The Regionale Belasting Groep aims to combine the different tax types into a single assessment notice wherever possible. This is done in an effort to save costs and to improve transparency for the client.
The Regionale Belasting Groep sends the notice to the same person who received it in the previous year. If no levy was imposed in the previous year, then the Regionale Belasting Groep will send the notice to the person who has been registered in the Municipal Personal Records Database (GBA) for the longest.
If you are also the owner of the home and your notices are combined into a single assessment notice, then the Regionale Belasting Groep will send the notice to the person who first registered with the land registry office.
If you live on your own, you are required to pay one pollution equivalent (1 pe). Households consisting of more than one individual must always pay three pollution equivalents (3 pe). This is a statutory regulation, which means you cannot contest it. The Regionale Belasting Groep bases its information on the number of persons registered at your address according to the data of the Municipal Personal Records Database (GBA).
We use the data registered in the Municipal Personal Records Database (GBA) to determine whether you should be charged one or three pollution equivalents.
If you live on your own, you should only be charged one pollution equivalent. If you start living on your own in the course of the year, we will automatically adjust the amount and you will be refunded or credited for any excess amount paid. You will receive the relevant notification from us. If you live alone but received an invoice for three pollution equivalents, then you may apply for a reduction. Please go to the first question for instructions on how to apply.
Always notify your local municipality of any changes to your personal data. Proper registration in the GBA prevents wrongful charges.
No, unfortunately not. The levy is based on the information contained in the Municipal Personal Records Database (GBA). Your data in the GBA do not change when you live at a different address temporarily, so the levy also remains unchanged.
Only if you move out of the water board area and/or if your family composition changes.
The amount of the water system levy will not change in the year of your relocation, as the levy is based on the situation on 1 January of that year. Even if you move, you still need to pay for the entire year. On the other hand, you will only be charged at your new address in the year following your change of address.
The water treatment levy will not change if you move to other accommodation within the region of the water board (unless the composition of your family changes, thereby possibly affecting the amount of the levy). You will not be invoiced for the current year at your new address. This will only happen in the year following your change of address.
If you move away from the region of the water board, the Regionale Belasting Groep will automatically adjust your water treatment levy and send you the relevant notification. You will also be refunded or credited for any excess amount paid.
Always inform your municipality of any address change. The municipality will then automatically forward the information to the Regionale Belasting Groep. There is one exception: if you move abroad, you must inform the Regionale Belasting Groep of this yourself and provide a correspondence address.
If your new address is still in the region of the water board, your change of address will have no effect on how much levy you need to pay. What you have overpaid at your previous address you will now underpay at your new address. So you will pay the correct amount on balance. This means you do not have to inform the Regionale Belasting Groep. You must however inform your municipality of the address change.
If you have moved out of the water board area, you may submit an appeal in writing. This should be accompanied by written proof of the date from which you no longer occupied the home (copy of termination of rental agreement or date of ownership transfer if you have sold your house). In this case too, you are still required to inform your municipality of the address change.
You are required to pay a water treatment levy/water system levy if you are the user (tenant or home owner) of self-contained accommodation.
The term ‘self-contained accommodation' refers to a situation where the occupants have access to their own facilities such as shower, toilet and kitchen. If you share one or more of these facilities with others, one of the following situations applies:
If item one or two of the above situations applies to you, and you have nonetheless received an invoice, please notify us of this. Please go to the first question for instructions on how to submit an objection.
Yes, in that case you are required to pay the invoice yourself. If your landlord has agreed to pay this charge, you need to arrange it with him. In the eyes of the law, you are subject to taxation.
No, the amount cannot be reduced. The Regionale Belasting Groep imposes the levy on the individual who is registered at that address on 1 January of that fiscal year according to the data of the Municipal Personal Records Database (GBA). It concerns a fixed fee per dwelling. So it makes no difference how many people live at that address.
You may only submit a letter of objection if you were not registered at the relevant address in the municipal personal records database on 1 January of that year. In that case, please go to the first question for instructions on how to submit an objection.

The amount will then be deducted from your account in a maximum of six instalments.

You may lodge an objection if you are the owner and if none of the above exceptions are applicable to you. Go to the first question for instructions on how to submit an objection.

The provisional assessment is an estimate based on the assessment of a preceding year. If you have not received an invoice for this address in the past, then the assessment will be based on your water use. The following rules apply to businesses with household wastewater (e.g. shops and offices):
Example of a company with household wastewater exceeding 218 m3 per year: 514 m3 water x 0.023 pe/m3 = 11,82 pollution equivalents.
Different rules apply to businesses with no household wastewater. If the Regionale Belasting Groep does not yet have any details on the water use, it will use an estimate of the number of pollution equivalents. If you do not agree with the amount you are being charged, you may lodge an objection. The first question explains how you can do this.
Greenhouse companies are charged three pollution equivalents per hectare (10,000 m2). The following rules apply:
For example: 36,000 m2 greenhouse area /10,000 x 3.0 pe = 10.80 pollution equivalents.
Go to the first question for instructions on how to submit an objection.
The following rules apply to businesses with household wastewater (e.g. shops and offices):

The water system levy for developed/undeveloped property is a tax for owners of developed/undeveloped properties. The tax is imposed on the person who is registered as owner in the land register on 1 January of that fiscal year.
The levy is based on the situation as per 1 January of the fiscal year and on the property registration data of the land registry office. If you have sold your property after this date, you will still be required to pay the full amount. When a property is sold, this levy is usually charged on to the new owner via a civil law notary. This is however an issue to be arranged between the buyer and seller.
The invoice is addressed to the person who is registered in the land register as the owner of the real rights (for example the owner, lessee or usufructuary) on 1 January of that fiscal year. How your name is displayed depends on how it is registered in the Municipal Personal Records Database (GBA). If there are any errors regarding your name, ask your local municipality to rectify them. If the invoice needs to be addressed to one of the business partners, this can be done in the following assessment. Please indicate this in writing by sending a letter to the Regionale Belasting Groep. You will find the address on your tax assessment.
This is only possible if the person whose name should appear on the invoice is also registered in the land register and has given the relevant permission (signature upon request).
In the event of a death, the beneficiaries are responsible for paying the invoice. In that case, the word ‘beneficiary' will be added. The name change will only take effect in records of the Regionale Belasting Groep once the change has been made in the land register. This will happen automatically.
If, in a divorce, the property is assigned to your ex-spouse, the updated data will automatically appear on the next invoice from the Regionale Belasting Groep once you have informed the land registry office of the change. The Regionale Belasting Groep will automatically receive the updated data from the land registry office.
No, unfortunately not. The Regionale Belasting Groep imposes the levy on the basis of the data from the land registry office, which registers the property of a general partnership (VOF) or a professional partnership under the private name of the relevant partners/participants of the partnership.
If the property was still in the hands of the pervious owner on 1 January of that fiscal year, then the invoice is still intended for that person. Please return the letter to us, with the reference: ‘no longer at this address'. If you know his/her current address, please provide it as well.
The municipality calculates the WOZ value on the basis of the Valuation of Immovable Property Act. For this the municipality will send you a WOZ assessment. If you do not agree with this value, you may lodge an objection with your municipality within six weeks of the WOZ assessment's invoice date. This means you should not approach the Regionale Belasting Groep if you want to contest the value.
The Regionale Belasting Groep will automatically adjust the value when the municipality reduces your WOZ value (in response to your objection). The assessment sum will then be reduced and you will be refunded or credited for any excess amount paid. You will receive the relevant notification automatically. This means that you do not need to submit a letter of objection with the Regionale Belasting Groep as well.
If you have received an invoice with an old value after already having received a confirmation of reduced value from the municipality, it means that the municipality has not yet notified the Regionale Belasting Groep of the reduced value. You will then need to:
Yes. From 2009, owners outside the dike area are also sent an assessment notice. New statutory rules were introduced in the beginning of 2009. A distinction is no longer made between the tasks of water management, water defence and clean water in waterways, lakes and pools and nature development.
As of 2009, water Boards have two tasks:
Because the general task of the water board is also relevant to the owners outside the dike area, they too are required to pay water system levies.
If you have a written question or comment, you may submit this via the inquiry form.
You may use the inquiry form to update your correspondence address for example.
The statutory period for the processing of letters of objection is six weeks after the deadline for submission of a letter of objection.

Remission is only possible for the water treatment levy for your home and the water system levy for residents.
Are your earnings at the income support level or lower? Then you may apply for remission. You must do so within two months of the date of the assessment notice. The fastest route is to fill out a digital form or fill in the remission section (application form) of the notice and return it (without enclosing any documents). The form has a barcode which facilitates the processing of your request. You will then receive a remission form from the Regionale Belasting Groep.
