Hi Beverly, welcome to the Community.
You can add tax rates from the VAT section to set up a reverse charge tax code.
Please note that before setting up a new tax code in QuickBooks Online (QBO), you need to ensure that VAT has already been set up in your account.
Once that's confirmed, here's how you can set up a reverse charge tax code:
- Go to VAT.

- Click the Edit VAT dropdown and select Edit rates.
- Hit the Add tax rate button.

- Enter the necessary information needed.
- Click Save.
To ensure the reverse charge tax code is accurately configured and complies with applicable tax laws, I recommend consulting a tax specialist. They're best suited to guide you on proper tax setup and to meet regulatory requirements.
