Swiss banking giant Credit Suisse has confirmed that its London, Paris and Amsterdam offices were contacted by local authorities for tax-related matters.

The confirmation from the bank comes after the Dutch office for financial crimes prosecution (FIOD) said that it launched raids in the Netherlands, Britain, Germany, France and Australia for tax evasion and money laundering following a tip-off about thousands of dubious accounts.

Dutch prosecutors said that they seized jewellery, paintings as well as gold ingots during the raids.

Meanwhile, the UK’s HM Revenue & Customs (HMRC) also confirmed last week that it launched a probe into suspected tax evasion and money laundering by a global financial institution and its employees.

“The first phase of the investigation, which will see further, targeted, activity over the coming weeks, is focused on senior employees from within the institution, along with a number of its customers,” HMRC said.

Neither the UK nor the Dutch authorities specifically mention the name of Credit Suisse, though FIOD said that its investigation concerns a Swiss bank.

Confirming the tax raids, Credit Suisse said it is cooperating with the authorities.

The bank said that it “applies a strict zero tolerance policy and wishes to conduct business with clients that have paid their taxes and fully declared their assets”.

“Consistent with our zero tolerance policy, we continue to work closely with the local authorities in all matters and particularly in this new case,” the bank added.
