Understanding sales tax in South Carolina.
South Carolina state sales tax is 6.00%. However, when transacting within South Carolina, the total sales tax rate paid is often higher due to local county, city, or special district surtaxes.
How to Back Out Sales Tax in South Carolina
To separate the sales tax from the total paid gross amount for a transaction in South Carolina, use the standard reverse tax formula:
Base Price = Gross Amount / (1 + (Combined Tax Rate / 100))
For instance, if your combined tax rate (including South Carolina state rate of 6% and a local rate of 1.50%) is 7.5%, the formula becomes:
Base Price = Gross Amount / 1.0750
After deriving the base price, calculate the sales tax portion by subtracting it from the total gross amount.
