Common misconceptions
“A count below the day threshold settles tax residence.”
A recorded-day total is one component. Review the separate conditions and exceptions described on this page.
“The window follows the latest twelve months.”
This counter uses the calendar year. A rolling window and a calendar year can produce different totals.
