Federal tax treatment
By default, a single-member LLC is often disregarded for federal income tax purposes and a multi-member LLC is often taxed as a partnership. An eligible LLC can elect corporate tax treatment. That choice affects federal returns, owner reporting, payroll, and estimated taxes.
South Carolina sales tax
South Carolina imposes a 6% statewide sales tax on sales of goods and certain services, with possible local additions. A business making covered retail sales generally needs a Retail License before starting sales and must file sales-tax returns through the Department of Revenue.
Pass-through versus corporate taxation
Most LLCs are treated as pass-through entities unless they make a corporate tax election. A pass-through LLC can still have South Carolina income-tax and withholding obligations through its owners or employees. An LLC taxed as a corporation can have corporate tax returns and related filings.
Employer filings
When hiring, review South Carolina withholding, unemployment insurance, new-hire reporting, wage reporting, and workers’ compensation requirements. The EIN is only the federal identifier.
Keep the registrations separate
- LLC formation: creates the South Carolina LLC
- EIN: federal IRS identifier
- Retail License: permission to make covered retail sales
- Sales-tax returns: tax filing obligations through SCDOR
- Employer accounts: withholding, unemployment, and related obligations
- Local business licenses: county and municipal rules
- Corporate tax filings: separate obligations after a corporate tax election
