Selling on eBay, Poshmark or Etsy from South Carolina: sales tax and 1099-K rules

On a marketplace sale delivered to South Carolina, the marketplace facilitator is the retailer and remits state and local sales and use tax on everything sold through its marketplace, and a person whose products are sold only through marketplace facilitators is not a South Carolina retailer and is not required to obtain a retail license. The South Carolina Department of Revenue documents we checked say nothing about a separate South Carolina 1099-K rule.

Who collects the tax on a marketplace sale

A marketplace facilitator is a retailer: it holds a South Carolina retail license and remits state and local sales and use tax on all products sold through its marketplace, whether it or a third party owns or delivers them. When a facilitator is made up of several related entities, the one that lists or advertises the products remits.

If you sell only through marketplaces

The Department says a person whose products are sold exclusively through a marketplace facilitator is not a South Carolina retailer, regardless of nexus, and is not required to obtain a retail license or remit tax on those sales. Its FAQ separately says a South Carolina seller selling from home through its own website must obtain a retail license and remit tax on orders shipped to South Carolina addresses.

Registration, resale certificates and what changes when you also sell direct have their own page: South Carolina: seller's permit and resale certificate rules.

The law: S.C. Code Ann. §§ 12-36-70 and 12-36-71 (Act No. 21 of 2019), effective .

South Carolina's sales tax

The general state sales and use tax rate is 6%, and local sales and use taxes are added by location. Separate state rates apply to accommodations (7%) and some other items.

Form 1099-K: South Carolina and the federal test

Information Letter #19-14, the Department's sales tax FAQ chapter and its withholding page, read for this page, say nothing about a South Carolina Form 1099-K requirement.

The federal test, for comparison: the IRS says a payment app or online marketplace must send a Form 1099-K when payments for goods or services total over $20,000 in more than 200 transactions, and adds: "However, they may send you a Form 1099-K with lower amounts and/or transactions." (Understanding your Form 1099-K, reviewed ). The Instructions for Form 1099-K count both parts for the calendar year, through each platform separately, and say the box 1a gross amount is figured without adjustments for credits, discounts, fees, refunds or shipping, so a 1099-K figure is not the same as profit. More on the federal rule in Form 1099-K for resellers.

Worked examples

State tax on a $40 marketplace sale to Columbia

At the 6% state rate, a $40.00 taxable item carries $2.40 of state tax, plus local sales tax for the delivery location. The facilitator remits it.

Same seller, two channels

A seller in Greenville sells $9,000 through marketplace facilitators and $3,000 from its own website to South Carolina buyers. The facilitators remit on the $9,000. The Department's FAQ says a South Carolina seller selling through its own website needs a retail license and remits tax on orders shipped to South Carolina; the 6% state rate alone on $3,000 is $180.00, before local tax.

Edge cases and details

  • A facilitator remits tax regardless of whether it or a third party delivers the products, the policy manual says.
  • Information Letter #19-14 says a facilitator may or may not receive compensation for its services and still be a marketplace facilitator.
  • Accommodations carry a 7% state rate rather than 6%, according to the policy manual's rate table.
  • The Department's FAQ treats a store selling another person's goods on consignment as the retailer responsible for remitting the tax: in its example, a store selling a jewelry maker's pieces remits even though it does not own them, and the FAQ adds that consignment sales include sales by marketplace facilitators.

What to do

  1. If every South Carolina sale goes through marketplace facilitators, keep the Department's FAQ answer and your marketplace sales reports with your records.
  2. If you also sell direct to South Carolina buyers, read the Department's FAQ on retail licenses and check with a tax professional.
  3. For remote seller thresholds, the Department points to SC Revenue Ruling #18-14 on economic nexus.

Common questions

Do I need a South Carolina retail license if I only sell on marketplaces?

No, according to the Department. A person whose products are sold only through marketplace facilitators is not a South Carolina retailer, regardless of nexus, and is not required to obtain a retail license.

April 26, 2019, when Act No. 21 of 2019 was enacted, according to Information Letter #19-14.

Does South Carolina have its own 1099-K threshold?

The Department of Revenue documents we checked say nothing about a South Carolina 1099-K rule.
