How to Object to Your WOZ Value (Bezwaar) — Netherlands 2026

Every year, Dutch homeowners receive a WOZ-beschikking — an official letter stating the taxable value (WOZ-waarde) of their property. This number isn't just a formality. It directly affects how much you pay in:

• Onroerendezaakbelasting (OZB) — property tax charged by your municipality
• Eigenwoningforfait — the taxable benefit of owning your home (Box 1 income)
• Waterschapsbelasting — water authority levies

If your WOZ value is too high, you're overpaying. The good news? You can object. And if you do it right, you might get thousands of euros back — or save thousands over the next few years.

Here's how to file a WOZ bezwaar in 2026, what evidence you need, and what happens next.

What is the WOZ value (WOZ-waarde)?

The WOZ-waarde is the taxable value of your property as determined by your municipality. It's based on the market value of your home on a specific reference date (waardepeildatum) — usually January 1st of the previous year.

For example:

• WOZ-beschikking 2026 → based on market value as of January 1, 2025
• WOZ-beschikking 2025 → based on market value as of January 1, 2024

The municipality uses comparable sales in your area to estimate what your home would have sold for on that date. But municipalities don't always get it right. They use automated valuation models, which can miss property-specific issues like:

• Poor condition (dated kitchen, leaking roof, structural problems)
• Noise pollution (busy road, train tracks, airport flight path)
• Limited sunlight or unfavorable orientation
• Small or awkward layout
• Lack of parking or garden space

If any of these apply to your property, your WOZ value might be inflated.

Why does the WOZ value matter?

The WOZ value is the basis for three main charges:

Example:

• Your WOZ value is €400,000
• OZB: €400,000 × 0.10% = €400/year
• Eigenwoningforfait: €400,000 × ~0.50% = €2,000 added to Box 1 income → taxed at your marginal rate (~37%) = €740/year
• Waterschapsbelasting: €400,000 × 0.09% = €360/year

Total annual impact: ~€1,500/year

If your WOZ value is €50,000 too high, you're overpaying by roughly €190/year — or €950 over 5 years. That's real money.

When can you object to your WOZ value?

You have 6 weeks from the date of your WOZ-beschikking to file a bezwaar (objection).

Key dates for 2026:

• WOZ notices sent: February – early March 2026
• Objection deadline: typically mid-April 2026 (6 weeks from notice date)
• Reference date for 2026 WOZ: January 1, 2025

If you miss the 6-week deadline, you cannot object to that year's WOZ value. You'll have to wait until next year's notice.

Grounds for objection — when should you file a bezwaar?

You can only object if you believe your WOZ value is incorrect — meaning it doesn't reflect the true market value of your property on the reference date (January 1, 2025 for 2026 WOZ).

Valid grounds for objection:

1. Your WOZ value is higher than comparable properties in your neighborhood
2. Your property has specific defects or issues that lower its value (structural damage, noise, poor layout)
3. Recent sales data shows your WOZ value is inflated compared to actual transaction prices
4. The municipality used incorrect property details (wrong square footage, number of rooms, etc.)

Invalid grounds:

• "I think property taxes are too high" → That's a policy issue, not a valuation error
• "I can't afford to pay this much" → The WOZ value reflects market value, not ability to pay
• "My neighbor pays less" → Only relevant if their property is truly comparable

How to file a WOZ bezwaar — step by step

1. Gather evidence

Your objection needs to be backed by evidence. The stronger your case, the more likely you'll succeed.

What to include:

• Comparable sales — Find 3-5 recent sales of similar properties in your neighborhood. Use Funda, NVM Open Huizen Dag, or ask a local real estate agent.
• Professional appraisal — Hire a certified appraiser (taxateur) to value your home. This costs €300-€600, but it's the strongest evidence. Make sure they reference the January 1, 2025 valuation date.
• Property-specific issues — Photos, inspection reports, or contractor quotes documenting defects (roof damage, damp, outdated systems)
• Noise or environmental factors — Data from RIVM Geluidbelasting or flight path maps if you're near an airport

2. Write your objection letter

Your bezwaar must be in writing. You can submit it:

• Online via your municipality's website (usually through MijnOverheid.nl)
• By post to the address on your WOZ-beschikking
• In person at the gemeentehuis (town hall)

What to include in your letter:

• Your name, address, and WOZ identification number (from the beschikking)
• The date of the WOZ-beschikking
• A clear statement: "I object to the WOZ value of €[amount] because..."
• Your evidence: comparable sales, appraisal, property issues
• Your proposed WOZ value (optional but helpful)
• Your contact details

Example opening:

Geachte heer/mevrouw,

Hierbij maak ik bezwaar tegen de WOZ-beschikking met kenmerk [nummer] d.d. [datum]. De vastgestelde WOZ-waarde van €400.000 is naar mijn mening te hoog, omdat [recente verkopen van vergelijkbare woningen in mijn buurt tussen €350.000 en €370.000 lagen / mijn woning ernstige vochtproblemen heeft die de waarde verlagen].

Ik verzoek u de WOZ-waarde te herzien naar €360.000. Bijgaand treft u mijn onderbouwing aan.

(English translation: "I hereby object to the WOZ decision dated [date]. The assessed WOZ value of €400,000 is, in my opinion, too high because [recent sales of comparable homes in my area ranged from €350,000 to €370,000 / my property has severe moisture problems that reduce its value]. I request you revise the WOZ value to €360,000. Please find my supporting evidence attached.")

3. Submit your objection before the deadline

Online submission is fastest and gives you a digital receipt. If you send by post, use registered mail (aangetekend) so you have proof of delivery.

4. Wait for a response

The municipality has 8 weeks to respond to your bezwaar. They can:

• Accept your objection and lower your WOZ value
• Partially accept and lower it by less than you requested
• Reject your objection

If they don't respond within 8 weeks, you can assume they've rejected it and proceed to the next step.

What if your objection is rejected?

If the municipality rejects your bezwaar, you can appeal to an independent tribunal called the Waarderingskamer or the rechtbank (court).

Next steps:

1. Informal mediation — Some municipalities offer a free mediation session with a neutral expert. Worth trying before going to court.
2. Appeal to the Waarderingskamer — This is a specialized tribunal that handles WOZ disputes. Filing an appeal costs €0-€50 depending on your municipality.
3. Go to court — If the Waarderingskamer doesn't resolve it, you can appeal to the rechtbank. This is more formal and may require legal assistance.

Can you object to multiple years at once?

Yes. If you've been paying inflated property tax for several years, you can object to previous WOZ values — but only if:

• You're still within the 5-year statute of limitations
• You have new evidence (e.g., a recent appraisal that shows the value was wrong in prior years)

However, most people only object to the current year's WOZ value. Once it's lowered, future years' valuations are often adjusted accordingly.

What happens after your WOZ value is lowered?

If your objection succeeds, the municipality will:

1. Issue a revised WOZ-beschikking with the new (lower) value
2. Refund overpaid OZB and waterschapsbelasting for the current year
3. Adjust your eigenwoningforfait for your next income tax return — you'll pay less Box 1 tax

Example:

• Old WOZ value: €400,000
• New WOZ value: €360,000
• OZB refund: (€400k - €360k) × 0.10% = €40
• Waterschapsbelasting refund: (€400k - €360k) × 0.09% = €36
• Eigenwoningforfait savings: €40,000 × 0.50% = €200 less taxable income → **€74 tax savings**

Total savings: ~€150/year for as long as the lower WOZ value holds.

FAQ

How long does a WOZ bezwaar take? The municipality must respond within 8 weeks. If you appeal to the Waarderingskamer or rechtbank, it can take 6-12 months.

Do I have to pay while my objection is pending? Yes. You must continue paying OZB and waterschapsbelasting at the original WOZ value. If you win, you'll get a refund.

Can I object every year? Yes, but only if you have new evidence each year. If your property or the market hasn't changed, repeated objections are unlikely to succeed.

What if my WOZ value is too low? You don't have to object. The municipality might raise it in future years, but they won't retroactively increase it just because you didn't complain.

Can I use Funda listings as evidence? Asking prices aren't enough. You need actual sales prices (transactieprijzen). Use Kadaster or ask a real estate agent for recent sales data.
