Understanding Day Count Rules
Non-EU passport holders may stay up to 90 days in any rolling 180-day window across all 27 Schengen countries. Both entry and exit days count. The window slides daily.
Most countries treat you as a tax resident if you spend 183+ days in a calendar year. Some countries have additional triggers like property ownership or economic ties.
Weighted 3-year formula: current year days + 1/3 prior year + 1/6 two years prior. If total reaches 183+, you may be a US tax resident (US citizens are always residents).
Many countries have specific tourist visa durations: Mexico 180 days, Thailand 60/90 days, UK 180 days, etc. Set custom limits to track these alongside tax thresholds.
Disclaimer: This tool provides day counting estimates for informational purposes only. Tax residency and visa compliance involve many factors beyond physical presence. Always consult a qualified tax professional or immigration attorney for advice specific to your situation. Report an issue.
Frequently Asked Questions
How does the Schengen 90/180 rolling window work?
The Schengen 90/180 rule allows non-EU citizens up to 90 days within any rolling 180-day period in the Schengen Area. The window slides forward each day, so it is not a fixed calendar period. Both entry and exit days count as full days. When you leave, the days start "expiring" from the window after 180 days, gradually restoring your allowance.
What is the 183-day tax residency rule?
Most countries use a 183-day rule to determine tax residency: if you spend 183 or more days in a country during a calendar year, you are generally considered a tax resident and may owe taxes on worldwide income. Some countries count partial days or use fiscal years instead of calendar years. This tool tracks calendar-year days per country.
How does the US Substantial Presence Test work?
The US Substantial Presence Test counts: all days present in the US during the current year, plus one-third of days in the prior year, plus one-sixth of days two years prior. If this weighted total reaches 183 or more, you may be treated as a US tax resident. US citizens are always tax residents regardless of days spent abroad.
Can I set custom day limits for specific countries?
Yes. The Day Tracker lets you set custom thresholds for any country, such as Thailand 180-day tourist limit, Mexico 180-day FMM limit, or any other visa restriction. The dashboard will monitor these thresholds alongside the standard Schengen and tax residency calculations.
