Annex 1: Minor Changes in the Law Change 2: Trading income: omission of references to a company carrying on a profession or a vocation: section 35 (and other sections) Corporate bodies and vocations The nature of a vocation
“Vocation” is not defined for tax purposes.
According to the Oxford English Dictionary a vocation is:
	the fact or feeling of being called to undertake some specific career, function or occupation;
	a strong feeling of fitness or suitability for a particular career;
	a mode of life or employment regarded as requiring dedication.
The thread that ties all of these definitions together is that the exercise of a vocation requires a personal commitment to a particular activity.
Corporate bodies are artificial persons. They are not animated by callings. They do not have careers, still less can they be said to have feelings of fitness and suitability as regards a particular set of activities. Nor do they have a mode or a way of life and they do not engage in activities out of a sense of dedication.
That being the case it does not appear possible for a corporate body to carry on a vocation.
