Brazilian Cryptocurrency Tax Treatment: 17.5% Flat Rate Explained
Brazilian Crypto Tax Calculator
How the Tax Works
Brazil's tax authority (Receita Federal do Brasil) taxes all cryptocurrency gains at a flat 17.5% rate starting June 12, 2025. There are no exemptions for small gains or long-term holdings. Even crypto-to-crypto trades are taxable events. This calculator helps you determine your tax liability based on Brazil's unique FIFO (First-In, First-Out) method for cost basis calculation.

Why This Matters in Brazil
Step 1: Calculate Capital Gain
Capital Gain = Sale Price - Purchase Price
Step 2: Calculate Tax
Tax = Capital Gain Ă 17.5%
Step 3: FIFO Method
If you bought the same asset multiple times, the RFB uses First-In, First-Out method to determine your cost basis. This means the first coins you purchased are the first ones sold when calculating your gain.
Before June 2025, Brazil was one of the few countries where you could trade crypto without paying taxes on small gains. Now, thatâs over. Starting June 12, 2025, every profit you make from selling, trading, or earning crypto in Brazil is taxed at a flat 17.5% - no exceptions, no exemptions, no loopholes. Whether you bought Bitcoin for $1,000 and sold it for $1,500 last week, or swapped Ethereum for Solana yesterday, the tax man wants his cut. And if you didnât track those transactions? Youâre already behind.
Whatâs Actually Taxed Now?
The Brazilian tax authority, Receita Federal do Brasil (RFB), doesnât care if you held your crypto for one day or one year. It doesnât matter if you made $50 or $50,000. Every single capital gain is taxed at 17.5%. That includes:
- Selling crypto for Brazilian reais (BRL)
- Trading one crypto for another (like BTC to ETH)
- Earning staking rewards or mining income
- Receiving crypto as payment for goods or services
- DeFi yield farming, liquidity provision, or airdrops
Even if you never cashed out to BRL, trading crypto-to-crypto counts as a taxable event. Thatâs a big shift. In many countries, swapping tokens is treated like a barter - not a sale. Not in Brazil. The RFB sees it as a disposal, plain and simple.
When Do You Need to Report?
If your total crypto transactions in a month exceed BRL 5,000 (roughly $950 USD), you must report them. Thatâs not a threshold for paying tax - itâs a threshold for reporting. Even if you lost money, you still have to file. The deadline is April 30 of the following year. For the 2025 tax year, thatâs April 30, 2026.
You file through eCac, the RFBâs online portal. But hereâs the catch: eCac wasnât built for crypto. Thereâs no âcrypto gainsâ field. You have to manually enter each transaction, calculate profits, and categorize them under âother income.â Many users report the system crashes when uploading large CSVs from exchanges. No official guidance exists on how to handle complex DeFi transactions. Youâre on your own.
How the Tax Is Calculated
The math is simple, but the record-keeping isnât.
Letâs say you bought 0.5 BTC for BRL 25,000 in March 2024. In May 2025, you sell it for BRL 40,000. Your profit? BRL 15,000. Your tax? 17.5% of that = BRL 2,625.
But what if you bought 0.1 BTC on January 15 for BRL 5,000, then another 0.1 BTC on February 10 for BRL 5,500, and sold 0.2 BTC on June 1 for BRL 12,000? The RFB doesnât let you pick which coins you sold. You must use the first-in, first-out (FIFO) method. That means the first 0.1 BTC you bought (BRL 5,000) and the next 0.1 BTC (BRL 5,500) are your cost basis. Total cost: BRL 10,500. Sale price: BRL 12,000. Profit: BRL 1,500. Tax: BRL 262.50.
Tracking this manually across 10 exchanges, 3 wallets, and 50 trades? Itâs a nightmare. Thatâs why tools like Koinly and CoinTracker are now mandatory for serious traders in Brazil.
What Happens If You Donât Report?
Penalties are brutal. If you underreport or miss a transaction, the RFB can impose fines up to 150% of the unpaid tax. For repeat offenders, they can freeze bank accounts or block asset transfers. The RFB now cross-references data from major Brazilian exchanges like Foxbit, Bitso, and Mercado Bitcoin. They also get transaction data from international platforms like Kraken and Binance via tax treaties.
One trader in SĂŁo Paulo got a letter in August 2025. Heâd made BRL 8,000 in crypto profits in 2024 but didnât report. The RFB had his transaction history from his bankâs crypto-linked debit card. He owed BRL 1,400 in tax, plus BRL 2,100 in penalties. He didnât appeal. He paid.
How Brazil Compares to the Rest of the World
Brazilâs 17.5% rate sits between two extremes:
| Country | Tax Rate | Exemptions | Holding Period Benefit |
|---|---|---|---|
| Brazil | 17.5% flat | None | No |
| Germany | 0% after 1 year | âŹ600 annual tax-free | Yes |
| Portugal | 28% (under 1 year) | 0% if held over 1 year | Yes |
| United Kingdom | 10-20% | ÂŁ3,000 annual allowance | No |
| United States | 10-37% | $0 (but long-term rates apply) | Yes |
Germany rewards long-term holders. Portugal taxes short-term trades harder. The UK gives you a buffer. Brazil? No mercy. No grace period. No safety net. If you profit, you pay.
Whoâs Affected the Most?
Small-time traders feel it the hardest. Someone who buys $100 of Dogecoin every Friday and sells it on Monday for $110? Thatâs $520 in annual profit. Tax: $91. But now they have to track 52 transactions, export CSVs, reconcile wallets, and file a 20-page report. For many, the time cost outweighs the profit.
Professional traders and institutions donât mind. The flat rate simplifies things. No more worrying about whether a gain is short-term or long-term. No complex brackets. Just 17.5%. One number. One rule. Theyâre adapting.
But the real losers? New investors. Brazil had over 30 million crypto users in 2024. Many got in because taxes were low. Now, the barrier to entry has spiked. On Redditâs r/BrazilCrypto, threads like âShould I even bother trading anymore?â are trending.
What About Crypto Mining and Staking?
Yes, theyâre taxed too. If you mine Bitcoin and sell it, you pay 17.5% on the sale price minus your electricity and hardware costs (if you can prove them). Staking rewards? Taxed as income when you receive them, not when you sell. So if you earn 0.05 ETH as staking reward in January and sell it in June, you pay tax twice: once on the value of the ETH when you received it, and again on the gain from that value to the sale price.
DeFi is even messier. Providing liquidity on Uniswap? Taxed on the value of tokens received. Receiving a governance token airdrop? Taxed as income. Even failed transactions that cost gas fees? Those fees arenât deductible. The RFB doesnât recognize them as expenses.
Whatâs Next?
Brazil isnât done. The Central Bank is testing Drex, its own digital currency. The goal? To replace cash and control the flow of money. Crypto taxation is part of that control. More regulation is coming. Expect mandatory KYC for all wallets. Possibly, a blockchain monitoring system linked to banks.
Other Latin American countries are watching. Argentina and Colombia have hinted at similar rules. If Brazilâs revenue targets hit - estimated at BRL 12 billion in 2025 - expect a regional domino effect.
What Should You Do Now?
If you trade crypto in Brazil:
- Export all transaction history from every exchange and wallet since January 1, 2024.
- Use a crypto tax tool like Koinly or CoinTracker - set it to FIFO and Brazil tax rules.
- Calculate your gains and losses for 2024 and 2025 separately.
- Start filing now, even if youâre not sure. The RFB doesnât care if youâre confused - they care if youâre late.
- Keep receipts for hardware, electricity, and software costs. Even if theyâre not deductible now, they might be later.
Thereâs no amnesty. No grace period. The clock started on June 12, 2025. If you havenât filed for 2024, youâre already in violation.
Final Thought
Brazil didnât just tax crypto. It ended the illusion that digital assets were outside the system. This isnât about fairness. Itâs about control. The government now sees every transaction - every swap, every trade, every reward - as part of its revenue stream. Whether you like it or not, crypto in Brazil is no longer a gray area. Itâs a ledger. And the ledger is always watching.
Is crypto trading tax-free in Brazil anymore?
No. As of June 12, 2025, all crypto gains - whether from selling, trading, staking, or mining - are taxed at a flat 17.5%. There are no exemptions, even for small amounts or long-term holdings.
Do I have to report crypto losses?
Yes. If your monthly crypto transactions exceed BRL 5,000, you must report all activity, including losses. You canât offset losses against other income, but reporting them helps avoid suspicion from the tax authority.
What happens if I didnât track my transactions before 2025?
Youâre at risk. The RFB can access data from exchanges and banks dating back to 2023. If you made gains before June 2025 and didnât report, you may owe back taxes plus penalties. Start reconstructing your history using wallet exports and exchange statements.
Can I use foreign exchanges like Binance or Kraken?
Yes, but you still must report all gains. Foreign exchanges share data with Brazil under international tax agreements. Not reporting foreign activity is considered tax evasion and carries heavier penalties.
Are crypto-to-crypto trades taxed?
Yes. Swapping Bitcoin for Ethereum is treated as selling Bitcoin and buying Ethereum. You must calculate the capital gain on the Bitcoin at the time of the swap and pay 17.5% on that profit.
Is there a tax-free allowance in Brazil like in the UK or US?
No. Brazil has no annual tax-free allowance for crypto. Every cent of profit is taxed, regardless of size. Even a $10 gain is subject to 17.5% tax.
Can I deduct mining or gas fees as expenses?
Not officially. The RFB does not currently allow deductions for electricity, hardware, or gas fees. Some tax advisors suggest keeping records in case rules change, but you cannot reduce your taxable gain by these costs right now.
Do I need to report crypto held in wallets, not exchanges?
Yes. The RFB requires you to report all crypto holdings, regardless of where theyâre stored. If you hold BTC in a hardware wallet and sell it, you must report the gain. Youâre responsible for tracking transactions from any wallet you control.
Bro, this is wild đ± I just sold my last 0.1 ETH and got hit with $18 in tax on a $100 profit. Who even designed this? Itâs like the government wants you to stop trading entirely. Iâm just here for memes, not spreadsheets đ€Ą
This is not taxation. This is surveillance capitalism dressed in fiscal clothing. The Brazilian government, in collusion with international financial institutions, has engineered a system to track every digital transaction - not to collect revenue, but to establish total monetary control. The Drex digital currency is the endgame. Theyâre preparing to phase out cash entirely. You are being monitored. Always.
I feel you. I used to trade for fun, now itâs like doing my taxes on a Friday night while my cat stares at me like Iâve betrayed her. I started using Koinly just to survive. Still cry sometimes when I see the âFIFOâ dropdown. Itâs not just tax - itâs emotional labor now. đ
OMG I just realized I didnât report my BNB airdrop from last year!! đ± Iâm so done. Iâm moving to Portugal. At least there they give you a break if you hold for a year. Why did I even start this? I just wanted to buy Dogecoin and meme.
This isnât a tax policy - itâs a psychological operation. The state doesnât want you to profit. It wants you to fear profit. Every time you click âsell,â youâre not just transacting - youâre submitting to a system that reduces your autonomy to a decimal point on a ledger. And yet⊠we keep coming back. Why? Because we still believe in decentralization. Even when the state is watching. Even when itâs taxing every whisper of gain.
