Global on-chain crypto activity that could potentially be subject to taxation totaled at least $457 billion in 2025, according to estimates from Chainalysis, with the United States accounting for $112.6 billion.
The estimate covers realized gains on centralized and decentralized exchanges, as well as income generated through mining, staking, and lending. Crypto payments are also included in the calculation.
Chainalysis described the global figure as a conservative lower bound because transactions conducted off-chain within centralized exchanges cannot be observed through on-chain data.
Moreover, the blockchain analytics firm estimated that about 14% of global on-chain potentially taxable activity is within the practical scope of the OECD’s Crypto-Asset Reporting Framework.
Most activity involving decentralized exchanges, peer-to-peer transactions, self-custody, on-chain income and crypto payments falls outside the framework’s practical coverage, according to Chainalysis.
