I typed the wrong vat number how do I correct it on the app

Hi there, @johnbardiniltd-l. I'd be glad to help edit your VAT number right away.

QuickBooks Online (QBO) mobile app allows us instant access to your QBO data from your mobile device. However, there are some limitations when using the mobile app. Not to worry, you can still edit your tax info using a web browser on your device. It works the same with how you access your account on your computer. 

Here's how:

1. Sign in to your QuickBooks Online account.
2. Go to Taxes.
3. Select the Edit VAT dropdown arrow.
4. Choose Edit settings 
5. Edit your VAT registration number.
6. Click Save.

I'm also linking these articles that you can read and learn about VAT:

• Set up and edit VAT settings, codes, and rates
• Common VAT codes 

Fill me in if you have more questions about handling taxes in QBO. I'd be glad to help you achieve your goals.
