Why your tax residency status matters more than almost any other factor when you move overseas — and how to think about it.
Tax residency is one of the most important — and most misunderstood — concepts for Australians living or working overseas. Your tax residency status for Australian expats determines which country has the primary right to tax your income, how your investments and property are treated, and what reporting obligations you have. Importantly, this is a legal and tax question that sits with the Australian Taxation Office (ATO) and your tax agent — but it has flow-on effects for almost every part of your financial plan, which is why we always factor it into the advice we provide.
The ATO applies several tests to determine residency, including where your "domicile" is, how many days you spend in Australia, and the strength of your ties to Australia (family, assets, employment). There's no single factor that decides it — it's based on the whole picture of your circumstances, and the rules can produce results that surprise people who assume that simply living overseas makes them a non-resident.
Your residency status can affect:
If you own property in Australia and become a non-resident, the capital gains tax (CGT) treatment can change significantly — including the loss of the main residence exemption in some circumstances for non-residents at the time of sale. Non-resident CGT on Australian property is a common trap for expats who plan to sell a former home while living overseas, and the rules have changed more than once in recent years. This is a question to raise with your tax agent well before you sell.
Australia has tax treaties — double taxation agreements (DTAs) — with many countries, designed to prevent the same income being taxed twice. How a double taxation agreement between Australia and your country of residence applies depends on the specific treaty and the type of income involved (employment income, pensions, investment income, and so on). DTAs can also include "tie-breaker" rules that help determine residency if you'd otherwise be considered a resident of both countries.
Some people genuinely have ties strong enough to be considered a tax resident of both Australia and another country at the same time. Dual residency financial planning usually involves working through the relevant DTA's tie-breaker tests with your tax adviser, and then building your investment, super and insurance strategy around the residency outcome — rather than the other way around.
Tax residency determinations are made by the ATO and your registered tax agent — we're financial advisers, not tax agents. What we can do is help you understand how each possible outcome affects your broader financial plan, and work alongside your tax adviser to coordinate everything.
Speak to your tax agent before listing the property. Non-resident CGT rules can significantly change the tax outcome compared to selling while an Australian resident, and timing can matter.
It can affect contribution eligibility and the tax treatment of withdrawals. See our Guide to Superannuation for Australian Expats for more.
