“Before turning to those cases I should, I think, say something about the way in which partnership profits are assessed to tax. There are, in effect, three stages. First, the profits of the firm for an appropriate basis period must be ascertained. What has to be ascertained is the profits of the firm and not of the individual partners. That is not, I think, stated anywhere in the Income Tax Acts, but it follows necessarily from the fact that there is only one business and not a number of different businesses carried on by each of the partners.”
“It is well known that the UK tax legislation has never made positive provision about what expenses or deductions are deductible in the computation of profits of a taxable business. The relevant test has always been framed in purely negative terms”
“ Was the payment made wholly and exclusively for the purposes of the taxpayers trade? Whether a payment is made exclusively for the purpose of the taxpayer's trade or partly for that purpose and partly for another is a question of fact for the Commissioners. The Court can interfere only if the Commissioners have made an error of law in reaching their conclusion. The principles on which the Court acts are to be found in the speech of Lord Radcliffe in Edwards v Bairstow & Another 36 TC 207 ;[1956] AC 14 and are too well known to repeat. It is sufficient to say that the Court will interfere where the true and only reasonable conclusion from the facts found by the Commissioners contradicts the determination. In the case of an individual taxpayer, the other purpose is usually a private purpose of his own. In a case like the present, where the taxpayer is a company forming part of a group, the other purpose is likely to be the purpose of the trade of one or more of the other companies in the group. But the same principles apply ... The leading modern cases on the application of the “exclusively” test are Mallalieu v Drummond 57 TC 330 ;[1983] 2 AC 861 and MacKinlay v Arthur Young McClelland Moores & Co 62 TC 704 ;[1990] 2 AC 239 . From these cases the following propositions may be derived: 1. The words “for the purposes of the trade” mean “to serve the purposes of the trade”
“The well known case of Morgan (Inspector of Taxes) v Tate & Lyle Ltd[1955] AC 21 , 35 TC 367 is authority for the proposition that money spent for the purpose of preserving the trade from destruction can properly be treated as wholly and exclusively expended for the purposes of the trade.”
“Where expenditure is made, not only once and for all, but with a view to bringing into existence an asset or advantage for the enduring benefit of a trade, I think there is very good reason (in the absence of special circumstances leading to the opposite conclusion) for treating such expenditure as property attributable not to revenue but to capital.”
“… as to whether this is a payment properly attributable to capital or to revenue, in my opinion the principle which is to be deduced from the cases is that where a sum of money is laid out for the acquisition or improvement of a fixed capital asset it is attributable to capital, but that if no alteration is made in the fixed capital asset by the payment, then it is properly attributable to revenue, being in substance a matter of maintenance, the maintenance of the capital structure or the capital assets of the Company.”
“It appears to me that the legal expenses which were incurred by the Respondent Company did not create any new asset at all but were expenses which were incurred in the ordinary course of maintaining the assets of the Company, and the fact that it was maintaining the title and not the value of the Company’s business does not, in my opinion, make it any different.”
