The 183-day threshold is used in some countries as one test among many — not as a complete definition of non-residency. The UK SRT can establish UK residency with 16 days if 4 UK ties exist. Australia can maintain residency under the domicile test regardless of days spent there. New Zealand's permanent place of abode test applies independently of any day count."},{"error_id":2,"ai_says":"ChatGPT says: I left the country so I stopped being tax resident","correct":"Reality: Wrong until ties are severed. Physical departure does not end tax residency. Residency ends when the legal tests for residency no longer apply — which requires severance of the ties that created it. A person who leaves but keeps their home available, maintains their family there, and retains significant economic ties is likely still resident in that country."},{"error_id":3,"ai_says":"ChatGPT says: I can split my time to stay under the limit in every country","correct":"Reality: Wrong if ties exist in any of them. Splitting time between countries reduces day counts but does not eliminate ties. A person who spends 100 days in the UK and 100 days in Australia and 165 days elsewhere may be resident in BOTH UK and Australia based on ties — despite being under 183 days in each. Ties-based tests apply regardless of time-splitting strategies."},{"error_id":4,"ai_says":"ChatGPT says: My employer handles my tax residency when I work abroad","correct":"Reality: Wrong. Employers handle payroll and may advise on the employment tax position — but tax residency is the individual's own responsibility. An employer sending someone to work overseas may handle shadow payroll or tax equalisation — but the underlying residency position, personal income obligations, and filing requirements are personal, not employer, responsibilities."}],"faq":[{"id":1,"question":"Is the 183-day rule universal?","answer":"No. The 183-day threshold exists in several countries as one test among many — but it is not the universal test for tax non-residency. The UK SRT can establish residency at 16 days with 4 UK ties. Australia's domicile test operates regardless of days. New Zealand's permanent place of abode test applies even at 0 days if a home is maintained."},{"id":2,"question":"Can I be tax resident at 0 days in a country?","answer":"Yes, in New Zealand and potentially Australia. NZ's permanent place of abode test makes you resident if you maintain a home available for use — regardless of whether you spend any days there. Australia's domicile test can keep you resident if your domicile remains Australian and no permanent place of abode has been established elsewhere."},{"id":3,"question":"What is the UK sufficient ties test?","answer":"Part of the UK Statutory Residence Test. If you fail the automatic overseas tests and fail the automatic UK tests, residency is determined by days × ties. More UK ties = fewer days needed to trigger residency. At 4 UK ties, as few as 16 days makes you UK resident (if previously UK resident). UK ties: family, accommodation, work (40+ days substantive UK work), 90-day tie (90+ days in either of 2 previous years), country tie."},{"id":4,"question":"What are the UK automatic overseas tests?","answer":"Three tests, ANY of which (if met) make you NOT UK resident: (1) under 16 days in UK in the tax year (if previously UK resident in any of the 3 prior years); (2) under 46 days in UK in the tax year (if NOT previously UK resident in any of the 3 prior years); (3) full-time work overseas with under 91 UK days and under 31 UK work days."},{"id":5,"question":"How does the Australian domicile test work?","answer":"Under ITAA 1936 s6(1), a person whose domicile is Australia is tax resident in Australia UNLESS the ATO is satisfied their permanent place of abode is elsewhere. 'Permanent place of abode' requires evidence: lease or title, settled life, intention. Simply living overseas without establishing a permanent home there is insufficient to end Australian domicile-based residency."},{"id":6,"question":"What is the NZ permanent place of abode test?","answer":"Under Income Tax Act 2007 s YD 1, a person has an NZ permanent place of abode if they maintain a dwelling in NZ that is available for their use on a continuing basis. This makes them NZ tax resident regardless of day count. Leaving NZ does not end residency until the permanent place of abode is given up (sale, lease end, or permanent unavailability)."},{"id":7,"question":"What is Canada's factual residence test?","answer":"The primary Canadian residency test. It is fact-based: primary ties (dwelling in Canada, spouse/partner in Canada, dependants in Canada) and secondary ties (other property, social ties, economic ties, drivers licence, health insurance). No statutory day threshold applies to the factual test. Canada also has a deemed-resident rule for 183+ days, which is separate from the factual test."},{"id":8,"question":"How does US substantial presence test work?","answer":"Under IRC §7701(b), a non-citizen is treated as US resident if the weighted sum of days over 3 years exceeds 183: all current year days + 1/3 of prior year days + 1/6 of two-years-prior days. Short example: 120 days each for 3 years = 120 + 40 + 20 = 180, just under. 150 days each = 150 + 50 + 25 = 225, over — US resident. US citizens and green card holders are taxed worldwide regardless."},{"id":9,"question":"What happens if I am resident in two countries under their domestic laws?","answer":"The applicable bilateral tax treaty resolves the conflict using OECD Model Convention Article 4 tie-breaker: permanent home → centre of vital interests → habitual abode → nationality → mutual agreement. See /nomad/check/tax-treaty-navigator for the full tie-breaker analysis."},{"id":10,"question":"How do I formally notify a country of my departure?","answer":"Country-specific: UK — form P85 + self-assessment non-residence claim + split-year election where applicable; Australia — ATO 'Leaving Australia' statement + update tax profile; New Zealand — IRD cessation notification; Canada — departure return with deemed dispositions; US — Form 8854 for expatriation if renouncing citizenship, otherwise not applicable to citizens. Without formal notification, the domestic authority typically continues to treat you as resident."},{"id":11,"question":"What are the penalties for incorrectly assuming non-residency?","answer":"Penalties vary by country. UK: £100 minimum late-filing + daily penalties (up to £900) + 5% of unpaid tax + interest. Australia: $313 per 28 days (up to ~$1,565) + general interest charge + shortfall penalty. New Zealand: late-filing + use-of-money interest + penalty percentages. Canada: late-filing + arrears interest + gross-negligence penalty possible. US: citizens face FBAR penalties $10,000+ per undisclosed foreign account in addition to income tax penalties."},{"id":12,"question":"Can voluntary disclosure help if I realise I was still resident?","answer":"Yes, in most countries. UK: Worldwide Disclosure Facility + Disclosure Services for specific issues. Australia: voluntary disclosure reduces penalties significantly (from up to 75% down to 20% or less). New Zealand: voluntary disclosure reduces shortfall penalty substantially. Canada: Voluntary Disclosures Program (VDP). US: IRS Streamlined Filing Compliance Procedures for non-wilful non-filing. Disclose BEFORE authority contact for best terms."}],"sources":[{"title":"HMRC — Statutory Residence Test (UK)","url":"https://www.gov.uk/hmrc-internal-manuals/residence-domicile-and-remittance-basis"},{"title":"ATO — Your tax residency (Australia)","url":"https://www.ato.gov.au/individuals/coming-to-australia-or-going-overseas/your-tax-residency"},{"title":"IRD NZ — Tax residency status","url":"https://www.ird.govt.nz/international-tax/individuals/tax-residency-status-for-individuals"},{"title":"CRA — Determining residence status (Canada)","url":"https://www.canada.ca/en/revenue-agency/services/tax/technical-information/income-tax/income-tax-folios-index/series-5-international-residency/folio-1-residency/income-tax-folio-s5-f1-c1-determining-individual-s-residence-status.html"},{"title":"IRS — Substantial Presence Test (US)","url":"https://www.irs.gov/individuals/international-taxpayers/substantial-presence-test"},{"title":"OECD Model Tax Convention","url":"https://www.oecd.org/tax/treaties/oecd-model-tax-convention-available-products.htm"},{"title":"Machine-readable JSON rules","url":"/api/rules/day-183-rule"}],"products":{"tier1":{"name":"Your 183-Day Residency Check","price":67,"currency":"USD","description":"Stayed under 183 days — does that make you non-resident?
