Tax returns and registering for multiple types of different self-employed jobs.

A few years ago I registered as a self employed Sole Trader sand described the business as offering a wide range of services within the education / community (delivering events, parties, teaching education programmes and education consultancy). Overtime it has expanded into other areas including PA help for an elderly client which I now spend most of my time doing . I have been invoicing using my Sole Trader name which was originally set for the education and community service and have been putting my income into this bank because I see the PA work as a service. I have also been submitting my tax returns all as one and have been keeping all book records as one. Is this allowable under HMRC rules? Please advise if I need to make any changes.  

Hi Jay Norton,

They should really be split to show multiple source on your retrun and different sets of accounts for each one. 

Thank you.
