If your business makes sales to customers in South Carolina, you may be responsible for collecting and remitting sales tax to the state. Whether or not you need to do this depends largely on whether you have a substantial physical presence, or nexus, in the state, as well as whether or not what you’re selling is subject to sales tax under South Carolina laws.

South Carolina Sales Tax Rates

The state sales tax rate in South Carolina is 6%. Counties and municipalities can impose additional sales tax locally as well, with the maximum rate in the state currently 9% in Charleston. You can review a complete list of sales tax rates in South Carolina by municipality on the South Carolina Department of Revenue website.

If you have a physical location, and the customer purchases an item in person and takes it with them on the spot, you will charge the rate applicable at that location. If you are shipping goods to customers in South Carolina, the rate you will need to charge is usually based on the final destination of those goods, regardless of whether they originate from inside or outside the state.

A buyer who is 85 years old or older may claim a 1% exemption from state sales tax, provided that the purchase is made for his or her personal use. Proof of age must be provided at the time of the sale.

Nexus Requirements in South Carolina

South Carolina considers a business to have a tax nexus in the state if it meets one of several main conditions or a combination of other conditions. Although the specific details can get somewhat complicated for special situations, most businesses will meet or not meet some of the main general requirements. These include:

  • Having an office or other real property in South Carolina
  • Having employees in the state
  • Keeping goods in a warehouse in the state
  • Marketing actively to South Carolina customers
  • Having a company representative who visits the state four or more times a year

One significant element to keep in mind is that there are several Amazon fulfillment centers in South Carolina. If Amazon fulfills your sales and you sell to customers in South Carolina, your goods are likely stored in one of these warehouses, thereby creating a nexus in the state for your small business. Although there may still be some ambiguity surrounding this arrangement, any substantial sales that proceed in this way will likely be looked on by the state as taxable sales, so you should register to collect sales tax in South Carolina if this applies to you.

In addition to physical nexus considerations, South Carolina’s economic nexus law requires remote sellers who make $100,000 or more in gross sales of tangible personal property per year to register to collect and remit sales tax. 

It’s also important to note that nexus determinations are made on a fiscal year basis. So, if you have a nexus for any part of the fiscal year, you should collect sales tax on any purchases made during that time frame, even if you no longer meet the nexus requirements by the end of the period in question.

What Is Taxable in South Carolina?

In general, sales of tangible personal property are subject to sales taxes in South Carolina. Most services, on the other hand, are not unless they involve the production of a tangible good. Installation charges associated with purchasing tangible personal property are not taxable if listed separately on the bill, while set-up charges are taxable in similar situations.

Most groceries are not taxable, and this encompasses any food meant to be taken home and consumed. Items like beverages, snacks, and seasonings are included here, but hot, ready-to-eat foods are not. Other excluded items are:

  • Foods meant to be heated in the store
  • Hot or cold food to be eaten in the store at a lunch counter or other dining area
  • Over-the-counter medications
  • Vitamins
  • Pet food
  • Prepared foods
  • Tobacco
  • Hot, ready-to-drink beverages
  • Alcohol

Exceptions to the tax on prepared food items apply if these meals are served in a facility that cares for elderly or disabled persons, or when sold to certain non-profit organizations that have previously obtained a sales tax exemption certificate from the state. It’s also important to note that these exceptions and exemptions apply to the state sales tax, but local government tax rates may still apply depending on the regulations in the specific municipality.

Although most services are not taxable in South Carolina, there are certain taxable categories. These include furnishing accommodations, providing electricity, laundry and dry cleaning services, and most communication services.

Registering to Collect South Carolina Sales Tax

If you have a nexus in South Carolina and sell a taxable good, you must register with the state to collect and remit that tax before you start making sales. You can do this by visiting the Department of Revenue website and filling out the online form. The cost to register is $50.

To complete the registration process, you will have to provide certain details about your business, including but not limited to:

  • Business name and type
  • Physical address and mailing address
  • Federal Employer Identification Number or Social Security Number
  • Contact Information
  • Description of business activities
  • Date you plan to begin selling in the state

Other information may be required as well based on the nature of your business and your specific situation.

Filing and Payment Deadlines and Penalties

The frequency with which you’ll have to file your South Carolina state sales tax returns will depend on your average monthly tax liability. You may file annually if that average is between $0 and $16.66. Quarterly filing is required for an average tax liability of $16.67 to $100, and monthly filing is required if your monthly tax liability is over $100 on average.

Failing to file a sales tax return once you’re registered to collect sales tax in South Carolina can result in a fine of 5% of the tax due if the return is filed within one month of the due date. An additional 5% will be added for each subsequent month, up to a maximum of 25%. If you file a return on time but are late with the payment, you’ll face a penalty of 0.5% for each month the payment is late.

South Carolina does require all registered businesses to submit zero returns for periods in which no sales tax was collected. Penalties will also apply if you fail to file this type of return.
