3 weeks ago, it was announced that the judicial authorities in Kortrijk (West Flanders) had started an investigation against Tom Boonen in a case involving tax evasion. Tom Boonen took up residence in the French Principality of Monaco for several years, but returned to Belgium in 2012. In Monaco, people don't have to pay any taxes on their income, on the condition that they live there permanently.
Kortrijk prosecutors are investigating whether Tom Boonen evaded Belgian taxes. It was claimed that he still owed the Belgian taxman 2 million euros. However, by settling his debts, it is possible that the investigation can be stopped altogether. No official announcements were made about the case.
