Compensatory interest and crystallised liability determine deductibility of delayed tax and royalty payments under section 37(1).

For deduction under section 37(1), the substance of an impost prevails over contractual labels: interest automatically charged for delayed sales tax payment is compensatory, not penal, and is deductible as business expenditure. A liability for royalty-related interest becomes deductible when it is finally determined and crystallised in the relevant accounting year, even if the dispute arose earlier. Interest on interest for belated royalty payment was treated as compound interest arising from delay, not a penal levy, and was allowable when the liability crystallised under the mercantile system. The governing test is whether the outgoing is compensatory in substance and whether the liability has crystallised in the relevant year.

Issues: (i) Whether interest paid on belated payment of sales tax, described in the lease deed as penalty, was compensatory and deductible under section 37(1) of the Income-tax Act, 1961; (ii) Whether the liability to pay interest on royalty to the Raja of Kutlehar crystallised in the relevant year; (iii) Whether interest on interest for belated payment of royalty was a deductible revenue expenditure and crystallised in the relevant year.

Issue (i): Whether interest paid on belated payment of sales tax, described in the lease deed as penalty, was compensatory and deductible under section 37(1) of the Income-tax Act, 1961.

Analysis: Deductibility under section 37(1) depends on whether the impost is laid out wholly and exclusively for business and is not of a penal character. The character of the impost is determined by its substance and the statutory scheme, not merely by the nomenclature used in the contract. Where interest is automatically attracted for delayed payment, it is compensatory in nature. The lease deed had to be read with section 17A(1) of the H. P. General Sales Tax Act, 1968, under which delayed tax payment carried simple interest. The amount claimed matched the statutory interest liability.

Conclusion: The interest on delayed payment of sales tax was compensatory and allowable as a deduction; the issue was decided in favour of the assessee.

Issue (ii): Whether the liability to pay interest on royalty to the Raja of Kutlehar crystallised in the relevant year.

Analysis: A liability becomes deductible when it is finally determined and crystallised, even if the dispute originated earlier. The dispute over the royalty-related liability was finally settled by the judicial order dated 10 January 1996, and that settlement fixed the amount payable in the relevant accounting year. The question was therefore treated as one of crystallisation of liability rather than a substantial question of law warranting a different conclusion.

Conclusion: The liability crystallised in the relevant year and the deduction was allowable; the issue was decided in favour of the assessee.

Issue (iii): Whether interest on interest for belated payment of royalty was a deductible revenue expenditure and crystallised in the relevant year.

Analysis: Interest on interest was treated as compound interest arising from delayed payment of royalty rather than as a penal impost. On the facts, the liability related to an earlier period but was finally quantified and settled only when the dispute ended and the amount was paid during the relevant assessment year. Since the assessee followed the mercantile system, the deduction was allowable in the year in which the liability crystallised.

Conclusion: The interest on interest was deductible and the liability crystallised in the relevant year; the issue was decided in favour of the assessee.

Final Conclusion: The appeals failed because the disputed amounts were held to be compensatory or otherwise deductible business expenditure, and the liability in question was found to have crystallised in the relevant year.

Ratio Decidendi: For section 37(1) deductions, the decisive test is whether a statutory impost is compensatory or penal in substance, and a liability becomes deductible when it crystallises in the relevant accounting year.
