Tax Day Tracker — Days & Earnings for a Life Worked Abroad
Earn in one country, taxed in another? Then you already know: the days decide everything. Cross the wrong line and it costs you. Miss a record and you're guessing at year-end.
I built this because I live it — offshore, chasing the 183-day rule with a spreadsheet that couldn't keep up.
It's for anyone who works across borders: divers, seafarers, oil & gas and mining crews, air crew, consultants, contractors, remote workers — anyone counting days away from their tax home.
What it does:
Counts the days that matter — 183-day rule, consecutive streaks, days out of country, departure and arrival days handled right.
Tracks what you earn — day rates, salary, travel, saturation and skill bonuses, allowances. Any currency, live rates. By month, trip, or custom dates.
Invoices in seconds — turn a trip into a clean PDF. Bill as yourself or your company.
Keeps your proof — attach passport entry and exit stamps to every trip. Stored on your device.
Plans ahead — see what your next rotation does to your day count before you commit.
Exports to Excel — the whole picture, ready for your accountant.
No accounts. No ads. Your data stays on your phone. Free for 14 days.
Built by an offshore worker who got tired of losing track. If your work crosses borders, this is the tool I wish I'd had years ago.
Not tax advice. Always check with a qualified tax professional.
