Hoofdinhoud

Digipoort is the government’s central ICT hub for handling electronic message exchange between organizations and government’. It functions as an electronic post office: Digipoort receives messages, checks them against a set of requirements, and — where required, on behalf of the relevant organization — confirms receipt.

Logius is responsible for the availability, proper functioning, continuity and security of Digipoort. We manage both the Digipoort infrastructure and the associated standards.

How to connect to Digipoort 

If your organization is registered at the Netherlands Chamber of Commerce (KVK), please follow the steps below:

  1. Purchase a PKIoverheid certificate based on your KVK-number from a Trust Service Provider (TSP). The list of all TSPs that provide a PKIoverheid certificate can be found here: Logius | PKIoverheidcertificaat aanvragen (in Dutch). 
  2. Consult the table Logius | Berichtenstromen over Digipoort to determine which interface (WUS or FTP)  is needed for your Digipoort connection. 

In case of WUS-interface

Please follow the steps described in the following link Aansluit Suite Digipoort to complete your Digipoort connection.

In case of FTP-interface

Please first fill in the form in the following link Logius | Digipoort - Aanvraagformulier niet-NL. Complete your Digipoort FTP-connection by following the steps described in the link Logius | Koppelvlak FTP. Refer to these technical specifications for FTP GB 3.0 (Dutch) and FTP 1.6.1 (Dutch & English).

If your organization is not registered with the Netherlands Chamber of Commerce (KVK) you can still set-up a Digipoort connection to exchange electronic messages with the Netherlands Tax Administration by following the steps below.

Register your company as a foreign business with the Netherlands Tax Administration, via Registration form Foreign companies | Tax Administration.

Include all required documents, such as:

  • Proof of registration with your local Chamber of Commerce (if applicable).
  • A copy of your company’s deed of incorporation. 
    Make sure that this document is (translated) in Dutch, German or English.

After your registration is approved, you will receive a Fiscal Identification Number (FInr).

Register your organization in the OIN Register at Logius via Logius | OIN register - Aanvraagformulier OIN niet-NL (in English). You will need your FInr to complete the application.

Once approved, you will receive an OIN. Your registration will appear in the OIN Register.

Note: this step is not applicable for the GIR (GloBe Information Return): Group entities not based in the Netherlands cannot submit a GIR at the Netherlands Tax Administration via Digipoort. More information: Minimum Tax | Tax Administration.

 

Acquire a PKIoverheid certificate through a Trust Service Provider (TSP).

Currently, only DigiCert (QuoVadis Private Services) issues the required PKIoverheid server certificates for foreign organizations via Private Services Server-certificaten | PKIoverheid | DigiCert.

Important:

  • Check with the TSP how they handle organization validation and applicant authorization.
  • You will need your OIN for the application.

After approval, you will receive your PKIoverheid certificate.
