Common legal mistakes expats make in the Netherlands, and the deadlines behind them

The legal mistakes expats make in the Netherlands are almost always deadline mistakes rather than knowledge mistakes. Registration in the Basisregistratie Personen must happen within five days of arrival if you are staying longer than four months. Basic health insurance must be arranged within four months. An objection to an immigration decision has to be lodged within the period stated on the decision itself, which is shorter than the general administrative period. And a challenge to a dismissal expires two months after the employment ends. None of these periods can be extended because you were still settling in.

The Dutch system is rules-based and largely automated, which makes it predictable but unforgiving. Most of the problems we see are not caused by a rule that is hard to find; they are caused by a rule that was found too late. What follows are the seven areas in which that happens most often, and what the law actually requires in each.

Not registering with the municipality in time

Anyone who intends to live in the Netherlands for longer than four months must register in the Basisregistratie Personen (Personal Records Database) at the municipality where they live, within five days of arrival. The old Gemeentelijke Basisadministratie was replaced by the BRP in 2014; the term still circulates online but is no longer the name of the register. On registration you are issued a burgerservicenummer (citizen service number), which is the key to virtually everything else.

Without a BSN you cannot be put on a Dutch payroll, cannot take out health insurance, cannot obtain DigiD and therefore cannot deal with any government body online, and will struggle to open a bank account. Registration also determines which municipality you belong to for waste charges, parking permits, school places and social services, and it is the address the tax authorities and the IND will use. A letter sent to a registered address is validly served whether or not you actually live there, which is why leaving an old registration in place is dangerous rather than convenient.

Registration is a personal obligation and is not discharged by your employer, your relocation agent or your landlord. It is also separate from your immigration status: holding a residence permit does not register you, and being registered does not give you a right of residence. If you are staying for less than four months you register instead as a non-resident, which still gives you a BSN.

Two practical points. Some landlords refuse to allow registration at their address, which is unlawful in most cases and should be resolved before you sign the lease, not afterwards. And if you move within the Netherlands or leave the country, you must report the change; failing to deregister on departure keeps you administratively resident, with consequences for tax and for benefits that can take years to unwind.

Treating the residence permit as a formality

Dutch immigration law works with sharply defined permit categories under the Vreemdelingenwet 2000, each with its own conditions, and an application is assessed against the category you chose, not against the category that would have suited you best. Applying under the wrong heading is not corrected by the Immigratie- en Naturalisatiedienst; it is refused. The main routes for internationals are the highly skilled migrant scheme, the single permit combining work and residence, study, family reunification, self-employment and the start-up route. Our guides on the highly skilled migrant scheme, the mvv and TEV procedure and the spouse visa set out what each requires.

The salary criteria for the highly skilled migrant scheme are fixed by the IND and published anew each year, with different levels by age and for recent graduates, so any figure quoted in an article is out of date within months. Check the current amount on the IND’s own page before you rely on it. The same applies to the income requirement for family reunification, which is tied to the statutory minimum wage and moves twice a year.

A permit is conditional and remains so. Losing the sponsoring employer, dropping below the salary norm, failing to make study progress or the ending of a relationship can each lead to withdrawal, and the holder has a duty to notify changes. Time spent in the Netherlands on a permit that is later withdrawn does not count towards permanent residence or naturalisation.

If a decision goes against you, the deadline is on the decision letter and it is short. One change matters here: since 15 April 2025 the IND no longer owes a penalty payment for deciding too late, so the pressure that provision used to create has gone. Where a decision is overdue, the remaining route runs through a formal notice of default and, if necessary, an appeal for failure to decide. Our Dutch immigration law guides collect the procedures by topic.

Signing the employment contract without reading the Dutch parts

Dutch employment law is largely mandatory: a clause that gives you less than the Burgerlijk Wetboek provides is simply void, and no amount of drafting changes that. The mistakes are therefore rarely about being trapped by an unfair clause. They are about not knowing which protections exist and letting them lapse.

Start with the probationary period. A contract for six months or less cannot contain one at all; for a fixed-term contract of less than two years the maximum is one month, and for a longer or open-ended contract two months. A probationary clause that exceeds the maximum is void in its entirety, which means there is no probation at all rather than a shortened one.

Then the chain of fixed-term contracts. Under the chain rule in article 7:668a of the Civil Code a succession of fixed-term contracts converts into an open-ended contract once you pass three contracts or three years, whichever comes first, with an interruption of more than six months breaking the chain. Legislation has been adopted to lengthen that interruption to three years, but it takes effect by royal decree and the six-month rule applies until it does. Our explanation of the chain rule sets out how the counting works.

Non-compete clauses deserve particular attention. In a fixed-term contract a non-compete clause is valid only if the employer sets out in writing, in the clause itself, the compelling business interests that make it necessary; without that written motivation it is void. In an open-ended contract it must be agreed in writing with an adult employee, and a court can still limit it in scope, area or duration, or award compensation for the period it restricts you. See our note on the non-compete clause and on the related non-solicitation clause.

On termination, three points are worth memorising. The employer’s notice period is at least twice the employee’s. An employer cannot simply dismiss you: it needs either your written agreement, a permit from the employee insurance agency for redundancy or long-term incapacity, or a court order on one of the statutory grounds. And a statutory transition payment is due from the first day of employment, including during probation. Where you disagree with a dismissal, the application to the court expires two months after the employment ended, and that is a forfeiture period, not a limitation period: it cannot be interrupted. Our guide to employee rights and our overview of employers’ rights and obligations deal with both sides.

One warning specific to internationals. A choice of foreign law in the contract does not remove the protection of Dutch mandatory employment rules if you habitually work in the Netherlands; European private international law preserves them. Conversely, a settlement agreement signed under pressure can cost you unemployment benefit if it is worded as a resignation. Have it checked before signing; the law gives you a statutory reflection period after signing a settlement agreement, and that period is longer where the employer failed to state it in the agreement.

Underestimating how much Dutch tenancy law changed in 2024

Rental law in the Netherlands is heavily regulated in favour of the tenant, and it was overhauled with effect from 1 July 2024. Two acts took effect on that date. The Wet vaste huurcontracten made the open-ended tenancy the norm again: a temporary contract for self-contained accommodation can now only be concluded in a limited list of situations, and a contract that does not fit one of them is an open-ended tenancy with full termination protection, whatever it says on the front page. The Wet betaalbare huur extended the statutory points system for rent setting into the middle segment and made it binding, so for a large part of the market the maximum lawful rent follows from the characteristics of the property rather than from what the parties agreed.

Alongside those, the Wet goed verhuurderschap, in force since 1 July 2023, imposes basic standards on landlords and letting agents: a written tenancy agreement, information in a language the tenant understands, a prohibition on discrimination and intimidation in the letting process, a ban on charging the tenant letting fees where the agent acts for the landlord, and a cap on the security deposit at twice the monthly basic rent, which must be repaid promptly after the tenancy ends. Municipalities enforce these rules and can impose administrative fines. Our article on the rental deposit, service charges and the Good Landlordship Act sets out what can and cannot be charged.

The mistake internationals make is accepting the rent as fixed. A tenant can ask the Huurcommissie to test the initial rent against the points system, but for that test there is a window running from the start of the tenancy, and it closes. Service charges can also be tested, and a landlord who cannot produce an annual statement of actual costs is in a weak position. Our guides on tenant rights in the Netherlands and on renovation and rent increases explain the procedures.

Two further traps. A diplomatic clause or a clause allowing the landlord to end the tenancy on short notice is usually ineffective against a tenant with statutory protection. And a room in a shared house may or may not be self-contained accommodation, which changes both the rent rules and the termination rules; check which regime applies before you sign.

Leaving health insurance and social security to chance

Almost everyone who lives or works in the Netherlands is legally required to take out Dutch basic health insurance, and to do so within four months of the obligation arising. Cover is backdated to the date the obligation started, so a delay produces a bill for the intervening premiums rather than a gap. If you remain uninsured, the CAK will first send warnings, then impose a fine, and ultimately enrol you with an insurer and collect the premium from your income.

Two groups are commonly caught out. Travel insurance and an employer’s international policy do not satisfy the obligation, however good the cover. And students, posted workers and people who continue to be socially insured in another EU member state may be exempt, but the exemption has to be established, usually with an A1 certificate or a decision from the Sociale Verzekeringsbank, rather than assumed. Getting this wrong in either direction is expensive: paying for insurance you were exempt from, or accruing an uninsured period you must now buy back.

Health insurance also interacts with your immigration status, because adequate insurance is a condition of several residence permits, and with your employment, because the employer’s contribution and the income-related contribution are handled through payroll.

Assuming your home country’s rules travel with you

This is the mistake with the longest tail, because it usually surfaces years later, in a divorce or an estate. Dutch private international law and the European regulations that apply here attach consequences to where you live, not to where you are from.

For inheritance, the European Succession Regulation makes the law of your habitual residence at the time of death the law that governs your estate, unless you have chosen the law of your nationality in a will or another declaration that satisfies the formal requirements. An international who dies while habitually resident in the Netherlands is therefore subject to Dutch succession law, including the statutory division in favour of a spouse and the compulsory portion for children, whatever the law of their home country would have provided. A will drawn up abroad may remain valid as to form and still produce an outcome the testator never intended.

For couples, the European regulation on matrimonial property regimes governs marriages concluded from 29 January 2019 and points, in the absence of a choice, to the law of the first common habitual residence after the marriage. Two people who marry abroad and then move to the Netherlands can find that Dutch matrimonial property law applies to everything they build up afterwards. A choice of law made before a notary removes the uncertainty; our article on the limited community of property explains the Dutch default, and our overview of the legal consequences of marriage or cohabitation with a partner from abroad covers the cross-border position.

Unmarried partners deserve a separate warning. Dutch law attaches no property or inheritance consequences to living together, however long it lasts, and there is no equivalent of the informal partnership status some legal systems recognise. Without a notarial cohabitation agreement and a will, a surviving partner inherits nothing and has no claim on the other’s assets.

Contracts follow the same logic. A choice of foreign law in a commercial contract is generally respected, but mandatory Dutch rules on employment, consumer protection, agency and tenancy continue to apply where the connecting factors point to the Netherlands, and a jurisdiction clause determines only which court hears the case, not which law it applies.

Tax: the one area to hand to a specialist immediately

We do not give tax advice, and that is a deliberate limit rather than a disclaimer. What internationals need to know at the legal level is short. If you are resident here for tax purposes, you are in principle taxable on your worldwide income and required to declare it, with double taxation relieved under the applicable treaty rather than by leaving income out of the return. Residence for tax purposes is decided on the facts, not on your permit or your registration, and it is possible to be treated as resident in two countries at once until a treaty tie-breaker resolves it.

The expat facility for incoming employees, under which part of the salary can be paid free of tax, has been amended repeatedly in recent years; the percentage, the salary norms and the maximum duration are set by legislation that has changed more than once and should be checked for the year in question. The same caution applies to the treatment of a foreign pension, of an owner-occupied home abroad, and of assets in box three, all of which have been the subject of legislative change.

Practically: engage a tax adviser before your first Dutch payroll rather than before your first tax return, keep the documentation of foreign income and assets, and do not rely on general information written for a previous year. Where a tax question overlaps with an employment, immigration or corporate issue, we work alongside your adviser rather than replacing them.

Missing the deadline: the costliest of the legal mistakes expats make in the Netherlands

If there is one thing to take from this article, it is that Dutch law runs on periods that expire without warning and that are, in most cases, incapable of being extended. A decision by a public authority becomes final if no objection is lodged in time, and the merits are then no longer examined at all. An application to the court about a dismissal expires two months after the employment ends. A challenge to the initial rent must be brought within the window that follows the start of the tenancy. A complaint about a defect in something you bought must be made within a reasonable time of discovering it, and for immovable property that means promptly and in writing.

Ordinary claims are subject to limitation periods that are longer but still finite, and they can be interrupted, which is one of the few places where a simple letter genuinely preserves a right. A written notice in which you unequivocally reserve your right to performance interrupts the limitation period and starts a new one. It costs nothing and it is routinely forgotten.

The practical rule is to treat every letter from a Dutch authority, employer or landlord as containing a deadline until you have established that it does not, and to have anything you do not understand read the same week rather than the same month. Almost every case we cannot help with is one where a period has already run.

How Law and More can help

Law and More advises internationals living and working in the Netherlands on the legal side of settling here: residence permits and objections against IND decisions, employment contracts, settlement agreements and dismissal, tenancy disputes and rent testing, cohabitation agreements, prenuptial conditions and wills, and the cross-border questions that arise when a life is spread over more than one country. We work in English and several other languages, and we say clearly where a question belongs with a tax adviser or a civil-law notary instead. Our practice guides are collected by subject, including our Dutch employment law guides and our Dutch family law guides. If you would like your situation reviewed before a deadline rather than after it, please contact Law & More.
