Beneficial ownership and how it affects branches
A branch is not a legal entity in the same way that a limited company is, so the branch itself is not required to register beneficial ownership information with Bolagsverket. However, the foreign-based company which owns the branch may need to register if it can be classed as a foreign legal entity with activities in Sweden.
If the foreign company does register information, it should use the company name registered abroad and not the branch’s name or registration number.
Foreign companies based within the European Economic Area (EEA) do not need to register information in Sweden if they will be registering information in the beneficial ownership register of another EEA country.
