How to Invest in US ETFs from Brazil Through an International Broker

Brazil is a small slice of the global market - a few percent of world market capitalization. Keeping every real in Ibovespa stocks and Tesouro Direto means your wealth rises and falls with one economy and one currency. A US-listed ETF that tracks an index like the S&P 500 gives you a stake in hundreds of large American companies in a single trade, which is a fast way to add diversification and exposure to the dollar. It also introduces currency risk that cuts both ways: a stronger dollar lifts your returns in reais, a stronger real trims them.

Buying the US-listed fund directly, rather than a local proxy, gets you two concrete things. The first is choice: the US market lists well over two thousand ETFs, against a few dozen internationally focused ones you would find at home. The second is cost - the original funds carry some of the lowest management fees anywhere, often around 0.03% a year for a big S&P 500 tracker. Those two advantages are the whole reason to deal with an international account instead of staying put.

Opening an account abroad is the first real step, and Brazilians have a handful of well-trodden options. Avenue, Nomad and Inter Conta Global are built for the Brazilian retail investor - the apps are in Portuguese, support understands the tax questions, and opening an account takes minutes with your CPF and a document photo. Interactive Brokers is the more advanced, globally used platform, with a wider instrument range and generally lower FX costs, but a steeper learning curve.

What to compare between them is not the headline brokerage - most charge zero commission on US ETFs - but the cost of getting your money across the border. Look at the currency spread each one applies when it converts your reais, whether it charges an account or inactivity fee, and how withdrawals back to Brazil are priced. For a beginner making regular contributions, the FX spread is the number that quietly matters most over time.

The main cost of investing directly shows up when you send money abroad, not when you trade. Each remittance pays a currency spread plus IOF (the tax on foreign-exchange operations), which together commonly run somewhere between 1.2% and 1.8% of the amount you transfer. That is a one-time hit on each deposit rather than an annual fee, so it weighs much more heavily on someone moving small amounts every month than on someone sending a larger lump sum a few times a year.

For assets held directly abroad, Law 14,754/2023 rewrote the rules, and they now apply in full. Gains and income from foreign financial investments - including ETFs - are taxed at a single flat rate of 15%, calculated once a year inside your annual tax return (the Declaração de Ajuste Anual), not month by month.

Two consequences matter for beginners. First, the old monthly carnê-leão and GCAP filings no longer apply to these investments - the tax is settled annually in the return. Second, the old exemption for monthly sales up to R$35,000 is gone for foreign brokerage accounts, so it no longer shields small sales made abroad. On the upside, you can now offset losses against gains within the regime. Dividends paid by US companies are generally withheld at 30% at source in the US, and Brazil's reciprocity treatment with the US lets you avoid being taxed twice on the same income.

None of this is a reason to be scared off, but it is a reason to keep good records from day one. Because the tax is calculated on your gain in reais, you need the exchange rate at the moment you bought and the moment you sell - not just the dollar prices. Get that habit right early and the annual return becomes bookkeeping rather than a scramble.

Buying US ETFs directly makes the most sense when you value the full range of American funds, the lowest possible management fees, and having your capital held in dollars outside Brazil. The costs to weigh against that are the per-remittance FX toll and the yearly foreign-income calculation on your tax return - both manageable, especially if you contribute in larger, less frequent transfers and keep clean records. Whatever you decide, no investment is risk-free, and your returns depend on both the market and the exchange rate, so size the position to your own risk tolerance.
