74 An entity shall offset deferred tax assets and deferred tax liabilities if, and only if: (a) the entity has a legally enforceable right to set off current tax assets against current tax liabilities; and (b) the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either: (i) the same taxable entity; or (ii) different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realise the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered. 75 To avoid the need for detailed scheduling of the timing of the reversal of each temporary difference, this Standard requires an entity to set off a deferred tax asset against a deferred tax liability of the same taxable entity if, and only if, they relate to income taxes levied by the same taxation authority and the entity has a legally enforceable right to set off current tax assets against current tax liabilities. 76 In rare circumstances, an entity may have a legally enforceable right of set-off, and an intention to settle net, for some periods but not for others. In such rare circumstances, detailed scheduling may be required to establish reliably whether the deferred tax liability of one taxable entity will result in increased tax payments in the same period in which a deferred tax asset of another taxable entity will result in decreased payments by that second taxable entity. Tax expense Tax expense (income) related to profit or loss from ordinary activities 77 The tax expense (income) related to profit or loss from ordinary activities shall be presented as part of profit or loss in the statement(s) of profit or loss and other comprehensive income. 77A [Deleted] Exchange differences on deferred foreign tax liabilities or assets 78 AASB 121 requires certain exchange differences to be recognised as income or expense but does not specify where such differences should be presented in the statement of comprehensive income. Accordingly, where exchange differences on deferred foreign tax liabilities or assets are recognised in the statement of comprehensive income, such differences may be classified as deferred tax expense (income) if that presentation is considered to be the most useful to financial statement users.
