Specifically:

  • Beneficiaries of the bonus expiring between March 1 and May 31, may submit their renewal application by July 31, 2020. Once the application has been accepted, after running the usual checks, the continuity of the bonus will be guaranteed retroactively, starting from the original expiry date, for 12 months.
  • From March 1 to May 31, 2020, the communication flow aimed at providing eligible citizens with information on the compensation system and the need to renew their bonus application via the online system, has been suspended.
