In such a circumstance, an entity shall recognise and measure its current or deferred tax asset or liability applying the requirements in FRS 12 based on taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates determined applying this Interpretation.
This Interpretation shall be applied for annual reporting periods beginning on or after 1 January 2019. Earlier application is permitted. If an entity applies this Interpretation for an earlier period, it shall disclose that fact.
