Employer’s national insurance contributions

  • Updated: 21 January 2022

How to calculate employer's national insurance contributions and what information that you must provide concerning the contributions in the a-melding.

    This is new from 2023

    From 2023, employer's additional national insurance contributions must be paid when the total taxable salary from a main legal entity to a single income recipient exceeds NOK 750,000. See Employer’s additional national insurance contributions on salary income over NOK 750,000 for information on how to calculate and what information you must provide in the a-melding about employer’s additional national insurance contributions 

    Enterprises that are in financial difficulties in accordance with the ESA's guidelines concerning state aid to enterprises in difficulty, should use the high rate in all zones. From 2023 a separate calculation code has been created to be used by enterprises that are in financial difficulties. 

    Brief information about employer’s national insurance contributions in the a-melding

    As an employer, you have a responsibility to calculate and pay employer's national insurance contributions. Employer's national insurance contributions are based on the employees' gross salaries.

    The rate you use to calculate employer’s national insurance contributions depends on the following:

    • zone – in which municipality the enterprise has its head office. Due to the local and regional government reform, from 2020 there is no longer a one to one relationship between the employer’s national insurance contribution zone and the municipality. See employer’s national insurance contribution - zone subdivision for an overview of zones and rates. Zones for employer's national insurance contributions are also available on Norgeskart.no.
    • calculation code – the type of business activity you carry out.

     

    Enterprises that are experiencing financial difficulties in accordance with the ESA's guidelines concerning state aid to enterprises in difficulty should generally use the high rate in all zones. If you are using the reduced rate, you are confirming that you are not in financial difficulty.


    There are seven different calculation codes:

    • general industries
    • health enterprises and parts of the public administration
    • agriculture and forestry, fisheries etc.
    • reporting of payroll withholding tax only
    • PAYE for Svalbard (payroll deduction)
    • sector-exempt activity
    • road freight transport


    In the a-melding, you must provide information on how you calculate employer's national insurance contributions and the amount that you must pay.

    You must also indicate whether each individual salary payment and benefit is to be included in the basis for employer's national insurance contributions. See a more detailed description of this under each individual salary payment and benefit.

    For more information, see general information on national insurance contribution.

    See the Directorate of Taxes’ report on employer’s national insurance contributions to the Norwegian National Insurance Scheme for 2023 (in norwegian only).

    Zone

    In order to find the right zone, see overview of zones and the supplementary information concerning zones with a description of the exceptions.

     

    Contribution basis

    There are three types of contribution basis:

    1. Employer's national insurance contributions on salary and  other payments.

    Concerns salary and other benefits subject to contributions.

    Specify the gross aggregated salary and other benefits subject to contributions.

    You must also include salary and benefits subject to contributions which:

    • cannot be linked to an income recipient
    • are not included in any of the other contribution bases, e.g. benefits below the reporting obligation threshold

    You should not include salary and benefits for:

    • employees posted from the USA or Canada
    • employees on-board ships in international service

     

    2. Employer's national insurance contributions on pension contributions and premiums

    Concerns employers’ contributions and premiums for annuity and pension schemes which are subject to contributions.

    Specify the gross aggregated contributions and premiums subject to contributions. Must be specified in the calendar month in which you paid the premium.

    Distribute the basis between the relevant contribution zones on the same basis as other benefits subject to contributions in the same calendar month.

    If you deduct premiums for pension schemes from the employee’s salary and the non-deductible amount is paid to the pension scheme, you should reduce the total taxable share of pension contributions and premiums with the employee’s non-deductible amount. You must not reduce the basis for employer's national insurance contributions by reporting the deductions you make in the employee’s salary every calendar month here. The employee’s non-deductible amount should only reduce the basis for employer's national insurance contributions for pension contributions and premiums for the calendar month where you have paid the full contribution to the pension scheme.

     

    3. Refunds of sickness benefits etc. giving a reduction in the contribution basis

    Concerns salary and other benefits which you have previously paid for employees who, for example, were on sick leave or maternity leave.


    Specify the gross aggregated refund which gives a reduction in the contribution basis. Must be specified in the calendar month in which you receive a refund from NAV.

    The amount is negative and must reduce the total calculated employer's national insurance contributions. You must specify the amount with a minus sign.

    Use the same contribution rate that you use to calculate employer's national insurance contributions.

     

     

    Tax-free amount and de minimis aid

    The contribution-free amount means that you are can apply a lower rate (differentiated rates) than 14.1 percent when calculating the contributions. You can only apply the lower rate (the differentiated rate) to the contribution-free amount.

    The contribution-free amount is NOK 500,000 per year for: 

    • general industries in zone 1a
    • sector-exempt activity zones 1a - 5
       

    The contribution-free amount is NOK 250,000 per year for:

    • road freight transport in zone 1a

    Once the contribution-free amount has been used up, you must apply the 14.1 percent rate for the rest of the year. Only one contribution-free amount applies per legal entity (declarant).

    See also more about reporting contribution-free amounts for groups of enterprises

     

    De minimis aid

    If you have received other de minimis aid in the calendar month for which you are submitting an a-melding, you must specify this in the a-melding.

    See also the explanatory information concerning de minimis aid

    Only applies if:

    • the enterprise can calculate differentiated rates within a contribution-free amount (de minimis aid). This means enterprises that are covered by: 
      • calculation code “General industries” in zone 1a
      • calculation code “Road freight transport” in zone 1a
      • calculation code “Sector-exempt activity" in all zones except zone 1

    If you haven't spent  the contribution-free amount when you receive de minimis aid, you must reduce the contribution-free amount by an amount which corresponds to the aid amount that you received.

    If the contribution-free amount is still a positive amount, you can apply the low rate when calculating the benefit.

     

    Example

    You run an enterprise in zone 1a, the calculation code is general industries, and the contribution-free amount is NOK 500,000 for a year. In January, your enterprise receives NOK 150,000 in de minimis aid.

    Contribution-free amount 500,000 – 150,000 = 350,000

    The contribution-free amount has not been used up and you can apply the low rate (differentiated rate) of 10.6 percent when calculating the employer's national insurance contributions. Applies until the remaining component of the contribution-free amount of NOK 350,000 has been spent.

    If you receive NOK 500,000 in de minimis aid, the contribution-free amount will be spent and you will have to calculate contributions using the rate of 14.1 percent.

     

    Itinerant enterprise - several zones

    Itinerant enterprise means that you have employees who:

    • work mainly in another zone with a higher rate than the enterprise is registered under
    • and that you are not obliged to register a sub-entity in the other zone.

    This applies for example to:

    • transport sector
    • construction and engineering sector
    • consultancy
    • manpower hire

     

    Fixed and non-fixed business activity

    If an itinerant enterprise conducts work in a different zone with a higher rate than the one where it is registered, the employer must use the higher rate for salary for both work that are attached to one place, and work that are not attached to one place (the so-called circumvention rule).

    If an itinerant enterprise conducts work in a different zone with a lower rate than the one where it is registered, the employer can only use the lower rate for work that is attached to one place (the so-called exemption rule). The contribution rate for work that is not fixed to one location//remote work (for example working from home) in zones with a lower rate than where the employer is registered, follows the general rule. The employer must therefore use the rate in the registered zone for the remote work.

     

    The majority of the work

    The majority of the work means that the employee has carried out more than half of the number of working days during the calendar month in another zone with a higher rate than the enterprise is registered under.

    If the employee carries out the majority of his or her work during a particular month in another zone with a higher rate than  the enterprise is registered under, you must apply this rate to a proportional share of the salary payments for that calendar month.

     

    Two sets of information

    If you report employer's national insurance contributions for an itinerant enterprise, you must provide two sets of information, one for each calculation zone.

    In the a-melding, you must provide information concerning:

    Work performed in another zone 
    Calculation code Calculation code
    Zone Specify the zone in which the itinerant enterprise operates 
    Contribution basis  Contribution basis linked to the zone above 
    Contribution rate  Applicable zone rate 

     

    Work performed in the zone under which the enterprise is registered
    Calculation code Calculation code
    Zone State the enterprise's zone
    Contribution basis Contribution basis linked to the zone above
    Contribution rate Applicable zone rate

     

    Mixed enterprise - several types of industry

    If you run several different types of business, including sector-exempt industry combined with another industry, you can apply the rates that apply to each of the industries.

    The condition for you to do this is that you:

    • have a clear accounting divide between the two industries.


    If you do not have a clear accounting divide: 

    • you must apply the highest rates to the entire contribution basis.

     

    Two sets of information

    If you report employer's national insurance contributions for mixed enterprise, you must provide two sets of information, one for each calculation zone.

    In the a-melding, you must provide information concerning:

    Sector-exempt activity
    Calculation code For example: sector-exempt activity
    Zone zone x
    Contribution basis Contribution basis linked to the calculation code above
    Contribution rate Rate linked to the calculation code above

    Calculation code For example agriculture and forestry, fisheries etc.
    Zone zone x
    Contribution basis Contribution basis linked to the calculation code above
    Contribution rate Rate linked to the calculation code above

     

    Total calculated employer's national insurance contributions

    In addition to information on how you calculate the employer's national insurance contributions, you must also state the total calculated employer's national insurance contributions as separate information in the a-melding. This is also the amount you must pay in employer's national insurance contributions.

    Calculate the total amount of employer's national insurance contributions you must pay and state a total amount.

     

    When you must submit reports

    You must provide information on employer’s national insurance contributions in the a-melding each month in which you specify salary or other benefits on which you calculate employer’s national insurance contributions.

    You must specify employer's national insurance contributions on pension contributions and premiums in the calendar month in which you paid the all of the contributions/premium.

    If you have specified the wrong contribution basis, you must correct this basis in the a-melding for the month which is wrong.

    You do not need to correct the information regarding income recipient.

     

    Example

    Magnus works in a store that is located in zone 1. He has NOK 40,000 in fixed salary.

    After the store has sent the a-melding for August, they discover that they by mistake have reported the numbers for August in zone 2.

    Example

    Ella works for a service company which is located in zone 2. She receives a fixed salary of NOK 40,000.

    • vehicle logbooks
    • scholarships

    In such cases, you can choose which month you make the change in.


    If the change concerns the current year, you can

    • change the employer’s national insurance contributions in the a-melding for the month in which the new information becomes known, or
    • change the employer's national insurance contributions in the a-melding for the month or months that the change concerns.


    If the change concerns a previous year, you can

    • change the employer’s national insurance contributions in the a-melding for the month in which the new information becomes known,

    Anna works for an electrical contractor. The firm has paid employer’s national insurance contributions on Anna’s fixed salary of NOK 50,000 per month.

    After three months, the employer is notified by the Norwegian tax administration that Anna has been a member of the Swedish national insurance scheme for the past three months.

    The firm should not pay employer’s national insurance contributions on the salary that is paid when Anna is not a member of the Norwegian National Insurance scheme.

    The firm opts to change the employer’s national insurance contributions in the month in which they became aware of Anna’s membership. They claim back the excess employer's national insurance contributions that they paid during the first three months.

    The firm does not need to change the information that has been specified for Anna during the first three months.

    Jacob works for a sales company. In January, he submits an estimate showing that he expects to drive approximately 18,000 kilometres in his own car on business during the year. The company considers the estimate to be accurate and pays Jacob a car allowance which is not subject to payroll withholding tax or contributions amounting to NOK 5,250 per month (NOK 63,000 for the whole year).

    At the end of the year, Jacob submits a vehicle logbook showing that he has driven a total of 14,500 kilometres. This corresponds to NOK 50,750 for the year in car allowance not subject to payroll withholding tax or contributions.

    Peter has received 63,000 - 50,750 = NOK 12,250 too much in car allowance not subject to payroll withholding tax or contributions.

    The sales firm opts to change the employer’s national insurance contributions in the month in which they received the vehicle logbook, i.e. December.

    If you need to alter the employer's national insurance contributions because an income recipient receives a benefit in the form of a back payment, specify the employer's national insurance contributions in the month in which the back payment takes place.

    If you need to alter the employer's national insurance contributions because an income recipient has repaid a benefit, you can choose which month you make the change in.

    If the repayment concerns the current year, you can:

    • change the employer’s national insurance contributions in the a-melding for the month in which the benefit is repaid, or
    • change the employer's national insurance contributions in the a-melding for the month or months that the repayment concerns

    If the change concerns a previous year, you can:

    • change the employer’s national insurance contributions in the a-melding for the month in which the benefit is repaid,
    • change the employer's national insurance contributions in the a-melding for the month or months that the repayment concerns, or
    • change the employer’s national insurance contributions in the a-melding for December.  

    Note! 
    You must correct the amount that the income recipient has paid back in the a-melding for the month or months in which the error was made. Only if there is a change in employer’s national insurance contributions can you choose which month to make the change in.
