Introduction
The free movement of workers within the European Union enables employees of foreign EU companies to perform work in the Netherlands. Whether it concerns a Polish construction company, a German technology firm, or a French consulting agency – the possibilities exist. But what exactly are the conditions? And which rules apply to posting? In this comprehensive blog, we discuss all legal aspects of employing workers from foreign EU companies in the Netherlands.
Free Movement of Workers: A Fundamental EU Right
The free movement of workers is one of the four freedoms on which the European Union is built. This means that workers from all EU member states have the right to work in the Netherlands without discrimination based on nationality. This right is enshrined in EU Regulation 492/2011 and forms the legal basis for cross-border employment within Europe.
For employees of, for example, a Polish, Romanian, or Bulgarian company, this means they can work in the Netherlands without an employment permit. This is an important difference from workers from countries outside the EU, who do need a work permit.
Posting: When Does It Apply?
Posting means that an employee is temporarily sent by their foreign employer to the Netherlands to perform work there, while the employment contract with the foreign employer remains in effect. This is common in sectors such as construction, transport, technology, and consultancy.
Posting occurs when:
- The employee has an employment contract with a foreign company
- The employee temporarily performs work in the Netherlands
- The foreign employer continues to exercise supervision and management over the employee
- There is genuine economic activity in the country of origin
It is important to distinguish posting from other forms of cross-border employment, such as hiring self-employed persons or establishing a Dutch branch.
The Notification Requirement: A Crucial Obligation
One of the most important obligations for foreign employers who post workers to the Netherlands is the notification requirement. This obligation is laid down in the Working Conditions for Posted Workers in the European Union Act (WagwEU).
What Does the Notification Requirement Entail?
The foreign employer must submit a notification to the Dutch authorities before the work commences. This notification must contain the following information:
- Identity of the employer and any contact person in the Netherlands
- Expected duration of the posting
- Identity of the posted workers
- Location where the work will be performed
- Nature of the services to be provided
- Proof that the workers are legally employed
The notification can be made digitally via the Posted Workers Notification Portal. It is essential that this notification is made correctly and in a timely manner, as non-compliance can lead to substantial fines.
Sanctions for Non-Compliance
In case of non-compliance with the notification requirement, a foreign company risks an administrative fine. The maximum fine is €23,750 per violation. For repeated violations within five years, the fine can be doubled or even tripled. The Dutch Inspectorate SZW (Social Affairs and Employment) actively enforces this regulation.
Case law has confirmed that these fines are actually imposed. In one case, a fine of €240,000 was imposed for 30 violations, which was later reduced to €237,500 due to exceeding reasonable time limits. This shows that the Dutch authorities take the notification requirement seriously.
Which Employment Conditions Apply?
A frequently asked question is: which employment conditions apply to posted workers? Dutch law or the law of the country of origin?
Core Employment Conditions
Under the Posting Directive (96/71/EC, amended by Directive 2018/957), Dutch core employment conditions apply to posted workers from the first day of posting. These core employment conditions include:
- Minimum wage and minimum holiday allowance
- Maximum working hours and minimum rest periods
- Minimum number of holiday days (at least 20 per year for full-time employment)
- Working conditions and occupational safety
- Equal treatment of men and women
- Protection of pregnant workers and mothers
- Protection of children and young people
This means that a Polish worker posted to the Netherlands is entitled to at least the Dutch minimum wage, even if the Polish wage would be lower.
Collective Labor Agreement (CLA) Provisions
If a universally applicable collective labor agreement (CLA) applies in the sector in which work is performed, the provisions of this CLA also apply to posted workers. This applies from the first day of posting. Examples of sectors with universally applicable CLAs include:
- Construction and infrastructure
- Temporary employment sector
- Metal and technology
- Cleaning
- Transport
CLA provisions may relate to higher wages than the statutory minimum wage, additional allowances (such as overtime, irregular hours allowance, travel allowance), and other employment conditions.
Long-Term Posting: More Obligations
If the posting lasts longer than 12 months (or 18 months with justified extension), almost all employment conditions applicable in the Netherlands for comparable workers apply. This means that after this period, conditions such as pension schemes and termination procedures may also apply.
Social Security: Which System Applies?
Another important aspect is the question of which social security system applies: the Dutch system or that of the country of origin?
The General Rule
For posting up to 12 months, the social security system of the country of origin generally continues to apply. This means that the worker pays social security contributions in, for example, Poland and is also entitled to social benefits there, such as sickness benefit and unemployment benefit.
To prove this, the employer must request an A1 certificate (formerly E101 certificate) from the social security institution in the country of origin. This certificate proves that the employee is covered by the social security system of the home country and therefore not by the Dutch system.
Extension
If the posting lasts longer than 12 months, an extension can be requested for a maximum of 24 months. After this period, the worker is usually subjected to the Dutch social security system.
Exceptions
There are situations in which the Dutch system applies directly, for example when:
- The worker works simultaneously in multiple countries
- There is no genuine posting
- The employer has no substantial activities in the country of origin
Tax Aspects: Payroll Tax and Income Tax
In addition to social security, the tax position also plays an important role.
Payroll Tax
If a posted worker works in the Netherlands, the employer is in many cases obliged to withhold and remit Dutch payroll tax (wage tax and national insurance premiums). This particularly applies if:
- The worker works in the Netherlands for more than 183 days per year
- The employer has a permanent establishment in the Netherlands
- The costs are borne by a Dutch entity
Tax Treaties
For shorter postings, tax treaties between the Netherlands and the country of origin may determine that no Dutch payroll tax is due. These treaties often have a 183-day rule: if the employee is in the Netherlands for less than 183 days and the costs are not borne by a Dutch employer, no Dutch payroll tax needs to be withheld.
It is important to assess the tax obligations on a case-by-case basis, as incorrect remittance can lead to back taxes and fines.
The Risk of False Self-Employment
An important point of attention when deploying foreign workers is the risk of false self-employment. False self-employment occurs when someone formally works as a self-employed person but actually performs work in an employment relationship that qualifies as an employment contract.
When Is There False Self-Employment?
The Dutch court applies the following criteria to assess whether there is an employment contract:
- Personal work obligation: must the worker do the work themselves?
- Authority relationship: does the client give instructions and exercise supervision?
- Wage payment: does the worker receive regular payment?
If these three criteria are met, then according to Dutch law there is an employment contract, even if the parties have called it something else.
Consequences of False Self-Employment
If it turns out afterwards that there was false self-employment instead of genuine posting or self-employed work, the consequences can be far-reaching:
- Back payment of payroll tax and premiums: The Tax Authority can impose back taxes on payroll tax and premiums up to five years back, including fines and interest.
- Employment law consequences: The worker receives all rights of an employee, such as dismissal protection, right to continued payment during illness, and notice periods.
- Chain liability: Not only the formal employer but also the client can be held liable for outstanding wages and premiums (chain liability).
- Fines for violation of the DBA Act: Fines can be imposed for violation of the Deregulation Assessment of Employment Relationships Act.
How to Prevent False Self-Employment?
To prevent false self-employment when deploying foreign workers:
- Ensure clear written employment contracts
- Carefully document the posting
- Have the foreign employer actually give direction
- Avoid direct instructions to posted workers
- Arrange for an A1 certificate
- Comply with the notification requirement
- Have an analysis made of the employment relationship in case of doubt
Inspection and Enforcement
The Dutch Inspectorate SZW actively enforces the regulations regarding posted workers. Inspectors can visit workplaces and request documents at any time.
What Does the Inspectorate Check?
During an inspection, the following matters are checked, among others:
- Has the notification requirement been complied with?
- Are the Dutch core employment conditions being complied with?
- Is there a valid A1 certificate?
- Are the CLA provisions being complied with?
- Is there genuine posting or sham constructions?
- Are identity documents and employment contracts available?
Documents That Must Be Available
During the posting, the employer and employee must be able to present the following documents:
- Employment contract
- Payslips
- A1 certificate
- Proof of payment of social security contributions in the country of origin
- Proof of notification requirement
- Copy of identity document
It is advisable to always have these documents at hand at the workplace, as a fine can be imposed immediately if they cannot be presented.

Frequently Asked Questions about Foreign EU Workers in the Netherlands
1. Do workers from Poland need a work permit to work in the Netherlands?
No, Polish workers do not need a work permit. Due to the free movement of workers within the EU, they may work in the Netherlands without an employment permit. This applies to all EU citizens.
2. What is the difference between posting and regular employment?
With posting, the worker remains employed by the foreign company and is temporarily sent to the Netherlands. With regular employment, the worker is directly employed by a Dutch company. The main differences are in social security (A1 certificate) and the notification requirement.
3. As a foreign employer, must I always submit a notification?
Yes, if you post workers to the Netherlands for more than a few days, you are required to notify this in advance via the Posted Workers Notification Portal. This must be done before work begins.
4. What happens if I forget the notification requirement?
In case of non-compliance with the notification requirement, a fine of up to €23,750 per violation can be imposed. For repeated violations, this fine can be doubled or even tripled. The Inspectorate SZW actively enforces this.
5. What minimum wage must I pay posted workers?
You must pay at least the Dutch statutory minimum wage. If a universally applicable collective labor agreement (CLA) applies in the sector, you must pay the (often higher) CLA wage. The minimum wage is adjusted annually on January 1 and July 1.
6. What is an A1 certificate and why do I need it?
An A1 certificate (formerly E101) proves that the worker is covered by the social security system of the country of origin and not by the Dutch system. This prevents double premium payment. You request this from the social security institution in your country.
7. How long can I post workers to the Netherlands?
In principle, you can post workers for up to 12 months under the social security system of your country. This can be extended once to 24 months. After that, the Dutch system usually applies.
8. Do Dutch CLAs also apply to my posted workers?
Yes, if a universally applicable CLA applies in the sector, the main provisions are mandatory for your posted workers from day one. This includes wages, allowances, and working hours, among other things.
9. Must I withhold and remit Dutch payroll tax?
This depends on the duration of the posting and the tax treaties between the Netherlands and your country. For shorter postings (under 183 days), Dutch payroll tax is often not due. For longer postings or if you have a permanent establishment in the Netherlands, it is.
10. What is false self-employment and why is it a problem?
False self-employment means that someone formally works as a self-employed person but actually has an employment contract. This can lead to back payment of taxes and premiums, fines, and employment law claims. The Tax Authority can impose back taxes up to five years.
11. Which documents must I have available at the workplace?
You must always be able to present: employment contract, payslips, A1 certificate, proof of notification requirement, identity documents, and proof of payment of social security contributions in the country of origin. The Inspectorate SZW can request these at any time.
12. Can I also hire temporary workers from abroad?
Yes, but then specific rules for temporary employment apply. The foreign employment agency must comply with Dutch regulations, including the ABU or NBBU CLA, and the temporary worker has the same rights as Dutch temporary workers.
13. What are the consequences if my worker works in the Netherlands for longer than 12 months?
After 12 months (or 18 months with extension), all Dutch employment conditions apply, not just the core conditions. Social security can also transfer to the Dutch system if no extension of the A1 certificate has been obtained.
14. May I dismiss a posted worker during the posting?
That depends on the applicable law. In principle, the dismissal law of your country applies. But after long-term posting, Dutch dismissal rules may become applicable. Legal advice is advisable in case of doubt.
15. What should I do if I receive a fine from the Inspectorate SZW?
You can object to the fine within six weeks. In the objection letter, you must explain why you believe the fine is unjustified or too high. It is advisable to engage legal assistance for this.
16. Are my workers entitled to Dutch vacation days?
Yes, posted workers are entitled to at least the Dutch minimum of 20 vacation days per year (for full-time employment). If the CLA prescribes more days, that number applies.
17. As a client, must I arrange anything or is that the responsibility of the foreign employer?
As a client, you have no direct notification obligation, but you are jointly responsible. You can be held liable if the foreign employer violates the rules (chain liability). Therefore, always check that the employer complies with all obligations.
18. Can a posted worker claim a Dutch unemployment benefit?
No, if the worker is covered by the social security system of the country of origin (A1 certificate), they are entitled to unemployment benefit there. Only if the worker is covered by the Dutch system can they claim Dutch unemployment benefit.
19. What if my worker becomes ill in the Netherlands?
In case of illness, the wage payment obligation continues according to the rules of your country. If your worker is covered by the Dutch system, Dutch rules apply: two years of continued wage payment during illness. With an A1 certificate, the rules of your country apply.
20. How do I prevent problems with Dutch authorities?
Ensure: timely notification, A1 certificates, correct employment contracts, payment of at least the Dutch minimum wage/CLA wage, good documentation, compliance with working hours and safety regulations, and engage legal expertise in case of doubt.
