Sales tax in both directions
Enter a price and your combined sales tax rate to see the tax and the total you'll pay. Have a receipt total and need the pre-tax price? Choose Remove tax — the calculator divides by (1 + rate) instead of subtracting the percentage, a common mistake that gives the wrong answer.
In the US, your rate is the state rate plus any county, city and special-district taxes, so check the combined rate for your ZIP code. The same calculator handles VAT in the UK and Europe and GST in India, including the CGST/SGST and IGST split for invoices.
