North Carolina imposes a statewide base sales tax of 4.75% on the retail sale of tangible personal property and certain digital goods and services. Every county adds at least 2% on top of that, so the combined rate most North Carolinians encounter at the register is 6.75% to 7.5% depending on where the purchase takes place. This calculator handles both directions: start with a pre-tax price to find the total, or start with a receipt total to find the pre-tax amount — with a complete line-by-line breakdown of state tax, local tax, and combined tax.
How the North Carolina sales tax system works
North Carolina has a two-tier sales tax structure. The state rate of 4.75% applies uniformly across all 100 counties. On top of that, each county levies its own local rate — typically 2.00% to 2.25% — giving most shoppers a combined rate of 6.75% to 7.00%. Some counties with voter-approved transit or special-purpose taxes layer on an extra 0.25% to 0.50%, with Durham and Mecklenburg at the higher end. The resulting combined rates range from 6.75% (Wake, Guilford, Onslow) up to 7.50% (Durham).
The state administers both the state and local portions through the North Carolina Department of Revenue (NCDOR). Retailers collect the combined rate at the point of sale and remit the full amount to the NCDOR, which then distributes the county share back to each jurisdiction.
Calculator modes explained
Add mode is for shoppers working out what a purchase will actually cost. Enter the sticker price; the calculator multiplies it by the combined rate, shows the state tax portion, the local tax portion, the total tax, and the final total with tax.
Remove mode is for anyone who sees a total on a receipt and needs to work backwards — to find the pre-tax price for expense reporting, accounting reconciliation, or checking a retailer’s math. The formula used is:
Pre-tax = Total ÷ (1 + combined rate)
The tax is then the difference between the total and the pre-tax amount. State and local portions are split pro-rata from the combined rate.
Worked example — Wake County
Wake County (home of Raleigh) applies the state 4.75% plus a 2.00% county rate, for a 6.75% combined rate.
| Item | Value |
|---|---|
| Pre-tax price | $250.00 |
| NC state tax (4.75%) | $11.88 |
| Wake County tax (2.00%) | $5.00 |
| Total tax (6.75%) | $16.88 |
| Total with tax | $266.88 |
Reversing a $266.88 receipt: $266.88 / 1.0675 = $250.00 pre-tax, confirming $16.88 in tax.
Worked example — Mecklenburg County
Mecklenburg County (Charlotte) has a 2.50% local rate including a transit tax, giving a 7.25% combined rate.
| Item | Value |
|---|---|
| Pre-tax price | $500.00 |
| NC state tax (4.75%) | $23.75 |
| Mecklenburg local tax (2.50%) | $12.50 |
| Total tax (7.25%) | $36.25 |
| Total with tax | $536.25 |
Note: North Carolina’s state rate is 4.75% (NCDOR 2025). The typical combined rate across the state is approximately 6.75%–7.50% when county taxes are included. Always verify your exact county rate at ncdor.gov, as local transit and special-purpose rates can change with ballot measures.
