How to log into Intervat?

You must always log in personally.

Are you filing VAT documents for at least one enterprise? You must then choose the profile on which behalf you want to access Intervat. 

Are you an enterprise employee? To be able to continue to act on behalf of the enterprise (other than with a certificate), the legal representative (or equivalent function) must also assign specific roles to you, regardless of how you log in.

Step 1: to log into Intervat

Step 2: select a profile

  • Identification screen with your different profiles

    Once you have logged in with your digital key, an identification screen appears showing your different profiles in order to get access to Intervat :

    • icône citoyen either logging “in your own name”
    • icône entreprise or on behalf of an enterprise: your enterprise(s) as well as the enterprise(s) for which you are an authorised representative


    Then click on “in your own name” or “on behalf of the enterprise” you want to represent.

    If you choose to act in your own name, the returns filed will be linked to your personal identity and not to the enterprise's VAT number.

    You can only act in your own name (without a VAT number)?

    If there is only one available profile, you are automatically redirected to Intervat without going through this identification screen.

  • Do you file returns for your own enterprise?

    On the identification screen, we recommend that you select the enterprise’s name as profile rather than act in your own name.

    • Are you the legal representative?
      • You can directly get access to Intervat and file your enterprise’s VAT returns. You don't need a mandate or a role.
    • Are you an enterprise employee? To be able to file returns on behalf of an enterprise, you must have:

    Once you have chosen your profile, you are logged into Intervat.

    The following message appears in the Intervat header: “I am logged in for my own VAT number”.

    • If you file “per file” (XML), there must be no <ns2 :Representative> and </ns2 :Representative> tags in the schema.

    • If you file “per screen”, you do not need to fill in the “Representative” section.

  • Are you filing returns for another enterprise with a VAT mandate?

    On the identification screen, select as profile the enterprise that actually has a VAT mandate for the return you are going to file. Only enterprises with a mandate are authorised to act on behalf of another enterprise.

    • Are you the legal representative?
      • You need an active VAT mandate in order to file VAT returns on behalf of another enterprise.
    • Are you an employee of an enterprise which is a legal representativ? You must have:

    Once you have chosen your profile, you are logged into Intervat.

    The following message appears in the Intervat header: " I am logged in as a mandatary".

    • If you file “per screen”, you need to fill in the “Representative” section.

    • If you file “per file” (XML), the tags <ns2 :Representative> and </ns2 :Representative> must be present in the schema.

      Please note that XML files must only contain returns from persons liable to tax for whom you have an electronic VAT mandate.

      If the XML file contains even a single return for which you are not authorised, the entire file will be automatically rejected. You will therefore not be able to submit any return contained in this file.
  • Are you filing returns for another enterprise without VAT mandate?

    If there is only one available profile, you are automatically redirected to Intervat without going through this identification screen.

    Otherwise, select “in your own name” to file the enterprise's VAT returns.

    Once you have chosen your profile, you are logged into Intervat.

    • If you file “per file” (XML), there must be no <ns2 :Representative> and </ns2 :Representative> tags in the schema.

    • If you file “per screen”, you do not need to fill in the “Representative” section.

  • Do you file returns as a trustee?

    If there is only one available profile, you are automatically redirected to Intervat without going through this identification screen.

    Otherwise, select “in your own name” to file the enterprise's VAT returns.

    Once you have chosen your profile, you are logged into Intervat.

    • If you file “per file” (XML), there must be no <ns2 :Representative> and </ns2 :Representative> tags in the schema.

    • If you file “per screen”, you do not need to fill in the “Representative” section.

  • Do you submit returns for a VAT unit, a general partnership or an ordinary limited partnership?

    If there is only one available profile, you are automatically redirected to Intervat without going through this identification screen.

    Otherwise, select “in your own name” to file the enterprise's VAT returns.

    Once you have chosen your profile, you are logged into Intervat.

    • If you file “per file” (XML), there must be no <ns2 :Representative> and </ns2 :Representative> tags in the schema.

    • If you file “per screen”, you do not need to fill in the “Representative” section.
