If you play at crypto casinos and earn winnings in cryptocurrency, understanding your tax obligations in Brazil is essential. The Receita Federal (Brazil's federal tax authority) has been increasing its oversight of crypto operations, and ignorance of the law does not exempt anyone from fines and penalties.

Brazilian Legislation on Crypto Assets
Brazil has a growing regulatory framework for crypto assets. Key regulations include:
IN RFB 1.888/2019
This was the first specific regulation from the Receita Federal on crypto assets. It established reporting obligations for individuals conducting crypto transactions over R$30,000 per month and required Brazilian exchanges to report all client operations to the tax authority.
Crypto Assets Legal Framework (Law 14.478/2022)
Approved in December 2022, this law brought greater legal certainty to Brazil's crypto market, establishing rules for virtual asset service providers and anti-money laundering measures.
How Crypto Gains Are Taxed
In Brazil, crypto gains are taxed as capital gains. This applies whenever there is profit from the disposal (sale, exchange, or use) of cryptocurrencies.
Tax-Triggering Events
Tax is due when you dispose of crypto assets at a profit. For crypto casino players, this occurs when you convert crypto winnings to BRL, exchange one crypto for another, or withdraw and sell at an exchange.
Monthly Exemption of R$35,000
Individual taxpayers are exempt from capital gains tax if total crypto disposals in a month are below R$35,000. Note that this threshold applies to total sales value, not just profit. If exceeded, all gains become taxable.
Capital Gains Tax Rates
| Capital Gain | Tax Rate |
|---|---|
| Up to R$5,000,000 | 15% |
| R$5,000,001 to R$10,000,000 | 17.5% |
| R$10,000,001 to R$30,000,000 | 20% |
| Above R$30,000,000 | 22.5% |
For the vast majority of crypto casino players, the applicable rate will be 15%.
Calculating Capital Gains from Crypto Casinos
The calculation follows three steps:
- Determine acquisition cost: The amount you paid for the crypto you deposited at the casino.
- Determine disposal value: The amount you received when converting your crypto winnings to BRL or another asset.
- Calculate the gain: Disposal value minus acquisition cost equals your capital gain.
Practical Example
Suppose you bought 0.2 BTC for R$60,000, deposited it at a crypto casino, and after playing you have 0.35 BTC. You withdraw and sell for R$122,500. Your capital gain is R$122,500 - R$60,000 = R$62,500, and tax due is R$62,500 x 15% = R$9,375.
DARF — Paying the Tax
Capital gains tax must be paid monthly through a DARF (Federal Revenue Collection Document), using revenue code 4600, by the last business day of the month following the operation. Late payments incur a daily penalty of 0.33% (capped at 20%) plus Selic interest.
Annual Income Tax Return
Beyond monthly DARF payments, crypto assets and gains must be reported in the annual income tax return. Crypto holdings above R$5,000 must be declared under group 08 (Crypto Assets) in the Assets and Rights section.
How Exchanges Report to the Receita Federal
Brazilian exchanges must report all client transactions to the Receita Federal. For operations at foreign exchanges (including most crypto casinos), the taxpayer is responsible for reporting when monthly values exceed R$30,000.
Common Mistakes to Avoid
- Failing to report: Can result in fines of 75% to 150% of tax owed
- Confusing exemption with non-reporting: Even exempt gains must be declared annually
- Not keeping records: Always save deposit/withdrawal receipts and transaction history
- Incorrect acquisition cost: Use weighted average cost method
- Late DARF payments: Pay monthly to avoid accumulated penalties
When to Hire an Accountant
We strongly recommend hiring a crypto-specialized accountant if you have high transaction volume, significant winnings, operations across multiple platforms, or international operations. The cost (R$500-R$2,000 per return) is minimal compared to potential penalties for errors or omissions.
To play at platforms like Stake and BC.Game with peace of mind, keep detailed records, pay DARF monthly when due, and report everything correctly in your annual return.
