Inductive Assessment and Markup Method: The Court of Cassation Clarifies with Ordinance 16901/2025

In the complex landscape of Italian tax law, the determination of business income is a subject of constant debate and fundamental importance. Often, the Financial Administration finds itself having to reconstruct a taxpayer's income in the absence or unreliability of accounting records, resorting to the tools of inductive assessment. The Ordinance of the Court of Cassation no. 16901, filed on June 24, 2025 (Rv. 675154-01), intervenes in this delicate balance, offering valuable clarifications on the application of the markup percentage method. This ruling, presided over by Dr. L. C. and drafted by Dr. A. S., quashes and remands a previous decision by the Regional Tax Commission, Taranto Branch, providing essential guidance for industry operators and taxpayers.

Inductive Assessment: A Tool for Fiscal Truth

Inductive assessment represents one of the tools available to the Financial Administration to reconstruct a taxpayer's taxable base when accounting documentation is absent, incomplete, or unreliable. Article 39 of Presidential Decree 600/1973 outlines its scope, distinguishing between "pure" and "analytical-inductive" assessment. In the former case, the unreliability or non-existence of accounting records is so severe as to make any analytical verification impossible. In the latter, despite the presence of formally regular accounting, serious and specific omissions or falsehoods are found that compromise its reliability for individual items. It is precisely on this distinction and on the application of specific reconstruction methods that Ordinance no. 16901/2025 sheds new light.

The Ruling of Ordinance 16901/2025: The Markup Method Under the Scrutiny of the Court of Cassation

The core of the Court of Cassation's ruling lies in its clear stance on the legitimacy and methods of applying the markup percentage on the cost of goods sold. The ruling of Ordinance no. 16901/2025 states:

For the purpose of determining increased business income, the method of markup percentage on the cost of goods sold is legitimate even in cases of pure inductive assessment, not only in analytical-inductive assessment, with the difference that in the former, the judgment regarding the lack or total unreliability of accounting records constitutes the prerequisite and not, instead, as in the latter, the outcome of the determination of the markup percentage.

This statement is of paramount importance. The Supreme Court reiterates that the markup percentage method – a system that estimates revenue by applying an average profit margin to the cost of goods sold – can be used in both pure inductive assessment and analytical-inductive assessment. The crucial distinction lies in when the unreliability of accounting records is ascertained:

• In pure inductive assessment: the absence or total unreliability of accounting is the starting point, the very prerequisite that justifies the application of the markup method to reconstruct income. It is not necessary to analytically demonstrate every single irregularity, but it is sufficient to note the absence or total unreliability of the records.
• In analytical-inductive assessment: the unreliability of accounting records, even if formally existing, is the outcome. The Financial Administration must first identify specific irregularities or omissions that render certain accounting items unreliable and only subsequently, for these specific parts, can it resort to presumptions and, among these, to the markup method.

This clarification, which aligns with previous rulings (such as No. 17244 of 2021 and No. 19213 of 2017), strengthens the legitimacy of the Financial Administration's actions while providing a more defined framework for taxpayers.

Practical Implications for Businesses and Professionals

Ordinance no. 16901/2025 once again underscores the importance of impeccable and transparent accounting. For businesses, the ruling highlights that the absence or severe unreliability of records can expose them to inductive assessments based on presumptions, such as average markup, which can lead to a less favorable income reconstruction compared to that derived from regularly kept accounting. The Court of Cassation, in essence, legitimizes the use of reconstruction tools even when accounting data is entirely absent, provided that the presumptions used are serious, precise, and consistent, as required by law and jurisprudence.

Conclusions

The ruling of the Court of Cassation with Ordinance no. 16901/2025 represents an important piece in tax jurisprudence. It offers clear guidance on the application of the markup percentage method in the context of inductive assessments, clearly distinguishing between the "pure" and "analytical-inductive" phases. For taxpayers, the lesson is clear: care and accuracy in keeping accounting records are not just a regulatory obligation, but a real safeguard against possible assessments based on inductive reconstructions.
