TL;DR
- Brazil has implemented a flat 17.5% tax on all individual crypto profits through Provisional Measure 1303, replacing a progressive tax regime.
- The R$35,000 monthly exemption (approx. $6,300) has been eliminated, impacting small retail investors.
- The tax applies regardless of where assets are held, including foreign exchanges and self-custody wallets.
- Losses can be offset, but only within a rolling five-quarter window—a policy that will tighten in 2026.
- This overhaul comes as Brazil’s government drops a proposed IOF financial transaction tax hike and seeks broader tax revenue expansion.
Brazil’s New Crypto Tax Regime: A Radical Shift
The Brazilian government has officially ended its long-standing tax exemption for small crypto transactions by imposing a flat 17.5% capital gains tax on all individual profits derived from digital assets.
Announced under Provisional Measure 1303, the new rule marks a significant departure from the previous framework, which had exempted monthly transactions under R$35,000 (~$6,300 USD) and imposed progressive tax rates up to 22.5% for higher volumes.
Now, all individual crypto gains—regardless of transaction size or holding location—are subject to a uniform 17.5% tax.
Impact on Small vs. Large Investors
The newly introduced flat rate is expected to hit retail investors hardest. Under the old model, individuals conducting modest trades were entirely exempt from taxation. By removing this exemption, Brazil now requires every crypto sale with profit to be declared and taxed, even if the value is small.
Conversely, high-net-worth individuals may benefit under the new system. For example:
- Previously, profits over R$5.4 million (~$970,000 USD) faced a 22.5% tax.
- Now, the same earnings are taxed at 17.5%, creating a relative tax reduction.
This change effectively shifts the burden toward smaller holders, raising concerns among grassroots crypto communities and consumer protection groups.
“The new measure favors whales and penalizes small investors,” said a local analyst speaking to Portal do Bitcoin.

Global and Domestic Holdings Now in Scope
In a noteworthy development, the new tax will apply regardless of where the crypto assets are stored. This includes holdings in:
- International exchanges like Binance, Coinbase, or Kraken
- Self-custodial wallets like MetaMask, Ledger, or Trezor
By enforcing tax obligations on globally held digital assets, Brazil is taking a page from other jurisdictions such as the U.S. and Australia, which already demand that citizens report worldwide crypto activity.
Experts say this move reflects the government’s ambition to tighten oversight on decentralized finance and improve domestic tax compliance.
Losses Can Be Offset—But with a Time Limit
Another critical aspect of MP 1303 is the structured loss offset window. Investors may deduct losses from gains, but only within a rolling five-quarter period. That means if a loss occurs in Q1 2025, it must be used before Q2 2026.
In 2026, this rule is expected to become even more stringent, although the specifics have not been disclosed yet. Investors will need to engage in rigorous tax planning, especially those involved in high-volatility or swing trading.
Government’s Broader Fiscal Strategy
This overhaul of the crypto tax regime isn’t happening in a vacuum. It follows the Brazilian government’s decision to abandon a controversial plan to increase the IOF (Imposto sobre Operações Financeiras), a financial transaction tax that applies to credit, insurance, and foreign exchange.
After pushback from financial institutions and Congress, the government retracted the IOF hike and instead redirected its focus to more emerging and digitally active markets—namely crypto, fixed-income assets, and online betting.
According to official government statements, the crypto tax measure is part of a multi-pronged fiscal strategy aimed at raising tax revenue without alienating the traditional banking sector.
“We’re aligning tax treatment across asset classes in the digital economy,” said a spokesperson from the Ministry of Finance.
Additional Changes to Financial Asset Taxation
Alongside crypto, Provisional Measure 1303 also introduces new tax guidelines for other sectors:
- Fixed-Income Investments – Subject to a fixed 5% tax on earnings
- Online Betting Operators – See their tax burden rise from 12% to 18% on revenue
These measures are expected to streamline tax collection while ensuring the government captures a larger share of profits from digitally active sectors.
Analysts believe this is just the beginning, and other digital asset classes like NFTs, DeFi protocols, and stablecoins may soon face similar scrutiny.
Reactions from the Crypto Community
The response from Brazil’s crypto community has been mixed. While some welcome the clarity and consistency of a flat tax, many retail users argue that the elimination of the R$35,000 exemption will discourage adoption and punish small-scale users.
Brazil is home to over 4 million crypto users, according to recent Statista data, making it one of the largest retail crypto markets in Latin America. The abrupt shift in taxation has therefore sparked widespread discussion on platforms like X (formerly Twitter) and Telegram investor groups.
Some users have called for more inclusive tax brackets that protect small holders, while others are exploring offshore legal structures to mitigate exposure.
What Happens Next?
The new tax law takes immediate effect, but investors will first feel its impact during 2025 income tax filings in 2026. Tax advisors across Brazil are urging clients to:
- Track every transaction, including fees and exchange rates
- Log all losses in real time
- Prepare for audits, especially on foreign wallets and exchanges
There are also growing calls for the Brazilian Congress to formalize or amend the provisional measure to address inequality concerns and define enforcement mechanisms.
Whether these provisions evolve or become even stricter will depend on future budget debates and lobbying from crypto stakeholders in Brasilia.
