How does returning to Australia change your tax residency status?

The moment you re-establish Australian tax residency, you move from non-resident tax rates to resident tax rates, gain access to the tax-free threshold, and become liable for the Medicare Levy. The ATO applies four tests: the Resides Test, Domicile Test, 183-Day Test, and Commonwealth Superannuation Test. Residency is not automatic on landing; the ATO assesses your circumstances including intention, ties, and behaviour.

ATO Residency Test	What It Assesses	Most Relevant For
Resides Test	Ordinary course of life, habits, family, and social ties in Australia	Most returning expats
Domicile Test	Whether your domicile is Australia and you lack a permanent place of abode overseas	Long-term overseas residents
183-Day Test	Physical presence in Australia for more than half the income year	Short-term returnees
Commonwealth Superannuation Test	Membership of prescribed Commonwealth super funds	Government employees abroad

What taxes apply to foreign income once you return to Australia?

Once you re-establish Australian tax residency, Australia taxes your worldwide income. Foreign salary, rental income, business income, and investment returns earned after your residency date all become assessable. If you have already paid tax on that income overseas, the Foreign Income Tax Offset (FITO) prevents double taxation, and ODIN Tax manages FITO applications across 40+ Double Tax Agreement countries.

What are the CGT implications of returning to Australia from overseas?

Capital Gains Tax is one of the most consequential areas for returning expats. While you held non-resident status, the 50% CGT discount did not apply to your Australian assets. From 1 July 2027, new legislation replaces the 50% CGT discount with cost-base indexation; residents can still use the discount for gains accrued before that date, and foreign residents generally cannot access it. On the day you re-establish residency, you are deemed to have acquired any foreign assets at their market value on that date. Assets held for more than 12 months after that deemed acquisition date become eligible for the 50% CGT discount for Australian residents (as per ATO rules for the relevant financial year).

Situation	CGT Treatment
Australian property sold while you were a non-resident	No 50% CGT discount; 15% Foreign Resident CGT Withholding (FRCGW) applied at settlement
Australian property sold after you re-establish residency	50% CGT discount available if asset held 12+ months as a resident
Foreign assets acquired while overseas, sold after return	Cost base resets to market value on your residency start date
Foreign shares or investments	Deemed acquisition at market value on residency date; gain accrues from that point

What Medicare, super, and threshold changes apply when you return?

Three financial obligations shift the moment you become a resident again. The Medicare Levy applies (2% of taxable income for the relevant financial year). High-income earners without private hospital cover face the Medicare Levy Surcharge, which ranges from 1% to 1.5% depending on income tier. Superannuation employer contributions also apply at the current legislated rate (12% from July 2025), and salary sacrifice contributions up to AUD 30,000 per year (concessional cap for the relevant financial year) attract concessional tax treatment.

“ODIN Tax exclusively serves Australian expats and non-residents. Every process, every piece of knowledge, is built around the non-resident tax landscape, including the residency tests, CGT rules, and DTA applications that generalist accountants routinely get wrong.”

Frequently Asked Questions

When exactly does Australian tax residency restart for a returning expat?

Australian tax residency restarts on the date you re-establish sufficient ties to satisfy one of the ATO’s four residency tests: the Resides Test, Domicile Test, 183-Day Test, or Commonwealth Superannuation Test. The date is fact-specific and depends on your intention, family situation, accommodation, and employment. It is not simply the date your plane lands. A specialist tax agent reviews your specific circumstances to identify the correct date, which determines when worldwide income and Medicare obligations begin.

Do I pay tax on foreign income earned before I returned to Australia?

Foreign income earned while you were a non-resident and before your residency recommenced is generally not assessable in Australia. Only income earned after your residency start date enters the Australian tax net. The split-year treatment the ATO applies means your return must accurately identify the exact date residency resumed to avoid over-declaring or under-declaring income. This is general information only and not personal tax advice.

Can I claim the 50% CGT discount on assets I owned while I was overseas?

For assets held during a period of non-residency, the 50% CGT discount does not apply to gains accrued while you were a non-resident. For foreign assets, your cost base resets to market value on your residency start date, so only gains accruing after that date count, and the 50% discount applies to those gains once the asset has been held for more than 12 months as a resident. Australian property sold during your non-resident period attracts no 50% discount and is subject to the 15% Foreign Resident CGT Withholding at settlement.

What happens to my overseas pension or retirement savings when I return?

Foreign pension income is generally assessable in Australia once you are a tax resident, but Double Tax Agreement provisions between Australia and your previous country of residence may reduce or eliminate Australian tax on some pension types. The treatment varies significantly by country and pension structure. A registered tax agent with DTA expertise across 40+ countries, such as ODIN Tax, calculates the correct treatment and applies any available foreign income tax offsets. This is general information only.

What if I have not lodged Australian tax returns for several years while overseas?

Overdue lodgments are common among returning expats and are manageable. The ATO has amnesty and voluntary disclosure mechanisms that can reduce or waive penalties for taxpayers who come forward proactively. ODIN Tax prepares overdue and backdated tax returns across multiple years and manages ATO penalty negotiations on clients’ behalf. Failing to act before the ATO makes contact typically results in higher penalties. General information only; outcomes depend on individual circumstances.

Will I owe Medicare Levy from the day I arrive, or from the start of the financial year?

The Medicare Levy applies from the date you re-establish Australian tax residency, not from the start of the financial year. Your tax return apportions the levy accordingly. If you held private health insurance before returning, that may affect your Medicare Levy Surcharge position. The current Medicare Levy rate is 2% of taxable income (relevant financial year). High-income earners without private hospital cover pay an additional surcharge of 1% to 1.5%. This is general information only.

Do I need to report overseas assets and bank accounts when I return to Australia?

Yes. Once you resume Australian tax residency, you must declare worldwide income, including interest from foreign bank accounts, dividends from foreign shares, and income from overseas property. Australia’s foreign income disclosure obligations are enforced through ATO data-matching with overseas tax authorities. Offshore assets themselves (as distinct from income from them) have specific reporting obligations depending on type and value. ODIN Tax assists clients with foreign income declarations and ensures the correct FITO treatment is applied to avoid double taxation. This is general information only.

How does ODIN Tax differ from a general accounting firm for returning expats?

ODIN Tax exclusively serves Australian expats and non-residents. Every client, every workflow, and every area of expertise is built around the non-resident and returning-resident tax landscape. Areas where generalist accountants routinely produce incorrect outcomes, including tax residency determinations, non-resident CGT calculations, Foreign Resident CGT Withholding, and Double Tax Agreement applications, are core daily practice at ODIN Tax. ODIN Tax has served 2,300+ Australian expats across 40+ countries and holds a 4.9/5 Google rating from 400+ verified client reviews.
