North Carolina Sales & Use Tax — E-500 Return

Determine whether the business has physical or economic nexus in North Carolina. NC's economic nexus threshold is $100,000 in gross sales OR 200 separate transactions in the prior or current calendar year. Confirm the business is registered with NCDOR via the online Business Registration portal before attempting to file.

Identify the correct filing frequency assigned by NCDOR — monthly (>$100 average monthly liability), quarterly, or annual — and pin the exact reporting period. NC is an SST full member, so sourcing is destination-based; confirm the filing period end date and due date (typically the 20th of the month following the period).

Classify all sales transactions by taxability under NC law. Apply the 4.75% state rate plus the applicable county local rate (2.00%–2.75%, max combined 7.50%). Key NC-specific rules: grocery food is exempt from state tax but subject to the 2% local rate; SaaS is not taxable; canned/downloaded software and digital goods are taxable; professional services are not taxable; manufacturing equipment qualifies for an exemption refund program; prescription drugs are fully exempt.

Identify purchases on which NC sales or use tax was not collected at point of sale — including out-of-state vendor purchases, online purchases, and business equipment — and compute the compensating use tax owed at the same combined rate applicable to the business's NC location. Manufacturing equipment may qualify for the refund program rather than direct exemption.

Complete NCDOR Form E-500 with total gross sales, taxable sales, state tax, local tax by county, use tax, any credits or prior overpayments, and net tax due. File electronically through the NCDOR online portal (ncdor.gov) by the due date. Remit payment via ACH debit or credit card. Retain all supporting schedules and exemption certificates for four years per NC record-keeping requirements.
