If you're holding crypto in Brazil, you need to know the tax game or you'll get caught off guard. Let me break down what the Federal Revenue actually requires from you.

First, the annual declaration. If your crypto assets hit BRL 5,000 or more by December 31, you're filing an IRPF (Individual Income Tax Return). There's no way around it. When you're filling out the Assets and Rights section, you go to Group 08 for cryptoassets and pick your code - Bitcoin is 01, Ethereum is 02, other altcoins are 03, NFTs are 10. You need to list what you own, how much it's worth in reais, where it's stored (exchange name with CNPJ or your own wallet), and the acquisition cost. Pretty straightforward.

Now here's where crypto taxes in Brazil get interesting - and where most people mess up. Capital gains aren't taxed annually. They're taxed monthly, but only if you cross a threshold. If your total sales in a month stay under R$ 35,000, you're exempt. That's the sweet spot. But the moment you sell above that? The profit gets hit with tax ranging from 15% to 22.5% depending on the amount. You calculate it using the Federal Revenue's GCAP program and pay via DARF by the last business day of the following month.

There's also the reporting side. Brazilian exchanges have to automatically report your movements to the Federal Revenue through Instruction Normative 1888. But if you're trading on foreign exchanges or doing peer-to-peer deals, you're responsible for reporting if your monthly operations exceed R$ 30,000. The new DeCripto rules (IN 2291/2025) are tightening this up even more to match OECD standards.

The bottom line for crypto taxes in Brazil? Keep meticulous records. Date, amount, quantity, cost basis, which exchange - everything. The Federal Revenue knows more than you think, and they're getting better at tracking crypto transactions. The fines for not complying aren't worth the risk. Whether you're trading Bitcoin, Ethereum, or anything else, the compliance framework is the same, and it's getting stricter.
