How the days are counted

More than 183 days, consecutive or not, in the tax period, which since 2020 is the calendar year. The regulation says expressly that the day of entry and the day of exit count. Sporadic absences of 30 consecutive calendar days or fewer are counted as if you had been inside; longer ones are not.

The count does not decide on its own, either your residency or what you end up paying.
