A letter from the Dutch Tax Authority about a 30% ruling audit can be a stressful experience for many expats. The 30% ruling is a valuable tax benefit that keeps up to 30% of your salary tax-free, but the Dutch tax authority regularly conducts audits to ensure that all conditions are properly complied with. However, with proper preparation and knowledge of the process, you can navigate through this audit with confidence.
In this article, we explain what an expat tax audit exactly entails, which documents you need, and how you can avoid common mistakes. We also discuss when it is wise to engage professional support for complex situations.
What triggers a 30% ruling audit?
The Tax Authority uses various criteria to determine which 30% ruling applications and ongoing rulings are audited. Inconsistencies in tax returns form one of the most common triggers for an audit.
Changes in your employment circumstances can also trigger an audit. Think of employer changes, salary modifications, or changes in your job description that may affect your eligibility for the ruling.
Additionally, the Tax Authority conducts random audits as part of their regular compliance activities. These selections are not necessarily based on suspicious activities, but serve as a sample to monitor general compliance.
Other factors that can trigger an audit are:
- Uncertainties about your residence in the 24 months preceding your Dutch job
- Questions about the scarce expertise you represent
- Discrepancies between the information in your application and other tax data
- Reports from employers about changes in employment contracts
Essential documents for your audit
Thorough documentation is crucial for a successful Tax Authority audit. Collecting all necessary papers before the audit begins saves time and demonstrates your professionalism.
| Document category | Specific documents | Important for |
|---|---|---|
| Employment contracts | Original contract, amendments, job descriptions | Proof of scarce expertise |
| Payroll administration | Pay slips, annual statements, bonus payments | Verification of salary levels |
| Residence history | Rental agreements, GBA extract, utility bills | 150km rule verification |
| Travel documentation | Passport stamps, flight tickets, hotel reservations | Proof of foreign recruitment |
Ensure that you organize all 30% ruling documents chronologically and make copies of original documents. Keep correspondence with your employer about the 30% ruling, including the written agreement in which both parties confirm that they understand the consequences of the ruling.
Additional documents that can be valuable:
- CV that clearly illustrates your education, work experience and expertise
- Work permit (if applicable)
- Proof of your BSN registration
- Bank statements that confirm your residence and financial situation
Common mistakes during an audit
Many expats make the same mistakes during 30% ruling preparation, which can lead to problems. Not fully understanding the 150-kilometer rule is a common pitfall. This rule requires that you lived more than 150 kilometers from the Dutch border for at least 16 of the 24 months preceding your first working day.
Another critical mistake is incomplete documentation. Expats often underestimate the importance of keeping all relevant papers from the moment of recruitment. Missing documents can lead to delays or even withdrawal of the ruling.
Incorrect interpretation of what “scarce expertise” means also causes problems. The Tax Authority assesses not only your salary level, but also whether your employer actually had difficulty finding comparable expertise locally.
Other common mistakes are:
- Insufficient preparation for specific questions from the auditor
- Not reporting employer changes within the allowed timeframes
- Unclear about the date of foreign recruitment
- Incorrect calculation of the maximum tax-free allowance
How does the audit process work exactly?
The expat tax Netherlands audit process usually begins with an official announcement by mail. The Tax Authority gives you a reasonable period to collect the requested documents, usually between 2-4 weeks.
After receiving your documentation, a thorough assessment follows. This phase can take 1-3 months, depending on the complexity of your situation. During this period, the Tax Authority may ask additional questions or request extra documents.
In some cases, a personal interview is scheduled. This happens especially in complex situations or when there are uncertainties about your eligibility. Prepare for questions about:
- Your recruitment process and why you were chosen
- Details about your residence history before arriving in the Netherlands
- Specifications of your expertise and how it is scarce in the Dutch market
- Changes in your employment circumstances since the grant
The final decision is communicated in writing. With a positive outcome, your ruling simply remains in effect. In case of problems, you get the opportunity to object to the decision within six weeks.

- You have had international transfers within a multinational
- The Tax Authority asks specific questions about your expertise or recruitment process
