Calculating sales tax in North Carolina involves understanding both the state's base rate and any applicable local taxes. This calculator helps you accurately determine the total sales tax for your purchases and the final price.
How North Carolina Sales Tax Works
North Carolina imposes a state sales tax on tangible personal property and certain services. In addition to the state rate, most counties in North Carolina levy a local sales tax. The combined rate is what you typically pay at the point of sale.
State Sales Tax Rate: The general state sales tax rate in North Carolina is 4.75%.
Local Sales Tax Rate: Most counties add a local sales tax. This rate can vary by county but is often 2.00% (0.50% for county and 1.50% for transit). The combined local rate is typically 2.00%, making the common total rate 6.75% (4.75% + 2.00%).
Total Combined Rate: The sum of the state and local tax rates.
The Calculation Formula
The sales tax is calculated on the purchase amount. The formula is as follows:
Total Tax Rate (%) = State Sales Tax Rate (%) + Local Sales Tax Rate (%)
Let's say you are purchasing an item in Charlotte, North Carolina (Mecklenburg County).
Purchase Amount: $150.00
North Carolina State Sales Tax Rate: 4.75%
Mecklenburg County Local Sales Tax Rate: 2.00% (This is the typical local rate for Mecklenburg, which includes county and transit taxes)
Total Combined Tax Rate: 4.75% + 2.00% = 6.75%
Using our calculator:
Sales Tax Amount: $150.00 × (6.75 / 100) = $150.00 × 0.0675 = $10.13 (rounded to the nearest cent)
Total Cost: $150.00 + $10.13 = $160.13
This calculator uses the standard state rate of 4.75% and a common local rate of 2.00%, which together make the prevalent 6.75% total rate in many NC areas. You can adjust the local rate if you know a specific county's or city's rate differs.
