Income tax expense represents the sum of the tax currently payable and deferred tax.
The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the statement of comprehensive income because of items of income or expense that are taxable or deductable. The company's liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the end of the reporting period.
Deferred tax is recognised on timing differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit. Deferred tax liabilities are generally recognised for all taxable timing differences. Deferred tax assets are generally recognised for all deductable temporary differences to the exent that it is probable that taxable profits will be available against which those deductable timing differences can be utilised. The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that is is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the aseet realised, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. Deferred tax liabilities are presented within provisions for liabilities and deferred tax assets within debtors. The measurement of deferred tax liabilities and assets reflect the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.
Current and deferred tax for the year is recognised in profit and loss, except when they related to items that are recognised in other comprehensive income or directly in equity, in which case, the current and deferred tax is also recognised in other comprehensive income or directly in equity respectively.
