Imagine you previously claimed a deduction for an expense under Income from Other Sources — say, interest on a loan taken to earn dividend income — and the lender later waives that loan or you get a refund of that expense. Should you get to keep that tax benefit for free? Section 59 says: absolutely not.
Section 59 is the 'give-back' rule for Income from Other Sources. It imports the logic of Section 41(1) — which normally applies to business income — and makes it equally applicable when you're computing income under Section 56 (i.e., Income from Other Sources). In simple terms: if a deduction was allowed to you in an earlier year while computing your 'other source' income, and in a later year that very expense is recovered, refunded, or the liability behind it ceases to exist, then the recovered amount becomes taxable in the year of recovery, under the same head — Income from Other Sources.
Why does this matter for the exam? Because it closes a loophole. Without Section 59, a taxpayer could claim a deduction in Year 1, and when the expense bounces back in Year 2, claim it is not taxable (since it's not a business receipt). Section 59 shuts that door. The trigger is Section 41(1): that provision says any recovery of a previously deducted loss, expenditure, or ceased liability is brought back to tax. Section 59 simply says — apply that same rule to Section 56 income too. The key condition is that the deduction must have been actually allowed in a prior assessment. If no deduction was ever claimed or allowed, Section 59 has no bite. This section is tested as a short theory or application question (2–4 marks) — typically asking whether a recovered amount is taxable or not in a given scenario.
