All foreign businesses in need of a Norwegian organisation number must register as a Norwegian registered foreign business (NUF).
Foreign businesses that are doing business operations in Norway are obliged to register in The Register of Business Enterprises.

It is the foreign business in the country of origin which is responsible for the business in Norway.
Frequently asked questions about Norwegian registered foreign business (NUF)
The fee for registration in the Central Coordinating Register for Legal Entities will be reduced when the initial registration is done at the same time as the registration in the Register of Business Enterprises.
On the page headed Duty to register in the Register of Business Enterprises for NUF you will find information about register requirements.
If you wish to make changes to the information registered on your NUF, you can in most cases do this by submitting an electronic version of the form Coordinated register notification. If there are changes or new information about the business in the country of origin, you cannot use an electronic form.
For businesses registered with the Register of Business Enterprises, it is not possible to use an electronic form if there is not registered, or reported, a general manager, a Norwegian representative, a board for the Norwegian business or a person with signature rights.
When you have sold goods or services for more than NOK 50,000 in the course of a twelve month period, you must register the business in the VAT Register.
You will find more information about the VAT Register with the Tax Administration.
NUF that carries out commercial activities in Norway, and is taxable to Norway according to Norwegian domestic legislation, has accounting obligation and an obligation to submit annual accounts to the Register of Annual Accounts.
If the NUF, which is registered in the Register of Business Enterprises, has no accounting obligation, they must report this in writing for each fiscal year to the Register of Annual Accounts. On the page headed Reporting obligations for Norwegian registered foreign businesses, you will find more information about accounting requirements.
NUF with an accounting obligation is required to undergo an audit starting from the subsequent fiscal year if they exceed any of the following three thresholds:
- NOK 7 million in operating revenue
- NOK 27 million in total assets
- an average of 10 full-time equivalents or more.
If the company falls below these threshold values and no longer wants to have an auditor, it can notify in the following financial year that the auditor will not continue.
You cannot directly register a conversion from NUF to limited company. You must therefore
- register the new limited company
- close down the NUF
In order for the conversion to be tax-free, the limited company must be established and a notification about this submitted to the Register of Business Enterprises during the period between 1 January and the end of June in the income year. Tax deductions and calculated employer’s contribution must be made no later than 1 July.
