What's at stake

183 nights decide your country.
Nobody counts them in time.

Tax residence plays out night by night, across the whole year — holidays included. The hard part isn't counting in December: it's keeping track all year, with the paperwork to back it up. Sojourn makes that part effortless.

How it works

Set it up once. Forget it.

1

Your nights count themselves

Every night, Sojourn quietly notes the country where you slept. Zero input, zero reminders to tick off — open the app to a year already up to date.

2

Your proofs file themselves

Train ticket, hotel booking, receipt — drop it in as you go, two taps. Everything lands on the right day, dated and in one place.

3

One tap, one report

Whenever you need it: a clean, dated report of your year, ready to hand to your accountant or the tax office.

Everything in one place

No spreadsheet. No shoebox of receipts.

🌙

Automatic night count

Every night logs itself to the right country — holidays included. Your year is always up to date.

📈

See where you're heading

Sojourn projects your pace to 31 December, so you see the whole year — not just today.

📏

The 183 line, visualized

Legal limit and safety target on a single gauge. Your remaining margin, at a glance.

🗂️

Proofs, centralized

Tickets, bookings, receipts — filed to the right day as you go. No more end-of-year archaeology.

📄

Turnkey report

A clean, dated summary of your nights and proofs — export it whenever someone asks.

💼

Workdays too

Keep the split of your worked days, country by country — handy for payroll and filings.
