Hello. I mistakenly filed the vat return and it is not correct . I should add some more input there. please help me to unfile the vat in quickbook.

Thanks for reaching out to us, pubaid813-gmail-.

I understand how critical it is to keep your VAT returns accurately. I'll route you with the best support to help you unfile your VAT return.

QuickBooks marks your tax return as filed once you have filed it. The option to delete or unfile it isn't possible in QuickBooks Online. Instead, you'll need to contact our QuickBooks Online Support team. They can request to delete the incorrect VAT return by submitting a VAT unfiling request. Please gather the following information before proceeding:

1. QuickBooks Online Company ID.
2. Which tax filing period do you wish to unfile.

You can contact the QuickBooks support team by logging into your QuickBooks company file, clicking the Help (?) icon in the upper right corner of the screen, and then selecting or typing Contact Support.

Please see this article for more information on the unfiling process: How to unfile VAT/GST.

I've also added this link to help you manage your taxes in QBO: Tax for QuickBooks Online. It covers topics such as tax filing and payment, applying sales tax to transactions, and managing VAT rates.

If you have any other concerns or questions about the VAT return, please let me know. I'll be around to help you.
