Tax audits and litigation

Our assistance often starts in the administrative phase or in the context of a tax audit. During this phase, the tax authorities can request information from the taxpayer, from foreign tax authorities or from third parties, or they can levy an additional amount of tax. In our experience, the administrative phase is often key to a successful outcome of the dispute. The way a case is presented and the arguments are developed, can ultimately have a decisive impact. The administrative phase is a crucial phase to assess the position of the tax authorities and – if possible – reach a favourable settlement. 

We also assist our clients if the case continues in a judicial phase. Our experience ranges from the first tier tribunals over the courts of appeal up to the Supreme Court, in which case we can rely on our dedicated team of Supreme Court litigators. In addition, we have defended clients in tax cases before the Constitutional Court, the Council of State and the European Court of Justice.
