Southern Railway of Peru Ltd v Owen

A contingent legal character does not automatically exclude a future trading liability from the computation of annual taxable profits. Ordinary commercial and accounting principles govern unless legislation requires another treatment. A provision may therefore be deducted where it is needed to match the year’s receipts with the cost of earning them and can be estimated with sufficient reliability.

A provision for deferred employee remuneration must reflect its present value. It should account for material contingencies, the expected time before payment and appropriate discounting. Accounting practice is important evidence, but neither an auditor’s opinion nor the description of an amount as a provision conclusively establishes its deductibility for income tax.

The appellant operated a railway in Peru. Peruvian legislation generally required it to pay employees a lump-sum benefit when their service ended. The benefit represented deferred remuneration for the whole period of service, although misconduct, breach of contract or failure to give proper notice could cause forfeiture.

For the accounting years 1947–50, the appellant deducted annual increases in the face value of its prospective liabilities. The Special Commissioners accepted that this accorded with correct accountancy practice, but Upjohn J and the Court of Appeal held that the deductions were impermissible.

The central issues were whether the contingent character of the liabilities legally prevented an annual provision and, if not, whether the appellant’s method produced a sufficiently reliable measure of the cost attributable to each year.

1. The appeal was dismissed by a majority of four to one. Lord Radcliffe delivered the leading speech. Earl Jowitt agreed with him, and Lord Tucker agreed with his material reasoning. Lord Oaksey also dismissed the appeal, although he regarded the liabilities as contingent until service ended. Lord MacDermott would have remitted the case to the Special Commissioners.

2. Per Lord Radcliffe, there is no absolute rule of income tax law which forbids recognition of a future receipt or liability merely because the underlying legal right or obligation is contingent at the end of the accounting year. The ascertainment of profit is primarily a question of fact governed by ordinary business practice, unless an express statutory rule excludes that practice or the facts cannot practicably be ascertained. Sun Insurance Office v Clark, (1912) AC 443, and John Cronk & Sons Ltd v Harrison, 20 TC 612, demonstrated that contingent items may be recognised at a proper valuation.

3. Where numerous similar obligations arise from trading, the practical certainty and measurable value of the aggregate may matter more than the contingency affecting each individual obligation. The relevant questions are whether omission of a figure would misstate the year’s profits and whether established accounting techniques permit a figure reliable enough for that purpose.

4. The retirement benefits were remuneration for services throughout employment. Charging the whole payment in the year when employment ended could distort annual profit. A properly measured current provision was therefore capable in principle of giving a truer account of the cost of earning the year’s receipts.

5. The deductions actually claimed were nevertheless unacceptable. They represented annual increases in the benefits’ face value and made no adequate allowance for the potentially long period before payment. Discounting was essential. The evidence also provided no satisfactory basis for evaluating deaths, early departures, legislative changes or later revisions for over-provision and under-provision. The claimed figures therefore resembled a rough reserve rather than a measured provision.

6. The Special Commissioners’ finding that the method accorded with correct accountancy practice was important but not conclusive. Per Lord Radcliffe and Lord Tucker, an auditor’s requirements under the Companies Act 1948 did not necessarily determine taxable trading profit. As the appellant had maintained its claim to the particular deductions and further evidence would effectively restart the litigation, the House declined to remit the matter.

1. House of Lords: By a majority of four to one, dismissed the company’s appeal and affirmed the result reached below. Lord MacDermott would have remitted the matter to the Special Commissioners.
2. Court of Appeal: Held that the company could not deduct the claimed provisions and affirmed Upjohn J.
3. High Court: Upjohn J held against the company’s proposed treatment of the prospective liabilities.
4. Special Commissioners: Found that making the claimed provisions accorded with correct accountancy practice, but stated the case which led to the appeals.
