Sales Tax in South Carolina — What You Need to Know
South Carolina charges a 6% state sales tax on the sale of tangible personal property and some services. Local sales tax rates may also apply on top of the state rate. Combined sales tax rates across South Carolina can range from 6% to 9%, depending on the county or city where the sale is delivered.
Who Needs to Collect Sales Tax in SC
If your business sells taxable goods or services in South Carolina, you are responsible for collecting sales tax from your customers and remitting it to the state. Any retailer making sales in SC needs to comply. This includes:
- Retail stores and shops anywhere in South Carolina, including Greenville, Berea, City View, Brandon, and Powdersville.
- Restaurants and food service businesses that sell prepared food and drinks.
- Online sellers and remote retailers with over $100,000 in gross revenue in SC — even without a physical location in the state.
- Service providersthat offer taxable services under South Carolina law.
Before you can make retail sales, you must obtain a retail license from the South Carolina Department of Revenue. Every retailer pays a one-time $50 registration fee and applies through the MyDORWAY portal. You cannot legally collect sales tax without a retail license.
Certain goods and services are exempt from sales tax in South Carolina. Common exemptions include most non-prepared food items and prescription drugs. If a buyer claims an exemption, you are responsible for collecting a valid exemption or resale certificate to back up that transaction.
When to File — Due Dates and Filing Schedule
The South Carolina Department of Revenue requires most businesses to file sales tax returns on a monthly basis. Your return and payment are both due by the 20th of the month after the tax period ends. If the 20th falls on a weekend or holiday, the due date moves to the next business day.
Some businesses may qualify for a quarterly or annual filing schedule based on their sales tax liability. You must request this change from the South Carolina DOR. Until approved, your default is monthly filing. Regardless of your schedule, the due date rules stay the same — you must remit sales tax by the deadline for each tax period.
You must file a return every period — even if you had no taxable sales. Skipping a zero return can result in penalties and interest charges from the state. Those charges add up fast, which is why filing on time always makes sense — even when your balance is zero.
How Sales Tax Filing Works in South Carolina
Sales tax returns in South Carolina are filed through the MyDORWAY portal — the South Carolina Department of Revenue’s official platform for filing, payment, and account management. Every retailer with an active retail license must use MyDORWAY to report and pay sales tax.
Filing is a two-step process. First, you report your sales data — total sales, taxable sales, exempt transactions, and the tax you collected from customers. Then you remit the correct amount to the state. Both steps share the same due date.
If your sales tax liability is $15,000 or more per filing period, you’re required to file and pay electronically. Most small retailers in Greenville use MyDORWAY anyway — it’s the fastest and easiest way to stay on time.
You may also need to file Schedule ST-389 to report local taxes for sales delivered to specific counties or cities across South Carolina.
Quetzal Taxes handles the entire process, from registration to filing, so you never miss a deadline.

How often do I need to file sales tax in South Carolina?
Most businesses file sales tax returns monthly. Returns and payment are due by the 20th of the following month. You can request a quarterly or annual filing from the South Carolina DOR if you qualify. You must file a return every period — even if you collected no sales tax.
What is the sales tax rate in Greenville, SC?
The state sales tax rate in South Carolina is 6%. Local rates may also apply based on where your customer gets the goods. Combined tax rates across South Carolina can reach 9%. Because SC uses destination-based sales tax, the rate follows the ship-to address — not your store location.
What happens if I file my sales tax return late?
Late filing can mean penalties and interest from the South Carolina Department of Revenue. The longer you wait to pay, the more you owe. You also need to file even when you have zero taxable sales — missing a zero return triggers the same penalties. With Quetzl Taxes, you never miss a deadline.
Do I need a retail license to collect sales tax in SC?
Yes. You must obtain a retail license before making any retail sales in South Carolina. You can apply through MyDORWAY and pay the one-time $50 fee. If your business has more than $100,000 in gross revenue in SC, you must also register and collect sales tax — even if you’re located out of state.
