The Italian Supreme Court of Cassation, in Ordinance No. 24972 dated 3 September 2026, upheld financial penalties against an Italian citizen who failed to complete the RW section of the annual tax return (Modello Redditi) disclosing foreign financial assets. The taxpayer, resident in San Marino, argued that her permanent residence permit issued by San Marino authorities proved she had transferred her tax residence abroad, thereby relieving her of Italian reporting obligations. The Court rejected this defense, reiterating that under Article 2 of the Italian Income Tax Test (TUIR), tax residence is determined by either registration in the municipal population registry (anagrafe) or, alternatively, by the center of vital interests and habitual abode. Mere possession of a foreign residence permit — without formal deregistration from the Italian anagrafe and concrete evidence of severed personal and economic ties — is insufficient to break Italian tax residence. The ruling aligns with a consistent line of jurisprudence (e.g., Cass. No. 18204/2021, No. 31055/2022) and serves as a stern warning to the thousands of Italians who maintain formal residency in low-tax jurisdictions while keeping substantial links to Italy.
Key Takeaways
- Anagrafe Registration Is Decisive: As long as a taxpayer appears in the Italian municipal registry, they are presumed resident for tax purposes. The burden of proof to rebut this presumption lies entirely on the taxpayer and requires both formal deregistration and substantive evidence of life abroad.
- RW Reporting Obligation Is Absolute for Residents: Italian tax residents must report all foreign-held financial assets, accounts, and entities in the RW box regardless of whether the assets generate taxable income in Italy. Non-compliance triggers automatic penalties (up to 30% of the undeclared value) and extends the statute of limitations to seven years.
- San Marino and Other White-List Jurisdictions Offer No Safe Harbor: Even with a valid foreign residence permit, taxpayers linked to Italy through family, property, business, or habitual presence remain exposed. Professional advice and documented residency transfer steps are essential before claiming non-resident status.
