Section 41(1) applies only where expenditure or a trading liability was previously allowed as a deduction and the taxpayer subsequently obtains a benefit through remission or cessation. Unpaid interest earlier disallowed under section 43B did not satisfy that condition. Continued balance-sheet recognition, with no write-back, waiver, settlement or discharge, also did not establish cessation; a lender's discounted assignment to an asset reconstruction company did not extinguish the debt. The addition was deleted. Depreciation remained available for a mortgaged building in an existing asset block because mortgage does not transfer ownership and no sale, discard, business unavailability or permanent closure was shown; depreciation was allowed.
