Sales Tax Nexus in North Carolina: What Online Sellers Need to Know

The Short Answer

North Carolina triggers sales tax obligations at $100,000 in annual sales — and as of July 1, 2024, the 200-transaction threshold was eliminated. Only the dollar threshold matters now. Marketplace sales count toward your total. North Carolina has a uniform county rate structure (every county adds exactly 2%) that makes rate calculations simpler than most states.

Economic Nexus Threshold

• Dollar threshold: Gross sales exceeding $100,000 sourced to North Carolina (previous or current calendar year)
• Transaction threshold: Eliminated effective July 1, 2024 (H.B. 228)
• Measurement period: Previous or current calendar year
• Original effective date: October 1, 2018

H.B. 228 (signed July 1, 2024) also explicitly clarified that marketplace-facilitated sales count toward the seller's $100,000 threshold.

Does North Carolina Count Marketplace Sales Toward Your Threshold?

Yes. North Carolina explicitly includes marketplace-facilitated sales when calculating your $100,000 threshold. This was clarified in the same H.B. 228 that removed the transaction count.

From the statute: the threshold applies to sellers with gross sales "exceeding $100,000 sourced to North Carolina... including sales as a marketplace seller and marketplace-facilitated sales."

The marketplace facilitator collects and remits tax on facilitated sales — so you're not double-paying. But those sales count toward whether you're required to register.

What Taxable Products Look Like in North Carolina

North Carolina's rate structure is notably clean:

• State rate: 4.75%
• County rate: Uniform 2% across all 100 North Carolina counties — every county charges exactly the same local rate
• Standard combined rate: 6.75% for most sales statewide
• Some counties: Have additional local levies (transit tax, etc.) — a few reach 7.25%–7.5%

This uniform county structure means you don't need address-level rate lookup for the county portion — it's always 2% on top of the state rate.

• Clothing: Taxable — North Carolina taxes clothing
• Groceries/Food: Taxed at a reduced 2% state rate (not the standard 4.75%). County rates still apply on top, so most grocery purchases carry about 4%–4.5% total. Groceries are not exempt — they're just at a lower rate.
• Certain digital property (downloads): Taxable since 2010 — North Carolina was one of the first states to tax downloaded digital goods (music, video, apps, e-books)
• SaaS: North Carolina's treatment of pure SaaS (cloud-only access) is a gray area. The "certain digital property" framework clearly covers downloads; purely remotely-accessed software is less settled.
