Historic VAT RETURNS after switching to Quickbooks?

Hello there, NitinUpadhyaya. 

Thank you for posting on the Community page. I'm here to guide you on how to import or record all the transactions within the VAT return that has the refund.  Then, we can change the VAT settings' Effective Date to pull up the return.

Here's how:

1. Go to the Taxes menu and click VAT. 
2. At the upper-right, click Edit VAT and then Edit Settings. 
3. Change the Effective Date for a new scheme to the date you filed the return. 
4. Click Save. 
5. Under the Filed returns section, the reports will then show up.
6. Click Record payment. 
7. Once done, click Save. 

I have a link here that you can check on how to prepare VAT exceptions and reports in QuickBooks Online.

Get back to us if you have other questions about your account. We're always here to help. Take care!
