Well, the short answer would be that you need to edit your tax tables to implement the tax regimes you need (I assume that we talking about the integration between Adagio Payables and Purchase Orders for Adagio).
But as to the specifics, we refrain from giving sales tax setup advice on the forum, as this is highly specific to the way (and where) a company does business. In this case, I'd recommend using the service of an Adagio reseller who is familiar with both you business, and the modules you are trying to configure.
