To apply for the 30% ruling as a new employee, you and your Dutch employer submit a joint request to the Dutch Tax Administration (Belastingdienst), normally using the official form for the 30% ruling withholding tax statement. If the request is filed within four months of your first working day and approved, the ruling applies retroactively from that first day.
If the request is filed after the four-month window, the ruling generally takes effect only from the first day of the month following the month in which the request was submitted. Any months before that are taxed in full and cannot be recovered later.
Many newcomers assume that the employer handles the whole process, or that a highly skilled migrant residence permit automatically qualifies them. Neither assumption is safe. The ruling has its own conditions, separate from the IND, and the outcome depends on your personal history, your salary and the dates in your file.
Who files the request, and how to apply for the 30% ruling as a new employee?
The 30% ruling is a tax facility granted to the employment relationship, not to the employee alone. For this reason, the request must be signed by both the employer and the employee. The Belastingdienst does not accept a request filed by the employee without the employer’s participation.
The employer must also be registered as a withholding agent for Dutch wage tax. In practice, this means the employer runs a Dutch payroll. A foreign employer without Dutch payroll registration should resolve its registration before a request can succeed.
Before signing, it is advisable to check the three core conditions, as published by the Belastingdienst:
- Recruitment from abroad: you were hired from outside the Netherlands, or seconded to the Netherlands by a foreign group company.
- The 150 km condition: for more than 16 of the 24 months before your first working day in the Netherlands, you lived more than 150 kilometres from the Dutch border.
- Specific expertise: your expertise is scarce on the Dutch labour market, which is assessed primarily through a minimum taxable salary norm that the Belastingdienst updates each year.
The salary norm for the 30% ruling is not the same as the IND salary threshold for highly skilled migrant requirements. The IND threshold is €5.942 gross per month for applicants aged 30 and over and €4.357 for those under 30. Meeting the IND threshold does not automatically mean that your taxable salary, after deduction of the 30% allowance, meets the tax norm. Both should be checked separately.
Step-by-step application and required documents
The procedure is administrative, but each step depends on the previous one. The following sequence is the most reliable in practice.
- Agree on the ruling in your employment contract. State explicitly that the employer will apply the 30% ruling, and clarify whether your gross salary will be restructured into salary plus a tax-free allowance. This avoids later disputes about net pay.
- Register with your municipality and obtain a BSN. The request form requires your citizen service number (BSN). Without it, the request cannot be processed.
- Collect your supporting documents (see the list below).
- Complete the joint request form. Both parties fill in their sections, and both sign. Your employer’s wage tax number (loonheffingennummer) must be included.
- Submit the request to the Belastingdienst within four months of your first working day. Keep proof of the submission date.
- Wait for the decision (beschikking). Until approval, the employer generally should not apply the ruling in payroll, or should do so only with a clear correction arrangement.
- Give the decision to your payroll department. Once approved, the employer applies the ruling and, where applicable, corrects earlier months retroactively.
Documents usually requested
- A copy of your signed employment contract or secondment agreement
- A copy of your valid passport or identity document
- Proof of your residence abroad during the relevant 24 months, such as a foreign address registration, rental contract or utility bills
- Your BSN and the employer’s wage tax number
For Turkish nationals, a residence certificate from the Turkish population register (yerleşim yeri belgesi) is often useful evidence of residence. Where you lived in several countries, gather proof for every period. If you are still waiting for your entry visa, the MVV processing time may affect your start date, and therefore the moment the four-month period begins.
The 4-month deadline for retroactive effect
The four-month period is counted from your first working day in the Netherlands, not from the date of your contract signature or your arrival. A request submitted within this period, if approved, applies from the start of employment. A request submitted later applies only from the first day of the month after submission.
Consider an example. An employee starts work on 1 February. A request filed by 31 May, if approved, covers February onward. If the same request is filed on 10 June, the ruling generally applies only from 1 July, and February through June are taxed without the allowance.
Delays commonly arise for these reasons:
- The BSN registration appointment is scheduled weeks after arrival.
- HR waits for the employee to “settle in” before starting paperwork.
- The employee assumes the employer has filed, while the employer assumes the employee will initiate.
- Foreign residence evidence must be requested from authorities abroad.
Agree in writing, preferably during onboarding, who prepares the form and by which date. If you change employers while already using the ruling, a different rule applies: the new employment should generally begin within three months of the previous one ending, and a new joint request is still required.
Timeline: how long approval takes
The Belastingdienst does not guarantee a fixed decision period for 30% ruling requests. Processing times vary with workload, the completeness of the file and whether the tax inspector requests additional information. A complete file generally moves faster than one with gaps in the residence evidence.
During the waiting period, you are taxed as a regular employee unless your employer has agreed otherwise. Once the decision arrives, retroactive application is processed through payroll corrections. You may therefore see a larger net payment in the month the correction is applied.
If the Belastingdienst sends a request for further information, respond within the period stated in the letter. A missed deadline can lead to the request being treated as incomplete. Keep copies of everything you send, together with the dates.
Common mistakes that cause rejection
Most refusals result from factual or documentary problems rather than complex legal questions. The table below summarises the most frequent issues.
| Mistake | Consequence | What to check |
|---|---|---|
| Filing after four months | No retroactive effect | Exact first working day |
| Recent stay within 150 km of the Dutch border | Condition not met | Residence history over 24 months |
| Salary below the tax norm after the allowance | Expertise not demonstrated | Taxable salary calculation |
| Previous residence or work in the Netherlands | Refusal or reduced duration | Earlier Dutch stays and tax filings |
| Missing employer signature or wage tax number | Request incomplete | Both sections of the form |
Note: earlier stays in the Netherlands, including study or prior employment, are often overlooked. Such periods can reduce the maximum duration of the ruling or affect eligibility entirely, depending on their length and timing. If your work history spans Turkey and the Netherlands, it may also be worth reviewing how your Turkish work history is recorded for social security purposes.
What to do if your application is refused
A refusal by the Belastingdienst is a formal decision against which you may file an objection (bezwaar). Under Dutch administrative law, the objection period is generally six weeks from the date of the decision. The objection should explain why the facts or the legal assessment are incorrect and include any evidence that was missing.
Before filing, review the reasons in the decision carefully. A refusal based on missing documents can often be remedied with additional evidence. A refusal based on the 150 km condition or the salary norm usually requires a more detailed factual and legal argument. Practical guidance on the 30% ruling objection procedure can help structure this step.
If the objection is rejected, an appeal to the administrative court is generally possible. Keep in mind that the tax outcome does not affect your residence permit; however, salary changes made to accommodate the ruling may affect whether you continue to meet IND thresholds. If your employment later ends, the job search period for highly skilled migrants is up to 3 months with less than 2 years on the permit, and up to 6 months with 2 years or more.
Frequently Asked Questions
Can I apply for the 30% ruling without my employer?
No, the request must be submitted jointly by you and your employer.
- Both parties sign the official request form.
- The employer must be registered as a Dutch withholding agent.
- Confirm the arrangement in your contract before you start.
- Bilingual support is available for Turkish citizens in the Netherlands.
Does a kennismigrant permit guarantee the 30% ruling?
No, the IND permit and the tax ruling are assessed under separate conditions.
- The IND checks its own salary thresholds and recognised sponsor status.
- The Belastingdienst checks the 150 km condition and its own salary norm.
- Review the immigration and employment overlap where salary is close to either threshold.
What happens if I miss the four-month deadline?
The ruling can still be granted, but generally only from the month after you submit the request.
- Earlier months are taxed without the allowance.
- File as soon as possible to limit the loss.
- Document why the delay occurred in case questions arise.
Is the 30% ruling transferred when I change jobs?
It can continue, but the new employer and you must file a new joint request.
- The new job should generally start within three months of the previous one ending.
- The remaining duration continues; it does not restart.
- Check your residence position as well, including your WW unemployment benefit rights during any gap.
How long do I have to object to a refusal?
The objection period is generally six weeks from the date of the decision.
- Use the date printed on the decision, not the date you received it.
- Attach any missing evidence to the objection.
- Seek advice early if the refusal concerns the 150 km condition or salary norm.
Does the 30% ruling count toward Dutch naturalisation?
The ruling is a tax matter and does not itself affect naturalisation eligibility.
- Naturalisation depends on residence duration, permit type and integration.
- Lawful residence during the ruling period generally counts as residence.
- See the conditions for Dutch citizenship applications for details.
As a practical next step, confirm your first working day, assemble your residence evidence for the previous 24 months and agree with your employer on a filing date well inside the four-month window. Because each file differs, having your dates, salary structure and documents reviewed before submission is a sensible precaution.
