Hiring in the Netherlands means taking on a well-defined set of payroll obligations. The Dutch system layers income tax withholding on top of several social security contributions, and the rates vary depending on contract type, sector, and the employee’s salary level. If you’re a foreign company setting up payroll for the first time, understanding what you owe before your first hire saves you from expensive corrections later. This guide breaks down every major employer-side cost, explains how income tax withholding works, and covers the 30% ruling that applies to many international hires.
Registration requirements before you hire
Before running your first payroll in the Netherlands, you need to complete two registrations. First, register with the Belastingdienst (Dutch Tax Authority) to obtain a payroll tax number. Second, register with UWV (the Employee Insurance Agency), which administers most of the social insurance funds covered in this guide. Both registrations need to be in place before your first payroll run. Operating without them exposes you to penalties and back-payments, so don’t leave this until the last minute.
Social security contributions: what employers pay
The Netherlands funds its social insurance system through a set of employer contributions, each tied to a specific scheme. Most apply up to a maximum social security income base of approximately €69,395 per year in 2026. Earnings above that threshold aren’t subject to these contributions.
Here’s a breakdown of the main employer-side levies.
Zvw: healthcare insurance contribution
The Zvw (Zorgverzekeringswet, or Healthcare Insurance Act) has two components. Employers pay a levy of 6.10% on the employee’s wages. Separately, employees pay their own contribution of 4.85%, but this is withheld and remitted by the employer through payroll. Both rates apply up to the maximum income base of approximately €69,395. Above that threshold, no Zvw is due.
Awf: unemployment fund contributions
The AWf (Algemeen Werkloosheidsfonds) rate depends on the contract type:
- Permanent contracts: 2.74%
- Temporary or flexible contracts: 7.74%
This rate difference is one of the strongest financial incentives in Dutch law to offer permanent contracts. If an employee on a temporary contract works more than 30% overtime in a year, the employer may owe the higher rate retroactively, so it’s worth monitoring hours carefully.
Aof: disability fund contributions
The Aof (Arbeidsongeschiktheidsfonds) covers long-term disability insurance under the WIA (Work and Income according to Labour Capacity Act). The rate is:
- Low rate: 6.26% (for smaller employers)
- High rate: 7.61% (for larger employers, sector-dependent)
Which rate applies to you depends on your company’s size and sector classification. UWV determines this when you register.
Whk: work resumption fund
The WHK (Werkhervattingskas) is a differentiated premium ranging from 0.21% to 3.48%. Unlike the other contributions, the WHK rate is directly tied to your company’s claim history. Employers with few sick or disabled employees returning to the workforce pay less. Employers with a higher claims history pay more. This makes the WHK a variable that’s hard to predict when you first start hiring, but it stabilises over time as your track record is established.
Childcare surcharge
Employers also pay a childcare surcharge (kinderopvangtoeslag opslag) of 0.50% on taxable wages. This funds the national childcare subsidy system. It applies regardless of whether any of your employees use subsidised childcare.
Total employer on-cost
Adding the contributions above, the total employer on-cost typically falls between 13% and 25% of gross salary, depending on contract type, sector, and the WHK differentiated rate. Permanent-contract employees in lower-risk sectors sit toward the lower end of that range. Flexible-contract employees in higher-risk sectors push toward the top.
Income tax withholding: how loonheffing works
Employers in the Netherlands are responsible for withholding and remitting income tax through the payroll tax system (loonheffing). This is filed monthly with the Belastingdienst. The 2026 Box 1 tax brackets are:
| Taxable income | Rate |
|---|---|
| Up to €38,883 | 35.75% |
| €38,883 to €78,426 | 37.56% |
| Above €78,426 | 49.50% |
These are progressive rates applied to each slice of income, not a flat rate on total income. Most employees also benefit from the general tax credit (algemene heffingskorting), which has a maximum value of €3,115 in 2026. This credit phases out for income above €29,736, so higher earners receive a reduced credit or none at all. Payroll software handles the phaseout calculation automatically, but it’s worth knowing the credit exists since it affects net pay meaningfully for lower and mid-range salaries.
The 30% ruling for expat employees
If you’re hiring international talent, the 30% ruling (30%-regeling) is one of the most significant tax provisions to understand. Under this ruling, eligible expat employees can receive 30% of their gross salary as a tax-free reimbursement for extraterritorial costs, effectively reducing their taxable income. The employer administers this through payroll.
Eligibility requirements
To qualify, the employee must be recruited from abroad, possess specific expertise that’s scarce in the Dutch labour market, and meet a minimum taxable salary threshold. In 2026, that threshold is:
- General: €48,013 per year (after applying the 30% reduction to gross salary)
- Under 30 with a qualifying Master’s degree: €36,497 per year
The 30% exclusion is capped based on a maximum salary of €262,000. Any portion of salary above that level doesn’t benefit from the ruling.
Rate and timeline
The ruling currently applies at a flat 30% rate throughout 2026. That’s scheduled to change: from January 1, 2027, the rate reduces to 27%. If you have employees currently benefiting from the ruling, it’s worth flagging this change in your planning.
One further point on transitional rules: employees who were already in the 30% ruling as of December 2022 became subject to an income cap starting January 1, 2026. If any of your employees fall into this group, confirm with your payroll provider that the cap is being applied correctly.
Putting it together: a practical overview
Here’s a quick reference for what an employer is typically responsible for in the Netherlands:
- Registering with both Belastingdienst and UWV before the first hire
- Withholding and remitting loonheffing monthly, applying the correct tax brackets and credits
- Paying Zvw employer levy (6.10%), AWf (2.74% or 7.74%), Aof (6.26% or 7.61%), WHK (0.21% to 3.48%), and childcare surcharge (0.50%)
- Applying the 30% ruling via payroll for eligible expat employees
- Monitoring social security contributions against the €69,395 annual income cap
Total employer on-costs of 13% to 25% on top of gross salary are the realistic planning range. The actual figure for your workforce depends on the mix of contract types, your WHK claim history, and your sector classification.
Working with an EOR in the netherlands
If your company doesn’t have a Dutch legal entity, you can’t run payroll directly. One practical route is to engage an Employer of Record (EOR), which acts as the legal employer of your Netherlands-based staff on your behalf. The EOR handles registration, payroll tax filing, social security contributions, and compliance, while your team member works day-to-day under your direction. For companies testing the Dutch market or hiring a small number of employees, this avoids the cost and complexity of setting up a local entity. When comparing providers, look carefully at what’s included in the EOR services fee and whether the 30% ruling can be administered through the platform.
FAQ
What’s the difference between the low and high AWf rate, and when does it switch?
The low AWf rate of 2.74% applies to employees on written, open-ended (permanent) contracts. The high rate of 7.74% applies to temporary or flexible contracts. The high rate can also apply retroactively if an employee on a permanent contract works more than 30% overtime in a calendar year, so employers should track this threshold.
Does the 30% ruling reduce the employer’s social security contributions?
No. Social security contributions are calculated on the full gross salary, not the reduced taxable salary. The 30% ruling reduces the employee’s taxable income for loonheffing purposes, but the employer-side levies still apply to the full wage bill.
When do social security contributions stop applying within a year?
The major social security contributions, including Zvw and AWf, apply only up to the maximum income base of approximately €69,395 per year. Once an employee’s cumulative wages in a calendar year exceed that threshold, no further social security contributions are due on the excess. High earners cross this ceiling partway through the year, which reduces the employer’s marginal cost on their remaining salary for that year.
Can a foreign company run Dutch payroll without a local entity?
Not directly. Dutch payroll tax registration requires a legal presence in the Netherlands. Foreign companies that want to hire Dutch employees without establishing a local entity typically do so through an Employer of Record, which holds the required registrations and employs the staff on the foreign company’s behalf.
