18 steps to doing business in Norway
When must a foreign company register in Norway?
A foreign company must register in Norway as soon as it carries out business activities here. Some cases are clear-cut, such as winning a large construction contract or setting up a subsidiary, but many fall into gray areas that need a careful assessment.
- Carries out business activities in Norway, even on a small scale
- Has an employee working in Norway, including from a home office or an office hotel
- Hires out employees to work in Norway
- Wins a contract worth more than NOK 20,000 that results in activity in Norway
- Wins a contract in Norway but subcontracts the entire project back-to-back to another company
What are the registration options for foreign companies in Norway?
Most foreign companies choose between registering a NUF or setting up a Norwegian limited liability company (AS). The two are broadly similar for tax and VAT purposes. The real differences are in compliance and reporting obligations, and in how long you plan to stay.
A sole proprietorship is set up by an individual, not a company, and is mainly relevant for foreign freelancers and self-employed individuals working in Norway.
The right choice usually depends on your plans:
- NUF (Norwegian-registered foreign company): a registration of the foreign company itself. It suits short-term projects and is easy to set up and close down.
- LLC (limited liability company, AS): a Norwegian subsidiary. It suits a long-term presence, such as leasing an office or employing staff on an ongoing basis.

- 02 LLC EXPLAINED
- 03 SP EXPLAINED
What is a Norwegian-registered foreign company?
The official translation of “NUF” is “Norwegian-registered foreign company”, but the term “Norwegian branch of a foreign company” is also used. Experience has shown that the term “branch” can confuse some foreign companies. It is important to understand that the NUF is not a separate legal entity. The NUF is merely a formal registration of the main company or “headquarters” in a foreign country. The formal registration says little about the foreign company's tax and VAT position.

What is a limited liability company?
A limited liability company (LLC), in Norway known as "AS" or "aksjeselskap" is a legal business structure where the owners' liability is limited to their share capital. This means the shareholders are not personally responsible for the company's debts beyond their invested amount. Running a limited liability company (LLC) in Norway comes with several legal and administrative responsibilities that must be managed to stay compliant. While Norway does not require a company secretary by law, these duties are often carried out by a company secretary function.
Key features include:
- A minimum share capital of NOK 30,000.
- A board of directors is required, though small companies may not need a full board.
- The company must be registered with Brønnøysundregistrene (the Norwegian Register of Business Enterprises).
This structure is popular for businesses seeking limited personal financial risk and a formal legal framework.
What is a sole proprietorship?
A sole proprietorship in Norway (called "enkeltpersonforetak") is a business owned and operated by a single individual. It is not a separate legal entity, meaning the owner is personally liable for all business debts and obligations. It's easy and inexpensive to set up, has low administrative requirements, and is commonly used by freelancers and small business owners. Profits are taxed as part of the owner's personal income.
LLC vs. NUF vs. SP
This table only shows a selection of the requirements for operating a company in Norway. To get a complete overview, and understand what applies to your specific business, a thorough review of your company is necessary.What digital access does a foreign company get after registrering in Norway?
After the NUF registration, the foreign company will obtain a Norwegian organization number, which means that the company will obtain access to;
- Altinn – the Norwegian log-in solution for public services, and
- The electronic portals of the Norwegian Tax Authorities.
These accesses are critical to be compliant with Norwegian reporting responsibilities.
When does a foreign company need to register for VAT in Norway?
A foreign company must register for VAT once its sales in Norway exceed NOK 50,000 over a 12-month period. VAT often needs attention first, because it affects your costs from the very first purchase. Planning before operations start makes it easier to recover input VAT and avoid costly mistakes.
Key VAT points for foreign companies:
- The standard VAT rate is 25%, and most goods and services are subject to VAT
- Registered companies can reclaim input VAT on business purchases
- VAT returns are filed electronically every two months
- Importing goods triggers import VAT
- Registration may be required even without a physical presence in Norway
What is the OAR reporting obligation for foreign companies?
Assignments in Norway worth more than NOK 20,000 must be reported to the Norwegian Tax Administration through the Assignment and Employee Register (OAR). The client and the foreign contractor each have their own reporting duty. Late or missing reports can lead to significant penalties.
Who reports what:
- RF-1199: the client reports the contract, including dates, contract value, and type of contract
- RF-1198: the foreign contractor reports every employee working on the assignment
- Deadline: no later than the 5th of the month after the assignment starts
- The type of contract, and whether construction or assembly work takes place, affects the tax and VAT position of both parties
What is the difference between a genuine subcontract and hired labor in Norway?
When reporting an assignment in Norway, the parties must classify the contract as either hired labor or a genuine subcontract. The classification affects the corporate tax position of the foreign company, the personal tax of its employees, and VAT. The line between the two is not always clear, so the actual terms and practice of the contract matter more than its title
→ Why contract classification is key to staying compliant in Norway
The key difference:
- Hired labor: the client directs the workers, payment is usually based on hours or days, and the foreign company bears no responsibility for the result. The client pays for labor.
- Genuine subcontract: the foreign company delivers a defined result, directs its own employees, provides its own tools, and bears the economic risk. Payment is usually a fixed sum. The client pays for a result.
What do foreign workers need to work legally in Norway?
EU/EEA citizens can work in Norway without a permit, but must register with the police if they stay longer than three months. Non-EU/EEA workers, including British nationals, generally need a residence permit from UDI before they start work. Processing often takes two to four months in practice, so immigration planning should start as early as the tendering stage.
Key points to plan for:
- Work permits are tied to a specific employer and position, so moving workers between projects can require a new application
- Your choice of NUF or AS can affect which permit routes are available
- Under the technical expert rule, specialists can work up to 90 days without a permit, but only if the authorities are notified before arrival
- All foreign workers must attend an ID check at the tax office when they start work in Norway

Are HSE cards required to work on Norwegian construction sites?
Yes. Workers on Norwegian building and construction sites must carry a valid HSE card (HMS-kort), which serves as both ID and site access pass. Workers without one can be refused entry, causing delays and possible contract penalties.
The card can only be ordered once the company is registered in Norway and the worker has a D-number. Counting from registration, the whole process can take five weeks or more, so plan for it before start dates are confirmed..
Do foreign employees pay social security in Norway?
In principle, yes. A foreign company working in Norway and its employees are liable to contribute to the Norwegian National Insurance Scheme. In most cases, these contributions can be avoided with the right documentation. For EU/EEA workers, that's an A1 form confirming they're still covered by social security in their home country.
What's at stake:
- Employer contribution of 14.1% and employee contribution of 7.6% of salary
- A valid A1 form generally also exempts the employer from setting up a Norwegian occupational pension scheme
- British workers can still obtain an A1 form after Brexit
- Other non-EU/EEA workers are covered from day one, unless a bilateral agreement or an exemption from NAV applies
What must foreign employers withhold and report in Norway?
A foreign company must deduct advance tax from the salaries of employees working in Norway, and report salary and benefits monthly through the A-melding (A-report). Without a tax deduction card, which workers get at their ID check, the employer must deduct 50%. The reporting obligation applies even if the employee ends up paying no Norwegian tax.
Key points for foreign employers:
- An exemption from advance tax deduction can be applied for, and Nordic workers can use the NT1 form
- The A-melding is due by the 5th of the month after salary is paid
- From 2026, withheld tax must be paid no later than the first working day after salary is paid
- Late or incorrect A-meldings can trigger daily enforcement fines
When is a foreign company taxable in Norway?
A foreign company is, as a starting point, liable to Norwegian tax on income from business activities in Norway. The corporate tax rate is 22%. Under most tax treaties, however, Norway can only tax profits attributable to a permanent establishment (PE) in Norway. This makes the PE assessment the key tax question for foreign companies, and it should be made before the project starts.
A permanent establishment typically arises through:
- A fixed place of business, such as an office or workshop. Six months is a common rule of thumb, but there is no fixed threshold.
- A construction, installation or assembly project lasting longer than the treaty threshold, usually 12 months but six months in some treaties.
- A dependent agent who regularly concludes contracts in Norway on the company's behalf.
Hiring out personnel does not usually create a permanent establishment, but time spent on site by subcontractors can count toward the project period.
How are foreign employees taxed in Norway?
Foreign employees are, as a starting point, taxable in Norway on income from work carried out here. The tax treaty between Norway and the employee's home country determines which country has the right to tax. The outcome depends largely on the type of contract and whether the company has a permanent establishment in Norway.
Key starting points:
- Hired labor: employees are generally taxable in Norway from day one
- Permanent establishment: employees are generally taxable on income related to it
- No permanent establishment: under most treaties, employees are not taxable in Norway unless they stay more than 183 days in a 12-month period
- PAYE: most foreign workers are taxed at a flat 25%, or 17.4% with a valid A1 form, if they earn less than NOK 725,050 (2026)

A foreign company that carries out business activities in Norway and is taxable here under Norwegian law is generally subject to Norwegian accounting requirements. Companies registered in the Register of Business Enterprises must also file annual accounts, and late filing can lead to significant fees.
Companies registered only in the Central Coordinating Register for Legal Entities generally do not have to file annual accounts.
A Norwegian auditor is generally required if the company has:
- Operating revenues of at least NOK 7 million
- A balance sheet total of at least NOK 27 million, or
- An average of at least 10 full-time employees
What labor law rules apply to foreign companies in Norway?
Norwegian employment law gives employees extensive protection, and it applies to work carried out in Norway regardless of where the employer is based. The Labour Inspection Authority regularly inspects construction sites, with a particular focus on social dumping, and Norwegian contractors often require subcontractors to document compliance. Employment terms should be reviewed before work starts, and ideally already when budgeting the project.
Key areas for foreign employers:
- Working hours: normal limits are 9 hours per day and 40 hours per week, and rotation schemes must be set up correctly
- Minimum wage: there is no general minimum wage, but minimum rates apply in certain sectors, including construction
- Collective agreements: the client contract may require compliance with a collective agreement
- Staffing agencies: foreign staffing agencies must be authorized, and hiring from them for construction work is prohibited in parts of Eastern Norway

What are the HSE requirements for foreign companies in Norway?
HSE is a major focus for Norwegian companies when they hire foreign contractors. The employer must make sure the working environment is fully satisfactory, and the parent company's management may keep overall responsibility even when the Norwegian activity is delegated to a local manager. HSE should be in place before employees arrive, not when the first inspection takes place.
Joint inspections by several agencies are common on larger sites, and companies must provide extensive documentation at short notice .
What foreign companies should have in place:
- An HSE plan and, where relevant, a Safe Job Analysis (SJA), which are standard requirements in larger contracts
- A clear line of responsibility, with a local manager who has the competence and authority to act
- Routines for reporting serious accidents to the Norwegian authorities
- Membership of an approved occupational health service (BHT), where required
Do foreign companies need special registration for electrical work in Norway?
Companies carrying out work on electrical installations in Norway may need to register in the Elvirksomhetsregisteret and appoint a professionally responsible person (faglig ansvarlig). The starting point is that the company that actually performs the electrical work must register. Taking contractual responsibility for the electrical scope does not, in itself, trigger registration.
→ Registration and approval guide for foreign electrical workers
Plan for this before signing the contract:
- Identify which activities count as electrical work, and who will perform them
- Foreign qualifications may need approval from DSB, which can take four to six months
- Commissioning and testing after connection to the power supply may count as electrical work
- Using a registered Norwegian electrical contractor can remove the need to register
What else should foreign companies plan for in Norway?
Beyond registration, tax and employment, several other issues can affect a project in Norway, depending on the industry, customer and size of the assignment. Some are legal requirements, while others are commercial. Not every issue applies to every company, but identifying the relevant ones before the project starts helps avoid delays and unexpected costs.
Issues to have on your radar:
- Quality schemes such as Central Approval and StartBANK are not legal requirements, but customers increasingly use them to prequalify suppliers
- NS standard contracts (NS 8405, 8406, 8407) allocate risk differently from what many foreign contractors expect
- The Transparency Act can apply indirectly, as large Norwegian customers require supply chain information from their suppliers
- Customs rules for temporary imports of equipment and tools
- Opening a Norwegian bank account can take time because of anti-money laundering checks
- Occupational injury insurance must cover accidents in Norway

How long does it take to start operating in Norway?
Norwegian compliance is, above all, a matter of timing. Registration, work permits, D-numbers, HSE cards, electrical registration, VAT registration and social security exemptions all take time, and several steps can't begin until an earlier one is complete. For a large construction project, planning should typically start six to eight months before work begins.
Typical lead times:
- NUF registration: 3–4 weeks
- Work permits: often two to four months in practice
- Electrical approval (DSB): four to six months in complex cases
- HSE cards: five weeks or more, counting from registration
