Congressional intervention rescued the decentralized finance sector from what many considered regulatory overreach when the Senate and House successfully wielded the Congressional Review Act like a legislative scalpel, excising Treasury’s December 2024 DeFi regulations that would have transformed autonomous protocols into glorified tax collectors.
The joint resolutions, passed on March 4 and 11, 2025, represented an unprecedented pushback against Treasury’s ambitious interpretation of the Infrastructure Investment and Jobs Act’s broker reporting requirements. Treasury’s December regulations had extended IRC Section 6045’s reach beyond custodial platforms—already subject to reporting rules since January 2025—into the wild west of noncustodial DeFi protocols, where algorithms execute trades without human intermediaries.
Uniswap and venture capital powerhouse A16z led the charge against these regulations, arguing that imposing traditional broker-dealer compliance frameworks on decentralized protocols was akin to requiring highway asphalt to collect tolls. The burden of detailed tax reporting would have fundamentally altered DeFi’s architecture, potentially driving innovation offshore to jurisdictions with lighter regulatory footprints.
The industry’s concerns extended beyond mere compliance costs. DeFi platforms operate through smart contracts and automated market makers—hardly the centralized entities Congress likely envisioned when crafting broker reporting requirements. The regulatory uncertainty surrounding the distinction between custodial and noncustodial platforms created a legal gray area that threatened to stifle the sector’s rapid growth.
President Biden’s April 10 signature on the disapproval resolutions marked a historic moment: the first time Congress used the CRA to overturn Treasury tax regulations. This legislative intervention exploited the CRA’s reset mechanism when the 119th Congress convened, extending the review period for rules finalized in the previous session’s waning days. With President Trump now expected to provide presidential approval, the joint resolution will officially take effect and nullify the DeFi regulations.
The implications ripple beyond immediate relief. The CRA’s prohibition against “substantially similar” regulations effectively handcuffs Treasury and IRS from pursuing comparable DeFi oversight for the foreseeable future, creating a regulatory void around decentralized protocols. The congressional action demonstrated exceptional bipartisan support, with the Senate vote reaching 70-28 in favor of blocking the regulations.
While this delivers the exemption A16z and others demanded, it leaves questions about how tax authorities will eventually address the unique challenges posed by autonomous financial systems operating without traditional intermediaries. The compliance costs that DeFi platforms would have faced could have reached hundreds of thousands annually, mirroring the operational expenses seen across the broader cryptocurrency sector.
