In this lesson, ComplyPro focuses on certification forms for financial institutions. It is emphasized that each institution can use its own self-certification form template, but it should gather mandatory data outlined in the Common Reporting Standard (CRS) commentary, following local regulations and guidance. An example of an individual self-certification form from the OECD is provided, which collects information on the account holder’s tax residency for CRS compliance. The form remains valid unless there are changes in circumstances that render it incorrect or incomplete, and separate forms are required for joint or multiple account holders.
