"34 Expenses not wholly and exclusively for trade and unconnected 5 losses (1) In calculating the profits of a trade, no deduction is allowed for – (a) expenses not incurred wholly and exclusively for the purposes of the trade, or (b) losses not connected with or arising out of the trade. 10 (2) If an expense is incurred for more than one purpose, this section does not prohibit a deduction for any identifiable part or identifiable proportion of the expense which is incurred wholly and exclusively for the purposes of the trade."
"[t]o ascertain whether the money was expended to serve the purposes of the taxpayer's business it is necessary to discover the taxpayer's 'object' in making the expenditure: see Morgan v Tate & Lyle Ltd[1955] AC 21 at 37 and 47. As the taxpayer's 30 'object' in making the expenditure has to be found, it inevitably follows that (save in obvious cases which speak for themselves) the commissioners need to look into the taxpayer's mind at the moment when the expenditure is made. After events are irrelevant to the application of s 130 except as a reflection of 35 the taxpayer's state of mind at the time of the expenditure. If it appears that the object of the taxpayer at the time of the expenditure was to serve two purposes, the purposes of his business and other purposes, it is immaterial to the application of s 130(a) that the business purposes are the predominant 40 purposes intended to be served. The object of the taxpayer in making the expenditure must be distinguished from the effect of the expenditure. An expenditure may be made exclusively to serve the purposes of 14 the business, but it may have a private advantage. The existence of that private advantage does not necessarily preclude the exclusivity of the business purposes. For example a medical consultant has a friend in the South of France who is also his patient. He flies to the South of 5 France for a week, staying in the home of his friend and attending professionally on him. He seeks to recover the cost of his air fare. The question of fact will be whether the journey was undertaken solely to serve the purposes of the medical practice. This will 10 be judged in the light of the taxpayer's object in making the journey. The question will be answered by considering whether the stay in the South of France was a reason, however subordinate, for undertaking the journey, or was not a reason but only the effect. If a week's stay on the Riviera was not an 15 object of the consultant, if the consultant's only object was to attend on his patient, his stay on the Riviera was an unavoidable effect of the expenditure on the journey and the expenditure lies outside the prohibition in s 130."
“In the majority of cases a self-employed person has what can properly be described as his place of business or base of operations. 20 In the case of the medical practitioner, it is his surgery or consulting rooms; in the case of the shopkeeper it is his shop; in the case of the barrister it is his chambers, and so on.”
"the locus in quo of the trade, from which it radiated as a centre. He went from it to the surrounding sites according as 30 his work demanded."
"the base from which [he] carried on his business"
"no place which you could call his place of business except his 35 home". 18 In other words, all three of the Lords Justices held that Mr Horton's home was the only place of business he had. That was why his travel to and from his home was deductible; as Salmon LJ put it: "
"In my view, where a person has no fixed place or places at which he carries on his trade or profession but moves continually from one place to another, at each of which he consecutively exercises his trade or profession on a purely 35 temporary basis and then departs, his trade or profession being in that sense of an itinerant nature, the travelling expenses of that person between his home and the places where from time to time he happens to be exercising his trade or profession will normally be, and are in the case before me, wholly and 40 exclusively laid out or expended for the purposes of that trade or profession."
“Mr Newsom, in a letter to the Inspector of Taxes…..conceded that ‘a man’s profession is not exercised until he arrives at the 15 place at which it is carried on’. In my judgment this proposition is, in general, true.”
