IFRS introduction

Reporting of income taxes under IFRS is subject to the accounting standard IAS 12. Access to an ‘unaccompanied’ version of IAS 12 is currently available by registering here from the IAS 12 summary page. Full access to the standards is only available by subscription to the IFRS Foundation, although this may be possible via your professional institute by subscription, which is often cheaper.

The version of IFRS used in the UK has been IFRS as endorsed by the EU. From 1 January 2021, UK-endorsed IFRS must be used. This is identical to EU-endorsed IFRS as at that date, but may change subsequently as the UK decides to possibly not endorse parts of past or future IFRS.

However, it is debatable whether other taxes which are based on a different measure fall within this definition. For example, UK petroleum revenue tax and a number of overseas taxes are calculated based on gross profit rather than profit before tax. Companies will need to assess whether
