For an Australian founder, senior remote employee or HNW pensioner aged 50+, the move from Australia to Thailand can collapse a top marginal personal rate of 47% (45% income tax plus 2% Medicare levy) to an effective 0% on foreign-source income — provided you obtain a Long-Term Resident (LTR) Visa in one of its three “wealthy” categories, whose foreign-income exemption sits in Royal Decree No. 743 and explicitly overrides the post-2024 remittance reform that now bites ordinary Thai tax residents. Unlike the Australia-to-UAE corridor, this move is supported by a comprehensive Australia-Thailand Double Tax Agreement in force since 27 December 1989, with an Article 4 tie-breaker — but Australia’s CGT Event I1 deemed disposal under section 104-160 ITAA 1997 still triggers on cessation, and the LTR’s USD 80K/year income test is the constraint that screens out most candidates before the tax planning even starts.
The Tax Delta at a Glance
| Australia (current) | Thailand (after move, LTR Cat 1–3) | |
|---|---|---|
| Personal income tax | 0–45% progressive + 2% Medicare levy (top marginal 47%) + up to 1.5% Medicare levy surcharge | 0% on foreign-source income remitted under the LTR Royal Decree exemption; 5–35% on Thai-source income; 17% flat for LTR Highly Skilled Professionals |
| Capital gains tax | Taxed at marginal rate; 50% CGT discount for individuals on assets >12 months; discount denied to non-residents on TAP gains accrued post-8 May 2012 | 0% on offshore gains for LTR Cat 1–3 holders; SET-listed share gains exempt for individuals; otherwise progressive on remitted gains |
| Dividend tax | Marginal rate; franking offsets AU dividends; 15% non-resident withholding under AU-Thailand DTA Article 10 on unfranked dividends post-departure | 0% on foreign dividends remitted under LTR exemption; 10% Thai withholding on Thai-company dividends |
| Wealth / inheritance | No estate tax; CGT on death deferred for non-resident beneficiaries | No wealth tax; 5% inheritance tax on net inheritance above THB 100M (descendants); 10% (others) |
| Worldwide vs territorial | Worldwide for residents; CGT Event I1 deemed disposal on cessation | Resident-and-source, but LTR Royal Decree converts Cat 1–3 to effectively territorial for Thai tax purposes |
| Effective rate (NSW founder, AUD $1M mixed income) | ~44–47% | ~0–17% |
A NSW resident realising AUD $1M of mixed salary, fully-franked dividends and capital gains pays roughly AUD $400,000–$450,000 in combined federal income tax and Medicare levies. The same income earned cleanly through Thai LTR residency in the Wealthy Global Citizens, Wealthy Pensioner or Work-from-Thailand Professional categories — and remitted into Thailand under the Royal Decree exemption — attracts THB 0 in Thai personal tax. The catch is that Thailand’s foreign-income exemption only applies after you have ceased Australian residency cleanly and after you hold the LTR; mismanage the sequencing and you can end up paying both Australian CGT Event I1 and Thai tax on the same remittance.
Step-by-Step Move
Step 1: Confirm you can legally cease Australian tax residency
Australia uses a multi-test residency framework rather than a clean day-count rule. Four tests apply, and satisfying any one of them makes you Australian-resident for tax: (a) the “resides” test — a facts-and-circumstances common-law test of where you ordinarily live; (b) the domicile test — an Australian-domiciled person remains resident unless the Commissioner is satisfied their permanent place of abode is outside Australia; (c) the 183-day test — physical presence in Australia for 183+ days in the income year, unless the Commissioner is satisfied that your usual place of abode is outside Australia and you do not intend to take up residence in Australia; and (d) the Commonwealth superannuation fund test for certain government employees and eligible spouses.
The two tests that trip up most departing Australians are the domicile test and the resides test. Domicile is “sticky” — an Australian-born or Australian-domiciled individual retains Australian domicile by default. Taxation Ruling IT 2650 sets out the factors: intended and actual length of stay overseas, intention to return, establishment of a home overseas, abandonment of any Australian residence, durability of association with the overseas place, and continuing economic, social and family ties to Australia. Harding v Commissioner of Taxation [2019] FCAFC 29 confirmed that a permanent place of abode requires “permanence” in a meaningful sense — temporary expat assignments and serviced-apartment living do not qualify, but a settled long-term home in a single overseas country does.
For an Australia→Thailand move, the clean exit looks like: leasing or selling the Australian principal place of residence (a long-term arm’s-length lease being defensible, an “available for our return” arrangement being fatal), moving the family unit to Thailand, surrendering Medicare entitlement via Services Australia notification, cancelling Australian state driver’s licences in favour of a Thai one, closing or non-residentialising Australian bank accounts to the extent practical, and establishing a settled Thai home — typically a registered long-term lease in Bangkok, Chiang Mai or Phuket — supported by Thai utility bills, a Thai TIN and the LTR visa stamp.
Step 2: Plan around Australia’s CGT Event I1 deemed disposal
The single largest gotcha for Australians is CGT Event I1 under section 104-160 ITAA 1997: at the moment you cease to be an Australian resident, you are treated as having disposed of each CGT asset you own at its market value at the time of the event, with any resulting capital gain or loss included in your final-year Australian assessment. There is no de minimis for individuals — every share, every cryptocurrency holding, every foreign bank deposit denominated in foreign currency, every interest in a foreign trust, every foreign rental property is in scope at the moment you stop being a resident.
A category of property is excluded from CGT Event I1: Taxable Australian Property (TAP) under section 855-15 — primarily (i) direct interests in Australian real property; (ii) indirect Australian real property interests; (iii) assets used in carrying on a business through an Australian permanent establishment; and (iv) options or rights over the foregoing. TAP is not deemed-disposed because Australia retains taxing rights over it indefinitely under section 855-10, and the 50% CGT discount is denied to non-residents on the portion of TAP gains accrued from 8 May 2012 onwards under section 115-115. Obtain a market valuation at the date of departure for every TAP asset and keep it in the file for the eventual sale.
For everything else — listed Australian and foreign equities held outside super, private-company shares, crypto, foreign real estate, partnership interests, rights and options — CGT Event I1 applies. Australia provides one structural relief: under section 104-165, an individual ceasing residency may elect to disregard CGT Event I1 for any or all non-TAP assets, in which case those assets are deemed to be TAP going forward and remain in the Australian CGT net until actual disposal. The election is made on the final-year tax return and is all-or-nothing per asset. There is no security-posting mechanism (unlike Canada’s T1244 or France’s 167 bis); the election is simply a permanent extension of Australian taxing rights.
For an Australia-to-Thailand move the structuring choice is sharper than for most corridors. Thailand’s LTR foreign-income exemption is prospective from the date of LTR-holder Thai tax residency, not retroactive — gains realised before you become a Thai LTR-tax-resident are not within Thai scope, but neither are they within the LTR exemption umbrella. Crystallising at departure under CGT Event I1, paying Australian CGT with the 50% discount intact, then becoming a Thai LTR holder with a clean stepped-up cost base for future appreciation is the cleaner outcome for most Australian founders. The section 104-165 election makes sense only for low-basis growth assets you genuinely expect to dispose of after a possible Australian re-entry.
Step 3: Establish Thai tax residency and obtain the LTR Visa
Thai tax residency is the simple part: physical presence in Thailand for 180 days or more in any calendar year triggers Thai tax residency, regardless of visa class. There is no concept of domicile, no centre-of-vital-interests test under domestic Thai law (the Article 4 tie-breaker analysis is reserved for treaty disputes), and no day-count averaging across years.
The LTR layer is what unlocks the foreign-income exemption. Four LTR categories exist; three are relevant for Australian-departure tax planning:
- LTR Wealthy Global Citizens — USD 1M in assets, USD 80K/yr personal income for the past two years, and USD 500K invested in Thai government bonds, Thai FDI or Thai real estate. Foreign-income exemption applies. Best for HNW founders comfortable parking USD 500K in Thailand for the duration.
- LTR Wealthy Pensioners — Aged 50+, USD 80K/yr passive/pension income (or USD 40K–80K with USD 250K Thai investment). Foreign-income exemption applies. The natural fit for retiring Australian SMSF members and pre-retirement professionals with structured passive income.
- LTR Work-from-Thailand Professionals — USD 80K/yr from a foreign employer (or USD 40K–80K with a master’s degree / IP / Series A funding); employer is a public company or has USD 150M+ revenue over the last 3 years. Foreign-income exemption applies. The cleanest product on the market for senior remote employees of multinationals.
The LTR Highly Skilled Professionals category is the exception — it does not carry the foreign-income exemption but instead applies a 17% flat Thai personal income tax on Thai-source employment income for specialists hired into BOI-promoted Thai operations. For an Australian founder with foreign-source income, Categories 1–3 dominate.
The LTR is a 10-year permit (issued as 5+5) at a government fee of THB 50,000 (~AUD $2,200), with annual reporting only, fast-track immigration lanes, and a digital work permit included. Processing takes ~20 working days after document submission. Apply via the Board of Investment (BOI) LTR online portal. Total professional setup typically runs USD 5,000–USD 15,000 plus the category-specific investment if any. Full destination breakdown — category trade-offs, Tax Identification Number registration, banking and lease — sits on the Thailand country page.
Step 4: Document the break and the new tie
Collect contemporaneously: LTR visa stamp, Thai immigration entry log, registered Thai lease, Thai bank statements (Bangkok Bank, Kasikorn or SCB are LTR-friendly), utility bills, private health insurance (USD 50,000 minimum coverage required for the LTR), school enrolment for any dependants, Thai Tax Identification Number, and the Thai Tax Residency Certificate issued by the Thai Revenue Department once you have hit 180+ days in a calendar year. Apply early in your second Thai calendar year; the certificate is the document the ATO will look at if your departure is challenged.
Crucially, the Australia-Thailand Double Tax Agreement (signed 19 August 1989, in force from 27 December 1989) provides an Article 4 tie-breaker — a structural advantage relative to the Australia-to-UAE corridor, where no DTA exists. Article 4 of the AU-Thailand DTA resolves dual residency in the standard OECD sequence: permanent home → centre of vital interests → habitual abode → nationality → mutual agreement procedure. If the ATO argues you remained an Australian resident under domestic law and Thailand argues you became a Thai resident under the 180-day rule, the treaty tie-breaker applies and the case can be escalated to MAP between the ATO and the Thai Revenue Department.
The practical test is the permanent home limb. A registered long-term Thai lease in a property you actually occupy, with the Australian principal residence either sold or on an arm’s-length lease, generally lands the tie-breaker on the Thai side. A spouse and children remaining in Australia, or an Australian house kept furnished and “available,” can flip the centre-of-vital-interests analysis back to Australia even where the day-count is met in Thailand.
Step 5: First-year compliance in both jurisdictions
The departure-year Australian tax return is a part-year resident return covering worldwide income up to the date of cessation, the CGT Event I1 deemed disposal gains, the section 104-165 election if any, plus any post-departure Australian-source income at non-resident rates (no tax-free threshold for non-residents — the bracket starts at 32.5% from dollar one up to AUD $135,000). Post-departure, Australian-source income remains in the Australian net at non-resident rates — but here the AU-Thailand DTA reduces the bite: 15% withholding on unfranked dividends under Article 10 (down from the 30% statutory rate), 10% on most interest under Article 11, and 15% on royalties under Article 12. Fully-franked dividends from Australian companies are exempt from further tax for non-residents but the franking credits are not refundable.
Australian superannuation is not deemed-disposed under CGT Event I1 — super interests are not CGT assets in the ordinary sense, and the standard preservation rules continue to apply. You cannot access the balance until preservation age (60 for those born after 1964) regardless of where you live. Australian citizens and permanent residents are not eligible for the Departing Australia Superannuation Payment (DASP), which is restricted to former temporary residents. Pragmatic approach: leave the super untouched, accept that contributions cease, and plan a tax-efficient withdrawal at preservation age. Once you are a Thai LTR Cat 1–3 tax resident, super pension payments remitted into Thailand fall within the Royal Decree foreign-income exemption — Thailand takes 0%, Australia continues to apply its non-resident super pension framework.
In Thailand, register for a TIN within 60 days of the first Thai-source income or the first taxable remittance. The Thai personal tax return (PND.91) is filed by 31 March for the prior calendar year. LTR Cat 1–3 holders disclose foreign income and claim the Royal Decree exemption on the return — the exemption is not automatic on assessment, it must be claimed. Maintain a clean log of (i) physical days in Thailand, (ii) any days spent in Australia, (iii) the LTR Tax Residency Certificate file, and (iv) the source-and-date documentation for every offshore-to-Thailand remittance, since the Revenue Department’s post-2024 audit focus on remittances has materially increased.
Cost & Timeline
| Phase | Cost | Time |
|---|---|---|
| Tax planning + AU/Thai legal review (pre-move) | AUD $12,000–AUD $30,000 | 1–3 months |
| CGT Event I1 modelling, market valuations, section 104-165 analysis | AUD $10,000–AUD $30,000 | 1–3 months |
| LTR application (BOI portal, document prep, translations) | AUD $7,000–AUD $20,000 | 1–2 months |
| LTR investment (Wealthy Global Citizens only — USD 500K Thai bonds/FDI/real estate) | AUD $0–AUD $850,000 | Concurrent |
| Move + setup (lease, utilities, schooling, banking) | AUD $10,000–AUD $30,000 | 1–2 months |
| Departure-year AU return + first Thai PND.91 | AUD $6,000–AUD $18,000 | Annual |
| Total year-1 advisory cost (excl. LTR investment) | AUD $40,000–AUD $100,000 | 6–12 months |
For a NSW founder on AUD $1M mixed income, the post-move annual cash saving (~AUD $400K–$450K) typically recovers the entire setup cost within the first two months of Thai LTR residency, even before the one-off CGT Event I1 liability is netted off.
Treaty Considerations
The Australia-Thailand DTA (signed 1989, in force from 27 December 1989) is fully operative and was modified by the Multilateral Instrument (MLI) which entered into force for Thailand on 1 July 2022 and for Australia on 1 January 2019. The MLI inserts a Principal Purpose Test (PPT) under Article 7, denying treaty benefits where one of the principal purposes of an arrangement was obtaining the benefit. For a substantive relocation — family move, settled Thai home, surrender of Australian residential ties — the PPT is unproblematic; for a “paper” move designed primarily to access the LTR exemption, it is a real risk.
Article 4 tie-breaker mechanics work in standard OECD sequence: permanent home → centre of vital interests → habitual abode → nationality → MAP. The withholding rates that matter post-departure: dividends 15% under Article 10 (cf. 30% statutory non-resident rate), interest 10% under Article 11 (the 25% rate applies in narrow non-financial-institution cases), royalties 15% under Article 12. Pension and superannuation income is generally taxable only in the country of residence under Article 18, with the source-state retaining limited rights — meaning that once you are demonstrably Thai LTR-resident, Australian-source pension flows into Thailand benefit from both Article 18 of the treaty and the LTR Royal Decree exemption.
Both Australia and Thailand are CRS signatories. UAE-style information opacity does not exist here — Thai financial institutions report account holdings of Australian-resident persons to the ATO via the Thai Revenue Department, and vice-versa, automatically each year. Plan on full information transparency.
Common Mistakes
- Triggering Thai tax residency before the LTR is approved. A common pattern: move to Thailand on a tourist or DTV visa, hit 180 days, then apply for the LTR. The result is a partial calendar year as a Thai resident without the Royal Decree exemption — meaning foreign income remitted in that period is taxable under post-2024 reform rules. Sequence: LTR approval first, then the move, then the day-count.
- Leaving the family in Australia. A spouse and minor children remaining in an Australian dwelling is a near-fatal residential tie under both the resides and domicile tests, and it shifts the Article 4 centre-of-vital-interests tie-breaker back to Australia even where the Thai day-count is met.
- Treating the Australian principal residence as “available.” A house kept furnished, vacant and ready for the family’s return defeats both the IT 2650 / Harding permanent-place-of-abode-overseas test and the treaty permanent-home tie-breaker. Sell, or put it on a 12-month-plus arm’s-length lease.
- Failing the LTR USD 80K income test. The LTR is screened on a hard income floor for two prior years (Cat 1, 2, 3). Australian founders mid-build whose income has been deferred into retained company earnings often fail this gate. Plan declarations and dividends to cross the threshold before applying.
- Forgetting to claim the Royal Decree exemption on the Thai return. The LTR foreign-income exemption is not automatic on assessment — it must be claimed on the PND.91 with supporting documentation tying the remittance to qualifying foreign income. Unclaimed remittances default to the post-2024 taxable treatment.
- Defaulting into the section 104-165 election by accident. The election is made by ticking a box on the Australian departure return. It is permanent. Review with an Australian-registered tax agent before lodging — the wrong choice can either trigger an avoidable cash tax bill or trap an asset in the Australian CGT net for life.
FAQ
Will I still have to file in Australia after moving?
Yes, in two scenarios. (1) The departure-year Australian tax return covers your worldwide income up to the date of cessation, the CGT Event I1 deemed disposal gains, the section 104-165 election if any, plus post-departure Australian-source income at non-resident rates. (2) Continuing Australian-source income — rental from retained Australian real estate (taxed at non-resident rates from the first dollar; no tax-free threshold), Australian-source business income, royalty income, and CGT on the eventual disposal of TAP — generally requires an annual non-resident return. The AU-Thailand DTA reduces withholding rates from 30% to 15% on dividends, statutory to 10% on interest, and to 15% on royalties.
Can I keep my Australian bank account, super and property?
Yes to all three. Banks reclassify the account as non-resident, applying 10% non-resident interest withholding (treaty rate). Australian super stays in place and remains tax-advantaged — preservation rules continue, contributions cease when employment income ceases, and access is restricted to preservation-age conditions. Citizens and PRs cannot use DASP. Australian real estate can be retained but the 50% CGT discount is denied on the portion of the gain accruing from 8 May 2012 onwards in non-resident periods, and the main residence exemption is largely denied to foreign residents under the post-30 June 2020 rules — selling the principal residence before departure typically preserves an exemption that a post-departure sale will lose.
Does the LTR Visa make me automatically a Thai tax resident?
No. Thai tax residency is triggered by 180+ days of physical presence in a calendar year, regardless of visa status. You can hold the LTR and still be non-resident for Thai tax purposes if you spend less than 180 days per year in Thailand. For most Australia-to-Thailand departures the goal is exactly the opposite — you want to become a Thai LTR-tax-resident, because that is what unlocks the Royal Decree foreign-income exemption and the Article 4 treaty tie-breaker that defends your Australian non-residency.
What about crypto and foreign brokerage accounts?
Both are within scope of CGT Event I1 at the moment of Australian cessation — at the prevailing market price on the day of cessation, regardless of liquidity. Many Australian crypto founders model only their listed shares and are blindsided by the deemed disposal of token holdings. Once you are a Thai LTR Cat 1–3 holder, foreign crypto and foreign brokerage gains realised after Thai tax residency starts are within the Royal Decree exemption when remitted. Trades on Thai-regulated crypto exchanges, and gains realised after becoming a Thai tax resident on Thai-source assets, are taxed under standard Thai rules — verify with the Thai Revenue Department, as guidance has been evolving.
What if the ATO disputes my departure?
The dispute typically begins with an ATO query on the departure-year return, can escalate to a residency review, and ultimately to objection, the Administrative Appeals Tribunal and the Federal Court. The AU-Thailand DTA is the structural difference compared with the UAE corridor: Article 4 mutual agreement procedure is available, and the case can be escalated to MAP between ATO and the Thai Revenue Department. The Thai Tax Residency Certificate, registered Thai lease, LTR visa stamp, family-relocation evidence, principal-residence sale or arm’s-length lease, and a clean physical-days log are the spine of the file.
Can I move back to Australia later?
Yes. There is no minimum non-residence period. If you re-establish residency under any of the four tests, you become Australian-resident again on that date, with a new acquisition cost equal to fair market value on the day of becoming resident for assets that were previously deemed-disposed under CGT Event I1 (under the corresponding section 855-45 step-up). Assets in respect of which you elected under section 104-165 to disregard CGT Event I1 retain their original cost base on re-entry. Most cross-border advisors recommend a minimum 3–5-year non-residence horizon to avoid ATO arguments that the departure was not “genuine.”
