The IRS says covered digital asset brokers must issue Form 1099-DA for 2026 sales and trades, while advanced forensic audits will continue targeting on-chain activity despite the DeFi broker rule repeal.
The IRS entered a new enforcement phase on April 15 tied to mandatory digital asset cost-basis reporting for the 2026 tax year. Centralized exchanges, custodial wallet providers, and some digital asset processors must issue Form 1099-DA for each digital asset sale and trade, extending reporting beyond transaction proceeds to include cost basis used to calculate gains or losses. The agency also said advanced forensic audits will continue to target on-chain activity even after the repeal of the DeFi broker rule, signaling continued scrutiny of crypto tax compliance beyond covered broker reporting.
