Your water authority tax assessment will come later

You will receive your water authority tax assessment later than usual. Read on to find out what this means for you.

We have been upgrading our IT infrastructure for water authority tax. We also renewed My Waternet. This causes a delay in sending out the assessments. That is why you will receive the water tax assessment later than usual.

Assessment 2023

  • The 2023 assessment will be sent after the 2022 assessment.

Assessment 2022

  • We have started with sending out the 2022 assessments.

Assessment 2021

  • Not all assessments for 2021 have been sent yet. Therefore, you can still receive a 2021 assessment. You will receive the assessment for 2021 before the assessment of 2022 and 2023.

Pay in instalments

Do you not want to pay the whole assessment in one time? Then choose to pay in a maximum of 8 instalments via direct debit. You can change the number of instalments online in My Waternet.

Do you pay your assessment in 8 instalments? Your first instalment will be debited from your bank account in the first month after the assessment date. We will try to make sure that you will not pay multiple instalments for water authority tax in the same month. When sending your 2022 and 2023 assessment we will try to take this into account.
