A zero-hour start may be lawful, but it can still fail the 30% facility before the specialist settles in.
A hiring file is never neutral. The first document sets the story that payroll, tax, HR and management later must defend. Recently, Rechtbank Noord-Holland showed how strict that document can be for a Dutch employer seeking the 30% facility. Therefore, Dutch employment contracts should be read as evidence, not only as policy.
Dutch employment contracts: capacity first
The court decided the case on 5 February 2026 and published it under ECLI:NL:RBNHO:2026:2541. The employee already had a 30% facility decision with a previous employer, running from 6 November 2023 to 5 November 2028. At the new employer, the employee started on 22 July 2024 under a zero-hour contract with an hourly wage of €32.37 and no guaranteed minimum working time.
For Dutch employment contracts, the contract, roster, payroll file and cash bridge must tell the same story.
A fixed contract followed on 13 August 2024, with a gross monthly salary of €3,909. However, the Belastingdienst refused the request to apply the facility at the new employer. The court upheld that refusal. It held that the wage requirement had to be tested at the start of the new employment relationship. At that moment, there was no fixed agreed wage.
The first contract sets the tax test
For a small employer, that outcome feels harsh. The later contract arrived within weeks. Moreover, the role may have been serious, and the employee may have expected continuity. Yet the court looked at the start date. It did not treat the first contract as a harmless bridge. Instead, that contract anchored the tax test.
That is the HR lesson. A zero-hour contract can be lawful under Dutch labour rules. Rijksoverheid describes it as an employment contract without agreed working hours, where the employer pays for hours worked. Because a call worker has no fixed monthly wage, the form was weak for the 30% facility.
The 30% facility is not just a payroll benefit. It is a controlled file. The employee must meet the conditions, including specific expertise. Also, the Belastingdienst must issue a decision. When an employee changes employer, the new employer and employee must submit a new request if the facility is to continue. Specific group or transfer rules may change that requirement.
Availability becomes a cost
In 2026, the general income norm for specific expertise is more than €48,013 in taxable annual wage, excluding the specific exemption. For employees under 30 with a Dutch academic master's degree or equivalent foreign title, the 2026 norm is €36,497. Those figures are practical, not abstract. Therefore, the wage must be testable from the start.
Flexible work and tax eligibility differ
This is where many small employers need to pause. Flexible work is normal in the Netherlands. CBS counted about 2.7 million employees with a flexible employment relationship in the first quarter of 2026. Together, flexible workers and self-employed persons without personnel amounted to about 3.9 million workers, or four out of ten.
However, flexible hiring and tax eligibility do not always fit together. A contract can be acceptable for one purpose and fragile for another. Labour law may allow a certain form. Still, payroll tax may require a fixed, measurable wage at a precise moment. In practice, that difference can decide whether a recruitment promise survives the administration file.
Imagine a small technical firm that has finally found a foreign engineer. The founder wants the person to start quickly. Yet HR capacity is thin. So a zero-hour contract is used for the first weeks, with the fixed contract to follow after internal paperwork. Everyone thinks the real agreement is clear. However, the file says something else.
It shows no guaranteed hours, no fixed monthly wage and no testable annual wage at the start. That is not a paperwork detail. It is a governance issue. The company story and the signed document must match. If management calls the person a specialist hire with a stable salary, the first contract should not tell the opposite story. When the file contradicts the commercial explanation, the file usually wins.
The payroll promise has a cash side
The 30% facility can allow a tax-free reimbursement of up to 30% of the wage, including extraterritorial costs, within the conditions. In 2026, the maximum tax-free reimbursement is €78,600. Alternatively, the employer may reimburse actual extraterritorial costs tax-free if those costs can be proven. There is an annual choice between the two routes.
Therefore, the Dutch employment contracts question depends on records, wage declarations and employer decisions that can survive review.
For an owner-managed company, the practical issue is not only tax language. It is the net pay conversation. When a specialist expects a certain net outcome, and the file cannot support the facility, pressure may follow. Then the employer may have to revisit gross pay, cost reimbursement, or the whole package. That pressure lands in cash flow and trust.
What small employers should map
There is also an annual control problem. During the term of the decision, the employer has to test whether the employee still meets the income norm. If the wage in a year falls below the indexed norm, the facility lapses retroactively to 1 January of that year. Earlier payroll tax returns must then be corrected. So payroll cannot treat approval as permanent comfort.
This matters more as the rules tighten. Rijksoverheid states that the maximum remains 30% in 2025 and 2026, but is reduced to 27% from 2027. Transition rules depend on when the facility first applied. From 2027, a higher salary threshold will also apply. Thus, timing, first use and contract quality now sit in the same control file.
Dutch policy is moving toward fixed baselines
I read this ruling as part of a wider Dutch movement toward documented baselines. On 12 May 2026, the Tweede Kamer adopted the bill for more security for flexible workers. If the Eerste Kamer agrees, entry into force can follow on 1 January 2028. The proposal replaces zero-hour contracts with bandwidth contracts, built around agreed minimum and maximum hours.
That future reform is not the reason for the court's decision. Still, the direction is visible. Dutch HR is being pushed toward clearer scope, clearer wage commitments and files that reconcile before work starts. The same pressure appears in payroll tax. After all, a vague start can be convenient on Monday and expensive when the request is assessed.
For a small employer, the discipline is modest but serious. Before the start date, the offer letter, employment contract, salary norm, payroll setup and 30% request should tell one story. If the employee is changing employer and continuity of the facility is expected, the first contract deserves special attention. A bridge contract is not harmless when it becomes the legal start.
This is not a warning against hiring foreign specialists. Rather, it warns against casual onboarding when the benefit depends on exact conditions. The entrepreneur remains free to move quickly. However, speed needs a better file. In this case, the later fixed contract came too late to repair the first step.
The first signature carries the burden
The quiet lesson is useful beyond the 30% facility. HR documents are not only employee relations documents. They are tax documents, payroll documents and evidence documents. In a small company, one person may handle recruitment, salary, contracts and payroll contact. That makes the first signature unusually important.
A good hire starts with trust. However, a safe hire starts with a file that can carry that trust. When the first contract is weak, the business may spend the rest of the relationship explaining what it meant. The court has now reminded employers that meaning is not enough. At the start, the document has to do the work.
