residex.ioEvery trip accounted forItaly’s 183-Day Rule
The greater part of the year — and since 2024, physical presence counts on its own
Four ways to be resident, each for the greater part of the year
Italy asks whether, for the greater part of the tax year — more than 183 days, or more than 184 in a leap year — any one of four things was true: you were registered in the municipal population register (the Anagrafe), you had your residence in Italy, you had your domicile there, or you were physically present.
Physical presence is the newest of the four. Before 2024 a person who was simply in Italy a lot, without registering or establishing a home, could argue they fell outside the test. That argument is gone: since the 2024 reform, days in Italy count in their own right, and fractions of days count as days.
Registration is not a formality
Being on the Anagrafe for more than half the year used to be an absolute presumption of residence. It is now rebuttable — you can show you actually lived elsewhere — but the starting point still favours the register, and someone who moves abroad without deregistering, or without enrolling in the register of Italians abroad (AIRE), often finds Italy still treats them as resident.
Domicile means relationships now, not business
The same reform redefined domicile as the place where your personal and family relationships mainly develop, rather than the centre of your business and interests. So a person whose partner and social life are in Italy may be domiciled there even if their work and income are not.
None of that is a day count, and none of it is something residex.io can see.
What residex.io does about it
Residex counts your days in Italy over the calendar year, including the day you arrive and the day you leave, warns as you approach 183, and can notify you on the date a planned trip would take you over. If you hold Italian citizenship and say so in Settings, it keeps counting — a passport does not stop you becoming resident by presence.
Who needs to watch this
- Italians abroad who never deregistered
- Remote workers on Italy’s digital nomad visa
- People whose partner or family lives in Italy
- Anyone who assumed presence alone did not count
Counting days is where this stops
Residex tells you exactly where you stand against this threshold and warns you before you cross it. Crossing it is not a conclusion, though: it does not tell you what you owe, whether a treaty offers relief, which forms to file, or how this interacts with residency you already hold elsewhere.
That is where Amanda picks up — turning a day count into a read on your real cross-border obligations.

How residex.io works
residex.io tracks where you have physically been, and tells you where that puts you against each country's own residency threshold.
What it does: • Counts your days per country, and per area for the Schengen 90/180 rule • Applies each country's actual rule — 183 days for most, 180 for Thailand, the UK's 6 April tax year, Portugal's rolling twelve months, and the US weighted three-year test • Counts days the way each rule counts them, including the arrival and departure days that most tests count and a nights-based tally misses • Warns as you approach a threshold, and can notify you on the date a trip you have already planned would take you across it • Exports to CSV, or hands off to Amanda for the compliance picture
Built for digital nomads, frequent travellers, expats, and anyone whose year is split across borders.
On your device, and nowhere else. There is no account, no login, and no copy of your travel history on our servers — residex works offline because the data never needed to be anywhere else.
It leaves your device only when you decide to send it: • A backup file you save yourself • A transfer to another device, encrypted with a code only you hold — the server relaying it cannot read what it is carrying • A hand-off to Amanda, which you start
We do receive a small amount of anonymous usage information — how many trips are in a log, how old an install is, the language the app is used in, and a random identifier that is not linked to you. Never a trip, a date, a destination, or your name. It is listed in full in our Privacy Policy.
The trade-off worth knowing: because your device holds the only copy, clearing your browser data or deleting the app erases it, and we cannot restore it. Save a backup before you switch devices.
No — residex is a day counter, not a compliance engine. It flags when you cross a threshold like the 183-day rule, but turning that into specific filings, tax exposure, or reporting obligations depends on your jurisdictions and personal ties.
For that, our partner Amanda maps your full cross-border legal exposure across countries, surfaces the filings and deadlines you trigger, and turns the data residex collects into a concrete compliance picture you can hand to your accountant.
You can export your residex trips and import them straight into Amanda — the CSV formats are aligned.
