I've got some information for you, @hein.

You can use the Out of the scope of Tax option as the default tax rate in your Account and settings. This way, you don't need to select a VAT when creating a transaction.

Here’s how:

1. Open your QuickBooks account.
2. Select the Gear icon, then go to Account and settings.
3. Click Advanced.
4. Press the Pencil icon in the Accounting section.
5. Select Out of scope of Tax.
6. Click Save after.
