If you are a member of the National Insurance Scheme, you will have to pay national insurance contributions.

National insurance contributions are calculated on personal income and pension. The contribution rates for 2011are:
The basis for calculation of the contributions is set by the Tax Administration Authorities. The annual tax assessment notice will show how much you have paid in national insurance contributions.
If you do not pay taxes in Norway but are nevertheless a member of the National Insurance Scheme, it will be NAV that sets and collects the contributions.
The contribution rates for voluntary membership vary on the basis of whether the employer is required to pay employer’s contributions in Norway or not.
