Understanding why your WOZ value may not match current housing prices
Your home's WOZ value affects property taxes and subsidies, yet it often differs from current market prices. This discrepancy stems from fixed valuation methods, not errors. Here’s what you need to know about how it’s calculated and why it matters.
| Key Fact | Details |
|---|---|
| Reference Date | WOZ value is based on January 1 of the previous year. |
| Valuation Method | Uses property data and comparable home sales, not current market trends. |
| Oversight | Monitored by the Valuation Chamber, an independent supervisory body. |
| Purpose | Determines property taxes, subsidies, and municipal funding. |
| Issuing Authority | SVHW (Dutch Valuation of Immovable Property Agency). |
The SVHW (Dutch Valuation of Immovable Property Agency) is responsible for determining the WOZ value of properties in the Netherlands. This value is crucial for calculating property taxes, determining eligibility for subsidies, and allocating municipal budgets.

Why doesn't the WOZ value align with the housing market?
Many people compare their WOZ value with media reports, CBS statistics, their neighbours' selling prices, or the current housing market. This can make it seem as though the WOZ value is incorrect.
Often, this is because the WOZ value is determined differently than people expect. Below are three reasons:
The WOZ value is based on a fixed reference date
The WOZ value is determined based on a fixed reference date: January 1 of the previous year. SVHW does not consider today's value or current housing prices. Since the housing market can change rapidly, the WOZ value may differ from what you see in your neighbourhood or hear in the news.
The WOZ value is a calculated and verified market value
The WOZ value is not an estimate based on gut feeling, but a calculated market value. SVHW uses data about your property and selling prices of comparable homes in your area. Using valuation models, it calculates the most accurate possible value. While it remains an estimate of the market value on the reference date, it is based on facts, market data, and checks.
SVHW follows fixed rules and is subject to oversight
When determining the WOZ value, SVHW adheres to national legal rules and fixed procedures. Additionally, SVHW itself verifies the quality of the valuations. The Valuation Chamber, an independent supervisory body, also monitors the work. This organisation assesses whether municipalities determine WOZ values carefully and in accordance with the rules. Only when quality requirements are met may SVHW publish the WOZ values.
In short: Your WOZ value is not an arbitrary number.
There is a meticulous process behind it, involving data collection, calculation, verification, and independent oversight. This ensures you can trust that your WOZ value is determined fairly and accurately.
