The Obligation for Small Businesses to Maintain Detailed Warehouse Records: The Supreme Court with Ordinance 16903/2025

The Italian tax landscape, constantly evolving, presents continuous challenges for businesses, especially smaller ones. The Court of Cassation, with the important Ordinance no. 16903 of June 24, 2025, has provided crucial clarification on a fundamental aspect: the obligation to maintain detailed analytical warehouse records for businesses under the simplified accounting regime. This ruling is an essential reference point for thousands of businesses, precisely outlining the boundaries of tax compliance.

The Regulatory Context and the Warehouse Issue

Small businesses adopting the simplified accounting regime (pursuant to art. 18 of Presidential Decree no. 600 of 1973) benefit from reduced administrative burdens. However, Article 9, paragraph 1, of Legislative Decree no. 69 of 1989 introduced the obligation to maintain detailed analytical warehouse records. The 2017 Budget Law (Law no. 232 of 2016, art. 1, paragraph 22) subsequently amended the regime, introducing the cash basis for income determination. This modification had generated uncertainty regarding the persistence of the obligation, a question to which the Court of Cassation has now responded.

In the matter of business income taxes, small businesses, which benefit from the simplified accounting regime pursuant to art. 18 of Presidential Decree no. 600 of 1973, are obliged to maintain detailed analytical warehouse records, as per art. 9, paragraph 1, of Legislative Decree no. 69 of 1989, even after the entry into force of art. 1, paragraph 22, of Law no. 232 of 2016, by compiling and drafting a specific entry to summarize final inventories among the data that do not contribute to income formation.

The Cassation's Interpretation: Obligation Confirmed

The Supreme Court has clarified that, despite the introduction of the cash basis, the obligation to maintain detailed analytical warehouse records persists. Law no. 232 of 2016 modified the methods of income determination but did not repeal the previous obligation. Detailed analytical records are fundamental for the correct recording of final inventories which, although they do not directly contribute to cash income, are essential data for a true representation of the financial situation and for the determination of other tax values. The Court of Cassation highlights the need for a "specific entry" to summarize these inventories.

Practical Implications for Businesses

This ruling requires entrepreneurs under the simplified regime to maintain a high level of attention on warehouse management. Failure to keep this documentation may expose the business to significant risks in case of tax audits, with potential sanctions and disputes. For compliant management, it is advisable to:

• Maintain detailed records of warehouse movements.
• Correctly value final inventories.
• Draft the specific accounting entry to summarize inventories.
• Consult a professional for compliance.

Conclusions

Ordinance no. 16903/2025 of the Court of Cassation is an unequivocal warning: accounting simplification does not exempt from the obligation of accurate and transparent warehouse management. This requirement is a fundamental safeguard for the correct determination of the taxable base and for the prevention of tax evasion. For entrepreneurs and their advisors, it is essential to adapt their operational practices and ensure full compliance with the law, navigating the complex world of taxation with confidence.
