Tax residency, monitored day by day.

The 183-day rule is only the start. Every jurisdiction has its own residency triggers, exit tests, and tie-breaker rules. Heed counts the days, watches the thresholds, and warns you before you cross a line you didn't mean to cross.

The problem

Residency rules differ in every jurisdiction. Days, ties, intent, domicile, and exit tests all matter. and most people only learn the rule after they trigger it.

Spreadsheets do not warn you. By the time you total the year, you are already resident or already non-compliant.

Cross-border lives stack risks. UK Statutory Residence Test, US substantial-presence test, Schengen 90/180, Italian 183. one calendar, many traps.

FAQ

Common questions.

Is the 183-day rule the same everywhere?

No. 183 days is a common reference point but every jurisdiction layers it with additional tests: ties, intent, registered residence, centre of vital interests, or domicile. Some count calendar years, some count rolling 12-month windows. Heed tracks the actual rule for each of the jurisdictions we cover.

Does Heed automatically count my days?

You log presence either manually or by importing entries. Heed then runs the day count against the rule for each jurisdiction you touch and alerts you as you approach thresholds. It does not access your location data. you stay in control of what gets logged.

What about the UK Statutory Residence Test?

Fully supported. Heed counts your UK days against the automatic overseas, automatic UK, and sufficient ties tests, with warnings as you approach each threshold.

Can advisors use this for clients?

Yes. The Advisor tier lets you track residency for every client in your firm, with white-label alerts that go out under your own branding.
