What the rule actually says
The 183-day rule is widely cited as the test for tax non-residency. It is not. Most countries that use a 183-day threshold also have override provisions that can establish residency without reaching it — or remove residency even if it is exceeded. The United Kingdom's Statutory Residence Test can make a person UK resident with as few as 16 days if sufficient UK ties exist. Australia's domicile test can maintain Australian residency regardless of how many days are spent there. New Zealand's permanent place of abode test applies regardless of days. Canada's factual residence test is based primarily on ties, not a day threshold.
Leaving a country without formally severing ties is the most common mistake. A person who moves abroad but keeps their family home available, leaves their spouse in the home country, and maintains bank accounts and memberships there is likely still tax resident — even with zero days in that country. Tax residency is not ended by physical departure. It is ended by the legal severance of the factors that created it.
What most people get wrong
I stayed under 183 days so I am not tax resident — wrong as a universal rule. The 183-day threshold is used in some countries as one test among many — not as a complete definition of non-residency. The UK Statutory Residence Test 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.
I left the country so I stopped being tax resident — 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.
