Frequently Asked Questions

How do I calculate sales tax?+
Sales tax = Price * (Tax Rate / 100). For example, a $50 item at 7% tax: sales tax = 50 * (7/100) = $3.50, total = 50 + 3.50 = $53.50.
How do I remove sales tax from a total?+
Pre-tax price = Total / (1 + Tax Rate/100). If the total is $107 at 7% tax: pre-tax price = 107 / (1 + 7/100) = 107 / 1.07 = $100.
Which states have no sales tax?+
Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Note that local jurisdictions may still impose their own sales taxes.
