1. What Are the Dutch Rent Increase Rules?

Landlords in the Netherlands can generally increase rent once every 12 months, but the maximum permitted increase depends on the type of rental home.

The government sets legal maximums for the annual increase. The rules are different for the social sector, middle-income sector and free sector.

For 2026, the maximum annual increases are:

The percentages above are maximum annual increases. A landlord may charge a lower increase or leave the rent unchanged.

2. Social, Middle-Income and Free-Sector Rentals

The first step in checking a rent increase is identifying which rental sector applies to your home.

For independent homes with rental contracts signed on or after January 1, 2026, the applicable rental sector depends on the home’s starting rent and its number of WWS points.

A home can fall within the middle-income sector if its starting rent is above €932.93 and no higher than €1,228.07, with the applicable points requirements. A home with 144 to 186 WWS points can also fall within the regulated middle-income sector when the applicable rules place it there, including certain cases where the starting rent is above €1,228.07.

For contracts signed on or after January 1, 2026, a self-contained home is generally in the free sector when its starting rent is above €1,228.07 and the home has 187 or more WWS points.

For older contracts, different rules can apply. The starting rent, the number of WWS points and the date on which the contract was concluded are important when determining the rental sector.

Social and middle-income homes are subject to maximum rents based on the Woningwaarderingsstelsel, commonly called the points system. Free-sector homes are not subject to a maximum rent under that points system.

3. Social Housing: Maximum Rent Increase in 2026

For most social rental homes, the maximum annual rent increase from July 1, 2026 is 4.1%.

For a self-contained social rental home with a current rent of €350 or more, the ordinary maximum increase is 4.1% if the income-based higher increase does not apply.

If the current rent is below €350 per month, the landlord can increase the rent by a maximum of €25 per month instead of applying the 4.1% percentage.

Higher-income social-housing tenants

Certain higher-income households in self-contained social housing can face an income-dependent increase instead of the ordinary percentage.

For the 2026 income-based increase, the relevant income is generally the household’s income from 2024, meaning two years before the rent increase.

The income-based increases apply to self-contained social rental homes. Different rules apply to rooms, caravans and caravan sites.

4. Middle-Income Rentals: Maximum Rent Increase in 2026

For self-contained middle-income rental homes, the maximum annual rent increase in 2026 is 6.1%.

The legal maximum is based on the increase in collectively agreed wages, known as cao-loonontwikkeling, plus one percentage point.

The relevant wage increase from December 2024 to December 2025 was 5.1%. Adding one percentage point results in the 2026 maximum of 6.1%.

The actual increase can be lower if the rental contract specifies a lower increase.

A middle-income rental home also has a maximum rent based on the points system. A rent increase cannot simply take the rent beyond the legally applicable maximum rent for the home.

If a tenant believes an annual increase is above the legal or contractual maximum, the tenant can ask the Huurcommissie to assess the increase within four months of the increase taking effect.

5. Free-Sector Rentals: Maximum Rent Increase in 2026

For free-sector rental homes, the maximum annual increase in 2026 is 4.4%.

The 2026 maximum is based on the lower of inflation or collectively agreed wage growth, plus one percentage point.

From December 2024 to December 2025, inflation was 3.4% and collectively agreed wage growth was 5.1%. The lower figure was therefore 3.4%, resulting in a legal maximum of 4.4%.

The 4.4% maximum applies to the annual rent increase of self-contained free-sector homes in 2026.

However, the landlord can only apply an annual contractual increase if the rental contract contains a provision allowing the annual rent increase.

If a contract specifies a lower percentage, the landlord must use the lower percentage.

If a contract contains a higher percentage, the landlord still cannot exceed the legal maximum of 4.4% in 2026.

The statutory cap on annual free-sector rent increases applies through May 1, 2029. The maximum percentage itself is determined separately for each year.

6. What Happens to Rent Increases in 2027?

The legal maximums for rent increases are determined year by year. As of September 21, 2026, the 2027 maximum annual increase for the middle-income and free sectors has not yet been announced.

The 2026 maximums therefore should not be presented as the final 2027 percentages for those sectors.

The social-housing maximum of 4.1% applies from July 1, 2026 until July 1, 2027. Higher-income social-housing tenants can fall under the separate €50 or €100 monthly increase rules described above.

For the middle-income sector, the annual maximum is linked to the relevant collectively agreed wage development plus one percentage point.

For the free sector, the annual maximum is linked to the lower of inflation or collectively agreed wage growth, plus one percentage point.

The relevant economic figures used for the calculation of a future year’s maximum therefore need to be known before that year’s percentage can be determined.

Tenants should check the latest government or Huurcommissie information when their 2027 rent increase becomes relevant.

7. Rent Increase Examples

Example 1: Free-sector rent of €1,500

Suppose your monthly rent is €1,500 and your 2026 contract allows the maximum increase.

A 4.4% increase would add €66 per month.

The new monthly rent would therefore be €1,566.

Example 2: Middle-income rent of €1,200

Suppose your monthly rent is €1,200 and the maximum 6.1% increase applies.

A 6.1% increase would add €73.20 per month.

The new monthly rent would be €1,273.20, provided the contractual and legal maximum-rent rules also allow that amount.

Example 3: Social rent of €800

Suppose your current social rent is €800 and you are subject to the ordinary 4.1% increase.

A 4.1% increase would add €32.80 per month.

The new rent would be €832.80, provided the rent does not exceed the maximum permitted rent for the home.

Example 4: Social rent below €350

If the current rent is below €350, the 2026 rule allows a maximum increase of €25 per month rather than the ordinary 4.1% calculation.

8. What Does Your Rental Contract Say?

Your rental contract is important because the legal maximum is not necessarily the amount you will actually pay.

In the free and middle-income sectors, the landlord can only apply an annual contractual rent increase when the contract contains a provision allowing it.

If your contract specifies a lower percentage than the legal maximum, the lower contractual percentage applies.

A contractual clause cannot override a legal maximum. For example, a free-sector contract cannot create a right to a 7% annual increase in 2026 when the legal maximum is 4.4%.

In the social sector, the landlord must provide a formal rent-increase proposal that follows the applicable rules.

9. How Often Can a Landlord Increase the Rent?

As a general rule, a landlord may increase the rent once every 12 months.

The increase usually follows the date specified in the rental agreement or, in the social sector, the annual statutory rent-increase cycle.

There are exceptions. For example, a rent increase can occur in the first year of a tenancy in certain circumstances, and a rent increase following a qualifying improvement to the property can be separate from the ordinary annual increase.

A landlord cannot simply raise the rent several times in the same 12-month period as ordinary annual rent increases.

10. Can Rent Rise More After Renovation?

A rent increase resulting from housing improvement is different from an ordinary annual rent increase.

In qualifying cases, a landlord may be allowed to increase the rent by more than the ordinary annual maximum because of improvements to the property.

The Huurcommissie distinguishes an increase after woningverbetering from the normal annual rent increase.

A tenant who believes an improvement-related rent increase is not justified can use the applicable Huurcommissie procedure.

The existence of renovation work does not automatically mean that every rent increase is allowed. The specific legal requirements and circumstances matter.

11. How Much Notice Must a Landlord Give?

For social housing, rooms, caravans and caravan sites, the landlord must normally inform the tenant of the rent increase at least two months before the increase takes effect.

The proposal must be made in writing, including by email where the applicable rules allow it.

The proposal must include information such as:

• the current and proposed basic rent
• the amount or percentage of the increase
• the effective date
• information about how to object
• an income indication from the Tax Administration where an income-dependent increase is used

For free-sector homes, there is no single statutory annual announcement date. The rental contract determines when an annual contractual increase takes effect.

12. What Can You Do If the Increase Is Too High?

First, compare the proposed increase with both your rental contract and the maximum allowed for your rental sector.

Social housing

If a social-housing rent increase does not comply with the rules, a tenant can object to the landlord.

The objection should be submitted before the rent increase takes effect.

If the tenant objects before the increase takes effect and the landlord still wants to proceed, the landlord must ask the Huurcommissie to assess the proposed rent increase.

Middle-income rental

For middle-income homes, a tenant can challenge an annual increase that exceeds the legal or contractual maximum.

The Huurcommissie says a request concerning an annual increase must generally be submitted within four months of the effective date.

Free sector

If a free-sector landlord increases the rent by more than the legal maximum or by more than the percentage permitted under the contract, the tenant can ask the Huurcommissie to assess the increase.

For a 2026 increase, the Huurcommissie says the request must be submitted within four months after the increase takes effect.

13. What Does This Mean for Expats?

The same rent-increase rules generally apply to expats and other tenants according to the type of rental home and rental contract.

Being an expat does not by itself create a separate maximum rent-increase percentage.

The most important questions are:

• Which rental sector does your home belong to?
• When did your rental contract start?
• What does your contract say about annual rent increases?
• What maximum applies in the relevant year?

For expats renting in the Netherlands, understanding the difference between social housing, middle-income rental and free-sector housing is therefore important when checking a rent increase.

14. What About Huurtoeslag?

A rent increase and huurtoeslag are separate issues, but the amount of rent you pay can affect the calculation of your housing allowance.

The huurtoeslag rules also changed in 2026. For example, from 2026 there is no longer a general maximum rent threshold for eligibility, although the calculation still uses a maximum rent amount.

This means a rent increase does not automatically mean that you lose huurtoeslag.

However, your personal entitlement depends on the rules for the relevant year, including your income, assets, household situation and housing circumstances.

Tenants receiving huurtoeslag should therefore check their individual situation with the Dutch Tax Administration rather than assuming that a rent increase will automatically increase or reduce the allowance.

No separate percentage applies simply because a tenant is an expat. The applicable rules depend on the rental sector, contract and year of the increase.

Can my rent increase affect my huurtoeslag?

It can affect the calculation of housing allowance, but a rent increase does not automatically mean that you lose huurtoeslag. Eligibility depends on the rules and your individual circumstances.
