Multi-Currency Strategy for Brazilians: Taxes, IOF and CBE

Residents of Brazil may hold money in several currencies, as long as an authorized institution handles the exchange. What matters is tax and reporting: Law No. 14,754/2023 (Lei 14.754/2023) taxes income abroad at 15%, including exchange-rate variation on redemption or sale, and the CBE applies from US$ 1,000,000.

This guide explains the Brazilian rules that apply to anyone holding assets in more than one currency: the foreign exchange framework, taxation of exchange-rate variation, IOF (the financial transactions tax) and reporting to the Central Bank. It does not offer exchange-rate forecasts or recommended allocation percentages across currencies. No official source supports that kind of number, and an investment decision depends on your profile and your financial advisor.

Can a Brazil resident hold money in several currencies?

Yes. Law No. 14,286/2021 (Lei 14.286/2021) says that transactions in the foreign exchange market may be carried out freely, with no limit on value, subject to the legislation, the guidelines of the National Monetary Council and the regulations of the Central Bank of Brazil (art. 2). The exchange rate is freely agreed between authorized institutions and their clients (art. 2, sole paragraph).

Three rules of the same law define the "how":

• •Foreign exchange transactions may only be carried out by institutions authorized by the Central Bank (art. 3).
• •The entry and exit of national or foreign currency from the country must go through an authorized institution, which identifies the sender and the recipient (art. 14).
• •Carrying cash outside that channel is allowed only up to US$ 10,000 or the equivalent in other currencies, or when the entry or exit is documented as set out in the regulations (art. 14, §1). Noncompliance may lead to forfeiture of the excess amount (art. 14, §3).

The Central Bank may also require information from residents to compile official statistics (art. 11), and that is where the obligation to report capital abroad comes from, covered below.

How is exchange-rate variation taxed on investments abroad?

For individuals who live in Brazil, Law 14,754/2023 treats financial investments abroad as a category of their own. The income goes on the Annual Adjustment Return (DAA), separate from other income, and pays 15% on the annual portion, with no deduction from the base (art. 2, §1). The concept of income includes, by way of example, the exchange-rate variation of the foreign currency, in addition to interest, premiums, dividends and gains in the secondary market (art. 3, §1, II).

Conversion to reais uses the closing rate of the foreign currency published, for sale, by the Central Bank on the date of the taxable event, unless the law provides otherwise (art. 15). Assets and rights abroad that are not financial investments, such as real estate, follow the capital gains rules of art. 21 of Law 8,981/1995 (Law 14,754, art. 2, §2).

Can I offset losses and deduct tax paid abroad?

Partly, and within limits set by law:

1. •Losses: realized losses on financial investments abroad, supported by proper and valid documentation, offset income from investments abroad in the same period. The excess can offset profits and dividends of controlled entities abroad computed on the DAA for the same period, and what remains can be offset in later periods, only once (art. 9).
2. •Tax paid abroad: it can be deducted from the IRPF owed if there is a provision for offsetting in a double taxation treaty or reciprocity of treatment (art. 4). The deduction cannot exceed the difference between the IRPF with and without that income, it does not apply to tax that can be reimbursed, and the excess is not carried to other years (art. 4, §§ 1, 3 and 4).

Conversion of the tax paid abroad uses the Central Bank buying rate on the day of payment (art. 4, §2).

Does IOF apply when I convert reais into another currency?

The foreign exchange IOF is in the IOF Regulation (Decree 6,306/2007), whose art. 15-B sets the rates according to the type of transaction. This guide does not state a percentage for a concrete reason: in the compiled text on the Planalto website, art. 15-B appears with successive wordings, given by Decrees 12,466 and 12,499 of 2025, one of them marked as suspended by Legislative Decree 176/2025, with a reference to ADC 96.

Before any transfer, confirm the rate in force for your type of transaction in the compiled Decree 6,306/2007 and with the institution that will carry out the exchange. This cost belongs in the math of any diversification, but the figure should not be copied from a generic guide.

Does the CBE take all my currencies into account?

BCB Resolution 279/2022 defines Brazilian capital abroad as amounts, goods, rights and assets of any nature held outside the country by residents (art. 1). The information to be reported covers, among other things, deposits at nonresident institutions, shares of funds abroad, debt securities of nonresidents, real estate abroad, virtual assets and derivatives (art. 7).

The threshold is in dollars "or its equivalent in other currencies" (art. 10), which matters for anyone who splits their assets among euros, Swiss francs and others:

Deadlines, fines and the step-by-step are on the Central Bank's CBE page. The text of the resolution has no exchange-rate rule for adding up different currencies; confirm this point on the Central Bank's website before filing.

What about stablecoins and other virtual assets?

Law 14,754 includes virtual assets and digital wallets among financial investments abroad and places the variation of the cryptocurrency against the national currency among the income (art. 3, §1). It also says that the classification of virtual assets and digital wallets will be set out in regulations from the Federal Revenue Service (art. 3, §3). BCB Resolution 279 lists virtual assets among the items to be reported (art. 7).

If part of your dollar reserve is in a stablecoin, the classification question is one for your accountant: confirm the Federal Revenue Service regulations in force before assuming the same treatment as a bank deposit.

In what order should you build a multi-currency strategy within the law?

1. •Map where the assets are and in which currency, by institution and by type: non-interest-bearing account, interest-bearing deposit, fund, virtual asset, equity stake.
2. •Separate the tax treatment of each type, using the Law 14,754 table above.
3. •Calculate the IOF of the transaction using the text in force and with the exchange institution.
4. •Build the calendar: the DAA and, if you reach the threshold, the annual CBE. The offshore banking service helps organize accounts and statements.
5. •If there is a company abroad, see how Law 14,754 treats the controlled entity in the offshore dropshipping guide and the controlled foreign company rules worldwide.
6. •Validate with your accountant through tax planning and compliance.
