What is Tax Residency?
Tax residency determines which country can tax your income. Most countries use a physical presence test — spend too many days there, and you may owe taxes on your worldwide income. Our free tracker helps you stay informed and avoid unexpected tax obligations.

When the Days Add Up in More Than One Country
residex.io tracks your presence across every country and warns you before you cross a residency threshold. But the moment your days trigger residency in two places at once, the question stops being how many days and becomes which country actually gets to tax you — a matter of treaty tie-breakers, dual-residency rules, and reporting obligations.
That’s where Amanda picks up. Amanda turns your travel reality into a clear map of your real cross-border obligations, so overlapping residency doesn’t turn into an unexpected tax bill in two jurisdictions.

Understanding Tax Residency
Tax residency is a critical concept for anyone who travels internationally or lives abroad. Unlike citizenship, tax residency is typically determined by where you physically spend your time. Each country has its own rules, but most follow the 183-day rule as a primary test.
Being tax resident in a country usually means you must declare and pay taxes on your worldwide income there. This can lead to complex situations for digital nomads, expats, and frequent travelers who may trigger residency in multiple jurisdictions simultaneously.
How Our Residency Tracker Helps
Our free residency tracker monitors your days spent in each country and alerts you when you’re approaching key thresholds. Unlike spreadsheets, it automatically calculates rolling periods, handles date ranges, and gives you a visual overview of your travel patterns.
All data is stored locally on your device using browser storage. We don’t require accounts, don’t collect personal information, and your travel data never touches our servers. This makes residex.io the most private way to track your tax residency risk.
