Understanding Australian Tax Residency Status Domicile & Citizenship Before Moving Offshore

Introduction

Planning an offshore move often starts by assuming a new passport or a physical relocation will, on its own, end Australian tax exposure. Domicile, citizenship, & tax residency run on separate tracks, so renouncing citizenship does not end Australian tax residency & living overseas does not by itself change your domicile.

This article explains what each concept determines, how they interact, & where owners get caught.

Three Terms That Sound Similar But Mean Very Different Things

The Danger of Conflating Distinct Legal Concepts

An offshore move can fail before it begins when domicile, citizenship & tax residency are treated as interchangeable. Each concept serves a different purpose:

• Domicile concerns a permanent home by law;
• Citizenship describes nationality; and
• Tax residency status is assessed through specific residency tests.

For Australian business owners, this distinction affects how an international relocation is planned.

What Citizenship Actually Is & What It Does Not Determine

Defining Citizenship as a Nationality Status

For Australian business owners, citizenship is a nationality status that establishes a legal relationship with a country. It is separate from tax residency status, which is assessed for tax purposes through Australia’s residency tests rather than through passport status.

A second passport may change nationality status without changing Australian tax residency. The Income Tax Assessment Act 1936 (‘ITAA 1936‘) uses four alternative residency tests:

1. the resides test;
2. the domicile test;
3. the 183-day test; and
4. the Commonwealth superannuation fund test.

Citizenship & tax residency operate on separate tracks, so acquiring another nationality does not, by itself, change Australian tax obligations.

The Separation of Passport Status & Tax Obligations

Changing nationality does not resolve an Australian tax residency position. Renouncing Australian citizenship does not end Australian tax residency because the residency tests apply regardless of passport status.

The relevant facts may include:

• physical presence;
• intention;
• family ties;
• business or employment ties;
• assets;
• social arrangements; and
• living arrangements.

A business owner who gives up an Australian passport may still be a resident for tax purposes if one or more residency tests applies. If Australian tax residency continues, worldwide income may remain subject to Australian tax, creating a costly mismatch between the intended passport change & the actual tax residency status.

What Domicile Is & Why It Matters for Australian Tax Residency

The Legal Concept of a Permanent Home

Domicile is the place considered by law to be a person’s permanent home. It is different from ordinary residence because a person may live temporarily in one country while retaining a domicile elsewhere. Australian business owners planning an offshore move need to separate where life is temporarily based from the country treated as a permanent home.

Each person has a domicile, even without a fixed place of abode, but only one domicile exists at any point in time. Under Taxation Ruling TR 2023/1, Paragraph 58, a domicile continues until another domicile is acquired by choice or operation of law. As a result, retaining an Australian domicile can keep the domicile test relevant after departure, making the move harder to treat as a complete break from Australian tax residency.

Domicile of Origin Versus Domicile of Choice

An Australian business owner seeking a permanent home overseas cannot establish a new domicile merely by spending time in another country. A domicile of origin is attributed at birth, while a domicile of choice is acquired voluntarily through both relocation & a genuine intention to make the foreign country home indefinitely.

Acquiring a domicile of choice requires both of the following, & neither alone is sufficient:

1. lawful physical presence in a foreign country; and
2. a genuine intention to remain there permanently or indefinitely.

Paragraph 57–59 of TR 2023/1 distinguish the domicile of origin, the domicile of dependence, and the domicile of choice. A working visa or a fixed overseas assignment may not show the intention required, so a short-term move can leave the Australian domicile in place.

The Role of the Domicile Test in Assessing Residency

The domicile test can keep Australian tax residency in issue after an individual stops residing in Australia under ordinary concepts. Under section 6(1) of the ITAA 1936, a person whose domicile is in Australia is an Australian resident unless the Commissioner is satisfied that the person’s permanent place of abode is outside Australia.

The individual must show that Australian residency has been definitely abandoned & that permanent living has commenced overseas. The relevant factors include:

• the length of the overseas stay;
• the nature of accommodation;
• family or financial ties; and
• the durability of connections abroad.

A person moving between countries without a fixed or habitual place of abode may remain an Australian resident under the domicile test, leaving the tax residency status unresolved despite extended time outside Australia.

What Tax Residency Actually Is & How Australia Determines It

Taxation Rights Over Worldwide Income

Tax residency determines whether the ATO can tax income earned inside Australia, overseas, or through foreign entities. The treatment then depends on residency status:

• Australian residents are generally taxed on worldwide income.
• Foreign residents are typically taxed only on Australian-sourced income.

For Australian business owners generating income through international operations, the distinction can materially change their Australian tax return. Treating a foreign entity as separate from the individual residency position can leave overseas earnings within the Australian tax base, while foreign tax paid may be relevant through the Foreign Income Tax Offset (FITO).

The Resides Test & Evaluating Actual Behaviour

The resides test looks at actual behaviour, not passport status or stated intention alone. Under section 6(1), residency is assessed through relevant facts & circumstances, with no single factor deciding the outcome.

The ATO commonly considers:

• Physical presence & intention: how long, how often, & how continuously the individual remains in Australia, together with the purpose of that presence.
• Family & employment ties: where a spouse, children, business, or income-producing activities are based.
• Property & daily arrangements: Australian accommodation, assets, social connections, routines, & living arrangements.

Physical absence does not by itself end Australian tax residency. A business owner who continues returning to an established Australian family or social life can remain an Australian resident for tax purposes, making the residency position more difficult to sever than the physical move suggests.

The 183-Day Test & Physical Presence

The 183-day test creates a separate focus on physical presence during an income year, running from 1 July to 30 June. Under section 6(1), presence in Australia for 183 days or more can result in Australian tax residency unless the usual place of abode remains overseas & there is no intention to take up residency in Australia.

The days do not need to be consecutive, & part of a day counts as a whole day. The test considers:

• Total days in Australia: intermittent visits are added together.
• Usual place of abode: the settled home or living base outside Australia.
• Intention: whether the individual intends to make Australia a home.

Spending 183 days in Australia does not decide the position in isolation, but failing to examine the test can expose foreign income to Australian tax. Extended visits by business owners can therefore create a residency issue even where the main business base remains overseas.

How the Three Concepts Interact & Where Owners Get Caught Out

Practical Scenarios of Overlapping Legal Statuses

Australian business owners can hold one citizenship, one domicile & a different tax residency status at the same time. For example, a business owner can be an Australian citizen living abroad without being an Australian tax resident, & a non-citizen living in Australia who is a tax resident.

A second passport does not settle individual tax residency. The outcome turns on the same connection factors already covered — physical presence, family ties, business ties, assets, social arrangements, & intention.

Confusing passport status with tax residency can leave worldwide income exposed to Australian tax when the owner expected the offshore move to change the tax position.

Common Planning Mistakes Regarding Foreign Relocation

Living overseas does not by itself create a foreign domicile or an overseas permanent place of abode. As set out earlier, a domicile of choice needs both lawful physical presence in the foreign country & a genuine intention to make that country home indefinitely — neither alone is enough. Assertions about intention carry less weight where observable conduct points elsewhere.

A person who moves from country to country without a fixed or habitual place of abode may retain an Australian domicile. Paragraph 68 of TR 2023/1 states that the permanent place of abode will not be overseas where the person has not commenced living permanently in a particular country. The consequence for Australian business owners is that a mobile relocation can leave Australian tax residency in place despite lengthy periods abroad.

What to Clarify Before Making Any Offshore Move

Assessing Current Domicile & Planned Citizenship Changes

Planning a compliant move offshore from Australia requires separating domicile, citizenship, & tax residency rather than treating them as one decision. For Australian business owners, the relevant question is whether: 

• the existing domicile remains Australia;
• a domicile of choice has been established elsewhere; and
• the residency tests still produce Australian tax residency.

Treating a citizenship change as the solution can leave the underlying tax residency status unchanged. As covered earlier, renouncing Australian citizenship does not end Australian tax residency, & an Australian domicile keeps the domicile test in play unless the Commissioner is satisfied the permanent place of abode is outside Australia.

Evaluating Specific Circumstances Against the Residency Tests

A proposed move must be assessed against the individual facts across the applicable residency tests, not against a single document, travel date, or stated intention. Paragraph 10 of TR 2023/1 explains that residency for tax purposes is a question of fact based on an individual’s connection to Australia, with each case turning on its circumstances.

Evidence relevant to a permanent place of abode overseas may include:

• Stable overseas living arrangements — such as a home or year-long tenancy;
• Changed personal & financial connections — including family relocation, overseas finances, foreign tax records, or an Australian property that is sold or leased.

The risk is that a move may appear complete on paper while the evidence still supports Australian tax residency, leaving the individual exposed to Australian tax on worldwide income.

Conclusion

Citizenship, domicile & tax residency are separate concepts, each serving a different purpose in an offshore move. A passport does not determine tax residency, living overseas does not by itself change domicile, & residency status depends on the relevant residency tests, conduct & surrounding circumstances. Misreading those distinctions can leave Australian tax obligations in place despite an international relocation.
