We have clients that use levies for precisely that - multiple sales tax
rates - consisting of a state rate, combined with various local or
county tax rates, all based on zip code. Basically you could have as
many rates as you have zip codes. It sounded to me that is precisely
what DB was looking for.

The levy rates can be controlled by zip code, or criteria other than zip
code... I assume you will have some means of identifying the location of
the customer in order to assess the tax...
