Where can sales tax rates by zip code be searched for?

Avalara SalesTax and zip-tax websites offer free sale tax rates searches by zip code. Tax Data Service is another site that offers a sales tax lookup, by zip code as well as by specific address.

On the Avalara SalesTax site, users enter any zip code to see the exact sales tax for that area. Avalara also offers a calculation of total tax when a price and number of items are entered and a tax breakdown by jurisdictions when a free account is set up.

The zip-tax site provides a detailed breakdown of a specific zip code's sales tax rates, including state, city and district taxes if applicable. Tax Data Service also lists out specific jurisdiction tax amounts for any zip code entered.
