I recently registered for MTD Vat returns and have registered with Datadear to submit electronically. I recently submitted outstanding returns. I was making repayment returns and had 3 sets of returns to make. When I submitted the first return it defaulted to a Nov return but was supposed to be the return for Aug. I didnt realise and proceeded to submit.
I contacted HMRC and was told that I would need to correct and submit a return for Aug in order for they to process subsequent returns.
However, each time I attempt to submit a return, the date autofills to date of next return in feb, and will not allow me to submit a previous return.
HMRC say I need to get the software supplier to unlock this for me??
