The number of self-employed professionals in the Netherlands is constantly changing. With the KVK ZZP monitor, you can closely follow the development of self-employed people in the Netherlands.

The total number of zzp'ers fell slightly (-0.5%) in December compared to November. On 31 December, 1,788,320 zzp'ers were registered in the Business Register, around 8,500 fewer than a month earlier. This is seen in from the KVK ZZP Monitor for December 2025. Measured in absolute numbers, the number of zzp'ers decreased mainly in the construction and health and welfare sectors. In both sectors, the decrease was approximately 2,000.

Compared to December 2024, more zzp'ers started and fewer stopped. This development deviates from the trend that was visible in recent months. The number of starters increased by approximately 800 (around 5%) compared to a year ago. The number of people who stopped decreased slightly (by 0.6%).

False self-employment checks

As of 2025, the Netherlands Tax Administration actively checks for false self-employment, where a zzp'er is in effect an employee for whom the employer does not pay employee contributions. The extra checks may have an effect on the number of zzp'ers registered in the Business Register.

All this led to a great deal of attention being paid to the growth in the number of self-employed workers in 2025. For this reason, the monitor was published every month. Now that the attention is less, we have reduced the frequency to once per quarter. The next monitor will be published in April 2026.
