“It’s an important factor to consider when you’re, say, looking to transfer money from the US, the Hong Kong, or Europe to Australia,” said Mr Colley.

“You need to work out whether the thing you’re dealing with in an overseas country meets the requirements of a superannuation fund.”

Mr Colley said the US is a good example of vehicles that “look and smell like superannuation funds” but that don’t meet the definition of a superannuation fund – that is a retirement benefit fund.

“When you have a look at the US system, things like 401(k) plans, which are a particular type of deferred benefit fund, are not a superannuation fund simply because you can get your money out of the fund, subject to a tax penalty, for education, for health, for hardship,” said Mr Colley.

“It’s not really a superannuation fund within our meaning.”

Individual retirement accounts, on the other hand, would meet the requirements of a superannuation fund in the true sense of that word under Australian rules, he said.

“In other countries, you’ve always got to go through and look at when those benefits are being provided,” said Mr Colley.

“There are a couple of nice cases there which might seem a bit old now but they really set the precedent as to what a superannuation fund is.”
