Your travel ledger

Paste your travel list (one stay per line)

Format: YYYY-MM-DD ~ YYYY-MM-DD XX with the two-letter code of a country on this site, or a single day YYYY-MM-DD XX.

How it works

1

Build your ledger

Add stays one by one, or paste a list. Overlapping trips are merged and cross-year trips split automatically.

2

One pass, all countries

The same ledger is evaluated under each country's own counting convention — any-part days for the US, income years for Australia, statutory 183-day rules elsewhere.

3

See the math, not just the answer

Every verdict expands into the exact computation, cites the official publication it follows, and shows your remaining safe days.

Country calculators

Each page pairs the calculator with a plain-language explainer of that country's rule, official sources and a verification date.

United States Substantial Presence Test: at least 31 days in the current year AND a 3-year weighted total (all days + ⅓ of last year + ⅙ of the year before) of at least 183 days. United Kingdom Statutory Residence Test in three layers: automatic overseas tests (fewer than 46 days for arrivals), automatic UK tests (183+ days), and a sufficient ties test in between. France 183-day rule as an indicator of principal stay, alongside four other statutory criteria: household (foyer), principal residence, professional activity, or centre of economic interests. Spain Statutory 183-day presumption with sporadic absences counted as presence, plus permanent-home and economic-interest criteria. Italy 183-day presence as an indicator, alongside population-registry registration, civil-code domicile and residence. Singapore 183-day statutory rule, with a 3-consecutive-year rule and a 60-day short-term employment concession on the side. Australia 183-day test over the July–June income year, one of four tests (resides, domicile, 183-day, superannuation) — the "resides" test is the primary one. Ireland 183 days in the calendar year, or 280 days combined over this and the previous year with at least 30 days in each — the two-year test catches repeated medium stays. Switzerland 90-night threshold for presumed cantonal residence, nights counted; federal residency is abode-based and can apply even below the threshold. United Arab Emirates Resident at 183 days of presence; possibly resident from 90 days if you also have a permanent home or place of business in the UAE. Malaysia 182-day statutory rule — deliberately not 183 — with linked-stay rules that can make short stays count across years. Thailand 180-day rule — another "not 183" country — with the remittance rule taxing residents on foreign income brought into Thailand. Philippines 180-day rule for resident-alien classification; resident aliens are taxed on Philippine-source income.

Frequently asked questions

How many days can I stay in a country without becoming a tax resident?

For many countries the headline figure is 183 days in a year, but the details differ: the US uses a weighted 3-year formula, Australia counts July–June, and several countries also look at your home, family or economic ties regardless of day count. Each country page explains the exact rule.

Do the day I arrive and the day I leave count?

It depends on the country: the US counts any day with any presence, while UK-style end-of-day counting effectively counts nights. This calculator applies each country’s own convention to the same ledger — that is the point of entering your trips once.

Is my travel data sent anywhere?

No. All calculation happens in your browser, and your ledger is saved only in your device’s local storage. There is no account, no upload and no tracking of your trips.

Is this tax advice?

No. This is an informational tool that replays published day-counting tests. Real residency can depend on facts a calculator cannot see (housing, family, treaties, visa categories). Verify with a qualified cross-border tax adviser.

Informational only — not tax advice. Day-counting tests are one part of tax residency; housing, family, employment and treaty factors can change the outcome. See the full disclaimer.
