Good Day, I would like to turn off VAT On QuickBooks Online South Africa.

Thanks for dropping by, avwiggill-vodama.

I know how important it is to have control over your VAT preferences, However, once we turned on the VAT feature, the option to turn it off is unavailable in QuickBooks Online.

I'd suggest submitting feedback within your QuickBooks Online (QBO) account. This way, it goes to our product developers to help improve your experience while using the program. Here's how. 

1. Go to the Gear icon at the upper right and select Feedback under Profile.
2. Enter your comments or product suggestions. You can also attach a screenshot or file to combine them all. 
3. Click Next.
   
4. You'll be provided a list of suggested help articles related to your comments. You can read through them or choose Skip and send message.
5. Select the appropriate category from the drop-down menu.
6. Tap Send message.

I'll be adding these help articles below to give you more insights about how VAT works in the system and all the things that you need to know once you're registered:

Set up sales GST/VAT rates and use them on forms.

The Value-Added Tax (VAT) registered.

Let me know if there's anything else that you need with QuickBooks. I'll be around to lend a helping hand. Have a good one!
