There are many pitfalls in the Luxembourg tax procedures that can be easily overlooked. This may quickly result in tax penalties and disputes for companies and liability issues for the people in charge.

A profound knowledge of the tax procedures is therefore key to prevent disputes from arising in the first place. But not each and every tax dispute can be avoided. There has been a steady increase in tax disputes in the last few years and this trend will continue. But tax disputes are often lost, not on the merits of a case, but by ignoring the formal steps of proceedings and by executing an improper litigation strategy.

Tax professionals need to gain a better understanding of the tax procedural law. This will empower them to better prevent, manage and solve tax disputes. This course will give a holistic overview of the Luxembourg tax procedures, controversy and litigation for direct taxes (income, business and wealth tax), for VAT and other taxes.

By the end of this training, participants will:

  • have a greater understanding of the rights and obligations of taxpayers in Luxembourg;
  • acquire tax knowledge that helps you to prevent and manage disputes;
  • become aware of the tax penalty and tax liability regime;
  • be able to identify the risk of tax evasion and fraud in your organisation and during the anti-money laundering review process for new clients;
  • have a bigger picture of the information and formal powers of the tax administration.


  • Tax penalties for non-compliance in case of tax and VAT returns not or lately filed, incomplete or incorrect (incl. calculation of deadlines)
  • Tax enforcement in case of non-payment (incl. statute of limitations and liability for unpaid taxes)
  • Tax evasion and fraud (incl. reporting obligation for money laundering of predicate tax offences)
  • Tax and VAT audits (domestic and jointly with foreign tax authorities)
  • Tax controversy and overview of the remedies for taxpayers to challenge tax assessments and penalties
  • Tax reporting and exchange of information (automatic, on request, spontaneous)
  • Mutual agreement procedure and arbitration (particularly for transfer pricing disputes)
  • Tax litigation in the Luxembourg courts and beyond
