Advertising Tax: The Court of Cassation Clarifies Exemption with Order No. 16856/2025

In the Italian tax landscape, the correct interpretation of local tax regulations is of paramount importance for businesses and professionals. One of the issues that often generates uncertainty is the application of the municipal advertising tax. In this context, Order No. 16856, filed on June 23, 2025, by the Court of Cassation, presided over by Dr. S. A. M. and reported and drafted by Dr. B. M., offers essential clarification, quashing and remanding a previous decision by the Regional Tax Commission of Milan of July 18, 2018.

Article 17, paragraph 1, letter a), first period, of Legislative Decree No. 507 of 1993 must be interpreted to mean that the exemption from the advertising tax applies only when both conditions are met: the advertised activity is carried out within the premises used for the sale of the good (or the provision of the service), and the advertising activity itself is carried out within those premises. (In this case, the Supreme Court quashed the challenged decision which had deemed advertising on trolleys placed in the external area of a supermarket to be tax-exempt, as the advertising message was abstractly capable of reaching an indeterminate number of recipients, including those entirely unrelated to the business activity conducted in the commercial premises).

This ruling is of paramount importance because it establishes a
