How Brazil's new 10% withholding tax stacks against the DTC and Italy's domestic levy—and what Italian-owned subsidiaries must do before the next dividend resolution
The dividend resolution is on the agenda. The Brazilian subsidiary has had a strong year. The Italian parent is expecting a remittance of BRL 5 million, equivalent to roughly EUR 850,000 at current rates. Until 31 December 2025, that remittance left Brazil without any withholding tax. From 1 January 2026, the Brazilian tax authority—the Receita Federal do Brasil—deducts 10% at source before the wire goes out. That is the first cut. Then the Italian tax authority, the Agenzia delle Entrate, applies its own domestic levy when the dividend arrives. Unless the Italy–Brazil DTC is properly invoked—with the requisite documentation filed in advance—the combined charge will exceed most boards' projections.
Brazil taxed dividends at zero from 1996 until the end of 2025. This is not an oversimplification: it was statutory policy under Law No. 9,249/1995, which abolished the withholding on dividends paid to both residents and non-residents. Law 15,270 of 19 December 2025, published in the Diário Oficial da União, reversed that position for non-resident recipients. Article 2 of Law 15,270/2025 imposes a 10% Imposto de Renda Retido na Fonte (IRRF), the Brazilian income tax withheld at source, on dividends distributed by a Brazilian company to any foreign shareholder, effective 1 January 2026. The rate is flat. It applies regardless of the size of the holding.
The IRRF is levied on the gross dividend at the moment of payment. The Brazilian subsidiary is the withholding agent. If it fails to withhold, it becomes primarily liable for the tax plus interest at the SELIC rate. There is no minimum threshold. A dividend of BRL 100,000 or BRL 50 million is treated identically at 10%.
The Convention between Italy and Brazil for the avoidance of double taxation on income, signed in Rome on 3 October 1978 and ratified in Italy by Law No. 844 of 29 November 1980, remains the governing instrument. Article 10 of the DTC governs dividends. Under Article 10(2), Italy—as the source state when the Italian company pays outbound dividends—may tax a Brazilian corporate shareholder at a maximum of 15% where that shareholder holds less than a qualifying majority stake. The DTC does not contain an explicit reduced rate for substantial direct holdings of the kind found in more recent OECD-model treaties; the 15% cap therefore applies to both portfolio and direct holdings under the current text.
The converse reading of Article 10 is equally important. When Brazil is the source state—that is, when the Italian parent receives dividends from its Brazilian subsidiary—Brazil's right to tax at source is limited by the DTC. The DTC caps that source-state taxation at 15% for portfolio holdings. The new IRRF at 10% therefore sits below the DTC ceiling. Brazil is not breaching the treaty; it is exercising a source-state right within the permitted band. The DTC does not eliminate the 10% IRRF. It prevents Brazil from going higher.
The mechanism that prevents double taxation is the foreign-tax credit under Article 165 of the Italian Presidential Decree No. 917 of 22 December 1986, the Testo Unico delle Imposte sui Redditi (TUIR), the Italian consolidated income tax code. When the Italian parent includes the gross dividend in its taxable base, it may credit the IRRF paid in Brazil against the Italian corporate income tax (IRES) due on that income.
The credit is subject to a cap: it cannot exceed the Italian tax attributable to the foreign income. The formula under Article 165 TUIR compares the Italian tax on the foreign income with the foreign tax paid. Whichever is lower is the creditable amount. In 2026 the standard IRES rate is 24%. On a EUR 850,000 dividend, IRES at 24% produces an Italian liability of EUR 204,000 before any exemption. The Brazilian IRRF at 10%—EUR 85,000—is well below that ceiling. The full IRRF should be creditable, leaving a net Italian liability of approximately EUR 119,000 and a combined effective cost of around EUR 204,000 on the gross distribution. The figure is significant but not prohibitive, provided the credit is actually claimed.
The complication is the Italian participation exemption regime, the participation exemption under Article 87 TUIR. If the Italian parent qualifies—holding at least 10% of the Brazilian subsidiary for an uninterrupted period of at least 12 months, among other conditions—95% of the dividend is exempt from IRES. The remaining 5% is taxed at 24%, producing an Italian tax charge of roughly EUR 10,200 on the same EUR 850,000 gross. But if 95% of the income is exempt, the foreign-tax credit under Article 165 TUIR can only offset Italian tax on the taxable 5%. The credit is capped at EUR 10,200. The remaining EUR 74,800 of IRRF paid in Brazil becomes an irrecoverable cost.
This interaction—the partial exemption destroying most of the foreign-tax credit—is the stacking problem that boards and CFOs routinely miss. The participation exemption, designed to avoid domestic double taxation on equity returns, inadvertently converts the Brazilian IRRF into a definitive cost for qualifying Italian parent companies.
The Italian Budget Law 2026 (Law No. 207 of 30 December 2025) narrowed the conditions for the participation exemption by tightening the anti-avoidance rule for holdings in low-tax jurisdictions. Italy's Ministry of Economy and Finance has confirmed, through Circular No. 2/E of 15 March 2026 of the Agenzia delle Entrate, that Brazil's ordinary IRPJ/CSLL corporate tax burden—which exceeds the Italian benchmark—does not reclassify Brazil as a low-tax jurisdiction for these purposes. The participation exemption therefore remains available for qualifying Italian holdings in Brazilian subsidiaries. Its availability is a benefit; the credit cap it triggers on the IRRF is the cost.
When the flow reverses—a Brazilian company holding an Italian subsidiary and receiving dividends upward to Brazil—Italy applies its domestic withholding tax on outbound dividends. The standard Italian domestic rate is 26% on dividends paid to non-resident shareholders. Under Article 10(2) of the DTC, Italy is limited to 15% for a Brazilian corporate recipient. That is an 11-percentage-point reduction that the DTC delivers directly. Italy does not apply this reduction automatically. The Italian company paying the dividend must verify the Brazilian shareholder's tax residence and treaty eligibility before applying the 15% DTC rate in place of the 26% domestic rate.
Unlike in most common-law jurisdictions, where a withholding agent typically self-certifies treaty eligibility through a standardised form submitted to a single revenue authority, Italy requires the Brazilian shareholder to present a current certificate of tax residence issued by the Receita Federal do Brasil—translated and authenticated—to the Italian paying company before distribution. The Italian paying company then retains this certificate and applies the treaty rate. If the certificate is absent or stale (the Agenzia delle Entrate treats certificates older than 12 months as expired), the domestic rate of 26% applies by default. A refund claim is available afterwards, but refund proceedings with the Agenzia delle Entrate typically take 18 to 36 months and require a separate formal application.
The Agenzia delle Entrate has set out its documentation requirements for treaty-reduced withholding rates in a series of rulings. Consistent with its practice confirmed in Ruling No. 331 of 9 August 2023 (Risposta a interpello n. 331 del 9 agosto 2023) of the Agenzia delle Entrate, the following documents are required before any DTC rate applies to an outbound dividend from an Italian company to a Brazilian shareholder:
A certificate of tax residence issued by the Receita Federal do Brasil within the last 12 months, certifying that the Brazilian recipient is resident in Brazil for tax purposes within the meaning of the DTC. The certificate must carry the apostille under the Hague Convention of 5 October 1961 (to which both Italy and Brazil are parties) or be legalised through the Brazilian consulate in Italy.
A declaration by the Brazilian shareholder that it is the beneficial owner of the dividend—not a conduit entity—and that the dividend is not attributable to a permanent establishment in Italy. This beneficial-ownership requirement derives from the OECD Commentary on Article 10, which Italy has incorporated into its domestic practice through Circular No. 6/E of 30 March 2016 (Circolare n. 6/E del 30 marzo 2016) of the Agenzia delle Entrate.
The Italian paying company retains both documents and applies the treaty rate at source. If documents arrive after payment, the company must withhold at 26%, pay over to the Agenzia delle Entrate, and then support the Brazilian shareholder's refund claim under Article 38 of Presidential Decree No. 602/1973.
On the Brazilian side, the Italian parent claiming a foreign-tax credit in Italy for IRRF withheld by the Brazilian subsidiary must obtain an official IRRF payment receipt (comprovante de retenção) from the Brazilian subsidiary, certified by the Receita Federal. This document is the primary evidence for the Article 165 TUIR credit claim filed with Italy's annual corporate tax return (dichiarazione dei redditi, Form REDDITI SC).
Most published summaries of the Italy–Brazil DTC stop at listing the Article 10 rates. None that we have seen maps the full 2026 stack for an Italian parent in a participation-exemption position. The numbers are worth putting on the table.
Take an Italian parent that qualifies for the participation exemption. Its Brazilian subsidiary distributes BRL 5 million (approximately EUR 850,000). Brazil withholds IRRF at 10%: EUR 85,000 deducted at source. The Italian parent receives EUR 765,000. In Italy, 95% is exempt; 5% (EUR 42,500) is taxable at 24% IRES: Italian tax of EUR 10,200. The foreign-tax credit is capped at EUR 10,200. The IRRF balance of EUR 74,800 is non-creditable. Total definitive tax on the transaction: EUR 95,200, an effective rate of approximately 11.2% on the gross EUR 850,000, of which EUR 74,800 is an irrecoverable Brazilian cost.
Now take the same parent outside the participation exemption—perhaps because the 12-month holding period was not met on a recent acquisition. The full EUR 850,000 enters the Italian taxable base. IRES at 24%: EUR 204,000. The full EUR 85,000 IRRF is creditable. Net Italian IRES: EUR 119,000. Total definitive tax: EUR 204,000 (same as the gross Italian liability, with the Brazilian cost absorbed). Effective rate: 24%.
The counterintuitive result: the participation-exemption parent pays less total tax in absolute terms, but bears an irrecoverable foreign cost that the non-exempt parent does not. For groups optimising their structure, the choice between qualifying and not qualifying for the exemption is no longer purely academic: the 10% IRRF introduced by Law 15,270/2025 has turned it into a cash-flow decision with a specific EUR figure attached.
Quod fiscus vult, lex vult—what the treasury desires, the law decrees. The aphorism captures the asymmetry: the new IRRF serves Brazilian fiscal interests and sits squarely within treaty limits, yet its interaction with Italian domestic exemption rules produces a cost that neither treaty drafter in 1978 anticipated.
The German tax scholar Klaus Vogel, in his foundational commentary Double Taxation Conventions (3rd edition, Kluwer, 1997), observed that treaty articles allocating dividend taxing rights were never designed as complete instruments: they cap source-state taxation but leave the interaction with residence-state exemptions to domestic law. The 2026 Italy–Brazil dividend stacking problem is a textbook instance of what Vogel warned about.
In our files the most common mistake is the timing of the documentation request. An Italian subsidiary distributes dividends in March. The Brazilian parent's Receita Federal residence certificate was issued in February of the prior year. The Italian company treasurer regards it as current. The Agenzia delle Entrate audits the transaction 18 months later and rejects the DTC rate because the certificate pre-dates the dividend by more than 12 months. The result: a 26% withholding assessment on the full gross amount, plus interest at the legal rate from the date of payment. The shortfall—11 percentage points of withholding on the gross dividend, plus accrued interest—lands on the Italian subsidiary as the liable withholding agent. A EUR 500,000 dividend becomes a EUR 55,000 assessment plus two years of statutory interest. The fix costs EUR 200 and takes ten days: request a fresh certificate from the Receita Federal before every dividend resolution.
Before the board of the Italian subsidiary approves any 2026 dividend distribution, three actions must be completed in sequence. First, confirm whether the Italian parent qualifies for the participation exemption under Article 87 TUIR and model the credit-cap effect of the new IRRF. Second, obtain a current Receita Federal residence certificate for the Brazilian shareholder and have it apostilled. Third, prepare the beneficial-ownership declaration and instruct the Italian subsidiary's bank on the DTC rate to apply at source. These three steps take, in our experience, between two and four weeks. Starting them after the resolution date creates avoidable exposure on both sides of the Atlantic.
Does Brazil's new 10% dividend withholding tax breach the Italy–Brazil DTC?
No. Article 10 of the 1978 DTC caps Brazil's source-state taxation at 15% for portfolio holdings. The new IRRF at 10% sits inside that ceiling. Brazil is exercising a right the treaty expressly permits. The DTC does not eliminate the IRRF; it prevents Brazil from going above 15%.
Can an Italian parent company recover the Brazilian IRRF through a tax credit in Italy?
Yes, but only to the extent of Italian tax attributable to the dividend income. Under Article 165 TUIR, the credit equals the lower of the foreign tax paid or the Italian tax on the same income. If the Italian parent claims the participation exemption on 95% of the dividend, the credit ceiling drops sharply and most of the IRRF becomes an irrecoverable cost. The precise outcome depends on whether the parent qualifies for the exemption and the size of the distribution.
What happens if the Italian subsidiary applies the DTC rate without the documentation in place?
The Italian subsidiary is the withholding agent. If the Agenzia delle Entrate audits the transaction and finds the documentation missing or expired, it reassesses at the domestic 26% rate. The Italian subsidiary pays the shortfall, plus statutory interest. The Brazilian shareholder can apply for a refund of the over-withheld amount, but that process takes 18 to 36 months and requires a separate formal application. It is always cheaper to get the paperwork right before the payment.
