Starting from April 15 2016, around 30 million of Italian citizens can present their tax returns using the pre-filled form set up by the National Revenue Agency. The prefilled form includes data about revenues, tax, expenditures, including health. The pre-filled form can be changed and corrected by the citizens before submitting it online before July 7. Special procedures have been taken in order to protect sensitive health data. It is the second year for the prefilled tax declaration. 700 millions of new data and information have been added in the 2016 version.
