Moving money from Brazil to close on a US property involves a tax most buyers budget wrong, because its rate is currently contested and its application to property purchases is not settled. The difference between the two rates in circulation is material: on a typical down payment it is roughly R$ 14,000. This article does not tell you which rate applies. It tells you what to confirm, and why the answer changes your number.
What is established
Brazilian outbound currency operations carry IOF, a federal tax on financial operations. The rate depends on how the operation is classified, and the classification depends on the stated purpose and the way the exchange contract is written.
Two rates circulate in current guidance. Remittances classified as the sender's own investment abroad are generally cited at 1.1%. Other individual remittances are generally cited at 3.5%.
What is not settled, as of October 2026
Three things, and a buyer should know all three.
The rate itself is under dispute. The increase introduced by Decreto 12.499/2025 was overturned in Congress and then addressed by an injunction at the Supreme Federal Court. Published summaries disagree on what is currently in force.
The classification of a property purchase is not defined in the public guidance. No source consulted states whether acquiring real estate abroad falls under investment (the lower rate) or general remittance (the higher one). It likely turns on the declared purpose and the contract form.
Guidance online is inconsistent. Several widely circulated calculators cite superseded decrees. A figure found on a blog is not a rate you can budget against.
A rate published here would be acted on. Where the applicable rate is genuinely contested and the classification of this specific use is undefined in public guidance, the responsible answer is the question to ask, not a figure to trust. Confirm with your bank or exchange broker and with a Brazilian tax adviser, in writing, before contracting.
Why the difference is worth the phone call
Take a US$ 350,000 property financed with 30% down. The amount crossing the exchange is US$ 105,000. At R$ 5.60, that is R$ 588,000.
At 1.1%, the IOF is about R$ 6,500. At 3.5%, about R$ 20,600. The difference is roughly R$ 14,100 on a single transfer — more than most buyers budget for closing costs in total.
This is also a direct argument for financing rather than paying cash. A cash purchase moves US$ 350,000 across the exchange instead of US$ 105,000, and whatever rate applies, it applies to the larger number.
The four questions to put to your bank, in writing
- Under which classification will you process this operation, and what IOF rate does that carry today?
- What documentation do you require to support the declared purpose — purchase contract, closing statement, proof of the US account?
- What is the spread between your quoted rate and the commercial rate? On a six-figure transfer, the spread frequently exceeds the tax.
- What reporting obligation does this create for me — annual declaration of assets held abroad, and at what threshold?
Ask these before contracting the exchange, not after. The classification is decided when the contract is written.
What this does not cover
Declaring the asset once you own it is a separate obligation from moving the money, with its own thresholds and deadlines on the Brazilian side, and separate US obligations on the other. Neither is addressed here.

General information as of October 2026, not tax or legal advice. The applicable IOF rate was contested at the time of writing. Confirm current rates and classification with your bank and a Brazilian tax adviser before contracting an exchange operation.
