This is happening to me as well. I just went through my long list of products and services and changed all of the service items back to non-taxable but that is not helping me get my sales tax paid by tomorrow. I know it's last minute but this whole process should only take me 15 minutes. The math on the Sales Tax Report isn't even correct. No matter what amount is showing in the Taxable Amount X 6% is giving the same answer. $5 X 6% does not equal the same thing as $10,000 X 6%. To avoid penalties am I supposed to just pay what I GUESS is correct??
