The BZB program implements various programs such as, the wrongly rejected requests regarding Amicable Debt Restructuring Natural Persons (MSNP), the subsidy scheme Temporary Block Connection Allowance (TTB), the digital additional damage route for DGH (Feniks), and the Access to Tax File (IFD).

The MijnHerstel project: The MijnHerstel route is one of the routes for submitting additional damage for victims of the childcare allowance problem. The assignment for MijnHerstel has been provided by DGH to BZB. The activities focus on the one hand on the integral management of production in the entire chain (including coordination with DGH, UHT, and CWS) and on the other hand on the development of both the application portal and the MijnHerstel route. In addition, BZB manages the implementation of the MijnHerstel route and is responsible for its continuous improvement.

Additional Information

When you, as a supplier, offer a professional to us and they are placed, we need information from you as a contracting party, including regarding the Chain and Principal Liability Act.

The 'WKA' aims to prevent abuse in the remittance of payroll taxes at all links in the chain; from supplier to client. We cover these risks for our clients by means of a blocked account, the G-account. This is an account to which a portion of the invoice amount is deposited and from which you can pay payroll taxes and VAT to the Tax Administration. The percentage to be deposited depends on whether you have a SNA certification (NEN-4400-1 or NEN-4400-2) or not, and whether your company is located in the Netherlands or abroad. You can request the G-account from the Tax Administration.

If you cannot obtain a G-account (and you can provide proof from the Tax Administration), you also have the option to provide an accountant's statement (assurance report regarding personnel lending) every quarter. In this, a certified accountant (AA or RA) will issue a statement about the correctness, completeness, and timeliness of the remittances. Please note that the costs for this statement are at your own expense.
