How do you add multiple VAT rates in QBO depending on who you are selling to?

Thanks for dropping by here in the Community, @morganjamesjewel. 

You can add multiple VAT rates, by going to the Tax Centre. Before doing so, the rates are provided for informational purposes, are not tax or accounting advice, and we recommend you consult your tax or accounting advisors regarding the applicability of these rates. Please follow the outlined steps below:

1. In the Tax Centre, select Add Tax.
2. Choose which type of tax rate you want to set up.
3. Enter the details of your tax rate. If you need help with this screen, select the help button (yellow question mark).
4. Select Save when finished.

Also, you can group your taxes, please note that once created they can't be edited or deleted. Here's how:

1. In the Tax Centre, select Add Tax.
2. Select "Group Rate" and then select Next.
3. Enter the Group Name and Description.
4. Select the Tax Rate and where it applies to Net, Tax, or both.
5. Select Save.

Additionally, QuickBooks Online offers customers in some countries the ability to deactivate tax rates if you no longer use them or it's not applicable for you.

1. In the Tax Centre, use the side arrows to find the tax you want to deactivate.
2. Click on Edit tax in the top right corner.
3. Click on Edit rates.
4. Click the green toggle option.
5. For custom rates - Under Action, click Edit and then click Make inactive.
