Treasury Launches Consolidated CFIUS Website With New Tools and Guidance
Transaction parties and advisors involved in cross-border M&A or U.S. real estate deals subject to CFIUS jurisdiction must review the new consolidated CFIUS.gov website, which introduces a pre-filing consultation portal, a public risk matrix, and updated filing guidance that can streamline review timelines and reduce processing delays.
On July 29, 2026, the U.S. Department of the Treasury, acting as CFIUS Chair, launched a redesigned, consolidated CFIUS website (CFIUS.gov) that centralizes previously dispersed guidance and introduces several new resources for transaction participants. Key features include an online pre-filing consultation portal integrated with CFIUS’s Case Management System, allowing parties to engage with staff at least five business days before submitting a declaration or notice; a public CFIUS Risk Matrix that outlines the Committee’s analytical framework across eight national security risk categories, including associated threats, vulnerabilities, consequences, and representative mitigation measures; and comprehensive filing process guidance that clarifies the declaration-versus-notice decision, identifies common causes of processing delays, and recommends voluntary supplemental materials to include with initial filings. The website also hosts dedicated initiative pages for the Known Investor Program, Investment Security Technology Initiative, and Strategic Vendor Program. Parties should incorporate early use of the consultation portal and risk matrix into deal planning to proactively address potential national security concerns, minimize follow-up information requests, and avoid unnecessary conversion of declarations to full notices.
