- TUIR Art. 2 (2024 reform)
Since the 2024 reform, being physically present in Italy for the greater part of a calendar year — 183 days, or 184 in a leap year — makes you an Italian tax resident on its own, and fractions of a day count as whole days. Staying at 182 days or fewer (183 in a leap year) 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. Presence in Italy for the greater part of the calendar year — 183 days, or 184 in a leap 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
- 1Add up every day you are physically present in Italy during the calendar year (1 January to 31 December).
- 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.
- 3The count resets at the start of each new calendar year; it is not a rolling 12-month window.
- 4Reaching 183 days of presence (184 in a leap year) is an autonomous residency test, independent of your home, family, or anagrafe registration — so 182 is the last safe count in a normal year.
- 5Bounded's counter follows the leap-year rule: it flags day 183 in a normal year and day 184 in a leap year.
The 2024 change is significant. Before then there was no stand-alone presence test: the 183-day period measured how long you were registered in the anagrafe or had your domicile or residence in Italy. Now physical presence for the greater part of the year — 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. The circular gives the example of someone landing at 23:00 on 1 July 2024 and leaving at 01:00 on 31 December 2024: both days count in full, reaching 184 days and residency for that leap year. It also notes that merely temporary or occasional presence, such as a stopover for a connecting flight to another country, is taken into account to exclude residence.
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.
Frequently asked questions
No. The test is presence for the greater part of the tax year — 183 days, or 184 in a leap year — so 183 days in a normal year already makes you resident. Staying at 182 days or fewer (183 in a leap year) only avoids the physical-presence test. Your domicilio (centre of personal and family life), your habitual abode, or registration in the anagrafe can each make you resident regardless of your day count.
Per calendar year, from 1 January to 31 December. It is not a rolling window — the count resets to zero at the start of each new year.
Yes. Since the 2024 reform, fractions of a day count as a full day, so arrival days, departure days, and even a few hours in the country all add to the total.
Physical presence for the greater part of the year (183 days, or 184 in a leap year) is now an autonomous residency test on its own. Previously there was no stand-alone presence test: the 183-day period measured how long you were registered in the anagrafe or had your domicile or residence in Italy. Now presence alone, counting part-days, can make you resident.
It puts your worldwide income within the reach of Italian tax, not just Italian-source income. A double-taxation treaty may reassign taxing rights if you are also resident elsewhere, but you remain in scope of the Italian system.
Yes. If you are resident in two countries, the applicable treaty applies a tie-breaker (permanent home, centre of vital interests, habitual abode, nationality) to assign a single treaty residence. It does not remove Italian domestic residency but decides which country taxes what.
