My advice for anyone going through the same issue would be to send it to the 'proper' HMRC address in the Royal Mail database. After multiple attempts of 'lost' or 'undelivered' mail to the BX9 IAS postcode, I sent it to the following address instead which is listed on the Royal Mail database. Surprise, 2 days later the form was registered in my self assessment account online as having been received. Self Assessment Benton Park View Newcastle Upon Tyne NE98 1ZZ United Kingdom

I have tried to use the 'When you can expect a reply from HMRC', but none of the options are relevant to this form as it is non-standard. Could you let me know which set of options should be selected to get a vaguely accurate date estimate? The form has been added to my self assessment account online and I can see it is 'In progress', but it has been like that for over a month. Whenever I try to ring or get through to an advisor via web chat to try and expedite the process, it's impossible to speak to anyone. As some of the other users have noted, it is somewhat time-sensitive (imposed by the French authorities), so is there any way to move this along?
