Corporate Tax Residence in Italy: The Test, the 2024 Reform and Esterovestizione

What makes a company tax-resident in Italy?

Three tests decide the question, and Italian law treats them as alternatives, not as a checklist that has to be completed in full. Art. 73(3) TUIR sets out all three, and satisfying any one of them, for the greater part of the tax period, is enough to make a company or entity Italian tax-resident. Collective investment undertakings follow their own, self-contained rule instead: they are resident simply because they are established in Italy.

This page covers the company's own residence test. An individual's personal tax residence, including the 183/184-day test, is a separate question, governed by its own article of the TUIR.

The three tests are alternative, not cumulative

A company only has to fail all three tests to count as non-resident. Meeting just one, for the greater part of the tax period, is enough on its own. This structure did not change in the 2023/2024 reform. Only the content of two of the three tests did.

The registered office test: purely formal, and unchanged

The sede legale (registered office) test looks at the address stated in the deed of incorporation and recorded at the Register of Companies. It asks nothing about where decisions are actually taken, or where the business actually runs, and the 2023 reform left it untouched.

Place of effective management: the statutory definition

The second test, sede di direzione effettiva (place of effective management), now carries its own definition in the statute: "the continuous and coordinated taking of the strategic decisions concerning the company or entity as a whole." That wording did not exist before the reform, and it is the test most likely to matter for a company run by a board split across two countries.

Ordinary management on a principal basis: the statutory definition

The third test, gestione ordinaria in via principale (ordinary management on a principal basis), is defined as "the continuous and coordinated performance of the acts of current management concerning the company or entity as a whole." Where the second test looks at strategy, this one looks at day-to-day running, prevalently carried on in Italy.

What changed in the corporate tax residence test in 2023-2024?

The reform did not rewrite the rule. It replaced two labels with two statutory definitions and left everything else standing.

Two terms changed, both with their own statutory definition. The registered-office test and the "alternative, not cumulative" structure did not. Position as at 2026.

The old test: sede legale, sede dell'amministrazione, oggetto principale

Through the tax period that closed before 1 January 2024, Art. 73(3) TUIR, as it stood on 2023-01-01 used the same registered-office test, plus sede dell'amministrazione (seat of administration) and oggetto principale (main object of the business): also three alternatives.

The reform: two terms replaced, not a rewrite

D.Lgs. 209/2023, Art. 2, replaced only the second and third tests with the two new, statutorily defined ones described above. It left the registered-office test alone, and it left the "alternative, not cumulative" structure alone.

Why "oggetto principale" was dropped

The Agenzia delle Entrate states plainly why the main-object test disappeared: it calls it "a source of disputes and interpretative uncertainty" in Circolare 20/E. The underlying concept survives elsewhere in Art. 73, for a different purpose entirely, distinguishing commercial from non-commercial entities. It was removed as a residence test, not deleted from the TUIR.

What stayed exactly the same

Two things did not move: the registered-office test, and the rule that any one of the three tests is enough. A reform that touches two labels out of three, while leaving the third and the whole alternative structure untouched, is narrower than most summaries of it suggest.

When did the new residence test start to apply to my company?

Timing follows the company's own financial year, not one fixed date for everyone.

Entry into force: 29 December 2023

D.Lgs. 209/2023 entered into force on 29 December 2023. Its own commencement rule, Art. 7(2), applies the new residence test from the tax period following the one already in progress on that date, not retroactively to the period already underway.

Calendar-year companies: the new test applies from 1 January 2024

For a company whose financial year matches the calendar year, the tax period in progress on 29 December 2023 closed on 31 December 2023. The new test therefore applies from 1 January 2024, confirmed directly by Circolare 20/E, page 29.

A non-calendar financial year: the worked example

A straddling financial year needs its own check. The regulator's own worked example: a company with a financial year running from 1 April 2023 to 31 March 2024 keeps the old test until 31 March 2024, the close of the period already in progress when the decree entered into force, and the new test applies from 1 April 2024, the start of its next financial year. A company with an unusual year end should check this date deliberately, rather than assume 1 January by default.

What does "place of effective management" actually capture, and what doesn't count?

The place-of-effective-management test worries a non-resident owner more than any other, and the regulator's own guidance is more reassuring than most summaries suggest.

Only decisions "of a management nature" count

Per Circolare 20/E, quoting the reform decree's own explanatory report, only decisions "aventi contenuto gestorio" (of a management nature) are relevant to locating the place of effective management. A decision that is not of that kind does not move the needle, whoever makes it.

Shareholder oversight and monitoring do not count

The single most reassuring, least reported fact on this page: mere shareholder supervision or monitoring of management, and decisions by shareholders that are not of a management nature, do not count toward the place-of-effective-management test. Circolare 20/E states this directly. Routine oversight from abroad, on its own, is not the trigger.

No day-count, no meeting-count: a facts-and-circumstances test

No fixed day-count, meeting-count or other bright-line safe harbour exists anywhere in the statute or the circular. The regulator says this openly: the assessment runs case by case, because technology has separated where a business actually runs from where its strategic decisions are taken, and no settled international practice fills that gap.

Ordinary management on a principal basis: "prevalently" in Italy, not exclusively

The third test does not require every operational act to happen inside Italy. A company can keep establishments abroad and still satisfy this test, provided its ordinary management is carried on prevalently, not exclusively, in Italy.

What is esterovestizione? The reverse residence presumption for foreign companies

Esterovestizione is the rule most relevant to a founder using, or advised to use, a non-Italian holding structure over an Italian operating company.

The trigger: controlling an Italian IRES taxpayer

Under Art. 73(5-bis) TUIR, a foreign-incorporated company or entity that holds a controlling participation, as defined by Art. 2359(1) c.c., in an Italian-resident soggetto IRES (IRES taxpayer) is itself presumed Italian tax-resident, once one of two further conditions is also met.

Two alternative grounds: Italian control or an Italian-majority board

The presumption is triggered, alternatively, if the foreign entity is controlled, even indirectly, by persons resident in Italy, or if its consiglio di amministrazione (board of directors) or equivalent management body is composed in the majority of directors resident in Italy. A minority of Italian directors, on the wording of the statute, does not by itself trigger it.

The burden of proof is reversed

Once the trigger facts are present, the ordinary burden flips. The foreign entity is presumed Italian-resident, and it is the one that has to prove otherwise, not the Agenzia delle Entrate that has to prove residence.

Control-test timing

Control is tested at the closing date of the foreign controlled entity's own financial year, per Art. 73(5-ter) TUIR, not at some other point in the year chosen after the fact.

A narrower presumption for real-estate structures

A separate, narrower rule, Art. 73(5-quater) TUIR, catches structures whose assets sit predominantly in real-estate collective investment undertakings, where control runs through fiduciary companies or interposed persons on behalf of Italian residents. Most ordinary operating companies never meet this second, narrower test at all.

Can I run my Italian company from abroad without losing Italian tax residence? Two risk scenarios

No, and that is not a loophole to close. It follows directly from the registered-office test.

Scenario A: an Italian company run entirely from abroad

The registered-office test alone keeps an Italian-incorporated S.r.l., S.r.l.s. or S.p.A. Italian tax-resident, wherever its board actually meets or its strategic decisions actually get made. Distance from Italy does not, on its own, strip residence away.

The real risk in Scenario A: dual residence, not loss of residence

The risk that running an Italian company from abroad actually creates is the opposite one: a possible doppia residenza (dual residence), if the founder's home state applies its own test, such as an incorporation test or a "central management and control" test, to the same company. Italy does not lose the company. The other state may simply claim it too.

Scenario B: a foreign holding company run from Italy over an Italian subsidiary

The mirror-image scenario is the one Art. 73(5-bis) targets directly: a non-Italian parent controlling an Italian IRES subject, itself controlled by Italian residents or run by a board with an Italian-resident majority. Independently of the presumption, the same foreign parent can also be caught directly by the general test above, if its own effective management or ordinary management in fact sits in Italy, and it should still weigh how the 95% participation exemption applies if a disposal is ever on the table.

What happens if my company is tax-resident in two countries? The treaty tie-breaker

Double residence stays possible even after the reform, wherever a treaty partner state reaches the same conclusion under its own criteria. The Agenzia delle Entrate describes two different mechanisms operating across Italy's own treaty network, and conflating them is where most summaries of this topic go wrong.

The default rule: automatic, based on place of effective management

Most of Italy's tax treaties currently in force resolve a dual-resident company automatically, in favour of the state holding its place of effective management. No agreement between the two tax authorities is needed for this rule to operate.

Worked example: the Italy-UK Convention, Art. 4(3)

The actual ratified text of the Italy-UK Convention, Art. 4(3) states that a person other than an individual who is resident of both Contracting States "si ritiene ... residente dello Stato contraente in cui si trova la sede della sua direzione effettiva" (is deemed resident of the Contracting State in which its place of effective management is situated). That is the classic rule in its own words, not a paraphrase of it.

The exception: Canada and Chile use a mutual-agreement mechanism

Italy's treaties with Canada and Chile, named specifically by Circolare 20/E, instead use the newer, post-2017 OECD Model approach: the competent authorities of the two states have to reach a mutual agreement, considering the place of effective management, the place of incorporation, and any other relevant factor.

No agreement, no relief: why the exception is materially worse

If the two tax authorities do not agree, the company has no right to any relief or exemption under the treaty at all, a materially worse outcome than the automatic rule. The sequence in practice runs in four steps: confirm Italian residence under Art. 73(3) TUIR, check whether the other state also claims residence, identify which mechanism the specific treaty uses, then expect either an automatic answer or a negotiation with no guaranteed outcome. Most of Italy's treaties still follow the pre-2017 model. Anyone relying on a treaty other than the three named here should check its specific text rather than assume either mechanism applies by default.

Why does residence matter? Worldwide taxation and how it differs from a permanent establishment

Residence decides the size of the tax base, not just a formality for the incorporation file.

A resident company is taxed on worldwide income

An Italian tax-resident company is taxed in Italy on its worldwide income, wherever produced, subject to double-taxation relief where a treaty applies. The Agenzia delle Entrate's own IRES page restates the same residence criteria for this purpose.

A non-resident company is taxed only on Italian-source income

A non-resident company, by contrast, is taxed in Italy only on income treated as produced in Italy, under Art. 23 TUIR, typically through a permanent establishment rather than directly.

Permanent establishment is a different, non-resident concept

Stabile organizzazione (permanent establishment), under Art. 162(1) TUIR, is "a fixed place of business through which the non-resident enterprise carries on all or part of its activity in the territory of the State." It is a separate concept from residence and applies specifically to non-resident enterprises. A non-resident company with an Italian permanent establishment is taxed only on that establishment's Italian income, never on its worldwide income by virtue of the establishment alone. The two concepts should not be treated as interchangeable, however often they appear side by side in casual descriptions of Italian tax exposure.

Can I get advance certainty on my company's residence status?

No mechanism exists to lock in an answer before the fact.

No interpello is available for residence

The Agenzia delle Entrate states that establishing residence turns on a review of facts, something an interpello (advance tax ruling) procedure does not perform. A company cannot apply for advance clearance on where its place of effective management sits.

Residence is tested only on audit, year by year

Residence is self-assessed by the taxpayer, year by year, and tested only after the fact, on audit. There is no pre-clearance at any stage, which makes the record of where decisions were actually taken the only real defence if the question is ever raised.

What should a foreign founder actually do about this?

Three checkable actions follow directly from the sections above, without a single new fact added.

Document where strategic decisions are actually made

Keep a record trail, board minutes included, showing which decisions were genuinely of a management nature and where they were actually taken. That record is what an audit years later will actually look at.

Check your board's residence composition if using a foreign holding company

A board with a majority of Italy-resident directors, over an Italian IRES subject, is the specific, checkable trigger under Art. 73(5-bis). Reviewing board composition against that test is a five-minute exercise most founders never get around to doing.

Check your specific tax treaty, don't assume the automatic rule

Confirm which of the two mechanisms applies to the treaty between Italy and your own state of residence, rather than assuming either one by default. The answer changes what happens if the two states disagree.

Founders combining a corporate residence question with their own move to Italy will also want Company in Italy: flat tax for new residents in italy, which covers the individual regime rather than the company's own test addressed here. For the practical side of setting up or reviewing the structure itself, our incorporation service is where that conversation starts.

From our practice. Founders using a foreign holding structure over an Italian operating company often focus on where the shareholders live, when the statutory trigger is actually the board's residence composition. The most common confusion around the reform is treating it as a full rewrite of the residence test, when it replaced two terms and left the registered-office test, and the alternative structure, untouched. A non-calendar financial year is where the commencement date question comes up most often, and the answer always runs from the start of the company's own next financial year, not from 1 January by default.

The tests and dates above are given per the law and guidance in force as at the update date. Applying them to a specific structure should be checked with an adviser.
