Received a letter from your landlord announcing a rent increase? Before you accept it, you should know that Dutch law sets strict limits on how much your rent can go up each year. Many expats simply pay the new amount without checking whether the increase is actually legal. In this guide, I will explain exactly what your landlord is allowed to do, what they are not, and how to fight back if the increase is too high.
Having worked in the Dutch housing industry for years, I have seen landlords propose increases that exceeded the legal maximum more often than you might expect. Sometimes it is intentional, sometimes it is a genuine miscalculation. Either way, the result is the same: you end up paying more than you should. This guide gives you the knowledge to prevent that. If you are new to renting in the Netherlands, I recommend starting with our complete guide to tenant rights for the full picture.
Maximum Rent Increases in 2026
The Dutch government sets maximum rent increase percentages every year. For 2026, the limits depend on which rental category your home falls into.
For detailed information on rent increases and how to object, read our guide to rent increases in the Netherlands.
Social housing (sociale huur) has a maximum increase of 4.1 percent, effective from 1 July 2026. This applies to properties scoring up to 143 WWS points, with a maximum rent of €932.93 per month. There is one alternative: if your current rent is below €350 per month, your landlord may apply a fixed increase of €25 per month instead of the percentage, whichever is higher.
Mid-range rental (middenhuur) has a maximum increase of 6.1 percent, effective from 1 January 2026. This applies to properties scoring between 144 and 186 WWS points, with a maximum rent of €1,228.07 per month.
Free sector (vrije sector) has a maximum increase of 4.4 percent, effective from 1 January 2026. This applies to properties scoring 187 WWS points or more. In the free sector, the maximum is calculated as the lower of CPI inflation or CAO wage growth, plus one percentage point. For 2026, the CPI was 3.4 percent, so the maximum became 4.4 percent.
These are absolute maximums. Your landlord can increase by less, or not at all, but they can never exceed these percentages.

How the Rent Increase Process Works
Your landlord cannot simply raise the rent without following a specific legal process. Here is what the law requires.
Written notice is mandatory. Your landlord must send you a written proposal for the rent increase. This can be a physical letter or an email, depending on your contract. The proposal must clearly state the current rent, the proposed new rent, the percentage increase, the effective date, and your right to object.
Two months’ notice is required. Your landlord must send the proposal at least two months before the increase takes effect. For social housing, where increases typically take effect on 1 July, the notice must be sent by 30 April at the latest. If your landlord sends the notice too late, the increase cannot take effect on the proposed date.
Only one increase per year. Your landlord can only raise the rent once per twelve months. If your rent was increased in March 2026, the next increase cannot happen until March 2027 at the earliest.
The increase applies to the base rent only. The increase percentage applies to your kale huur (bare rent), not to service charges. Service charges have their own rules and must be accounted for separately.
What to Check When You Receive a Rent Increase
When you receive a rent increase proposal, do not just accept it. Take five minutes to check the following.
Is the increase within the legal maximum? Compare the proposed percentage to the maximums listed above. If your landlord proposes 5 percent for a social housing property, that exceeds the 4.1 percent maximum and is illegal.
Was the notice sent on time? Check the date of the letter and count back from the proposed effective date. If the landlord sent it less than two months before the increase date, the increase is not valid on the proposed date.
Has it been at least twelve months since the last increase? If your rent was raised less than twelve months ago, this new increase is not allowed.
Does the new rent exceed the legal maximum for your property? Even if the percentage is within limits, the resulting rent cannot exceed the maximum allowed for your home’s WWS points. For example, if your property scores 140 points and the maximum rent for that score is €900, your landlord cannot raise the rent above €900, regardless of the percentage.
Is the proposal correctly addressed and complete? The notice must include all the required information mentioned above. An incomplete notice is not valid.

Income-Dependent Rent Increases
For social housing and mid-range rentals, there is an additional type of increase based on your household income. This is called the inkomensafhankelijke huurverhoging.
If your household income is above certain thresholds, your landlord may apply an extra increase on top of the standard maximum. For 2026, the thresholds and additional amounts are as follows.
For single-person households with an income between €59,504 and €70,149 (or multi-person households between €68,858 and €93,531), the landlord may apply an additional fixed increase of €50 per month.
For single-person households with an income above €70,149 (or multi-person households above €93,531), the landlord may apply an additional fixed increase of €100 per month.
There are important exemptions. Households where someone has a disability or chronic illness are exempt from income-dependent increases. Income from children under 23 living at home does not count towards the threshold.
Your landlord must request your income data from the Belastingdienst (Tax Authority) to apply this increase. If they have not done this, they cannot apply an income-dependent increase.
How to Object to a Rent Increase
If you believe the proposed increase is too high or otherwise illegal, you have the right to object. Here is the step-by-step process.
Step 1: Do not pay the increased amount. Continue paying your current rent. By paying the higher amount, you may be seen as accepting the increase.
Step 2: Send a written objection to your landlord. Write a letter or email to your landlord explaining why you disagree with the increase. Be specific: state the legal maximum, point out any errors in the calculation, or explain why the notice was not valid. Keep a copy of everything.
Step 3: File a complaint with the Huurcommissie. If your landlord does not withdraw or adjust the increase, you can take it to the Huurcommissie (Rent Tribunal). The filing fee is €25, and you do not need a lawyer. The Huurcommissie will assess whether the increase is legal and issue a binding decision.
Important deadlines. For social housing and mid-range rentals, you have three months after the effective date of the increase to file with the Huurcommissie. For free sector rentals, you have six weeks after the effective date. Missing these deadlines means losing your right to challenge the increase through the Huurcommissie.

Service Charges: Different Rules
Service charges (servicekosten) are separate from your base rent and follow different rules. It is important to understand the distinction because some landlords try to shift costs from rent to service charges to get around rent controls.
Your service charges can include costs for shared utilities, building insurance, cleaning of common areas, elevator maintenance, and similar shared expenses. Your landlord must provide an annual itemised breakdown of these costs.
Unlike base rent increases, there are no fixed percentage caps on service charge increases. However, increases must be reasonable and based on actual costs. If you believe your service charges are too high or not properly accounted for, you can dispute them through the Huurcommissie.
An important change for 2026: service charges are no longer included in the calculation for huurtoeslag (housing allowance). Only your kale huur counts. This means that if you receive housing allowance, your benefit amount may be lower than before.
Rent Harmonisation: What Happens When a New Tenant Moves In
Rent harmonisation (huurharmonisatie) is the practice of adjusting the rent when a property gets a new tenant. This is separate from the annual increase and is worth understanding if you are about to sign a new lease.
When a previous tenant moves out, the landlord can set a new rent for the next tenant. However, this new rent cannot exceed the legal maximum based on the property’s WWS points. So even with rent harmonisation, the points system protects you.
This is why it is so important to check your WWS points when you move into a new property. Your landlord may have set the initial rent at or near the maximum, but if they calculated the points incorrectly, you could be overpaying from day one. Use the Huurprijscheck tool on the Huurcommissie website to verify this.
Since 2025, landlords are required to provide new tenants with a full breakdown of the property’s WWS points and the corresponding maximum rent before signing the contract. If your landlord did not provide this, that is a red flag.
Common Mistakes Expats Make with Rent Increases
From my experience in the Dutch housing market, these are the most common mistakes.
Accepting every increase without checking. Many expats assume the landlord’s calculation is correct and simply start paying the higher amount. Always verify the percentage against the legal maximum.
Not knowing which category their home falls into. The maximum increase differs significantly between social (4.1%), mid-range (6.1%), and free sector (4.4%). If you do not know your category, you cannot check the increase.
Missing the objection deadline. If you wait too long to object, you lose your right to challenge the increase through the Huurcommissie. Act quickly once you receive the notice.
Confusing service charges with rent. Some landlords increase service charges significantly while keeping the rent increase within limits. Check both amounts carefully and request a breakdown.
Paying the increased amount while objecting. If you start paying the new amount, it weakens your position. Continue paying the old rent while the dispute is being resolved.
Not keeping the rent increase letter. Always save the original notice. You will need it if you file a complaint with the Huurcommissie.
A Quick Checklist When You Receive a Rent Increase
- Check which rental category your home falls into (social, mid-range, or free sector)
- Verify the proposed percentage against the 2026 maximum (4.1%, 6.1%, or 4.4%)
- Confirm the notice was sent at least two months before the effective date
- Check that it has been at least twelve months since the last increase
- Verify the new rent does not exceed the maximum for your property’s WWS points
- If the increase is too high, send a written objection to your landlord
- If your landlord does not cooperate, file with the Huurcommissie within the deadline
Final Thoughts
A rent increase does not have to be a stressful event. In most cases, your landlord will propose an increase that is within the legal limits, and you can simply accept it. But when the increase is too high, Dutch law gives you clear and effective tools to push back.
The key is knowing your rights and acting quickly. Check the numbers, send a written objection if needed, and do not hesitate to involve the Huurcommissie. The system is designed to be accessible, even for expats who are new to the Netherlands.
