Iran Sanctions Accountability Act of 2023

Removed the prohibition on facilitating 'the purchase of goods or services involving a person designated for the imposition of sanctions pursuant to the International Emergency Economic Powers Act (IEEPA)' from both the regulatory requirement and the rule of construction. The list of prohibited facilitation activities now covers only terrorism support and WMD proliferation.

Added a new sunset trigger: the section expires 30 days after the Secretary of the Treasury reports to Congress that reasonable grounds do not exist for concluding Iran is a jurisdiction of primary money laundering concern. This provides an additional path for expiration beyond the existing 7-year limit and terrorism cessation finding.

Changed the presidential reporting requirement from annual reports indefinitely ('each year thereafter') to biennial reports for a limited period ('every 2 years thereafter for 6 years'), significantly reducing the ongoing oversight obligation.

Changed statutory citations from bare U.S. Code references (e.g., 'section 8803(e) of title 22') to original NDAA section numbers with U.S. Code references in parentheses (e.g., 'section 1244(e) of the National Defense Authorization Act for Fiscal Year 2013 (22 U.S.C. 8803(e))'), improving traceability to the source legislation.
