Login to OneGate

We advise resident companies to log in to OneGate via CSAM, the online identification and access management portal for Belgian government services. 

CSAM is used for applications such as Intervat, Finprof, Dimona and DMFA.

Secure authentication is guaranteed through the use of an electronic identity card (eID) or the itsme® app.

Foreign companies and users must obtain a third-party electronic certificate. More information on the FAQ page.

Please note that as from 2024, it will be possible to connect to OneGate only via CSAM or with a (electronic) certificate issued by a certificate authority (CA).
