You'll want to remove the tax rates if it wasn't processed yet. Let me show you how. Here's how:
From the left menu, select Taxes .
Select Edit VAT, then choose Edit Rates.
Find the tax rate you want to deactivate, then switch it from On to Off.
Once done, you can submit a new VAT return to HRMC again. If this is already process, I'd suggest getting in touch with our customer care support. A chat or phone agent has a specific tool to check on how to change your tax codes on the paid VAT. Here's how:
Click Help inside QuickBooks Online.
Select Contact Us.
Enter a brief detail about your concern, then click Let's talk.
Select either Get a callback or Start a chat.
Please know we're just right here to help you if you have other concerns.
