3.22 Income Tax Expenses
Income tax expense comprises current tax expense and deferred income tax expense. Current and deferred income tax are recognized as income or expense for the period, except to the extent that the tax arises from (a) a transaction or an event which is recognized, in the same or a different period outside profit or loss, either in other comprehensive income or directly in equity and (b) a business combination.
3.22.1 Current income tax
Current income tax is the amount of income taxes payable in respect of the taxable profit (loss) for a period. A difference between the taxable profit and accounting profit may arise when income or expense is included in accounting profit in one period, but is included in taxable profit in a different period. Differences may also arise if there is revenue that is exempt from taxation, or expense that is not deductible in determining taxable profit (loss). Current income tax liabilities (assets) for the current and prior periods are measured at the amount expected to be paid to (recovered from) the taxation authorities, using the tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.
The Group offsets current income tax assets and current income tax liabilities if, and only if, the Group (a) has a legally enforceable right to offset the recognized amounts and (b) intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.
3.22.2 Deferred income tax
Deferred income tax is recognized, using the asset-liability method, on temporary differences arising between the tax based amount of assets and liabilities and their carrying amount in the financial statements. Deferred income tax liabilities are recognized for all taxable temporary differences and deferred income tax assets are recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized. However, deferred income tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss.
Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associates, except for deferred income tax liabilities for which the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future.
The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period. The Group reduces the carrying amount of a deferred income tax asset to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred income tax asset to be utilized.
Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax liabilities and deferred income tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.
The Group offsets deferred income tax assets and deferred income tax liabilities when the Group has a legally enforceable right to offset current income tax assets against current income tax liabilities; and the deferred income tax assets and the deferred income tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity; or different taxable entities which intend either to settle current income tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred income tax liabilities or assets are expected to be settled or recovered.
3.22.3 Uncertain tax positions
Uncertain tax positions arise from tax treatments applied by the Group which may be challenged by the tax authorities due to the complexity of the transaction or different interpretation of the tax laws, a claim for rectification brought by the Group, or an appeal for a refund claimed from the tax authorities related to additional assessments. The Group recognizes its uncertain tax positions in the consolidated financial statements based on the guidance in IAS 12. The income tax asset is recognized if a tax refund is probable for taxes paid and levied by the tax authority. However, interest and penalties related to income tax are recognized in accordance with IAS 37.
