Brazil tax residency for foreigners: the 183-day rule

A foreigner on a temporary visa becomes a Brazilian tax resident on the day they complete 184 days in Brazil, consecutive or not, within up to 12 months. Up to 183 days, Receita Federal treats you as non-resident. A permanent visa, or a temporary visa with a Brazilian employment contract, makes you resident from the day you arrive.

This page covers foreign nationals in general, with treaty notes for US and UK citizens. It explains who counts as resident, how the day count works, what you pay once resident, how the US and UK treaty situation affects you, and what to file when you leave. Ask a Brazilian accountant (contador) about your own case before you reach day 184.

Why tax residency matters

Tax residency decides whether Brazil taxes only your Brazilian income or your income from everywhere. A non-resident pays Brazilian tax only on Brazilian-source income, usually withheld at source. A resident must declare worldwide income and pay monthly tax on money received from abroad.

The switch can happen quietly. Remote workers, long-stay visitors and new residents often cross day 184 without noticing. Knowing your date lets you prepare a CPF, an accountant and a plan for your home country’s tax rules in advance.

Who is resident and who is not

Receita Federal’s “Residente e Não Residente” rules set the categories. The table lists the cases that apply to a foreigner arriving in Brazil.

Receita also lists a case for doctors in the Mais Médicos program on a temporary visa. They are resident from arrival.

The rules speak of visas (“visto”), and IN SRF 208/2002, articles 2 to 4, speak of visas and employment. Many residence permits today are granted inside Brazil as a residence authorization rather than a visa.

Check before you go: if your residence was granted inside Brazil, ask a Receita Federal unit or a contador how your permit is classified before you rely on the 184-day count. The safest assumption is that a permit with no end date works like a permanent visa and makes you resident from its start.

How the day count works

Every day you are in Brazil counts toward the 184, whether the days are consecutive or not.

The window is up to 12 months. If you do not reach 184 days within that window, a new period of up to 12 months starts from your next entry into Brazil.

Visitors should count their days as well. A visit can last up to 90 days, extendable by the Polícia Federal, with a maximum of 180 days per migration year (Decreto 9.199, article 20). The written rule names temporary-visa holders and not visa-exempt visitors. If you spend long stretches in Brazil as a visitor, plan as if the 184-day count applies to you, and ask a Receita Federal unit or a contador before you get close to it.

Keep your own record of entries and exits. Passport stamps, boarding passes and the Polícia Federal’s Certidão de Movimentos Migratórios all help if you ever need to prove your days.

What changes when you become resident

Residents pay carnê-leão on income from abroad and from individuals. Receita Federal defines it as the monthly income tax on income a resident individual receives from another individual or from abroad. Income already taxed at source, such as a Brazilian salary, is outside it.

The due date is the last business day of the month after you receive the income. You calculate it in Receita Federal’s online Carnê-Leão system, which generates a DARF payment slip.

Income from financial investments abroad, and profits or dividends from foreign companies you control, follow a separate rule. Lei 14.754 of December 12, 2023, article 2, has residents declare that income separately in the annual return (Declaração de Ajuste Anual), taxed at 15% with no deductions.

Residents also file the annual return. For the 2026 return (calendar year 2025), the filing period ran from 23 March to 29 May 2026. Filing was required above R$ 35,584 (about US$7,004, checked Oct 2026) of taxable income, or above R$ 200,000 (about US$39,370, checked Oct 2026) of exempt income. Receita Federal sets new thresholds and dates each year. Read its “Meu Imposto de Renda” pages when the 2027 rules appear early in the year.

Foreign-currency income is converted in two steps. First convert to US dollars at the rate fixed by the central bank of the paying country on the day you receive the money. Then convert to reais at the Banco Central buy rate for the dollar on the last business day of the first half of the month before receipt. Follow the method in Receita Federal’s Carnê-Leão manual when you file, since the online system applies it for you.

You need a CPF for all of this. See how to get a CPF in Brazil as a foreigner.

Income tax treaties: US and UK

A tax treaty decides which country taxes which income first, and how the other gives credit. Brazil’s treaties are listed on Receita Federal’s page of agreements to avoid double taxation, last updated July 8, 2026.

United States

There is no US–Brazil income tax treaty in force. The United States is not on Receita Federal’s list of agreements.

Brazil does recognize reciprocity with the US. Ato Declaratório SRF nº 28 of April 26, 2000 says US federal law allows a deduction for tax paid in Brazil. In return, Brazil lets residents offset income tax paid in the US against Brazilian income tax due. The reciprocity does not cover US state or local taxes.

The offset and its cap now sit in article 16 of IN SRF 208/2002, which replaced the older IN SRF 73/1998. You can offset the US tax in the month of payment, up to the extra Brazilian tax caused by the foreign income.

The US taxes its own citizens under its own rules, wherever they live. Before you claim a US credit in Brazil, or a Brazilian credit in the US, ask a tax adviser who handles both US and Brazilian returns.

United Kingdom

The UK–Brazil income tax treaty is signed but not in force.

• The UK–Brazil Double Taxation Convention was signed in Brazil on November 29, 2022. It has not yet entered into force.
• The UK made its side of the law in the Double Taxation Relief and International Tax Enforcement (Brazil) Order 2023 (SI 2023/839). The convention enters into force on the date of the later of the two countries’ notifications. That date will be published in the London, Edinburgh and Belfast Gazettes.
• Receita Federal’s list, updated July 8, 2026, does not include the United Kingdom.
• Brazil’s foreign ministry records the convention’s approval process as suspended, citing the treaty’s fiscal impact on Brazil (note dated September 28, 2026). No legislative decree or promulgation decree has been issued.

Without the convention, relief for UK tax runs through reciprocity. Receita Federal’s income tax guidance says tax paid on income received in Germany, the US and the UK can be offset in Brazil, within the offset limit.

The UK and Brazil have agreements in force on shipping and air transport (1967, supplemented in 2005) and on aircrew pay (2010, in force since February 21, 2017). They do not cover ordinary employment, freelance or investment income.

When the convention takes effect, Article 31(2) sets the start dates. In Brazil, it applies from January 1 after entry into force. In the UK, income tax and capital gains tax apply from the April 6 tax year after entry into force. As of October 18, 2026, the convention is still not in force.

Other countries

Canada and Portugal appear on Receita Federal’s list. Australia does not. On December 13, 2023, Australia said it would look to negotiate its first tax treaty with Brazil.

When you leave Brazil

Leaving as a resident has two separate filings.

1. Comunicação de Saída Definitiva do País (CSDP). This notice tells Receita Federal you left permanently or became non-resident. File it online by the last day of February of the year after you leave. It is free.
2. Declaração de Saída Definitiva do País (DSDP). This is the departure tax return. File it the year after you leave, by the income tax return deadline, and pay any tax due in a single installment. The DSDP is required whether or not you filed the CSDP.

Also notify any Brazilian payment source, such as a tenant or employer, so it can withhold income tax on what it pays you after you leave.

You become non-resident from the date you leave permanently. If you leave temporarily, you become non-resident the day after you complete 12 consecutive months abroad. A Brazilian who returns to live in Brazil becomes resident again on arrival. A foreigner who comes back falls under the visa rules in the table above.

Common mistakes

Most problems come from late action, not from the rules themselves.

• Missing the switch date. Carnê-leão is due from the month after you become resident. Late payment brings interest and fines.
• Forgetting foreign investments. Interest, dividends and gains abroad belong in the annual return under Lei 14.754/2023.
• Leaving without filing. Without the CSDP and DSDP, Receita may still treat you as resident.
• Assuming a treaty exists. Neither the US nor the UK has an income tax treaty in force with Brazil.

Before day 184

1. Count every day in Brazil from your first entry.
2. Note the date you will reach day 184 in your 12-month window.
3. Get a CPF before that date.
4. Book a Brazilian accountant to review your income sources.
5. Ask an adviser in your home country how it treats the same income.
6. Learn the carnê-leão due date: the last business day of the month after you are paid.
7. Before you leave for good, diary the CSDP deadline (last day of February) and the DSDP deadline.
