What is an RSIN number?
The RSIN number (Rechtspersonen en Samenwerkingsverbanden Identificatie Nummer in Dutch) is an identification number for legal entities and partnerships. It is the business equivalent of the Citizen Service Number (or BSN), and is used to link data between basic Dutch government registrations.
If your business is liable for VAT, you will receive a VAT number. The RSIN number makes up a third of this number.
Legal entity or partnership
If your legal form is a partnership, you receive your RSIN number upon registration with the Chamber of Commerce. You won’t have to register with the Dutch Tax and Customs Administration separately.
If you are a legal entity, your RSIN number will also be automatically generated, but you will have to register with the Dutch Tax and Customs Administration separately.
If you are a sole proprietor, your citizen service number (BSN) will serve the same purpose as the RSIN number. This has to do with the fact that as a sole proprietor, you are personally liable for all matters concerning your business (debts, assets etc.).
