Cynthia Lummis, Wyoming’s senior U.S. senator and a prominent crypto advocate in Congress, is leveraging her final years in office to push for a tax break on small cryptocurrency transactions. As the Senate continues to deliberate on comprehensive digital asset legislation, Lummis has revived her proposal for a “de minimis” tax exclusion, aiming to make everyday Bitcoin (BTC) use more practical by shielding minor transactions from capital gains taxes.
Lummis Revives Push for Crypto Transaction Tax Exemption
In a recent CNBC interview, Lummis revealed that both the House Ways and Means Committee and the Senate Finance Committee are evaluating a proposal to exempt crypto transactions under $300 from capital gains reporting. This aligns with her standalone bill introduced in July 2025, which would establish a $300 per-transaction de minimis exemption with an annual aggregate limit of $5,000.
“We’re trying to figure out how to weigh, the appropriate way, to decide when a sale — for example of Bitcoin — should be subject to capital gains and when it should be allowed to be used as a simple means of exchange the same way we use the US dollar,” Lummis explained, framing the issue as one of functional utility versus investment treatment.
Lummis, who serves on the Senate Banking Committee, has long championed crypto-friendly policies, mirroring Wyoming’s reputation as a pioneering state for digital asset regulation. Her current push seeks to address a common pain point for crypto users: the administrative burden of reporting minute gains or losses on everyday purchases, from coffee to online services.
CLARITY Act Faces Senate Stalemate Amid Key Concerns
Lummis’s tax exemption drive runs parallel to her fierce advocacy for the broader market structure bill, which passed the House in July 2025 as the CLARITY Act. That legislation aims to clarify regulatory jurisdiction over digital assets, primarily between the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC).
However, the Senate version has hit a wall. A scheduled markup before the Senate Banking Committee was indefinitely postponed in January after Coinbase CEO Brian Armstrong publicly stated the exchange could not support the bill “as written,” citing unresolved issues around tokenized equities. Lummis confirmed that key Democratic committee members remain unconvinced, stalling the bill’s momentum.
Postponed Markup and Industry Concerns
Beyond tokenized equities, the legislation faces a raft of concerns: questions about the proper role of U.S. financial regulators, ethical debates over potential conflicts of interest for lawmakers, and disputes over whether stablecoin issuers should be permitted to generate yield for holders.
