PGB2.0

A personal budget (pgb) is a budget that care recipients can apply for to purchase care, support, and guidance or services themselves to live independently. They can choose their own care providers and supervisors. A pgb can be applied for based on various regulations: based on the Long-Term Care Act (Wlz), the Social Support Act (Wmo), the Youth Act, and the Health Insurance Act (Zvw).

To support the implementation in the pgb chain, the PGB2.0 chain system has been developed. PGB2.0 supports the providers and the SVB in performing their legal duties and assists budget holders and care providers with the financial settlement of care tasks.

PGB2.0 includes a care domain and a financial domain that are connected via interfaces. The care domain includes portals for budget holders, SVB care providers, and providers (municipalities and care offices). In addition, the care domain has connections with the financial domain, consisting of the financial and administrative systems of the SVB.

Currently, a multi-year administrative process is underway that will lead to the structural transfer of PGB 2.0 to the SVB.

Additional Information

When you offer a professional to us as a supplier and they are placed, we need information from you as a contracting party, including regarding the Chain Liability Act (Wet keten- en inlenersaansprakelijkheid).

The purpose of the 'WKA' is 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 Authorities.

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 apply for the G-account from the Tax Authorities.

If you cannot obtain a G-account (and you can provide proof of this from the Tax Authorities), 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.
