Incomes Exempt from Tax (s.10, 10AA); Casual Income — Law of Taxation Notes

Incomes Exempt from Tax (s.10, 10AA); Casual Income

Two people receive money in the same year — one gets ₹5 lakh as agricultural income, the other ₹5 lakh as a gratuity on retirement. Neither pays tax on it. Section 10 is the long list of such receipts the Act decides, for policy reasons, to leave wholly out of total income — and knowing a dozen of them by section number is guaranteed marks.

Exempt incomes under s.10

Section 10 lists incomes that do not form part of total income at all — they are excluded before you even begin computing. The rationale varies (encouraging agriculture, protecting the retired, honouring diplomats, promoting exports), but the effect is the same: exempt. Key items to memorise with their anchors:

s.10(1) — agricultural income (Topic 4).
s.10(2) — a member’s share in the income of a HUF.
s.10(2A) — a partner’s share of firm profits (the firm is separately taxed).
s.10(10) — gratuity (within limits).
s.10(10A) — commuted pension.
s.10(10AA) — leave encashment on retirement (within limits).
s.10(10D) — sums received under a life insurance policy (subject to conditions).
s.10(11)/(12) — provident fund accumulations.
s.10(13A) — house rent allowance (HRA), to the prescribed extent.
s.10(14) — special allowances to meet duties (subject to limits).
s.10(16) — scholarships granted to meet the cost of education.
s.10(17) — allowances of MPs/MLAs.
s.10(23C) — income of certain educational/medical institutions and funds.
s.10(26) — income of members of Scheduled Tribes in specified areas.
s.10(34)/(35) — (historically) dividend/mutual-fund income exemptions.
s.10(38) — (historically) long-term capital gains on listed shares (now modified by s.112A).

Section 10AA — SEZ units. A deduction (in the nature of an exemption) for profits of units in a Special Economic Zone, for a number of years on a tapering scale, to promote exports (see Unit V for the SEZ concept).

Casual income. A casual and non-recurring receipt — winnings from lotteries, crossword puzzles, races (including horse races), card games, gambling or betting — is income (expressly, under s.2(24)(ix)) and is taxable at a flat special rate under s.115BB (no basic exemption, no deductions against it, and TDS applies). So “casual income” is not exempt; only genuinely windfall gifts/receipts of a personal nature that are not income at all fall outside — but statutory winnings are squarely taxed.

Section 10 (opening): “In computing the total income of a previous year of any person, any income falling within any of the following clauses shall not be included— …”

🧩 WORKED EXAMPLE — Quiz-show prize

Facts. A TV channel pays ₹20 lakh to the winner of a quiz/reality programme.

Rule. Winnings from games/quizzes are “casual income” under s.2(24)(ix), taxable under “Income from Other Sources” at the flat rate in s.115BB, with TDS deducted at source under s.194B before payment; no basic exemption or expense deduction is allowed against it.

Apply. The ₹20 lakh is a casual, non-recurring winning; the channel must deduct TDS before paying, and the winner is taxed at the special flat rate.

Conclusion. The prize is fully taxable (not exempt), at the special rate, with TDS — a favourite exam trap because students assume “casual” means “tax-free”.

In Simple Terms: Section 10 is the list of receipts the law keeps out of your income entirely — agricultural income, gratuity, HRA, scholarships, and more. But do not confuse “casual income” (lottery/quiz winnings) — that is taxable at a flat rate with TDS, not exempt.

Case Laws

CIT v G.R. Karthikeyan (1993) — winnings from a car rally are “income” of a casual nature and taxable; the s.2(24) list is illustrative, not restrictive.
