## Facts

- Odeon Associated Theatres Ltd purchased several cinemas between 1946 and 1957, many of which required significant repairs due to damage sustained during wartime.
- Odeon estimated the expected repair costs for these cinemas and sought to deduct the estimated amounts from its taxable profits.
- The Inland Revenue challenged these deductions, maintaining that only actual expenditures, not estimated future costs, should be allowable for tax purposes.

## Issues

1. Whether estimated liabilities for future repairs can be deducted from taxable profits before the expenses are actually incurred.
2. What standard or threshold of accuracy and supporting evidence is required for such estimates to be permissible for tax deduction purposes.

## Decision

- The High Court sided with the Inland Revenue, holding that Odeon’s repair cost estimates were too uncertain and insufficiently substantiated for deduction.
- The Court of Appeal overturned the High Court, finding Odeon’s estimates to be reliable, as they were based on professional surveys and the cinemas’ actual state of repair.
- The Court distinguished this case from Southern Railway of Peru Ltd v Owen [1957] AC 334, emphasizing that reasonably accurate, evidence-backed estimates of future costs can be deductible even if some uncertainty remains.

## Legal Principles

- The matching principle in accounting requires expenses to be recorded in the same period as the revenues they relate to, supporting accurate profit calculation.
- Reasonably accurate estimates of future costs may be deductible for tax if grounded in strong supporting evidence such as expert assessments and detailed records.
- Deductibility does not extend to speculative or unclear liabilities; estimates must be realistic, supported by reliable data, and professionally reviewed.
- Each case must be assessed individually, with special consideration given to the urgency, specificity, and evidential quality of the estimated expense.

## Conclusion

The Court of Appeal’s decision in Odeon Associated Theatres Ltd v Jones established that tax deductions may be allowed for well-supported, reasonably accurate estimates of future repair costs, so long as there is clear evidence and expert analysis, reaffirming the primacy of the matching principle in tax accounting.
