As of Monday, February 15, the Consell de Ibiza allows you to pay the ITV online, the Technical Inspection Fee.
When you make the appointment to have your vehicle checked at the Santa Gertrudis stations or by mobile phone at the fairgrounds, you can pay directly from their website : //itv.conselldeivissa.es with your card and thus avoid the queues at the office and go directly to the inspection lines with proof of payment.
