In Brazil, cryptocurrencies are generally treated as assets for tax purposes rather than as legal tender or foreign currency. This means that most taxation occurs when crypto assets are sold, exchanged, or otherwise disposed of for a profit. Individuals who buy and hold digital assets are typically taxed under capital gains rules when they realize gains.
The Brazilian tax authority, the Receita Federal do Brasil (RFB), has issued guidance confirming that cryptocurrency transactions may generate taxable capital gains.
Taxation depends largely on the size of the transaction and the nature of the activity. Casual investors are generally taxed under capital gains rules, while activities resembling business operations may fall under ordinary income taxation.
Brazil has historically provided a monthly exemption for smaller crypto disposals. However, ongoing policy discussions suggest that the government intends to align crypto taxation more closely with other financial investments.
In particular, Provisional Measure No. 1,303/2025 proposes a unified tax structure for financial assets and cryptocurrencies, which could remove existing exemptions if enacted.
Capital Gains Tax Rules
Capital gains tax is the primary mechanism through which cryptocurrency transactions are taxed in Brazil. When an individual disposes of cryptocurrency and realizes a profit, the gain may be subject to taxation depending on the total value of disposals within the month. If total sales in a given month exceed BRL 35,000, the resulting gains become taxable.
Taxable events typically include selling cryptocurrency for fiat currency, exchanging one cryptocurrency for another, and using cryptocurrency to purchase goods or services.
The RFB confirmed in Binding Ruling No. SC 214/2021 that crypto-to-crypto transactions are treated as taxable events even when no fiat currency is involved. This interpretation has been challenged through Legislative Decree No. PDL 3/2022, but the matter has not yet been conclusively resolved.
How capital gains are calculated
Capital gains are calculated as the difference between the disposal value and the cost basis of the cryptocurrency. The disposal value is generally the fair market value of the asset at the time of the transaction, expressed in Brazilian reais. If multiple units were acquired at different prices, taxpayers must apply consistent accounting methods to determine the cost basis.
Brazil applies progressive tax rates to capital gains exceeding the exemption threshold. Gains are taxed starting at 15% and may increase to 22.5% for larger amounts. Proposed reforms in Provisional Measure No. 1,303/2025 aim to standardize taxation by introducing a flat 17.5% rate across financial investments and cryptocurrency gains.
Record keeping
Taxpayers are expected to maintain detailed records of all cryptocurrency transactions. These records should include acquisition dates, purchase prices, transaction values in Brazilian reais, and evidence of transfers between wallets or exchanges. Accurate documentation is essential for calculating gains and demonstrating compliance in case of tax authority review.
Income Tax Rules
While many crypto investors fall under capital gains taxation, certain activities may be treated as ordinary income. This generally occurs when cryptocurrency transactions are conducted in a manner resembling a business activity, such as professional trading or operating a crypto-related service.
Income tax may also apply when individuals receive cryptocurrency as payment for goods or services. In such cases, the value of the cryptocurrency at the time of receipt is treated as taxable income and must be converted into Brazilian reais for reporting purposes.
The taxpayer then establishes a cost basis equal to that value for future capital gains calculations when the asset is later sold.
Brazil has not issued comprehensive statutory rules specifically addressing all forms of crypto income. As of 2025, guidance remains primarily administrative, relying on general income tax principles and the interpretations issued by the RFB.
Mining and Staking Treatment
Mining
Cryptocurrency mining may generate taxable income when new coins are received as block rewards. In practice, mining activity may be treated either as business income or as individual income depending on the scale and organization of the operation. Large-scale mining operations with dedicated infrastructure are more likely to be classified as commercial activity.
Treating mining as a business may allow taxpayers to deduct certain operational expenses like equipment, electricity, and maintenance. Brazil has also provided temporary incentives for mining infrastructure. The Chamber of Foreign Trade established a 0% import tax on SHA-256 mining hardware and hardware wallets until 31 December 2025 to encourage industry development.
When mined cryptocurrency is later sold, the transaction may also trigger capital gains tax based on the difference between the disposal value and the value previously recognized as income.
Staking
Staking rewards may similarly be treated as taxable income when received. The fair market value of the tokens at the time they are credited to the taxpayer’s wallet is typically used as the basis for income recognition.
When staked assets or rewards are later sold or exchanged, a separate capital gains calculation applies. The previously recognized income value becomes the cost basis for determining any gain or loss upon disposal. As of 2025, Brazil has not issued detailed legislation specifically addressing staking, so existing income tax principles are generally applied.
NFT Taxation
Non-fungible tokens (NFTs) are generally treated in the same way as other digital assets under Brazilian tax principles. When NFTs are purchased and later sold for a profit, the gain may be subject to capital gains tax if the monthly disposal threshold of BRL 35,000 is exceeded.
Investors holding NFTs as collectibles or speculative assets must calculate gains based on the difference between the purchase price and the sale price in Brazilian reais. The same reporting and record-keeping obligations that apply to cryptocurrencies also apply to NFT transactions.
Individuals who create and sell NFTs as part of a commercial activity may instead be taxed under ordinary income rules. In such cases, proceeds from NFT sales may be treated as business income rather than capital gains. As of 2025, Brazil has not issued detailed tax guidance specific to NFTs, so treatment largely follows the broader framework applied to digital assets.
Reporting Requirements
Brazilian taxpayers must report cryptocurrency holdings and transactions in their annual income tax return. When the acquisition cost of crypto assets reaches or exceeds BRL 5,000, the holdings must be declared in the “Assets and Rights” section of the return. The declaration should include the type of asset, acquisition date, and purchase value expressed in Brazilian reais.
Capital gains arising from taxable crypto disposals must be calculated and reported through the relevant capital gains reporting mechanisms before being incorporated into the annual return. Taxpayers must ensure that all values are converted into Brazilian reais at the appropriate market exchange rate on the transaction date.
The RFB has increasingly emphasized transparency and formalization within the crypto sector. Exchanges and financial intermediaries may be required to report transaction data to tax authorities, allowing cross-verification of taxpayer disclosures.
Taxpayers should retain documentation supporting all crypto transactions, including trade confirmations, wallet addresses, exchange statements, and conversion rates used in calculations. Maintaining accurate records is essential to demonstrate compliance if the tax authority conducts an audit or review.
Penalties
Failure to report cryptocurrency gains or income can result in financial penalties under Brazil’s general tax enforcement framework. Penalties may apply when taxpayers omit taxable transactions, incorrectly calculate gains, or fail to include required asset declarations in their annual return.
Failure to comply can result in a fine of between BRL 1,500 and 3% of the undeclared amount. In 2025, these requirements were updated but maintained their essence, complete transparency of transactions, to monitor taxes.
Also, the severity of penalties typically depends on the level of non-compliance and whether the omission is considered negligent or intentional. In addition to monetary penalties, interest charges may accrue on unpaid tax amounts until the liability is settled.
Voluntary correction of tax filings may reduce potential penalties. Taxpayers who identify errors or omissions in previous filings are generally encouraged to amend their returns and disclose the correct information to the tax authority before enforcement actions occur.
