Official title: To impose additional sanctions with respect to Iran and modify other existing sanctions with respect to Iran, and for other purposes.
Introduced April 1, 2025 by Zach Nunn · Last progress April 1, 2025
The bill substantially strengthens sanctions, enforcement, oversight, and victim‑support tools to constrain Iran and its proxies, but does so at the cost of higher economic and administrative burdens, reduced diplomatic flexibility, humanitarian risks, and an increased chance of regional escalation.
Taxpayers, U.S. forces, and regional allies will see reduced Iranian capability to fund proxies, acquire missiles/drones, and advance nuclear activities because the bill reimposes, expands, and hardens sanctions and freezes targeted funds.
Congress, oversight bodies, and the public gain more visibility and control because the bill requires frequent reports, certifications, and (in some cases) Senate or congressional reviews for Iran-related actions.
Victims of state-sponsored terrorism and U.S. national-security efforts benefit because the bill creates victim-compensation funds, expands the Rewards Program, and authorizes mechanisms to identify, freeze, and repurpose Iranian assets for accountability and civil-society support.
Taxpayers, service members, and regional partners face a heightened risk of escalation and broader conflict because the bill's expanded sanctions, hardline posture, and public pressure increase chances of retaliatory or kinetic responses by Iran or its proxies.
U.S. consumers, businesses, and taxpayers will likely see higher costs and economic disruption because prolonged or expanded sanctions can raise defense spending, disrupt trade and shipping, and increase compliance costs for banks and firms.
Presidents and diplomats have reduced flexibility to negotiate because statutory bans on waivers, strict certification/ratification requirements, and hardline conditions limit the Executive Branch's ability to pursue rapid or creative diplomacy.
Based on analysis of 22 sections of legislative text.
Codifies and tightens sanctions on Iran, restricts waiver/licensing authority, expands reporting/designations, and directs frozen funds to a victims compensation fund.
Strengthens and codifies U.S. sanctions and restrictions on Iran and Iran-linked persons, sharply limits executive waiver and licensing authorities, and expands reporting, designation, and sanction-triggering rules. It requires the preservation and reimposition of many preexisting Iran sanctions, directs new Treasury and State reporting on Iran-linked militias and financial activity, and mandates certain frozen Iranian-related funds be transferred into the U.S. Victims of State Sponsored Terrorism Fund. The bill also asserts U.S. policy goals of denying Iran a nuclear weapon, rolling back Iranian proxy influence, supporting human rights, and treating any future agreement as a treaty requiring Senate ratification. Major provisions include codifying prior executive orders and sanction authorities, prohibiting many future sanctions relief actions absent a specific certification to Congress, banning certain presidential licensing/waiver authority beginning February 1, 2028, expanding Treasury identification/reporting thresholds and penalties, designating or preserving Foreign Terrorist Organization (FTO) actions (including for Ansar Allah/Houthis), requiring annual publication of Iran-linked militia lists, and authorizing increased rewards and a transfer of frozen funds to compensate victims of the October 7, 2023 attacks.
