How this service works
Dutch statutory extrajudicial collection costs (buitengerechtelijke incassokosten, WIK scale, Besluit vergoeding voor buitengerechtelijke incassokosten art. 2): 15/10/5/1/0.5% over the principal in brackets, minimum EUR 40, maximum EUR 6,775, optional 21% VAT when the creditor cannot reclaim VAT. Use it to compute the legally allowed collection fee on a Dutch claim.
Output
Returns the calculated extrajudicial collection fee broken down by WIK tariff brackets (15%/10%/5%/1%/0.5%), the total fee capped at EUR 6,775 and floored at EUR 40, and optionally the 21% VAT surcharge and grand total — all in EUR.
Example use cases
Creditor issuing a collection letter
“I'm sending a formal demand letter to a Dutch debtor who owes me €1,200. How much extrajudicial collection cost can I legally add under the WIK rules? I don't need VAT added.”
Accountant calculating total debt recovery amount
“One of our clients has an unpaid Dutch invoice for €8,000. What is the maximum statutory incasso fee we can charge, and please include 21% VAT since we cannot reclaim it?”
Finance team validating a debt collector's invoice
“Our collection agency is charging us €450 in buitengerechtelijke incassokosten on a €5,000 Dutch claim. Can you check if that matches the legal WIK scale?”
