The Small Business Tax Workshop sponsored by the Internal Revenue Service will answer many of your taxation questions.  This workshop is free, in most instances, and is typically conducted multiple times per year in locations throughout the state.  See http://www.irs.gov/businesses/small/article/0,,id=99169,00.html for the current schedule.  See www.scdor.gov and www.sctax.org.

Income Tax
What and when you owe the federal and state government will depend upon the legal structure that you choose.  Once you have selected the legal structure that makes the most sense for you, ask your accountant about your federal and state tax requirements!  See www.irs.gov or www.sctax.org.
 
State Sales Tax
Contact the Sales and License Division of the S.C. Department of Revenue to determine if you are required to collect and pay sales tax.  If you are required to collect and pay this tax, you will need a S.C. tax identification number. See www.sctax.org.

Withholding Taxes for Employees
You are required to withhold these taxes from the wages paid to your employees: federal income tax, state income tax, and F.I.C.A (Social Security).

Unemployment Taxes
As an employer, you are required to pay unemployment taxes.  Contact the I.R.S. at 1-800-829-1040 for information about the Federal Unemployment Tax (F.U.T.A.), and the S.C. Employment Security Commission at (803) 792-7046 for information about the State Unemployment Tax (S.U.T.A).
