Isle of Man FSA Updates AML/CFT Handbook With New Sanctions and HNW Guidance
The Isle of Man Financial Services Authority (IOMFSA) updated its Anti-Money Laundering and Countering the Financing of Terrorism Handbook on 24 August 2026, adding and revising guidance across several areas that regulated entities and designated businesses are expected to use when managing money-laundering and terrorist-financing risk.
The Authority said the revisions include updated guidance on de-risking, new guidance on complex structures and high-net-worth individuals, and additional guidance on source of funds, source of wealth and enhanced customer due diligence (ECDD). The revised Handbook also adds guidance on commercially exposed persons and creates a new chapter dedicated to sanctions compliance.
The Handbook sits alongside the Authority’s Supplemental Information Document and sector-specific AML/CFT guidance. IOMFSA said these materials form part of its outreach and engagement programme to help firms meet their AML/CFT obligations, and encouraged regulated entities and designated businesses to review the revised material and take appropriate measures to mitigate their ML/TF risks.
Broader focus on risk context
The changes widen the practical risk factors addressed in the Handbook beyond conventional customer identification. Complex structures, HNW relationships, source-of-funds and source-of-wealth analysis, ECDD and sanctions controls all require firms to understand why a relationship or transaction is structured in a particular way and whether the available evidence is consistent with the customer’s profile and stated activity.
The update is supervisory guidance rather than a new standalone AML/CFT law. Its significance is that it gives Isle of Man firms a more detailed reference point for how the regulator expects existing obligations to be applied in higher-risk and more complex situations.
