Frequently asked questions
How do I calculate sales tax?
Multiply the price by the tax rate as a decimal. At 8.25%, a $40 item has $40 × 0.0825 = $3.30 tax, so the total is $43.30.
How do I take sales tax out of a total?
Divide the total by 1 plus the rate. A $54.00 total at 8% is $54.00 ÷ 1.08 = $50.00 before tax, so the tax was $4.00.
Why is my receipt rate different from the state rate?
Counties, cities and special districts add their own tax on top of the state rate, so the rate depends on where you buy.
When to use Sales Tax Calculator
Before a big purchase, when pricing products for a shop, checking a receipt, or splitting tax out of expenses for your records.
