Assessment-year law and reserve-entry timing control tax liability, dead rent deduction, and development rebate eligibility.

Assessment-year law governed liability to tax on income earned before 1 April 1960, so the removal of the earlier exemption applied to that year and the assessee was taxed on that income. Dead rent under the lease was treated as minimum royalty and therefore as revenue expenditure deductible in computing business profits. Development rebate was allowed because the statute required debit to profit and loss and credit to reserve, but fixed no express time limit for those entries; the reserve could be created before assessment was completed, and the rebate remained available if the conditions were satisfied by then. The reference thus produced a mixed result, with one issue decided for Revenue and the others for the assessee.

Issues: (i) Whether the assessee was liable to tax on income earned prior to 1 April 1960; (ii) Whether dead rent of Rs. 5,343 was allowable as a deduction; (iii) Whether development rebate of Rs. 13,239 was allowable despite the timing of the reserve entry.

Issue (i): Whether the assessee was liable to tax on income earned prior to 1 April 1960.

Analysis: The applicable law for assessment was the law in force in the assessment year, and Parliament was competent to enact retrospective or prospective provisions. The amendment removing the earlier exemption applied to the assessment year in question, so prior accrual of income did not preserve immunity from taxation.

Conclusion: The issue was decided against the assessee and in favour of Revenue.

Issue (ii): Whether dead rent of Rs. 5,343 was allowable as a deduction.

Analysis: Dead rent was treated as a form of minimum royalty under the lease. Such payment was regarded as revenue expenditure deductible in computing business profits.

Conclusion: The issue was decided in favour of the assessee.

Issue (iii): Whether development rebate of Rs. 13,239 was allowable despite the timing of the reserve entry.

Analysis: The statutory condition required debit to the profit and loss account and credit to a reserve account, but no time limit was expressed for making those entries. The entries could be made before assessment was completed, and the assessing authority could allow the rebate if the statutory requirements were satisfied by that stage.

Conclusion: The issue was decided in favour of the assessee.

Final Conclusion: The reference was answered with one issue against the assessee and the remaining issues in its favour, resulting in a mixed outcome on the tax questions referred.

Ratio Decidendi: Where a taxing provision requires creation of a reserve as a condition for development rebate, the requisite entries may be made before completion of assessment unless the statute expressly fixes an earlier deadline; the applicable assessment-year law governs liability to tax.
