“Last year the ATO turned over 30,000 individuals with account balances totalling $25 billion to the IRS,” said Mr Berg.

“FATCA is this worldwide snitching program that is getting people turned in and making them quite nervous. The world has changed very, very quickly in the last five years”

Mr Berg said the FATCA isn’t the only agreement like this, with the OECD creating its own initiative for the automatic exchange of tax and financial information, called the Common Reporting Standard (CRS).

Atlas Wealth Management managing director Brett Evans said even countries like Panama, British Virgin Islands, Luxembourg and Liechtenstein that have traditionally been tax haven-type environments, have signed up to this reporting standard.

“As a result of that they'll be passing on data to the ATO and we've already started to see a lot of clients both domestically and internationally,” said Mr Evans.

Under this reporting standard, Mr Evans said individuals are asked by their account provider, whether it’s a bank or an investment account, if they’re a citizen of another country and if that’s the case they’ll be asked to provide their tax file number.

“Once they do that they’ve got a record of the fact that the individual is based in Denmark for example, but they are an Australian citizen, they’ll pass that information back through to the ATO,” he said.

“Even though you may not have any required lodgements with the ATO, the ATO will still be aware of what's happening.”

Interestingly, Mr Evans said the only developed country that hasn’t signed up to the reporting standard is the US.

“So virtually the United States is in the box seat, because everyone has to pass information to them by way of the FATCA agreement but they don't have to pass information back again,” he said.

“Technically speaking the US could be the last tax haven in the world from a developed country point of view because they don't have to do it.”
