Effective 1 April 2010 the "Unique Notification for the establishment of enterprise" is mandatory. It was introduced by art. 9 of Law no. 40/07 and must be used for all fulfilments on the Company Register, Tax Agency, INPS (Social Security Admin.) and INAIL (National Insurance against Injuries at Work) for the start up of companies.
The purpose of the Unique Notification is to streamline the bureaucratic paperwork for opening a company. All of the relevant fulfilments, in fact, can be discharged before the Company Register.
