Italian Corporate Tax (IRES and IRAP) for Foreign Companies 2026: Complete Guide
When a foreign entrepreneur decides to incorporate an SRL in Italy or establish a branch, taxes are inevitably the next question. Italy's corporate tax system revolves around two pillars: IRES (national corporate income tax at 24%) and IRAP (regional production tax at 3.9%). Whether you are comparing Italy's corporate structure to a US LLC or evaluating the Impatriate Regime's 70% tax exemption, understanding what you owe, what you can deduct, and how regional rules affect your bottom line is the difference between a profitable Italian operation and an expensive surprise. This guide explains how both taxes work for foreign-owned companies and which strategies advisors use to reduce the combined effective rate below the headline 27.9%.
What Is IRES? Italy's Corporate Income Tax Explained
IRES (Imposta sul Reddito delle Societa) is the national corporate income tax at a standard rate of 24% since 2017. It applies to the worldwide taxable income of Italian-resident companies (such as an SRL or SPA) and to the Italian-source income of non-resident entities with a permanent establishment. Taxable income is calculated by subtracting deductible costs from total revenues, with Italy's civil-law tax code prescribing treatment for depreciation, provisions, losses carried forward, and intercompany transactions. For a foreign-owned SRL with EUR 500,000 in revenue and EUR 350,000 in deductible expenses, IRES equals EUR 36,000 (24% of EUR 150,000 taxable income).

Many foreign clients focus exclusively on the 24% IRES rate and forget about IRAP, regional surtaxes on IRES, and municipal taxes. I always recommend planning for an effective combined rate of 27 to 31% depending on the region and municipality. Surprises at year-end are far more expensive than proper upfront planning.
Understanding IRAP: The Regional Production Tax
IRAP (Imposta Regionale sulle Attivita Produttive) is uniquely Italian — a tax on the net value of production rather than on profit. The standard national rate is 3.9%, though each region may adjust it by up to 0.92 percentage points. Unlike IRES, which targets net profit, IRAP targets revenues minus raw materials, purchased services, and certain personnel costs, meaning you may owe IRAP even with zero profit. A digital consultancy SRL in Milan with EUR 400,000 revenue, EUR 150,000 in subcontractor costs, EUR 100,000 in rent, and EUR 120,000 in salaries would owe roughly EUR 6,240 at Lombardy's 3.9% rate. Rates in major business hubs like Milan, Rome, and Turin are typically 3.9%, but verify with your commercialista — Trentino-Alto Adige sets rates at the provincial level, and some regions apply category-specific surcharges.
When Does a Foreign Company Owe Tax in Italy?
A foreign company triggers full IRES and IRAP liability when its activities create a permanent establishment (PE, or "stabile organizzazione") in Italy. Under Italian law aligned with OECD guidelines, a PE exists when a foreign company operates through a fixed place of business (office, branch, factory) or through a dependent agent who habitually concludes contracts on its behalf. Without a PE, you generally owe only withholding taxes on specific Italian-source income such as dividends, royalties, or service fees.
A UK-based software company selling online to Italian customers with no physical presence generally does not create a PE. The same company hiring a local sales representative in Milan who signs contracts on its behalf likely creates one and becomes subject to full Italian corporate taxation.

I have seen foreign companies structure their Italian market entry specifically to avoid PE status, using independent agents or distributors rather than employees. This is legitimate tax planning, but the line between an independent contractor and a dependent agent is thinner than most entrepreneurs think. Italian tax authorities scrutinize these arrangements carefully.
Choosing Your Tax Structure: SRL vs Branch
The SRL (Societa a Responsabilita Limitata) is the most popular vehicle for foreign entrepreneurs. It provides limited liability, requires minimum share capital of just EUR 1 (EUR 10,000 is standard for banking credibility), and automatically becomes an Italian tax resident subject to IRES on worldwide income and IRAP. It files an annual corporate tax return (Modello REDDITI SC) by the November 30 deadline.
A branch (filiale) is not a separate legal entity but an extension of the foreign parent. For tax purposes, it is treated as a PE subject to IRES and IRAP on Italian-source income, but profits and losses flow directly to the parent company's tax return — beneficial if the parent is in a lower-tax jurisdiction. For most foreign entrepreneurs, the SRL is preferred because limited liability protection outweighs the modest additional compliance cost.
Deductions, Depreciation, and Interest Limitations
Italian tax law (TUIR) allows SRLs to deduct employee salaries, social contributions, rent, professional fees, cost of goods, utilities, insurance, advertising, travel, and depreciation at prescribed rates. Meals and entertainment are 75% deductible up to daily caps (EUR 70 for employees, EUR 130 for clients). Non-deductible expenses include penalties, IRES and IRAP themselves, entertainment above legal caps, and costs related to tax-free income. Italy limits net interest deductibility to 30% of EBITDA under EU ATAD rules, with excess carried forward indefinitely. The 2026 Budget Law reintroduced iper-ammortamento (super-depreciation), allowing up to 220% deduction for qualifying green assets — see our guide to tax incentives for foreign companies in Italy for details on this, the Patent Box, and R&D credits.
Withholding Taxes and Cross-Border Payments
When a foreign company receives Italian-source income, withholding taxes apply independently of IRES and IRAP. Dividends to a foreign corporate shareholder face a 26% withholding tax, though most double taxation treaties reduce this to 5%, 10%, or 15%. Under the EU Parent-Subsidiary Directive, dividends to a qualifying EU parent holding at least 10% are exempt. Royalties are also subject to 26% (reduced by most treaties to 5–10%). Interest payments are generally exempt under EU law and most treaties if at arm's length and properly documented. A US company receiving dividends from its Italian SRL must consider both the Italian WHT (potentially treaty-reduced) and the US foreign tax credit.
Filing Deadlines and Compliance
For 2026, IRES and IRAP advance payments are due in two installments: June 30 (40% of the previous year's liability) and November 30 (the balance). New companies pay based on a reduced "minimum advance" calculation. The annual corporate tax return (Modello REDDITI SC) is due by November 30, 2026, for the 2025 fiscal year. Transfer pricing documentation for related-party transactions must be prepared annually and made available within 10 days of a tax authority request.

Missing a filing deadline in Italy triggers automatic penalties that start at 2% of the unpaid tax and can escalate to 30% for significant delays. Interest on late payments accrues at the legal rate (approximately 2.7% for 2026). For foreign companies unfamiliar with the Italian calendar, the single most valuable service a commercialista provides is simply making sure every deadline is met on time.

Frequently Asked Questions
How much corporate tax does a foreign-owned SRL pay in Italy?
A foreign-owned SRL pays IRES at 24% on taxable income plus IRAP at approximately 3.9% on the value of production. Including regional surtaxes (typically 1.73%) and municipal surtaxes (around 0.92%), the combined effective rate typically falls between 27% and 31%.
Do I need to pay IRES if I only sell online to Italian customers without a physical presence?
Generally, no. Without a permanent establishment in Italy — no office, no employees, no dependent agent authorized to conclude contracts — you are not subject to IRES or IRAP on Italian sales revenue. However, you may owe VAT (IVA) if cross-border sales exceed the EU B2C threshold of EUR 10,000 per year, requiring Italian VAT registration and periodic returns.
Is it better to open a branch or an SRL from a tax perspective?
An SRL provides limited liability and is a separate legal entity, paying IRES on worldwide income. A branch offers no liability shield but allows profits and losses to flow directly to the parent's tax return, which can help if the parent is in a lower-tax jurisdiction. For most foreign entrepreneurs, the SRL is preferred because liability protection and banking credibility outweigh the modest compliance overhead.
