Do Americans Pay Tax Twice in Brazil? The 2026 Rules

EXPATS · TAXES · 2026

Americans living in Brazil do not usually pay full tax twice, but they do have to file in both countries and navigate the rules carefully. The key tools are the Foreign Earned Income Exclusion and the Foreign Tax Credit, because there is no US–Brazil tax treaty to fall back on.

You never stop filing US taxes

The first thing to understand is that the United States taxes its citizens on worldwide income no matter where they live. Moving to Rio or São Paulo does not end your obligation to file a US federal return each year.

Most expats who plan properly owe little or no extra US tax, but the filing itself is mandatory. Skipping it, even in a year you owe nothing, can create penalties later on.

The Foreign Earned Income Exclusion

The biggest tool is the Foreign Earned Income Exclusion. For the 2026 tax year it lets a qualifying American exclude up to US$132,900 of foreign earned income from US tax, claimed on Form 2555.

To qualify you pass either the physical-presence test (330 days abroad in a 12-month period) or the bona-fide-residence test. The exclusion covers earned income such as salary, not passive income like dividends or rent.

FBAR: reporting your Brazilian accounts

Separate from income tax, the FBAR requires you to report foreign financial accounts to the US Treasury if their combined value tops US$10,000 at any point in the year. It is an information form, not a tax.

It catches more people than expected, because the threshold is an aggregate across all accounts. A Brazilian checking account, a savings account and a brokerage can cross it together even if none is large on its own.

FATCA and Form 8938

FATCA adds a second reporting layer. A single American abroad files Form 8938 with their return once foreign financial assets exceed US$200,000 at year-end, with higher thresholds for couples and for balances during the year.

FBAR and FATCA overlap but are different forms, and you may need both. Neither adds tax by itself, but the penalties for failing to file are steep, which is why they matter so much.

There is no US–Brazil tax treaty

Here is the catch that surprises people: the United States and Brazil have no comprehensive income tax treaty. Many countries have one to prevent double taxation, but the US–Brazil relationship relies on credits instead.

The two countries do have a Social Security Totalization Agreement, in force since 2018, which coordinates retirement contributions. But for income tax you lean on the Foreign Tax Credit, not a treaty.

The Foreign Tax Credit

The Foreign Tax Credit is the main shield against paying twice. Income tax you pay to Brazil can generally be credited against the US tax due on that same income, claimed on Form 1116.

Because Brazil’s rates on residents can exceed US rates on the same income, many Americans in Brazil end up with credits to spare. The exclusion and the credit are often combined, with care not to double-count the same income.

What Brazil expects from you

On the Brazilian side, once you become a tax resident — broadly, after enough time in the country or on a permanent visa — Brazil taxes your worldwide income. Income not taxed at source is reported through the Carnê-Leão system, at rates up to 27.5%.

So a long-stay American often files in both countries: a US return using the exclusion and the credit, and a Brazilian return on worldwide income. Coordinating the two is where a cross-border accountant earns the fee.

A note for freelancers

Self-employed Americans face one extra wrinkle: the exclusion removes income tax but not US self-employment tax. Thanks to the totalization agreement, those who pay into Brazil’s system can often avoid paying US self-employment tax on the same earnings.

That makes the 2018 agreement more valuable than it first looks for remote workers and contractors. Confirm your status, because it decides which country’s social contributions you owe.

Practical steps

Keep clean records of income, Brazilian tax paid and account balances, since both the FBAR and the Foreign Tax Credit depend on them. File on time even in years you owe nothing, to preserve the exclusion and avoid penalties.

This is general information, not tax advice. The absence of a treaty makes US–Brazil cases genuinely tricky, so anyone with meaningful income or assets should work with an accountant who handles both systems.

State taxes do not disappear either

One trap catches Americans from high-tax states. Some states, notably California, keep treating you as a resident for tax until you formally cut ties, so moving to Brazil does not automatically end a state filing obligation.

Severing state residency means closing the obvious links — a home, a driver’s license, voter registration — before you leave. It is worth checking your former state’s rules, because a forgotten state return can undo careful federal planning.

When to bring in a professional

Simple cases — a salaried American comfortably under the exclusion, with one or two Brazilian accounts — are manageable with good software and care. The complexity rises fast with self-employment, investments, property or a Brazilian business.

Because there is no treaty to lean on, a cross-border accountant who knows both systems usually pays for themselves in avoided penalties and missed credits. Treat the first year’s return as the one to get professional eyes on.
