Aanvullende informatie

Wanneer u bij ons als leverancier een professional aanbiedt en deze wordt geplaatst, hebben we informatie van u als contractpartij nodig, onder andere met betrekking tot de Wet keten- en inlenersaansprakelijkheid. De ‘WKA’ heeft als doel om misbruik te voorkomen bij de afdracht van loonheffingen bij alle schakels in de keten; van leverancier tot opdrachtgever.

Wij dekken deze risico’s voor onze opdrachtgevers af middels een geblokkeerde rekening, de G-rekening. Dit is een rekening waarop een gedeelte van het factuurbedrag wordt gestort en waarvan u de loonheffingen en BTW kunt betalen aan de Belastingdienst.

Het af te storten % hangt ervan af of u een SNA-certificering (NEN-4400-1 of NEN-4400-2) heeft of niet en of uw bedrijf in Nederland of daarbuiten is gevestigd. De G-rekening kunt u aanvragen bij de Belastingdienst.

Indien u geen G-rekening kunt krijgen (en u kunt hier bewijs van de Belastingdienst van overleggen) dan heeft u ook de mogelijkheid elk kwartaal een accountantsverklaring (assurance report inzake inlening personeel) aan te leveren. Hierin zal een gecertificeerd accountant (AA of RA) een verklaring afgeven over de juistheid, volledigheid en tijdigheid van de afdrachten. Let wel, de kosten voor deze verklaring komen voor uw eigen rekening.
