Challapalli Sugars Ltd v CIT

I borrowed to buy and install my plant and paid interest before production started — can I add that interest to the cost of the plant and claim depreciation on it?

The Income-tax Act, 1961 was repealed on 1 April 2026. It still governs income earned up to 31 March 2026, and every proceeding about those years however late — assessment, reassessment, rectification, penalty, revision and appeal alike. Income earned from 1 April 2026 is governed by the Income-tax Act, 2025. What changed, and which Act governs your year →

I borrowed to buy and install my plant and paid interest before production started — can I add that interest to the cost of the plant and claim depreciation on it?

Yes. The Supreme Court held that interest paid on money borrowed to acquire and install plant and machinery, for the period before production commences, forms part of the actual cost of the asset. 'Actual cost' is not defined in the Act, so it must be read in the sense no commercial man would misunderstand — that is, by the accepted accountancy rule, which brings in all expenditure necessary to bring the asset into existence and put it in working condition. Depreciation and development rebate are therefore admissible on the capitalised interest.

Decided by the Supreme Court (Supreme Court of India — Hans Raj Khanna and A.C. Gupta JJ (judgment by Khanna J)) on 1974-10-31, reported as 1975 AIR 97; 1975 SCR (2) 538; (1975) 3 SCC 572; 98 ITR 167; 1975 SCC (Tax) 65; 1975 Tax LR 40. It bears on section 43(1), section 32, section 36(1)(iii) of the Income Tax Act 1961, in Deductions & Disallowances matters.

Superseded by amendment. The principle stands and the case remains constantly cited (the source page records over 400 citing decisions), but the field is now occupied by statute: the proviso to section 36(1)(iii) and Explanation 8 to section 43(1) of the 1961 Act govern pre-operative and post-acquisition interest directly. The judgment itself was decided on the 1922 Act. No later decision doubting the reasoning was checked.

Why it matters

This is the foundation of pre-operative interest capitalisation in Indian tax law, and it is the reason the Act now carries a proviso to section 36(1)(iii) and Explanation 8 to section 43(1). The Court's method matters as much as its result: where the Act leaves a commercial expression undefined, ordinary accountancy usage supplies the meaning. It is still the authority cited whenever the boundary between capitalising and expensing borrowing cost is argued, and it is the counterpart to India Cements — interest after production commences is revenue under section 36(1)(iii); interest before it belongs in the cost of the asset. The judgment also decides a wealth-tax deduction point under section 5 of the Income-tax (Amendment) Act 1972.
