RNI regulations
Employees, researchers or students who do not live in the Netherlands and have dealings with the Government of the Netherlands, or those residing in the Netherlands for less than 4 months need to register in the registratie niet ingezetenen – RNI (register of non-inhabitants) in order to obtain a provisional Burgerservicenummer – BSN (citizen service number).
All employees contracted by or working for an employer in the Netherlands must be registered with the municipality with no exception, including those who live in Belgium and Germany and work in the Maastricht Region.
TIP: If an employee registered as a non-resident has received their BSN via the RNI and their work situation is likely to exceed the allowed 4-month period, they must immediately register as a resident at their municipality. In doing so their registration will be moved trom the RNI to the BRP (Personal Records Database). If the local municipality is not informed of the change in situation, the employee will not able to carry out basic municipal administrative tasks such as applying for a DigiD, they will not be eligible for the 30% Tax Facility, and they will not be eligible for tax breaks such as rent benefit.
