Pay with Pix with no IOF charged by Peanut. Your balance stays in digital dollars. When you pay using a supported Pix QR code or send to a Pix key, the payment amount converts to reais. The all-in rate shown before you confirm is the full payment cost.
Adding money to the balance is a separate step and can involve its own conversion and costs. The wider IOF rules depend on the financial operation, as explained below.

What is IOF?
IOF is Brazil's federal tax on specified financial operations. Its rules cover credit, foreign exchange, insurance, and securities, among other categories. The updated Decreto 6.306/2007 sets out those categories and their rules.
For an international payment, first identify the operation: where the money comes from, where it goes, and how it is converted. A tax rate for one operation does not automatically apply to another.
Where does the 3.5% IOF rate apply?
Decreto 12.499/2025, dated June 11, 2025, changed several rates. Article 15-B of the updated rules includes 3.5% for specific foreign-exchange operations, such as:
- Buying foreign currency in cash.
- Settlements by cross-border payment issuers for customers' purchases or withdrawals abroad, subject to the applicable exceptions.
This is not a universal rate for international transfers or card transactions. Spending in Brazil with a card issued abroad is a different situation from buying goods abroad through a Brazilian payment issuer. Check the applicable operation in the current consolidated rules, rather than applying a travel headline to every payment.
What changed for stablecoins?
Stablecoins are digital assets referenced to a currency, such as the US dollar. Brazil's rules distinguish particular services involving these assets.
Resolução BCB 521/2025 brought specified virtual-asset services into the foreign-exchange framework from February 2, 2026. These include international payments and the purchase, sale or exchange of assets referenced to a currency.
Resolução BCB 561/2026 changed the rules for eFX, a regulated international payment or transfer service. From October 1, 2026, virtual assets cannot be used for the payment or receipt between an eFX provider and its foreign counterparty. That restriction concerns a specific part of the payment flow.
These two resolutions do not set a general IOF rate for stablecoins. The regulatory classification alone does not settle the tax treatment of a particular transaction. Likewise, PL 4.308/2024 is a legislative proposal, not an enacted tax rule.
How a Pix payment from Peanut is priced
Peanut does not charge IOF on Pix QR or key payments from your digital-dollar balance. The payment amount converts to reais at the all-in rate shown before confirmation. Review the recipient, the amount in reais and the amount deducted from your balance.
Adding money to your balance is a separate step. Depending on the funding route, it can involve its own conversion and costs. Read the Pix payment guide for the supported flow and Peanut's pricing for costs.
What to check before paying
Identify the transaction and any separate funding or conversion step. Check the current rule for that operation, then review the quote and keep the receipt. An app quote describes the payment cost; it does not determine every tax obligation you may have.
