Hi there,
Keeping your books accurate is a good way to stay ahead with your work. I'd be happy to share more information about filing past due sales tax in QuickBooks Desktop.
Since this action affects previously closed periods, I recommend contacting an accounting professional to get more info on recording the transactions. Doing this will help prevent any future discrepancies in your books. If you're not in contact with one, I encourage you to search for one on our website using this link here. Let me know if you have other questions. I'm here to help.
