It's my pleasure to help you with your VAT, JFquick.
Since your VAT number is unavailable, you can turn off the Default tax rate selection in Account and Settings in the meantime so you can create an invoice successfully without asking for the VAT number.
Here's how:
- Go to the Gear icon.
- Select the Account and Settings.
- Click Advanced, then select the Pencil icon in Accounting.
- In the Default tax rate selection, click the Exclusive of Tax dropdown.
- Select No VAT.
Another way to avoid the prompt message when creating an invoice is to select No VAT (0%) from the dropdown in the VAT column.
Afterward, when you're done registering for your VAT number, you can edit the tax code to the correct one. You can check this complete guide here to learn more about the VAT: VAT codes in QuickBooks Online: A complete guide.
