Frequently asked questions
How do you calculate sales tax?
Multiply the pre-tax price by the tax rate as a decimal. At 8% on a 50.00 item, the tax is 50 x 0.08 = 4.00 and the total is 54.00.
How do I take tax out of a total?
Divide the total by 1 plus the rate as a decimal. If the total is 54.00 and the rate is 8%, the pre-tax price is 54 / 1.08 = 50.00.
What sales tax rate should I enter?
Use the combined rate where you buy, including state, county and city parts. Your receipt or your local tax authority shows the correct figure.
Is sales tax the same as VAT?
They work differently. Sales tax is charged once at the final sale. VAT is charged at each stage of production and sale, though shoppers usually see one VAT-inclusive price. This calculator also works for a VAT-inclusive price if you enter the VAT rate.
