South Carolina Research Expenses Credit

A simple, broadly available credit with a long carryforward, frequently used by the state's manufacturing base.

Program Overview

South Carolina grants a credit equal to a percentage of qualified research expenses incurred in the state, using the federal Section 41 definition of qualified research. Unlike many states, the calculation is applied to total in-state qualified research expenses rather than to an increase over a base amount, which simplifies the analysis considerably. The annual credit is capped at a share of liability, but the ten-year carryforward preserves value for growing companies.

Eligibility

Taxpayers with qualified research expenses, as defined under IRC Section 41, for research conducted in South Carolina.

Benefits

Non-refundable credit limited to 50% of South Carolina tax liability after all other credits.
