Members of the National Insurance Scheme must pay National Insurance contributions. National Insurance contributions are stipulated as a percentage of personal income pursuant to the Taxation Act sections 12-2 and 12-10, cf. the National Insurance Act section 23-3. The rate for National Insurance contributions are decided by the Storting (the Norwegian parliament) every year. For 2008 it is:
- 7.8% of pay and other personal income
- 11% of income from self-employment/business activities and other personal income
For employees, National Insurance contributions are normally included in the employer’s deduction of withholding tax and they are included in the deduction tables. National Insurance contributions for self-employed persons with an obligation to pay such contributions are included in the advance tax. If an employee is not taxed in Norway, the National Insurance contributions must be paid to the local Norwegian Labour and Welfare Service (NAV) office.
