Why is severance pay a cost that grows on its own?
Every year you set aside 6.91% of gross pay for each employee. While the employment relationship continues that sum sits on the balance sheet as a severance pay provision, that is, as a liability towards staff. So far it is deferred pay: you would be paying it in any case.
The part that weighs is different. Each year the provision must be revalued by a fixed 1.5% plus 75% of inflation, and that revaluation is a cost to the business, not to the employee. On top of it sits the 17% substitute tax that the company pays on the revaluation itself. These are two items that rise with inflation — on a sizeable provision, across several financial years, the difference shows.
What changes with the Treasury Fund threshold?
This is the most frequently misunderstood point, and since 2026 it has also changed. Until 31 December 2025 the threshold was fixed at 50 employees, calculated differently depending on when the company was established. From 1 January 2026 the criterion is dynamic: company size is checked every year against the previous calendar year's average headcount, and if the threshold is exceeded the obligation starts the following year. The threshold itself steps down by law over time: at least 60 employees from 2026, at least 50 from 2028, at least 40 from 2032. Above the threshold in force, severance pay does not stay in the company: it must be paid monthly into the Treasury Fund managed by INPS. That removes the basis for the most common argument in favour of keeping it in-house, namely that severance pay remains liquidity available to the business. The calculation and payment obligations remain; access to the money does not.
Which tax levers open up with a pension fund?
On severance pay transferred to supplementary pension schemes the company deducts from taxable income a share of the amount transferred — 4%, rising to 6% for companies with fewer than 50 employees — and obtains a partial exemption from the Guarantee Fund contribution and from certain indirect charges. On the amounts transferred, the revaluation borne by the company also ceases.
The allocation, however, remains each employee's own decision: the company does not make it. What you can influence is the quality of the information you provide and any employer contribution to the fund, which is your lever and weighs on how attractive you are as an employer.
