Sales Tax Rate Databases by State:

NOTE:  These are destination “sales” tax rates, not “use” tax rates or “seller’s use” tax rates.  So be aware:  If you’re shipping goods from one state to another, the local rates may/may not apply to your transaction.  Further, if you’re shipping intra-state, be sure you’re in a destination-based taxing state.  Origin based taxing states are generally all taxed at your business ship-from location. (if you need more information about this, leave a comment and we’ll reply).

Alabama – search by City or County name.  Additionally, under the search you can pull up City and County listings as well as a downloadable text file of all the rates.  Or, if you prefer, you can see all the tax rates in AL in this PDF file. 

Alaska – local taxes.  Click on the excel file 1/4 way down the page.  Or click on this PDF file and go to page 13. 

Arizona – lookup by County or City; AZ state collects for most of thier cities/counties.  There are 14 cities that have other rates not published on the AZ page because they separately collect their own sales taxes (a.k.a. “Non-Program” Cities).  A list of them and their contact info can be found here and it looks like this website is keeping up the rates sufficiently for these “non-program” cities.  A comprehensive listing of all city and counties in AZ with total tax rates given can be found in this PDF file.
