Australian Superannuation: How It's Reported to the IRS

Australian Superannuation ("Super") is the mandatory retirement savings system in Australia, and US citizens participating in it face complex US tax and reporting obligations. Super funds are generally treated as either foreign pension plans or foreign grantor trusts for US purposes — the classification depends on the structure of the specific fund — and this distinction affects both how distributions are taxed and which information returns are required. Employee contributions made from pre-tax wages may be treated as taxable compensation in the year contributed on your US return (not deferred as they are in Australia), unless the US-Australia tax treaty's pension provisions provide relief. The fund itself may also need to be reported on Form 8938 if its value exceeds the threshold, and depending on its structure, on Form 3520-A as a foreign trust. The US-Australia totalization agreement may reduce the impact of double contributions to social insurance systems, but it doesn't resolve the Super fund reporting and taxation questions, which remain one of the most complex areas in US expat tax.
