Tax Residency Genius

Track every day abroad across 45 countries. Know if you've crossed the 183-day line before the taxman does. Free, private, on-device — no account needed.

Counting days in your head? Stop.

Tax Residency Genius tracks every day you spend in every country and tells you — instantly — whether you've crossed the 183-day tax residency line. Built for digital nomads, expats, remote workers, and anyone who lives life across borders.

45 COUNTRIES, ONE APP Australia, USA, UK, Canada, New Zealand, Singapore, UAE, Germany, Japan, Thailand, Portugal, Ireland, Italy, Spain, France, Switzerland, Netherlands, Greece, Croatia, Poland, Cyprus, Malta, Costa Rica, Paraguay and more — each with its own day-count rule and fiscal year.

TRACK TRIPS THE EASY WAY Tap a country, drop in your travel dates, hit calculate. Done. Add multiple trips, edit anything, switch fiscal years on the fly. Works for past years, the current year, and trips you haven't taken yet.

INSTANT RESIDENCY VERDICT See whether you're "Likely Tax Resident" or "Likely Non-Resident" the second you tap calculate. Visual progress bar shows exactly how close you are to the threshold — and the app warns you when you're within 14 days of crossing.

FISCAL YEAR AWARE Most apps assume January to December. Real life doesn't. Tax Residency Genius understands Australia's July–June year, the UK's April 6 start, India's April–March year, South Africa's March–February year, and standard calendar-year countries. No more mental math.

PLAN YOUR NEXT TRIP Add a future travel period and watch your day count update. Find out if that two-month stay in Lisbon or three-week stint in Bali will tip you over before you book the flight. Plan with confidence, not anxiety.

100% PRIVATE — DATA STAYS ON YOUR PHONE No accounts. No login. No cloud. No tracking. Your travel history lives on your device and nowhere else. Delete the app, delete the data — that simple.

BUILT FOR THE GLOBALLY MOBILE Whether you're a digital nomad chasing summer, an expat juggling two countries, a retiree splitting time between homes, a contractor working remotely abroad, a crypto investor optimising tax residency, or a dual citizen managing two passports — this app gives you the clarity you need to stay on the right side of every tax authority.

WHY 183 DAYS MATTERS Most countries use a "day count" test as the simplest way to determine tax residency. Cross the threshold (usually 183 days, but sometimes 120, 180, or 182) and you may owe tax there — even if you didn't intend to become a resident. Tax Residency Genius takes the guesswork out of it.

This app is a planning tool, not legal or tax advice. Always consult a qualified tax professional before making decisions based on residency status.
