Leaving Australia: What to Know
Tax Departure Rules for Australia
Australia imposes a deemed disposal (departure tax) on most assets when you cease tax residency. This means unrealised capital gains are crystallised at market value on the day you leave. You can elect to defer this tax, but the gains will be calculated in AUD at the time of eventual sale.
Capital gains considerations: The CGT discount (50% for assets held over 12 months) is lost for gains accruing after you cease residency. Foreign residents also lose the main residence CGT exemption for Australian property.
Practical steps when leaving: Cancel your Medicare enrolment, notify Centrelink, and review your superannuation investment strategy. Consider the timing carefully — leaving mid-financial year creates a split-year tax situation.
