Help please. I rent a little flat out and need to fill in my self-assessment form, as every year. I can't find my UTR number anywhere - I realise it is a 10-digit number that is usually seen in the top left corner of HRMC correspondence, but unfortunately I cannot find any records (long story). I used to have a card with my UTR in it but I lost my purse a while ago and the card with it. The last correspondence I got from the tax office does not show my UTR.
I have tried phoning their online helpdesk but I just cannot get through. What can I do? I am also having problems logging in - what a nightmare. Thanks.
