Hello there, @rst123!
The available reports you can pull up depends on how you record your sales transactions. If you have a record of them inside QuickBooks, you can pull up your VAT Liability report. This report will show you the amount of taxes you owed to the agency.
- Go to Reports.
- Scroll down the page to the Manage VAT category of your reports.
- Click VAT Liability Report.
But if your sales transactions are recorded through your third-party seller, you'll have to contact their Technical Support so you can pull up a report already categorise with VAT or zero-rated products.
Lastly, here's a few articles you can read to learn more about your VAT and other related tasks: VAT for QuickBooks Online.
If there's anything else that I can help you with, please let me know in the comments down below. I'll be happy to help.
