So are you referring to the setup of the sales tax group below?  There is not an overpayment so I don't think that is the issue.  I just can't find anywhere in QB Desktop that explains the report itself.  When you are invoicing you would pick the Group Name: Pryor, Mayes, OK-GRP.  Then on the report it will have them listed separate. That is what is nice about the report in QBD it gives you the totals as compared to QBO.  But if your total is $1000 in net sales and as per my example above and you have $1000 in each line does QBD just know that the total is $1000 in total sales or does it have $1000 on each line then a Negative $2000 on the multiple tax line (subtracting the duplicate taxable amounts) which gives you your actual total of $1000.00 for the month....
