What Italian holding companies must do before their next distribution from a Brazilian subsidiary — and why the 1978 double-tax treaty does not solve the problem automatically
If your Italian holding company has a Brazilian subsidiary and a dividend distribution is in the pipeline, you have a narrow window to act. break into two sentences or restructure with no domestic remedy. The problem is not the rate. The problem is the structure of the treaty.
Yes, but not in the way most advisers assume. Brazil's Law 15,270/2025 reintroduces the taxation of dividends paid to non-resident legal entities and individuals, starting 1 January 2026. For almost thirty years — since Law 9,249/1995 — dividends paid by Brazilian companies were exempt from withholding tax. For anyone abroad, that ended on 1 January 2026.
Under the Italy–Brazil double-tax treaty, the maximum withholding rate on dividends paid to Italian tax residents is 15%. Article 10 of that treaty — signed in Rome on 3 October 1978 and still in force unchanged — sets the cap at 15% for portfolio holdings and at 10% where the Italian company holds at least 25% of the Brazilian subsidiary's capital. The new 10% domestic Brazilian rate therefore sits exactly at the treaty floor for controlling shareholders. Treaty relief does not reduce the rate further. The rate alignment is, in this respect, coincidental.
The structural problem lies in Article 23. Under paragraph 3 of Article 23 of the treaty, payments treated as Brazilian-source dividends are tax-exempt in Italy — consistent with the domestic participation exemption regime of Article 89 of the Italian income tax code (the Testo Unico delle Imposte sui Redditi, or TUIR). Italy operates a territorial regime under which foreign corporate profits are largely exempt from corporate tax in Italy; under the participation exemption (PEX) regime of Article 89(3) of the TUIR, 95% of the dividend received from a foreign subsidiary is exempt from Italian corporate income tax. Only 5% of the gross dividend is subject to Italian corporate income tax (IRES) at the standard 24% rate — an effective rate of approximately 1.2%.
The consequence is straightforward/clear. The exemption method eliminates Italian tax. It does not credit the Brazilian withholding tax. Under Article 23(3) of the treaty, the Italian company is exempt from Italian corporate income tax on dividends received from its Brazilian subsidiary — but no credit applies for income taxes paid in Brazil. The 10% withheld in Brazil is a final, irrecoverable cost.
Unlike in most common-law jurisdictions — where a foreign tax credit system, such as the one under UK Corporation Tax Act 2009 Part 2, allows a company to set foreign withholding taxes against its domestic tax liability on the same income — the Italy–Brazil treaty uses an esenzione, or exemption method, for dividend income flowing to Italy. There is no pooling mechanism, no excess credit carry-forward, and no re-characterisation route. The UK system allows unilateral relief even where a treaty gives no credit; Italy's TUIR does not offer an equivalent route when the treaty itself provides the exemption. The 10% Brazilian withholding therefore sits outside any relief framework.
The law provides that dividends on profits recognised/earned through 2025 — including prior years — resolved and approved by 31 December 2025, will remain exempt from taxation, even if payment of such dividends occurs after 2025, provided that payment terms follow the corporate resolution. This is a hard documentation rule. The corporate resolution must pre-date 1 January 2026. The payment may follow later, but only on the terms set out in that resolution.
In practice, this means two things. First, the shareholder resolution must have been passed and formally recorded under Brazilian corporate law before the year-end deadline — minutes, a registered ata de deliberação, dated unambiguously. Second, any variation in the payment schedule, such as a later instalment date or a change in the amount, risks breaking the exemption and pulling the entire distribution into the 2026 regime. The Brazilian Federal Revenue's guidance addresses add a closing full stop and complete the sentence including payment deadlines.
Italian holding companies that did not pass a qualifying resolution before 31 December 2025 cannot retroactively protect prior-year profits. That window has closed.
This is the question no competitor blog is asking — and it may be the most consequential one.
Dividends received by Italian resident companies from companies resident in countries other than tax havens — that is, countries where the actual taxation rate is lower than 50% of the domestic Italian taxation rate — are excluded from the IRES taxable base by 95% of their amount. The PEX relies on the Brazilian subsidiary not being classified as resident in a low-tax jurisdiction. With Brazil's standard corporate income tax rate plus the social contribution on net profit (CSLL) at 34%, the subsidiary has historically sat well above the Italian threshold. The PEX has therefore applied reliably.
Law 15,270/2025 introduces a partial credit for foreign beneficiaries where the sum of the Brazilian subsidiary's effective tax rate (ETR) in Brazil and the 10% dividend withholding tax exceeds 34%. The new law establishes a potential credit for foreign beneficiaries when the sum of the paying company's effective tax rate in Brazil plus the 10% dividend withholding tax exceeds a threshold of 34%. The law introduces a tax credit mechanism designed to cap the total tax burden for non-resident shareholders at Brazil's standard corporate tax rate, generally 34%. However, the formula is technical, and additional regulations are still pending.
The Pillar 2 qualified domestic minimum top-up tax (QDMTT) enacted in Brazil under Law 15,079/2024, effective from the 2025 fiscal year, changes the ETR calculation. For Brazilian subsidiaries in sectors with reduced IRPJ rates — financial institutions, for example, where the standard rate reaches 40%, or technology companies with tax incentives that reduce the ETR below 15% — the combined ETR analysis must be rerun. An Italian holding company whose Brazilian subsidiary benefits from regional tax incentives in a Zona Franca de Manaus or under a SUDAM/SUDENE regime may now find that the subsidiary's effective rate, recalculated under Pillar 2 rules, changes the tax classification on the Italian side. If the subsidiary is reclassified as a controlled foreign company (CFC) under Article 167 TUIR, the PEX does not apply at all, and income is imputed directly to the Italian parent. The Italian Tax Agency (Agenzia delle Entrate) issued a practice note on CFC recalculation following Pillar 2 interaction; Italian holding companies should run the ETR test before each distribution, not annually.
Nemo dat quod non habet — no one gives what they do not have. A treaty relief mechanism that exists on paper but cannot be activated gives nothing. Three specific risks deserve board-level attention.
First, the most-favoured-nation clause. The 1978 Italy–Brazil treaty does not contain a standard MFN clause in the dividend article comparable to those in more recent Brazilian treaties. There is no automatic treaty override that would import a 0% or reduced rate negotiated with a third country. Italian groups with investment structures routed through jurisdictions that signed later treaties with Brazil must take advice specific to that intermediate holding structure — not assume MFN symmetry.
Second, the ADI RFB interpretive acts. The Brazilian Federal Revenue published Ato Declaratório Interpretativo (ADI) RFB 3/2026 and 5/2026 — interpretive guidance on the application of Law 15,270/2025 to treaty-resident shareholders. These acts clarify the documentation requirements for a reduced treaty rate to apply at source. The guidance addresses the application of Law 15,270/2025, which introduces a 10% withholding tax on dividends paid to non-residents, effective 1 January 2026. Without correct documentation filed with the Brazilian subsidiary before the payment date, the 25% Imposto de Renda Retido na Fonte (IRRF) applicable to tax-haven residents may apply by default — at 25%, not 10%. Italy is not on the Brazilian tax-haven list, but the documentation burden has shifted to the Italian shareholder.
Third, the credit mechanism's pending regulations. The partial credit for the case where total Brazilian tax burden exceeds 34% may generate a refund or credit on the Brazilian side, but the administrative procedure for claiming it has not yet been fully specified by the Brazilian Federal Revenue. An Italian parent that distributes before those regulations are finalised risks paying 10% with no practical recourse until the regulations emerge — potentially a two-year gap.
Italian corporate shareholders benefit from the participation exemption regime, under which 95% of the dividend amount is exempt from taxation. The remaining 5% is taxed at the IRES rate of 24%, producing an effective rate on the dividend of 1.2%. No additional withholding applies on the Italian side when an Italian parent receives a dividend from its own foreign subsidiary. The issue is entirely the Brazilian outbound withholding — and, as explained above, the treaty structure means that 10% is not credited or offset in Italy.
For a concrete example: an Italian holding company receives EUR 1,000,000 in dividends from its Brazilian subsidiary in June 2026. Brazil withholds EUR 100,000 (10%). Italy taxes 5% of EUR 1,000,000 at 24%, yielding EUR 12,000 in IRES. The EUR 100,000 withheld in Brazil is not creditable. The combined effective rate on the gross dividend is 11.2%. Under the pre-2026 regime, the same distribution would have borne only the Italian IRES: EUR 12,000, an effective rate of 1.2%. The new cost is not marginal. It is a ten-fold increase in real tax drag, with no structural relief under current law.
In our files, the most common mistake is treating the Italy–Brazil treaty as a credit treaty without reading Article 23 carefully. Italian holding companies — and their advisers — apply the OECD Model framework instinctively and assume that a source-country withholding tax generates a corresponding credit in the residence state. Under the Italy–Brazil treaty, for dividends flowing to an Italian corporate parent, it does not. We also see shareholder resolutions that pre-date 1 January 2026 but were drafted without specifying the payment schedule precisely enough to satisfy the transition rule. The date of the resolution is necessary; it is not sufficient.
Can an Italian holding company claim a tax credit in Italy for the 10% Brazilian withholding tax on dividends?
Under the current Italy–Brazil double-tax treaty (Rome, 3 October 1978), Article 23 paragraph 3 exempts Brazilian-source dividends from Italian corporate tax. Because Italy uses the exemption method — not the credit method — for these dividends, no credit is available for the 10% withheld in Brazil. The withholding is a final cost at the Brazilian level.
Are dividends from profits earned before 2026 still exempt from the Brazilian withholding tax?
Only if a formal corporate resolution approving the distribution was passed and recorded under Brazilian corporate law on or before 31 December 2025, and the payment follows the schedule and terms set out in that resolution exactly. Any deviation — a different amount, a later instalment not provided for in the original resolution — may break the exemption and trigger the 10% withholding under Law 15,270/2025.
Does the new Brazilian dividend tax affect whether the Italian participation exemption applies?
Potentially, yes. The PEX under Article 87 TUIR requires the Brazilian subsidiary not to be classified as resident in a low-tax jurisdiction by Italian standards. For most Brazilian operating companies at the standard 34% rate, the PEX remains available. However, Brazilian subsidiaries benefitting from regional incentive regimes — where the effective tax rate may fall significantly — must be tested under the Pillar 2 ETR calculation following Law 15,079/2024. An adverse ETR result could reopen the CFC analysis under Article 167 TUIR and shut down the PEX for the holding company entirely.
