Who must register for North Carolina sales tax
You must register for a North Carolina Certificate of Registration if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $100,000 in annual sales or 200 or more separate transactions into North Carolina in the current or previous calendar year, or;
- Has a physical presence in North Carolina, such as an office, employee, warehouse, or inventory stored in the state.
North Carolina's dual threshold means you must register once you cross either the dollar amount or the transaction count, whichever comes first.
Once you exceed the threshold, you should register before making further taxable sales in North Carolina. If you're unsure whether your business has nexus, see the North Carolina Sales Tax Guide for a broader explanation.

What happens after registration
After registering, you must begin collecting North Carolina sales tax on taxable sales and file returns based on your assigned filing frequency.
North Carolina taxes digital goods and SaaS. Both are considered taxable tangible personal property or digital property under state law, so sellers of software, subscriptions, and downloadable content must collect sales tax on those sales. See the North Carolina Sales Tax Guide for details on taxability.
Local county add-on rates are administered centrally through the state. You do not need separate county registrations. All local tax is reported and remitted on the same state return.
