Why did I receive a tax assessment for multiple years?

Did you receive multiple bills for water authority tax? That can happen. Some of the assessments of previous years will only be sent this year. Sometimes at the same time as this year’s assessment.

Why do I get my assessment of previous years only now?

It took time for us to gather all the necessary data to make the correct assessments. That is why we're behind schedule. We're sorry for any inconvenience this may cause.

Did we deduct multiple amounts from your bank account?

Did you receive multiple water authority tax assessments? And did you choose to pay in instalments with direct debit? Then it's possible that we will deduct multiple amounts each month. For example, one of the amount may be an instalment for last year’s assessment. And the other amount may be an instalment for this year’s assessment.

Can't pay everything in one go?

You may choose to pay your water authority taxes in instalments.

  • Go to My Waternet and log in with your DigiD.
  • Adjust your payment method to 'pay in instalments or direct debit'
  • We will deduct the amounts near the end of the month, usually around the 28th.
