Hello there, @BOL-2188.

You can directly add and post this tax transaction on your tax account register. To do so, please refer to these steps:

1. Navigate to the Transactions menu.
2. Click Banking.
3. From the For Review tab, click the tax transaction.
4. In the Category field, choose your tax account.
5. Select Add.

I've added this helpful article for your reference: Categorise and match online bank transactions in QuickBooks Online.

Also, to guarantee that your bank balance and QuickBooks are matched, you need to reconcile your account regularly.
