South Carolina has a structured approach to taxing the wages of both resident and nonresident remote employees with specific regulations regarding employer withholding obligations, sourcing of wages, and local tax implications.
-
Employer Withholding Obligations:
- An employer in South Carolina is required to withhold income tax for employees if their wages are expected to equal $1,000 or more during the year. This withholding applies to both resident and nonresident employees earning income within the state. However, nonresident employees' wages are exempt from withholding if they are earning in another state where taxes are withheld, and they provide a waiver under certain conditions (Document Chunk [2]).
-
Sourcing of Nonresident Wages:
- Nonresident wages are sourced based on whether the services are performed within South Carolina. If a nonresident individual is providing services in the state, their compensation becomes subject to South Carolina taxation, specifically when tied to tangible personal property or services performed within the state (Document Chunk [4]).
-
Reciprocity Agreements:
- South Carolina does not have reciprocity agreements with other states for withholding. This means that nonresident employees who earn income in South Carolina may be subject to taxation in the state regardless of where they reside, without special exemptions based on state partnerships (Curated Facts).
-
De-minimis Thresholds:
- The state does not explicitly recognize a de-minimis threshold for nonresident employees' wages in terms of a dollar amount; however, a general section implies that services performed by a nonresident employee may not be taxed if their gross wages from services in South Carolina are less than amounts defined in the Internal Revenue Code as non-taxable (Document Chunk [2]).
-
Local/City Wage Taxes:
- South Carolina does not impose local or city wage taxes on income earned, making it a straightforward taxation state from this perspective for both resident and nonresident employees (Curated Facts).
In conclusion, South Carolina maintains a conventional approach to wage taxation without a convenience of employer rule, lacks reciprocity for nonresident taxation, does not apply local wage taxes, and sources wages based primarily on where services are performed.
