Current tax represents the amount of tax payable or receivable in respect of the taxable profit (or loss) for the current or past reporting periods. It is measured at the amount expected to be paid or recovered using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.
Deferred tax represents the future tax consequences of transactions and events recognised in the financial statements of current and previous periods. It is recognised in respect of all timing differences, with certain exceptions. Timing differences are differences between taxable profits and total comprehensive income as stated in the financial statements that arise from the inclusion of income and expense in tax assessments in periods different from those in which they are recognised in the financial statements. Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.
Deferred tax is measured using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date that are expected to apply to the reversal of timing differences.
