If you have a business in the Netherlands that owns a company car, you have certain obligations regarding motor vehicle tax, periodic motor vehicle tests and car insurance. However, if you want to stop using your company car for a longer period of time, you may decide to suspend your business vehicle registration (in Dutch).
You can do this digitally via an RDW-certificate or your DigiD and Chamber of Commerce number. Instead, you may prefer to contact the Netherlands Vehicle Authority (in Dutch) directly or a vehicle registration certificate office. You pay a fee to have the registration suspended. A suspension starts immediately and lasts up to one year. You can always decide to extend its duration.
