Chainalysis: Global Crypto Tax Non-Compliance Exceeds 90%
In brief
- Chainalysis estimates $457 billion in taxable crypto activity globally in 2025, with only 14% compliance expected
- France reported €368 million in crypto gains against $9.4 billion in estimated taxable activity
- DAC8 directive takes effect January 2026, requiring EU crypto providers to report user transactions
- Self-custody wallets, DeFi protocols, and peer-to-peer trades remain outside reporting infrastructure
France's Reporting Gap
France illustrates the scale of the compliance challenge. Chainalysis estimated France's taxable cryptocurrency activity would reach $9.4 billion in 2025, yet French taxpayers reported €368 million in crypto gains in 2024, representing just 4% of estimated taxable activity. The year prior was even thinner: roughly 7,700 taxpayers declared €150.8 million in 2023.
Chainalysis identified capital gains of $2.5 billion, income from mining and staking of $1.7 billion, and payments of $5.2 billion as components of France's taxable crypto activity. François Volpoet, Director of Chainalysis France, characterized this disparity as evidence of systemic underreporting.
France taxes net capital gains from digital asset disposals at a flat rate of 31.4%, with an annual exemption for disposals under €305. The compliance burden falls on individual taxpayers to self-report transactions—a system that clearly isn't working at scale.
The DAC8 Framework and Its Limits
Regulators are moving to close reporting gaps. Starting January 1, 2026, the DAC8 directive will require crypto service providers operating in EU member states to collect extensive user data and detailed transaction records. The first international data exchanges under DAC8 are scheduled for September 30, 2027.
The framework has structural limits, though. Self-custody wallets, decentralized finance protocols, and peer-to-peer transactions fall outside the reporting infrastructure. Users who move assets off-exchange or conduct trades without intermediaries remain largely invisible to tax authorities. DAC8 captures custodial flows—not the entire ecosystem.
