Every assessment notice from HHNK states the date by which you must have paid. That is the due date. If you do not pay the water board tax on time, HHNK will send you a reminder. 

Here's how it works

You will receive a reminder if you have not paid an assessment (in full) after the reminder. The reminder costs:

  • €8 for an assessment amount up to €454;
  • €18 for an assessment amount of €454 or more.

You must pay the outstanding amount including reminder costs within fourteen days of the date of the reminder. If you cannot pay this amount immediately, request a payment schedule by direct debit.
