US Expats in Australia
~90,000 US citizens Americans live in Australia. Here's what you need to know about managing your finances, staying compliant, and making the most of the US-Australia tax treaty.
The US-Australia relationship is anchored by a tax treaty ratified in 1983 and a totalization agreement that prevents double Social Security taxation. American residents in Australia typically face an effective tax rate of 19-47%, with Australian Dollar (AUD) as the local currency. The largest US expat communities are concentrated in Sydney, Melbourne, Brisbane, Perth and Adelaide.
Beyond US obligations like Form 1040, FBAR, and Form 8938, US persons in Australia must navigate 1 country-specific filing (detailed below) alongside the PFIC rules that affect most local mutual funds. The keys to staying compliant: track every AUD account against the $10,000 FBAR threshold, avoid local pooled investment products unless they qualify as QEFs, and reconcile foreign tax credits against the treaty rules.
