Digital nomad tax residency, explained

The nomad folklore says: keep under 183 days and you're safe. The folklore is wrong in four specific, checkable ways. Here is how the actual rules treat location-independent people — and a workflow that keeps you honest.

Myth 1: "183 days everywhere"

The thresholds differ: Malaysia 182, Thailand and the Philippines 180, the UAE effectively 90, Ireland 280 over two years, the US a weighted three-year formula, the UK a three-layer test with a 6 April window. Even the shared figure means different things — indicator in France, presumption in Spain, day layer in the UK. The comparison table is the reference.

Myth 2: "Under the threshold, I'm nobody's resident"

Day tests are floors for people with no other ties. A kept home, a partner, children in school, a company you manage, an economic centre — any of these can make you resident at 40 days a year. The systems explicitly weigh lives, not itineraries: France's foyer, the UK's sufficient ties, Spain's economic-interests trigger, Germany's Wohnsitz. This is why this site pairs day counts with a "what this does not decide" checklist on every country.

Myth 3: "The US formula is just 183 days"

The Substantial Presence Test reaches back two years: current days + ⅓ of last year + ⅙ of the year before. Three 120-day US years = 180 weighted days — one day under, with the flip on the next day. Nomads who "only visit" the US are exactly the people the weighting catches. See the formula explained and run your own years in the US calculator.

Myth 4: "Schengen days are tax days"

The Schengen 90/180 rule is a border-stay rule — pooled across 29 states, rolling 180-day windows, entry-day counting. It decides nothing about tax. The same trips feed both tests, which is why the ledger approach works: one input, both answers. See the Schengen calculator.

A ledger-first workflow

1. Record trips as dated stays (not memories) — paste a whole list at once, or import your CSV. Everything computes in your browser.
2. Watch the non-183 outliers — 180/182 thresholds, the US weighting, the UK tax-year window, Switzerland's nights.
3. Watch the reverse direction — how many safe days remain this year given what you did last year (the US answer changes with every prior-year day).
4. Keep the evidence — export the ledger as CSV and the verdict summary; if a threshold is near, engage an adviser before crossing, not after.
