Dutch enforcement is pushing small firms to prove independence in the way work is actually done.
On a Tuesday morning, a founder looks at the planning board and sees the problem before the law enters the room. Two employees are on leave, a customer delivery is late, and the familiar zzp specialist can come in tomorrow. The invoice route feels clean. The work gets done. The month keeps moving.
The signal has to become readable
Then the question arrives from the bookkeeper, not as theory but as pressure: is this really an independent assignment, or is the company filling an ordinary staff gap with a purchase invoice? That question used to sit quietly behind the contract. It now belongs on the desk before the work starts.
The Dutch zzp shift is a move from labels to behaviour. The Netherlands is not closing the door on self-employed work. It is asking small firms and workers to make independence visible in contracts, rates, planning, tools, risk, invoices and daily conduct.
The rulebook changed shape
On 6 March 2026, Rijksoverheid announced a policy reset. The government is removing the clarification part of the VBAR bill that was meant to define when someone works as self-employed or as an employee. The legal presumption for lower-paid zzp workers remains in play, with an hourly threshold of up to €38 on the 1 January 2026 reference date.
That matters because enforcement has not paused. Belastingdienst enforcement against false self-employment fully resumed on 1 January 2025 and continues in 2026. The 2026 enforcement plan keeps part of the softer landing: no verzuimboetes and, in principle, a company visit first. Vergrijpboetes can still apply under the normal rules.
The legal floor is familiar. Belastingdienst looks at employer authority, personal work and pay. All facts and circumstances matter. The Deliveroo judgment from the Hoge Raad confirmed that status depends on the whole relationship. The Uber ruling went one step further and said entrepreneurship can matter too, but not as a single trump card.
Where the invoice touches payroll
This is why the issue belongs at the ledger and tax desk, not only with HR. If a contractor performs an assignment in employment, the client is the employer for that assignment. The company must withhold and pay wage taxes, include the worker in wage administration and report the relationship in the wage tax return.
What the signal changes
That turns a simple purchase cost into a payroll matter. Wage tax, national insurance contributions, employee insurance contributions and the income-dependent Healthcare Insurance Act contribution may enter the picture. Labour-law and pension-law risks can sit beside the tax file. A weak classification can disturb cash, pricing and records at the same time.
The worker also has a tax problem if the assignment is employment. That work is not entrepreneurial income for that assignment. Costs linked to it cannot simply be treated as business costs, and the assignment does not count for entrepreneurs' deduction, investment allowance or the mkb-winstvrijstelling. In 2026 the zelfstandigenaftrek is €1,200, with the tax benefit limited to 37.56 percent. The cushion is thinner than many older habits assume.
The market is already sorting
CBS reported that the number of zzp workers fell by 62,000 in 2025, in the context of stricter enforcement from 1 January 2025. In the first quarter of 2025, 59,000 zzp workers moved to a main job as an employee, almost twice as many as a year earlier. Most of those moves were into flexible employment.
The latest labour-market picture keeps that pressure visible. In the first quarter of 2026, CBS reported 5.6 million workers with a permanent employment relationship, 2.7 million employees with a flexible employment relationship and 1.1 million self-employed workers without staff. Flexible employment rose by 17,000 from the previous quarter, while self-employed workers without staff fell by 18,000.
KVK adds another layer. It counted 1,793,380 zzp registrations in the Handelsregister on 31 March 2026, a slight quarterly rise. Registrations can grow while main-job zzp work falls, because CBS measures people in the labour market and KVK measures register entries. The combined signal is not collapse. It is sorting.
Health and welfare deserve attention here. KVK reported the largest decrease in zzp registrations in that sector in Q1 2026. At the other end, specialist business services and ICT showed the largest absolute increases. That growth does not make those sectors low-risk by itself. Belastingdienst still assesses each relationship on its own facts.
Independence has to show up at work
Return to the founder with the planning board. If the zzp specialist works fixed hours set by the company, uses company tools, follows the same rota as staff, asks a manager for time off and carries no real commercial risk, the invoice starts to lose its story. A VAT number cannot carry that weight alone.
What founders should check
Another contractor may look different. She delivers a defined migration, sets the method, works for several clients, prices the assignment as a business result, uses her own tools, carries correction risk and can show visible entrepreneurship. That relationship has a different texture. The records and the daily work tell a more coherent story.
Model agreements still have a place, but a narrower one. Since 6 September 2024, Belastingdienst no longer assesses new model agreements and no longer extends existing ones. Agreements that were valid on that date may still be used until 31 December 2029, but only when the parties actually work as described. Paper comfort is no substitute for practice.
A calmer kind of control
For small firms, the best response is not panic and not denial. The useful habit is to look at each material zzp relationship as a business arrangement with tax consequences. Who controls the hours? Who decides the method? What is being bought: capacity, or an independent result? Does the price carry business risk, tools, downtime and reserves?
The same discipline helps the worker. A genuine independent professional needs more than a client and an invoice. Client mix, pricing, insurance, reserves, tools, acquisition time and freedom in execution all support the economic reality of entrepreneurship. Independence that cannot be seen in the work will be hard to defend later.
The government is also reshaping the wider cost base of self-employment. The announced basic disability insurance scheme for self-employed workers uses current calculations of a 5.4 percent gross premium on profit, capped at €171 per month, with implementation still taking years. It does not decide classification, but it shows the direction: zzp is being treated as a business status with its own costs, not as cheap labour packaging.
Back at the Tuesday planning board, the founder still has to deliver for the customer. That has not changed. What has changed is the quality of the decision before calling the zzp specialist. If the relationship is independent, let the work, price and records show it. If the role is really payroll work, the ledger should not pretend otherwise. Calm classification is cheaper than later reconstruction.
