Tax Day Tracker

Tax Day Tracker — Days & Earnings for a Life Worked Abroad

Earn in one country, taxed in another? Then you know the days decide everything. Cross the wrong line and it costs you.

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.

COUNTS THE DAYS THAT MATTER
183-day rule, consecutive streaks, days out of country, departure and arrival days handled right. See exactly where you stand.

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 any trip into a clean PDF. Bill as yourself or your company, straight from your records.

KEEPS YOUR PROOF
Attach passport entry and exit stamps to each 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, one tap, 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.
