A practical checklist based on the steps the NAU itself publishes on toelatinguitleenmarkt.nl. Work through it now: getting your operations in order takes time.

Updated 24 October 2026

New to Dutch rules? The Wtta (Wet toelating terbeschikkingstelling van arbeidskrachten, the Placement of Personnel Admission Act) is a Dutch law that requires every business that supplies workers to other companies in the Netherlands to hold an admission from the Dutch Labour Market Admission Authority (NAU). Official sources are mostly in Dutch, so we link to them and summarise them in English.

1. Digital essentials (before 1 November 2026)

☐ eHerkenning level 3 (or higher) requested
☐ Berichtenbox for businesses created and its name registered in the Business Register
☐ NAU service enabled in your eHerkenning provider's service catalogue
☐ KvK details correct and complete

2. Pay and terms of employment

☐ You check which collective agreement (CAO) applies at the client and apply it
☐ At least the statutory minimum wage and holiday pay
☐ Overtime, allowances and holiday pay paid correctly
☐ No unspecified “all-in” wage
☐ Equal pay compared with similar roles at the client
☐ Terms of employment given to employees in writing (new)

3. Taxes and contributions

☐ Payroll taxes and contributions paid on time and correctly
☐ Rules on sickness and incapacity applied
☐ Records match what you pay

4. Staff and time records

☐ Clear overview of which employees you supply to which clients
☐ Hours with start and end times, linkable to payslips
☐ Contracts and identity details kept
☐ Only employees who are allowed to work in the Netherlands
☐ Clients told in advance which employees you supply
☐ Records kept for at least 7 years

5. Housing (if you provide it)

☐ SNF certification, or housing via a housing association
☐ Written tenancy agreement
☐ Employment contract and tenancy agreement clearly separate

6. Inspection, VOG and deposit

☐ Route chosen: SNA certification, Wtta inspection report, provisional admission or exemption
☐ In contact with an accredited inspection body (see the NAU register)
☐ Plan for the €100,000 security deposit
☐ Only request a VOG for legal entities when the NAU says so
