The Beneficial Ownership Register is a statutory record maintained under the Companies Act 1981, listing all individuals who ultimately own or control more than 25% of shares or voting rights in a Bermuda entity. It is uploaded to Bermuda’s BOSS (Beneficial Ownership Secure Search) platform, accessible by the Bermuda Monetary Authority and law enforcement. Any change in beneficial ownership must be registered within 30 days. Failure to update carries penalties of BMD $5,000 per director for a first instance.
