Beneficial Ownership
The natural persons who ultimately own or control a legal entity — under the US CDD Rule, any individual owning 25% or more of the equity, plus one individual with significant managerial control.

Why it matters
Opaque ownership is the mechanism behind most serious laundering through the regulated sector. Beneficial ownership work is both the most tedious and the most consequential part of entity onboarding, and it is a growing share of open KYC roles.
In practice
The CDD Rule sets an ownership prong (25% threshold) and a control prong (one individual with significant responsibility to control, manage, or direct). Separately, the Corporate Transparency Act created a federal beneficial ownership registry at FinCEN with its own reporting population and a legal history worth tracking, since its scope has been litigated and revised.
