As an insight, the system will only allow you to track taxes on the expense, checking, and income accounts. However, using the Accounts Payable or Accounts Receivable type of accounts isn't applicable.

For future reference, I've got you some links that will help you learn about adding and removing the VAT rates or sales taxes on your forms in QBO:
Feel free to message again if you have additional questions. I'm always delighted to help.
