ABSTRACT: Choosing between a branch and a subsidiary in Italy is the single most consequential structural decision a foreign company makes before entering the Italian market, yet most boards make it without understanding Italy's permanent establishment rules or the changes brought by the 2026 Budget Law. This article sets out the three legal structures available, their tax costs, their compliance burdens and the hidden risk that catches even well-advised companies off guard: the remote Italian employee who silently triggers a taxable presence. If you are a UK, US or Australian company with operations, clients or staff in Italy, the decision framework below is your starting point.

Should I open a branch or a subsidiary in Italy?

A British manufacturer testing the Italian market, a US technology firm hiring its first Italian sales manager, an Australian professional services group winning a long-term contract in Milan: all three face the same structural question before they start generating Italian revenue. The answer is not purely legal. It is a tax question, a liability question, and — increasingly — a compliance-cost one that the 2026 Italian Budget Law has made more demanding.

Ubi societas ibi ius — where there is a business, the law follows. That maxim captures Italy's approach perfectly: once your company generates a meaningful Italian economic footprint, Italian tax law will find you, whether you have incorporated locally or not.

Three structures exist. Understanding them in sequence is the only way to make an informed choice.

The three structures: representative office, branch and SRL

The ufficio di rappresentanza, or representative office, is the lightest option. It has no separate legal personality, may not carry out commercial activity, and does not constitute a permanent establishment (PE) under Italian law. It is suitable only for market research, liaison and promotion. The moment it starts concluding contracts or generating revenue, it ceases to qualify.

The branch — in Italian, sede secondaria — is an extension of the foreign parent. It has no separate legal personality. The parent bears unlimited liability for all obligations incurred through it. Permanent establishment is defined in Article 162 of the Italian Consolidated Income Tax Act (known by its Italian abbreviation, TUIR). A branch constitutes a PE from day one. Italian corporate tax comprises a 24% corporate income tax (IRES) and a 3.9% regional production tax (IRAP). Both apply to the Italian-source profits attributed to the branch. The branch must register with the Italian Chamber of Commerce (Camera di Commercio) and appoint a rappresentante preposto — a named individual resident in Italy responsible for the branch's legal and regulatory acts.

The subsidiary is a fully separate Italian entity, most commonly an S.r.l. (società a responsabilità limitata, a private limited company governed by Article 2463 of the Italian Civil Code). Foreign investors typically choose between a traditional S.r.l., which is more flexible and more respected by banks, and a simplified S.r.l.s., which is cheaper to set up but more rigid. The standard S.r.l. requires a minimum share capital of €10,000; the simplified S.r.l.s. can be incorporated with as little as €1. Because the subsidiary is a separate legal person, the parent's liability is limited to its capital contribution. The same IRES and IRAP rates apply to the subsidiary's profits. However, when profits are remitted to the non-resident parent as dividends, a 26% withholding tax applies under current Italian law — a figure non-EU groups especially need to factor into their investment returns.

Unlike in most common-law countries — where a branch and a subsidiary are simply two corporate formats that a company's accountant helps choose for operational convenience — Italy's distinction between the two carries immediate, automatic tax consequences that follow automatically from PE classification. A UK limited company opening a branch in Italy does not "choose" to become taxable in Italy: Italian law classifies the branch as a PE and taxes it accordingly from the first day of operation, regardless of whether the parent has taken any deliberate tax position. There is no grace period, no minimum revenue threshold and no filing opt-in. The obligation arises automatically under statute.

What is a permanent establishment in Italy and how does it affect my taxes?

Italy's PE rules have been expanding steadily since the OECD/G20 Base Erosion and Profit Shifting (BEPS) project reshaped international tax standards. Key changes introduced into Italian law include an updated definition of "personal permanent establishment," the introduction of an anti-fragmentation rule, and a new rule treating a significant and continuous economic presence in Italy as a permanent establishment, even if it lacks a physical presence.

That last point is critical for digital and service businesses. The "significant economic presence" concept means that non-resident digital companies can trigger a taxable presence in Italy through factors such as earning revenues from Italian customers, maintaining a local digital platform, the frequency of digital transactions, and the number of users.

The anti-fragmentation rule deserves particular attention. The anti-fragmentation rule prevents PE avoidance by treating as a PE the combined activities of linked and complementary companies operating in Italy, unless those activities are genuinely preparatory or ancillary. A foreign group that splits its Italian activities across several entities — one handling logistics, another handling customer support — cannot automatically claim that each unit is merely preparatory.

Italy's 2026 Budget Law (Law No. 199 of 30 December 2025) introduced sweeping corporate tax changes, from restructured income tax brackets to revised substitute tax rules, published in the Gazzetta Ufficiale and operative from 1 January 2026. For foreign market entrants specifically, the law reinforces Italy's alignment with the broad OECD PE definitions and tightens the transfer pricing documentation framework that applies once intra-group transactions reach materiality thresholds.

Transfer pricing rules apply to all cross-border transactions involving Italian resident entities, including the Italian PE of foreign companies. Both a branch (as a PE) and a subsidiary transacting with its foreign parent must apply arm's-length pricing and, above the relevant OECD materiality thresholds, prepare and maintain a formal Master File and Local File. The structure and content of the Italian Master File and Local File are established by the Implementation Decree of the Italian Inland Revenue Director dated 23 November 2020. Failure to maintain this documentation does not in itself trigger a tax assessment, but it removes the penalty protection that documented compliance provides during an audit.

Transfer pricing is one of the most scrutinised areas of Italian tax law for multinational groups. If your foreign company has an Italian S.r.l. that transacts with the parent company or other group entities, you must comply with Italian transfer pricing documentation requirements.

Does a foreign company's remote employee in Italy create a permanent establishment?

This is the question most foreign companies fail to ask until an Italian tax audit forces the issue. The answer is: it can, and it does so more often than directors expect.

A foreign employee who habitually works from home in Italy and who — even informally — negotiates or concludes contracts on behalf of the foreign employer may constitute a personal (dependent-agent) PE under Article 162 TUIR. The test is not whether the employee has a dedicated office or a title that says "representative." The test is whether the employee habitually exercises authority to bind the foreign company in Italy. A sales manager who sends proposals, agrees terms and issues order confirmations from their Milan apartment may well satisfy that test, even if every contract is formally signed abroad.

Italy's investment management exemption, incorporated into Article 162 TUIR, targets a dependent-agent fact pattern in which foreign entities delegate activity to Italy-based managers — and outcomes can turn on small factual distinctions about who negotiated, who instructed counsel and who "really" moved the transaction, making them hard to predict and harder to defend under audit.

The risk is not theoretical. The Italian Revenue Agency (Agenzia delle Entrate) has pursued PE assessments against foreign companies with Italian remote employees across the technology, professional services and distribution sectors. If a PE is later found to have existed undeclared, the company faces unpaid IRES and IRAP for all open tax years, plus penalties and interest. In Italy, the standard tax assessment period runs to five years after the year to which the income relates; for undeclared income, some authorities argue for an extended period.

The structural lesson is this: if your company employs someone in Italy who does more than administrative or support work, you must take a PE analysis before the employment starts — not after the first audit notice arrives.

How long does it take to set up an SRL in Italy as a foreign company?

For companies that conclude that a subsidiary is the right structure, the incorporation timeline matters for planning. A standard S.r.l. can be constituted in three to six weeks once all documents are in order, but the bottleneck is rarely the notarial deed itself. Every Italian company must have certified email (PEC) and at least one digital signature, without which it cannot file corporate documents, activate electronic invoicing or interact with key authorities. Opening a corporate bank account as a foreign director is often the biggest bottleneck, with strict KYC checks, possible requests for an Italian-resident director and timelines of two to six weeks.

The company will also need an Italian VAT number (partita IVA) and an Italian tax code (codice fiscale) for each director and shareholder. A registered office address in Italy is mandatory from the date of incorporation; a virtual office address is lawful for this purpose but will be scrutinised by banks and, potentially, by the Revenue Agency if it is the only Italian address the group uses.

Annual compliance costs for a trading S.r.l. — accounting, statutory audit where required, tax return preparation, transfer pricing documentation, corporate secretarial maintenance and certified email management — run to approximately €8,000–€15,000 per year for a company of modest size, before any advisory fees for structuring or dispute work.

A branch is cheaper to establish (no share capital, no incorporation notarial deed) but generates a comparable ongoing compliance burden, because it must file Italian tax returns, maintain Italian accounting records and comply with all Italian labour and employment obligations for its locally engaged staff.

The decision framework: how to choose in 2026

No single structure dominates in all cases. The decision turns on five variables.

The first is liability. A subsidiary caps the parent's exposure at its capital contribution. A branch exposes the parent's entire global balance sheet to Italian creditors. For companies entering a new, uncertain market, limited liability has a value that often outweighs the incorporation cost.

The second is tax efficiency on profits. Both structures pay IRES and IRAP at the same rates on Italian profits. The difference appears on extraction: a branch remits profits to the parent as attributed income, which is then taxed at the parent's home-country corporate rate (subject to any double-tax treaty with Italy). A subsidiary pays Italian dividends, subject to the 26% withholding tax — though treaty relief is available for UK, US and Australian parents under Italy's bilateral tax treaties, and may reduce that rate materially.

The third is transfer pricing exposure. A subsidiary trading with its parent immediately engages transfer pricing rules. A branch's dealings with its head office are also subject to PE attribution rules, which are conceptually similar. Neither structure avoids this discipline once intra-group transactions are material.

The fourth is the PE shadow. If your company already has Italian activities — contracts, employees, agents, a digital revenue stream — a formal PE analysis may reveal that a taxable presence already exists, making the "should we incorporate?" question secondary to the "have we already crossed the line?" question.

The fifth is the exit. A subsidiary can be sold as a share sale, attracting Italian participation exemption treatment under Article 87 TUIR for qualifying sellers. The participation exemption regime applies to Italian corporate entities and permanent establishments of non-resident companies; for qualifying capital gains, 95% of the gain is exempt, leaving an effective tax rate of roughly 1.2%. A branch cannot be sold as a share sale: a foreign buyer acquires an asset package, with less advantageous Italian tax treatment.

John Kenneth Galbraith observed that the conventional wisdom is frequently wrong in direct proportion to how comfortable it feels. The comfortable assumption for most Anglo-Saxon boards is that a single Italian hire is a payroll matter, not a tax restructuring. The 2026 legal environment in Italy makes that assumption increasingly expensive to hold.
