📌 What Are Employer’s National Insurance Contributions?
Employer’s national insurance contributions (arbeidsgiveravgift) are mandatory payments made by employers to finance Norway’s National Insurance Scheme. They are calculated as a percentage of an employee’s gross salary and taxable benefits.
💼 The 2025 Standard Rate
As of 1 January 2025, the government has confirmed the following:
- Standard Rate: 14.1% of total gross salary and taxable benefits.
- Abolished Surcharge: The extra 5% contribution on income above NOK 850,000 (previously applied in 2024) is abolished in 2025.
- Regional Relief: Lower rates may apply in sparsely populated areas to encourage job creation.
⚖️ Contribution Rates by Region
Norway uses a zone-based system where contributions vary depending on where the employer is established. In 2025:
| Zone | Rate | Notes |
|---|---|---|
| Zone 1 (Urban areas) | 14.1% | Applies to most companies nationwide. |
| Zone 2 | 10.6% | Encourages business activity in less populated regions. |
| Zone 3–5 (Remote areas) | As low as 0% | Special tax relief to promote rural employment. |

📊 Example Calculation for 2025
Suppose an employee earns NOK 600,000 in gross salary:
- Zone 1 (14.1%): Employer pays NOK 84,600 in contributions.
- Zone 2 (10.6%): Employer pays NOK 63,600.
- Zone 5 (0%): Employer pays nothing in contributions.
This highlights why many employers consider location-based advantages when hiring.
🌍 Social Security Agreements & Exemptions
Employers may be exempt from Norwegian contributions if employees are covered by another country’s social security system under a bilateral social security agreement (e.g., with the EU, USA, Canada, or India). Companies must apply and provide proper documentation for exemptions.
✅ Deductibility for Employers
Employer’s contributions are deductible for corporate tax purposes. This reduces the overall tax burden but still represents a significant payroll cost that companies must budget carefully.
📅 Key Compliance Rules
- Contributions must be reported and paid together with monthly payroll tax filings.
- Employers must obtain tax deduction cards for all employees.
- Non-compliance may result in penalties and interest charges.
