Mumbai ITAT Permits Tax Deduction for ₹16.26 Crore Derivative Mark-to-Market Losses

The Income Tax Appellate Tribunal in Mumbai allowed a deduction amounting to ₹16.26 crore for mark-to-market losses incurred on derivative financial instruments. The tribunal reviewed the commercial nature of the derivative transactions and determined that the resulting valuation losses represent allowable business expenditures rather than contingent liabilities. This decision addresses a recurring area of tax litigation concerning the deductibility of unrealized market losses on hedging portfolios.

Mark-to-market accounting requires businesses to adjust the carrying value of financial instruments to reflect current market prices at the end of a reporting period. Tax authorities have traditionally contested the tax deductibility of such losses on the grounds that they are notional or contingent until the underlying contracts are actually settled. However, judicial consensus increasingly recognizes that losses on regular trading or hedging derivatives reflect genuine economic erosion that impacts corporate income.

Finance managers and corporate tax consultants should review their treatment of derivative losses and verify if pending assessments involve similar notional write-downs. Taxpayers must ensure proper documentation links derivative portfolios to underlying commercial hedging activities to secure similar treatment. Bottom line: corporate taxpayers facing tax disallowances on derivative valuation losses can utilize this ruling to claim legitimate deductions.
