VAT Rollback - What happens?

[Vince_Corbin]

I have submitted my 1st VAT Return, which was automatically & successfully sent to HMRC.
I have now discovered a couple of invoices that I did not include in our return!
The sum of these significantly increase the taxable turnover.

Prior to actually making any changes I will phone HMRC to confirm exactly what they want me to do about this.
However, before doing this, I would like to be very clear in my own mind as to exactly what QuickFile does when using the Rollback functionality. The “Rollback VAT Return” button is available on the VAT Return page, so I know this functionality is available to me.

My questions are:

1. On the VAT Settings page: Should I have the “Enable Online Filing” checkbox either checked or unchecked?
2. If the “Enable Online Filing” checkbox is checked and I click on the “Rollback VAT Return” button, does anything get automatically sent to HMRC and if so what?
3. Before I click “Create New VAT Return” do I need to do anything with HMRC to ensure that our “replacement” VAT Return is accepted by them?
4. Apart from ensuring that Online Filing is enabled, are there any other issues/problems/gotcha’s that I should be aware of?

Thanks very much for any help you can provide,
Best Regards,
Vince

I would leave it as submitted, and enter the missing invoices in your quickfile accounts, which will be picked up by, and included in, your next vat return, as long as the VAT owed box 6 error, is not £10,000 or more
Otherwise its a big hassle jumping through hoops if changing the figures on a submitted vat return.

The HMRC state this:
You can adjust your next VAT Return if the net value of the errors is £10,000 or less.

PS
Quickfiles Vat rollback is not for correcting vat returns already submitted to the HMRC
