Working in the Netherlands? Your Dutch client wants your notification and proof before you start
You notify your workers in the Dutch posting portal (meldloket) before the first working day. Your client checks the notification no later than five working days after the start, checks the ID and right to work of every worker, and is liable for your wage tax and your workers' wages. That is why they ask for this proof before the start and often before the first payment.
or try the free check first (2 min)Do-it-yourself software: you and your client each handle your own part, in your own language. The app prepares, watches the dates and checks the uploads.

What is due when
- 1
At the contract
- Contract describing the work and the period
- Extract from your trade register
- For hiring out staff: your KVK registration (Waadi)
- Dutch subcontractors: trade register extract (KVK), payment-behaviour statement (verklaring betalingsgedrag), g-rekening agreement, man-day register; they do not notify in the meldloket
- 2
Before the first working day
- Notification in the portal
- A1 for each worker
- ID and right to work of every worker
- Contact person in the Netherlands
- 3
No later than five working days after the start
- Your client checks your notification in the portal
- Again after every change
- 4
Before the first invoice is paid, and at every invoice after that
- "btw verlegd" on the invoice
- Man-day register (mandagenregister)
- If you owe Dutch wage tax: payment-behaviour statement (verklaring betalingsgedrag) and payment into the blocked account (g-rekening)
If you use subcontractors yourself, you are their client: you check their notification and their people's IDs, and you are liable for their wages.
For companies that send their own people to the Netherlands
Construction companies working as subcontractors
Structural work, fit-out and assembly on Dutch sites, for a Dutch main contractor.
Main contractors with their own subcontractors
You are a subcontractor and a client at the same time: you notify, you check, you are liable.
Installation firms in construction
Electrical, heating and ventilation work on site: notification from day one.
Two sides of the same job. The software prepares both, each in its own language
You, the foreign company
- Notify your workers before the start in the portal, in English, German or Dutch. Self-employed people in construction notify themselves too. Exception: first assembly of a supplied machine up to 8 days, not in construction, EU fitters only.
- Apply for the A1 certificate for each worker in your home country.
- Name a contact person who is present in the Netherlands.
- Pay by Dutch rules: at least the wage in the cao Bouw & Infra (the Dutch construction collective agreement) or the statutory minimum wage, plus working hours and holidays. Statutory minimum wage from 1 July 2026: €14.99 gross per hour (age 21 and over), plus 8% holiday allowance; collective-agreement wages are usually higher.
- Keep documents ready at the workplace: contracts, payslips, time records, A1 and proof of payment, and keep them for five years after the job ends.
Your Dutch client
- Tells you about the notification duty and gives their e-mail address for the check.
- Checks your notification (where a notification is required) in the portal, no later than five working days after the start. Again after every change.
- Checks identity and right to work of everyone on site, before the start.
- Limits their chain liability by asking for a contract, a man-day register, a payment-behaviour statement and payments into your blocked account.WKA
- Hiring out staff? Then they check your KVK registration before the start.Waadi

Whole chain
Your client is liable for your Dutch wage tax and for your workers' wages. That is why they often ask for the payment-behaviour statement and payments into your blocked account.
