Guest lecture by Mr Jörg Semmner (tax advisor/chartered accountant/tax partner) from EY Tax GmbH

Insights into ‘Income Taxes and Deferred Taxes – Tax Accounting in Theory and Practice’: Many thanks to Mr Jörg Semmner (tax advisor/auditor/tax partner) from EY Tax GmbH for his extremely practical guest lecture at WFI in January 2026.

The presentation addressed key issues relating to income tax accounting under IFRS. The focus was on the recognition and measurement of deferred taxes, the distinction between temporary and permanent differences, and their impact on tax expense and effective tax rate. Another key topic was the impairment testing of deferred tax assets, which in practice often involves considerable discretion and forecasting uncertainties. Furthermore, the meeting covered exceptions to the accounting of deferred taxes, the tax reconciliation statement in the notes, and current issues relating to tax rate changes.

We would like to thank EY Tax GmbH for the highly practical and informative presentation.
