The Brazil–Poland Tax Treaty.
rates, services and how to claim.

When the Brazil–Poland tax treaty entered into force

The Brazil–Poland treaty — formally the Agreement for the Elimination of Double Taxation with respect to Taxes on Income and the Prevention of Tax Evasion and Avoidance, together with its Protocol — was signed in New York on 20 September 2022. It then travelled the full ratification path on both sides before producing any legal effect, and the sequence of dates matters because the treaty is in its first year of application.

On the Brazilian side, the National Congress approved the text through Legislative Decree No. 186 of 18 July 2025. The Agreement and its Protocol entered into force internationally on 5 November 2025, once both states had exchanged their instruments of ratification. Brazil then promulgated the treaty domestically through Decree No. 12.865 of 2 March 2026, published in the Official Gazette (DOU) on 3 March 2026, which carries the full authentic text in annex. On the Polish side, the official text was published in the Dziennik Ustaw 2025, item 1604.

The critical operational date is when the treaty starts to bite. Under Article 30(2), the Agreement produces effects — for taxes withheld at source and for other taxes — in respect of income and fiscal years beginning on or after 1 January of the calendar year following entry into force. Because entry into force was 5 November 2025, that first of January is 1 January 2026. In practice: a dividend, royalty or service fee paid from Brazil to Poland (or vice versa) on or after 1 January 2026 can be run through the treaty; a payment made in 2025 cannot.

Two structural points close the picture. First, the taxes covered are defined in Article 2(2): in Brazil, the federal income tax and the Social Contribution on Net Profit (CSLL); in Poland, personal income tax (PIT) and corporate income tax (CIT). The treaty does not reach any other tax — a limit that becomes decisive in the section on what the treaty does not cover. Second, the Agreement is authentic in Portuguese, Polish and English, but the final clause is explicit that in case of divergence the English text prevails — so the English wording is the one to read when a term is contested.

Who the treaty applies to: residence and beneficial ownership

The treaty applies to persons resident in Brazil, in Poland, or in both — the standard scope of a double-tax agreement. Residence is the gateway: only a resident of one contracting state can invoke the treaty against tax in the other. For a company, that ordinarily means it is liable to tax there by reason of its domicile, place of management or incorporation, a status a Polish company evidences through its tax residence and a Brazilian company through its registration and place of effective management.

Residence alone, however, does not unlock the reduced rates. For the four flows that carry a rate ceiling — dividends (Article 10), interest (Article 11), royalties (Article 12) and technical services (Article 13) — the treaty adds a second condition: the recipient must be the beneficial owner of the income. This is a deliberate anti-conduit filter. A Polish holding entity that merely passes the income through to a third party is not the beneficial owner, and the reduced rate does not attach. The concept works together with the anti-abuse machinery of Article 28 examined further below.

A distinction that recurs throughout the treaty is company versus partnership. The most favourable dividend ceiling, for example, is reserved for a beneficial owner that is a company — expressly excluding a partnership (a fiscally transparent vehicle). Groups structuring a Polish or Brazilian holding should confirm the legal form of the recipient at the outset, because it changes the rate. Where the entity is transparent, the analysis moves to the persons behind it, and the benefit may be tested at that level.

Finally, the treaty coexists with each country's domestic rules rather than replacing them. It limits what the source state may tax; it does not create a taxing right the source state's own law does not already provide, and it does not override domestic anti-avoidance legislation (see the Protocol point on thin capitalisation and controlled-foreign-company rules in the section on claiming benefits). For a first orientation to the cross-border terminology used here, the firm maintains an international tax glossary.

The treaty rates, article by article

The single most important thing to understand about the treaty rates is that each one is a ceiling, not a floor and not a standalone rate. The treaty caps the tax the source state may charge; it never obliges a state to withhold at that number. In practice Brazil applies the lower of (i) its domestic rate and (ii) the treaty ceiling. So where the domestic rate is higher than the ceiling — as with software royalties (15% domestic vs 10% treaty) — the treaty wins and the rate drops to 10%. Where the domestic rate is already at or below the ceiling — as with the new 10% dividend tax — the treaty changes nothing. Every ceiling below carries its band condition; a bare number is never the answer.

A recurring source of confusion is the most-favoured-nation (MFN) clause in Protocol §4. If, after signature, Brazil grants an OECD member state (excluding any Latin American country) a lower rate — or an exemption — than the 15% of Article 11(2)(b) on interest or the 15% of Article 12(2)(a) on trademark royalties, those Brazil–Poland ceilings are replaced by 10%. The clause is a floor of 10%, never below it: even if the trigger treaty grants less, Brazil–Poland only falls to 10%. Whether any triggering treaty is currently in force is a point to confirm at the date of the transaction, not a settled fact. The mechanics flow-by-flow, with the domestic column set out in full, live in the dedicated withholding-tax rates page.

One flow is deliberately absent from the table: capital gains. The treaty's Article 14 on capital gains was not part of the verified source set for this desk, so the firm does not state a treaty rate for gains on the disposal of Brazilian assets by a Polish resident — the domestic progressive rate (15% to 22.5%) is confirmed, but the treaty allocation is a point to confirm case by case rather than assert.

Technical services: the rare Article 13, independent of a permanent establishment

The feature that most distinguishes the Brazil–Poland treaty from a standard OECD-model agreement is that it contains a dedicated article on technical services. Under Article 13(2), fees for technical services arising in one state and paid to a beneficial owner resident in the other may be taxed at source at a ceiling of 10% of the gross amount. The decisive words are at source and gross: Brazil may withhold on the payment itself, without waiting for the Polish provider to have any physical presence in the country.

This is unusual. In a treaty without such an article, technical-service income is typically pushed into the business-profits or other-income rules, and the source state can often tax only if the provider has a permanent establishment there. Article 13 removes that argument entirely — taxation at source does not depend on a permanent establishment existing. It is precisely because the treaty handles services this way that Article 5 carries no "services-PE" day threshold: the drafters chose a clean 10% source cap over a days-counted presence test.

The definition is broad. Under Article 13(3), "fees for technical services" means any payment for services of a managerial, technical or consultancy nature, and Protocol §5 extends the same treatment to any remuneration for the provision of technical support or assistance. That sweep captures the bulk of intragroup service charges — management fees, engineering support, IT consultancy, technical assistance contracts. The article does carve out three cases that are not taxed as technical services: (a) payments to an employee of the payer; (b) payments for teaching in or by an educational institution; and (c) payments to an individual for services for that individual's personal use.

Two practical consequences follow. First, the treaty lowers the source tax on services from 15% to 10%: the Brazilian domestic withholding on technical and administrative service fees is 15%, and the Article 13 ceiling brings that to 10% for a qualifying Polish beneficial owner. Second — and this catches groups out — the reduction applies only to the income tax. The Brazilian CIDE contribution of 10%, which falls on the Brazilian payer of technical, administrative and know-how remittances, is a separate, autonomous levy that the treaty does not touch, because the treaty reaches only income tax and CSLL (Article 2(2)). So the typical combined load on a technical-service fee is 10% IRRF plus 10% CIDE, and only the first half is capped by the treaty. Structuring these charges — and defending their deductibility on the Brazilian side — connects directly to the firm's transfer pricing work, since Brazil's arm's-length rules affect the deductible base even where the treaty fixes the rate.

Permanent establishment: the 12-month rule

Where the treaty does turn on physical presence — for business profits rather than the flows above — the key threshold is the permanent establishment (PE) in Article 5. A PE is a fixed place of business through which an enterprise carries on all or part of its activity, and Article 5(2) lists the usual examples: a place of management, a branch, an office, a factory, a workshop, and a mine, oil or gas well, quarry or other place of extraction of natural resources.

The rule that most often decides a Brazil–Poland engagement is in Article 5(3): a building site, a construction or an installation project constitutes a PE only if it lasts more than twelve (12) months. Below that duration, the project does not create a taxable presence in the source state; cross it, and the enterprise's profits attributable to the site become taxable there. For Polish engineering, construction and industrial-assembly contractors — and for Brazilian contractors operating in Poland — this 12-month line is the single most important planning parameter, and it should be tracked from the real start of on-site work.

The treaty guards the threshold against slicing. Under the anti-fragmentation rule of Article 5(4), connected periods carried out by closely related enterprises, each lasting more than 30 days, are added together when testing the 12-month period — so splitting one project across affiliated companies does not reset the clock. Separately, Article 5(7) contains a broadened dependent-agent rule of the BEPS/UN type: a person who habitually concludes contracts, or plays the principal role leading to the routine conclusion of contracts that the enterprise then signs without material modification, creates a PE even without a fixed place of business.

Reading Article 5 alongside Article 13 explains an apparent gap: there is no services-PE threshold measured in days (no "183 days" test). That is by design. Because technical services are already taxable at source under Article 13, the treaty does not need a services-PE figure to reach service income — the two articles are complementary, and a Polish provider of technical services can face a 10% source tax with no PE at all, while a construction project escapes source taxation of its business profits until it passes 12 months. Getting an entry structure to sit on the right side of both lines is the core of a market-entry analysis.

How to claim treaty benefits: beneficial owner, LOB and PPT

The reduced rates are conditional, not automatic. Three gates stand between a payment and the treaty ceiling, and all three are written into the Agreement itself.

Gate one — beneficial ownership. Articles 10 to 13 grant the reduced rate only to the beneficial owner of the dividends, interest, royalties or service fees. A recipient that is a mere conduit — legally entitled to the income but obliged to pass it on — is not the beneficial owner, and the source state may apply its full domestic rate. This is the first question to document on any structure: who ultimately enjoys the income.

Gate two — the limitation-on-benefits (LOB) test of Article 28(2). A company resident in one state is not entitled to benefits in the other if, at the relevant time or for at least half the days of a 12-month period, non-resident (or otherwise non-eligible) persons hold — directly or indirectly — at least 50% of the company's shares. There are two escape hatches: the company qualifies anyway if (i) its principal class of shares is regularly traded on a recognised stock exchange, or (ii) it carries on a genuine economic activity in its state of residence (something more than merely holding securities or performing auxiliary or preparatory functions for related parties). A Polish holding created purely to route Brazilian income will struggle at this gate.

Gate three — the principal-purpose test (PPT) of Article 28(6). Even a structure that clears the LOB faces the general anti-abuse rule: a treaty benefit is denied if it is reasonable to conclude, given all the facts and circumstances, that obtaining it was one of the principal purposes of any arrangement or transaction that produced the benefit — unless granting it would accord with the object and purpose of the relevant provisions. The Agreement also contains a triangular rule (Article 28(3)) denying benefits on income attributed to a permanent establishment in a third state taxed at less than 75% of the residence-state tax, and a discretionary-relief mechanism (Article 28(4)) allowing a competent authority to grant a benefit it had denied where the taxpayer shows a non-abusive purpose.

Beyond these substantive gates lie the formal documentary requirements — chiefly a certificate of Polish (or Brazilian) tax residence, and, for certain contracts, registration or recording formalities. The verified treaty sources confirm the beneficial-owner and Article 28 conditions, but do not settle the exact formal paperwork or the implementing tax-authority instruction; those should be confirmed case by case at the date of the operation rather than assumed. Finally, Protocol §10 preserves each state's domestic anti-avoidance law — including thin-capitalisation and controlled-foreign-company (CFC) rules — so clearing the treaty gates does not switch off the source state's own defensive rules. This is where the firm's international tax planning team maps the structure against every gate before the first payment is made; the Brazilian side of the primary text can be read in full in Decree 12.865/2026.

What the treaty does not cover

A treaty ceiling is easy to over-read as a total tax cost. It is not. The Agreement covers only income tax and the CSLL in Brazil, and PIT and CIT in Poland (Article 2(2)) — and several material charges on a cross-border payment sit entirely outside that scope. Reading the treaty rate as the whole burden is the most common costing error on a Brazil–Poland flow.

CIDE. The Brazilian contribution for intervention in the economic domain (CIDE), at 10%, falls on the Brazilian payer of royalties (trademarks, know-how), technical services and management fees. It is a separate, autonomous levy the treaty does not reach, because the treaty covers only income tax and CSLL. So when the treaty caps the income tax on a software or know-how royalty at 10%, the 10% CIDE — where due — remains on top. CIDE does not apply to interest, JCP, dividends, capital gains, pure equipment rental, or licences of software without transfer of technology.

IOF on foreign exchange. Every outbound remittance settles a currency exchange that attracts IOF-câmbio. The exact rate in force per flow is unstable — it has been the subject of litigation (ADC 96 before the Supreme Court) and Legislative Decree 176/2025 — and moves within a documented band of roughly 0.38% to 3.5%. The treaty does nothing to it, and the applicable figure should be confirmed at the date of the operation.

Indirect and reform taxes. The treaty is an income-tax instrument; it has no bearing on Brazil's consumption taxes. On an import of services or goods into Brazil, the domestic indirect taxes continue to apply, and Brazil's tax reform is replacing the old ICMS/ISS/PIS/COFINS system with the new IBS and CBS. None of those is a covered tax under the treaty. A Polish group selling into or investing in Brazil must therefore run the income-tax treaty and the indirect-tax reform as two parallel work-streams — the treaty for withholding, the reform for consumption. That reform track is set out in the desk's Brazil tax reform for Polish companies page, the firm's tax reform practice, and the 2026 reform index. For software and SaaS flows specifically — where the 10% royalty ceiling, the CIDE carve-out and the reform's digital rules intersect — see the dedicated software and SaaS page. And on the goods side, the separately negotiated EU–Mercosur framework — which cuts Brazil's import duty but leaves internal taxes untouched — is covered in the EU–Mercosur export page.

Three worked examples: treaty ceiling versus domestic rate

The three examples below show the treaty doing three different things — leaving the rate untouched, capping it, and capping only part of the burden. Each is a payment from Brazil to Poland made in 2026 or later, so the treaty is in effect.

Example 1 — Dividend to a Polish parent (treaty does not reduce). A Brazilian operating company pays a R$ 1,000,000 dividend to its Polish parent, a company holding 100% of the capital for several years. From 1 January 2026, Brazil's domestic rate on outbound dividends is 10% flat (Law 15.270/2025) — where, until 2025, the dividend was exempt. The treaty ceiling under Article 10(2)(a) is 10% (the parent clears the ≥ 25%-for-365-days company test); the other-cases ceiling is 15%. Because the domestic 10% is at or below both ceilings, Brazil withholds 10% = R$ 100,000. The commercial headline of the desk sits in this example: the Polish shareholder moves from 0% to 10%, and the treaty does not neutralise the change — its ceiling is not below 10%. What the treaty guarantees here is certainty and a credit in Poland, not a lower Brazilian rate.

Example 2 — Technical service fee (treaty caps the income tax only). A Polish engineering firm invoices a Brazilian client R$ 500,000 for technical and consultancy services, with no permanent establishment in Brazil. The Brazilian domestic withholding would be 15%; Article 13(2) caps the income tax at 10%, so the IRRF is R$ 50,000 rather than R$ 75,000. But the autonomous CIDE at 10% (R$ 50,000) falls on the Brazilian payer and is untouched by the treaty. The combined income-tax-plus-CIDE load is therefore R$ 100,000 — of which only the R$ 50,000 IRRF was reduced by the treaty. Reading the 10% ceiling as the total cost would understate the burden by half.

Example 3 — Software royalty (treaty caps the rate). A Brazilian distributor pays a R$ 300,000 royalty to a Polish software owner. Software has no band of its own in Article 12, so it falls into the residual "all other cases" of Article 12(2)(b) at a 10% ceiling — below the 15% domestic rate. Brazil therefore withholds 10% = R$ 30,000 rather than R$ 45,000: here the treaty genuinely lowers the rate. CIDE turns on whether the licence involves a transfer of technology; a pure right-to-use software licence without technology transfer is exempt from CIDE, while a licence bundled with know-how is not — a case-by-case classification.

Across the three, the pattern is the discipline the desk applies to every flow: identify the article, read the band condition, compare the ceiling to the domestic rate, and remember the charges the treaty never touches. TaxUp's team advises Polish and Brazilian groups on exactly this mapping — matching each payment to its correct article, testing beneficial ownership and the Article 28 gates, and reconciling the treaty with domestic withholding, CIDE and the 2026 reform before the money moves.
