I'll be happy to shed light on how taxes are calculated in QBSE, Jody.
We can only enter sales receipts without VAT. However, QBSE calculates your VAT as you enter transactions, provided that you set up your tax profile.
Here are the articles that you can use as a reference for checking your setup and downloading your tax summary. These are useful for year-end tax filing. I'm sharing them with you in advance.
If you have questions in the future, you can always go back to this thread.
