How much is sales tax in South Carolina?
The state base rate is 6%, and combined local rates range from 6% to 9.57%. The state's average combined rate sits at 7.61%. South Carolina has 554 taxing jurisdictions—a significant number—with the highest rate at 9.57% in Edisto Island. This patchwork means your location matters.
Your ZIP code alone won't tell you the rate. Tax jurisdictions don't follow ZIP boundaries, and neighboring streets might be in different taxing areas. That's why entering a specific address into a rate lookup—or using an API like Sefro's—gives you the actual combined rate you need to charge or pay.
What's taxed and what's exempt in South Carolina
Groceries are exempt from South Carolina sales tax, which is a break for consumers and businesses alike. Clothing purchases, however, are fully taxable. Don't assume a category without checking first.
SaaS and digital software are subject to South Carolina sales tax, meaning cloud-based subscriptions and online services are taxable. Prescription medicines remain exempt. Since tax treatment varies by category and the rules aren't always obvious, it's smart to verify each product type.
Do you have to collect South Carolina sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, South Carolina requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into South Carolina per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm South Carolina's current threshold before you rely on it.
If you sell into South Carolina from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate South Carolina sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 7.61% means about $7.61 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
That's what Sefro does. One API call returns the combined state, county, city, and special-district rate for any US address, sourced from state Departments of Revenue and refreshed weekly. You can also calculate the full tax on an order, validate addresses, and pull return-ready reports. See how the data is sourced or pricing to start.
