Congressional Budget Office Cost Estimate: S. 722, Countering Iran's Destabilizing Activities Act of 2017 [open pdf - 17KB]
From the Document: "S. 722 would require the President to impose sanctions on people and entities involved with Iran's ballistic missile program and weapons proliferation activities, as well as on the Iranian Revolutionary Guards Corps. In addition, it would authorize the President to impose sanctions on people and entities responsible for human rights violations in Iran. Sanctions imposed under the bill would include freezing assets that fall under U.S. jurisdiction, prohibiting transactions with sanctioned persons, and denying entry into the United States. Finally, S. 722 would require periodic reports to the Congress on the implementation of the bill and related matters. Implementing S. 722 would increase administrative costs at the Department of State and the Department of the Treasury. Based on limited information from the Administration and the costs of implementing similar legislation, CBO [Congressional Budget Office] estimates that under S. 722 the departments would require additional appropriations of $2 million a year. In total, and incorporating the effects of inflation, CBO estimates that implementing those provisions would cost $10 million over the 2018-2022 period, assuming appropriation of those estimated amounts. Enacting S. 722 would increase both the number of people who would be denied visas by the Secretary of State and the number who would be subject to civil or criminal penalties for violating sanctions."
