I just want some help with a theoretical scenario about VAT returns and QuickFile. If I completed a VAT return on quickfile and had submitted it to HMRC, but a week or so later realized that I had not accounted for an invoice that would have affected the amount paid in the last VAT period. If I then input this invoice, what happens to my VAT, will it just automatically be adjusted for my next VAT return for the next VAT period.
So to be clear, I complete a VAT return for JANUARY to MARCH, and then in April I input an invoice dated for March that should have already been input before the VAT return was submitted, what will happen when I come to submit my APRIL to JUNE VAT return, because when I tell it the period to look at in QuickFile to take the data from for the next return I would be entering April to June, so the invoice that I entered late for March would not be included would it?
What is the correct way to handle this scenario?
