What information can you find in your assessment?
Every assessment is different. The information it includes, depends on your specific situation. Below we explain the different types of tax in further detail.
- Water system charge for buildings: You are the owner of 1 or more properties. We calculate this amount based on the WOZ value (value of immovable property) of your house. The assessment will explain how we have calculated this.
- Water system charge for residents: This is a fixed amount per year per household. Even if you move during the year, you pay for the whole year. We take into account the address where you resided on 1 January.
- Water treatment charge for residents: Each household pays for 3 pollution units. Except if you live by yourself, then you pay for 1 pollution unit. Children under the age of 18 also count as residents. You pay a water treatment charge only for the period of the year you are the owner or user of a property. In the event you move house, we will lower this part of the assessment.
- Pollution charge: Is your property not connected to the public sewer system? Then you must pay a pollution charge. We calculate these costs in the same way as the water treatment charge.
Exactly how much you pay depends on your situation.
