Attention, please make an appointment to go to any of our offices.

What do the icons in front of the error messages mean?

In Intervat there are various types of error messages.  These can be classified into three categories:

erreur bloquante

Blocking error

For example, if you do not fill in box 71 or 72 in a periodic return:

You have to correct this error in order to continue to the next step.
avertissement à justifier

Warning to be justified

For example, if your periodic return has inconsistencies in boxes 81, 82, 83, 84, 85 and 59.

You can:

  • either correct the error
  • or not to correct and justify the irregularity (you may be contacted by one of our employees if they consider that your justification is not sufficient)
  • or not to correct and not to justify the irregularity (you will be then automatically contacted by one of our employees).

To add a justification, click on justification. The limit of characters for a justification amounts to 425.

In order not to justify, tick the box case à cocher pour ne pas donner de justification.


For example, if you fill in a turnover intended for small businesses in a customer list when you are not in this system:

You can take the warning into account or not.
