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 tax period, 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.
“The majority of the tax period” is the statute’s own wording — it is not a 183-day test bolted on afterwards, and the arithmetic follows from it: at least 183 days of a 365-day year, 184 in a leap year. The Revenue Agency’s English page glosses it the same way.
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).
One asymmetry worth knowing if you also hold Italian citizenship: art. 2, comma 2-bis presumes Italian citizens who deregister from the anagrafe and move to a country not on the ministerial white list to be resident anyway, again unless they prove otherwise. Leaving can be harder to establish than arriving.
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
Art. 3, comma 1 draws the line: residents are taxed on all income they hold, non-residents only on income produced in Italy. That single sentence is what makes the residency question worth this much care.
Residents pay IRPEF (personal income tax) on that worldwide base. The bands in force for 2026 are 23% up to €28,000, 33% from €28,000 to €50,000, and 43% above — reduced by deductions and credits. The middle band was 35% through 2025; the 2026 budget law (L. 199/2025, art. 1, comma 3) cut it to 33% with effect from the 2026 tax period, so it first shows up in the returns filed in 2027. Expect older guidance — and pre-2026 calculators — to still say 35%.
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.
Proving it: the certificato di residenza fiscale
Residency happens to you, but proof of it does not. The moment you want a foreign payer to apply a treaty rate instead of withholding in full — on a pension, a dividend, a royalty, a salary from abroad — that payer wants Italy to say in writing that you are resident here.
The document is the attestato di residenza fiscale, issued by the Agenzia delle Entrate specifically so you can claim the benefit of a double-taxation convention or of EU law. One certificate can cover several kinds of income arising in the same foreign state.
You apply on the Agency’s own form, to any territorial office, by whichever of these suits you:
- the consegna documenti e istanze service in the authenticated area of the Agency’s site (upload the form, addressed to any Direzione Provinciale);
- in person at any office, which issues you a receipt;
- registered post with return receipt, enclosing a copy of the signer’s ID;
- PEC, with “Attestato di residenza fiscale” as the subject.
Neither the request nor the certificate is subject to stamp duty. A delegate can file for you with a formal power of attorney.
Do not confuse it with the comune’s certificato di residenza (Step 2), which proves where you live for civil purposes. This one is the tax authority certifying you to a foreign one.
What you hold abroad, not just what you earn
Worldwide taxation is the half of this that gets discussed. The other half is that Italy wants to know what you hold, and taxes some of it annually — and this is where a newcomer with a house or a bank account back home gets caught.
Declaring. Art. 4 of D.L. 167/1990 requires residents to list foreign investments, foreign financial assets and crypto-assets capable of producing income taxable in Italy in their annual return. It applies whether or not the asset produced anything that year, and it reaches beneficial owners, not only people whose name is on the account.
Paying. Two annual taxes ride alongside:
- IVIE, on property held abroad — 1.06% of its value, not due at all if the resulting amount is €200 or less, with a credit for any wealth tax paid where the property is;
- IVAFE, on foreign financial products — 2 per mille a year; for current accounts and savings books it is instead a fixed amount, the same one Italian accounts pay as stamp duty (Step 5).
So the first Italian return is not only about the year’s income. Gather the year-end balances and property values before you sit down to it.
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.
The article numbers change on 1 January 2027
Everything above cites the TUIR (D.P.R. 917/1986). Normattiva now shows artt. 2, 3, 11 and 24-bis as in force only until 31 December 2026: D.lgs 19 giugno 2026, n. 117 — published in Gazzetta Ufficiale n. 152 of 3 July 2026, in force since 4 July 2026 — re-enacts the income tax code as a new testo unico applying from 1 January 2027, repealing artt. 1 to 191 of the TUIR.
The substance of tax residency carries over. The numbering does not: art. 2 stays art. 2, but the new-residents regime moves from art. 24-bis to art. 246. From January, anything citing “art. 24-bis TUIR” is quoting a repealed text — which is why this page is due for re-verification before the cutover rather than six months after it.
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.
