How to Apply for the 30% Ruling: 2026 Step-by-Step Guide

Who actually files the application

One of the most common misconceptions is that the employee applies for the 30% ruling. They don't. The application is a joint request by employer and employee to the Belastingdienst, signed by both parties on the same form. The employer's HR or payroll department is your real counterparty. They file it, they sign Section 5, and they're the ones who will actually apply the 30% deduction on your payslips once it's approved.

That has two practical consequences. First, the employee can't push this through alone. If your Dutch employer is slow or unfamiliar with the process, the application stalls regardless of how organised you are. Second, when something goes wrong (a question from the Belastingdienst, a request for clarification), both parties get involved. Plan your communication accordingly.

Before you apply: confirm you qualify

The application process is short. The eligibility homework is where most mistakes start. Run through these four checks before you spend an hour on paperwork.

1. The 150 km rule

You must have lived more than 150 km from the Dutch border for at least 16 of the 24 months before your first working day in the Netherlands. This rule trips up people from Belgium, Luxembourg, parts of Germany, and northern France. Large chunks of those countries are inside the 150 km zone. Short visits to the Netherlands during that 24-month window (conferences, holidays, brief work trips) don't break the rule, but they do have to be declared on the form. See our deep dive on prior visits to the Netherlands if you've been here before.

2. Recruited from abroad

You must have been hired from abroad, meaning your Dutch employer brought you in, not that you moved to the Netherlands on your own and then started job hunting. The Belastingdienst has tightened scrutiny on this criterion since 2025: roughly one in five applications now gets follow-up questions on recruitment evidence. Useful proof includes the dated job offer, written correspondence showing the employer initiated contact, and a contract signed before you arrived in the Netherlands.

3. The salary threshold

The 2026 minimum taxable salary (the salary after the 30% deduction) is €48,013 for the standard category and €36,497 for under-30 applicants with a recognised Master's degree. The corresponding gross figures are approximately €68,590 and €52,139 respectively. The threshold trips most applicants up because the math runs on the post-deduction wage, not the gross. If you're anywhere near the line, read our breakdown of salary threshold edge cases before filing.

4. Specific expertise

Salary above the threshold is treated as evidence of specific expertise, which is the formal eligibility criterion. There's no separate degree or skill test for the standard route; meeting the salary threshold is the test. The under-30 Master's route is the exception, and it requires the diploma to be recognised in the Netherlands (NUFFIC equivalence statement if the institution is non-EU).

If you want a quick verdict on your own situation, the live salary calculator on the homepage runs the threshold check and shows your monthly tax saving in one screen. The full eligibility checklist covers the edge cases.

Step 1: Gather the documents

Belastingdienst caseworkers reject incomplete files faster than they reject borderline ones. Assembling the package once, properly, is the single most useful thing you can do. The checklist:

• Signed employment contract. Both employer and employee signatures, with the start date that matches what you'll declare on the form. Offer letters don't substitute for a contract.
• CV with continuous employment history. No unexplained gaps. If you took a year out, say what you did and where you lived.
• Educational diplomas. Originals are fine in Dutch, English, French or German. For diplomas in any other language, attach a sworn translation. Under-30 Master's applicants need to include the NUFFIC equivalence statement if the degree is from outside the EU/EEA.
• Proof of residence abroad. Utility bills, bank statements, rental contracts, or a registration certificate from the local authority. Anything that places you at a foreign address during the 24 months before your first Dutch working day works. Two or three documents per address is usually enough.
• Employer's loonheffingennummer. The Dutch payroll tax number. Your HR department has this. It goes on the form itself.
• BSN. Your Dutch tax ID. If you haven't received it yet (it's issued at municipal registration), the application can still be submitted; the Belastingdienst will ask for it later.
• Passport copy. The page with your photo and personal details.

Step 2: Complete the joint application form

The official form is "Verzoek loonheffingen 30%-regeling" (request for 30% ruling, payroll tax). It has five sections, and the logic between them matters more than the individual answers.

• Section 1, past rulings. Did the employee previously hold a 30% ruling in the Netherlands? A "yes" here means different rules apply and any remaining months from the prior ruling carry over (they don't reset to 60).
• Section 2, residency at hiring. Was the employee living in the Netherlands when hired? For a standard application this is "No"; if "Yes," only narrow exceptions (PhD candidates, returning employees) keep the application viable.
• Section 3, salary and category. Standard route or under-30 Master's route. The salary figure goes here, and it must reconcile exactly with the contract.
• Section 4, prior NL presence. Every previous stay in the Netherlands over the past 25 years has to be listed, even short ones. Forgetting a 2018 conference is one of the easiest ways to invite extra scrutiny.
• Section 5, employer statement. Signed by an authorised representative of the employer. Without this signature, the form is incomplete.

Our application process page walks through how we typically handle this on behalf of clients, including the joint review with the employer before anything is signed. That joint review catches most form-logic mistakes.

Step 3: Submit within 4 months

Mail the completed form and supporting documents to: Belastingdienst / Kennis- en Expertisecentrum Buitenland, Postbus 2865, 6401 DJ Heerlen. There's no online portal for this application. Paper submission is the standard route.

The 4-month rule says this: if the application reaches the Belastingdienst within four months of your first Dutch working day, the ruling (once approved) applies retroactively from that first working day. If it arrives later, the ruling starts on the first day of the month after submission, going forward only. So a January 15 start date means a May 15 deadline for full retroactivity.

Step 4: Wait for the Belastingdienst decision

Standard processing time is currently 8 to 12 weeks. Applications filed in January–March (peak season) sometimes take longer because the volume is highest after employers' January hiring waves. Files with foreign-language diplomas or non-standard recruitment evidence routinely take the full 12 weeks while caseworkers verify the supporting documents.

Three things can happen:

• Approval (beschikking). You receive a written decision stating the start and end dates of the ruling, the percentage (30% through 2026, dropping to 27% for applications from 2027), and any conditions. Forward it immediately to your employer's payroll team.
• Request for information. The Belastingdienst asks for a missing document, a clarification, or additional recruitment evidence. Respond within the stated deadline (usually 4 weeks). The application doesn't get rejected, but the clock pauses.
• Rejection (afwijzing). Less common, but it happens, usually for failed eligibility on a substantive ground. You have 6 weeks from the decision date to file a formal objection (bezwaar). After that the door closes.

Step 5: After approval (payroll, duration, 2027)

Once the decision arrives, the practical work shifts to payroll. Your employer adjusts your gross-to-net calculation so 30% of your eligible salary is paid as a tax-free reimbursement of "extraterritorial costs." The next payslip should show the new split; if it doesn't, ask HR for confirmation that the decision has been logged in the payroll system.

The ruling runs for a maximum of 60 months measured from your first working day, not from the approval date. Any prior 30% ruling you've held shortens that. The duration doesn't reset. Some other practical points:

• The 27% phase-down. Applications dated from 1 January 2027 get a 27% exemption instead of 30%. Existing rulings approved before that date keep the full 30% for the remainder of their term. See the dedicated post on the 2027 changes for the lock-in mechanics.
• Partial non-resident status is gone. The Box 3 advantage that used to come with the 30% ruling was abolished in 2025. See our Box 3 impact piece for the new state of play on foreign savings and investments.
• Switching employers. The ruling doesn't follow you automatically. You and your new employer have to file a fresh application within 3 months of starting the new job. The remaining months of your original ruling carry over. See changing employers and your 30% ruling.
• Annual salary check. Every January, the Belastingdienst re-checks that your wage still clears the threshold for the current year. A pay cut or a long unpaid leave can end the ruling mid-term.

Common reasons applications get rejected (or delayed)

Five problems account for the bulk of rejections and information requests. None of them are unavoidable.

1. Salary below the threshold (usually a math error)

Applicants run the 30% threshold against gross salary instead of taxable salary. A gross of €68,000 looks comfortably over the €48,013 line, until you realise the threshold applies to the 70% portion that's actually taxable. Always check the math after the deduction.

2. Recruitment from abroad not adequately evidenced

If the dated chain of contact between the employer and a candidate located abroad is missing, the Belastingdienst can challenge the "recruited from abroad" criterion. Save the original job posting, the first outreach email, the dated offer letter, and the signed contract, all with timestamps before the employee's arrival in the Netherlands.

3. 150 km rule miscalculated

Some applicants assume the 150 km is measured from Amsterdam; it's actually the Dutch border. People from Brussels, Antwerp, Luxembourg City, much of North Rhine-Westphalia and parts of northern France think they qualify and don't. Use a reliable map measurement, and document any moves during the 24-month window.

4. Late submission

Not a rejection per se, but every month past the 4-month deadline costs the employee a month of tax-free benefit. The mistake is treating the deadline as soft because the ruling itself is still available; the money lost is real.

5. Incomplete documentation

Missing CVs, unsigned employer statements, untranslated diplomas, gaps in residence proof. Each missing item triggers a request-for-information letter that pauses the file for 4–8 weeks. A pre-submission checklist (and a second pair of eyes) prevents almost all of this.
