Estimated future development cost is not deductible unless it has become an accrued and ascertainable liability.

Estimated future development expenditure was held not deductible in computing the year's taxable profits because the liability had not accrued in definite and ascertainable form. The court applied the Income-tax Act scheme and ruled that general commercial principles cannot justify a deduction outside statutory allowances. Even under mercantile accounting, only accrued and quantified liabilities may be debited; a contingent or floating obligation dependent on future performance, and not yet fixed in amount, is not an allowable expense. The claimed development outlay was therefore disallowed for the accounting year, and the reference was answered against the assessee.

Issues: Whether an estimated sum representing future development expenditure, not yet actually incurred and dependent on the carrying out of a promised obligation, could be deducted in computing the profits of the year.

Analysis: The receipt side of the transaction was treated as having arisen in the accounting year. The Court held that income-tax computation must follow the scheme of the Act and that no preliminary deduction on general commercial principles is permissible outside the statutory allowances. On the claimed expenditure, the Court found that the assessee's obligation to carry out development work was not a quantified or accrued liability in the accounting year, but a floating and contingent obligation dependent on future performance. Even on mercantile accounting principles, only accrued and ascertained liabilities can be debited; an estimated future outlay that may or may not arise, and whose amount is not fixed, is not a proper debit item. The Court also applied the principle that probable or inevitable future expenditure is not deductible unless the liability has already accrued in definite form during the year.

Conclusion: The estimated development expenditure was not allowable as a deduction for the year in question and the reference was answered against the assessee.

Ratio Decidendi: Under the Income-tax Act, estimated future expenditure is not deductible unless it has matured into an accrued and ascertainable liability in the accounting year; contingent or floating obligations, even under mercantile accounting, cannot be deducted in computing taxable profits.
