What is Nexus?

You'll need to collect sales tax in South Carolina if you have nexus there. There are two main ways that sellers can be tied to a state when it comes to nexus: physical, or economic.

Physical nexus means having enough tangible presence, or activity in a state to merit paying sales tax in that state.

Economic nexus means passing a states' economic threshold, for total revenue, or the number of transactions in that state.

Calculating Nexus in South Carolina

Physical Nexus

Physical nexus is all about your physical footprint in the state. If you have an office, warehouse, store, or even inventory stored within South Carolina, you've established a physical nexus.

Economic Nexus

Economic nexus looks at your sales volume. It's triggered if you exceed:
  • Over $100,000 in gross sales in South Carolina within the current or previous calendar year, covering both physical and digital products/services.
  • 200 or more separate transactions in the state, within the same timeframe.

Affiliate Nexus

Affiliate nexus is about your business connections in the state. It occurs when an in-state affiliate helps promote your sales. This can be through various activities like customer support, sales solicitation, or handling returns and exchanges. However, simply advertising or linking to your website doesn't create an affiliate nexus – there needs to be more substantial involvement.

Click-Through Nexus

South Carolina doesn't have click-through nexus laws. These laws typically involve agreements with in-state affiliates to direct customers to your website, but that's not a factor here.

Marketplace Nexus

Marketplace nexus comes into play when a marketplace facilitator handles sales for a remote seller without a physical presence in South Carolina. The key points are:
  • The facilitator deals with tangible goods or services delivered to South Carolina.
  • The remote seller must have over $100,000 in gross sales from South Carolina buyers within a year.
  • If these conditions are met, the facilitator is responsible for collecting and remitting sales tax for the remote seller.
For example, if a facilitator aids a California-based remote seller with over $100,000 in sales to South Carolina customers, the facilitator must handle the sales tax. But if the sales are under $100,000, they don't need to collect and remit the tax.

Guide to collecting sales tax in South Carolina

Is South Carolina an Origin or Destination Sales Tax State?

Think of South Carolina as playing by destination rules in the sales tax game. This means you charge sales tax based on where your customer is, not where your business is located. So, if you're selling something from Spartanburg to a customer in Charleston, you'll apply the Charleston sales tax rate.

What Sales are Subject to Sales Tax in South Carolina?

South Carolina requires sales tax on a wide range of items. This includes tangible goods like furniture and electronics, as well as some services. If you're ever unsure whether your product or service is taxable, it's a good idea to check with the South Carolina Department of Revenue (SCDOR).

Is Software as a Service (SaaS) Taxed in South Carolina?

Yes, Software as a Service (SaaS) is taxed in South Carolina. The state considers SaaS to be tangible personal property, so if you're offering SaaS, you need to collect and remit sales tax for sales in the state. This applies to all types of SaaS, whether it's a temporary access or a download. Custom software, however, remains exempt.

What is Exempt from South Carolinane Sales Tax?

There are some exemptions to South Carolina's sales tax. Items like certain groceries, prescription medications, and agricultural supplies usually don't attract sales tax. Always verify with the SCDOR to see if your items fall into the exempt category.

Who is Eligible for South Carolina Sales Tax Exemptions?

Groups like nonprofit organizations, government agencies, and some wholesalers and manufacturers can get exemptions from sales tax. They just need to provide a valid exemption certificate.

What To Do If Your Customer is Exempt from Sales Tax in South Carolina?

When selling to a tax-exempt customer, make sure to keep a copy of their exemption certificate. This is your proof that the sale was exempt from sales tax, just in case the SCDOR checks in.

What if You Lose a South Carolina Sales Tax Exemption Certificate?

If you lose an exemption certificate, it's like misplacing your compass on a journey. But don't worry, just ask the customer who gave it to you for a new copy. It's important to have this on file.

Steps for Filing a South Carolina Sales Tax Return

How often you file and pay sales tax in South Carolina depends on how much tax you're collecting. It's a bit like watering plants: the more you have, the more attention they need.

Most businesses will file and pay monthly, quarterly, or annually. If you're collecting over $100 in tax, you'll likely file monthly. If it's less than $100 but more than $15, you'll file quarterly. And for those collecting under $15, annual filing is your path.
  • Monthly Filing: Initially set up for all accounts. Due by the 20th of the month following the reporting period.
  • Quarterly Filing: Available if your quarterly tax liability is $300 or less. Due on the 20th after the quarter ends (April 20, July 20, October 20, and January 20).

What If a Filing Date Falls on a Weekend or Holiday?

If a filing date lands on a weekend or holiday, no sweat. You get to file on the next business day, like a little extension.
