Key highlights include a threshold, or de minimis rule, of $300 on crypto transactions, elimination of double taxation for crypto miners and stakers and tax parity – treating of crypto like other financial assets. The bill also proposes expanding securities lending rules to include digital assets, clarifying that digital asset lending is generally not a taxable event. “In order to maintain our competitive edge, we must change our tax code to embrace our digital economy, not burden digital asset users,” said Lummis. “This groundbreaking legislation is fully paid-for, cuts through the bureaucratic red tape and establishes common-sense rules that reflect how digital technologies function in the real world.” According to Lummis, it’s time America does not allow its “archaic tax policies” to stifle innovation. “My legislation ensures Americans can participate in the digital economy without inadvertent tax violations,” she added. In a statemen, Lummis said she welcomes public comments on the bill.
