Tax residency in Italy: how the day count works
Italy treats you as tax resident once you are present for the greater part of the calendar year: at least 183 days, or 184 in a leap year. Since the 2024 reform, fractions of a day count as full days. Physical presence, a habitual abode or your domicile in Italy can each trigger residency on its own.
What is the day threshold in Italy?
Italy makes you tax resident if, for the greater part of the tax year, you are physically present on Italian territory, have your residence (habitual abode) there, or have your domicile there. Greater part means at least 183 days in an ordinary year and 184 in a leap year. The criteria were rewritten by Legislative Decree 209/2023, effective from 2024, and are explained in English by the Agenzia delle Entrate and in PwC's Italy summary.
The reform made pure physical presence an independent trigger. Before 2024 you could argue that days alone did not decide; now 183 counted days in a calendar year settle it, whatever your registrations say.
| Day threshold | 183 days (184 in a leap year) |
|---|---|
| Counting window | Calendar year |
| Partial days | Fractions of a day count as full days since 2024 |
| Other triggers | Habitual abode, domicile (personal and family ties), Anagrafe registration as rebuttable presumption |

Calendar year or rolling window?
Calendar year. The Italian tax year is the calendar year and the greater-part test runs across it, resetting on 1 January. A stay that straddles the year-end, say October to April, does not reach 183 days in either year on presence alone. Note the contrast with Portugal's rolling 12-month window and with Germany's continuous six-month stay, both of which would catch that same pattern.
There is no split year: cross the threshold in any month and you are resident for the entire year.
Do partial days count?
Yes, explicitly. The 2024 reform wrote into the law that fractions of a day count as days of presence. A late-evening arrival in Rome adds a day; so does a morning departure. Day trips across the border from Switzerland or France add full days too. If your plan for the year is anywhere near 175 days, this is where the margin goes.
What else can make you resident besides days?
Three things, each sufficient on its own for the greater part of the year. Residence in the civil-law sense: your habitual abode, the place you actually live. Domicile, redefined in 2024 as the place where your personal and family relationships mainly develop, which pulls in people whose partner and children live in Italy. And enrolment in the Anagrafe, the resident population registry, which since 2024 is a rebuttable presumption rather than conclusive proof: if you forgot to deregister when you left, you can now prove you actually lived abroad, but the burden is yours.
A worked example with 2026 dates
Two stays, 189 counted days
A designer spends 15 March to 20 June 2026 in Milan, then 1 September to 30 November in Florence. Arrival and departure days count in full.
| Stay | Dates | Days |
|---|---|---|
| Spring | 15 Mar to 20 Jun 2026 | 98 (17 + 30 + 31 + 20) |
| Autumn | 1 Sep to 30 Nov 2026 | 91 (30 + 31 + 30) |
| Total in 2026 | 189 of 183 |
189 days is over the 183-day line for 2026, so Italy treats her as tax resident for the whole year on physical presence alone. To stay under, she would have had to cut seven days from either stay, and because fractions count, shaving trips by moving flights to just after midnight does not work in her favor.
How do I track my days for Italy?
Count every day with any Italian presence, per calendar year, including day trips. Keep boarding passes and card statements; since the reform, the day tally itself is what decides.

Frequently asked questions
Is the Italian threshold 183 or 184 days?
Both, depending on the year. The law requires presence for the greater part of the tax year: 183 days in an ordinary 365-day year, 184 days in a leap year. 2026 is not a leap year, so the 2026 threshold is 183 days.
Do arrival and departure days count in Italy?
Yes. Since the 2024 reform, fractions of a day count as full days of presence, so the day you land and the day you leave both go on the tally, however short the stay.
Does registration in the Anagrafe still decide residency?
It matters, but less than before. Until 2023, being registered in the resident population registry for the greater part of the year made you resident with no way to argue otherwise. Since 2024 the registration is a rebuttable presumption: you can prove you actually lived abroad.
Does Italy split the year when I move mid-year?
No. Italian domestic law has no split-year mechanism, so you are resident or non-resident for the whole calendar year. A few tax treaties, such as the one with Switzerland, provide split-year relief in specific cases.
