The Special Tax Inspectorate (STI) cannot currently make sufficient use of bank data in the fight against tax fraud. This is the conclusion of the Belgian Court of Audit in a new audit report for the Federal Parliament. The Court identified two key issues.

Second, the bank investigations are hampered by strict, sometimes cumbersome procedural rules and practical constraints.
