The cheapest and most common way to buy crypto in Brazil is a PIX bank transfer into a domestic exchange — instant, 24/7 and the lowest-fee rail, with PIX-to-USDT on Mercado Bitcoin, Binance or Bitso as the standard route. The tax trap most buyers miss is that Receita Federal treats every crypto-to-crypto swap as a taxable disposal, so gains are taxable even if you never cash out to reais.
Legal status
Legal and regulated. BCB Resolutions 519/520/521 (Feb 2026) license VASPs; Law 14.478/2022 is the framework. Stablecoins are heavily used (80% of declared volume).
Exchanges you can use

| Mercado Bitcoin | regional | Brazilian | largest domestic exchange |
| Banxa | regional | on-ramp | PIX two-way |
KYC requirements
CPF (validated) + photo ID (RG, CIN, CNH, or passport) + residential address

FAQ
Is crypto legal in Brazil?
Yes, and regulated. BCB Resolutions 519/520/521 license VASPs from Feb 2026.
What is the crypto tax in Brazil?
Capital gains taxed 15–22.5%; exempt below R$35,000/month on domestic exchanges. Offshore exchanges have no exemption (flat 15%).
Which stablecoin is used in Brazil?
USDT dominates (88.7% of stablecoin volume), then USDC and the BRL-pegged BRZ.
What is DeCripto?
Brazil’s crypto-asset declaration (IN 2.291/2025), mandatory from July 2026, aligned with the OECD CARF standard.
What PIX limits apply when buying crypto in Brazil?
The BCB caps nighttime PIX transfers to a different individual at R$1,000 between 20:00 and 06:00, but an exchange deposit is not caught by that cap because the receiving exchange is a legal entity — the applicable ceiling is your bank’s TED-equivalent PIX limit (IN BCB 512/2024, updated by IN BCB 669/2025). You can raise your limits in your bank’s app, but under BCB rules the increase only takes effect after a waiting period of at least 24 hours.
Do I pay tax when I swap one crypto for another in Brazil?
Yes — Receita Federal treats a crypto-to-crypto swap as a disposal (alienação), so exchanging BTC for ETH or for a stablecoin is a taxable event valued at the BRL market rate on the swap date, even if you never convert back to reais. Each swap also counts toward the R$35,000 monthly sales total that determines whether the exemption applies.
Should I use a BCB-authorised exchange or an offshore one?
Brazil’s VASP regime (BCB Resolutions 519/520/521) took effect on 2 February 2026: domestic providers already operating had until 30 October 2026 to file for authorisation, and from that date BCB-authorised institutions are barred from dealing with unauthorised counterparties, so unlicensed platforms lose access to bank accounts, PIX and settlement. The reporting burden differs too — Brazilian exchanges file your trades with Receita automatically, while foreign-exchange, DEX and P2P volume above R$35,000/month must be self-declared monthly through DeCripto from 1 July 2026.
