This online session targets Luxembourg-based taxpayers, corporate finance teams, and tax advisors seeking clarity on the upcoming 2026 tax filing obligations. The webinar arrives amid ongoing adjustments to Luxembourg’s tax framework, including recent updates to personal income tax brackets, corporate tax rates, and the implementation of OECD Pillar Two minimum taxation rules for large multinational groups.

- Impact of Pillar Two and International Reforms: For multinational enterprises with annual revenues exceeding €750 million, the session will cover the transitional safe harbors and qualifying domestic minimum top-up tax (QDMTT) mechanics applicable for fiscal year 2026. Attendees will gain insights into data gathering obligations and the interplay with existing Luxembourg tax incentives.
- Risk Mitigation and Penalty Avoidance: Experts will highlight frequent mistakes such as incorrect classification of investment income, overlooked foreign tax credits, and improper handling of stock option exercises. The session includes a live Q&A to address entity-specific scenarios, enabling participants to proactively adjust their compliance workflows before the filing window opens.
