BIM35030 - Capital/revenue divide: introduction: is the distinction relevant today?

Where accountancy can give the wrong result for tax purposes

Capital expenditure is not allowable as a deduction, nor is it income taxable as trade profits.

Income tax law and accountancy are not fully aligned on the treatment of capital expenditure. Income tax law takes precedence. You therefore need to pay particular attention to those areas where income tax and accountancy differ in their treatment of capital expenditure. For a description of the interaction between accountancy and income tax see BIM31000 onwards.

You are required to establish the correct measure of profits for income tax purposes. The profits shown in a set of accounts drawn up in accordance with UK GAAP will only coincidentally yield the required figure. A major area of difference is in the treatment of capital expenditure. Except in those cases where capital expenditure is specifically allowed by statute (for example ICTA88/S77 allows certain costs of raising loan finance - see BIM45800 onwards) capital expenditure is not allowable in computing profits for income tax purposes. A common example of the difference is provided by depreciation. The depreciation of a fixed capital asset constitutes a proper deduction in computing profits under UK GAAP but for income tax purposes the expense is not allowed on the basis that it is capital.

In the CT field, however, there is a growing body of statute law that recognises accounting entries for tax in computations of income, notwithstanding the fact that they may be of a capital nature as a matter of tax principle. In particular, from 1 April 2002 the depreciation of goodwill and other fixed intangible assets (including intellectual property) becomes allowable for CT in certain circumstances as a result of the legislation in FA02/SCH29, (see BIM35500 onwards).

Lloyd J in the recent Herbert Smith judgement (see BIM35210) identified the following circumstances where, apart from the treatment of capital expenditure, accountancy can yield the wrong result for tax purposes:


  • Where the accounts are based on an analysis of the facts that is wrong in law (for example, CIR v Gardner Mountain & D’ Abrumenil Ltd [1947] 29TC69).
  • Where accounts prepared in accordance with GAAP are found to be based on factual assumptions which are insufficiently reliable (for example, Owen v Southern Railway of Peru Ltd [1956] 36TC602).
  • Where accounts prepared in accordance with GAAP are simply inconsistent with the true facts (for example, BSC Footwear Ltd v Ridgway [1971] 47TC495).
