If you do business in South Carolina, you are required to obtain a South Carolina Tax ID Number. The exact taxes you will have to pay depends upon the nature of your business. For example, if you have employees, you are required to withhold taxes from your their income and forward those to the South Carolina Department of Revenue; and if you are a retailer, you must collect sales tax and forward that tax to the government. One form registers you with the state for business tax purposes.
