Foreign companies in Norway: compliant from day one

Norway is a high-margin market with strict rules. The companies that win here treat compliance as a competitive weapon: registered correctly, paying people correctly, invoicing correctly — from the first contract.

What Norwegian rules require from you

• Entity registration: NUF (Norwegian branch) or AS (limited company) — the choice affects tax, liability, banking and how clients perceive you. See the full company formation guide.
• VAT: registration is mandatory once turnover passes NOK 50,000 in 12 months; construction services often involve reverse charge rules.
• Payroll: a-melding every month, employer contributions (14.1% standard), holiday pay, mandatory pension (OTP) and sick pay obligations.
• Workers: HMS cards for construction sites, ID checks, posted-worker rules and generalized minimum wages in several sectors.
• Reporting: assignments must be reported to the tax authorities (the old RF-1199 regime); missing it triggers liability and penalties.
• Permanent establishment: projects lasting beyond treaty thresholds create Norwegian tax liability — better planned than discovered.

PAYE: simplified payroll for foreign employers

Foreign employers without a Norwegian entity can use the PAYE scheme (skatteordning for utenlandske arbeidstakere). The employer deducts a flat 25% withholding (or 17.4% with a valid A1 certificate) and reports via a-melding monthly. The worker receives no tax return — the deduction is final. PAYE simplifies the tax calculation but does NOT remove employer obligations: you still register as an employer, file a-melding, and comply with sector-specific rules.

D-numbers and tax cards

Every foreign worker needs a D-number (temporary Norwegian ID) and a tax card before starting work. Apply through Skatteetaten or visit a SUA office (Servicekontor for utenlandske arbeidstakere) for same-day processing of D-number, tax card and A1 verification in one visit. Without a tax card, the employer must withhold 50%. Start this process before the worker arrives — not after.

A1 certificates and social security

An A1 certificate proves which country collects social security for a posted worker. With a valid A1 from the home country, the employer avoids Norwegian arbeidsgiveravgift (14.1%) and the worker avoids trygdeavgift (7.6%) — social security stays in the home country. The A1 must be applied for before deployment; the maximum posting period is 24 months. For PAYE workers, an A1 reduces the withholding rate from 25% to 17.4%.
