Transfer Pricing for an Italian Subsidiary: Rules and Documentation (2026)

When a foreign group sets up an Italian SRL, the money that moves between the two companies is the first thing an Italian tax auditor looks at. Management fees, royalties, interest on a shareholder loan, the price paid for goods bought from the parent: each of these moves profit between countries, and Italy wants them priced as independent parties would have priced them. A five-person Italian subsidiary that pays its parent a yearly service charge is already inside the rules.

This guide describes the position applicable on 12 October 2026. It is written for the CFO or founder of a foreign parent company with a small or mid-sized Italian subsidiary. It explains the legal rule, the optional documentation that protects against penalties, the box in the tax return that activates that protection, and how far a small company can keep the exercise light. For the wider picture of how an Italian company is taxed, start with our overview of Italian taxes for foreign-owned companies.

The legal rule: article 110(7) TUIR and the arm's length principle

The core provision is article 110(7) of the Italian Income Tax Code (TUIR, Presidential Decree 917/1986). It applies to an Italian resident company and non-resident companies when one directly or indirectly controls the other, or both are controlled by the same entity. Income components arising from transactions between them are determined according to the conditions and prices that would have been agreed between independent parties acting in free competition and in comparable circumstances, if this produces a higher taxable income in Italy. A downward adjustment is only possible through the procedures in article 31-quater of Presidential Decree 600/1973: mutual agreement procedures, advance agreements, or a request by the company following a final adjustment made by a treaty partner.

The wording has referred to "free competition" (the arm's length principle) since 2017, replacing the old reference to "normal value". The details are in the Ministerial Decree of 14 May 2018, the Italian transfer pricing guidelines. It covers comparability, the choice of the most appropriate method, the aggregation of transactions, the arm's length range and the simplified approach for low value-adding services. The decree expressly draws on international best practice, and in practice Italian auditors read it together with the OECD Transfer Pricing Guidelines (2022 edition), which the Agenzia's documentation rules define as the 2017 Guidelines "and subsequent updates".

Two features of the decree matter most in an audit. First, article 6 treats a result that falls within the arm's length range of comparable transactions as compliant. If it falls outside, the tax authority adjusts it to bring it back inside the range, although the company may still present evidence that the transaction meets the arm's length principle. Second, the decree does not prescribe one method. It asks for the most appropriate method given the facts, and the burden of explaining that choice falls on whoever prepares the analysis.

A note on numbering. Italy is recodifying its tax legislation. The new consolidated income tax code (Legislative Decree 117/2026), the consolidated text on compliance and assessment (Legislative Decree 141/2026) and the consolidated text on tax penalties (Legislative Decree 173/2024) all apply from 1 January 2027. From that date the article references in this guide move to new numbers. For the returns being filed in autumn 2026, the provisions cited here are the ones in force.

Typical intercompany flows in a small Italian SRL

Most foreign-owned SRLs have a small number of recurring intra-group transactions. Each one needs a price, a contract and a reason.

Flow	Typical pricing approach	What an Italian auditor usually tests
Management fees and service charges from the parent	Cost plus a mark-up; 5% under the simplified approach for qualifying low value-adding services	Whether services were actually received, whether they duplicate local functions, and how costs were allocated
Italian SRL acting as distributor of group products	Transactional net margin method (TNMM) on operating margin, benchmarked against independent distributors	Whether the margin is stable and in range, and whether losses are consistent with a low-risk profile
Italian SRL providing services to the group (sales support, R&D, back office)	Cost plus a mark-up benchmarked against independent service providers	Completeness of the cost base and whether the mark-up reflects the functions performed
Intercompany loans and cash pooling	Interest rate benchmarked to comparable market terms, considering the borrower's credit profile	Rate, maturity, guarantees and whether part of the "loan" is really equity
Royalties for trademarks, software or know-how	Comparable uncontrolled price (licence agreements) or profit-based methods	Whether the intangible is used in Italy, who created its value locally, and the royalty base
Staff seconded or costs recharged	Usually pass-through or cost plus, depending on who benefits	Employment terms, who directs the work, and permanent establishment risk

Two points tend to surprise foreign groups. A service charge is not deductible in Italy simply because the parent invoiced it. The Italian company must be able to show what it received and why an independent company would have paid for it, so emails, reports, timesheets and allocation keys matter. And payments of interest and royalties to a foreign parent also raise withholding tax questions. Domestic withholding can be reduced by a tax treaty or EU directive only if the conditions are documented, and Italian interest deductibility is separately limited by the general 30% of EBITDA-type rule in article 96 TUIR. A loan priced at arm's length can still produce non-deductible interest.

Documentation: optional, but it changes the penalty

Italian law does not oblige a company to prepare transfer pricing documentation. What it offers is a trade: prepare documentation in the prescribed form, tell the Agenzia delle Entrate that you have it, and an adjustment in an audit does not carry the penalty for an inaccurate return. The Agenzia's own information page on the documentation regime presents it in exactly those terms.

The legal basis is article 1(6) of Legislative Decree 471/1997. Where an adjustment of transfer prices produces higher tax, the penalty in article 1(2) does not apply if, during the audit, the company delivers the documentation specified by the Agenzia and that documentation enables the arm's length nature of the prices to be checked. The same paragraph adds the condition many groups miss: the company must communicate that it holds the documentation, in the manner and within the terms set by the Agenzia. Without that communication, the penalty applies. A parallel rule in article 2(4-ter) protects the company, as withholding agent, against penalties when an adjustment of interest or royalties paid abroad leads to incorrect withholding.

The stakes changed with the 2024 penalty reform. For violations committed from 1 September 2024, Legislative Decree 87/2024 set the penalty for an inaccurate income tax return at 70% of the additional tax, replacing the previous 90%–180% range. As a purely illustrative calculation: an upward adjustment of €100,000 at the 24% IRES rate produces €24,000 of additional corporate tax. Without penalty protection, the penalty on that tax alone would be €16,800, before IRAP and interest. With suitable documentation, the tax and interest remain due, but that penalty falls away.

What the Master File and Local File must contain

The documentation rules are in the Provvedimento of the Director of the Agenzia delle Entrate of 23 November 2020 (prot. 360494), still the reference on 12 October 2026, as explained in Circular 15/E of 26 November 2021. Suitable documentation consists of two documents, both required, including for an Italian subsidiary of a foreign group.

The Master File describes the group: legal and ownership structure, the main value drivers, the supply chain for the main products and services, the main intra-group service arrangements, intangibles, intra-group financing, the consolidated financial statements and existing advance pricing agreements or rulings. In most groups it is prepared once at group level.

The Documentazione Nazionale, the Italian Local File, describes the Italian company: its management structure and reporting lines, business and strategy, competitors, and then each intra-group transaction that is not marginal. For each transaction or homogeneous category, the Local File sets out the amounts, the counterparties, a comparability and functional analysis, the method chosen and why it is the most appropriate, the search strategy for comparables, the arm's length range and the result, together with the critical assumptions. It must be accompanied by the annual accounts, a reconciliation between the figures used in the analysis and the financial statements, and copies of the intra-group agreements.

The Provvedimento also fixes the form. The Local File must be written in Italian; the Master File may be presented in English. The Agenzia confirmed in ruling 174 of 2024 that Italian is an essential requirement for the Local File, so a group Local File drafted only in English does not qualify. Both documents must be signed by the legal representative or a delegate with an electronic signature and time stamp applied by the filing date of the income tax return. Documentation must be prepared each year, covers only the year to which it relates, and must be kept until the assessment period expires.

The Agenzia is not bound to grant protection if the documentation, while following the required structure, is incomplete overall, lacks the time-stamped signature, or contains untrue information. It must, however, be treated as suitable when it gives auditors what they need to analyse the transactions, even if the auditors would have chosen a different method or different comparables. Partial omissions that do not compromise the analysis are not fatal. A company can also document only some of its transactions, in which case the protection covers only those.

The RS106 box: how the protection is activated

The communication required by article 1(6) is made in the income tax return. In the Redditi SC 2026 instructions, section 17.17 "Prezzi di trasferimento" asks every resident company in the article 110(7) situation to complete line RS106:

• box A if the company is directly or indirectly controlled by a non-resident company, which is the usual case for a foreign-owned SRL;
• box B if it controls a non-resident company;
• box C if it deals with a non-resident company where both are controlled by another company;
• the "Possesso documentazione" box if it has adopted the documentation regime; and
• columns 5 and 6 for the total positive and negative income components from transactions subject to article 110(7).

RS106 must be completed whenever the company has relevant intra-group transactions, whether or not it holds documentation. The "Possesso documentazione" box is the part that activates penalty protection. Ticking it without documentation that is signed and time-stamped on time is worse than not ticking it, because it states something untrue in the return.

For the 2025 tax year of a calendar-year company, the return is due on 2 November 2026: the Agenzia's filing page confirms the deadline moves from 31 October because that day falls on a Saturday. A group that wants protection for 2025 should plan to have both documents finalised, signed and time-stamped by then. Circular 15/E (section 9) leaves a limited fallback: the communication can also be made in a late or replacement return filed within 90 days of the deadline, with the documents signed and time-stamped by the date that return is actually filed, without prejudice to any applicable penalties. After those 90 days, the communication can still be made through the remissione in bonis procedure, in a supplementary return filed by the deadline of the following year's return and with payment of a minimum penalty. This works only if no audit has started and the documents were already signed and time-stamped within the 90 days. The Provvedimento also allows documentation to be completed or amended when a supplementary return is filed to correct transfer pricing errors that reduced taxable income, with the communication made in that return.

Simplifications for small companies and low value-adding services

There are two simplifications, and both are narrower than they look.

The first is for SMEs. The Provvedimento defines them as companies with turnover or revenue of no more than €50 million in the year documented, and excludes any company that directly or indirectly controls, or is controlled by, an entity that is not itself an SME. A qualifying SME may leave the transaction analysis in the Local File, including the comparable search, unchanged for the two following tax years. This applies only if the comparability analysis uses publicly available information and the comparability factors do not change significantly. In practice, this means a benchmark every three years instead of every year. But the control test excludes many foreign-owned SRLs: a €5 million Italian subsidiary of a group with €500 million turnover is not an SME for this purpose. The Master File and Local File are still prepared, signed and time-stamped every year; what is relaxed is the annual update of the transaction analysis.

The second is for low value-adding intra-group services. Article 7 of the 2018 Ministerial Decree allows the company to price such services as the total of direct and indirect costs plus a 5% mark-up, without a benchmark, provided specific documentation is prepared. The services must be supportive in nature, not part of the group's core business, must not use or create unique and valuable intangibles, and must not involve significant risk. Services the group also sells to independent parties never qualify. Section 7 of the Provvedimento lists what the documentation must contain: a description of each category of service, the beneficiaries, why they qualify, the business reasons and expected benefits, the allocation keys and why they are reasonable, the written agreements, the cost pool and the calculations. This is the natural home for the typical group recharge of accounting, IT support, HR administration and similar back-office functions. It is not a safe harbour for a management fee that is really a share of profits.

What happens in an audit

A transfer pricing audit usually starts as part of a general tax audit or a targeted questionnaire. The Agenzia's risk analysis can draw on what the company declared in RS106. Persistent losses in a distributor, large service charges relative to turnover, or royalties paid to a group company in a low-tax country are classic triggers.

When documentation is requested, it must be delivered within 20 days. If auditors then ask for supplementary information, it is due within 7 days, or a longer period depending on complexity if compatible with the audit timetable. If these deadlines are missed, the Agenzia is no longer bound to grant penalty protection. Auditors who reject the documentation must give specific reasons, and the assessing office can review that judgment when it imposes penalties.

If the auditors conclude that a price is outside the arm's length range, they propose an upward adjustment of taxable income. The company can contest it, settle it through the Italian assessment-with-adjustment procedure, or seek relief from double taxation in the parent's country through the mutual agreement procedure under the applicable tax treaty or the EU Arbitration Convention. Under article 43 of Presidential Decree 600/1973 the ordinary assessment period ends on 31 December of the fifth year after the return was filed, which is why the Provvedimento requires documentation to be kept for that period.

Secondary adjustments

deserve a mention because foreign groups often ask about them. Some countries treat the excess amount paid to a related party as a deemed dividend or a loan, with further tax consequences. Italy has no general statutory rule for secondary adjustments, as it reported in a survey of the EU Joint Transfer Pricing Forum. The Agenzia has nonetheless examined the consequences of a secondary adjustment in individual rulings, such as [ruling 233 of 2022] on the repayment of a deemed loan arising from an earlier royalty adjustment(https://www.agenziaentrate.gov.it/portale/documents/20143/4335071/Risposta+all%27interpello+n.+233+del+28+aprile+2022.pdf/f4c423b7-a563-a8d3-3884-b894b90e4e0c). The parent's own jurisdiction may also apply a secondary adjustment when Italy adjusts, and it may refuse a corresponding downward adjustment unless relief is sought through the treaty. The practical lesson is to resolve the primary adjustment with both countries in view.

Advance pricing agreements and cooperative compliance

A company that wants certainty in advance can apply for an advance agreement under article 31-ter of Presidential Decree 600/1973, covering among other things the method for pricing article 110(7) transactions. A unilateral agreement with the Agenzia binds both parties for the tax year in which it is signed and the four following years, unless the facts or law change, and the effects can be extended backwards to earlier years still open to assessment if the same circumstances applied and no audit has started. Bilateral and multilateral agreements, negotiated with the other country's tax authority, follow the terms agreed between the authorities and are subject to an admission fee scaled to group turnover. Details are on the Agenzia's advance agreements page, last updated on 7 May 2026. For most small subsidiaries an APA costs more than the risk it removes, but it can make sense for a large recurring royalty or a distribution model with volatile margins.

The cooperative compliance regime (adempimento collaborativo), strengthened by Legislative Decree 221/2023, is a separate route for large taxpayers with a certified tax control framework. Its revenue threshold is €500 million for 2026 and 2027 and falls to €100 million from 2028. It is not relevant to a typical small SRL.

VAT and customs: the same payment, different rules

Transfer pricing is a direct tax concept, but the same intra-group payments can have VAT and customs consequences. In the Arcomet Towercranes judgment of 4 September 2025 (C-726/23), the EU Court of Justice held that remuneration for intra-group services, set out in a contract and calculated with the TNMM, was consideration for a supply of services within the scope of VAT. The Agenzia delle Entrate's own position, restated in ruling 266 of 2024 and ruling 214 of 2025, is that a transfer pricing adjustment is relevant for VAT when it is contractually linked to specific supplies and changes their consideration, and outside VAT when it is a lump-sum reallocation of profit without that link. The result depends on how the intercompany agreement is drafted, so the VAT treatment should be decided when the agreement is written, not at year end.

Where the Italian SRL imports goods from the group, a year-end price adjustment can also change the customs value already declared at import. Distributors buying from a non-EU parent should agree with their customs adviser how adjustments will be reported, before the first one is booked.

A practical annual calendar

For a calendar-year Italian subsidiary, a realistic cycle looks like this

When	What to do
Before the year starts	Review intercompany agreements and pricing policies; update them for any new flows or restructuring.
During the year	Invoice service charges and royalties according to the agreements; keep evidence that services were received; monitor the operating margin of a distributor or service provider against the target range.
Year end (closing the accounts)	Calculate any year-end adjustment needed to land within the policy, decide its VAT and customs treatment, and book it before the accounts are closed. For the accounting and approval cycle, see how to read Italian company accounts.
Spring	Group finalises the Master File; Italian adviser drafts or updates the Local File in Italian, including the benchmark (or confirms that the SME roll-forward applies).
Before the return deadline	Legal representative signs both documents with electronic signature and time stamp; the return is filed with RS106 completed and, if applicable, the "Possesso documentazione" box ticked.
Afterwards	Archive the signed files and supporting evidence until the assessment period expires; be ready to deliver within 20 days of a request.

The return and other annual filings sit within the wider compliance cycle described in our Italian SRL tax deadlines and compliance calendar.

When a small subsidiary can keep it light

Not every Italian subsidiary needs a full documentation set every year. A proportionate approach for a small company usually rests on four questions.

1. How large are the intra-group flows relative to the Italian profit? If the only flow is a modest recharge of back-office costs, the realistic tax at stake may be small, and a well-documented cost-plus-5% file under article 7 may be enough.
2. Is the business model simple and stable? A low-risk distributor or service provider with a consistent margin is easier to defend than a company that makes losses one year and large profits the next.
3. Do you qualify as an SME under the Provvedimento? If the group is small enough, the three-year benchmark cycle meaningfully reduces cost. If it is not, assume an annual update.
4. What would a 70% penalty on a plausible adjustment cost compared with the documentation? That comparison, not a general rule, decides whether to opt into the regime.

Even a company that decides not to prepare a Master File and Local File should still have written intercompany agreements, a short pricing rationale, invoices that describe the service, and evidence that the services were received. That material does not give penalty protection, but it is what makes the deduction defensible. It also means RS106 is still completed correctly, with the relationship box and the amounts, simply without the documentation box.

Working with an Italian adviser

The group usually owns the transfer pricing policy and the Master File; the Italian side turns it into contracts, invoices, year-end entries, a Local File in Italian and a correct RS106. If that interface is currently left to chance, see how to choose an English-speaking accountant in Italy and the services we provide to foreign-owned companies.
