Up to ten countries are currently conducting investigations into banks in Liechtenstein to determine whether their citizens are evading taxes.

From the IHT:

Following the lead of Germany and Britain, at least eight other countries, including the United States, said Tuesday that they were investigating whether some of their citizens were using banks in Liechtenstein to evade taxes at home.The countries involved in the investigations also threw their combined weight behind efforts to change banking secrecy rules in Liechtenstein, a principality nestled between Austria and Switzerland that has a thriving business in managing outsiders’ money.

The investigations started when German intelligence agents purchased confidential banking information from a source.

The investigation goes back to 2006, when German intelligence services paid nearly €5 million for confidential banking data to an informant, apparently a former employee of the Liechtenstein bank LGT Group.

Later, the British authorities paid money to the same person for data on British subjects who had sheltered money in Liechtenstein, and they are now investigating about 100 people in Britain, according to an official close to the inquiry who requested anonymity because the case was continuing.

The U.S. tax agency, the Internal Revenue Service, said Tuesday that it was beginning enforcement action against “more than 100 U.S. taxpayers.”

The countries that are currently investigating the data and looking for tax evaders from their own countries are Germany, the United Kingdom, Australia, Canada, France, Italy, the Netherlands, New Zealand, Sweden and the United States.

Even before authorities went to interview them, 72 people turned themselves in and attempted to settle their cases.

German prosecutors, aided by stolen bank records, began their crackdown nearly two weeks ago, when police searched the home of a prominent German executive.

Since then, 91 of the roughly 150 people so far being investigated have confessed to evading taxes, the prosecutors said. A further 72 people have turned themselves in without a visit from the authorities.

Targets in the inquiry have already paid €27.8 million, or $41.5 million, to begin settling their cases, and the German prosecutors made clear Tuesday that they expected to collect much more money before the inquiry was completed.
