Current tax is the amount of income tax payable in respect of taxable profit for the year or prior years. Tax is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the year end. Current taxation assets and liabilities are not discounted.
Deferred tax assets are recognised in respect of all timing differences at the reporting date. Unrelieved tax losses and other deferred tax assets are only recognised 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 assets and liabilities are measured using the tax rates and laws that have been enacted or substantively enacted by the reporting date and that are expected to apply in the periods in which any timing differences are expected to reverse. Deferred tax assets and liabilities are not discounted. No deferred tax asset has been recognised for the current year.
