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:

1. Go to VAT.
   
2. Click the Edit VAT dropdown and select Edit rates.
3. Hit the Add tax rate button.
   
4. Enter the necessary information needed.
5. 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.
