Tax residency rules by country

How many days before a country treats you as a tax resident? The day count — often around 183 days — is the part you can actually calculate, and it’s what Yuravia tracks. But it is rarely the only test: a home, your family or your economic ties can make you resident too, and a few countries have no day rule at all. Pick a country for its real tests, threshold and official source.

How tax residency actually works

Most countries tax their residents on worldwide income, so one question decides a large part of your tax bill: which country counts you as resident? Almost every country answers it with more than one test, and you only have to meet one of them. We split those tests into the part a tracker can compute and the part it can’t.

The day count is the part we can calculate

The famous “183-day rule” is really a family of day-count tests: 183 days in some countries, 180 or 182 in others, a rolling 12-month window elsewhere, and the US Substantial Presence Test, which weights three years at once. The number and the window change from country to country — which is exactly why a single “half the year” heuristic gets people caught. This is the one test we track for you, and every country page shows the exact threshold and window.

The tests a day count can’t see

Staying under the threshold is necessary, not sufficient. A permanent home available to you, your family’s location, the centre of your economic or vital interests, your domicile, even your nationality or immigration status can each make you resident on far fewer days — and a few countries (France, the Netherlands, Belgium, Mexico) have no statutory day count at all. We list these “other ways” on every country page and say plainly that no day-counter can measure them.

Why every page cites an official source

Tax rules change and bad summaries spread, so we build each page from the national tax authority or the statute itself, name that source, and stamp the date a human last checked it. When official and secondary sources disagree, the official text wins. See how we research and review these rules.

Frequently asked questions

How many days make you a tax resident?

Most countries treat you as a tax resident once you spend 183 days or more there in a tax year — but it is not universal. Some use 180 or 182 days, a rolling 12-month window, a multi-year combined test, or a weighted lookback like the US Substantial Presence Test. Each country page here shows the exact threshold and the official source.

Is the day count the only thing that matters?

No. Day count is a proxy. Countries can also claim you through a permanent home, your family, or your centre of vital interests, often on far fewer days. Staying under a threshold is necessary but not sufficient — and two countries can claim you at once.

How accurate are these thresholds?

Each rule is summarised from the country’s own tax authority and carries the date it was last checked. Thresholds and tests do change, so we link the primary source on every page and recommend confirming before you rely on it.

Can two countries treat me as a tax resident at the same time?

Yes. Each country sets its residency tests independently, so being resident in two at once is common. When it happens, a double-tax treaty usually has a tie-breaker — permanent home, then centre of vital interests, then habitual abode, then nationality — that assigns you to one. We track your days everywhere precisely because more than one country can claim you.

Do the free calculators track the non-day tests too?

No. The calculators and alerts handle the day count — the part we can compute from your trips. The home, family, economic-centre and domicile tests can’t be measured by counting days, so we document them on each country page rather than pretend to track them. Treat the day count as your early-warning line, not a clean bill of health.

Not tax advice. These pages summarise each country’s day-count rule from its tax authority as a starting point. Real residency depends on far more, and thresholds change. Always confirm with the official source or a qualified adviser.
