Number of direct debit installments

The number of installments we collect depends on the amount of your assessment and when you request the direct debit.

Here's how it works

If you request the direct debit within three weeks of receiving the assessment, we will debit the assessment amount from your account in up to ten monthly installments. If the amount is less than €10 each time, we will debit the total amount in fewer installments.

If you request the direct debit later, there will be fewer months left to debit the amounts. The monthly amount will then be higher.

For example:

You will receive a water tax assessment of €161.68 at the end of January. You request direct debit within three weeks. We will then debit the first installment in February and the last installment in November. This makes a total of ten monthly instalments.

If you request the direct debit a month later (March in this example), we will debit the first installment in March. The last in November. This makes a total of 9 instalments. In this case, the monthly amount is slightly higher, because we divide the assessment amount over nine installments instead of ten. 

If you apply for direct debit soon after you receive your assessment, you can be sure that you will pay your water taxes in up to ten monthly installments.

Can I pay the assessment with iDEAL if I have a direct debit payment plan?

Yes. As soon as we have received and processed your payment via iDEAL, deductions via direct debit will stop for this assessment. However, the authorization remains valid. Thus, we will again collect future assessments in installments.

I sold my property, but you are still debiting money from my account.

If you sell your home during the year, it does not affect the assessment amount. The situation on January 1 is decisive for the entire year. So this year you will pay for the property you owned on January 1.

However, the notary usually settles the assessment amount with the buyer. The buyer pays a proportional part. You can find this on the settlement invoice you receive upon transfer. You then pay the total assessment amount to us.

If you use direct debit, monthly debits usually continue into the next year. This is because we do not impose the assessment until during the year and we want to give you time to pay the amount.

If you no longer wish to use direct debit, you must withdraw your authorization for this. You can easily arrange this through myhhnk.nl. You will then need to transfer the remaining amount at once.
