In a post B.E.P.S. world, tax transparency is a mantra among stakeholders in government, media, and nongovernmental organizations. The taxpayer may own the funds, but the stakeholders wish to ensure that a chunk of the funds are spent as they deem appropriate. In this environment, governments have a stake in obtaining information on where taxpayers hold their funds and exchanges of information between governments has become a regular occurrence. In the European Union, questions arise as to whether an information request violates a taxpayer’s fundamental rights, and in the event of a fishing expedition, whether the taxpayer has an effective remedy. In a recent decision issued by the E.C.J., the court held that financial institutions holding information have rights to intervene, but not taxpayers must wait until a tax authority assesses tax. Werner Heyvaert, a partner in the Brussels Office of AKD Benelux Lawyers and Vicky Sheikh Mohammad, an associate in the Brussels Office of AKD Benelux Lawyers, explain the rationale of the court and question the validity of its conclusion.
