Italy Tax Residency (183-day rule)

Key parameters
Threshold	183 days
Period / Window	Calendar year (1 Jan – 31 Dec)
Counting	Any part of a day
Alternative	Registry enrollment, domicile test

You are an Italian tax resident for a calendar year if, for the greater part of the tax period — 183 days, or 184 in a leap year — you meet any one of four tests, in any order:

• Registry enrollment — you're enrolled in Italy's resident population registry (the Anagrafe). This creates a presumption of residency, but since a 2024 reform it can be rebutted with evidence that your actual life is based elsewhere.
• Domicile — the place where your personal and family relationships are mainly based is Italy. A 2024 reform narrowed this to personal and family ties, dropping the older focus on business and economic interests.
• Habitual residence — your stable, settled home under the Civil Code is in Italy.
• Physical presence — you're simply present in Italy for the greater part of the year, regardless of home, domicile, or family ties.

Meeting any one test makes you an Italian tax resident for the year, taxed on worldwide income. Falling short of all four makes you a nonresident, generally taxed only on Italian-source income.

Separately, Italian citizens who deregister and move to a country on Italy's low-tax blacklist are presumed resident regardless of which of the four tests they'd otherwise fail, unless they can rebut it with evidence of genuine non-residence.

The impatriate regime is a separate incentive for qualifying workers who relocate to Italy, distinct from the flat-tax regime for high-net-worth new residents — the two can't be combined.

• What it means — half of your qualifying Italian-source employment or self-employment income is excluded from income tax, regional tax, and municipal tax, rising to 60% if you have a minor child.
• Who can apply — employees and self-employed workers in a highly skilled role who haven't been an Italian tax resident for at least 3 tax years before the move, longer if you're returning to the same employer or corporate group. Your work also has to be carried out in Italy for most of the tax period, not just your residency status.
• What it gives — the exemption runs for 5 tax years, up to a set annual income threshold, and it can't be combined with the flat-tax regime for high-net-worth new residents.
• What it takes to keep it — you must remain an Italian tax resident for at least 4 of those 5 years. Leaving early triggers a full clawback of the tax already saved, plus interest, and a 10-year wait before you can reapply.

• Moving to a blacklisted low-tax country doesn't automatically cut ties. An Italian citizen who deregisters and relocates to a country on Italy's low-tax jurisdiction list is presumed resident by default, and has to prove genuine non-residence to rebut it.
• Registry enrollment is a rebuttable presumption, not an automatic trap. Since the 2024 reform, being on the resident population registry no longer irreversibly makes you resident — you can rebut it with evidence your actual life is based elsewhere.
• A flat annual tax can shelter foreign income for qualifying high-net-worth new residents. It covers foreign-source income for up to 15 years, but requires around a decade of prior non-residence to qualify.

Getting your residency status wrong and omitting foreign income you should have reported carries a penalty of 90% to 180% of the extra tax owed, increased by a third since the income is foreign-sourced — or a flat 120% if you never filed at all. Professional tax advice is strongly recommended in situations like this.

Settling in with room to spare

You move to Rome in January, rent an apartment, and spend 240 days in Italy over the year. You clear the physical-presence test easily, and your habitual residence is in Italy too, so you're an Italian tax resident either way.

Low physical presence, but domicile still in Italy

You take a long overseas assignment and spend only 60 days in Italy this year, but your spouse and children stay in the family home, clearly centring your personal and family life there. You fall well short of the physical-presence test, but the domicile test alone still makes you an Italian tax resident.

Moving abroad doesn't end residency by itself

You deregister from Italy's resident population registry and relocate to a country on Italy's low-tax list, assuming this ends your Italian tax residency. Because the destination is blacklisted, Italian law presumes you remain resident anyway, and you'd need to prove genuine non-residence to rebut it.
