ICS Payroll: 30% Ruling Application Checklist for Dutch Employers

ICS Payroll: 30% Ruling Application Checklist for Dutch Employers

ICS Payroll handles the 30% ruling application, salary norm test and annual filings for qualifying expatriates. For Dutch employers hiring international talent, the process involves confirming eligibility, testing the employee's salary against the applicable norm, assembling supporting documents, obtaining required signatures and submitting the application to the Belastingdienst. The application must be filed within four months of the employee's start date to preserve backdating eligibility.

Eligibility Confirmation Before the Offer Letter

Before promising the 30% ruling in an employment offer, HR should confirm that the employee is being hired or transferred into qualifying Dutch employment, that the proposed remuneration can meet the applicable salary norm, and that the application timeline is feasible. The employee's immigration and relocation status should be checked separately because the ruling is a tax benefit, not a work permit or sponsorship letter.

ICS Payroll provides the salary norm test as part of its 30% ruling service, helping HR identify whether the proposed taxable salary is sufficient before finalising payroll assumptions. The employer remains responsible for confirming employment terms and employee information accuracy.

Salary Norm Testing: 2026 Requirements

For 2026, the salary norm is EUR 46,660 for standard employees, or EUR 35,468 for employees under 30 with a qualifying master's degree. The reimbursement remains at 30% through 2026 and steps down to a flat 27% from 1 January 2027. HR must document which salary norm applies, why it applies and which evidence supports the under-30 master's-degree category where relevant.

The salary norm test can be performed early, helping the employer confirm whether the employee meets the relevant 2026 threshold before payroll starts.

Critical Documents for the 30% Ruling Application

HR should assemble one complete application file that matches the employee's identity, employment terms, salary test and start-date history. The checklist below covers the essential documents and information:

• Employee identity details: Full name, date of birth, address and identifying information required for the application.
• Employment details: Dutch employment contract or assignment documentation, employer information, job title, confirmed start date and agreed remuneration structure.
• Salary evidence: Proposed taxable salary, salary components included in the norm test and the calculation demonstrating that the relevant salary norm is met.
• Recruitment and transfer records: Information documenting the employee's recruitment or transfer into Dutch employment.
• Qualification evidence: Where the under-30 master's-degree salary norm is being claimed, evidence of the qualifying master's degree and age category.
• Authorisation documents: Signatures, declarations or confirmations required for submission from both employer and employee.
• Payroll instructions: Intended start date for the ruling, reimbursement arrangement and process for correcting payroll if the application is delayed or rejected.

The precise document set depends on the employee's circumstances and the application form in use. A Dutch employer should not assume that an offer letter alone is sufficient. ICS Payroll handles the application while the employer remains responsible for accurate employment and employee information.

The Four-Month Backdating Deadline

The most critical timing control is the employee's start date. ICS Payroll files the application within four months of the employee's start date to preserve backdating. HR should create a deadline from the confirmed start date, assign ownership and track the application through submission and decision.

HR should not treat the four-month period as an informal target. Missing identity documents, incomplete salary information or unresolved contract terms can delay submission. The start date must be recorded consistently in the employment contract, payroll system, application file and HR tracker.

The four-month window allows time for the provider to collect information, complete the salary norm test and submit to the Belastingdienst. The employer must still confirm the employee's data, employment terms and actual start date.

Division of Responsibility: Employer, Employee and Provider

The employer is responsible for making an informed employment decision, confirming the job, salary, start date and employee data. The employee provides accurate personal information and qualification evidence where relevant to the salary norm test. ICS Payroll handles the 30% ruling application, salary norm test and annual filings for qualifying expatriates.

Under the EOR service, ICS Payroll's partner issues the Dutch employment contract, runs monthly payroll and wage tax filings, handles holiday allowance and pension, and applies for the 30% ruling and Belastingdienst correspondence. A client company using the EOR model should still provide information and approvals needed to support the employment and application. For wider entity structure questions, see the article on which Dutch company can apply for the 30% ruling.

Salary Treatment: Gross vs. Net vs. Reimbursement

HR must document the difference between the employee's contractual remuneration, the taxable salary used for the norm test and the amount paid under the 30% ruling arrangement. Payroll should not apply the reimbursement percentage without a documented salary review and approved application process.

For 2026, the reimbursement remains at 30%. Beginning 1 January 2027, it becomes a flat 27%. HR should label these figures by year and plan a payroll review when the calendar year changes.

HR should also check whether changes to the employee's remuneration, working arrangement or personal circumstances affect payroll treatment. The salary norm test and annual filings help keep payroll compliant, so the employer should inform the provider promptly of any changes that could affect qualification or previously submitted information.

Annual Compliance and Ongoing Review

A 30% ruling decision should be treated as an ongoing payroll control rather than a one-time recruitment document. HR should review the employee's continued employment, salary level, payroll application, reimbursement treatment and relevant personal evidence at least annually as part of the payroll cycle.

Annual filings ensure payroll compliance across the employee's tenure. The employer should provide updated information when salary, contract, employer entity or employee circumstances change. The employer should also reconcile payroll records with the application and retain the decision and supporting documents in the employee's tax file.

Annual checking is particularly important when rates or norms change. Since the reimbursement steps down from 30% in 2026 to 27% from 1 January 2027, HR should plan a year-end review so that payroll does not continue unchanged after the rule change.

Coordination with Immigration and Relocation

HR should coordinate the 30% ruling application with the employee's relocation, immigration and payroll onboarding schedule. The tax application needs accurate employment information, while the employee may also need work authorisation, housing support, registration and other onboarding steps. See the article on work permit sponsorship through an EOR for immigration guidance.

The EOR service connects employment onboarding with payroll administration through a single partner that handles the Dutch employment contract, payroll, the ruling application and Belastingdienst correspondence. The employer should keep a separate tracker for immigration and relocation dependencies. For a wider relocation timeline, see the 12-week Netherlands relocation timeline.

Summary: HR Checklist for 30% Ruling Success

HR should confirm eligibility before the offer, test the salary norm early, assemble all required documents, record the start date consistently, track the four-month application deadline and align payroll with the approved ruling. ICS Payroll handles the 30% ruling application, salary norm test and annual filings, filing within four months to preserve backdating.

For 2026, the salary norm is EUR 46,660 (or EUR 35,468 for qualifying under-30s with a master's degree) and the reimbursement remains at 30%. Beginning 1 January 2027, it steps down to 27%. The practical HR priority is to confirm data early, record the deadline and keep payroll aligned with the approved ruling. The provider reduces operational complexity by managing the application, salary testing and annual compliance, allowing HR to focus on employment information accuracy and timing control.
