Time records for the Wtta
From 1 January 2027 the Wtta applies to every company that lends out workers in the Netherlands. TimeTracking supports Wtta-compliant time records: shifts are recorded with a start, end, unpaid break and work location, the client approves them, and every change keeps its old and new value.
How TimeTracking supports Wtta-compliant time records
Record complete shifts
Workers confirm a planned shift, use the timer or clock in at the kiosk, so each shift gets a start, end and break. In Wtta mode, TimeTracking refuses a shift without start, end, break or work location.
The client approves
The client contact approves the hours through a secure magic link, without an account. Their name, the time and the approved hours are saved.
Every change stays traceable
Each change keeps the old and new value and when it was made. Exported hours never change: a correction is booked in an open period, with a reason.
Hours that match payroll
Approved, payroll and paid hours side by side per worker per week, differences explained, and a Wtta dossier per worker.
What the Wtta asks of your time records
The Wtta (Wet toelating terbeschikkingstelling arbeidskrachten) brings an admission system for companies that lend out workers, such as staffing, payrolling and secondment agencies. It also covers agencies based outside the Netherlands that lend workers there. The law applies from 1 January 2027. From 1 January 2028 you may only lend out workers with an admission (toelating) from the Nederlandse Autoriteit Uitleenmarkt (NAU), and the Netherlands Labour Authority enforces that.
Applications run from 1 May to 30 June 2027, and the NAU starts assessing them on 1 July 2027. So the hours you record from January 2027 can already count. For your time records, it comes down to four things:
- Start, end, unpaid break and work location for every shift
- Approval of the hours by the client
- Changes you can trace: who changed what, when and why
- Hours that match what payroll paid out
Wtta mode: no shift without times and location
Many tools accept a total for the day, such as 8 hours. For the Wtta that is not enough. In Wtta mode, TimeTracking refuses a shift without start, end, break or work location: it cannot be submitted or approved, however the hours come in.
Client approval with a clear record
The client contact gets an email with a secure link. They check each worker's days with start and end times and breaks, and approve the week without creating an account. To confirm, they enter a one-time code from their email and type their name as a signature. Their name, the time and the exact hours they approved are saved.
If hours are still waiting, reminders go out on their own.
A change history you can show
Hours move through fixed steps: draft, submitted, approved, exported and locked. The app and the database both enforce them. Every change to a day is logged with the old and new value and when it was made.
Exported and locked hours never change. A correction is booked in an open period as a line of its own, with a reason, and goes to payroll with the next export. So your records and your payroll keep telling the same story.
Reconciliation and a Wtta dossier
TimeTracking compares three numbers per worker per week: the approved hours, the hours in your payroll run and the hours actually paid. You import the payroll journal and the payment file for that. Every difference needs an explanation, and the month-end close shows what is still open.
A Wtta dossier per worker puts the timesheet, the reconciliation, the change history and the payslips together in one PDF, ready for when an inspector asks.
What software can and cannot do
The admission covers more than time records, such as correct pay, taxes and contributions, and the right to work. TimeTracking takes care of the hours: complete shifts, approval by the client and changes you can trace. The NAU decides on the admission itself.
This page explains how TimeTracking supports Wtta-compliant time records. It is not legal advice. For the official rules, see the website of the Nederlandse Autoriteit Uitleenmarkt.
Frequently asked questions
Does TimeTracking make my agency Wtta-compliant?
No software can do that on its own. TimeTracking supports Wtta-compliant time records: complete shifts, approval by the client and a change history you can trace. For the admission, the NAU also looks at pay, taxes and more.
From when do my time records need to be complete?
The Wtta applies from 1 January 2027, and enforcement starts on 1 January 2028. Hours from 2027 can already count in the assessment, so record complete shifts from January 2027.
What happens to a client timesheet with only day totals?
In Wtta mode, rows with only a total for the day go to review instead of being booked. Your office then adds the start, end and break, or asks the client for them.
Can workers still log their hours quickly?
Yes. They confirm a planned shift, use the timer or clock in at the kiosk. The timer and the kiosk record the start and end of the shift.
