How this tool works
Sales tax equals taxable price × tax rate; tax-inclusive mode separates the tax already contained in the entered total.
Limits to know
The tool uses only the rate and tax treatment entered. It does not look up current state or local rates, product exemptions, sourcing rules, holidays, or filing obligations.
