Can I undo my filed VAT?

Thanks for posting your taxes concerns in the Community, @accounts-belanet.

In QuickBooks, we're unable to undo the tax filing. However, you can email our Care Support Team to unfile the filed tax return for you.

Please have your QuickBooks Online Company ID handy, and the tax filing period you want to undo for a faster transaction.

You can go to the Gear icon to see your Company ID under Billing and Subscription in Account and Settings.

Here's how to email our support:

1. Go to the Help icon on the upper right.
2. Click Contact Us, then enter "Unfile tax return" and then hit Let's talk.
3. Choose to Start an email

I've got this article as your reference for the South African new rate: VAT Feature Update FAQ.
