How do I figure out why my sales tax liability report changed after the month ended?

Sales tax liability report data depends on how you enter transactions in QuickBooks Online, @Tim-Swett1.

If your July revenue increased after filing your sales tax, check for transactions that were added or edited for that period after the month ended. You can run a Sales Tax Liability report and compare it with the previous data that you have filed.

Here's how:

1. From the left menu, hover your mouse over Reports and select Standard reports.
2. Enter Sales Tax Liability Report in the search box.
3. Ensure that you select Custom in the Report period and choose the exact period for the one you have already filed.
   
   
    
4. Drill down by clicking the amount of a certain state where you found the difference.
   
   
    
5. Find the edited or the added transaction.

Make the necessary changes if you need to, but I recommend consulting an accountant to ensure accuracy with your books.

If you want to find out who made the changes, you can check the Audit Log and look for the edited or added transactions.
