Rates and vendor guides for all 50 states and D.C.
Base state sales tax rates for all fifty states and Washington D.C., with a page for each covering how the tax is calculated there, a worked example at that rate, and what craft fair and market vendors need to know before selling.
5 states have no statewide sales tax at all: Alaska, Delaware, Montana, New Hampshire, Oregon. Of the rest, the highest base state rate is California at 7.25% and the lowest is Colorado at 2.9% — though local add-ons mean the rate you actually charge at a market can differ substantially from the state figure.
The rate that applies to a sale is the combined rate where the sale happens — for a vendor, the event venue. Find your state below, check whether local rates apply on top, then run the numbers with the sales tax calculator. If you price tax-inclusive, the reverse sales tax calculator extracts the tax back out at the end of the day.
