Tax-residency calculators
Day tests are one part of residency. Each page explains the other factors and official sources.
Before you count
A few questions about day rules, your data and what the results mean.
How many days can I stay in a country without becoming a tax resident?
For many countries the headline figure is 183 days in a year, but the details differ: the US uses a weighted 3-year formula, Australia counts July–June, and several countries also look at your home, family or economic ties regardless of day count. Each country page explains the exact rule.
Do the day I arrive and the day I leave count?
It depends on the country: the US counts any day with any presence, while UK-style end-of-day counting effectively counts nights. This calculator applies each country’s own convention to the same ledger — that is the point of entering your trips once.
Is my travel data sent anywhere?
Ordinary calculator inputs are processed in your browser and saved in local storage, with no account required. If you use Share link, the URL contains your trips: recipients can read them, and opening the link sends the URL to our host. Hosting and Cloudflare Web Analytics also process technical visit data. See the privacy page for details.
Is this also a Schengen 90/180 calculator?
Yes — the same ledger also runs the Schengen stay rule (90 days in any rolling 180-day window, all 29 states pooled, both entry and exit dates count) on its own page: the Schengen 90/180 calculator. The stay rule and tax residency are different tests that the same trip ledger feeds.
Is this tax advice?
No. This is an informational tool that replays published day-counting tests. Real residency can depend on facts a calculator cannot see (housing, family, treaties, visa categories). Verify with a qualified cross-border tax adviser.
