Italy's 183-Day Tax Residency Rule
Being present in Italy for the greater part of the calendar year – 183 days, or 184 in a leap year – makes you an Italian tax resident. Here is exactly how the count works.
Last verified: July 2026
In short: you become an Italian tax resident if you are present in Italy for the greater part of the calendar year – 183 days in a normal year, 184 days in a leap year. Under the 2024 reform, any part of a day in Italy counts, so arrival and departure days both count. Registration in the resident population register (anagrafe), a habitual home, and personal or family domicile are alternative routes into residency.

The rule
Italy treats you as a tax resident for a tax year if any one of its residency tests is met for the greater part of that year. The physical-presence test is the one travelers watch. Two points decide most real cases:
- The greater part of the year means 183 days. "The greater part of the year" is more than half the calendar year. The Agenzia delle Entrate quantifies this as at least 183 days in a normal year and 184 days in a leap year, when February adds a day.
- A day means any part of a day. Since the 2024 reform, physical presence is measured in fractions of a day (frazioni di giorno). Any part of a day you are physically in Italy counts as a full day, so both your arrival day and your departure day count.
How to count it
- List every Italy trip with arrival and departure dates.
- Count each day you were physically present for any part of the day, including arrival and departure days.
- Total the days inside the calendar year, 1 January to 31 December.
- If the total reaches the threshold for that year – 183 in a normal year, 184 in a leap year – the physical-presence test is met.
Example. Exactly 183 days in Italy in one calendar year.
In 2026 (a normal year) 183 days is the greater part of the year, so you are resident. In 2028 (a leap year) the year has 366 days, so 183 is not more than half – you would need 184. The same 183-day stay makes you resident in 2026 but not in 2028.
Beyond the day count
The physical-presence count is one route in, not the only one. Italy can also treat you as resident for the tax year if, for the greater part of the year, you are registered in the resident population register (anagrafe), you have your habitual abode (residence) in Italy, or your domicile is in Italy. Since 2024, anagrafe registration is a rebuttable presumption rather than conclusive proof, and domicile is defined as the place where your personal and family relationships are principally developed. If another country also claims you, a double-tax treaty decides residency through tie-breaker rules such as permanent home and centre of vital interests.

How many days can you stay in Italy without becoming a tax resident?
Up to 182 days. Being present for the greater part of the calendar year makes you resident, which is 183 days in a normal year and 184 in a leap year.
Does Italy count the calendar year?
Yes. Residency is measured over the calendar year, 1 January to 31 December, and you are resident if a test is met for the greater part of it.
What changed in 2024?
A physical-presence test was added that counts fractions of a day, so arrival and departure days both count, and anagrafe registration became a rebuttable presumption.
