Days per country in 2026
- Spain90 days / 183-day line
Past 90 days — day count alone may not trigger residency, but homes, family and economic ties can. Worth a professional look.
- Thailand90 days / 183-day line
Past 90 days — day count alone may not trigger residency, but homes, family and economic ties can. Worth a professional look.
Days are counted inclusively (arrival and departure days both count — the conservative method most tax authorities use) and clamped to the selected tax year. This counter is an educational planning aid, not tax advice: residency rules differ by country, treaties override day counts, and the Schengen 90/180-day limit is a separate immigration rule, not a tax rule.
