30% Ruling Employer Cost Calculator Checklist for Dutch Payroll

What Qualifies a Person for the 30% Ruling?

The 30% ruling is available to foreign nationals hired by a Dutch employer to work in the Netherlands. The Tax Administration applies a salary norm test to ensure the ruling is not exploited for low-wage hires. In 2026, the salary norm is set at 46,660 euros per year (or 35,468 euros for employees under 30 with a qualifying master's degree). If your candidate's gross salary exceeds the norm, they almost certainly qualify.

Key conditions include: the person must be a foreign national (not a Dutch citizen), you must hire them specifically to work in the Netherlands, they must be a genuine specialist or skilled worker (the "knowledge worker" concept is broad and almost always met), and they must not have been a resident of the Netherlands for the two years before you hire them. This last condition is the most common disqualifier. If your candidate lived in Amsterdam for the past year, they do not qualify. If they are moving to the Netherlands from London for the first time, they do qualify.

The ruling runs for five years from the date it is approved by the Tax Administration. After five years, it can be extended or it expires, and the employee's salary reversion to full taxation is a mandatory conversation.

Salary Norms and Tax-Free Reimbursement Percentage

The salary norm is the first hurdle. For 2026, the minimum gross salary is set at 46,660 euros per year (or lower at 35,468 euros for applicants under 30 with a qualifying master's degree). These figures exclude the statutory holiday allowance but include all other compensation.

Once the norm is met, the ruling grants thirty percent of gross salary as a tax-free reimbursement. This is not a thirty percent tax deduction; it is a direct reimbursement by the Tax Administration. The employee's taxable salary for income tax purposes is reduced by the thirty percent reimbursement amount. This lower taxable base reduces their income tax withholding, pension deduction, and social security contributions, all calculated on the reduced amount rather than the full gross salary. For your employer payroll, the ruling changes the calculation only on the employee side. You still pay your statutory employer contributions on the full gross salary. The tax-free reimbursement is to the employee, not to you.

The Approval Process and Timeline

The 30% ruling is not automatic. You must file an application with the Tax Administration (Belastingdienst) within four months of the employee's start date so that the ruling backdates to day one of employment. This four-month window is the key to securing retroactive coverage from day one of employment. ICS Payroll handles the 30% ruling application as part of onboarding, so the filing can be made within this window. Filing within this window avoids the tax adjustments that would be required if coverage only started after approval.

The application process is straightforward: your payroll provider or tax advisor submits the application with the employee's details, contract, salary information, and proof of residence history. The Tax Administration reviews the salary norm, the foreign-national status, and the prior-residence condition. Approval typically arrives within four to eight weeks, but sometimes longer depending on the Belastingdienst's workload.

Once approved, the ruling runs for five years. The employee receives a ruling notification letter (the "30-regeling beschikking") from the Tax Administration, and your payroll provider includes the ruling in all future payroll calculations and wage-tax filings. The ruling is portable: if the employee stays in the Netherlands and works for another Dutch employer, the ruling can move with them (though the new employer must be aware and account for it).

Checklist: What Your Payroll Team Must Model Before Approval

Before you make a job offer conditional on the 30% ruling or commit to the hiring plan, your payroll team should model five scenarios:

• Salary norm check: Is the gross annual salary at or above 46,660 euros (or 35,468 for under-30s with a qualifying master's)? If yes, the candidate likely qualifies.
• Foreign-national status: Is the candidate a foreign national, not a Dutch citizen? Dutch citizens cannot use the ruling. Dual nationals are treated as Dutch citizens for ruling purposes if they hold Dutch nationality.
• Prior-residence history: Has the candidate lived outside the Netherlands for the two years before your hire date? If they lived in the Netherlands during that period, they do not qualify. If they are relocating from abroad for the first time, they qualify.
• Employer cost impact: What is the total monthly employer cost with and without the ruling? Does the ruling increase the employee's net pay enough to affect your salary budget?
• Filing timeline: Can your payroll provider file the application within four months of the start date? If you are hiring in November and the process is slow, can you make the four-month deadline (which would be early March)?

A single "no" on any of these questions may be disqualifying. If the salary is just below the norm, you could increase the offer. If the prior-residence condition fails, the ruling is not available. If your payroll provider cannot file within four months, you risk missing the retroactive approval window.

Pre-Approval Modelling: Employer and Employee Cost Scenario

The table above maps the key decision points. The critical insight is that the ruling does not increase your employer cost; it increases the employee's net pay through lower tax withholding. This makes the 30% ruling attractive both to you and to the candidate, since you both benefit without additional expense.

ICS Payroll's 30% Ruling Feasibility Process

ICS Payroll handles the 30% ruling application, the salary norm test, and the annual filings for qualifying expats. The firm's process is straightforward: send the candidate brief (name, hire date, gross salary, nationality, prior-residence history, education if under 30), and you get a feasibility memo back within one business day. The memo states whether the candidate qualifies, which salary norm applies, when the application must be filed, and what the estimated employer and employee cost impact is.

This one-business-day turnaround means you can make hiring decisions fast. You do not need to wait weeks for a tax advisor opinion; you can build the candidate's offer with confidence that the ruling numbers are accurate and the process is achievable.

Once the application is filed, ICS Payroll tracks the four-month deadline and manages the Belastingdienst communication. If the approval arrives and the candidate's ruling takes effect retroactively to day one, ICS Payroll adjusts the payroll records and, if needed, calculates any tax refund due to the employee from over-withholding in the months before approval.

Common Mistakes to Avoid

The three most common 30% ruling mistakes are: (one) missing the four-month filing deadline and losing retroactive coverage, (two) misclassifying a dual national (Dutch citizens do not qualify, even if they hold another nationality), and (three) hiring someone who lived in the Netherlands within the two years before the hire date. Each of these is easily avoidable if your payroll provider checks the conditions before you make the offer.

Another pitfall is assuming the ruling is approved once you file. The Tax Administration can request additional information, deny the application if the salary norm is not met or the foreign-national status is unclear, or slow-walk the approval past your four-month window. Your payroll provider should monitor the application and, if the four-month deadline is approaching without approval, escalate the case to the Belastingdienst or file a formal extension request.

Annual Compliance and Renewal

The 30% ruling is not a set-and-forget benefit. Each year, your payroll provider must confirm the ruling is still in effect, include it in all wage-tax filings and payslips, and watch for any changes in the employee's circumstances (such as promotion, salary increase, or relocation) that might affect the ruling's validity.

When the five-year ruling expires, you and the employee must decide: extend the ruling (possible for another five years if the salary and status conditions are still met), or allow it to lapse and move to standard taxation. Many employers choose to extend because the ruling is already approved and the process is simpler the second time. But if you do not extend, the employee's tax withholding changes, reducing their net pay, which can be a shock to the employee's budget and a reason to renegotiate salary. Note that as of 1 January 2027, the ruling percentage steps down from thirty percent to twenty-seven percent, so a renewal filed after that date will use the lower rate.

Your payroll team should also connect the 30% ruling to broader Dutch payroll compliance. The Dutch pension obligations for a foreign employer payroll provider checklist outlines mandatory pension schemes that apply regardless of ruling status; the 30% ruling affects only income tax and social security, not pension. The Dutch social security contributions checklist for foreign employers details which statutory contributions apply to your payroll. And for year-round planning, the annual 30% ruling compliance calendar for Dutch employers maps filing deadlines and renewal timelines so nothing slips through.

Getting Your Feasibility Memo and Next Steps

If you are considering hiring an international specialist and want to know whether the 30% ruling is available, send the candidate's brief to ICS Payroll: their name, gross monthly salary, citizenship, hire date, prior-residence history, and education level if under 30. You will get a feasibility memo back within one business day with the salary norm assessment, the estimated employer and employee cost impact, and the filing timeline. This memo is your go-ahead to make the job offer with confidence that the ruling numbers are solid and the Tax Administration process is on track.
