Trading liability cessation under tax law depends on substance and facts, not merely unpaid entries or limitation principles.

Section 41(1) of the Income-tax Act applies only where an earlier allowance or deduction in respect of a trading liability is followed by a benefit through remission or cessation of that liability. In the context of unclaimed bonus written back in the accounts, the existence of an unpaid entry or a possible industrial dispute is not conclusive. The liability must be examined in substance, having regard to both the income-tax provisions and the Payment of Bonus Act, including the factual position after prolonged non-claim and write-back. The tribunal's approach was criticised as incomplete because it did not fully test whether the bonus had in effect ceased to remain a real liability.

Issues: Whether unclaimed bonus written back in the accounts could be assessed under section 41(1) of the Income-tax Act, 1961, and whether such unpaid bonus represented a remission or cessation of trading liability.

Analysis: Section 41(1) applies only where an allowance or deduction has earlier been allowed in respect of a trading liability and the assessee later obtains a benefit by way of remission or cessation of that liability. The statutory scheme of the Payment of Bonus Act, 1965 was examined, including the time-limit for payment of bonus and the machinery for recovery. The earlier authorities on limitation and cessation of liability were considered, but the Court stressed that the question whether a liability has ceased must be decided in the light of the income-tax provisions as well as the statute governing the liability. On the facts, the Tribunal had proceeded on an incomplete view by treating the existence of a possible industrial dispute as conclusive, without investigating whether the unclaimed bonus had in substance ceased to remain a real liability after several years of non-claim and write-back.

Conclusion: The Tribunal's conclusion that section 41(1) was inapplicable was not accepted as final on the existing record, and the matter required fresh consideration on the relevant facts.

Final Conclusion: The reference was not answered on the merits, and the matter was sent back for disposal in accordance with the legal principles stated.

Ratio Decidendi: For section 41(1), cessation of a trading liability depends on the substance of the liability in the statutory context and relevant facts, and cannot be determined mechanically by the mere continued existence of an unpaid entry or by limitation principles alone.
