Becoming a Non-Resident: Leaving the UK, Canada and Australia Tax Nets
The short answer
Becoming non-resident for tax purposes means meeting your home country's statutory test for leaving. Absence is not the test. The UK runs a mechanical day-and-ties calculation, Canada decides it as a question of fact on residential ties, and Australia applies four tests at once. Canada and Australia also tax unrealised gains on the way out.
Leaving is an event with rules attached, not a side effect of a one-way ticket. The other half of the problem, how nomads establish tax residency somewhere new, is a separate exercise.
Why leaving works differently if you are not American
Most nomad tax content online is written for Americans and little of it transfers. According to the IRS, US citizens are subject to US income tax on their worldwide income regardless of where they reside, so for an American the question is never whether they left the net, only how much relief a treaty or exclusion buys. The closest analogue is severing domicile with a US state, which runs on the same ties-based logic and which we cover in US state tax residency for nomads.
The UK, Canada and Australia tax on residence instead. Their citizens can genuinely leave the net, but never passively: each runs its own test, and we compare those tests in how tax residency is actually decided.
One scheduling point governs everything below: the three tax years do not align. The UK runs 6 April to 5 April per GOV.UK, the Australian income year 1 July to 30 June, and Canada the calendar year.
The United Kingdom: the Statutory Residence Test
HMRC's RDR3 guidance note sets out the Statutory Residence Test, in force since 6 April 2013. It runs in three stages, in order, and HMRC applies it tax year by tax year, so non-residence is never permanent.
Stage one, the automatic overseas tests. Any one makes you non-resident outright. Per RDR3: fewer than 16 UK days in the tax year if you were UK resident in one or more of the three prior years; fewer than 46 if you were not; or full-time overseas work with fewer than 91 UK days, fewer than 31 days working more than three hours in the UK, and no significant break.
Stage two, the automatic UK tests. HMRC's first is 183 days or more. Its home test contains no half-year at all: a UK home held for 91 consecutive days with at least 30 falling in the tax year, presence in that home on at least 30 days, and either no overseas home or presence in it on fewer than 30 days.
Stage three, the sufficient ties test, which decides everyone else. HMRC names five ties: family, accommodation, work, the 90-day tie and the country tie. The country tie applies only if you were UK resident in one of the three previous tax years, so it exists specifically to catch leavers. The ties you are allowed shrink as the day count rises, and the thresholds are stricter for leavers than arrivers.
| Days in the UK | Leaver: ties that make you resident | Arriver: ties that make you resident |
|---|---|---|
| 16 to 45 | 4 or more | Non-resident under the automatic overseas test |
| 46 to 90 | 3 or more | All 4 |
| 91 to 120 | 2 or more | 3 or more |
| Over 120 | 1 or more | 2 or more |
Counting matters as much as the bands. HMRC's manual at RFIG20720 states that "days an individual is present in the UK at the end of the day count as a day spent in the UK". The deeming rule claws some of that back: with UK residence in one of the three previous years, at least three UK ties, and more than 30 days present without being here at midnight, the days past that first 30 count too.
Split year treatment: the UK year does not split itself
A UK tax year is resident or non-resident in its entirety unless a statutory case applies. RDR3 sets out eight cases of split year treatment, cases 1 to 3 for leavers and 4 to 8 for arrivers. The two that catch departing nomads are Case 1, starting full-time work overseas, and Case 3, ceasing to have a home in the UK.
HMRC's manual at RFIG21040 lists four conditions for Case 1: UK resident for the year in question, UK resident for the previous tax year, non-resident in the following tax year because you meet the third automatic overseas test, and satisfying the overseas work criteria during a relevant period. Split year treatment is not elective — meet a case's conditions and it applies, with priority rules settling overlaps.
Because Case 1 turns on the following tax year, you leave in one year and find out whether the split worked at the end of the next. The sequencing genuinely changes the number, and it is worth paying an accountant who does cross-border work to look at your facts before you file.
Canada: residential ties, decided as a question of fact
Canada publishes no equivalent of the SRT. The Canada Revenue Agency's Income Tax Folio S5-F1-C1, Determining an Individual's Residence Status, states at paragraph 1.25 that "the residence status of an individual is always a question of fact", and at 1.10 that it "can only be determined on a case by case basis". There is no day count to pass.
What the folio supplies instead is a hierarchy. At 1.11 the CRA names three ties that "will almost always be significant residential ties": your dwelling place, your spouse or common-law partner, and your dependants. A home kept available for your own use generally stays significant while you are abroad, and at 1.12 the folio weighs an arm's length lease on its circumstances rather than treating it as clearing the tie.
Paragraph 1.14 lists the secondary ties and insists they "must be looked at collectively": personal property, social ties, economic ties, landed immigrant status or work permits, provincial hospitalisation and medical insurance coverage, a provincial driver's licence, a Canadian passport, and memberships in Canadian unions or professional organisations. None decides anything alone; together they can. That makes keeping a Canadian bank account or card part of the residency question, and worth planning alongside your nomad banking setup.
The CRA dates the change precisely: you usually become a non-resident on the latest of the date you leave Canada, the date your spouse or common-law partner and dependants leave, and the date you become a resident of the country you settle in. Separately, it deems anyone who "sojourns (that is, is temporarily present) in Canada for a total of 183 days or more" resident for the whole year under paragraph 250(1)(a) of the Income Tax Act, counting part days.
Form NR73, Determination of Residency Status (Leaving Canada), settles less than people expect: the folio says at 1.54 that departing taxpayers "should consider completing" it, then adds at 1.55 that the opinion "is not binding on the CRA". Where Canada and your new country both claim you, a treaty decides, and we work that ladder in treaty tie-breaker rules.
The Canadian departure tax
On ceasing Canadian residence, the CRA treats you as having sold certain property at fair market value and immediately reacquired it at the same amount. No sale, no cash, and the gain is still taxable. The CRA calls it a deemed disposition, reported on Form T1243 and carried to Schedule 3.
Outside it, per the CRA's guidance for emigrants, sits the "excluded right or interest" of subsection 128.1(10): Canadian real or immovable property, resource and timber resource property; Canadian business property carried on through a permanent establishment; pensions, annuities and registered plans including RRSPs, RRIFs, TFSAs, RESPs and RDSPs, plus employee security options subject to Canadian tax; and property held when you last became a Canadian resident, or inherited afterward, if you were resident for 60 months or less in the preceding 10 years.
Two thresholds get misquoted constantly. The CRA requires Form T1161, List of Properties by an Emigrant of Canada, where the total fair market value of all property owned on departure exceeds $25,000, with a late penalty of $25 per day, minimum $100 and maximum $2,500. Personal-use property worth under $10,000 is excluded from that list. Both are reporting thresholds, not exemptions from the tax.
Payment can be deferred. The CRA allows an election on Form T1244 under subsection 220(4.5) to defer the tax without interest until you actually dispose of the property, excluding employee benefit plans, due by April 30 of the year after you emigrate. Where the federal tax on that income exceeds $16,500, or $13,777.50 for former Quebec residents, it requires adequate security. All figures as of October 2026. Model this liability with a cross-border accountant before you go, not at filing.
Australia: four tests, and the one that catches leavers
The ATO applies four residency tests, set out in Taxation Ruling TR 2023/1, issued in June 2023, which consolidated and replaced the now-withdrawn rulings IT 2650, IT 2681 and TR 98/17. They are the ordinary concepts or "resides" test, which the ATO treats as the primary test; the domicile test; the 183-day test; and a test for members of certain Commonwealth government superannuation schemes. Meeting any one makes you a resident.
The 183-day test runs on the income year, 1 July to 30 June, and the ATO counts part of a day as a whole day, whether presence is continuous or intermittent. It does not apply where the Commissioner is satisfied your usual place of abode is outside Australia and you do not intend to take up residence.
The domicile test is the one that strands nomads. The ATO treats you as resident if your domicile is in Australia unless the Commissioner is satisfied your permanent place of abode is outside Australia, weighing the intended and actual length of the overseas stay, whether you established a home abroad, whether you kept an Australian residence, and your family and financial ties. The ATO says these meanings are established through case law: "permanent" does not mean everlasting or forever but is "contrasted with temporary or transitory". The Full Federal Court in Harding v Commissioner of Taxation [2019] FCAFC 29 settled a related point, holding that a permanent place of abode can be a town or country rather than one particular dwelling. The ATO's position is that someone with no fixed or habitual place of abode overseas, moving from country to country, has not adopted a permanent place of abode outside Australia. Perpetual travel is the worst available fact pattern for an Australian trying to leave.
A statutory rewrite has circled for years and is still not law. Treasury's consultation "Modernising the individual tax residency rules", open from 21 July to 22 September 2023, proposed a bright-line primary test making anyone "physically present in Australia for 183 days or more in any income year" a resident, based on the Board of Taxation's 2019 report and announced in the 2021-22 Budget. Treasury's consultation paper states that the details of the framework "have not received Government approval and are not yet law", and commentary quoting a 45-day secondary threshold is quoting that same proposal. As of October 2026 the four tests in TR 2023/1 are what the ATO applies.
Australia's exit charge: CGT event I1
Ceasing Australian residency triggers CGT event I1, a deemed disposal of your assets that are not taxable Australian property. The ATO allows a choice instead: disregard the gains and losses arising on departure, in which case those assets are treated as taxable Australian property until the earlier of a later CGT event or your becoming a resident again, with the change in value after you left counted when the gain is finally calculated.
The choice must cover all assets subject to CGT event I1 rather than a selection, and is made when you lodge the return for that income year. Taxable Australian real property stays in the net regardless of residency, and the ATO notes the full CGT discount is unavailable on assets acquired after 8 May 2012 and sold as a foreign resident.
The three systems side by side
As of October 2026, from each authority's own guidance.
| United Kingdom | Canada | Australia | |
|---|---|---|---|
| How residence is tested | Statutory Residence Test: overseas tests, UK tests, sufficient ties | A question of fact on residential ties | Four tests: resides, domicile, 183-day, Commonwealth superannuation |
| Bright-line day count | 183 days, plus tie bands at 16, 46, 91 and 121 days | Sojourners only: 183 days deems residence for the year | 183 days in the income year, subject to the Commissioner's discretion |
| Exit or departure tax | No deemed disposal on departure | Deemed disposition at fair market value | CGT event I1, with a choice to defer |
| Part-year split | Eight statutory split year cases, not elective | A dated departure, filed as an emigrant | Status changes the day you cease to be a resident |
| Key guidance or form | HMRC RDR3 | Folio S5-F1-C1; T1243, T1161, T1244, NR73 | Taxation Ruling TR 2023/1 |
What to do before you go
Each test asks for a paper trail, and none asks for it at the time.
- Dates. Log every departure and return with boarding passes and stamps. The UK turns on midnights, Australia counts part days as whole days, and Canada dates your non-residence to the latest of three events.
- A home abroad, evidenced. A lease in your name, utility accounts and a local registration do more work than stated intention, particularly against Australia's permanent place of abode test.
- Ties closed deliberately. The CRA's secondary ties list is the best checklist for all three: licences, provincial health cover, memberships, personal property.
- The tax year boundary, not the departure date. With three different year-starts, one flight sits on a different side of the line in each system.
- The exit bill, modelled first. Canada's deemed disposition and Australia's CGT event I1 are calculable before you leave.
- Social insurance, handled separately. Income tax and social security are different systems with different rules, and leaving one net does not settle the other; we cover social security and totalization agreements and what becomes of your contribution record on their own.
Landing starts the new country's proof requirements: we cover how to get a tax residency certificate and what the destination charges in our tax guide by country.
The trap of becoming resident nowhere
Leaving your home country's net does not put you inside anyone else's. The two events are independent, and plenty of nomads manage the first without completing the second.
That gap is not the win it looks like. A treaty tie-breaker needs you resident somewhere to work, banks ask for a residence declaration under common reporting rules, and a home country reviewing your departure will notice nobody else picked you up. We take it apart in can you have no tax residency, and the residency pathway options attached to nomad visas are one route into the other half of the job.
The bottom line
All three countries let you go. None lets you drift out. HMRC gives you an arithmetic problem with published thresholds and a split-year case to identify. The CRA gives you a question of fact decided on ties, plus tax on gains you have not realised. The ATO gives you four tests, a domicile question that perpetual travel actively fails, and CGT event I1 at the door.
All three care about what you did, not where you were. Treat departure as a dated transaction with evidence attached, then build a real digital nomad tax residency somewhere else.
Frequently Asked Questions
How do I become a non-resident for tax purposes?
You meet your home country's statutory test for ceasing residence. In the UK that means satisfying one of HMRC's automatic overseas tests or falling under the sufficient ties thresholds. In Canada it means severing significant residential ties, which the CRA treats as a question of fact. In Australia it means failing all four tests in TR 2023/1.
How do I become non-resident for UK tax purposes?
HMRC's RDR3 gives three automatic overseas tests, any one of which is enough: fewer than 16 UK days in the tax year if you were resident in any of the previous three years, fewer than 46 if you were not, or full-time overseas work with fewer than 91 UK days and under 31 UK working days. Otherwise the sufficient ties test decides.
How do I become a non-resident for tax purposes in Canada?
By severing residential ties. The CRA's folio S5-F1-C1 names the dwelling place, spouse or common-law partner and dependants as almost always significant, with secondary ties weighed collectively. You become non-resident on the latest of the date you leave, the date your family leaves, and the date you become resident elsewhere.
How do I become a non-resident for tax purposes in Australia?
You have to fail all four ATO tests. The hard one is the domicile test: the Commissioner must be satisfied your permanent place of abode is outside Australia, and the ATO's position is that moving country to country with no fixed or habitual place of abode overseas does not establish one. Ceasing residency also triggers CGT event I1.
What is split year treatment?
The UK mechanism that divides a single tax year into a resident part and a non-resident part. HMRC sets out eight statutory cases, three for leavers and five for arrivers. It is not optional: meet a case's conditions and it applies, with priority rules deciding overlaps.
Do non-residents still pay tax in their home country?
Usually yes, on locally sourced income and property. Canada leaves Canadian real property out of the departure deemed disposition because it stays within Canada's reach, and the ATO confirms taxable Australian real property stays subject to capital gains tax whatever your residency.
