Track your tax day thresholds, visa expiries, and travel documents in one place. Built for expats, digital nomads, and frequent flyers who can't afford to get it wrong.
Four modules that work together so you always know where you stand, legally.
Track days spent in each country against residency thresholds — Singapore's 183-day rule, Schengen's rolling 90/180, UAE, UK, US FEIE and more. Ongoing trips update automatically every day.
See every visa and permit expiry at a glance. Get alerts 90, 30, and 7 days before anything expires — including the 6-month passport validity rule that airlines and border agents enforce.
Log your passport, visas, insurance certificates, flight bookings, and hotel confirmations. Everything searchable and organised, with expiry tracking. Upload scans directly in the full app.
At year end, get a clean report: days per country, tax residency status, visa usage, total travel stats. Hand it directly to your accountant or use it for your own tax filing.
When you scan a passport, BorderBook reads only the expiry date and nationality — the fields needed for compliance alerts. Your passport number, date of birth, and the photo itself are never uploaded, never stored, never seen by us. OCR scanning happens entirely in your browser. Your trips and visa dates are stored securely on Google Firebase in your region (Asia Southeast 1). You can delete all your data at any time from the app.
No spreadsheets. No calendar reminders that fire too late. Just open BorderBook.
One click. No new password to forget. Your data syncs across all your devices automatically.
Pick from presets or add custom countries. Log your visas, passport expiry, and key documents in under 5 minutes.
Add an arrival date when you land. Leave departure blank if you're still there — the day count updates automatically. Set departure when you leave.
Working abroad on an employment pass? Track your residency days and keep your work visa status clear.
Hopping between countries? Never accidentally trigger tax residency somewhere you don't want to be.
Constant business travel adds up fast. Know exactly how many days you've spent in each jurisdiction.
Managing residency obligations in two countries at once? BorderBook keeps both in view simultaneously.
Free to use. No credit card. Your data is yours.
