Taxation represents the sum of the tax currently payable and deferred tax.
The company's liability to tax is calculated using the tax rates that have been enacted or substantively enacted by the end of the reporting period.
Deferred tax is recognised on all timing differences between the carrying amounts of the assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit.
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period to which the liability is settled or the asset realised, based on tax rates and laws that have been enacted or substantively enacted by the end of the reporting period.
