Reporting Under Instrução Normativa RFB nº 1.888/2019 FAQ

Instrução Normativa RFB nº 1.888/2019 is a regulation issued by the Receita Federal do Brasil (RFB) that requires cryptocurrency exchanges, as well as individuals and entities transacting with crypto assets, to report transaction details to the tax authority. The goal is to increase transparency and compliance in the Brazilian digital asset market.

As part of our operations in Brazil, which commenced 1 October 2025, we are legally required to comply with local regulations. In accordance with IN RFB nº 1.888/2019, we must report certain information on cryptocurrency transactions carried out by our Brazilian clients, or transactions involving crypto assets where one party is a Brazilian resident.

We are required to report information on:

• Buy and sell transactions of crypto assets.
• Transfers of crypto, both to and from Kraken (when involving Brazilian residents).
• Crypto-to-crypto exchanges (e.g., BTC to ETH).
• Deposits and withdrawals in fiat currency connected to crypto trades.

The reported data generally includes:

• Type of crypto asset (e.g., BTC, ETH).
• Date and type of transaction.
• Amount transacted (in crypto and BRL).
• Identification details of the client (e.g., CPF/CNPJ).

Exchanges are required to file monthly reports with the Receita Federal, covering all transactions that occurred during the prior month.

No. Your trading experience will not change. This is a tax regulatory reporting requirement and does not affect your access to our products and services.

Not directly. The reporting requirement ensures Receita Federal has visibility into your crypto activity. You remain responsible for correctly declaring your crypto transactions in your annual tax return (Declaração de Imposto de Renda).

We recommend consulting a qualified tax professional to ensure compliance with your obligations.

If you trade exclusively through Kraken, we will report your transactions as required. However, you may still have reporting obligations if you:

• Trade on foreign exchanges not registered in Brazil.
• Conduct peer-to-peer (P2P) transactions directly.
• Self-custody assets and transact outside of Kraken.

In these cases, you are personally responsible for reporting via the RFB system.

We are committed to protecting client data and only transmit the information required by law, using secure channels specified by Receita Federal. We do not share your data with third parties outside of legal or regulatory obligations.
