A Dutch tax payment is simple, except for one field that quietly decides whether your money actually counts: the betalingskenmerk. Skip it, and you can pay the right amount to the right account and still get chased for a fine. Here is what this code is and how to pay the Belastingdienst correctly.
What the betalingskenmerk is
The betalingskenmerk is the payment reference for a tax bill: a 16-digit code that tells the Belastingdienst which aanslag (assessment) your payment belongs to. As the Belastingdienst explains when you’ve lost your payment details, it’s printed on your bill, and it’s essential, because the tax office matches payments by this code, not by your name.
Why it matters so much
Here’s the trap. As the Belastingdienst’s payment guidance makes clear, if you don’t enter the correct betalingskenmerk, there’s a real chance your payment isn’t processed against your assessment. The result can be an aanmaning (reminder) and invorderingsrente (collection interest), so you end up owing more than the original bill, despite having paid. This is the same “don’t ignore the tax office” lesson as what happens if you ignore Belastingdienst letters.
How to pay correctly
The mechanics, per Rabobank’s guide to paying the Belastingdienst:
- Transfer to the Belastingdienst IBAN printed on your bill.
- Enter the betalingskenmerk in the payment-reference/description field.
- Enter it without the dots: type 1234 5678 9012 3456, not 1234.5678.9012.3456.
If you lost the code
Don’t guess. As the Belastingdienst’s payment-reference search tool shows, you can:
- Log in to Mijn Belastingdienst (with DigiD) and find the bill in your payment overview, the code is there; or
- Use the online zoekhulp betalingskenmerk, which generates it from your aanslagnummer (assessment number).
One bill, one code
A common mix-up: each aanslag has its own unique betalingskenmerk. If you get several bills, an income-tax assessment, a motorrijtuigenbelasting (road-tax) bill, a provisional voorlopige aanslag, you cannot reuse one code for another. Pay each with its own betalingskenmerk, and make a separate transfer per bill rather than lumping them into one payment, otherwise the system can’t split your money across the right assessments. If you pay by automatische incasso (direct debit) where it’s offered, the betalingskenmerk is handled for you, but for a manual overboeking it’s on you to copy it exactly.

Where it connects
The betalingskenmerk is core Dutch money-admin, alongside setting up the account you pay from, a joint en/of account, reading your loonstrook (payslip), the Box 3 wealth-tax terms, and checking your data in MijnOverheid.
The bottom line
When you pay the Belastingdienst, the betalingskenmerk is not optional: it’s the 16-digit code that links your money to your aanslag. Pay to the right IBAN, enter the code without dots, and if you’ve lost it, fetch it from Mijn Belastingdienst or the zoekhulp using your aanslagnummer, never just pay without it. Learn aanslag, betalingskenmerk and aanmaning, and you’ll avoid the maddening situation of paying in full and still getting a fine.

Frequently asked questions
What is a betalingskenmerk?
A betalingskenmerk is the payment reference for a Dutch tax payment: a 16-digit code that tells the Belastingdienst exactly which assessment (aanslag) your money belongs to. It’s printed on your tax bill. Because the tax office processes payments by this code, not by your name, it’s essential, you enter it in the ‘description’ or ‘payment reference’ field when you transfer the money.
What happens if I pay a Dutch tax bill without the betalingskenmerk?
Your payment may not be matched to your assessment. The Belastingdienst relies on the betalingskenmerk to process the payment in their system; without it, they may not register that you’ve paid, which can trigger a reminder (aanmaning) and extra collection interest (invorderingsrente), so you could be chased for more than you owed. Always include the exact code.
I lost my betalingskenmerk, how do I find it?
Two ways. Log in to the Belastingdienst portal ‘Mijn Belastingdienst’ (with DigiD) and find the bill under your payment overview, the betalingskenmerk is shown there. Or use the Belastingdienst’s online ‘zoekhulp betalingskenmerk’, which generates it from your aanslagnummer (assessment number). When you pay, enter the code without the dots, e.g. 1234 5678 9012 3456.
