Tax ligitation
Step-by-step support

Litigation is becoming an increasingly important part of our business, due to the tightening of tax audits and the strengthening of legislation.

Depending on the case, we provide assistance either during the audit phase or after the audit, for example by taking over from the chartered accountant for complex issues.


We assist or represent you at the various stages of the pre-litigation phase: formulation of observations, hierarchical appeals and referral to the relevant commissions.

If adjustments are maintained, we initiate litigation and refer the matter to the relevant administrative and judicial courts.

This can take us all the way to the Council of State and the Court of Cassation or the Court of Justice of the European Union.


Many cases lead us to challenge the compatibility of national law with European rules.

One of the most landmark cases we have handled was the Santander et al. case in 2012, when we acted for one of the ten investment funds involved.

In addition to challenging tax adjustments, we regularly query the legality of particular tax measures, resulting in restitution actions.

Generally speaking, taxation is governed by precise rules and an often very strict procedural framework.
This is even more so in the area of tax procedure, where there are so many pitfalls…

Hence the importance of entrusting your disputes to specialists!
