Commentary on Judgment No. 698 of 2025: Appeal of Tax Assessment between Spouses

The ruling of the Court of Cassation No. 698 of January 10, 2025, addresses a crucial issue in the context of tax litigation, particularly regarding the legitimacy of an appeal against a tax assessment notice by a co-declarant spouse. In a system where tax declarations can be filed jointly, it is essential to clarify the rights and responsibilities of each spouse concerning tax claims.

The Case in Question

In this specific case, the co-declarant, C., appealed a tax assessment notice served to spouse A., who had already received a definitive assessment. The Court of Cassation determined that, despite the definitiveness of the act against A., C. is entitled to independently appeal the notice, as the right to defense must be guaranteed to both spouses. This principle is based on Article 1306 of the Civil Code, which establishes that the judgment rendered between the tax authority and one of the solidary debtors does not have effects against the other debtor.

The Implications of the Ruling

SOLVE ET REPETE - TAX LITIGATION (DISCIPLINE FOLLOWING THE 1972 TAX REFORM) - IN GENERAL Joint declaration by spouses - Tax assessment notice - Definitiveness against one spouse - Appeal of the tax claim by the other spouse - Admissibility - Reasons. In the context of joint income declarations by spouses, the co-declarant is entitled to independently appeal the tax assessment notice served to the spouse, even if it has become definitive against the latter, as the right to defense in court regarding acts through which the tax authority enforces tax assessments based on notices served only to one spouse must be guaranteed, and, by virtue of the general principle established in Article 1306 of the Civil Code, the judgment rendered between the tax authority and one of the solidary debtors does not have effect against the other solidary debtor.

This ruling reaffirms the importance of guaranteeing the right to defense to both spouses, creating a balance between their tax responsibilities. Indeed, the possibility of appeal by the co-declarant offers essential protection against tax measures that could be unjust or erroneous.

Final Considerations

In conclusion, Judgment No. 698 of 2025 represents a significant step in the context of tax law, as it clarifies and strengthens the right to defense of spouses in tax matters. It is crucial for taxpayers to be aware of this right, especially in situations of joint declaration, to avoid finding themselves at a disadvantage due to unilateral decisions by the tax authority. The clarity provided by the Court of Cassation serves to protect the rights of taxpayers and ensure a fairer and more just tax litigation.
