Moving to Australia with a UK Rental Property: The Tax Pathway

For a UK landlord, Australia is the opposite of Dubai in the one variable that matters most for double tax planning: Australia has a fully functional personal income tax system that charges its residents on worldwide income. The 2003 UK-Australia Double Tax Convention does the work it was designed for, with real tax on both sides of the treaty and a credit mechanism (the Australian Foreign Income Tax Offset, FITO) that actually relieves real double tax rather than running idle against a zero foreign liability. The arithmetic is more complex than the Dubai pathway but, in many cases, the combined tax cost is similar because Australia would be charging the higher rate anyway.

This page covers the Australia-specific pieces: the four ATO residency tests and where the 'resides' test lands first, the symmetric treaty mechanics for UK rental income, how FITO actually works in practice, the temporary resident concession that can carve UK rent out of Australian tax entirely for visa-holders, the 50% CGT discount denial trap for non-resident periods under TLA (2012 Measures No. 4) Act 2013, and the tax-year mismatch that creates reporting headaches. One anonymised scenario (Helen, a UK marketing director taking a six-year Sydney secondment from 1 March 2026 with two Bristol BTLs retained) carries the figures through.

The symmetric UK-Australia treaty

The 2003 Convention between the UK and Australia entered into force on 17 December 2003 and has effect from 1 April 2004 (UK Corporation Tax) and 6 April 2004 (UK Income Tax and Capital Gains Tax). The Multilateral Instrument modifications took effect from 1 January 2019 (withholding tax) and 6 April 2020 (Income Tax and CGT). The treaty broadly follows OECD model architecture: Article 4 residence tie-breaker, Article 6 income from immovable property (situs jurisdiction taxes), Article 13 capital gains on immovable property (situs jurisdiction taxes), and Article 22 elimination of double taxation by credit method.

The substantive difference from the Dubai case is that both sides of the treaty have a tax to allocate. UK keeps primary taxing rights on UK rental income under Article 6. Australia taxes its residents on worldwide income including the UK rent (with the FITO credit for UK tax paid). The treaty allocates, the credit relieves, and the combined burden is the higher of the two domestic systems on the same slice of income.

For the Australian-resident UK landlord this means UK rental income runs through two parallel computations every year: the UK return (income tax less section 24 reducer less personal allowance) and the Australian return (worldwide income including UK net rent, FITO credit for UK tax paid). The temporary resident concession (covered below) can short-circuit the Australian side for visa-holders during the eligible period.

The four ATO residency tests

Australian tax residence under section 6(1) of the Income Tax Assessment Act 1936 is determined by four alternative tests; meeting any one makes the individual an Australian tax resident.

The 'resides' test (common-law, primary). The individual resides in Australia in the ordinary sense of the word. The ATO weighs physical presence, intention, family and business ties, social and living arrangements, maintenance of an Australian home, schooling arrangements for children, location of assets, and behaviour patterns. For a UK landlord taking a multi-year secondment with family relocating, schools chosen, Australian home leased or bought, the resides test is normally met from arrival.

The domicile test (statutory). The individual is domiciled in Australia (broadly the country of permanent home as a matter of general law) unless the Commissioner is satisfied that the individual has a permanent place of abode outside Australia. For UK landlords, domicile typically remains in the UK on relocation; the test is more relevant on the way back out.

The 183-day test (statutory). The individual is in Australia for more than 183 days in the income year. There is a carve-out where the Commissioner is satisfied that the individual's usual place of abode is outside Australia and there is no intention to take up residence. UK landlords on extended secondment normally fall within the 183-day test but the resides test will already have made them resident.

The Commonwealth superannuation fund test. The individual is a member of a Commonwealth Superannuation Scheme (CSS), the Public Sector Superannuation Scheme (PSS), or the spouse or child under 16 of such a member. Rarely engaged for UK private-sector landlords.

The 'resides' test is the operational gate for the typical UK landlord on a multi-year Australian assignment. Determining residence precisely matters because Australian tax sits on worldwide income from the date of residence and the FITO credit only relieves UK tax against Australian tax on the same income in the same Australian year.

How Australia taxes your UK rental income (FITO mechanics)

The Australian-resident UK landlord computes UK rental income for the Australian return on Australian rules, in AUD, for the Australian tax year (1 July to 30 June). The starting point is gross UK rent received, translated at the ATO-published exchange rate or daily rate. UK allowable expenses (repairs, agent fees, insurance, allowable mortgage interest under Australian rules, depreciation under Division 40 for fixtures and the diminishing-value method) are deducted to arrive at Australian taxable net rental income.

Australian rules on rental expense deductibility differ from UK rules in several ways:

• Mortgage interest is fully deductible in Australia (no equivalent to UK section 24 restriction). The Australian computation therefore typically shows a lower net rental profit than the UK computation for the same property in the same year.
• Capital allowances on plant and fittings run on Australian Division 40 / Division 43 lines (capital works deduction at 2.5% per year on building cost, separate from fixtures). The UK capital allowance position is not portable.
• Loss treatment differs: Australian rental losses are quarantined and apply against future rental income unless the individual passes the "carry-on a business" test, which is rare for one or two properties. UK rental losses carry forward against future UK rental income only.

The UK rental net profit (after section 24 add-back) is reported on the SA105, with section 24 basic-rate reducer applied. The same UK property is reported separately on the Australian return on Australian rules. The FITO claim under Division 770 ITAA 1997 credits the UK tax paid on the rental income against the Australian tax on the same income, capped at the Australian tax that would arise on that slice of income (the FITO cap).

Practical FITO mechanics:

• The FITO cap means UK tax above the Australian tax on the same income is not refundable; it is lost as Australian credit.
• FITO is claimed on a paid basis in the Australian year (with the small business carve-out at AUD 1,000 of foreign tax allowing accrual-basis claim).
• The mismatch of tax years means UK tax paid in (say) UK 2026/27 will straddle Australian years 2026/27 and 2027/28; allocation is by reference to the underlying income period.
• Where the Australian tax on the rental income exceeds the UK tax on the same income, the excess Australian tax is the additional cost from being Australian-resident.

The temporary resident concession (section 768-910 ITAA 1997)

Section 768-910 of the Income Tax Assessment Act 1997 provides a substantial exemption for foreign-source ordinary income and most capital gains for individuals who are 'temporary residents' of Australia. The definition requires:

• The individual holds a temporary visa under the Migration Act 1958 (for example, the subclass 482 Temporary Skill Shortage visa, common for UK professionals on Australian secondment).
• Neither the individual nor their spouse is an Australian resident under the Social Security Act 1991 (broadly, neither holds an Australian permanent visa, citizenship, or qualifying status).

While both conditions are met, the individual is a 'temporary resident' for the purposes of section 768-910. Foreign-source ordinary income (including UK rental income) and most foreign capital gains are exempt from Australian tax. Australian-source income remains taxable as normal. UK interest, dividends and rental income flow through the period without Australian tax.

The concession does not apply to:

• Permanent visa holders (subclasses 100, 186, 189, 190, 491-leading-to-191, and similar).
• Australian citizens.
• Individuals whose spouse holds Australian permanent status, regardless of the individual's own visa.
• Foreign employment income (this is taxable in Australia even for temporary residents, subject to FITO for foreign tax paid).

Practical consequence for the UK landlord on Australian secondment: a four-year 482 visa with no spousal permanent status removes UK rental income (and most other foreign income) from Australian tax for the visa period. The UK side of the analysis still runs in full, but the Australian return shows only Australian-source employment income. FITO becomes irrelevant for the rental income during the concession period because there is no Australian tax to credit against.

The trap is the transition from temporary to permanent status. The moment the individual or spouse obtains a permanent visa, the concession ends from the date the permanent status is granted, and worldwide income (including UK rental) enters Australian tax. Couples planning a permanent settlement after an initial secondment need to model the date carefully.

CGT: UK NRCGT, Australian CGT, and the 50% discount denial

Disposal of a UK rental property by an Australian-resident UK landlord triggers tax in both jurisdictions, with FITO credit relief on the Australian side.

UK side: NRCGT. TCGA 1992 section 1A applies to non-resident disposals of UK land. Residential property is taxed at 18% / 24% on the gain from 6 April 2015 (rebasing default) or 18% / 24% on the full gain (election). 60-day reporting and payment from completion. The £3,000 Annual Exempt Amount (2026/27) is available for non-resident individuals.

Australian side: full ATO CGT assessment. The disposal is a CGT event A1 under section 104-10 ITAA 1997. The Australian taxable gain is computed in AUD using ATO rates: AUD acquisition cost (translated at acquisition date rate), AUD disposal proceeds (translated at disposal date rate). The gain in AUD is included in Australian taxable income at full rates (top marginal 45% plus 2% Medicare levy).

The 50% CGT discount and its denial for non-resident periods. Australian residents who hold a CGT asset for more than 12 months are entitled to a 50% discount on the resulting gain under section 115-25 ITAA 1997. Tax Laws Amendment (2012 Measures No. 4) Act 2013 Schedule 7 amended section 115-105 to remove the 50% discount for the portion of ownership when the individual was a non-resident of Australia after 8 May 2012. The discount is apportioned to:

• The pre-9-May-2012 ownership period (full discount, regardless of residence).
• The post-8-May-2012 ownership period during Australian residence (full discount).
• The post-8-May-2012 ownership period during non-Australian-residence (no discount).

For a UK landlord who bought the rental in (say) 2018, the entire ownership period to the date of becoming Australian-resident is post-8-May-2012 non-resident time. The discount applies only to the Australian-residence portion of ownership going forward. A property bought in 2018, becoming Australian-resident in 2026, sold in 2032 has 8 years of non-resident pre-Australian-residence + 6 years of Australian-residence, giving 6/14 of the post-12-months gain at 50% discount and 8/14 at full rate. The discount denial is the most expensive Australian-side CGT trap for relocated UK landlords and is frequently missed.

FITO on the disposal. The UK NRCGT paid on the disposal is creditable under Division 770 against the Australian CGT on the same gain. The cap on FITO is the Australian tax on the gain calculated on Australian rules. Where Australian CGT exceeds UK NRCGT (commonly the case at top Australian rates with discount denial reducing the discount benefit), the Australian top-up is the additional Australian cost.

The tax year mismatch and reporting cadence

UK tax year: 6 April to 5 April. Australian tax year: 1 July to 30 June. The 87-day overlap creates several practical reporting wrinkles.

• UK rental income for 6 April 2026 to 5 April 2027 is reported in the UK SA on the 2026/27 return (filed by 31 January 2028 online).
• The same rental income split into Australian years: 6 April to 30 June 2026 in the Australian 2025/26 year; 1 July 2026 to 5 April 2027 in the Australian 2026/27 year.
• FITO claims for UK tax paid in UK 2026/27 are matched to the underlying rental income period, then allocated across the two Australian years it falls in.
• Practical workaround: most preparers cut the UK rental ledger to the Australian year-end (30 June) for the Australian return, separately from the UK April year-end ledger for the SA. The two ledgers reconcile annually.

The Australian return is due by 31 October following the year-end for self-preparers, or by the registered tax agent deadline (typically May the following year) where a registered tax agent files. The UK 60-day NRCGT return runs to a tighter clock than either annual return.

Worked example: Helen, six-year Sydney secondment from 1 March 2026

Helen, 38, UK national, marketing director on an international assignment. She owns two Bristol BTL flats acquired in 2018: Flat A (base cost £220,000, current value £290,000), Flat B (base cost £195,000, current value £255,000). Combined gross rent £30,000 per year; non-finance expenses £5,000; mortgage interest £11,000. She accepts a six-year Sydney secondment from 1 March 2026 on a 482 visa, AUD 220,000 salary, single, no Australian spouse on permanent visa.

UK side residence 2025/26. Split-year Case 1 from 1 March 2026 (start of full-time overseas work). She is UK-resident 6 April 2025 to 28 February 2026, non-resident 1 March 2026 to 5 April 2026, and non-resident for the full 2026/27 and following UK years (third automatic overseas test met).

UK rental tax 2026/27 (first full non-resident year):

• Gross UK rental: £30,000.
• Non-finance expenses: £5,000. Profit pre-finance: £25,000.
• Section 24: mortgage interest £11,000 not deductible. UK taxable rental: £25,000.
• Less UK personal allowance (UK national, retained): £12,570. Net taxable: £12,430.
• Tax at basic rate 20% (no other UK income lifting her into higher rate): £2,486.
• Less 20% basic-rate reducer on £11,000 interest: £2,200.
• UK income tax on UK rental: £286.

Australian side: temporary resident concession applies. Helen holds a 482 visa, no Australian spouse on permanent visa. Section 768-910 ITAA 1997 makes her a temporary resident for the secondment period. UK rental income is exempt from Australian tax under the concession. Her Australian return shows only her Sydney salary (AUD 220,000) at full Australian rates plus 2% Medicare levy (she is entitled to Medicare under the Reciprocal Health Care Agreement). No FITO claim needed for the rental because no Australian tax to credit against.

Year 5: contract extended permanently, partner spouse obtains permanent visa. Suppose at the start of Australian year 2030/31 (1 July 2030) Helen's partner obtains a subclass 100 permanent visa. The temporary resident concession ends from that date. From 1 July 2030 onwards, Helen's UK rental income enters Australian tax. The arithmetic for Australian 2030/31:

• UK rental net for the Australian year (translated AUD): approximately AUD 47,000 of net rental income after UK and Australian allowable deductions (Australia allows mortgage interest in full, raising the Australian net rental above the UK section-24-adjusted net rental).
• Combined with Helen's AUD 240,000 salary: top marginal rate of 45% plus 2% Medicare on the rental slice.
• Australian tax on the UK rental slice: approximately AUD 22,000.
• UK tax actually paid on the UK 2030/31 rental income (translated AUD): approximately AUD 540 (the £286-equivalent net UK liability).
• FITO credit: AUD 540 against the Australian AUD 22,000. Net additional Australian cost on UK rental for the year: AUD 21,460.

The temporary resident concession was worth roughly AUD 21,000 per year while it applied. The spouse's permanent visa transition is the costliest single event in the entire pathway.

Year 7: Helen sells Flat A in March 2032 after returning to the UK. Sale price £340,000, acquired 2018 at £220,000. Gain £120,000. NRCGT does not apply (she is UK-resident again at disposal). UK CGT in normal regime: £120,000 less AEA (£3,000), at 24%: roughly £28,080. Australian CGT applies on the post-departure-from-Australia gain only (CGT event I1 election was made on departure to defer); she has been non-Australian-resident since the return date, so the post-return portion is outside Australian CGT, but the pre-departure portion of the gain (held for 6 years 4 months as Australian resident, of which 4 years were on temporary visa with concession) is brought back into Australian CGT, with the 50% discount apportioned only to her Australian-residence days post-8-May-2012. The Australian CGT on Flat A is computed on the deemed AUD acquisition cost from the I1 election (market value at the date she became Australian-resident in March 2026) to the AUD market value at her departure date (the I1 event point), or to the actual disposal value if the I1 election was made. With the discount apportioned (4 years concession period at full discount on the temp-resident foreign asset, plus 2 years post-concession at discount), the Australian CGT on her share of the gain is roughly AUD 18,000 to AUD 22,000 depending on exchange-rate movement. The UK CGT (translated AUD) is creditable; the Australian top-up is the additional cost.

Section 10A consideration on return. Helen has been non-UK-resident for 6 complete tax years (2026/27 to 2031/32), exceeding the 5-year threshold. Section 10A does not engage. The temporary non-residence 5-year recapture page covers the rule in full. The six-year secondment is the clean break from s.10A.

Common Australia-pathway misconceptions corrected

"The UK-Australia treaty exempts my UK rental income from UK tax." Wrong. Article 6 of the treaty allocates primary taxing rights on immovable property income to the country where the property is situated. UK rental income is taxable in the UK in full; the treaty does not exempt it. The treaty's role is to allow Australian credit for the UK tax paid, not to remove UK tax.

"As an Australian resident I just pay Australian tax on my UK rent." Wrong. Both jurisdictions tax the rent. UK first (under section 264 ITTOIA 2005 and NRL scheme), Australia second (under worldwide income inclusion). FITO credits the UK tax against the Australian liability, but the taxpayer still files in both places and the higher of the two effective rates becomes the combined cost. The temporary resident concession is the only mechanism that removes the Australian layer entirely, and only for visa-holders without a permanent-resident spouse.

"The 50% CGT discount applies to my UK rental gain because I'm Australian-resident at sale." Partially wrong. The discount is apportioned to the days of Australian residence after 8 May 2012, not the position at sale. A UK property bought in 2018 by a UK resident, becoming Australian-resident in 2026, sold in 2032 has 8 years of pre-Australian-residence (post-8-May-2012) where the discount is denied, plus 6 years of Australian-residence where it applies. The non-resident days dominate and the effective discount on the total post-12-month gain is well below 50%.

"The temporary resident concession lasts forever." Wrong. The concession applies only while the individual holds a temporary visa and neither they nor their spouse holds Australian permanent-resident status. The moment either condition fails, the concession ends from that date. Most landlord-secondments using the concession see it end either at visa expiry, on transition to a permanent visa (subclass 186, 189, 190, etc.), or on a spouse obtaining permanent residence.

"My UK personal allowance is lost when I become Australian-resident." Wrong (for UK and EEA nationals). The personal allowance is preserved by UK domestic law for UK nationals regardless of where they reside. The £12,570 (2026/27) allowance applies to UK rental income, often eliminating the UK tax on a modest portfolio after the section 24 basic-rate reducer has done its work.

"I should sell my UK rental before moving to Australia to avoid the discount denial." Sometimes, but not always. NRCGT will apply if the disposal happens after non-residence is established (the pre-departure split-year case may keep the disposal in UK-resident time if timed before the split date). A UK-resident sale before departure is in normal UK CGT (18% / 24%, with the AEA), with no Australian dimension. The decision depends on the size of the unrealised gain, the discount that would be lost to denial, and the period over which the discount-eligible Australian residence would otherwise accumulate. Modelling both pathways before the move is the disciplined approach.

"NRCGT doesn't apply because I'll pay Australian CGT instead." Wrong. NRCGT under TCGA 1992 section 1A is a UK obligation independent of any Australian tax position. The 60-day return and payment must happen regardless of the Australian treatment. FITO on the Australian side credits the UK NRCGT, but the UK filing and payment is a separate cycle on a tighter clock.

Sequencing the Australia pathway

Three phases, each with parallel UK and Australian obligations.

Pre-departure. SRT planning for the departure year, P85 filing on departure, NRL1 application to receive UK rent gross, sell-or-hold modelling on the UK home and on any UK rental with a large unrealised gain (50% discount denial calculation), Australian visa class confirmation (482 vs 186 vs spouse status) and temporary resident concession eligibility. The 12-month pre-departure checklist is the operational scaffold; the SRT decision tree covers the UK residence test.

During Australian residence. Annual UK SA return on the SA100 / SA105 / SA109; annual Australian return with FITO claim (unless temporary resident concession applies); NRL6 reconciliation; NRCGT 60-day returns on any UK land disposals during non-residence; CGT event I1 election decision on any departure from Australia; ongoing day-count discipline if periodic UK trips happen. The split-year treatment page covers the Case 1 mechanics for the departure year.

Return to the UK. Section 10A 5-year recapture exposure (clean break at 6+ years of non-UK residence); split-year arrival case analysis (Cases 4 / 6 / 8); Australian I1 election position on remaining CGT assets; UK rental income tax returns to normal SA pattern with NRL1 cancellation. The companion Dubai pathway page covers the asymmetric-treaty contrast for comparison; the expat property income obligations pillar ties the broader picture together.

Australia is the textbook case of a symmetric DTA: both sides have a tax, the credit machinery relieves real double tax, the temporary resident concession provides a four-year shield for visa-holders, and the 50% CGT discount denial is the most expensive single trap. The combined burden is generally close to the Australian top rate on rental income, with UK tax effectively absorbed by FITO during the post-concession period. The decision to move to Australia is rarely tax-driven; the question is whether the UK rental should be held, sold, or restructured before the pathway begins.
