South Carolina R&D Tax Credit

Access to incentives is essential when choosing where to locate your research and development facilities. Fortunately, some great R&D tax incentives are available for companies operating in South Carolina. If you are planning to relocate your business or start a company in the area, it would be best to learn more about the South Carolina research tax credit and how it can benefit your organization.

South Carolina Research and Development Tax Credit

To be eligible for the South Carolina R&D incentive, you must claim a federal income tax credit (IRC § 41) for increasing research operations during a taxable year. Furthermore, you can claim it against corporate license fees, corporate income tax, and individual income tax. To apply, you’ll need to use SC Schedule TC-18.

To calculate the South Carolina R&D tax credit, you can use the requirements similar to the federal tax credit. However, you must apply them solely to your local QREs. In other words, the credit is equivalent to 5% of South Carolina’s QREs.

Furthermore, keep in mind that this incentive comes with a limit. Generally speaking, according to your tax liability, you must use the credit the same year you obtain it. In addition, after every other credit has been applied, your South Carolina research tax credit can’t exceed 50% of your tax due for the year.

That said, you are allowed to carry forward the unused credit for up to ten years. You can file an updated tax return for an out-of-statute year to claim a credit that can be carried over into one or more open years. However, the credit you carry over must be decreased by the amount you might have used in the years out of the statute.
