Company accounting in Norway

Laws regulating accounting in Norway

Accounting in Norway is regulated by a clear and relatively strict legal framework designed to ensure transparency, comparability and reliability of financial information. Every business operating in Norway, including foreign-owned companies, must follow these rules from the moment it starts economic activity.

Key legal acts

The most important laws governing accounting and financial reporting in Norway are:

• Accounting Act (Regnskapsloven) – sets out who is obliged to keep accounts, how accounting records should be kept, what principles must be followed, and what financial statements must contain.
• Bookkeeping Act (Bokføringsloven) – regulates the practical side of bookkeeping, including documentation requirements, deadlines for recording transactions, storage of accounting data and rules for electronic records.
• Companies Act (Aksjeloven / Allmennaksjeloven) – defines the framework for limited liability companies (AS/ASA), including capital requirements, corporate governance and obligations related to annual accounts and audits.
• Tax Administration Act (Skatteforvaltningsloven) and related regulations – specify how accounting data is used for tax purposes, deadlines for reporting and the powers of the tax authorities.

Who is subject to Norwegian accounting rules

As a general rule, all entities engaged in business activity in Norway are subject to the Accounting Act. This includes:

• Norwegian limited liability companies (AS)
• Branches and subsidiaries of foreign companies
• Sole proprietorships (enkeltpersonforetak) above certain income thresholds or with VAT registration
• Partnerships and other legal entities conducting business

Smaller entities may benefit from simplified rules, but they are still required to keep orderly accounts and retain documentation in line with the Bookkeeping Act.

Fundamental accounting principles

Norwegian accounting law is based on generally accepted accounting principles (god regnskapsskikk). Among the most important are:

• Accrual basis – income and expenses are recognised when they are earned or incurred, not when cash is received or paid.
• Going concern – the company is assumed to continue its operations, unless there is evidence to the contrary.
• Consistency – the same principles and methods should be applied from year to year for comparability.
• Prudence – assets and income must not be overstated, and liabilities and expenses must not be understated.
• Documentation – all entries in the accounts must be supported by proper and verifiable documentation.

Norwegian GAAP and IFRS

Most Norwegian companies prepare their financial statements in accordance with Norwegian GAAP, which is based on the Accounting Act and Norwegian accounting standards. Larger companies and listed entities may be required to use IFRS (International Financial Reporting Standards). The choice of framework affects the format of the annual accounts, valuation methods and disclosure requirements.

Documentation and retention obligations

The Bookkeeping Act requires that all transactions are documented and recorded within specific deadlines. Typical source documents include invoices, contracts, bank statements, cash reports and payroll records. Accounting material must generally be stored for several years, often in Norway, and must be accessible for inspection by the tax authorities and other supervisory bodies.

Supervision and sanctions

Compliance with accounting regulations is monitored by the Norwegian Tax Administration (Skatteetaten), the Register of Company Accounts (Regnskapsregisteret) and, for certain entities, the Financial Supervisory Authority of Norway (Finanstilsynet). Failure to comply with the Accounting Act or Bookkeeping Act can lead to fines, compulsory corrections, loss of registration, and in serious cases, personal liability for the company’s management.

Understanding the laws regulating accounting in Norway is essential for correct bookkeeping, tax compliance and safe business growth. Professional support from an accountant familiar with Norwegian regulations helps minimise risk and ensures that your company meets all statutory requirements.

Accounting accounts

In Norway, every business is required to keep its accounts using a structured and transparent chart of accounts. This system ensures that all income, costs, assets and liabilities are recorded in a consistent way and can be easily checked by the authorities. Properly set up accounting accounts are the foundation for correct bookkeeping, tax reporting and financial control in your Norwegian company.

Norwegian chart of accounts and account classes

Most companies in Norway use the standard Norwegian chart of accounts based on the Norwegian Accounting Act and common industry practice. Accounts are grouped into main classes, which makes it easier to understand the financial situation of the company:

• Class 1 – Assets (bank accounts, receivables, inventory, fixed assets)
• Class 2 – Equity and liabilities (share capital, loans, tax liabilities)
• Class 3 – Operating income (sales of goods and services, other income)
• Class 4 – Cost of goods sold and direct costs
• Class 5 – Payroll and personnel costs
• Class 6 – Other operating costs (rent, office expenses, insurance)
• Class 7 – Production and project-related costs
• Class 8 – Financial income and expenses (interest, currency differences)

Within each class, accounts are divided into more detailed account numbers. This structure allows you to track exactly where the money comes from and how it is spent, which is crucial both for management decisions and for compliance with Norwegian regulations.

Standard accounts vs. customised accounts

Norwegian law does not force you to use one specific chart of accounts, but the standard Norwegian chart of accounts is strongly recommended. It is recognised by accountants, auditors, banks and the Norwegian Tax Administration, and it simplifies reporting in systems such as Altinn.

At the same time, the chart of accounts can be adapted to the needs of your business. You can add new sub-accounts or rename existing ones, as long as the overall structure remains logical and consistent. For example, a construction company may create separate accounts for different projects, while a consulting firm may focus on separating income and costs by client or service type.

Link between accounts, VAT and tax reporting

Correct use of accounting accounts is essential for proper VAT and tax reporting in Norway. Each transaction must be posted to the right account and, when relevant, with the correct VAT code. This ensures that:

• sales and purchases are correctly included in the VAT return
• deductible costs are clearly separated from non-deductible expenses
• payroll, employer contributions and holiday pay are properly recorded
• year-end financial statements and tax returns are accurate and complete

Errors in account selection can lead to incorrect VAT calculations, underpayment or overpayment of tax and potential penalties from the Norwegian Tax Administration.

Practical examples of accounting accounts

To illustrate how accounting accounts work in practice, here are some typical examples used by companies in Norway:

• Bank account – asset account for the company’s main bank account
• Accounts receivable – asset account for unpaid customer invoices
• Sales domestic – income account for sales within Norway
• Purchase of goods – cost account for goods bought for resale
• Rent of premises – cost account for office or warehouse rent
• Salaries – cost account for gross wages to employees
• Employer’s social security contributions – cost account for mandatory employer contributions
• Interest expenses – financial cost account for interest on loans and credit

Using clear and consistent accounts like these makes it easier to analyse profitability, control costs and prepare budgets.

Digital accounting systems in Norway

Most Norwegian companies use digital accounting systems that already include a standard chart of accounts adapted to Norwegian rules. These systems often integrate with banks, invoicing tools and payroll systems, which reduces manual work and the risk of errors. When setting up your company, it is important to choose an accounting system that:

• supports the Norwegian chart of accounts and VAT rules
• is compatible with Altinn and other public portals
• allows easy reporting to your accountant or auditor
• can be adapted to the specific needs of your business

Why professional support with accounting accounts matters

For many foreign entrepreneurs and small business owners, the Norwegian chart of accounts and local accounting rules can be complex. Professional support from an accountant who knows Norwegian regulations helps you:

• set up the right accounts from the start
• avoid typical mistakes in VAT and tax reporting
• ensure that your bookkeeping meets the requirements of the Norwegian Accounting Act
• obtain clear financial reports for management, banks and authorities

A well-structured system of accounting accounts is not only a legal requirement in Norway; it is also a powerful tool for controlling your business and making informed decisions about its future.

Invoicing

In Norway, invoicing is strictly regulated and forms a key part of correct company accounting. Every business that sells goods or services must issue invoices that meet the requirements of the Norwegian Bookkeeping Act and VAT regulations. Proper invoicing is essential not only for tax control, but also for maintaining transparent and reliable accounts.

Mandatory elements of a Norwegian invoice

To be valid for accounting and VAT purposes, an invoice issued in Norway must contain specific information. Missing or incorrect data can lead to rejected deductions, additional controls or penalties.

• Full name and address of the supplier (as registered in the Brønnøysund Register Centre)
• Organisation number with the “MVA” suffix if the company is VAT-registered (for example: 999 999 999 MVA)
• Full name and address of the customer
• Unique, consecutive invoice number
• Invoice date (date of issue)
• Date of delivery of goods or services if different from the invoice date
• Clear description of the goods or services supplied
• Quantity and unit price
• Net amount excluding VAT, VAT rate and VAT amount
• Total amount to be paid, including VAT
• Currency used on the invoice
• Payment terms and due date

If the company is not registered for VAT, the invoice must not show VAT and should not contain the “MVA” suffix after the organisation number.

Electronic invoicing and formats

Electronic invoicing is widely used in Norway and is often required when dealing with public sector entities. Many companies also prefer e-invoicing for efficiency and better control of cash flow.

• EHF invoices – the standard electronic format for invoicing public entities and many private companies. EHF invoices are sent system-to-system and must meet specific technical and content requirements.
• PDF invoices – commonly used in B2B and B2C relations, but they are not considered structured e-invoices in the same way as EHF.

Regardless of the format, the content of the invoice must comply with Norwegian bookkeeping and VAT rules. Companies should use accounting or invoicing systems adapted to Norwegian regulations to avoid errors.

VAT rules on invoices

Businesses registered in the VAT register must charge VAT on taxable sales and show it clearly on the invoice. Different VAT rates may apply depending on the type of goods or services. If several VAT rates are used, they must be shown separately with the corresponding amounts.

In some cases, sales can be exempt from VAT or outside the scope of Norwegian VAT (for example, certain exports). In such situations, the invoice should include a short explanation or reference to the legal basis for the exemption.

Language, currency and foreign customers

Invoices in Norway can be issued in Norwegian or English, and in other languages if both parties understand them. The currency can also be freely chosen, but for accounting and tax purposes the amounts must be converted to NOK in the company’s accounts.

When invoicing foreign customers, it is important to correctly determine the place of supply and VAT treatment. Export of goods and certain services may be zero-rated, but the invoice and documentation must clearly show that the conditions for zero rating are met.

Numbering, corrections and credit notes

Invoice numbers must be consecutive and follow a logical sequence. Gaps or duplicated numbers can raise questions during a tax audit. If an invoice contains an error, it should not be deleted or overwritten. Instead, a correcting document must be issued:

• Credit note – used to reduce or cancel a previously issued invoice, for example in case of returns, discounts or mistakes.
• Corrective invoice – used when the original invoice needs to be adjusted upwards or when important information must be corrected.

Credit notes and corrective invoices must refer to the original invoice number so that the transaction history is clear and traceable.

Retention and documentation requirements

All issued and received invoices must be stored in accordance with Norwegian bookkeeping rules. The general retention period is several years, and documents must be kept in a way that ensures integrity, accessibility and readability throughout the entire period. Electronic storage is allowed, provided that the system secures the data and allows quick retrieval in case of control.

Correct invoicing in Norway is not only a formal obligation, but also a practical tool for managing cash flow, monitoring receivables and ensuring compliance with tax and accounting regulations. Using professional accounting support and compliant invoicing systems significantly reduces the risk of errors and financial penalties.

Company documentation

Proper company documentation is a key element of accounting in Norway and a frequent focus during tax and control checks. Every business is required to keep clear, traceable and up-to-date records that show all income, costs, assets, liabilities and equity. Good documentation not only ensures compliance with Norwegian law, but also makes it easier to manage cash flow, plan taxes and make business decisions.

What documents must a Norwegian company keep?

Norwegian regulations require that all transactions affecting the company’s accounts are supported by verifiable documentation. In practice, this means keeping at least the following:

• Sales invoices and credit notes issued to customers
• Purchase invoices and receipts from suppliers
• Bank statements and confirmations from Norwegian and foreign bank accounts
• Cash register reports and daily cash summaries (if you use cash or a POS system)
• Payroll documentation: payslips, employment contracts, timesheets, holiday pay calculations
• Agreements with clients and subcontractors, including framework contracts and annexes
• Loan agreements, leasing contracts and other financing documentation
• Documentation of fixed assets: purchase contracts, depreciation schedules, sale or scrapping documents
• VAT documentation: VAT returns, VAT reports, import VAT documents (toll declarations)
• Correspondence with authorities: Skatteetaten, NAV, Brønnøysundregistrene and others

Formal requirements for documentation

To be accepted for accounting and tax purposes, documentation must meet certain formal standards. Each document should clearly show who issued it, who it concerns and what the transaction is about. As a rule, the following information is required:

• Date of issue and date of the transaction
• Names and organisation numbers of the parties (where applicable)
• Clear description of the goods or services
• Quantity, unit price and total amount
• Currency and applicable VAT rate(s)
• Payment terms and due date

Electronic documentation is fully accepted in Norway, provided it is stored securely, is complete and can be presented to the authorities on request. Scanned documents are allowed, but the scans must be readable and identical to the original.

Retention periods and storage method

Norwegian law sets strict rules for how long company documentation must be kept. In most cases, accounting records must be stored for at least five years from the end of the financial year. Some types of documentation, such as information related to real estate or major investments, may have longer retention requirements.

Documentation can be stored electronically or on paper. Many companies choose digital archiving because it simplifies searching, backup and cooperation with the accountant. Regardless of the form, documentation must be:

• Organised in a logical and traceable way
• Protected against loss, damage and unauthorised access
• Available in Norway and ready to be presented during a control

Documentation and internal control

Well-structured documentation is an important part of internal control in a Norwegian company. Clear procedures for receiving, approving and archiving documents reduce the risk of errors, fraud and missed deadlines. It is good practice to define who in the company is responsible for:

• Collecting and forwarding documents to the accountant
• Approving purchases and contracts
• Checking that invoices match deliveries and agreements
• Monitoring payment deadlines and reminders

For growing companies, it is often worth implementing simple digital tools for document flow and approval. This makes cooperation with the accounting office more efficient and helps keep the accounts up to date.

Why proper documentation matters for taxes and reporting

All key reports in Norway – annual accounts, tax returns, VAT returns, employer reports and others – are based on the company’s documentation. If documents are incomplete or incorrect, the risk of errors in reporting increases, which can lead to additional tax assessments, interest and penalties.

Correct documentation allows the company to:

• Prove business costs and reduce taxable profit
• Deduct input VAT correctly
• Document salaries and employer contributions
• Show the real financial situation of the business to banks and investors

Professional support in organising and maintaining company documentation helps ensure that the business meets Norwegian legal requirements, minimises tax risk and has reliable financial information for everyday management.

Taxation

Norwegian taxation is based on transparency, electronic reporting and close cooperation between companies and the tax authorities. Understanding the main types of taxes and reporting duties is essential for running a compliant and efficient business in Norway.

Main types of taxes for companies

Most companies operating in Norway are subject to corporate income tax on their profits. The standard corporate tax rate is set nationally and applies to limited liability companies, branches of foreign companies and most other legal entities. Sole proprietorships are taxed differently, as business profit is treated as the owner’s personal income.

In addition to income tax, many businesses must register for and charge value added tax (VAT). VAT applies to most goods and services supplied in Norway once the company exceeds the mandatory registration threshold. Some sectors, such as health services, education and certain financial services, are exempt or outside the scope of VAT, but the rules are detailed and should be checked carefully for each activity.

VAT registration and reporting

When a company’s taxable turnover passes the statutory limit within a 12‑month period, it must register in the VAT Register. After registration, the business must add VAT to its invoices, keep VAT-compliant records and submit periodic VAT returns through the electronic reporting system.

VAT returns are usually filed every two months, although some smaller businesses may be allowed different reporting intervals. The company must report output VAT on sales and input VAT on purchases, and pay the net amount due to the tax authorities by the deadline. Late filing or late payment can result in penalties and interest.

Advance tax payments and annual settlement

Norwegian companies pay income tax in advance based on estimated profits. During the year, the company makes instalment payments, and after the annual accounts and tax return are submitted, the final tax is calculated. Any difference between advance payments and the final tax liability is either refunded or must be paid as an additional settlement.

The tax return and annual accounts are filed electronically. Accurate bookkeeping, timely closing of the accounts and correct classification of income and expenses are crucial to avoid corrections and additional tax assessments.

Employer taxes and payroll obligations

Companies with employees must withhold income tax from salaries and pay it to the tax authorities on behalf of the employees. In addition, employers pay employer’s National Insurance contributions, which are calculated as a percentage of gross wages. The rate depends on the geographical location of the company and is set by law.

All payroll transactions must be reported through the official reporting system on a regular basis. This includes salaries, benefits in kind, reimbursements and employer contributions. Proper payroll routines and documentation are essential to remain compliant and to ensure that employees are taxed correctly.

Withholding tax and cross-border situations

Foreign companies operating in Norway, or Norwegian companies paying for certain services or royalties abroad, may be subject to withholding tax rules. Norway has an extensive network of tax treaties that can reduce or eliminate withholding tax in cross-border situations, but the conditions must be documented and applied correctly.

Branches and subsidiaries of foreign companies are generally taxed on income attributable to their Norwegian activities. Determining the correct taxable presence, profit allocation and documentation is particularly important in international structures.

Tax deductions and documentation

Norwegian tax rules allow deductions for business-related costs that are necessary to generate income. Typical deductible expenses include rent, salaries, social costs, professional fees, travel and certain investments. Some costs are only partly deductible or subject to special limitations, for example representation expenses or private use of company assets.

To claim deductions, the company must keep proper documentation such as invoices, contracts and travel records. All documentation must be stored in accordance with Norwegian bookkeeping regulations and be available in case of a tax audit.

Compliance, audits and penalties

The Norwegian Tax Administration uses electronic data, risk analysis and random checks to monitor compliance. Companies may be selected for tax audits, during which the authorities review accounts, contracts and other documentation. If errors are found, the company may be required to correct its tax returns and pay additional tax, interest and in some cases penalties.

Working with an accountant who understands Norwegian tax law and reporting systems helps reduce risk, optimise the tax position within legal limits and ensure that all deadlines are met. Proper tax planning and continuous follow-up are key elements of successful company accounting in Norway.

Types of companies in Norway

Choosing the right legal form is one of the most important decisions when starting a business in Norway. The company type affects your personal liability, tax rules, reporting obligations and how easy it is to bring in investors or sell the business later. Below is an overview of the most common types of companies in Norway and when they are typically used.

Sole proprietorship (Enkeltpersonforetak – ENK)

A sole proprietorship is the simplest form of business in Norway. It is owned and operated by one person, and there is no legal separation between the owner and the business. This means the owner is personally liable for all obligations and debts.

Sole proprietorships are often chosen by freelancers, consultants and small service providers. There is no minimum share capital, registration is relatively quick, and accounting and reporting requirements are simpler than for limited companies. However, because of the personal liability and less flexible tax planning, this form is usually best suited for smaller, low‑risk activities.

Private limited company (Aksjeselskap – AS)

An AS company is the most popular form for small and medium‑sized businesses in Norway. It is a separate legal entity, which means the shareholders are normally only liable up to the amount of their share capital. The minimum share capital is relatively low, and can be paid in cash or, under certain conditions, in assets.

Running an AS involves stricter formal requirements than a sole proprietorship: you must have a board, keep double‑entry accounts, file annual financial statements and follow specific rules for dividends and loans to shareholders. In return, you gain better protection of personal assets, easier access to investors and a more professional image towards customers and partners.

General partnership (Ansvarlig selskap – ANS/DA)

A general partnership is a company owned by two or more partners. In an ANS, all partners have unlimited and joint liability for the company’s obligations. In a DA, each partner is liable only for a defined share of the total obligations, but the liability is still personal.

Partnerships are often used when several people want to run a business together without establishing an AS, for example small local businesses or professional practices. There is no minimum capital requirement, but a written partnership agreement is strongly recommended. From an accounting perspective, partnerships must keep proper accounts and report to the authorities, and partners are taxed on their share of the profit.

Branch of a foreign company (Norskregistrert utenlandsk foretak – NUF)

A NUF is a branch of a company that is legally established in another country but operates in Norway. The foreign company remains the legal entity, while the Norwegian branch is registered in the Norwegian Register of Business Enterprises.

This form is often chosen by foreign businesses that want to test the Norwegian market or carry out specific projects without creating a separate Norwegian company. A NUF must follow Norwegian rules on accounting, invoicing, VAT and employer obligations for its Norwegian activity. The liability lies with the foreign company, and the tax treatment depends on where the business is considered tax resident and where the income is generated.

Public limited company (Allmennaksjeselskap – ASA)

A public limited company is designed for larger businesses that want to raise capital from the public or be listed on a stock exchange. The minimum share capital is significantly higher than for an AS, and the company must meet stricter requirements regarding corporate governance, board composition and reporting.

Because of the complexity and cost, the ASA form is mainly used by large corporations. For most small and medium‑sized enterprises, an AS will be more appropriate.

Other company forms

Norwegian law also provides for other, more specialised legal forms, such as cooperatives, foundations and associations. These are typically used for non‑profit activities, member‑owned businesses or specific sector regulations.

When choosing the type of company in Norway, it is important to consider risk, expected turnover, number of owners, need for investors and long‑term plans. The chosen form will determine which accounting rules apply, what must be reported to the authorities and how profits are taxed. Professional accounting support helps ensure that the company structure and financial management are aligned with Norwegian regulations from the start.

Business costs

Business costs in Norway are strictly regulated and must be directly connected to generating income in order to be tax deductible. Proper classification and documentation of expenses are essential for correct accounting and for avoiding problems during a tax audit. For foreign entrepreneurs, understanding which costs are accepted by the Norwegian Tax Administration (Skatteetaten) is particularly important.

General rules for deductible business expenses

As a rule, a cost is deductible if it is necessary for running the business and has a clear business purpose. Private expenses are never deductible, and mixed expenses must be split between private and business use. All costs should be documented with invoices or receipts that meet Norwegian requirements, and payments above certain thresholds should be made via bank transfer rather than cash.

Typical deductible business costs

Common deductible costs for companies in Norway include:

• Office rent, shared office space and warehouse costs
• Electricity, internet, phone and other utilities used for business
• Accounting, legal and consulting services
• Tools, machinery, equipment and software used in the business
• Marketing, website, domain and hosting costs
• Travel expenses related to customer visits, meetings and projects
• Insurance policies connected to business activity
• Bank fees and interest on business loans
• Training and courses that maintain or improve professional competence

Wages, employer contributions and other personnel costs are also fully deductible, provided they are correctly reported and paid through the Norwegian payroll system.

Depreciation of fixed assets

More expensive assets, such as vehicles, machines and larger IT equipment, are not deducted in full in the year of purchase. Instead, they are capitalised and depreciated over several years according to Norwegian tax rules. Different asset groups have different depreciation rates, and correct classification is important for both tax and financial reporting.

Representation, gifts and meals

Norwegian rules for representation and gifts are strict. Only certain types of representation costs are partly deductible, and there are clear limits for what is accepted. Everyday meals for the owner or employees are normally considered private and are not deductible, unless they are directly linked to business travel or specific work assignments outside the normal workplace.

Home office and mixed use costs

If you run your business from home, you may in some cases deduct a standard home office allowance or a proportion of actual costs, depending on the situation. The same applies to assets and services used both privately and for business, such as a mobile phone or car. In such cases, only the business-related part is deductible, and the allocation must be reasonable and documented.

VAT and business expenses

For companies registered for VAT (mva), input VAT on business purchases can usually be deducted, provided the purchase is related to VAT-liable activity and the invoice meets formal requirements. Some costs, such as certain financial services, health services or rental of residential property, are outside the VAT system and do not give the right to deduct input VAT.

Importance of correct documentation

To secure deduction of business costs, all expenses must be documented with proper vouchers: invoices, receipts, contracts or travel expense reports. The documentation must clearly show the supplier, buyer, date, amount, description of the goods or services and, when relevant, VAT. Good routines for storing and organising documentation make accounting more efficient and reduce the risk of adjustments and penalties during a control from Skatteetaten.

Professional accounting support helps ensure that all business costs are correctly classified, documented and reported in line with Norwegian regulations, which in turn optimises tax deductions and reduces risk for the company.

Audit obligation

In Norway, not every company is required to have its financial statements audited. The audit obligation depends mainly on the legal form of the company and on specific size thresholds related to revenue, balance sheet total and number of employees. Understanding when an audit is mandatory helps you plan costs, choose the right company form and avoid penalties for non-compliance.

When is an audit mandatory in Norway?

As a general rule, all larger companies and most limited liability companies (AS) are subject to statutory audit. A Norwegian company usually has an audit obligation if it exceeds at least two of the following thresholds for two consecutive financial years:

• Operating revenue above a set limit (updated regularly by Norwegian law)
• Balance sheet total above a set limit
• Average number of full-time employees above a set limit

Public limited companies (ASA), financial institutions and other regulated entities are always required to have an audit, regardless of size. Subsidiaries of foreign companies may also be obliged to have an auditor, especially if they are part of a larger group or if required by the parent company’s jurisdiction or internal policies.

Voluntary exemption from audit for small companies

Small private limited companies (AS) that stay below the statutory thresholds can choose to opt out of the audit obligation. This decision must be approved by the general meeting and registered with the Norwegian Register of Business Enterprises (Brønnøysundregistrene). Many start-ups and small businesses use this possibility to reduce administrative costs.

Even if an audit is not legally required, some companies still choose to have their accounts audited voluntarily. An independent auditor’s report can increase trust among investors, banks, suppliers and potential business partners, and may be requested when applying for financing or public tenders.

Role and responsibilities of the auditor

A statutory auditor in Norway must be an approved external professional, independent from the company’s management and owners. The auditor’s main task is to examine the annual accounts and the board of directors’ report, and to confirm whether they are prepared in accordance with the Norwegian Accounting Act and generally accepted accounting principles.

The auditor assesses whether the financial statements give a true and fair view of the company’s financial position, checks internal controls and evaluates the risk of material misstatements due to error or fraud. The conclusions are presented in an auditor’s report, which is filed together with the annual accounts and becomes publicly available.

Consequences of not complying with audit rules

If a company that is legally required to have an audit fails to appoint an auditor or does not submit audited financial statements, it may face penalties from the Norwegian authorities. These can include late filing fees, orders to correct the situation, and in serious or repeated cases, forced dissolution of the company.

Company owners and board members are responsible for ensuring that the audit obligation is correctly assessed each year and that an approved auditor is appointed when required. Working closely with a professional accounting firm helps to monitor thresholds, interpret legal changes and maintain full compliance with Norwegian audit regulations.

Sole proprietorship

A sole proprietorship in Norway (enkeltpersonforetak, often abbreviated as ENK) is the simplest and most common form of running a small business. It is easy to register, has low formal requirements and is often chosen by freelancers, consultants, craftsmen and small service providers. At the same time, it is important to understand how accounting, taxation and legal responsibility work in this form of business.

Key characteristics of a sole proprietorship

In a Norwegian sole proprietorship there is no legal separation between the owner and the business. The enterprise is owned and managed by one person, who is personally responsible for all obligations. This means that both business assets and the owner’s private assets can be used to cover business debts.

A sole proprietorship does not have share capital and does not issue shares. Decisions are made directly by the owner, which gives a lot of flexibility but also requires discipline in keeping documentation and fulfilling reporting duties.

Registration and basic obligations

To start a sole proprietorship in Norway, the owner must have a Norwegian national identity number or D-number. The business is registered in the Central Coordinating Register for Legal Entities, and in many cases also in the Register of Business Enterprises. Registration is done electronically via the Altinn portal.

From the accounting perspective, the owner must:

• keep orderly records of income and expenses
• store invoices and other documentation for the required period
• report income in the personal tax return
• register for VAT (MVA) when the turnover threshold is exceeded

Accounting and bookkeeping duties

The scope of accounting obligations for a sole proprietorship depends mainly on the level of turnover and whether the business has employees. Smaller ENKs often have simplified bookkeeping requirements, but they are still obliged to document all transactions and keep records in line with Norwegian accounting rules.

Even if full statutory accounts are not required, it is strongly recommended to maintain a clear separation between private and business finances, for example by using a dedicated business bank account. This makes it easier to prepare tax returns, control liquidity and demonstrate documentation in case of a tax audit.

Taxation of a sole proprietorship

In a sole proprietorship, business profit is taxed as the owner’s personal income. The company itself does not pay corporate income tax. Instead, the net result of the business (income minus deductible costs) is included in the owner’s personal tax return and taxed according to Norwegian progressive tax rates.

The owner is also responsible for paying advance tax and social security contributions. If the business is registered for VAT, the owner must submit VAT returns and pay collected VAT to the tax authorities within the applicable deadlines.

Advantages and limitations

The main advantages of a sole proprietorship in Norway are simple setup, low administrative burden and full control over the business. This form is often ideal in the early stages of activity or for individuals who provide services on their own.

The key limitation is unlimited personal liability. If the business incurs debts or tax arrears, the owner is personally responsible. For enterprises with higher risk, larger investments or several owners, it may be more appropriate to consider a limited liability company (AS).

When to consider changing to another company form

As the business grows, the owner of a sole proprietorship may reach a point where changing the legal form becomes beneficial. This is often the case when:

• turnover and profit increase significantly
• the business plans to hire more employees
• there is a need to limit personal liability
• external investors or partners are to be involved

Transitioning from a sole proprietorship to an AS company can provide better protection of private assets and more flexibility in tax planning, but it also brings stricter accounting and reporting obligations.

Subsidiary of a foreign company

A subsidiary of a foreign company in Norway is usually established as a Norwegian limited liability company (AS) that is fully or partly owned by a foreign parent. It is treated as a separate legal entity, which means it has its own organisation number, accounting obligations and tax responsibilities in Norway, regardless of where the parent company is located.

Legal and registration requirements

To register a subsidiary, you must submit the necessary documents to the Brønnøysund Register Centre. The company must have a Norwegian business address and a Norwegian organisation number. The parent company’s articles of association and registration documents from its home country are usually required, often with certified translations.

The subsidiary must have a board of directors. In many cases, at least one board member or deputy must be resident in Norway or in another EEA country. The company also needs articles of association and a share capital that meets Norwegian AS requirements.

Accounting and reporting obligations

A Norwegian subsidiary is subject to the Norwegian Accounting Act and Bookkeeping Act. It must keep accounting records in accordance with Norwegian standards, maintain proper documentation for all transactions and store accounting material for the required period. Annual financial statements must be prepared, and in many cases filed with the Register of Company Accounts.

Depending on size thresholds, the subsidiary may also be subject to statutory audit. Even if the parent company is audited abroad, the Norwegian entity is assessed separately under Norwegian rules.

Taxation and VAT

The subsidiary is considered a Norwegian tax resident and is taxed on its worldwide income, with relief provided under applicable tax treaties. It must submit a corporate tax return each year and pay advance tax based on estimated profits. Transfer pricing rules apply to transactions between the subsidiary and the foreign parent or other group companies, and documentation may be required to show that prices are set at arm’s length.

If the subsidiary carries out VAT-liable activities and exceeds the registration threshold, it must register for VAT in Norway. This involves periodic VAT reporting and correct treatment of cross-border services and goods, including import VAT and reverse charge mechanisms where relevant.

Employment and payroll

When the subsidiary hires employees in Norway, it becomes an employer under Norwegian law. This means obligations related to payroll accounting, reporting through the a-melding system, payment of employer’s social security contributions and withholding of income tax from salaries. Norwegian labour law, collective agreements (where applicable) and health and safety regulations must be followed, even if employment contracts are coordinated with the foreign parent.

Advantages of a Norwegian subsidiary

Operating through a subsidiary offers a clear separation of liability between the parent company and Norwegian operations. It can strengthen the company’s local presence, build trust with Norwegian customers and partners, and simplify compliance with local accounting, tax and employment regulations. In many cases, a subsidiary is more flexible for long-term growth than operating only through a branch or temporary registration.

Professional accounting support in Norway helps foreign groups set up the right structure, comply with local rules and optimise tax and reporting processes for the subsidiary from the start.

AS company

An AS company (Aksjeselskap) is the most common form of limited liability company in Norway and is usually the preferred structure for small and medium-sized businesses. It is a separate legal entity, which means the company is responsible for its own obligations and liabilities, not the owners personally.

Key characteristics of an AS company

An AS company is owned by one or more shareholders. Their ownership is represented by shares, and their financial risk is normally limited to the capital they have invested. The company must have a board of directors and follow formal rules for decision-making, reporting and documentation.

From an accounting perspective, an AS is required to keep orderly accounts, submit annual financial statements and follow Norwegian bookkeeping and accounting legislation. This makes it a transparent and predictable form for both authorities and business partners.

Share capital and ownership

The minimum share capital for a Norwegian AS is relatively low compared to many other countries, which makes this form accessible for entrepreneurs. The capital can be paid in cash or, under certain conditions, in kind. Once the company is registered, the share capital becomes part of the company’s equity and is reflected in the balance sheet.

Shares can be transferred to new owners, which makes it easier to bring in investors or sell the business. Any changes in ownership must be documented and reported, and the shareholder register must be kept up to date.

Management and formal obligations

An AS company must have at least a general meeting of shareholders and a board of directors. Larger companies may also need a managing director and, in some cases, a corporate assembly. The board is responsible for the overall management of the company, while the general meeting is the highest decision-making body.

There are clear formal requirements for minutes from board meetings and general meetings, approval of annual accounts and decisions on dividend distribution. Proper documentation is essential for correct accounting and for meeting audit or control requirements from the Norwegian authorities.

Accounting and reporting duties

All AS companies are obliged to keep accounts in accordance with the Norwegian Bookkeeping Act and Accounting Act. This includes ongoing bookkeeping, reconciliation of accounts, preparation of annual financial statements and submission of tax returns. Depending on size and turnover, some AS companies will also be subject to statutory audit.

Typical reporting obligations include annual accounts to the Register of Company Accounts, corporate income tax returns, VAT returns if the company is VAT-registered, and employer reporting if the company has employees. Using a professional accountant in Norway helps ensure that deadlines are met and that the accounts comply with current regulations.

Taxation of an AS company

An AS is taxed as a separate entity. The company pays corporate income tax on its profits according to the Norwegian corporate tax rate. If the company distributes dividends to shareholders, these are taxed at the shareholder level under Norwegian rules for dividend taxation.

This separation between company and owner taxation can provide planning opportunities and more predictable cash flow. It also makes the AS form attractive for foreign owners who want a clear distinction between personal and corporate finances.

When is an AS company the right choice?

An AS company is often the best solution when you plan to grow, hire employees, or cooperate with larger clients and public institutions. The limited liability, clear structure and established accounting and reporting framework make it a professional and trusted form of business in the Norwegian market.

For foreign entrepreneurs and companies entering Norway, establishing an AS can be an efficient way to operate locally, comply with Norwegian accounting rules and build credibility with customers, suppliers and authorities.

Company car

A company car in Norway can be a valuable benefit for employees and a practical tool for running your business, but it also comes with clear tax and accounting rules. Understanding how to classify, use and report a company car is essential to avoid unexpected tax costs and errors in your accounts.

Company car vs. private car used for business

Norwegian regulations distinguish between a company-owned car and a private car used for business purposes. This distinction affects both taxation and how costs are recorded in the accounts.

• Company car: The vehicle is owned or leased by the company and is available to the employee. Private use is normally taxed as a benefit in kind.
• Private car used for business: The car is owned by the employee or sole proprietor. The business reimburses mileage according to official rates instead of covering all car-related costs.

Choosing the right model depends on the extent of business use, the value of the car, and whether the employee needs the vehicle for private use.

Taxation of company car (benefit in kind)

When an employee or shareholder has a company car available for private use, this is treated as a taxable benefit in kind in Norway. The value of the benefit is calculated according to standard rules set by the tax authorities, usually based on the car’s list price as new and its age.

The calculated benefit is added to the employee’s salary for tax purposes and must be reported through the payroll system. The company is responsible for withholding tax and paying employer’s social security contributions on the benefit.

It is important to document whether the car is used privately or only for business. If the car is used exclusively for business, you must be able to prove this with a detailed driving log and internal guidelines that restrict private use.

Accounting treatment of company car costs

All costs related to a company car must be recorded in the company’s accounts. This typically includes:

• Purchase price or leasing costs
• Fuel or electricity
• Insurance and annual road tax
• Service, repairs and maintenance
• Tolls, parking and ferry tickets related to business trips

For purchased vehicles, the car is recorded as a fixed asset and depreciated over its expected useful life in accordance with Norwegian accounting and tax rules. For leased vehicles, lease payments are usually expensed on an ongoing basis. All documentation, such as invoices and contracts, must be stored in line with Norwegian bookkeeping regulations.

Company car in sole proprietorships

For sole proprietorships, the rules differ slightly from limited companies. In many cases, it is more beneficial for the owner to use a private car and charge the business a mileage allowance instead of having a company-owned car. The mileage allowance is then recorded as a business expense, while the car itself remains a private asset.

If the car is classified as a business asset in a sole proprietorship, strict documentation is required to separate business and private use. Private use may lead to adjustments in the tax base and should be carefully evaluated with an accountant.

Mileage allowance and travel logs

When a private car is used for business, the company can reimburse the driver based on official mileage rates. To support this, a detailed travel log is required, showing date, purpose of the trip, route and distance driven. This log is important both for tax purposes and as documentation in case of a tax audit.

Choosing the right solution for your business

Deciding between a company car and mileage allowance should be based on a thorough assessment of costs, tax consequences and the actual use of the vehicle. Factors such as the number of business trips, distance, type of car and the employee’s private needs all play a role.

An experienced accountant in Norway can help you calculate the total cost of each option, ensure that the company car is correctly recorded in the accounts and that all benefits and allowances are reported in line with Norwegian tax regulations.

Employer obligations

Hiring employees in Norway comes with a number of formal employer obligations. Fulfilling them correctly is crucial not only for compliance with Norwegian law, but also for avoiding penalties and ensuring predictable labour costs.

Registering as an employer

Before paying any salary, the company must be registered as an employer in the Central Coordinating Register for Legal Entities and, if applicable, in the VAT Register. New employees must be reported through the a-melding system, which is submitted electronically every month. This report contains information about salary, benefits, tax deductions and employer’s social security contributions.

Payroll, tax and social security

Norwegian employers are responsible for calculating and withholding income tax from employees’ salaries according to the tax deduction card (skattekort) issued by the tax authorities. The withheld tax is paid to the tax office, usually every second month. In addition, the employer pays employer’s National Insurance contributions (arbeidsgiveravgift), calculated as a percentage of gross salary, with the rate depending on the geographical zone where the company is registered.

All salary payments, bonuses, benefits in kind and reimbursements must be processed through an approved payroll system and reported via a-melding. Employers must keep payroll records and documentation for several years in case of control by the tax authorities or the Labour Inspection Authority.

Employment contracts and working conditions

Every employee in Norway must have a written employment contract. The contract should specify position, working hours, salary, overtime rules, notice periods and other key terms. Many sectors are covered by collective agreements or general application of minimum wage regulations, which set binding minimum pay and working conditions.

Employers must comply with the Working Environment Act, which regulates working hours, overtime, rest periods, holidays, sick leave and protection against unfair dismissal. There are also specific rules for temporary employment, part-time work and hiring from staffing agencies.

Mandatory pension and insurance

Most employers are required to establish an occupational pension scheme (OTP) for their employees. The minimum contribution is set by law and is calculated as a percentage of the employee’s salary. Contributions and any administrative fees must be accounted for correctly and paid on time.

Depending on the industry and type of work, employers may also be obliged to provide occupational injury insurance and other statutory insurances. These costs are part of the total employment cost and should be included in the company’s financial planning.

Reporting, documentation and deadlines

Norwegian employer obligations are closely linked to regular reporting. The a-melding must be submitted every month, even if no salary has been paid, as long as the company is registered as an active employer. Late or incorrect submissions can lead to daily penalties and additional controls.

Employers must keep documentation such as employment contracts, timesheets, payslips, tax reports, pension agreements and HSE documentation. Proper organisation of these documents simplifies accounting, annual reporting and potential audits.

Health, safety and employee follow-up

Employers are responsible for ensuring a safe and healthy working environment. This includes risk assessments, HSE routines, training, and follow-up of sick leave. In many cases, companies must have an internal control system and cooperate with a company health service (bedriftshelsetjeneste), especially in risk-exposed industries.

Correct handling of sick pay, parental leave, holiday pay and other statutory benefits is also part of the employer’s obligations and has a direct impact on payroll accounting.

Because Norwegian employer regulations are detailed and frequently updated, many companies choose to cooperate with an accounting office that offers payroll and HR support. Professional assistance helps ensure correct calculations, timely reporting and full compliance with Norwegian labour and tax legislation.

Safety at work

In Norway, safety at work is a core legal and practical obligation for every employer. Good health, safety and environment (HSE – “HMS” in Norwegian) routines are not only required by law, but also reduce absence, prevent accidents and protect the company from penalties and compensation claims.

Legal framework and employer responsibility

Workplace safety is mainly regulated by the Working Environment Act (Arbeidsmiljøloven) and related regulations. The employer is responsible for ensuring a fully safe working environment, both physically and psychosocially. This includes risk assessment, preventive measures, training, follow-up and documentation.

From an accounting and compliance perspective, safety at work affects how you budget, record costs and document that the company meets its legal obligations. Many HSE-related expenses are deductible business costs and should be properly classified in the accounts.

HSE routines and documentation

All companies in Norway must work systematically with HSE. In practice this means:

• Preparing written HSE procedures adapted to the company’s size and risk
• Carrying out and documenting regular risk assessments
• Registering and following up accidents, near-misses and occupational illnesses
• Ensuring that employees receive necessary safety training and information

These activities generate documentation that should be stored together with other company records. Proper documentation is important during inspections by the Norwegian Labour Inspection Authority and can also be requested by auditors or insurance companies.

HSE costs in the accounts

Typical safety-related expenses that should be recorded in the company’s accounts include:

• Protective equipment and workwear
• Safety training and courses (for example first aid, use of machinery, chemical handling)
• HSE consultancy services and risk assessments
• Health checks required by law for certain types of work
• Adaptations of premises and equipment to meet safety standards

Correct classification of these costs helps demonstrate that the company actively invests in a safe working environment and ensures that all eligible expenses are tax deductible.

Internal control and cooperation with employees

Norwegian rules emphasise cooperation between employer and employees. Depending on the size of the company, you may be required to have a safety representative and a working environment committee. Minutes from meetings, internal control reports and action plans should be kept as part of the company’s documentation.

For many businesses, it is efficient to integrate HSE follow-up with other internal control and quality systems. This makes it easier to coordinate safety work with financial planning, budgeting and reporting.

Why safety at work matters for your business

Systematic HSE work reduces the risk of accidents, sick leave and disputes. It also strengthens the company’s reputation and can be a requirement in tenders and contracts, especially in construction, oil and gas, and other high-risk industries.

A professional accounting partner in Norway can help you:

• Set up correct accounts for HSE-related costs
• Ensure that safety expenses are properly documented for tax and audit purposes
• Coordinate HSE documentation with other statutory company records

Combining solid accounting routines with structured safety at work gives your company a stable foundation for long-term, compliant operations in the Norwegian market.

ALTINN portal

ALTINN is the main digital portal used by companies in Norway to communicate with public authorities. Through this platform you submit most mandatory reports related to accounting, tax and employees. Understanding how ALTINN works is essential for correct and timely company accounting in Norway.

What is ALTINN used for?

ALTINN connects your company with several Norwegian institutions, including the Tax Administration (Skatteetaten), the Brønnøysund Register Centre and NAV. In practice, this means that most of your official accounting and reporting obligations are handled through one online account. Typical submissions include:

• VAT returns (mva-melding)
• Employer’s contribution and payroll reports (a-melding)
• Annual accounts and notes for limited companies
• Shareholder register statements
• Income tax returns for companies and sole proprietors
• Applications for refunds, grants or benefits related to employees

Access and roles in ALTINN

To use ALTINN, the company’s owner or director logs in with a Norwegian electronic ID and is then connected to the company’s organisation number. From there, different roles and rights can be assigned to employees or an external accountant. This role-based access is important for secure and efficient accounting processes, as it allows your accountant to submit forms and receive messages on behalf of the company.

ALTINN and daily accounting work

Modern accounting systems in Norway are often integrated with ALTINN. This allows VAT returns, payroll reports and other mandatory forms to be generated directly from your accounting data and sent electronically with a few clicks. For the company, this reduces the risk of errors, saves time and helps ensure that all deadlines are met.

All messages, decisions and confirmations from the authorities are also delivered to your company’s inbox in ALTINN. It is important to monitor this inbox regularly, as it may contain information about tax assessments, missing documentation or changes in reporting rules that affect your accounting.

Why the ALTINN portal matters for compliance

Using ALTINN correctly is a key part of staying compliant with Norwegian accounting and tax regulations. Late or incorrect submissions can lead to penalties, interest and unnecessary audits. A well-organised ALTINN setup, with clear roles and integration with your accounting system, helps keep your company’s financial reporting transparent, traceable and in line with current Norwegian law.

Import and export

Import and export activities in Norway are strictly regulated and closely monitored by the Norwegian Tax Administration, Customs (Tolletaten) and other authorities. From an accounting perspective, it is crucial to correctly document cross-border transactions, apply the right VAT treatment and keep clear records that can be easily verified during a control.

Import to Norway – accounting and VAT

When your company imports goods to Norway, customs and import VAT are normally calculated at the border or reported through the VAT return. Import VAT is usually deductible for VAT-registered businesses, provided the goods are used in taxable business activities and all documentation is in order.

Key accounting aspects of imports include:

• Correct classification of goods and customs codes (HS codes), which affect customs duties and reporting.
• Proper recording of customs value, freight, insurance and other costs that form the basis for import VAT.
• Booking import VAT as both input VAT and VAT liability in the accounts, according to the VAT return.
• Storing customs declarations, invoices from foreign suppliers and transport documents as part of the company’s accounting documentation.

Errors in import documentation or VAT reporting can lead to additional tax assessments, penalties and interest, so it is important to have clear routines and, if necessary, support from an accountant familiar with Norwegian regulations.

Export from Norway – VAT and documentation

Exports of goods from Norway are normally zero-rated for VAT, but this does not mean they are outside the VAT system. The transaction must still be documented and reported correctly in the accounts and in the VAT return.

For exports, companies should pay particular attention to:

• Issuing invoices that clearly show that the sale concerns export outside Norway and is zero-rated for VAT.
• Keeping transport documentation and export declarations that prove the goods have left Norway.
• Correctly classifying export revenue in the chart of accounts and VAT codes.
• Monitoring Incoterms and contract conditions, which may affect the timing of revenue recognition and risk transfer.

Service exports can be more complex, as the place of supply rules determine whether Norwegian VAT applies. For many B2B services delivered to foreign customers, the sale is outside the scope of Norwegian VAT, but the conditions must be assessed for each type of service.

Customs, duties and cross-border compliance

Norway is not a member of the EU, which means that trade with EU countries is treated as import and export, not intra-community trade. This has consequences for customs clearance, documentation and accounting treatment.

Companies engaged in international trade should establish routines for:

• Checking whether customs duties, excise duties or special taxes apply to imported goods.
• Ensuring that customs declarations match the information in the accounting system.
• Reconciling import and export data from the customs authorities with internal records.
• Monitoring changes in customs rates, free trade agreements and sanctions that may affect costs and legal obligations.

Accurate and consistent data between customs, invoices and accounting records reduces the risk of discrepancies during audits and helps maintain compliance with Norwegian and international regulations.

How an accountant can support your import and export business

Professional accounting support is particularly valuable for companies that import or export regularly. An experienced accountant can help you:

• Set up the chart of accounts and VAT codes to correctly reflect cross-border transactions.
• Implement routines for collecting and storing all required documentation.
• Prepare and submit accurate VAT returns that include import VAT and zero-rated exports.
• Analyse the profitability of international trade by separating costs and revenues by market or product group.

With proper accounting and tax handling of import and export, your company can reduce risk, avoid unnecessary costs and focus on growing in international markets while staying fully compliant with Norwegian regulations.
