This bill, titled the "Digital Asset PARITY Act," seeks to establish a comprehensive framework for the tax treatment of digital assets within the Internal Revenue Code. It addresses several key areas, including the taxation of stablecoins, digital asset lending, and income derived from validation activities. The legislation also aims to align digital asset transactions with existing tax principles where appropriate. For regulated payment stablecoins , the bill generally provides for no gain or loss recognition on sale or exchange unless the taxpayer's basis is less than 99 percent of the redemption value. It also extends wash sale rules and constructive sale rules to include digital assets, aiming to prevent tax loss harvesting and certain tax avoidance strategies. Furthermore, it allows for a mark-to-market election for dealers and traders in actively-traded digital assets, similar to securities. The bill introduces new rules for digital assets acquired through validation activities (like mining or staking), generally including their fair market value in gross income as ordinary income. However, taxpayers can elect to defer income inclusion and capitalize related expenses until disposition, at which point gains or losses are treated as ordinary. It also amends rules for digital asset lending agreements , treating substitute payments to lenders in lieu of staking rewards or fees as gross income. A digital asset trading safe harbor is established for non-dealers trading for their own account, preventing such activities from automatically constituting a U.S. trade or business for foreign persons. For charitable contributions of digital assets , actively traded digital assets are exempt from qualified appraisal requirements, while infrequently traded assets have specific substantiation rules. The bill also provides detailed definitions for various digital asset terms, including "digital asset," "actively traded digital asset," and "validation activity." Finally, the bill mandates a study and report by the Secretary of the Treasury on the compliance burden of small digital asset transactions and potential de minimis exclusions. It also requires interim guidance on categories of digital asset transactions eligible for gain or loss recognition relief under existing authority.
