What are the employer obligations for a Norwegian AS company?

Running an AS with employees in Norway creates significant ongoing obligations. Understanding them in full before making your first hire prevents costly mistakes.

Arbeidsgiveravgift (employer social security contribution)

The headline employer obligation is arbeidsgiveravgift — Norway's employer payroll tax. The national standard rate is 14.1%, applied to all remuneration paid to employees: gross wages, overtime, holiday pay, benefits in kind, and employer pension contributions.

The rate varies by zone. Businesses in northern and remote municipalities benefit from reduced rates designed to support employment in less-populated areas: - Zone 1 (most of Norway): 14.1% - Zone 2: 10.6% - Zone 3: 6.4% - Zone 4: 5.1% - Zone 5: 0% (selected Finnmark/North Troms municipalities)

Arbeidsgiveravgift is paid bimonthly — January-February liability is due by 15 March, and so on for 6 payment dates per year.

A-melding (monthly payroll reporting)

All employers must file A-melding (payroll report) by the 5th of each month for the previous month's payroll. The A-melding reports for each employee: gross wages, income category, tax deductions made (skattetrekk), municipality code, benefits in kind, pension contributions, and sick pay.

The A-melding is filed via Altinn. Most payroll software (Visma Lønn, Tripletex, Zmart) submits it automatically.

OTP — Obligatorisk tjenestepensjon

All employers in Norway must provide a workplace pension (OTP — obligatorisk tjenestepensjon). Minimum contribution: 2% of qualifying wages (wages between 1G and 12G — approximately NOK 124,028 to NOK 1,488,336 for 2025). There is no upper deductible limit on employer contributions up to 7% for defined contribution (innskuddspensjon).

OTP must be established within one month of the first employee starting. Most AS use a defined contribution innskuddsbasert pension scheme via a bank or insurance company (Storebrand, KLP, DNB Livsforsikring, Nordea Liv, etc.).

OTP contributions are paid monthly and are fully deductible as a business expense.

Feriepenger (holiday pay)

Employers must pay feriepenger (holiday pay) of minimum 10.2% of wages earned in the previous year. This is paid in June when employees take annual leave (typically 4 weeks). Employees aged 60 and over receive 12.5% on the first NOK 6G of wages.

Feriepenger is accrued as an expense when wages are paid and is a liability on the balance sheet until paid out in June.

Employer sick pay (sykepengedager 1–16)

For sick leave, the employer pays the employee's full wages for the first 16 calendar days (arbeidsgiverperioden). From day 17, NAV (the national insurance agency) takes over and pays sykepenger directly to the employee (100% up to 6G). The employer does not bear the cost of long-term illness.

For very small businesses with high risk of illness costs, NAV offers a refund scheme (Refusjon for sykepenger) for companies with fewer than 10 employees experiencing disproportionate sick leave.

Skattetrekkskonto (segregated tax account)

Employers are legally required to hold withheld employee tax (skattetrekk) in a separate bank account (skattetrekkskonto) that is segregated from the company's general operating account. This protects employee tax withholdings from being mixed with company funds. Failure to maintain this account is a criminal offence.

Employee rights compliance

Beyond the financial obligations, Norwegian employers must comply with arbeidsmiljøloven (Working Environment Act), which sets strict rules on: working hours (maximum 40 hours per week ordinary time, 10 hours per day), overtime limits and payment, notice periods, unfair dismissal protection, and health and safety requirements.

Employment contract requirement

All employees must have a written employment contract (arbeidsavtale) from day one. Standard templates are available via Arbeidstilsynet (the Labour Inspection Authority). The contract must specify wages, hours, notice period, and holiday entitlement.
