From 1 January 2026, the Synthetic Indices of Contribution Reliability (ISAC) are introduced in order to promote compliance with tax obligations. It starts with hotels and large-scale food distribution - considered among those at greatest risk of tax evasion and avoidance - and then extends the measure to other sectors with the aim of encouraging the spontaneous emergence of undeclared work.
The novelty is contained in the decree law Ministry of Labour-Ministry of Universities and Research and Ministry of the Economy approved by the last council of ministers, which, among other measures, strengthens the quality agricultural network and grants eight weeks of cassa integrazione in deroga for small fashion companies.
By August 2026 the extension of the Isacs to six more sectors
.Let us begin with the Synthetic Indexes of Contributory Reliability (ISAC), which serve to verify the congruity of the declared workforce and correspondence with the dictates of the applied CCNLs. The purpose of the ISACs is to identify and prevent the evasion of tax bases from taxation,
It is envisaged that a decree of the Minister of Labour in agreement with the Minister of the Economy, having consulted INPS and INL, by 31 December 2025, will approve the ISACs for the first two sectors, establish the bonuses to be applied, the criteria and procedures for the periodic updating of the indices, and the hypotheses for excluding the applicability of the indices for certain types of taxpayers.
The gradual extension of ISAC to at least six additional black-risk sectors, to be approved by 31 August 2026, is established.
