I just found this thread because my March Sales Tax liability report was wrong for the first time today. Luckily we don't have many complex tax situations and I run a little spreadsheet to verify the proper amount of tax, but it was definitely off, and it didn't include one customer that was non-taxable, which threw off my gross total & non-taxable amounts. "transactions without tax lines".  Hopefully this will be resolved before April's taxes are due in May.
