Overtime payment date

Full-time and administrative employees should register overtime in the Self-service portal. Go to Payment schedule for salaries and refunds - to see deadlines for employees and managers, and dates for when you get the pay.

Overtime regulations

Overtime must be agreed in advance with your manager and must be registered in the Self-Service Portal.

The Norwegian Working Environment Act sets limits on how many overtime hours you can work. All overtime must be ordered and approved by your manager and be registered in the Self-service portal.

Overtime work must be required and verifiable, and it can only be imposed to meet extraordinary needs during a limited period. Employees may not work beyond the agreed working hours as a permanent arrangement.

An employee is entitled to exemption from performing work in addition to agreed working hours when he or she requests this for health reasons or for well-founded social reasons. The employer is also obliged to exempt an employee who requests this when the work can be postponed or performed by others without harm.

Who is not entitled to overtime?

As a rule, employees in senior and particularly independent posts (Statens personalhåndbok, in Norwegian) are not entitled to overtime. If you have agreed with your manager that you will still have paid overtime, you must remember to register the overtime in the Self Service Portal.

Register overtime

If you have agreed with your manager that you will work overtime, register the overtime in the self-service portal or the DFØ app:

knapp Open the Self-service portal

Download the DFØ app

  • If you're a full time employee who normally register working hours in the Self-service portal, you add overtime hours in your time registration by choosing either "paid overtime" or "overtime w_/time off ". If you're a full time employee who normally don't register working hours, you go choose "paid overtime".
  • Part-time employee? Go to this section.'

Overtime work imposed is compensated by hourly wage + a percentage supplement as follows:

1. 50% supplement until 8 pm, and between 06 am and regular working hours
2. 100% supplement

  • between 8 pm and 6 am on weekdays
  • from Friday at 8 pm to Monday at 6 am
  • holidays/and public holidays

Compensatory time off instead of overtime pay

If you have worked obligatory overtime, you can take compensatory time off for the equivalent number of hours. You can choose whether to take compensatory time off for the overtime you have accumulated, or whether you want the amount to be added to your salary payment. The overtime supplement will be paid regardless.

Overtime limits

  • Overtime work must not exceed 10 hours during 7 days, 25 hours during 4 consecutive weeks, and 200 hours a year.
  • Total working hours must not exceed 13 hours per 24 hours and 48 hours per 7 days.
  • The limit of 48 hours per 7 days may be calculated according to an average over a period of 8 weeks, if total working time according to
    the Working Environment Act, section 5-10 second paragraph and section 10-6 fifth paragraph does not exceed 69 hours in any one week.

The limits may be extended by agreement with the civil servants’ unions, or after approval from the Norwegian Labour Inspection Authority, within the limits set out in Section 10-6 of the Working Environment Act.

According to the Working Environment Act, overtime is work in addition to normal working hours of 40 hours per week, while the Basic Collective Agreement (hovedtariffavtalen) in the State specifies normal working hours of 37.5 hours per week. Employees with a working week of 37.5 hours can therefore be required to work overtime in addition to the difference between a working week of 37.5 and 40 hours.

However, this does not mean a general extension in the framework of working hours per year. Statens personalhåndbok (the personnel handbook for State employees) states that: “If there are weeks in which the employee does not work more than normal working hours (37.5 hours), then the employee will not 'save up' or 'have a credit of' 2.5 hours per week for these weeks.

The number of hours on an annual basis that these 2.5 hours represent will therefore depend on the number of weeks during which overtime is worked”. The difference between 40 and 37.5 hours can therefore only be applied on a weekly basis, and it must also be settled according to summer / winter time practice.

Rest break before overtime work

If you are required to work overtime lasting more than 2 hours immediately after completing your regular working hours, you must first be granted a half-hour break, which will be included in the working hours.

Register overtime in other places/projects than you normally work

If your hours will be charged at other cost centres or projects, you must register as follows:

1) You must have information about the cost centre, any project number and which manager approves the hours in the self-service portal. You can get this information from a manager, HR employee, office manager, project economist or controller.

2) The employee enters the hours as 'Overtime for pay' in the DFØ app or the Self-Service Portal in the usual way. Note that you should NOT fill in posting information such as K-element 7, k-location or similar. Then you will get error message. Only the comments field should be filled in, see section 3.

You register as overtime for payment 011 on all (or overtime against departure 013 for technical / administrative employees who wish to do so).

3) In the comments field, type

To [name of manager to approve the appointments], [cost centre], [possibly subproject number].

Note that there is limited space here so if you follow this format you will have room for everything.

Example: To First name Last name 88888888, UV9999999999

4) The overtime hours will now be sent over to your manager (the transfer takes place on the night of the 1st, 15th and 23rd each month). Your manager will then be informed that you work elsewhere. Your manager should then forward the overtime hours to the manager in the other cost center/project. That person will register the information you entered in the comments field of the posting fields. Finally, the overtime hours will be posted for payment on the next salary after ordinary deadlines for payroll.

Additional hours and overtime for part-time employees

  • Additional hours are extra working hours in excess of your part-time position, up to the normal working hours for a one hundred percent position.
  • Overtime is hours in excess of normal working hours for one hundred percent position.
  • The normal working hours for a one hundred percent position are 7.00 hours per day summer time, 7.45 hours per day winter time and 7.30 hours per day, if you have the same working hours all year round.

Both additional hours and overtime must be agreed with your manager in advance.

Part-time employees registering working hours

If you have agreed with your manager that you will have paid for the extra hours you work, you must register that time as "paid overtime" in the time registration in the Self-service Portal. This applies to both extra time and overtime.

The overtime supplement is applied automatically only when the normal working day has been achieved. Until the normal working day is reached, ordinary hourly wages are paid (without supplements).

Part-time employees who do not register working hours

This applies, for example, to academic employees in part-time positions. If you have agreed with your manager that you will be working additional hours or overtime, you must register this in the Self Service Portal:

  • You register overtime via the tile "Register working hours" as "Paid overtime". Overtime supplements are then added automatically from the first hour.
  • You register additional hours via the tile "Remuneration". Guide: Register a remuneration (

Overtime food

Employees who are entitled to paid overtime generally cannot expect to have their meal expenses covered. However, in special situations where the employer deems it appropriate to provide paid overtime meals, the employee can be reimbursed up to 209 kroner (as of 2023). The work must extend at least three hours beyond regular working hours.

Typically, the employer's coverage of meal expenses is subject to taxation. However, the Norwegian Tax Administration has made an exception for employees who work long days away from home. In such cases, you can receive tax-free coverage for meals and beverages, as long as the amount does not exceed 209 kroner. This applies if the employer purchases the meals or reimburses the costs upon presenting receipts.

Overtime for people paid by the hour

Employees who are paid by the hour can receive overtime pay if they have worked normal hours of work for a full day and the overtime work is required.

Requirements for documentation and verification of overtime

See the attached memo on Requirements for satisfactory documentation and verification of overtime (PDF, in Norwegian)

Did you forget to register overtime?

You can register overtime back to the 1st of the previous month. If you have forgotten to register by the deadline, you must contact the Service center via NTNU Help.
