Frequently asked
Why can one ZIP code have several sales tax rates?
ZIP codes are postal routes, not tax jurisdictions. A ZIP can straddle a city boundary or two counties with different local rates. The pages here cover ZIPs that lie at least 60% inside a city and use that city's published rate; for the rest, use the state's address lookup linked in the result.
Which ZIPs are covered with an exact rate?
1,352 ZIP codes inside 40 cities, from New York and Los Angeles to Honolulu. Every other ZIP gets the state rate plus the average local rate, clearly labelled as typical.
