Rent increase Netherlands 2026: what your landlord can ask

Every spring, millions of tenants in the Netherlands receive the same letter: the annual rent increase notice. For most renters it is an unwelcome moment, but the law sets clear limits on what landlords may ask. In 2026, specific maximum percentages apply, and which one applies to you depends on the type of housing you rent.

This article explains which maximum applies in your situation, when you can file an objection, and what to do if your landlord asks more than the legal cap.

Which maximum applies to you in 2026?

There are three categories of rental housing:

1. Social-sector housing (regulated rentals) A property falls in the social sector if the rent is below the liberalisation threshold, which sits at roughly €880 per month in 2026 (adjusted annually). For these properties the legislator sets a strict maximum.

For 2026 the social-sector cap is 5.8%. This is based on inflation over the previous year plus a small surcharge for maintenance investment.

If your household income exceeds a defined middle-income limit, housing corporations may apply a higher increase, up to a maximum of €100 above last year's cap. This higher cap is intended to encourage households that can afford more to move to the free sector.

2. Free-sector housing A free-sector rental has a rent above the liberalisation threshold. Here the rule is CAO wage development plus 1%. For 2026 that comes out at roughly 7.7%.

3. Mid-rent segment Since the Wet betaalbare huur (Affordable Rent Act) took effect, many properties in the middle segment also fall under regulated rules. Read our overview of the Dutch rental contract checklist if you want to confirm which category your home falls in.

How and when must your landlord announce the increase?

Your landlord must send the rent increase notice in writing, at least two months before the new rent takes effect. If the increase starts on 1 July, you must receive the letter before 1 May at the latest.

The notice must contain:

• The new rent amount
• The percentage of the increase
• The effective date
• Instructions for how to file an objection

If any of these elements is missing, or if the notice arrives too late, the increase cannot take effect on the planned date.

When can you object to a rent increase?

You can file an objection if:

• The percentage exceeds the statutory maximum
• The two-month notice period was not respected
• The notification letter contains errors
• You rent in the social sector and your landlord applies the middle-income surcharge while your income does not justify it

File the objection in writing with your landlord. Send it by registered post so that you have proof of delivery. If the landlord does not respond or rejects your objection, you can escalate to the Huurcommissie (Rent Tribunal, for social-sector rentals) or the local court (for free-sector rentals).

Also check first if your rent is already too high under the housing points system. Many tenants pay above the legal maximum even before any annual increase is applied. The new pillar guide tenant rights in Amsterdam walks through every step, and our renting a room in Amsterdam pillar shows the wider housing-search context.

What if your landlord asks more than the maximum?

You do not have to accept it. Pay the legal maximum and inform your landlord in writing why you are paying that amount. Keep every piece of correspondence.

If the landlord keeps insisting on the higher amount, you can escalate to the Huurcommissie (social housing) or start a court case (free sector). In practice most landlords back down once they realise the tenant is aware of the rules.

What about temporary rental contracts?

If you have a fixed-term contract that ends after a defined period, different rules apply. Temporary contracts may not be raised mid-term unless this is explicitly stated. Read our piece on temporary vs permanent rental contracts for more.

How to calculate your own maximum

If you want to confirm whether the proposed new rent is reasonable:

1. Find your current monthly rent (base rent, not including service charges)
2. Multiply by 1.058 (social) or 1.077 (free sector) for the 2026 cap
3. Compare with the proposed new rent on the letter

Anything above that figure is grounds for an objection.

For the wider picture on what your landlord can and cannot do, the new pillar guide tenant rights in Amsterdam, a complete guide covers maintenance, deposits, contract types, and the Huurcommissie procedure in one place. Pair that with Huismaatje to find a fairer next room when the current one stops being a fair deal.

Frequently asked questions

May my landlord raise the rent twice a year?

No. Dutch law allows only one rent increase per calendar year, on a fixed annual reference date. Two increases in the same year are not permitted, even if one is small.

Does the maximum also apply to a free-sector apartment?

Yes. The free sector has its own statutory maximum (CAO wage development plus 1%). Landlords cannot raise the rent without limits, contrary to a common misconception.

What if my landlord says he does not have to respect a maximum?

That is incorrect. Statutory maxima apply to all landlords in the Netherlands. Contact the Juridisch Loket or Woonbond if your landlord insists otherwise, both offer free advice.

Can I roll back a rent increase that has already taken effect?

If you object within the statutory window and the landlord applied the increase incorrectly, the Huurcommissie can roll it back and order the landlord to refund the difference. Act quickly, ideally within four months of the first increased payment.

Are there tenants who cannot be subjected to a rent increase at all?

Tenants whose home has serious defects that the landlord refuses to repair can request a rent freeze or even a rent reduction via the Huurcommissie. Document defects with photos and dated emails to the landlord.
