I've dealt with a number of tax enquiries over the years with varying degrees of detail required. For the latest, relating to a builder/contractor earning around 40k pa HMRC met me and the client a couple of weeks back. As it happens records in this case aren't too bad but the follow up letter includes a five page schedule of required information relating to private and personal income and expenditure. The detail requested (for 2014/15) I would struggle to fill in for my personal affairs - take away meals, cinema tickets, hairdressing, christmas expenditure, cleaning products etc etc for two or three years ago. The income section also asks for spouse earnings - I know these as she is self employed and I act but my client under enquiry does not know. Obviously I do not want to be obstructive with HMRC but I would be astonished if my client could answer many of the questions with any degree of accuracy. Has any one any practical tips on dealing with this sort of thing in way that is satsifactory to HMRC?
