How Italy decides tax residence
Each test is recorded separately with its own ID. Meeting or missing one test does not settle residence on its own.
Physical presence for most of the tax period
Physical presence in Italy for most of the tax period is a standalone criterion from 2024. Any fraction of a day spent within Italy counts toward the total, and non-consecutive periods are added together.
Civil-law residence or domicile
A person is also resident if, for most of the tax period, they have their residence within the meaning of the civil code, or their domicile, in Italy. Domicile is defined for tax purposes as the place where the person's personal and family relationships mainly develop, which gives priority to those relationships over economic ones.
Enrolment in the resident population registry
Enrolment in the resident population registry for most of the tax period remains a criterion, but since the 2024 reform it is a rebuttable presumption that admits contrary proof rather than an absolute one. For periods up to 2023, the former rules apply.
Italian citizens moving to a privileged tax regime
Italian citizens removed from the resident population registry who move to a state or territory on the privileged tax regime list are presumed resident in Italy unless they prove otherwise. The 2024 reform did not change this rule, and Switzerland was removed from the list from 1 January 2024.
Arriving, leaving and part years
The criteria are tested for most of the tax period (183 days, or 184 in a leap year) within a calendar year, adding non-consecutive periods (IT-RES-01 to IT-RES-03). Check Circular 20/E and the relevant tax treaty for the year of arrival or departure.
Reporting duties to check
- Registry and consular declarations on moving abroad. Circular 20/E recalls that Italian citizens must declare a transfer of residence abroad to the consular office within 90 days, alongside municipal registry declarations, and that registry status is relevant to the presumption in IT-RES-03.

- Optional substitute tax for new residents (article 24-bis TUIR). An option for individuals who transfer their tax residence to Italy to pay a substitute tax on foreign-source income. The rules were amended by Decree-Law 113/2024 and by Law 199/2025, so check the current amount and conditions in the official text. Source
Social security
Within the EU, a person is covered by one country's social security system at a time, and which one depends on work situation and residence, not nationality. Check the EU coordination rules and any bilateral agreement for work involving non-EU countries.
Living base
EU citizens can move to Italy under EU free movement rules, with permanent residence after a continuous 5-year period of legal residence. Others generally need a visa and a residence permit. A permit does not decide tax residence, which follows article 2 of the TUIR.
How visas, permits and tax residence differ
Citizenship
The Ministry of the Interior states that foreign nationals who have resided in Italy for at least ten years can apply for citizenship, among other requirements; citizenship by marriage is handled by the prefecture. Decree-Law 36/2025, converted by Law 74/2025, limited automatic citizenship by descent for people born abroad who hold another citizenship to the exceptions in article 3-bis of Law 91/1992. The Ministry of Foreign Affairs states that Law 91/1992 recognises the right to hold multiple citizenships.
Questions to take to a professional
- How should my days of physical presence in Italy be counted, including fractions of a day?
- Where do my personal and family relationships mainly develop, and does that place my domicile in Italy?
- If I am enrolled in the registry, what evidence could rebut the presumption of residence?
- Does the presumption for Italian citizens in privileged tax regime countries apply to me?
- Would the article 24-bis option or any other regime for new residents apply, and what are the current amounts and conditions?
- If another country also treats me as resident, how does the relevant tax treaty tie-breaker apply?
- Do the 2025 descent rules affect any claim to Italian citizenship in my family?
