Introduction

The 30% ruling (also known as the expat ruling) is a tax advantage for employees who come to the Netherlands from abroad to work. A detailed explanation can be found here: https://exterus.nl/en/blogs/the-what-why-and-how-of-the-30-ruling-in-the-netherlands. For HR managers and expats, it is not only important to understand how the ruling works, but also how to calculate the amount.

1. What is the 30% ruling?

The ruling allows an employer to split the agreed salary into up to 70% taxable salary and up to 30% as a tax-free expat allowance.

Conditions (2025):

  • The employee must possess specific expertise that is scarce in the Dutch labor market. To qualify as specific expertise, the employee must meet the following income thresholds:

    • Age 30 and older: taxable salary must be at least €46,660 gross per year (excluding tax-free allowance).

    • Younger than 30 with a master’s degree: taxable salary must be at least €35,468 gross per year (excluding tax-free allowance).

  • Cap: The tax-free allowance is capped at €73,800 per year. For a salary of €246,000 or higher, the 30% is calculated over a maximum of €246,000.

  • The employee must continue to meet the specific expertise conditions for the entire duration of the ruling.

2. What is the 30% calculated on?

The 30% is calculated on taxable salary from current employment, including fixed taxable components (such as holiday allowance), but excluding:

  • Exempt allowances

  • Taxable bonuses from previous employment

  • Transition and severance payments*

  • Payments during gardening leave (non-active period)

A common mistake is forgetting that gross deductions, such as pension contributions, reduce the taxable salary and therefore must also be included in the calculation.

3. Step-by-step: How to calculate the amount

Step 1: Determine the gross salary for the 30% ruling

Example:

  • Annual salary: €70,000

  • Holiday allowance: €6,400

  • Company car addition: €10,000

  • Pension contribution: €3,000

  • Transition payment*: €3,000

Total gross salary: €83,400

* The transition payment is excluded, as it counts as salary from previous employment.

Step 2: Calculate 30%
30% of €83,400 = €25,020

Step 3: Check the cap
Since the gross salary in this example is lower than €246,000, the full amount applies.

Step 4: Check specific expertise
Since the taxable salary in this example is higher than €46,660 (or €35,468 if under 30 with a master’s degree), the full 30% tax-free allowance may be applied.

€83,400
− €25,020 = 58,380

Step 5: Apply in payroll administration
The amount of €25,020 is paid out tax-free; the remaining €58,380 is taxed under normal Dutch payroll tax rules.

4. Common Mistakes

  • Using net instead of gross salary in the calculation.

  • Failing to check annually whether the employee still meets the minimum requirements for specific expertise.

  • Forgetting to take gross deductions into account.

  • Not considering changes such as part-time work or sabbaticals.

  • Not anticipating that once the employee turns 30, the higher income threshold applies starting the following month.

  • Not adjusting the percentage of the tax-free allowance if the taxable salary falls below the minimum income threshold https://exterus.nl/en/blogs/can-you-lose-the-30-ruling

  • Forgetting to check the cap. Note: this also changes annually, and certain situations may fall under transitional rules.

5. Practical Tips for HR and Expats

  • Check annually whether the employee still meets the income thresholds and the cap.

  • Clearly communicate the impact on net income, especially when the cap or minimum thresholds are reached.
