Solidify Iran Sanctions Act of 2025

The bill would amend the Iran Sanctions Act of 1996 by removing the law's sunset (automatic expiration) provision. Under the current law, the sanctions regime requires periodic reauthorization to stay in force; this bill would eliminate that expiration mechanism entirely, making the law permanent. The sanctions themselves — which require the President to impose penalties on individuals or entities engaged in transactions tied to Iran's energy sector or Iran's efforts to acquire chemical, biological, nuclear, or conventional weapons — would remain in place without any future congressional action needed to keep them alive.

The bill does not change the substantive requirements of the Iran Sanctions Act itself, modify who is sanctioned, alter the types of covered transactions, or create any new sanctions authority. It is a single structural amendment removing one subsection.

The President and executive branch agencies responsible for implementing and enforcing the Iran Sanctions Act, including the decision-making process around periodic reauthorization. Foreign individuals, companies, and entities currently subject to or at risk of Iran sanctions would no longer benefit from any uncertainty created by the law's expiration cycle.

By removing the sunset clause, Congress would no longer need to periodically reauthorize the Iran Sanctions Act for it to remain in effect. This closes a potential gap during which the sanctions framework could lapse — whether due to legislative inaction or political disagreement — and signals a permanent U.S. commitment to economic pressure on Iran over its weapons programs and support for terrorism.
