I've been using QBO for about a year and sales tax calculation from my Square transactions has always "just worked." But this month when I tried to file my sales tax report, QBO tells me I have no tax due. If I view the tax liability report for the month (2/1/25 to 2/28/25) not a single transaction from Square has an amount in the "Taxable Amount" column. The tax rate and tax authority name are correct, and I know Square calculated tax correctly (checked in the Square dashboard). 

The interesting thing is if I extend my tax report to the previous reporting period (1/1 to 1/31), when everything "just worked", I see a taxable amount and tax collected for each of the receipts. Then suddenly, once it turned to February, taxing seemed to stop. If I drill down to a receipt from February, none of the transactions for that day have the "Tax" checkbox checked. Conversely, all the receipts from January have the check box checked. I suppose I could manually check each transaction from each receipt for the month, but that doesn't seem sustainable. Any ideas?
