Basis

TUIR Art. 2 (2024 reform)

Since the 2024 reform, being physically present in Italy for more than 183 days in a calendar year makes you an Italian tax resident on its own — and fractions of a day count toward that total. Staying at 183 days or fewer avoids this particular test, but Italy applies several independent tests, so it does not by itself guarantee non-residency. Residency here means Italy can tax your worldwide income.

Who it applies to

This matters most if you are:

• A remote worker, digital nomad, or frequent traveler spending long stretches in Italy.
• Someone whose home, spouse, or children remain in Italy while you live or work abroad.
• An expat moving to or from Italy mid-year, where the day count sits close to the threshold.
• Anyone still enrolled in the Italian resident population register (anagrafe) after leaving.

It applies to individuals regardless of nationality — residency here is about presence, personal ties, and registration, not citizenship or visa status.

The rule — and why it exists

Under the reformed Article 2 of the TUIR (rewritten by D.Lgs. 209/2023, effective 1 January 2024), you are an Italian tax resident if, for the greater part of the tax year, any one of these applies:

• Physical presence. More than 183 days in Italy in the calendar year, fractions of a day included. This is now an autonomous test.
• Residenza. Your habitual abode — where you actually and habitually live — is in Italy under the Civil Code.
• Domicilio. Italy is the main centre of your personal and family relationships. Since 2024 the emphasis is on personal and family ties, not primarily business interests.
• Anagrafe registration. Enrolment in the resident population register for most of the year, which now acts as a rebuttable presumption of residency.

Why it exists: countries use presence, a habitual home, and family ties as proxies for where your economic and personal life really sits. The multi-pronged test stops people avoiding residency purely by counting days while still keeping their real base and family in Italy.

Counting the days

1. 1Add up every day you are physically present in Italy during the calendar year (1 January to 31 December).
2. 2Fractions of a day count as a full day — an arrival day, a departure day, or a few hours in the country all add to the total.
3. 3The count resets at the start of each new calendar year; it is not a rolling 12-month window.
4. 4More than 183 days of presence is an autonomous residency test, independent of your home, family, or anagrafe registration.

The 2024 change is significant. Before then the day count worked mainly through registration and centre-of-interests concepts. Now physical presence over 183 days — counting part-days — is enough by itself to make you resident, as confirmed by the Agenzia delle Entrate in Circolare 20/E of 4 November 2024.

Examples

Example 1 — resident by days

You spend 200 days in Italy across a calendar year, arriving and leaving on various dates. Part-days count, so you comfortably exceed 183 days. That alone makes you an Italian tax resident, and Italy can tax your worldwide income for that year — regardless of where your home or family is.

Example 2 — resident despite few days

You spend only ~120 days in Italy, but your spouse and children live in Rome and your family life is centred there. Your domicilio is in Italy, so you are resident under Article 2 even though you never crossed the 183-day line.

Example 3 — still on the register

You moved abroad but never cancelled your anagrafe registration and stayed enrolled for most of the year. That registration creates a rebuttable presumption of Italian residency, which you would have to actively disprove.

Exceptions & edge cases

• Double-taxation treaties. If you are resident in two countries, the relevant treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) assigns a single treaty residence and divides taxing rights.
• Anagrafe is rebuttable. Registration is now a presumption, not conclusive — you can rebut it with evidence that your real life was genuinely abroad, though the burden falls on you.
• "Greater part of the year." Each test is assessed over the greater part of the tax year, so residency turns on the majority of the year, not a single moment in time.
• Special regimes. Italy offers optional regimes (such as impatriate and flat-tax schemes) that change how a resident's income is taxed — they affect the tax outcome, not whether you are resident.

Common misconceptions

• "Under 183 days means I'm safe." False — domicilio, habitual abode, or anagrafe registration can each make you resident with any number of days.
• "Arrival and departure days don't count." They do — fractions of a day count as full days since 2024.
• "Only Italian income is taxed." Residency puts your worldwide income in scope, subject to any applicable treaty.
• "It's a rolling 12-month count." No — the day count is measured within the calendar year and resets each 1 January.
