Key takeaway
What This Development Means
INAIL OT23 2027 can reduce Italian employers' insurance rates when they complete qualifying safety improvements during 2026. Businesses should choose one type-A or two type-B measures, build documentary evidence into delivery, and apply online by 1 March 2027. New options reward smoke control, emergency training and safer workplace transport systems.
How much can INAIL OT23 2027 reduce premiums?
Under INAIL OT23 2027, reductions after the first two years are 28% for up to 10 worker-years, 18% for 10.01 to 50, 10% for 50.01 to 200, and 5% above 200. During the first two years, it is 8%. Eligibility depends on meeting INAIL's administrative and safety conditions.
What evidence should employers retain?
Evidence depends on the intervention and may include invoices, commissioning records, training registers, attendance data, certificates, policies, assessments and photographs. Employers should use the model and guide, assign an owner to documents, and test completeness before applying. Unsupported claims can jeopardise the reduction when equipment was purchased or training delivered.

Italian employers can now plan 2026 safety investments against the INAIL OT23 2027 model, published on 24 July. The scheme reduces the average insurance premium rate for businesses that go beyond minimum workplace-safety requirements. Manufacturing, chemicals, logistics and construction employers can convert well-chosen prevention projects into lower premiums, but only if the measures and evidence match the model.
One High-Value Measure Or Two Supporting Measures
INAIL OT23 2027 contains 65 interventions across fatal-accident prevention, road risk, occupational disease, training, organisational management, emergency response and personal protective equipment. Thirty-five are classed as type A and 30 as type B. Eligibility requires one type-A intervention or two type-B interventions completed during 2026.
The application deadline is 1 March 2027, using an online service that INAIL plans to release in the coming months. Employers must submit supporting documentation for every claimed intervention. That makes evidence design part of the project: purchase records alone may not demonstrate training completion, equipment commissioning, workforce coverage or sustained operation.
New Incentives Target Smoke And Emergency Readiness
A new type-A measure, F-10, covers structural elements and smoke-evacuation systems designed to contain cold smoke during a fire. New type-B measure D-5 rewards training the entire workforce in emergency management and firefighting, first aid or cardiopulmonary resuscitation.
Road-safety incentives also give greater weight to practical driver training and non-mandatory vehicle technology such as ignition interlocks, fatigue warnings and emergency braking. INAIL says 30,841 businesses received reductions in 2025, saving more than €211 million.
Choose Measures With Operational Value
INAIL OT23 2027 reductions range from 28% for the smallest employers to 5% for those above 200 worker-years, with an 8% rate during the first two years of activity. Safety, finance and fleet teams should select measures that address real risk, assign evidence owners and schedule documented completion before year end.
