This is not a new problem. I think I reported it before but can't find it.
 
We have some jurisdictions with multiple (no more than two, thankfully!) tax authorities. Everything works fine as far as charging it and the right liabilities being recorded, but either AR-K does not report correctly, or I don't have something set up right.
 
AR-K reports each Tax Code individually, PLUS the amount for the total Group.
 
For example:
Tax Group VT-BUR has Tax Codes VT and VT-BUR.
We make a sale of $1000 to someone with Tax Group VT-BUR.
The report shows $1000 under VT PLUS $1000 under VT-BUR, for a total of $2000.
 
So I have to add up all the amounts in the subgroup codes and deduct that amount from the Total. Of course, I can't really do anything with it, I just add all the Totals together to compare to my Crystal Report since the Non-Taxable Freight is also not recorded properly... see http://www.istechforum.com/YaBB.pl?num=1200577460
