forward (up to 10 years).

Documents you will likely need

  • An itemized invoice for the installed solar energy system.
  • Proof of payment.
  • Your interconnection agreement with the utility (it certifies the system was reviewed).
  • Your South Carolina income tax return with Schedule TC-38 and the SC1040TC.

Requirements vary by program and locality. Confirm the exact rules on the official program page. We can help you prepare your paperwork, but you submit it yourself.
