The Dutch staffing compliance stack: Wtta, Wet DBA, pay transparency and the AI Act
Between now and January 2028, every staffing firm operating in the Netherlands faces four regulatory waves, each with its own date. Individually they are manageable; stacked, they define what your administration, files and systems must look like. This is the agenda, and what it means for how your firm is built.
The agenda: four waves, four dates
Wet DBA, since 2025
The Dutch tax authority enforces against false self-employment again. The effect is visible in the numbers: work is flowing back from contractor constructions towards employment and agency constructions, with heavier documentation requirements (source: Flexmarkt, 2026).
Pay transparency, from mid August 2026
The first Dutch rules under the European pay transparency directive land. Candidates gain the right to salary information before the interview, and firms must answer pay questions with data rather than estimates.
Wtta, in three steps
The registration window at the admitting authority opens 1 November 2026 and closes 31 December 2026. The admission regime applies from 1 January 2027: providers of labour need admission under the normenkader, with certificate of conduct and security deposit, and hirers may only work with admitted providers. The Labour Inspectorate enforces from 1 January 2028, with fines on both sides (source: ABU; Eerste Kamer, dossier 36.446).
EU AI Act, with a fixed date for the sector
Transparency obligations have applied since 2 August 2026. High-risk obligations for standalone AI systems, with candidate matching as a named example, take effect on 2 December 2027. Anyone using AI in recruitment must then demonstrate human oversight, logging and explainability.
What the stacking means
Each wave on its own is a project. Stacked, they become something else: a continuous burden of proof. From 2027 you must be able to show, at any moment, that your administration is correct (Wtta), your pay is explainable (transparency), your working relationships are properly qualified (DBA) and your AI runs under demonstrable human oversight (AI Act). Keep that evidence in folders, mailboxes and loose spreadsheets, and every audit becomes a manual project. Keep it in the platform where the work already happens, and an audit becomes a report.
From file factory to report
For firms on a Salesforce foundation (Byner, Mysolution, a Salesforce edition of Bullhorn, or Salesforce alongside), the route is concrete. Certificates, clearances and contracts belong as structured data on the placement, not as attachments in a mailbox. Expiry dates should be signals, not surprises. And the agent layer makes it continuous: a compliance agent that keeps files current, flags missing pieces and writes the audit trail, prepared by software, reviewed by people, recorded traceably.
The order of action
First the registration window: filing between 1 November and 31 December 2026 is the cheapest insurance available. Then lay the normenkader next to your current administration and name the gaps. Then move file-keeping into the platform, so 2027 is not a rebuild. And if you are building AI support in recruitment or matching now: build with human oversight and logging from day one, and 2 December 2027 becomes a date instead of a deadline.

An admission regime for everyone providing labour: no admission from 2027 means no providing, and hirers may only work with admitted parties.
When must my firm register?
The registration window runs from 1 November to 31 December 2026; the admission application period runs from 1 May to 30 June 2027 (source: ABU).
Does the Wtta also cover secondment and payrolling?
Yes, the regime covers the broad provision of labour, not only classic temporary staffing.
What changes under the pay transparency directive?
Candidates gain the right to pay information before the interview, and pay differences must be explainable with data.
Does AI candidate matching fall under the AI Act?
Yes, candidate matching is explicitly named among high-risk systems; those obligations apply from 2 December 2027.
What is the first step for a firm reading this?
Put the registration window in the calendar, then plan one session to lay the normenkader next to your current administration. We are glad to do that second part with you.
