Organisation number for main entity and for sub-entities
Which organisation numbers should you use in the a-melding?
Important information
From 2023, the a-ordning, vil stop using the terms legal entity's organisation number and enterprise number. The declarants legal entity is now referred to as the main entity end the enterprise they run is referred to as the sub-entity.
Use two organisation numbers to identify the party for which you are submitting the a-melding
In the a-melding, you identify the entity for whom you’re submitting the a-melding by stating the main entity's organisation number. 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. The main entity is the subject to the reporting obligation in the a-ordning scheme.
If you have employees, you must also state the organisation number for the 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. State the sub-entity's organisation number when reporting information about employment, income, deductions and employer's national insurance contributions.
If you only state the type of employment as pension or work without employment, or you do not state the employment at all, you can state the organisation for the main entity when specifying the sub-entity level in the a-melding.
Main entity
State the organisation number of the main entity in order to identify the party for which you are submitting the a-melding. This also applies to sole proprietorships.
All enterprises and associations that register in the Register of Legal Entities are assigned an organisation number. The entity that is identified by this organisation number is known as the main entity. The main entity is the declarant in the a-melding.
Don’t have a an organisation number? See the Brønnøysund Register Centrer and altinn.no for more information and application form.
Private individuals must use their national identity number
If you submit an a-melding as a private individual, you must use your national identity number in order to identify the declarant.
Sub-entity
State the organisation number for the sub-entity and link the employees to the sub-entity they work for.
Everyone who operates commercially and/or has employees, must have at least one sub-entity, identified by an organisation number for the sub-entity. The sub-entity is not independent. It must always be linked to a main entity. Under a main entity, there can be one or more sub-entities.
Make sure that the registration in the Register of Legal Entities is correct and report according to the same structure in the a-melding. Complete the registration in the Register of Legal Entities before you submit an a-melding.
Don't have an organisation number for the sub-entity? See the Brønnøysund Register Centrer and altinn.no for more information and an application form.
How to find the organisation number for your sub-entity
Most people engaged in business activity are assigned both an organisation number for the main entity and for the sub-entity. On the website for the Brønnøysund Register Centre you can find the organisation number for your sub-entity. Enter the main entity's organisation number in the field Find enterprise/company. At the bottom of the next page (the search result), you’ll find a link to the page which shows the sub-entity registered under the main entity.
Not yet been assigned an organisation number for the sub-entity
If you've applied for an organisation number for the sub-entity in the Register of Legal Entities, and you've not received it by the deadline for submitting the a-melding, you must delay the submission until you've been assigned the organisation number.
Once you have received an organisation number for the sub-entity, you must use this number instead.
Example with one sub-entity
A hair salon that intends to run a business in Bodø has registered in the Register of Legal Entities. It has been assigned an organisation number for the main entity and an organisation number for the sub-entity in Bodø.
The salon specifies the main entity's organisation number in order to identify the declarant in the a-melding.
It also states the organisation number for the sub-entity in Bodø and links information concerning the employees to this number.
Example with several sub-entities
A plumbing firm that intends to run a business in both Oslo and Halden has registered in the Register of Legal Entities. The firm has been assigned an organisation number for the main entity and two organisation numbers for the sub-entities, one for Oslo and one for Halden.
The plumbing firm specifies the organisation number for the main entity in order to identify the declarant when it submits a-meldings for Oslo and Halden.
It also states the organisation number for the sub-entity in Oslo and links information concerning the employees in Oslo to this number.
Correspondingly, it also states the organisation number for the sub-entity in Halden and links information concerning the employees in Halden to this number.
The firm reports information for both sub-entities in the same a-melding (recommended). It can also report information for the sub-entity in Oslo in one a-melding and information for the sub-entity in Halden in another a-melding.
