Work out sales tax by rate instantly with clear inputs, formula shown and shareable results.
Sales tax is often layered: a state rate plus one or more local rates that apply to the same base. Adding the rates before applying them gives the same answer as applying them in sequence, since neither taxes the other.
Combined sales tax
Tax = price × (state rate + local rate)
Tax figures are estimates based on the rates, caps and thresholds you enter. Real rules differ by jurisdiction and change every year, and personal circumstances alter the outcome. This is not tax or financial advice — confirm with a qualified adviser.
Not in a normal sales tax; both rates apply to the same price. Some special districts differ.
Local jurisdictions set their own add-on rates, so the total can vary within a single city.
