WBA: Online employment relationship evaluation tool

This information is provided by |

You want to hire a self-employed professional to do a job for you. Whether or not you are allowed to hire someone externally depends on the employment relationship. To evaluate the employment relationship, you can use an online questionnaire. This pilot project from the Dutch government is called the Web Module Assessing Employment Relationships (Webmodule Beoordeling Arbeidsrelatie, WBA, in Dutch). This article explains how it works.

Hiring a self-employed professional comes with rules. To clarify these rules, the government has developed an anonymous, online questionnaire.

Completing all the questions in the tool will produce one of the following results:

  • Indication that the assignment can be performed by a self-employed professional, outside employment.
  • Indication that the employment relationship is actually a form of employment.
  • The replies do not make clear what the work relation is in this case.

No legal decision

During the pilot phase and its current aftermath, the outcome of the online tool is merely an indication, not a legal decision. You cannot make any legal claims based on the outcome. But the outcome can help you decide how to have the assignment carried out.

Who can use the online tool?

Employers and procurers in the Netherlands who set out assignments to contractors in the Netherlands.

The online tool is not for contractors or sector representatives, unless they act in the role of procurer. If you enter into an agreement with a legal entity, the online tool will not give a result. Nor if you act as an intermediary or mediator.

About the tool

The Webmodule Beoordeling Arbeidsrelatie tool was first made available as a pilot. The pilot phase helps to improve the web module. In July 2021, this research period ended. However, it is still possible to use the web module.

Help to improve

The online tool will be evaluated before the decision to go ahead is made. To gather information for this evaluation, you will be asked to contribute to a survey on how the tool works before you see the result. Your user experience will help to decide if the tool will be implemented. All responses are welcome, even after the end of the survey period.

Questions or more information

Read more about why the pilot was initiated in this press release (in Dutch) or read the news item concerning the House of Representative's evaluation of the web module pilot (in Dutch). If you would like to know more about the questions in the web module in advance, you can consult the complete questionnaire as a PDF file attached to the press release.

If anything in the questionnaire is unclear, you can send an email to The questions in the online tool are based on the information you provide about the assignment.

Using the online tool

To start the questionnaire, open the online tool (in Dutch).

You cannot save your replies in between questions. Make sure you have enough time to fill out all questions in one go. If you have to pause the questionnaire, don’t close the window. You can resume filling out the tool later on. If you close the window (by clicking the x in the top right hand corner), the session will be terminated and you will have to start over.
