Why does Temper ask for my citizen service number (BSN)?

Clients need it for their IB47 declaration.

Even when you are yet to register as an entrepreneur, complete with a vat-ID, meaning that you are not yet obligated to declare your vat returns, it’s still possible to try Temper once. You can work one trial shift to see if becoming an entrepreneur suits you.

Clients have an annual obligation to the Tax Authorities, where they report/declare everyone they have worked with who are not registered as an entrepreneur. To do so, they use the UBD document (previously called IB47). We automatically fill in the blanks for the client and your BSN number is required as information on this form.
