UK-Australia Tax Treaty for UK Expats 2026 -- Tie-Breaker, Pensions and Super

Last reviewed: 26 April 2026

The UK expat tax treaty Australia (formally the UK-Australia Double Taxation Convention 2003, gov.uk/government/publications/australia-tax-treaties) is the legal framework governing how UK expats in Australia are taxed on UK-source income, and how Australian-source income is treated for UK residents. The DTC 2003 revised the earlier 1967 convention and introduced a modern OECD-aligned structure. For the UK tax residency rules that determine treaty entitlement, see our UK tax residency guide. For the full Australia relocation guide, see our moving to Australia guide.

The UK expat tax treaty Australia framework has been affected by two significant UK legislative changes from 6 April 2025: the Finance Act 2025 abolition of non-domicile status (replaced by the 4-year FIG regime for qualifying new UK arrivals who have not been UK-resident in any of the prior 10 years) and the introduction of residence-based IHT (the 10-year long-term resident rule). The ATO (Australian Taxation Office, ato.gov.au) administers Australian tax; HMRC’s International Manual (gov.uk/hmrc-internal-manuals/international-manual) covers the UK-Australia DTC 2003 interpretation. The OECD Model Tax Convention (oecd.org) provides the framework underlying the DTC. EUR/GBP is approximately 0.84 and AUD/GBP is approximately 0.51 at April 2026.

Article 4: residence tie-breaker

Article 4 of the UK-Australia DTC 2003 determines "residence" for treaty purposes where an individual is simultaneously regarded as resident in both the UK and Australia. The tie-breaker rules apply in sequence: first, the "permanent home" test (resident of the state where a permanent home is available; if in both states, proceed); second, "centre of vital interests" (state with closer personal and economic relations); third, "habitual abode" (state where the individual normally lives); fourth, nationality. For most UK nationals who have physically relocated to Australia with their family and given up their UK permanent home, the tie-breaker resolves to Australia from the date of departure. HMRC’s Statutory Residence Test (SRT, gov.uk/guidance/the-statutory-residence-test-srt) independently determines UK tax residency; the SRT result and the DTC Article 4 tie-breaker position must be considered together. A UK national who has not left the UK permanently, has a UK permanent home, and splits time between the UK and Australia may find the tie-breaker resolves to the UK even if more days are spent in Australia -- requiring careful documentation. HMRC’s RDR1 (gov.uk/hmrc-internal-manuals/residence-domicile-and-remittance-basis) covers the residency framework.

Article 18: private pension carve-out

Article 18 of the UK-Australia DTC 2003 is the pension article -- the primary source of relief for UK nationals in Australia who receive income from UK private pension funds. Article 18(1) provides that "pensions and other similar remuneration paid in consideration of past employment" are taxable only in the state of residence. For a UK national who is Australian tax resident receiving drawdown from a UK SIPP or defined benefit pension: the pension income is taxable only in Australia (at Australian marginal income tax rates, ATO, ato.gov.au) -- not in the UK. An NT (No Tax) code from HMRC’s CS&I2 team allows the UK pension provider to pay drawdown gross without UK PAYE. Key exception: Article 19 (Government Service) of the DTC -- UK government service pensions (NHS, civil service, armed forces, teachers) are taxable only in the UK, regardless of Australian residency. An NHS pension received by an Australian resident continues to attract UK income tax and UK PAYE; no NT code is available for Article 19 pensions. Australian government pensions (Australian public service superannuation) paid to UK residents are similarly treated as the paying state retaining taxing rights. HMRC’s Pensions Tax Manual (gov.uk/hmrc-internal-manuals/pensions-tax-manual) covers NT code applications and the Article 18 application.

Australian superannuation: the treaty’s critical gap

Australian superannuation (super) is the most complex UK-Australia tax treaty topic for UK-Australia mobile professionals and is not explicitly addressed by the UK-Australia DTC 2003. The DTC 2003 was negotiated before Australia’s superannuation system became the major retirement accumulation vehicle it is today. Three key positions on Australian super and the UK treaty: (1) UK employer contributions to Australian super: HMRC treats UK employer contributions to an Australian superannuation fund as a taxable employment benefit for UK tax purposes (i.e., not a deductible pension contribution). A UK national working in Australia for a UK employer who is contributing to Australian super as part of an Australian CTC package may face UK income tax on the employer’s super contributions as a "benefit in kind". The ATO at ato.gov.au publishes the Australian super framework; HMRC’s International Manual (gov.uk/hmrc-internal-manuals/international-manual) covers the HMRC position on foreign pension contributions. (2) Australian super distributions to UK residents: When an Australian national (or former Australian resident) returns to the UK and takes distributions from their Australian super fund: HMRC’s published practice has been to apply Article 18 (private pension carve-out) to Australian super accumulation-phase distributions, treating them as pension income taxable only in the UK (residence state). However, this position is not legally certain as Australian super is not explicitly defined as a "pension" in the DTC 2003; specialist UK-Australia cross-border tax advice is essential. (3) Transferring UK pensions to Australian super: Australian super funds are NOT generally on HMRC’s QROPS (Qualifying Recognised Overseas Pension Scheme) / ROPS list (gov.uk/guidance/qualifying-recognised-overseas-pension-schemes); transferring a UK SIPP or UK defined benefit pension to an Australian super fund would trigger an unauthorised payment charge of 25-55% of the transferred value under UK HMRC rules. Do not attempt UK-to-Australian super transfers without confirming ROPS status at the time of transfer.

Capital gains and the real property exception

Article 13 of the UK-Australia DTC 2003 governs capital gains. The general rule: gains from the disposal of property (including shares and other investments) are taxable in the state of residence of the seller. Key exceptions: (1) Gains from real property (real estate) sited in one state may be taxed in that state regardless of where the seller resides -- a UK national in Australia who sells UK residential property is subject to UK NRCGT (Non-Resident Capital Gains Tax, gov.uk/capital-gains-tax-for-non-residents-uk-residential-property) and must file a 60-day NRCGT return within 60 days of completion; (2) Gains from shares that derive their value principally from real property may also be taxable in the state where the real property is sited. For a UK national in Australia who sells UK shares or UK funds (not UK property): the gain is generally taxable only in Australia under Article 13. The ATO taxes Australian-resident individuals on worldwide capital gains, with the 50% CGT discount available for assets held more than 12 months (ATO, ato.gov.au/individuals-and-families/investments-and-assets/capital-gains-tax). Finance Act 2025 residence-based IHT from 6 April 2025: UK property always falls within the UK IHT estate regardless of the owner’s residency.

Finance Act 2025 IHT and the 4-year FIG regime

The Finance Act 2025 (effective 6 April 2025) introduced two changes relevant to the UK expat tax treaty Australia framework. First, the 4-year FIG regime: UK nationals returning from Australia to the UK who have not been UK-resident in any of the prior 10 consecutive tax years qualify for the FIG regime from 6 April 2025 -- their Australian income (Australian rental, Australian dividends, Australian super distributions) is outside UK tax for the first 4 tax years of UK residency, regardless of remittance. This replaces the old remittance basis. Second, the residence-based IHT 10-year rule: UK nationals who were UK-resident in at least 10 of the prior 20 tax years have worldwide IHT exposure during a tail period (up to 10 years) after departure. Australian property, Australian bank accounts, and Australian super fund balances are within the worldwide UK IHT estate for long-term UK residents within the tail. Australian superannuation death benefits paid to the estate are subject to Australian super tax rules (including the taxable component superannuation tax of 17% for beneficiaries who are not dependants under Australian law); these are separate from the UK IHT charge. HMRC’s IHT guidance at gov.uk/inheritance-tax covers the Finance Act 2025 residence-based rules; the ATO at ato.gov.au/individuals-and-families covers Australian super death benefit tax.

Dividends and interest: Articles 10 and 11

Article 10 of the UK-Australia DTC 2003 governs dividends. Dividends paid by a UK company to an Australian-resident shareholder may be subject to UK source withholding tax, capped at 15% for portfolio shareholders and 5% for corporate shareholders holding 10%+ of the paying company. Australian shareholders can claim franking credits on Australian dividends (imputation system, ATO, ato.gov.au) which offset Australian tax on the same income. Article 11 governs interest: UK-source interest paid to Australian residents is generally taxable in Australia and may be subject to UK withholding at a rate not exceeding 10%. Australian-source interest paid to UK residents is taxable in the UK and subject to Australian withholding not exceeding 10%. The DTC prevents double taxation via the foreign tax credit mechanism in each country. The UK-Australia DTC 2003 full text at gov.uk/government/publications/australia-tax-treaties is the authoritative reference for dividend and interest provisions. HMRC’s International Manual (gov.uk/hmrc-internal-manuals/international-manual) covers UK-side DTC interpretation.

FAQ

Is UK SIPP drawdown taxed in Australia for Australian residents under the treaty?

Under Article 18(1) of the UK-Australia DTC 2003 (gov.uk/government/publications/australia-tax-treaties), private pension income (including SIPP drawdown) paid to an Australian resident is taxable only in Australia -- not in the UK. To receive the SIPP drawdown gross (without UK PAYE withholding), the Australian resident must obtain an NT (No Tax) code from HMRC’s CS&I2 team specifying the UK-Australia DTC 2003 as the applicable treaty. UK government service pensions (NHS, civil service) remain UK-taxable under Article 19 regardless of Australian residency.

Can I transfer my UK pension to Australian super?

No, without significant risk of large penalties. Australian superannuation funds are not generally on HMRC’s QROPS/ROPS list (gov.uk/guidance/qualifying-recognised-overseas-pension-schemes); transferring a UK pension to an Australian super fund triggers an unauthorised payment charge of 25-55% of the transferred value under HMRC rules. Always verify ROPS status before any international pension transfer. An alternative approach -- taking pension drawdown from the UK SIPP (taxed in Australia under Article 18) and investing in Australia from the drawdown -- avoids the ROPS problem while achieving Australian asset accumulation.

Does Australian super count as a pension for UK tax purposes?

Not explicitly, as Australian super is not defined in the UK-Australia DTC 2003. HMRC’s published practice has been to treat Australian super accumulation-phase distributions as pension income under Article 18 for UK residents who receive them, but this position is not legally certain. UK employer contributions to an employee’s Australian super fund are generally treated as a taxable employment benefit (benefit in kind) by HMRC, not as a deductible pension contribution under UK rules. Specialist UK-Australia cross-border tax advice is essential for super-related planning.

How does Finance Act 2025 IHT affect UK nationals who own property in Australia?

Finance Act 2025 (from 6 April 2025) introduced residence-based UK IHT: long-term UK residents (10 of the prior 20 tax years) have worldwide IHT exposure including Australian property during a tail period (up to 10 years) after departure. Australian property, Australian bank accounts, and Australian super fund balances are all within the worldwide UK IHT estate for qualifying UK long-term residents in the tail. Australian super death benefits paid to non-dependant beneficiaries also attract Australian super tax of 17% on the taxable component -- separate from UK IHT. HMRC’s IHT guidance at gov.uk/inheritance-tax covers the new rules.

What is the 4-year FIG regime and how does it affect UK-Australia returnees?

The 4-year FIG (Foreign Income and Gains) regime (Finance Act 2025, from 6 April 2025) exempts qualifying new UK residents from UK income tax on all foreign income and gains for 4 years, provided they have not been UK-resident in any of the prior 10 consecutive tax years. A UK national returning from 10+ years in Australia who becomes UK-resident from 6 April 2025 qualifies; their Australian rental income, Australian dividends, and Australian super distributions are outside UK tax for 4 years. HMRC guidance at gov.uk/hmrc-internal-manuals/residence-domicile-and-remittance-basis.

What are the UK tax rules for UK-source dividends received by Australian residents?

Under Article 10 of the UK-Australia DTC 2003, UK dividends paid to Australian residents may be subject to a UK source withholding tax capped at 15% (portfolio shareholders, holding less than 10% of the company) or 5% (corporate shareholders with 10%+ shareholding). The Australian resident includes the gross dividend in their Australian income tax return and claims a foreign tax offset for the UK withholding tax paid. The DTC prevents double taxation; HMRC’s International Manual (gov.uk/hmrc-internal-manuals/international-manual) covers the Article 10 application. The full DTC text is at gov.uk/government/publications/australia-tax-treaties.
