Registering residency at the comune (Step 2) has a fiscal shadow: it feeds into whether Italy considers you a tax resident — the status that makes your worldwide income taxable in Italy. This page is orientation, not tax advice; the rules below are the national baseline.
When you become a tax resident
Tax residency is automatic — you never apply for it. Under art. 2 of the TUIR (as reformed from 1 January 2024 by D.Lgs. 209/2023), you are an Italian tax resident for a calendar year if, for the majority of the year — more than 183 days (184 in leap years), counting fractions of days — any one of these holds:
- your residence (habitual abode, civil-code sense) is in Italy;
- your domicile is in Italy — now defined as the place where your personal and family relations principally develop;
- you are physically present in Italy.
Being registered at the anagrafe for most of the year makes you presumed resident — since the 2024 reform this presumption is rebuttable with evidence you actually lived elsewhere (before 2024 it was conclusive).
No split year
Italian law has no split-year rule: you are either tax resident for the whole calendar year or not at all (only the treaties with Switzerland and Germany provide mid-year splits). In practice:
- arrive in the second half of the year (fewer than 183 days) → normally non-resident for that whole year; only Italian-source income is taxable;
- arrive in the first half → resident for the whole year, worldwide income taxable, with treaty relief for what was earned before the move.
What tax residency means
Residents pay IRPEF (personal income tax) on worldwide income — currently 23% up to €28,000, 35% to €50,000, 43% above — reduced by deductions and credits. Non-residents are taxed on Italian-source income only.
Double taxation is managed by Italy’s network of around one hundred tax treaties (all EU states included): they decide which country may tax what, and foreign tax credits are claimed in your Italian return.
Your first return
Italian income tax is self-assessed — nobody sends you a bill. For your first resident year N, you file in year N+1:
- form 730 by 30 September — employees and pensioners; a pre-filled version is available online with SPID or CIE (Step 4 pays off here);
- form Redditi PF by 31 October — everyone else.
Employment income is withheld at source by your employer during the year, so for many employees the first 730 is a formality — or a refund.
Common pitfalls
- Counting only the 183 days. Since 2024, physical presence is itself a criterion (fractions of days count), and domicile follows your personal and family ties — a family settled in Italy can make you resident even if you commute abroad.
- Not closing tax residency in the country you left — both states may claim you; treaty tie-breakers then decide, but you must document your ties.
- Assuming only post-arrival income is taxed in an arrival year where you are resident — the whole year’s worldwide income is in scope, subject to treaty relief.
- Missing the first filing deadline because no authority contacted you.
Next step
If you moved with family, one more piece of paperwork may matter more than any of this: the residence card for a non-EU spouse or relative.
