Senate voted to overturn the IRS DeFi broker rule

Senate voted to disapprove the rule

The U.S. Senate voted 70-27 on March 4, 2025 to pass S.J.Res. 3, a Congressional Review Act resolution aimed at overturning the Internal Revenue Service’s reporting rule for certain decentralized-finance services. Three senators did not vote, according to the official roll call.

The result was a major legislative rebuke to the rule, but it was not a repeal on March 4. The House of Representatives still had to pass a disapproval resolution and the president had to sign it before the IRS rule would lose legal effect. For DeFi operators and users, the immediate change was therefore political probability, not an operative change in tax law or reporting duties.

What the IRS rule covered

Treasury and the IRS finalized “Gross Proceeds Reporting by Brokers That Regularly Provide Services Effectuating Digital Asset Sales” on December 27, 2024, and published it in the Federal Register on December 30. The rule expanded broker information reporting to defined “digital asset middlemen,” including covered trading front-end service providers that enable customers to interact with decentralized trading applications and ordinarily know, or are in a position to know, the nature of a transaction.

That definition was narrower than the claim that every developer or protocol participant became a broker. The rule focused on persons providing specified front-end or effectuating services, while its analysis distinguished those services from activities such as merely providing some forms of software or operating validation infrastructure. For covered sales occurring on or after January 1, 2027, affected brokers would have to file information returns and furnish customer statements reporting gross proceeds.

The agency’s stated rationale was tax administration. Treasury and the IRS argued that information reporting would help identify taxpayers engaged in digital-asset transactions, remind customers that dispositions may be taxable, and put covered DeFi services on a reporting footing closer to other brokers.

Why the Senate objected

S.J.Res. 3, introduced by Senator Ted Cruz of Texas on January 21, used the Congressional Review Act’s expedited process to challenge the entire final rule. In Senate debate on March 4, Cruz argued that noncustodial front ends could not practically perform intermediary-style collection and reporting, and that imposing those duties would create privacy, compliance and competitiveness costs. Those were the sponsor’s contemporaneous policy claims, not findings established by the vote.

The 70-vote majority nevertheless mattered institutionally. It showed that opposition extended well beyond a narrow party-line bloc and that Congress was willing to use the CRA against a crypto-specific tax regulation completed at the end of the prior administration. The resolution’s text was categorical: if enacted, Congress would disapprove the rule and it would have no force or effect.

The dispute also exposed a recurring DeFi-policy problem. A blockchain protocol may execute transfers through smart contracts without a conventional custodian, yet many users reach it through a website or other interface maintained by an identifiable operator. Treasury treated some of those interfaces as sufficiently involved to report. Opponents said that approach assigned broker duties to services that do not possess customer assets or the information conventional brokers hold.

What was unresolved on March 4

The Senate vote did not eliminate taxes on digital-asset gains, alter taxpayers’ underlying recordkeeping obligations, or settle which DeFi businesses could comply with the rule. It also did not establish a measurable crypto-market reaction. No named instrument, venue and event window in the reviewed record isolated the vote from simultaneous macroeconomic and policy news.

As of March 4, 2025, the verified development was narrower and still consequential: one chamber of Congress had passed a bipartisan resolution to erase the IRS’s DeFi broker-reporting framework, while the rule’s ultimate legal fate remained open.
