luckpandaHow to use the sales tax calculator
- Choose Add tax, or Price includes tax to work backwards.
- Enter the price.
- Pick the state, then add any local (county or city) rate.
- Read the sales tax and the total.
The sales tax formula
Sales tax = price × (state rate + local rate) ÷ 100. Total = price + sales tax. Working backwards, price before tax = total × 100 ÷ (100 + combined rate).
Example: a $250 order shipped to Chicago, Illinois. The state rate is 6.25%, and Cook County and Chicago add 4%, for 10.25% combined. Tax = $250 × 10.25 ÷ 100 = $25.63, total $275.63.

Do you need to charge sales tax?
You collect sales tax in a state where you have nexus: a physical presence, or, since the 2018 Wayfair decision, enough sales into the state (often $100,000 a year). Many services and digital goods are taxed differently from physical goods, and selling to a reseller with a valid resale certificate is usually exempt.
