I have submitted many VAT returns to HMRC using Quickfile, with the system extracting the data from the invoices in the Quickfile system.
For some reason this has simply stopped happening. In the “prepare VAT return” screen there are no data - no numbers - in the draft VAT return. There are 4 invoices in the period [May Jun Jul 2023] all of which are present in the period on the Quickfile system without error.
I have disconnected and reconnected Quickfile authority at the HMRC site, as one page recommended. No difference. Just a mystery why the VAT return is not pulling the information from the invoices as it normally does.
