Looking at some TAX issues

I have had a look at the VAT issue an old issue from MM4, I am going through
my original emails to the forum from my 1st experiences. one of the 1st
issues was that VAT on products is defaulted to 17.5%. I have been adding
categories ect and prods to change layout ideas. It was when I went to
import a whole group of products into the standard MM5 that I noticed there
is no VAT rate in the imort option, O.K with mySQL it will be simple, but
what about those using mivaSQL, where is the option or have I missed
something here.
