House Committee to Mark Up Comprehensive Crypto Tax Bill

The U.S. House Ways and Means Committee is scheduled to begin markup of a comprehensive cryptocurrency tax bill on Wednesday, September 16, 2026. The legislation, the Digital Asset Tax Certainty Act (H.R. 10357), aims to establish a clearer tax framework for digital assets by addressing issues from small transaction fees to the treatment of mining and staking rewards. The 114-page bill proposes a de minimis tax exemption for qualifying blockchain network and transaction fees under $10. This exemption would not apply to users who completed more than 5,000 transfers in the previous year. The package also extends wash sale and constructive sale rules to digital assets, a change estimated to raise $2.074 billion in revenue over fiscal years 2026 through 2036. Qualified U.S. dollar stablecoins would be excluded from these new wash sale provisions. A central point of contention in the bill's development has been the tax timing for mining and staking rewards. The final markup text omits a key provision that would have allowed taxpayers to defer recognizing income from these activities until the tokens are sold.
