Australian Tax Residency When You Move to Thailand — The Key Issues
Moving to Thailand from Australia triggers a series of Australian tax consequences that many expats discover too late. When do you become an Australian tax non-resident? What happens to your Australian assets? What must you tell the ATO? These are questions for an Australian tax accountant — but this guide explains the framework so you know what to ask.
Important Disclaimer
This post is general guidance only. Australian tax residency and its consequences are highly fact-specific. Consult a registered Australian tax accountant or tax agent before taking any action. The ATO has significant audit powers — making assumptions about your residency status without professional advice is a substantial risk.
The Ato Residency Tests
The ATO uses four tests to determine whether a person is an Australian resident for tax purposes. You are a resident if you satisfy ANY ONE of:
1. The resides test (primary): you actually reside in Australia. Once you move to Thailand permanently, this test typically fails — but "permanently" is the key word. The ATO considers the totality of your circumstances: where your family is, where your home is, where your economic and social ties are.
2. The domicile test: your domicile (legal home) is Australia, unless the ATO is satisfied your permanent place of abode is outside Australia. This is the test most relevant to Australians who move to Thailand — do you have a "permanent place of abode" in Thailand? Factors include whether you have a long-term lease, how long you intend to stay, and whether you have cut ties with Australia.
3. The 183-day test: you are physically present in Australia for more than 183 days in a tax year. If you move to Thailand mid-year and return for less than 183 days, you may fail this test.
4. The superannuation test: you are a member of certain government super funds (irrelevant for most private sector Australians).
The Critical Question: When Do You Become A Non-Resident?
You become a non-resident on the date you cease to be a resident under all applicable tests. This is not a clean calendar date — it is a facts-and-circumstances judgment.
Practical indicator: the ATO generally considers you a non-resident from the date you depart Australia if:
- You have a long-term overseas address (lease in Thailand)
- You have not maintained an Australian home (sold or rented it out long-term, not reserved for personal use)
- Your family is with you in Thailand
- You do not intend to return to Australia in the short term
If you are uncertain: file your Australian tax return showing your residency status and let a tax agent determine the effective date.
What Changes When You Become A Non-Resident
Tax Rates:
Australian non-residents are taxed at the non-resident tax rates on Australian-sourced income. The first AUD 0–AUD 45,000 is taxed at 32.5% (no tax-free threshold). This is significantly higher than resident rates on the same income for low-to-moderate earners. High earners may pay similar rates.
Australian-Sourced Income:
Non-residents must still lodge an Australian tax return and pay Australian tax on Australian-sourced income: rental income from Australian properties, Australian dividends, Australian interest, and capital gains on Australian taxable property (see below).
Foreign-Sourced Income:
Non-residents do NOT pay Australian tax on foreign-sourced income. Your Thai income, overseas dividends, and offshore bank interest are not Australian taxable income once you are a non-resident. (Thai tax may apply — see the DTA.)
The Australian Home — Cgt And The "6-Year Rule"
Your family home: if you sell your Australian home after becoming a non-resident, the principal place of residence (PPR) CGT exemption is lost for the non-resident period. The 2020 changes eliminated the PPR CGT exemption for foreign residents at the time of sale.
The 6-year rule: if you rent out your Australian home and remain non-resident for no more than 6 years, the property MAY still qualify for the PPR exemption on sale — but only if you make the relevant election and do not elect the PPR exemption for another property during that period. This is complex and requires specific advice.
Notifying The Ato
You do not need to notify the ATO that you are leaving Australia. However:
- You must lodge Australian tax returns for any year in which you had Australian-sourced income, regardless of residency.
- Your first non-resident return should clearly state your date of residency change (if you changed status mid-year, you may have a dual-status return — resident for part of the year, non-resident for the rest).
- If you have PAYG withholding tax deducted from Australian income (dividends, rental), this is reconciled in your tax return.
The Australia-Thailand Dta And Double Taxation
The Australia-Thailand Double Tax Agreement (1989) prevents double taxation. Key points:
- Australian rental income: taxable in Australia; Thailand may also tax it if you are a Thai tax resident, but a credit for Australian tax paid reduces Thai liability.
- Thai employment income or business income: taxable in Thailand; generally not taxable in Australia (non-residents are not taxed on foreign income).
- Capital gains on Australian property: taxed in Australia regardless of residency.
For most Australians living in Thailand, the main Australian tax exposure is: rental income from Australian property and tax on Australian dividends.
What To Do Before You Leave
1. Engage a registered Australian tax accountant with cross-border expertise.
2. Determine your effective residency change date based on your specific circumstances.
3. Understand the CGT position on your Australian home before you go — selling before departure may be advantageous.
4. Review your investment portfolio: non-residents pay higher withholding on Australian dividends.
5. Review your superannuation arrangements — particularly if you have an SMSF.
