Which country can tax you?
Track your days across countries and find the treaty article that decides the answer — before your accountant has to.
The residency question, made countable
Residency tests are day counts and ties: how many days you spent in a country, where your home and family are, where your work happens. Most guides leave you to tally this by hand across scattered pages.
- A running day count per country, from the trips you enter.
- The test that applies to your situation, explained in plain language.
- The double-tax treaty article that decides the tie when two countries both claim you.
- Every rule carries its official source and the date it applies from.
Who it is for
Remote workers, digital nomads, people with income from more than one country, and anyone who has asked "am I about to become resident somewhere I did not intend to be?"
Not advice, an orientation
This is a way to see the shape of your position and the questions to bring to a professional — not a substitute for one. Treaty texts and thresholds are cited, dated and never invented.
