A Brazilian who moves to Dubai and does not file the Comunicação de Saída Definitiva do País stays a Brazilian tax resident for the first twelve consecutive months of absence, taxed on worldwide income including the Dubai salary. That is not an interpretation, it is the express wording of Article 2, item V of Normative Instruction SRF 208/2002 as amended in 2010.

The second surprise is the treaty. The Brazil to UAE convention treats an individual as a UAE resident only if they are domiciled in the UAE and are a UAE national, so a Brazilian in Dubai is outside it entirely and cannot use its tie-breaker or its reduced rates. This guide covers how residence actually ends, the two filings and their real deadlines, the nationality clause, the new 10 percent withholding on dividends remitted abroad from January 2026, what Brazil taxes a non-resident, and the offshore rules that stop applying once you are genuinely out.

How Brazilian Residence Ends, and the Twelve-Month Trap

Under Article 3, item II of IN SRF 208/2002 a person who leaves Brazil permanently becomes a non-resident on the date of departure. But Article 2, item V overrides that for anyone who leaves “without presenting the Comunicação de Saída Definitiva do País, referred to in Article 11-A, during the first 12 consecutive months of absence.” Miss the filing and you remain resident for a full year.

The wording of item V was rewritten by Normative Instruction RFB 1008 of 9 February 2010. Before that amendment the trigger was the annual Declaração; since 2010 it is the separate Comunicação, which is a different form with a different deadline. Guidance written before 2010, and a good deal written after it, still gets this wrong.

Article 3, item V closes the circle for someone who left on a temporary footing: they become a non-resident from the day after they complete twelve consecutive months of absence. Either way the twelve-month clock only matters because the Comunicação was not filed.

Your situation Date you become a non-resident
Left permanently and filed the Comunicação The date of departure, under Article 3, item II
Left permanently and did not file it The day after twelve consecutive months of absence, under Article 2, item V and Article 3, item V
Left on a temporary basis, stayed away more than twelve months The day after the twelfth consecutive month, under Article 3, item V

What is actually taxed during those twelve months

Article 11, paragraph 1 of the same instruction spells it out. Income from Brazilian sources is taxed exactly as it is for any other Brazilian resident, and income from foreign sources is taxed in Brazil under Articles 14 to 16, 19 and 20. In practice that means a Dubai salary in that window is taxable in Brazil through the carnê-leão, at rates reaching 27.5 percent, with no UAE tax to credit against it because the UAE levies none on employment income.

Paragraph 2 then switches the treatment: income received from the thirteenth consecutive month of absence is taxed exclusively at source or on a definitive basis under Articles 26 to 45. That is the line between filing a full annual return and simply having tax withheld.

The Two Filings and Their Real Deadlines

Article 11-A requires the Comunicação de Saída Definitiva do País from the date of departure up to the last day of February of the following calendar year. Article 11, item I separately requires the Declaração de Saída Definitiva do País by the last business day of April of the calendar year following the one in which non-residence is characterized. They are two filings, not one.

Paragraph 1 of Article 11-A states directly that the Comunicação does not dispense with the Declaração. Filing only the Comunicação leaves the final return outstanding; filing only the Declaração leaves you inside the twelve-month trap above.

Paragraph 2 is a detail that costs families money: dependants registered with a CPF who leave on the same date as the main filer must be listed on that person’s Comunicação. A spouse or child left off it is treated as having stayed.

Paying the tax, and the penalty for late filing

Article 11, item II requires the tax assessed in those returns, plus any other outstanding tax credits, to be paid in a single instalment by the deadline for the returns. Instalment plans that are available on an ordinary annual return are not available here, because the due dates of everything outstanding are brought forward to that date.

Article 13 sets the penalty for failing to file or filing late: where tax is due, 1 percent per month or fraction of a month on the tax due, with a floor of BRL 165.74 and a ceiling of 20 percent of the tax; where no tax is due, a flat BRL 165.74. The floor is small, which is precisely why people leave it and then find the residence consequence, not the fine, is what hurt them.

The public-sector exception that does not apply to most people

Article 12 keeps Brazilian residence for someone abroad in the service of Brazil in government agencies or offices. Its sole paragraph excludes employees of state-owned companies and mixed-economy companies posted abroad on a specific assignment for the company, and locally hired staff of diplomatic missions. An engineer seconded to the Gulf by a Brazilian state-controlled company is therefore treated like any other departing resident.

The Treaty’s Nationality Clause

Article 4(1)(b)(i) of the Brazil to UAE convention defines a resident of the UAE, for individuals, as “um indivíduo que tenha seu domicílio nos Emirados Árabes Unidos e que seja nacional dos Emirados Árabes Unidos”, which means an individual who has their domicile in the UAE and who is a national of the UAE. A Brazilian passport holder can never satisfy it.

The convention was signed in Brasília on 12 November 2018, approved by Legislative Decree 4 of 26 February 2021, entered into force on 15 March 2021 and was promulgated by Decree 10,705 of 26 May 2021. Under its Article 31 the withholding provisions applied to income paid, remitted or credited on or after 1 January 2022, and the other provisions to fiscal years beginning on or after that date.

Article 4(1)(a) defines the Brazilian side in the ordinary way, by liability to tax on the basis of domicile, residence, place of incorporation, place of management or any similar criterion. The asymmetry is deliberate, and it is the same shape Spain and Poland use, as our guide to the nationality clause in the Spanish treaty sets out.

The consequence is structural. Article 4(3) contains a full tie-breaker running from permanent home to center of vital interests, habitual abode and then nationality, but paragraph 3 only engages where a person is a resident of both states “by force of the provisions of paragraph 1.” A Brazilian in Dubai is a resident of one state under paragraph 1 at most, so the tie-breaker never starts. Whether Brazil still taxes you is decided entirely by IN SRF 208/2002.

What a UAE tax residency certificate can and cannot do here

A UAE tax residency certificate is genuine evidence that you live in the Emirates and is worth holding for banking and for other countries’ purposes. It cannot make you a treaty resident of the UAE under Article 4(1)(b)(i), because the missing element is Emirati nationality, not proof of domicile. Treat it as supporting evidence of where your life is, which is what Brazilian residence actually turns on.

Dividends Remitted Abroad: the 10 Percent That Started in 2026

Law 15,270 of 26 November 2025 inserted a new paragraph 4 into Article 10 of Law 9,249/1995: profits or dividends “pagos, creditados, entregues, empregados ou remetidos ao exterior” are subject to withholding income tax at 10 percent. Brazilian dividends paid to a non-resident stopped being exempt.

The same law introduced a parallel 10 percent withholding for residents, in Article 6-A of Law 9,250/1995, but only above BRL 50,000 paid by one company to one individual in a single month. The version that applies to remittances abroad has no such threshold in paragraph 4. A Brazilian company owner living in Dubai is exposed from the first real.

Paragraph 5 grandfathers profits relating to results determined up to calendar year 2025, provided the distribution was approved by 31 December 2025 and the amounts are due under company or civil law. Distributions approved in 2026 out of older profits do not automatically qualify, so the approval date in the corporate minutes is the fact that matters.

Article 10(2)(b) of the treaty caps dividend withholding at 15 percent for a beneficial owner resident in the other state, which is above the domestic 10 percent and therefore gives nothing. More to the point, a Brazilian in Dubai is not a resident of the other state under Article 4(1)(b)(i), so the cap is unavailable in either direction. This is one of the clearest places where the nationality clause has a cash consequence.

What Brazil Still Taxes Once You Are a Non-Resident

Becoming a non-resident removes worldwide taxation, not Brazilian-source taxation. Income arising in Brazil continues to be taxed at source under Articles 26 to 45 of IN SRF 208/2002, and the payer or your legal representative in Brazil is responsible for the withholding.

Brazilian income Position for a non-resident
Dividends from a Brazilian company 10 percent withheld at source on remittance abroad, under Article 10, paragraph 4 of Law 9,249/1995 as inserted by Law 15,270/2025
Rent from a Brazilian property Withheld at source; a legal representative in Brazil handles the collection and the monthly obligation
Sale of a Brazilian property or shares Capital gain taxed in Brazil, collected by the seller or their attorney at the time of the sale under Article 27 of IN SRF 208/2002
Your Dubai salary Outside Brazilian taxing rights once you are a non-resident, because it is neither Brazilian-source nor caught by worldwide taxation

The annual Declaração de Ajuste Anual stops as well. A non-resident who keeps filing one is asserting residence, and that assertion is exactly what the Receita Federal will rely on if it later disputes the departure date.

The Offshore Rules You Leave Behind

Law 14,754 of 12 December 2023 taxes profits of controlled entities abroad on 31 December each year, and applies by its own Article 1 to “renda auferida por pessoas físicas residentes no País”, meaning income earned by individuals resident in Brazil. A genuine non-resident in the UAE is outside its scope.

Article 5, paragraph 1 defines a controlled entity broadly: preponderance in corporate decisions or the power to appoint or remove most of the directors, or more than 50 percent of capital, profit rights or liquidation rights held directly or indirectly, alone or with related parties. Paragraph 2 treats each segregated class of shares or units as a separate entity, which catches a good deal of structuring.

For a Brazilian who holds a UAE free zone company, this is the practical payoff of getting the departure right. Filed correctly, the company’s profits sit outside the annual 31 December sweep. Left inside the twelve-month trap, they do not.

The treaty has its own anti-abuse response to UAE structures. Article 29 releases Brazil from granting treaty benefits where UAE law exempts offshore income of shipping, banking, financial, insurance, investment or headquarter-type companies, or taxes it at below 60 percent of the rate applied to comparable domestic activity. It is aimed at entities rather than individuals, but it is a reminder that the convention was drafted with UAE regimes in mind.

The Order to Do This In

The sequence matters more than any single step, because each filing has its own window and the twelve-month rule punishes a gap.

  • Keep dated evidence of the departure itself: the flight, the UAE entry stamp, the residence visa and the Emirates ID issue date.
  • File the Comunicação de Saída Definitiva do País from the date of departure and no later than the last day of February of the following calendar year, listing any CPF-registered dependants who left with you.
  • Appoint a legal representative in Brazil before you go if you will keep rent, dividends or a property, because the withholding obligations fall on someone in the country.
  • File the Declaração de Saída Definitiva do País by the last business day of April of the calendar year following characterization, and pay the assessed tax in a single instalment by the same date.
  • Tell your Brazilian banks and brokers that you are now a non-resident, so accounts are reclassified and withholding is applied correctly. Expect them to ask where you are tax resident, which is also what CRS reporting by UAE banks is built on.
  • Check the approval dates on any 2025 profit distributions before assuming the grandfathering in paragraph 5 of Law 15,270/2025 covers them.

If you are still weighing the move, our guide to what a tax-free UAE salary really means covers the home-country side more generally, and building a pension as a UAE expat deals with the gap that leaving a national system opens up.

What We Could Not Verify

Two points in this area could not be confirmed against a primary source at the time of writing and are deliberately left open rather than asserted.

The first is whether the United Arab Emirates currently appears in Normative Instruction RFB 1,037/2010, the list of jurisdictions with favored taxation and privileged tax regimes. Reporting indicates the UAE was removed from the favored-taxation list, and the consolidated text could not be retrieved to confirm the position as it stands today or whether any specific free zone regime remains listed. That listing, if it applied, would matter for the 25 percent rate on certain remittances, so confirm it with the Receita Federal before relying on a rate.

The second is the current reporting threshold for the Declaração de Capitais Brasileiros no Exterior to the Banco Central. The Banco Central site could not be read directly, and the threshold has been raised more than once. If you hold assets outside Brazil while still resident, check the current threshold and deadlines with the Banco Central rather than with secondary sources, which frequently quote superseded figures.

Frequently Asked Questions

Do Brazilians living in Dubai pay tax in Brazil?

Only on Brazilian-source income, and only once they are genuinely non-resident. Until the Comunicação de Saída Definitiva is filed, Article 2, item V of IN SRF 208/2002 keeps you resident for the first twelve consecutive months of absence, and Brazil taxes worldwide income in that window, including a Dubai salary.

What happens if I never filed the Comunicação de Saída Definitiva?

You were a Brazilian resident for those first twelve months and should have declared worldwide income for that period, becoming a non-resident from the day after the twelfth month under Article 3, item V. The filing penalty in Article 13 is modest, a minimum of BRL 165.74, but the unpaid tax on foreign income in that window is the real exposure.

Can I use the Brazil to UAE tax treaty as a Brazilian living in Dubai?

No. Article 4(1)(b)(i) defines a UAE resident individual as someone domiciled in the UAE who is also a UAE national, so a Brazilian passport holder is never a treaty resident of the UAE. The tie-breaker in Article 4(3) only applies to someone resident in both states under paragraph 1, so it never engages.

Are my Brazilian dividends still tax free if I live in the UAE?

No. Law 15,270 of 26 November 2025 added paragraph 4 to Article 10 of Law 9,249/1995, imposing 10 percent withholding on profits and dividends paid, credited, delivered, employed or remitted abroad, with no minimum amount. Profits from results up to 2025 can be exempt if the distribution was approved by 31 December 2025.

Does a UAE tax residency certificate stop Brazil taxing me?

Not by itself. It is useful evidence of where you live, but it cannot satisfy Article 4(1)(b)(i) of the treaty because that provision requires Emirati nationality. Your Brazilian position is decided by IN SRF 208/2002 and by whether you filed the departure communication on time.

What are the deadlines for the two departure filings?

The Comunicação de Saída Definitiva runs from the date of departure to the last day of February of the following calendar year, under Article 11-A. The Declaração de Saída Definitiva is due by the last business day of April of the calendar year following the one in which non-residence is characterized, under Article 11, item I, with the tax payable in a single instalment by the same date.

Do I still have to declare my UAE company to Brazil?

Not once you are a non-resident. Law 14,754/2023 applies by its Article 1 to individuals resident in Brazil, so its 31 December taxation of controlled foreign entity profits falls away. While you are still inside the twelve-month window, it applies to you in full.

Do I need someone in Brazil if I keep a property there?

In practice yes. Tax on Brazilian-source income of a non-resident is collected at source, and Article 27 of IN SRF 208/2002 contemplates collection by the seller or their attorney on a sale, so rent and disposals need a legal representative in Brazil to handle withholding and payment.

Should I keep filing the annual Brazilian tax return from Dubai?

No, and doing so is actively unhelpful. A non-resident is taxed exclusively at source under Article 11, paragraph 2 of IN SRF 208/2002, and continuing to file an annual adjustment return asserts residence that you may later need to disprove.
