Global crypto taxable activity hits $457 billion, but most remains unreported

Blockchain data reveals $457 billion in taxable crypto activity

A new report from blockchain analytics firm Chainalysis estimates that global taxable crypto activity reached $457 billion in 2025. The figure includes profits from selling crypto, earnings from activities like mining and staking, and payments made using crypto on six major blockchains. However, the report highlights that most of this activity is not captured by current international tax-reporting rules.

The U.S. accounted for $112.6 billion of the total, making it the largest single country. North America led all regions with $134.6 billion, followed by the European Union at $125.1 billion. The report did not include trading or other transactions conducted on centralized exchanges.

Key findings from the Chainalysis report

• Global taxable crypto activity in 2025: $457 billion
• U.S. share: $112.6 billion
• North America total: $134.6 billion
• European Union total: $125.1 billion
• Only 14% of onchain activity is covered by current tax-reporting rules
• 86% of taxable activity occurs on decentralized platforms, peer-to-peer transfers, or onchain income streams

OECD’s tax framework misses most onchain transactions

The Organisation for Economic Co-operation and Development (OECD) introduced the Crypto-Asset Reporting Framework (CARF) in 2022 to improve tax transparency for crypto transactions. CARF requires crypto service providers to report customer transaction data to tax authorities, which can then share it across borders. Data collection under CARF began on January 1, 2026, in 48 jurisdictions, including the U.K. and the European Union.

However, Chainalysis found that CARF covers only 14% of the taxable onchain activity it identified. The remaining 86% includes transactions on decentralized exchanges, peer-to-peer transfers, onchain income streams, and crypto payments. These activities often lack a centralized operator or custodian, making them difficult to track under the current framework.

Why decentralized finance falls outside tax rules

CARF was designed around intermediaries—companies that facilitate crypto transactions as a business. This approach works for centralized exchanges but leaves gaps in decentralized finance (DeFi), where transactions often occur without a middleman. Colby Mangels, a former OECD adviser who worked on CARF, explained that tax authorities are monitoring developments in anti-money laundering regulations to determine when DeFi platforms might be treated as regulated crypto service providers.

What is confirmed

• Chainalysis estimates $457 billion in global taxable crypto activity for 2025.
• The U.S. accounted for $112.6 billion of this total.
• CARF covers only 14% of onchain taxable activity, according to Chainalysis.
• CARF data collection began on January 1, 2026, in 48 jurisdictions.

What is still unclear

• How tax authorities will address the 86% of onchain activity not covered by CARF.
• Whether future regulations will expand reporting requirements to decentralized platforms.
• The timeline for potential changes to CARF or similar frameworks.

Why this matters for crypto users and regulators

The report highlights a significant gap in tax reporting for crypto transactions. While CARF improves transparency for centralized exchanges, most onchain activity remains outside its scope. This could lead to challenges for tax authorities in tracking taxable income and enforcing compliance. For crypto users, the findings underscore the importance of understanding tax obligations, especially for activities like staking, mining, or trading on decentralized platforms.
