“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. 35 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. The income 40 of the firm for the year is then treated as divided between the partners who were partners during the year to which the claim relates—the year of assessment—in one of the many senses of that word … That is the second stage. The tax payable is then calculated according to the circumstances of each partner … When the tax exigible in respect of each share of the partnership income has 45 been ascertained the total tax payable is calculated. Section 152 (formerly Rule 9 10 of the Rules applicable to Cases I and II of Sch D) provides that the total sum so calculated is to be treated as “one sum … separate and distinct from any other tax chargeable on those persons … and a joint assessment shall be made in the partnership name.”
“Now there is, if I may say so respectfully, a confusion here. It is perfectly true that in Heastie v Veitch & Co.,[1934] 1 KB 535 , 547 Romer L.J. remarked that by rule 10 applicable to Cases I and II (now contained in s. 152 of the Act) a 20 partnership is treated for the purposes of Sch D taxation as a separate entity from the individual partners composing the firm—that is at stage three of Vinelott J’s analysis—but there is nothing in that decision nor in the other cases cited by Slade L.J. to justify a conclusion that it can permissibly be so treated at stage one of the analysis in relation to sums which have been received by a 25 partner from the partnership funds in his capacity as a partner.”
“15. However, as Mr Vaines correctly pointed out, Vinelott J, and indeed the 30 House of Lords in that case, was concerned with the position as it existed before the introduction of self-assessment when a partnership was treated for income tax purposes, undersection 111 of the Income and Corporation Taxes Act 1988 , as “an entity which is separate and distinct from those persons” who carried out the trade or profession in partnership and it would appear that this was why 35 Vinelott J referred to there being “only one business”
