Methodology

Where each rule comes from

We are not tax advisers. So we do not offer opinions: we read each country's law, cite it, and say how much confidence what we understood deserves.

The three confidence levels

High · 36 rules

36

The law states a number of days and a window, and we have read it.

Medium · 17 rules

17

The number is firm but some detail is not, almost always how the days of arrival and departure are counted.

Low · 10 rules

10

The country has no day count in its law and the number is an approximation of ours: Austria, Belgium, Germany, Finland, Liechtenstein, Luxembourg, Malta, Netherlands, Sweden, San Marino. Here the counter warns; it never rules.

How a rule gets written

Each of the 63 rules lives in the app's code with its source cited, and this site is generated from there by a tool. One version of the truth, so the app and the site cannot say different things.

  1. 01Find the country's law, not an article summarising it.
  2. 02Note the threshold, the window, and how it counts the days of arrival and departure. If the law is silent, say that it is silent.
  3. 03Mark whether it is a tax residency test or a stay limit, like Schengen, which is not the same thing.
  4. 04Write down what else that country looks at besides days. An automated test checks that no tax rule is published without that warning.
  5. 05Date the review and note when it is due to be looked at again.
