Can you earn extra money by running your own business alongside your job? In most cases, yes. More and more people are starting out as zzp'ers (self-employed professionals), for example, to start small without giving up their fixed salary.
In this video, KVK presenters Max and Lisanne explain in 1 minute what you need to bear in mind:
- Check your contract: are you allowed to have a business on the side? Is there a non-compete clause?
- Discuss your plans with your employer
- Check whether you need to register with the KVK and Netherlands Tax Administration.
Good to know: even if you only work as a zzp'er for a few hours a week, you will still have to deal with matters such as records, taxes and insurance.
