Wtta knowledge base

Practical explanations of the Dutch Placement of Personnel Admission Act (Wtta), in English, based on official Dutch sources.

The Wtta (Wet toelating terbeschikkingstelling van arbeidskrachten) makes admission mandatory for every business that supplies workers to other companies in the Netherlands. It enters into force on 1 January 2027 and is enforced from 1 January 2028. Most official information is only available in Dutch; these articles summarise it and link to the sources.
