An individual who is carrying on a profession through a private
practice or carrying on a business - and is self-employed in
respect thereof - may in addition have one or more relatively small
long-term but part-time engagements in a related field. The facts
may show that it is reasonable to regard these as engagements in
the course of that private practice or business. Following the
Lorimer decision we take the view that this is a legitimate factor
to take into account. Nevertheless, it will only be one factor and
others will clearly need to be considered before a decision based
on the overall picture can be made.
This factor is likely to have more importance in the
professional field or where an individual is in business to provide
only his or her own skill.
When considering the status of a part-time engagement for an
individual who is otherwise in business providing only his or her
own skill or is a professional having a private practice - and who
regards the engagement as another engagement in the course of that
business or practice- this additional factor may be taken as a
strong pointer towards self-employment where
It should also be remembered that a person who is in business may enter into a contract which, properly considered, is an employment - see, for example, the case of Sidey v Phillips (see ESM7120). Other cases where the existence of a related business is a factor will need to be viewed on their own merits by reference to the picture overall. Where, for example, a self-employed lorry driver who supplies his or her own lorry takes on a regular part-time lorry driving engagement driving the engager's lorry then the existence of the related business is unlikely to be sufficient to make the engagement one of self-employment where other factors indicate employment. When this happens the income from that employment is taxable under Schedule E/as employment income and subject to Class 1 NICs even though the other business income is assessable under Schedule D and subject to Class 2/4 NICs.
