Wtta: registration, the licence application and a checklist for agencies

You can register for the transitional arrangement from 1 November to 31 December 2026 on toelatinguitleenmarkt.nl. You then apply for the licence itself from 1 May to 30 June 2027. If you hold an SNA certificate with the right module that is still valid on 30 June 2027, registering is not required, but the NAU advises it.

You need eHerkenning level 3 or higher, with access to the NAU services, and a Berichtenbox voor Bedrijven whose name is registered in the KVK Business Register. Your KVK details must be correct. When you register you state your expected 2026 turnover and which application you expect to make later. You do not need a VOG to register.

Between 1 May and 30 June 2027 via toelatinguitleenmarkt.nl. You submit an inspection report (or use the SNA route) and a VOG at most 3 months old, pay the deposit (or get an exemption) and the application fee. From 1 July 2027 the NAU assesses the applications.

The deposit (waarborgsom) is €100,000. A new agency pays €50,000 on its first application. You are exempt if, on 31 December 2026, you have been registered with the KVK for 4 uninterrupted years with labour supply as a business activity, actually supplied workers in that time, and hold a valid Verklaring betalingsgedrag inlenersaansprakelijkheid (uitlener) no older than 3 months.

If you do not register, you cannot use the transitional arrangement. You then need a licence or an exemption on 1 January 2028 to keep supplying workers; otherwise you must stop. From 1 January 2028 the Netherlands Labour Authority can fine agencies without a licence and the hirers who work with them. The Wtta fine amounts have not been published yet.

For a licence with an inspection report you need: an inspection report based on the NAU standards framework (normenkader) from an inspection body designated by the NAU, a VOG at most 3 months old, the deposit (unless exempt), the application fee, and a KVK registration.

With an SNA certificate that includes the module ‘ter beschikking stellen van arbeidskrachten’ and is valid until at least 30 June 2027, you can apply once for a licence without an inspection report, provided you apply between 1 May and 30 June 2027. Registering is then not required, but the NAU advises it.

The Wtta applies to anyone who supplies workers to other businesses: staffing agencies, secondment firms and payroll companies, even as a side activity. No licence is needed within the same company, between fellow companies without profit, or between subsidiaries of one group. Recruiting without supplying workers falls outside the Wtta, says the NAU decision tree.

The application fee is the same for every agency. After (provisional) admission or an exemption you pay a yearly fee for the register, based on your turnover; the NAU gives €3,611 as the maximum for 2027. The NAU expects to set the final amounts in January 2027. On top of that comes the €100,000 deposit, unless you are exempt.

From 1 July 2027 hirers are expected to be able to check in the NAU public register whether an agency is licensed, exempt or covered by the transitional arrangement. On 1 January 2028 the KVK Waadi register moves into the NAU public Wtta register.

From 1 January 2028 the Netherlands Labour Authority can fine agencies without a licence and the hirers who work with them. The Wtta fine amounts have not been published yet; the law sets the maximum at a fifth-category fine.

Yes. The checklist on this page is also in a two-page pdf: one page for agencies, one for hirers.
