Use the Review Sales Tax Rates window to review your existing sales tax rates. Receivables creates these sales tax rates when you enter customer addresses in the Customers window. You can view the locations and associated rates for your customer addresses in the Tax Locations and Rates window. If you have a situation where locations are defined without rates and these locations are included in existing authorities, Receivables also creates sales tax rates when you assign rates to these locations.

If you update rates belonging to locations that are already included in an authority, Receivables automatically updates all of the sales tax rates that are associated to this authority. You can review the changes in this window.
The number of sales tax rates created for each authority depends upon the postal code and date ranges that you assigned to each location included in your authority.
