Our restaurant uses another company POS system (Lavu), which is connected through the Square Stand/Square reader as we use Square as our payment processor. The Lavu POS system adds the sales tax to the customer check, so when the credit card payment is run, only the total check amount (including sales tax) is communicated over to Square. That's perfect for charging the card, but it also means that my Square transaction reports show the entire amount as gross sales and shows $0.00 for sales tax. Therefore I am trying to reconcile my 1099-K totals for the year with my Lavu POS transactions, so that I can provide the correct sales tax documentation to my accountant for offsets to the 1099-K. Since Square uses UTC transaction time, but no easy way to identify which of my 2018 transactions are excluded from the 1099K, it is proving to be quite a project. Is anyone else in the same boat, and how do you deal with it?
