Specific to suppliers

When you offer a professional with us and they are placed, we need information from you as a contracting party. Among other things, with regard to the Wet Ketenaansprakelijkheid. The ‘WKA’ aims to prevent abuse in the payment of payroll taxes at all links in the chain; from supplier to end customer.

Broker parties cover these risks for their customers. To limit liability, measures need to be taken. So too by Hero. Important here is WAADI registration and use of a blocked account, the G account. This is the account into which only payroll taxes and VAT are deposited, which are then paid to the tax authorities. You can apply for the G account from the Tax and Customs Administration.

If you have any questions about this, you can always call us on 085-222 1996 or email us at defensie@hero.eu.
