Ordinary residence is the legal test that decides where you habitually live, and it controls whether a country taxes your worldwide income, treats you for free in its hospitals, and lets you claim its social benefits. The concept traces back to a 1983 UK House of Lords decision and has since been adapted across Commonwealth legal systems, with each country applying its own version. It matters most at the seams between jurisdictions: when you move abroad, split time between two homes, or try to access services in a country you’ve only recently arrived in.
The Legal Definition
The foundational statement comes from R (Shah) v Barnet London Borough Council. Lord Scarman held that “ordinarily resident” refers to a person’s abode in a particular place or country “which he has adopted voluntarily and for settled purposes as part of the regular order of his life for the time being, whether of short or long duration.”1GOV.UK. Ordinary Residence Guidance The phrase “for the time being” carries weight. You don’t need to intend to stay forever. Someone who moves abroad for a three-year work contract has a settled purpose even while planning to leave.
Two requirements sit beneath the definition. The residence must be voluntary, so forced presence through detention or being stranded doesn’t count. And it must be lawful, though that principle isn’t applied uniformly across every benefit system.
The settled purpose itself can be broad. Education, employment, family, health, retirement, or a preference for a particular place all qualify. The purpose doesn’t need to be singular or specific, only stable enough that your presence isn’t casual or transient.
Ordinary Residence Versus Domicile
People often confuse ordinary residence with domicile, but they work differently. Ordinary residence describes where you actually live in a settled pattern day to day. Domicile describes the jurisdiction you treat as your permanent home, the place you would return to if all other ties fell away. You can be ordinarily resident in one country and domiciled in another.
Domicile is harder to change. Most people acquire a domicile of origin at birth (typically their father’s) and keep it until they show a clear intention to make somewhere else their permanent home indefinitely. Ordinary residence shifts more readily because it tracks your actual living pattern rather than long-term intentions. A move from Canada to Australia for a five-year posting produces Australian ordinary residence fairly quickly, but Canadian domicile usually survives unless you decide never to return.
The distinction matters for tax, inheritance, and family law. Some countries use domicile for estate tax and ordinary residence for income tax, so knowing which concept governs your situation prevents expensive mistakes.
What Authorities Actually Look At
No single fact proves ordinary residence. Officials assess the overall pattern of your life and weigh several factors together. The longer you’ve been in a country, the stronger the indication of a settled purpose. Six months of continuous presence is widely treated as meaningful, though not as an automatic trigger.2GOV.UK. Ordinary Residence Tool
Family ties carry significant weight. A spouse, partner, or children living with you in the country suggests a settled life rather than a temporary stay. Housing provides concrete evidence too. Authorities look for mortgage payments, tenancy agreements, and utility bills as signs that you’ve put down roots.2GOV.UK. Ordinary Residence Tool
Beyond the big items, officials consider secondary connections: bank accounts with regular local transactions, employment contracts, enrollment in education, vehicle registration, community memberships, and evidence of local tax payments. Each factor is a thread. None is decisive on its own, but together they show where your life is centered. The assessment is case-by-case, with no fixed formula.
How Different Countries Apply the Test
The Shah definition provides the intellectual foundation, but each country has developed its own rules. Some have codified the concept in statute, others rely on case law, and the United States doesn’t use it at all.
United Kingdom
The UK draws an important line: ordinary residence still governs access to the NHS and social care, but it no longer determines your tax status. In 2013 the UK replaced ordinary residence as a tax concept with the Statutory Residence Test (SRT), set out in Schedule 45 of the Finance Act 2013.3Legislation.gov.uk. Finance Act 2013 Schedule 45 HMRC confirmed that ordinary residence for tax “applies only to years up to and including 2012-2013.”4GOV.UK. RFIG30740 – Residence for Tax Years Before 2013-14
Under the SRT, you’re automatically UK tax resident if you spend 183 or more days in the UK during a tax year. You’re automatically non-resident if you were resident in at least one of the prior three years and spend fewer than 16 days in the UK, or if you were non-resident in all three prior years and spend fewer than 46 days. If neither automatic test applies, a sufficient ties test weighs your UK connections (family, accommodation, work, and time spent) against your days of presence.5GOV.UK. RDR3 – Statutory Residence Test SRT Notes
Another change arrived in April 2025, when the UK abolished the remittance basis of taxation. Previously, UK residents who were non-UK domiciled could choose to pay tax on foreign income only when they brought it into the country. From 6 April 2025, all UK residents are taxed on worldwide income as it arises, unless they qualify under the new four-year Foreign Income and Gains regime available to recent arrivals.6GOV.UK. INTM603655 – 6 April 2025 Non-UK Domicile Reforms
Canada
Canada’s Income Tax Act doesn’t define “resident,” so courts have filled the gap using ordinary residence principles. The leading case, Thomson v Minister of National Revenue (1946), held that residence is “a matter of the degree to which a person in mind and fact settles into or maintains or centralizes his ordinary mode of living” in a place. The Canada Revenue Agency treats someone who is ordinarily resident as a factual resident, subject to tax on worldwide income.7Canada Revenue Agency. Income Tax Folio S5-F1-C1 – Determining an Individuals Residence Status
The CRA gives the most weight to three significant residential ties: a home in Canada (owned or rented and available for your use), a spouse or common-law partner in Canada, and dependants in Canada. Secondary ties include personal property, social memberships, bank accounts, a Canadian driver’s license, and provincial health insurance. If you leave Canada but your spouse stays with the family home available, the CRA will likely still treat you as a factual resident.7Canada Revenue Agency. Income Tax Folio S5-F1-C1 – Determining an Individuals Residence Status
Canada also has a deemed resident rule: if you’re not factually resident but spend 183 or more days in Canada during a calendar year, you’re treated as resident for the whole year.7Canada Revenue Agency. Income Tax Folio S5-F1-C1 – Determining an Individuals Residence Status
Australia
Australia uses a “resides test” as its primary method for determining tax residency, which is essentially an ordinary residence assessment. The Australian Taxation Office looks at physical presence, the intention behind your stay, your behavior while in Australia, family and employment ties, asset locations, and social arrangements. The ATO treats six months as a “considerable time” for assessing whether your behavior is consistent with residing in Australia, though a shorter stay doesn’t automatically make you a non-resident if other factors point to settlement.8Australian Taxation Office. Residency – The Resides Test
If you don’t meet the resides test, Australia has three backup statutory tests: a domicile test, a 183-day test, and a superannuation test for government employees posted abroad. The system relies more heavily than the UK’s SRT on judgment about where your life is centered rather than rigid day-count thresholds.
United States
The United States doesn’t use ordinary residence as a tax concept. Instead the IRS applies two mechanical tests. The green card test makes you a US tax resident if you hold lawful permanent resident status at any point during the year. The substantial presence test makes you a tax resident if you were physically present in the US for at least 31 days during the current year and at least 183 days over a three-year period, counting all days in the current year, one-third of days in the prior year, and one-sixth of days in the year before that.9Internal Revenue Service. Substantial Presence Test
If you meet the substantial presence test but keep stronger ties to a foreign country, you can claim the closer connection exception by filing Form 8840. To qualify, you must have been present in the US for fewer than 183 days during the year, maintained a tax home in a foreign country for the entire year, and not applied for lawful permanent resident status.10Internal Revenue Service. Closer Connection Exception to the Substantial Presence Test The factors the IRS weighs (location of permanent home, family, personal belongings, social affiliations, driver’s license, and voting registration) closely mirror the ordinary residence factors used in Commonwealth countries.
Tax Consequences If You Qualify as Resident
The core tax consequence is the same across most countries: residents pay tax on worldwide income. In the US, the obligation flows from the statutory definition of gross income as “all income from whatever source derived.”11Office of the Law Revision Counsel. 26 US Code 61 – Gross Income Defined Canada taxes factual residents on income from all sources inside and outside the country. Australia taxes residents on worldwide income while non-residents pay tax only on Australian-source income. The UK now taxes all residents on worldwide income as it arises, following the 2025 abolition of the remittance basis.6GOV.UK. INTM603655 – 6 April 2025 Non-UK Domicile Reforms
Failing to report foreign income carries steep penalties. In the US, the failure-to-file penalty runs 5% of the unpaid tax for each month or partial month the return is late, up to 25%. Returns more than 60 days late face a minimum penalty of $525 for tax years with due dates after December 31, 2025.12Internal Revenue Service. Failure to File Penalty These stack on top of interest and potential accuracy-related penalties, so the cost of ignoring foreign income compounds quickly.
Treaty Tie-Breaker Rules for Dual Residents
When two countries both consider you a tax resident, double taxation agreements (most following the OECD Model Tax Convention) resolve the conflict through a sequence of tie-breaker tests. The treaty first asks where you have a permanent home available. If you have a home in both countries, it looks at where your personal and economic relations are closer, described as your centre of vital interests. If that’s inconclusive, the treaty examines where you have a habitual abode. If you spend substantial time in both, it falls back to nationality. If none of those resolve the question, the tax authorities of both countries must negotiate.
The tie-breaker analysis is fact-intensive. A home “available” doesn’t require ownership; a rented apartment you can access year-round counts. Centre of vital interests weighs family residence, employment location, business interests, and social connections as a whole. Treaty rules override domestic law for individuals covered by a relevant agreement, so your treaty position can matter as much as each country’s internal residence test.
Healthcare and Public Benefits
In the UK, ordinary residence remains the gatekeeper for free NHS hospital treatment. To receive secondary care without charge, you need to be ordinarily resident in the UK, meaning you’re living here lawfully and on a properly settled basis.13NHS. Moving to England From EU Countries or Norway, Iceland, Liechtenstein or Switzerland If you don’t qualify, hospitals can charge you 150% of the standard NHS tariff rate.14NHS. Visitors Who Do Not Need to Pay for NHS Treatment Some groups are exempt from charges regardless of residence, including refugees, asylum seekers awaiting a decision, victims of trafficking, and anyone receiving compulsory psychiatric treatment.
Ordinary residence also determines which local authority is responsible for adult social care in England under the Care Act 2014.15Legislation.gov.uk. The Care and Support (Ordinary Residence) (Specified Accommodation) Regulations 2014 If you need residential care or home support, the council where you’re ordinarily resident picks up the duty. Disputes between councils about which one bears responsibility are resolved by the Secretary of State, and they happen more often than you might expect when someone moves between areas to receive care.
US benefits work differently. The US uses immigration status categories rather than residence tests. Supplemental Security Income, for example, requires applicants to fall into a “qualified alien” category and meet additional conditions such as 40 qualifying quarters of work.16Social Security Administration. SSI Eligibility for Noncitizens Meeting the substantial presence test for tax purposes doesn’t automatically open access to federal benefits.
Foreign Asset Reporting for New US Residents
Becoming a US tax resident triggers foreign asset reporting rules that catch many new residents off guard. Two separate regimes apply, and they overlap in ways that confuse even experienced accountants.
The FBAR (FinCEN Form 114) applies if the total value of your foreign financial accounts exceeds $10,000 at any point during the year. That threshold is low enough to sweep in ordinary checking and savings accounts. The filing deadline is April 15, with an automatic extension to October 15, and penalties for willful violations are severe.17Internal Revenue Service. Report of Foreign Bank and Financial Accounts FBAR
Form 8938 (Statement of Specified Foreign Financial Assets) has higher thresholds but broader asset coverage. Unmarried filers living in the US file when their foreign financial assets exceed $50,000 on the last day of the tax year or $75,000 at any point during the year. Married couples filing jointly hit the threshold at $100,000 on the last day or $150,000 at any time.18Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets Form 8938 covers accounts, stocks, bonds, and financial instruments held through foreign institutions, while the FBAR covers accounts you have signature authority over. Many people need to file both.
Ending Your Residence Status
Leaving a country and ending your residence is often harder to prove than establishing it. Authorities are skeptical of claimed departures when residual ties remain, and the burden of proof falls on you.
The most persuasive evidence of a genuine move is eliminating the ties that created your status. In Canada, the CRA looks specifically at whether you’ve disposed of your home, moved your spouse and dependants out of the country, and closed bank accounts and credit cards. Keeping a home available for your use, even if you don’t visit it, is usually enough for the CRA to keep you as a factual resident.19Canada Revenue Agency. Determining Your Residency Status Secondary ties like club memberships, a provincial driver’s license, and stored personal property also count. The same logic applies across most jurisdictions: if your life still looks centered in the old country, telling the tax authority you’ve left won’t be convincing.
The US imposes specific departure procedures on resident aliens. Most departing aliens must obtain a “sailing permit” (a certificate of tax compliance) from the IRS before leaving. This means filing Form 1040-C or Form 2063 and scheduling an appointment at a local IRS office at least two weeks before your planned departure date.20Internal Revenue Service. Departing Alien Clearance Sailing Permit Diplomats, certain F and J visa students who earned only authorized employment income, and some short-term business visitors are exempt.
US citizens and long-term permanent residents (those who held a green card in at least 8 of the prior 15 years) who renounce citizenship or surrender their green card face an additional layer: the expatriation tax. You’re treated as a covered expatriate if your average annual net income tax over the five years before expatriation exceeds $211,000 (for 2026), or your net worth is $2 million or more on the date you expatriate, or you can’t certify five years of tax compliance. Covered expatriates are taxed as if they sold all their assets on the day before expatriation, with a $910,000 gain exclusion for 2026.21Internal Revenue Service. Expatriation Tax This exit tax is one of the most aggressive departure provisions in any developed country, and it catches people who don’t plan ahead.
If you want certainty before you go, Canada lets you ask the CRA to formally assess your residency status by filing Form NR73 (leaving Canada) or Form NR74 (entering Canada). The CRA will review your ties and issue a determination, though it isn’t binding. The UK’s SRT is designed for self-assessment and generally doesn’t need an HMRC ruling, but complex cases (split-year treatment, for example) often benefit from professional advice. The US has no equivalent formal determination process for departing residents, only the sailing permit requirement and the obligation to file a final or dual-status tax return.19Canada Revenue Agency.
