When two or more related corporations concurrently employ the same individual but compensate that individual through only one of the corporations, it’s a "common paymaster” relationship.
The total unemployment insurance contributions due are determined as if the individual has one employer—the common paymaster. The common paymaster is responsible for filing tax returns and issuing W-2s. However, when all related corporations pay the employee, each corporation is liable for unemployment insurance contributions.
South Carolina recognizes a common paymaster when all the following conditions exist:
- All corporations involved in a common paymaster relationship must be related. That is, they have some form of common ownership such as parent-subsidiary or are connected through stock ownership, board members, corporate officers, or employees.
- The corporation designated as the common paymaster must be an existing corporation and not newly established for that purpose.
- Any individual receiving wages through a common paymaster must be performing concurrent employment for two or more related corporations, one of which is designated a common paymaster.
- Pursuant to Treasury Regulation Section 307-7701-2, Parent-Subsidiary Legal Entities and Disregarded Entities cannot report their employee wages through a common paymaster.
