Non-deductible provisions for the incineration plant
The Court of Cassation has ruled in favour of the tax authorities against the companies
Provisions for environmental remediation costs recognised by a company to cover future ‘closure and post-closure costs’ of an incineration plant are not immediately deductible.
The Court of Cassation, in Order No. 26382 of 7 October 2026, has rejected the arguments in favour of businesses, which had come to seem to prevail on an issue of concern to many companies regarding the deductibility of costs set aside in the financial statements for environmental remediation and restoration.
The order, which follows previous rulings in favour of the company (the Milan Provincial Tax Commission and the Lombardy Regional Tax Commission), upholds the position of the Provincial Revenue Agency.
The Court of Cassation points out that, according to its established case law, such provisions do not fall within the scope of those permitted as deductions under tax legislation, the provisions of which are exhaustive: Article Article 107(4) of the Tuir establishes that deductions for provisions are exhaustive, being permitted only in the cases expressly provided for.
In essence, provisions for non-deductible risks – as they are made in anticipation of liabilities that do not meet the requirements of certainty and determinability – are subject to the provisions of Article 109, paragraph 1, Part Two of the Tuir and are therefore deductible when they become certain.
