Declaration tool for commuting expenses and working from home

When there is no fixed travel pattern per week, no fixed reimbursement can be granted. To these employees, reimbursement is made on a claim basis. They can submit their claim through a claim tool. More information about this tool can be found on this page. The declaration tool is available for all NWO-I employees, except for employees of NIOZ, NSCR and for BUW employees of a number of universities. For them, the declaration method applies as communicated to them.

How does the declaration tool work?

The tool has been produced by Nikhef and is hosted by Nikhef. The tool works via SURFconext. For this, you can make use of the account from your work (the password that you use to log in on your laptop).

  • Go to and follow the instructions: “Start the reimbursement request”. 
  • Choose your institute (and, after the first time, your choice will always be listed at the top), and then you can log in with the login details (credentials) of your own institute. After you have given permission for the transmission of your data, you will immediately see the form with the calendar.

You should submit declarations between the 1st and 9th of each month

Declarations must be made in retrospect, after the end of each calendar month. You should submit the declaration no later than the 9th of each month to guarantee that your declaration is paid out with your salary payment the following month.
