One thing I still don't understand... should the profit only be declared when I withdraw the money from the exchange?

Crypto Alert: Federal Revenue Tightens the Noose on Pix Transactions on Exchanges

Hey guys, here's another piece of news from 2025 to brighten up Brazilians' day 🇧🇷.

Starting in 2025, the Federal Revenue Service will start receiving data on all Pix transactions made on cryptocurrency exchanges. Previously, the Revenue Service already monitored Pix transactions made by traditional banks, but now the inspection has been extended to payment institutions (such as digital banks and virtual wallets, used by most exchanges, such as Binance, Bitget and Mercado Bitcoin).

The Revenue Service will use the e-Financeira system to receive data on transactions over R$5,000 (individuals) and R$15,000 (companies) every six months, including Pix and other transactions. The goal is to combat tax evasion and follow international standards against tax evasion (such as the CRS).

In addition, the IRS already has information on cryptocurrency transactions made by Brazilians abroad and will begin to charge taxes on these assets from 2026, with the automatic exchange of information with other countries.
