The tax advisory company in Amsterdam raided by finance ministry inspectors in connection with tax evasion on Wednesday may count DJs Tiesto and Afrojack  among its clients, according to business magazine Quote.

The tax advisor, who has not been officially named, is said to be the brain behind the ‘world citizenship’ strategy to help people in the media and entertainment sectors who travel a great deal to avoid official residency in any country. And Quote’s sources said some of the big names on his books have already been questioned by officials about the case.

The advisor’s home and offices in central Amsterdam were raided on Wednesday, as were locations in Volendam and Utrecht.

He is suspected of helping his clients avoid millions of euros in Dutch taxes, the public prosecution department said in a statement on Wednesday.

‘He set up companies for his clients in tax havens like Guernsey and Cyprus and formed part of the management boards,’ the department said. However, the man did not have a licence to offer trust office services, as required by law. He also provided documents showing his clients had emigrated even though this was not the case, the statement said.
