Mahaveer Kumar Jain v. Commissioner of Income Tax
Background
The appellant, a Jaipur resident, won Rs. 20 lakhs in a Sikkim State Lottery bumper draw in 1986 and had already paid income tax on it at source under the Sikkim State Income Tax Rules. The Income Tax Department sought to also tax this lottery income under the Indian Income Tax Act, 1961, and a dispute also arose over whether a deduction claimed under Section 80TT should be computed on the gross or net lottery amount. The Rajasthan High Court had ruled against the appellant-assessee and in favour of the Revenue.
Decision Breakdown
The Supreme Court held that under Article 371F(k) of the Constitution, a special constitutional provision for Sikkim, only Sikkim's own income tax regulations applied to this lottery income for the relevant period, and there was no express statutory provision permitting the same income to be taxed again under the Indian Income Tax Act. Relying on the general principle that double taxation is not permitted unless the legislature expressly authorizes it, and that any doubt in a taxing statute should be resolved in favour of the taxpayer, the Court held the lottery income could not be taxed a second time under the IT Act. Having decided the income was not taxable at all under the IT Act, the Court held the separate dispute over gross-vs-net computation under Section 80TT had become academic. The appeal was allowed.
Lesson Learnt
A taxpayer cannot be taxed twice on the same income unless a law expressly says so, and ambiguity in tax statutes is resolved in the taxpayer's favour: a principle of particular relevance where special constitutional arrangements (like Sikkim's) carve out a separate tax regime.
