South Carolina extends COVID-19 income tax relief for teleworkers through December 31, 2021
The South Carolina Department of Revenue announced in SC Information Letter #20-22 that it is extending through December 31, 2021, its income tax withholding relief and the assertion of nexus for employees working from home temporarily within and outside of the state due to COVID-19. The Department had previously extended this relief through September 30, 2021 in SC Information Letter #21-08.
Income tax withholding
Under the normal circumstances, South Carolina employers located in the state are required to withhold income tax from the wages of residents and nonresidents working within the state. If South Carolina residents work outside of the state, those wages are not subject to South Carolina income tax withholding if the wages are subject to income tax withholding in the state where those wages are earned. (SC Code Section 12-8-520 .)
Pursuant to the COVID-19 emergency, and from the period March 13, 2020, through September 30, 2020 (extended to December 31, 2021), the Department will not use the temporary change of an employee's work location due to COVID-19 to impose the income tax withholding requirement under SC Code Section 12-8-520; however, this relief does not apply to workers whose status changed from temporary to permanent assignment during this period.
During the COVID-19 relief period, a South Carolina employer's income tax withholding requirement is not affected by the current shift from employees working on the employer's premises in South Carolina to teleworking from outside of South Carolina. Accordingly, the wages of employees temporarily working remotely in another state instead of their South Carolina business location continue to be subject to South Carolina withholding.
Further, during the COVID-19 relief period, an out-of-state employer is not subject to South Carolina's income tax withholding requirement solely due to the shift from employees working on the employer's premises outside of South Carolina to teleworking from South Carolina. Accordingly, the wages of a South Carolina resident employee temporarily working remotely from South Carolina instead of their normal out-of-state business location are not subject to South Carolina withholding if the employer is withholding income taxes on behalf of the other state.
The Department will not use changes solely in an employee's temporary work location due to the remote work requirements arising from, or during, the COVID-19 relief period (March 13, 2020 — December 31, 2021) as a basis for establishing nexus or altering apportionment of income.
