Tax residency decides which country can tax your worldwide income and where you must file. It is set by each country's own law, not by your passport or your residence card. The OECD notes that the right to reside somewhere, or holding citizenship there, does not by itself make you tax resident, and does not by itself end tax residency in the country you left.
Many people have heard that spending 183 days in a country makes you tax resident there. That is a common trigger, but it is only a starting point. Crossing 183 days usually creates residency, yet staying under it does not always keep you out, because most countries apply extra tests. Treat the day count as one factor, not the whole answer.
When the day count is unclear, authorities look at where your life is centred. They weigh where your home, family, work and main economic ties sit. Tax treaties use similar tie breaker rules to decide which country wins when two both claim you. This is why moving your days without moving your life often fails to change your residency.
When you become resident somewhere new, you may need to report all of your tax residences when opening bank accounts, because banks collect this under the Common Reporting Standard. Leaving your old country may also require formal steps to exit its tax net. Plan the exit and the entry together, and get advice for your exact facts before you rely on any single rule.
Not by itself. Tax residency is set by each country's law and usually turns on where you spend time and where your life is centred. Confirm with the relevant tax authority.
Yes, two countries can both claim you. Tax treaties contain tie breaker rules to decide which one prevails, but the outcome depends on your facts.
No. Many countries apply additional tests, so you can be tax resident even below 183 days. Check the specific rules for each country involved.
