There are several alternatives to log in:

• with a Belgian electronic identity card (eID) or an electronic card for foreigners issued in Belgium. You need your identity card, your PIN code as well as a card reader.
• with itsme^® (if you have a Belgian electronic identity card)

You do not have a Belgian eID or an electronic identity card for foreigners? You have the following options for logging in:

• You can log in via eIDAS with your own national (i.e. non-Belgian) electronic identification means recognised at European level.
  You need a ‘BIS number’ to use eIDAS. You do not have a BIS number yet? If you reside in a country that has implemented eIDAS, you will be able to obtain a BIS number when you log in to eIDAS for the first time. More information to log in via eIDAS.
• You can register by visiting a 'registration office'. Make an appointment with the “Population” department of the municipalities which have a local registration office to activate your digital keys.
• If you do not have either of those login options, you can request access to Intervat via 'ForReg'. Select the domain 'VAT/CORPORATE INCOME TAX' when you fill in the ForReg form. In 'Choice of context' choose 'on behalf of a company'. In 'Company registration number' indicate your Belgian enterprise number (as found in the Crossroads Bank for Enterprises).
