Crypto tax rules may miss 86% of $457B in onchain activity, Chainalysis says

Chainalysis released research suggesting that roughly $457 billion in potentially taxable cryptocurrency activity occurred onchain globally in 2025, yet current international tax reporting frameworks capture only about 14% of these transactions. The gap underscores a compliance challenge as the Common Reporting Standard for Automatic Exchange of Information (CARF) rolls out internationally. The discrepancy points to limitations in how existing regulatory infrastructure tracks distributed ledger activity, leaving a significant portion of taxable events outside the scope of coordinated reporting mechanisms that governments are now implementing.

This finding highlights friction between the scale of onchain activity and the maturity of enforcement infrastructure. Regulators face technical and jurisdictional hurdles in capturing transactions that may cross borders, use non-custodial wallets, or occur on decentralized platforms.

• Chainalysis estimates $457B in potentially taxable onchain activity in 2025, with only 14% falling within reach of international reporting rules.
• The visibility gap exposes limits in CARF and similar frameworks as they begin coordinated implementation across jurisdictions.
• The research suggests ongoing compliance challenges for both regulators and market participants navigating evolving tax infrastructure.
