US, Brazil, Korea plan tougher crypto tax rules

November 22, 2025

US, Brazil, and South Korea are moving toward stricter crypto tax rules, from global reporting to cross-border levies, as trading and stablecoin use grow.

US, Brazil, Korea plan tougher crypto tax rules

Crypto tax rules are tightening. Governments in the United States, Brazil, and South Korea are advancing new measures that would expand reporting and levy taxes on more kinds of digital asset activity, including cross-border transfers and trading profits.

The U.S. pushes global reporting and explores Bitcoin payments

On Nov. 17, the White House unveiled Treasury proposals to align the U.S. with the Crypto-Asset Reporting Framework (CARF), a data-sharing standard created in 2022 to help tax agencies swap information on crypto users across borders. CARF already counts crypto-friendly hubs like the UAE and Japan, alongside G7 nations such as Canada and Germany.

In plain terms, CARF would make it easier for tax authorities to receive transaction data from foreign exchanges and wallet providers, similar to how banks report interest and dividends today.

U.S. tax treatment remains the same for now: crypto is property, so trades can trigger capital gains. Notably, the stock markets wash sale rulewhich stops investors from claiming a tax loss if they buy back the same asset within 30 daysdoesnt currently apply to crypto.

Separately, a new bill, the Bitcoin For America Act, introduced by Rep. Warren Davidson this week, would let Americans pay federal taxes in Bitcoin. Under the proposal, those BTC payments would flow into a Strategic Bitcoin Reserve, aligning with the administrations stated goal of making the U.S. a leading crypto hub.

Brazil eyes taxes on cross-border crypto transfers

Brazil is weighing an expansion of its financial transaction tax to cover international transfers involving stablecoins and other digital assets, according to a Reuters report on Nov. 18. The change, targeted for 2026, would tax those transfers much like traditional foreign exchange transactions.

Brazil already taxes crypto gains, but the new approach would pull border-spanning stablecoin and crypto payments into the same bucket as fiat remittancesa notable shift as more Brazilians use dollar-pegged tokens for savings and payments.

South Korea sets a 20% levy on trading profits

South Korea is preparing a flat 20% tax on cryptocurrency trading profits starting in 2027, per a widely cited country guide. The rollout has been delayed several times since 2021, so traders will watch whether this timeline sticks. Until then, gains on crypto trades can still be taxed under existing rules.

Why this matters

  • More data sharing: CARF would make it harder to hide crypto income across borders, raising compliance expectations for exchanges and brokers.
  • Stablecoins in the spotlight: Brazils plan to tax cross-border stablecoin transfers signals regulators are treating tokenized dollars more like regular money movement.
  • Clearer playbooks for traders: Koreas flat-rate approach gives investors a number to plan around, even if the date shifts again.

What could change for users

  • Greater documentation: Expect more requests for identification and tax forms from exchanges, especially for cross-border activity.
  • Fewer tax-loss strategies: If U.S. lawmakers ever extend wash sale rules to digital assets, common tactics for harvesting losses could narrow.
  • Remittance costs: In Brazil, sending stablecoins abroad may resemble traditional FX transfers on taxes and fees if the proposal becomes law.

The bigger picture

This is part of a broader move to normalize crypto within financial law. Decentralized Finance (DeFi) and stablecoins are no longer niche; theyre used by millions for trading, remittances, and savings. As usage grows, tax systems are catching up with frameworks that mirror those used for stocks, bank accounts, and international wire transfers.

Key dates to watch

  • Nov. 17: U.S. proposes cooperation with CARF.
  • 2026: Brazil targets start date for cross-border crypto transfer taxes (Reuters).
  • 2027: South Korea aims to implement a 20% tax on crypto trading profits (guide).

Bottom line

Rules are converging: more reporting, clearer rates, and broader tax coverage. For investors, that means tracking cost basis, saving trade records, and expecting stricter complianceespecially for cross-border transactions and stablecoin transfers.
