Australia → Thailand · tax
In plain termsTwo machines, one remittance hinge. Thailand counts days and remittances; Australia keeps Super, CGT event I1 and Age Pension rules. The DTA sits between them — and Article 3(4) is the clause most Thai advisers skip.
There is a treaty — [1989] ATS 36
An in-force Australia–Thailand DTA exists (yes), signed 1989-08-31, entry into force 1989-12-27 on the Australian Treasury list. Compare the live beachhead pair: Australia → Vietnam · tax.
Article 3(4) — remittance shrinks relief
Client trapWhere Thailand taxes only remitted foreign income, treaty relief on the Australian side applies only to the remitted portion (yes). Thailand's residence door is 180 days in a calendar year, with foreign income taxed on remittance (yes) — read Thailand tax residency.
Dual residence — different cascade from Vietnam
If both countries call you resident, Art 4 picks one: permanent home → habitual abode → closer personal and economic relations. That is not the AU–Vietnam cascade. Adding day counts together proves nothing.
Pensions and credit
- Private pensions/annuities — taxable only in the treaty residence state (yes, Art 18), subject to government-service Art 19.
- Australia credits Thai tax on Thai-source income (yes, Art 24).
- Thailand credits Australian tax, capped (yes).
Australia-side traps — destination does not delete them
- AU residency still has a 183-day-style test (yes).
- Ceasing AU residency can trigger CGT event I1 (yes).
- DASP excludes Australian citizens and permanent residents (yes).
- Age Pension: full portable rate needs 35 years AWLR from 2014; rate may proportionalise after 26 weeks overseas.
No social security agreement
GapThere is no Australia–Thailand social security agreement (no). Portability and AWLR stay under Australian domestic rules — the income DTA does not totalise contributions.

Common questions
- Is there an Australia–Thailand tax treaty?
- Yes. [1989] ATS 36 is in force (signed 31 August 1989; Australian Treasury lists entry into force 27 December 1989). It covers dual residence, pensions, and foreign tax credit — it does not replace Australian domestic traps like CGT event I1 or Super preservation.
- How does Thailand's remittance rule interact with the treaty?
- Article 3(4) says that where one country taxes only remitted income, treaty relief in the other country applies only to the remitted slice. Thailand taxes residents on foreign income when it is brought in (Revenue Code §41). So AU relief can shrink to what you actually remit — a trap brochure sites rarely quote.
- Is the dual-residence test the same as Australia–Vietnam?
- No. AU–Thailand Article 4 runs: permanent home → habitual abode → closer personal and economic relations (citizenship is a factor in the third limb). AU–Vietnam runs permanent home → centre of vital interests. Do not copy the Vietnam cascade onto Thailand.
- Is there a social security agreement?
- No. Thailand is not on Australia's DSS list of international social security agreements. Age Pension portability and AWLR still follow Australian domestic rules.
