Ot23 Year 2023: Contribute to improving security

16 September 2022

Recently Inail has disclosed the revised model of the OT23  call for the year 2023.

We remind you that the call in question gives the possibility to recognize a reduction in the average rate of tariff for insurance premiums paid to INAIL in the event that the companycarries out  the improvement interventions for the prevention and protection of health and safety in the workplace.

Another condition is that the company is in compliance with the contribution and insurance obligations.

The reduction for prevention interventions is recognized upon electronic application, submitted by filling in the “OT23” form (click here)

We put below the percentages recognized

  • up to 10 workers, the reduction is 28%;
  • from 11 to 50 workers, the reduction is 18%;
  • from 51 to 200 workers, the reduction is 10%;
  • over 200 workers, the reduction is 5%.

The latest updated revision has led to the following point changes:
