Formula
Statewide sales tax on a price is the price times 4.225 divided by 100. This page does not add a city or county rate on top.
City and county tax is extra, so the amount at the register can be higher.
Removing sales tax uses the same statewide rate. Divide the tax-inclusive price by 1 plus the rate. Local tax is still not part of that figure.
Add: tax = amount × rate / 100. Remove: net = amount / (1 + rate / 100).
- amount The price you type.
- rate The Missouri statewide rate, 4.225%. It is fixed on this page.
