Sub-entity

Last updated: 15 March 2024.

Would you like to know why you have two organisation numbers? It is because your enterprise has a sub-entity.

In addition to the enterprise’s organisation number your sub-entity has its own organisation number.

There are several reasons for why you need a sub-entity. You need it when you:

  • conduct business activity
  • report salary or remuneration in the a-ordning scheme

Even if you do not have employees today, or pay board remunerations, the sub-entity is all set if you need it in the future. You can see which sub-entities you have by looking at the service Information on organisations.

When should I use the sub-entity’s organisation number?

You use this when:

  • you report wages, remuneration and freelance in the a-ordning scheme
  • the Statistics Norway requests information
  • you have received a digital medical certificate
What is a main entity?

A main entity is a collective term for companies, associations, persons and others registered in the Central Coordinating Register for Legal Entities, and which is not a sub-entity.

The main entity is an enterprise at the highest level in the registration structure in the Central Coordinating Register for Legal Entities.

What is a sub-entity?

The sub-entity defines the activity operated by the main entity. A main entity can have one or several sub-entities. The sub-entities are not independent enterprises. They will always be connected to a main entity.

A sub-entity is an enterprise at the lowest level in the registration structure in the Central Coordinating Register for Legal Entities.

Statistics Norway decides which sub-entities that are to be registered, as well as classification of these. Registration and classification takes place according to international statistical standards.

A main entity may not refuse or require such registration.

Registration of multiple sub-entities

Multiple sub-entities are to be registered if one of the following terms are met:

  • Business activity is conducted in various branches. Each branch must employ at least 5 persons
  • Business activity is run with employees in several geographical locations

Different branches

Variuos branches mean that the activities fall under different industrial codes in accordance with the Standard for industrial grouping (SN2007)

Activities performed only to serve the primary activity of the main entity, should not be registered as a separate sub-entity. Examples of this may be administration, IT department and sale of self-produced goods. Such activities should only be registered as a separate sub-entity if it operates in another geographical location than the main entity’s primary activity takes place.

Multiple geographical locations

When the sub-entities are located at different addresses, this means that activity is conducted in several geographical locations. Entering different postal addresses is not sufficient to register a sub-entity.

For ambulatory activity, only permanently staffed branch offices and the like are registered. Examples of this are building and construction, transport and hiring of manpower, and temporary staff recruitment agencies.

Public administration

The general rules described above, also apply to public administration. Detailed regulations for registration of sub-entities in municipalities, county municipalities and health trusts are available at www.ssb.no under reporting, Kostra, Guidance.

How do I register several sub-entities?

If you are going to register multiple sub-entites, you need to fill in the Form for sub-entities –  activity at multiple addresses, and upload this as an attachment to the form Coordinated register notification in Altinn (tick for the enterprise to register one or multiple new sub-entities).

Aquisition and transfer of sub-entity

A sub-entity can be taken over or transferred from one main entity to another. In such cases, the sub-entity will retain its organisation number.

For a sub-entity to be regarded as taken over or transferred, the following conditions must apply:

  • The same activity continues, but with a different main entity as the new owner of the sub-entity
  • The activity continues in the same municipality as previously
  • As a rule, the necessary assets included in the activity must be transferred as a whole. Examples of this are raw materials, production equipment, inventory, contracts and employees.
How do I register transfer of a sub-entity?

This confirmation must be signed by the aquirer and documents that the transfer is correct. The attachment requirement will appear once you have filled out and checked the form.

The inbox in Altinn

Remember to clear the inbox of the sub-entity in Altinn before the transfer.

Sensitive information, such as medical certificates, ought to be stored in a separate case/filing system before the transfer is being registered. This prevents the acquirer from gaining access to sensitive information contained in the inbox of the sub-entity.

Number of employees

The Central Coordinating Register for Legal Entities contains information about number of employees for all employers registered in this register. The number of employees refers to active working conditions registered in the Aa-register of NAV.  All employers must report the working conditions every moth in the  form Aa-notification.

Enterprises with employees must have at least one sub-entity. The sub-entities are identified with a separate organisation number associatied with the main entity. The number of employees is connected to a sub-entity and comprises the number of unique individuals working for the sub-entity. If an individual has several employment connections related to the same enterprise, this individual is counted only once.

Information about number of employees is available, among other things, through the service Open data. You can choose whether to see the number of employees connected to one sub-entity, or the total number of employees for the main entity.
