US Expat Taxes in Brazil: How to File and Avoid Double Tax

Americans who move to Brazil for work, family, or retirement quickly discover that two governments are tracking their income: the Receita Federal do Brasil and the IRS back home. US expat taxes in Brazil come with an unusual wrinkle, because there is no comprehensive US-Brazil income tax treaty, even though the two countries have coordinated social security through a totalization agreement since 2018. Because Brazil taxes its residents on worldwide income and the United States taxes its citizens and green card holders no matter where they live, an American living in Brazil typically owes a filing obligation in both countries every year, and without a treaty to lean on, the entire double-tax planning exercise rests on the Foreign Tax Credit and the Foreign Earned Income Exclusion.

Do US Citizens Living in Brazil Have to File Both Brazilian and US Tax Returns?

Yes, in almost every case. Brazil taxes individuals who qualify as tax residents, generally meaning they hold a permanent visa, work under a local employment contract, or meet the country's time-based residency test, on their worldwide income through the Receita Federal do Brasil. The United States separately taxes its citizens and green card holders on worldwide income no matter where they live, a rule tied to US citizenship or immigration status rather than Brazilian residency.

That means the two filing obligations run independently, and unlike in many other countries, there is no income tax treaty sitting between them to coordinate the relief. Filing and paying tax in Brazil does not excuse you from filing a US Form 1040, and filing a US return does not excuse you from your Brazilian obligations. The Foreign Earned Income Exclusion and the Foreign Tax Credit do all of the double-tax planning work on the US side because no treaty exists to share the load.

How Does Brazil Tax Residents on Worldwide Income?

Brazil applies its individual income tax on a worldwide basis to anyone who qualifies as a tax resident, using progressive rates that apply as income rises, and that is the starting point for figuring out what an American in Brazil actually owes there before turning to the US return. Employers generally withhold tax directly from Brazilian payroll throughout the year, similar to US wage withholding.

Foreign-source income, including US wages, self-employment income, or investment income with no Brazilian withholding agent, is generally reported and paid monthly through a self-assessment mechanism known as the carne-leao, rather than waiting for the annual filing season. Every resident then reconciles the year on an annual adjustment return filed with the Receita Federal do Brasil, typically due in the spring following the tax year. The current-year rates and carne-leao mechanics should always be confirmed, since Brazilian tax rules are updated periodically and a stale figure can throw off both the Brazilian calculation and the US Foreign Tax Credit that depends on it.

Should You Claim the FEIE or the Foreign Tax Credit on Brazilian Income?

For Americans earning income in Brazil, the choice between the Foreign Tax Credit and the Foreign Earned Income Exclusion is less automatic than it is in higher-tax countries, because Brazilian income tax does not consistently run higher than the comparable US rate the way it does across much of Western Europe. That makes a year-by-year comparison worthwhile rather than defaulting to one election.

The Foreign Tax Credit on Form 1116 credits Brazilian income tax paid, computed by category under IRC Sections 901 and 904, dollar for dollar against US tax, and unused credit carries back one year and forward ten years on Schedule B. The Foreign Earned Income Exclusion on Form 2555 instead excludes foreign earned income up to an annually indexed maximum, for example $130,000 for 2025, under IRC Section 911. The FEIE does nothing for self-employment tax, can disqualify the refundable Additional Child Tax Credit for a family with kids, and once revoked generally cannot be re-elected for five years without IRS consent, so the Foreign Tax Credit is often the more durable choice for higher Brazilian earners even without a treaty pushing income toward the credit automatically. Our FEIE versus Foreign Tax Credit comparison walks through the decision in more detail.

What Does the US-Brazil Tax Treaty Do for Double Taxation?

Nothing, because no such treaty exists. The United States and Brazil have discussed a comprehensive income tax treaty for decades, but none has ever been signed and ratified, which puts Brazil in a different position than most major US expat destinations. For Americans in Brazil, this means the saving clause debates, tie-breaker residency rules, and treaty-based pension provisions that shape planning in treaty countries simply are not available here.

Instead, double-tax relief for a US person in Brazil rests entirely on domestic law: the Foreign Tax Credit under IRC Sections 901 and 904, and the Foreign Earned Income Exclusion under IRC Section 911. As a matter of domestic law and administrative practice, both countries generally allow a credit for income tax paid to the other, so Brazilian income tax is generally creditable on Form 1116 even without a treaty specifying it. That practical result should not be confused with treaty protection, since without a treaty there is no tie-breaker for dual residency and no treaty article to fall back on for an issue the Internal Revenue Code does not otherwise address.

Does the US-Brazil Totalization Agreement Cover Social Security?

Yes, and this is where Brazil runs the opposite direction from the treaty picture. A totalization agreement between the United States and Brazil has been in force since October 1, 2018, stopping a worker from paying into both countries' social security systems on the same earnings at the same time, even though the two countries still have no income tax treaty. Without it, an American employee or self-employed person working in Brazil could owe both Brazilian social security contributions and US self-employment tax on the identical income.

The agreement assigns coverage to a single system based on where the work is performed and how long the assignment is expected to last, documented with a certificate of coverage issued by the Social Security Administration or by Brazil's INSS, depending on the direction of the assignment. Self-employed Americans in Brazil should not assume US self-employment tax automatically applies; our guide to totalization agreements and self-employment tax abroad covers the certificate process.

How Are Brazilian Pensions and Retirement Accounts Taxed by the US?

Not automatically, and the lack of a US-Brazil tax treaty makes the analysis more clear-cut than it is in countries where treaty language can defer US tax on a foreign plan. Brazil's mandatory INSS pension and private supplementary vehicles such as PGBL and VGBL plans are not, by themselves, tax-deferred for US purposes just because they receive favorable treatment under Brazilian law.

The general US rule, under IRC Sections 401(a) and 402(b), is that income accruing inside a foreign retirement arrangement is taxed currently to a US person unless a specific treaty provision defers it. Because no US-Brazil treaty exists, that exception is not on the table for a Brazilian plan, so each plan has to be analyzed under the general default rule. Our foreign pension US tax treatment guide walks through the four questions that determine the answer for any foreign plan: whether growth is taxed as it accrues, whether a treaty defers it, what has to be reported, and how distributions are taxed.

Are Brazilian Investment Funds Taxed as PFICs?

Usually, yes, and this is one of the more expensive surprises for Americans investing through a Brazilian brokerage. A Brazilian fundo de investimento, whether a fixed-income fund, a multimercado fund, or an equity fund, typically meets the definition of a passive foreign investment company under IRC Section 1297, with Sections 1291 and 1298 governing the tax treatment. That classification is a matter of US tax law, does not turn on how the fund is taxed inside Brazil, and applies whether or not a tax treaty exists.

Once a fund is a PFIC, the default US tax treatment is punitive: absent a timely election, gains and certain distributions are spread over your holding period, taxed at the highest rate in effect for each of those years, and hit with an interest charge on top. Each PFIC generally requires its own Form 8621 filing, even in a year where no tax is actually due, which is why Americans in Brazil are usually steered toward US-domiciled brokerage accounts and US-based index funds rather than a local fundo through a Brazilian bank.

What Else Do You Have to Report to the IRS?

Beyond the income tax return itself, Brazilian financial accounts and investments carry their own reporting obligations that apply whether or not any US tax is owed, and none of them depend on a tax treaty. These filings are enforced on their own terms, and the penalties for missing them are typically far larger than any tax that would have been due.

Whether you even count as a US tax resident in the first place, if your situation is more complicated than straightforward citizenship, such as a long visit on a work visa before a move became permanent, is a separate question governed by the substantial presence test.

Bottom Line

Living in Brazil does not simplify your US tax picture, and the missing income tax treaty means there is no treaty layer to fall back on the way there is in many other expat destinations. The Receita Federal do Brasil and the IRS operate entirely independently, and the Foreign Tax Credit and the Foreign Earned Income Exclusion have to do all of the double-tax work on their own. The totalization agreement in force since October 1, 2018 still coordinates social security despite the missing treaty, but pensions, investment funds, and foreign accounts each carry their own reporting rules on top of the income tax analysis, and getting any one of them wrong tends to cost more in penalties than the underlying tax ever would have.
