Income taxes include all domestic and foreign taxes that are based on taxable profits.
Current tax for current and prior periods is, to the extent that it is unpaid, recognised as a liability. Overpayment of current tax is recognised as an asset. Current 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.
