San Marino: Italian Assets Alone Insufficient to Prove Tax Residence

In a landmark ruling dated 10 August 2026, the Italian Supreme Court (Cassazione, Sez. V, Ord. 19092/2026) clarified that the mere ownership of real estate, bank accounts, or family ties in Italy does not, by itself, constitute sufficient evidence to rebut a taxpayer’s claim of foreign tax residence. The decision reinforces the principle that tax residence is determined by the “center of vital interests” test under Article 2 of the Italian Income Tax Code (TUIR) and applicable double tax treaties. The case involved an Italian citizen who relocated to the UK but maintained significant Italian assets. The tax authority argued that these ties demonstrated continued Italian residence, but the Court held that the taxpayer’s habitual abode and personal-economic relations in the UK prevailed. This ruling provides important guidance for high-net-worth individuals and expatriates managing cross-border lifestyles.

Key Takeaways

  • Center of Vital Interests Test: Tax authorities must conduct a holistic analysis of personal, family, and economic relations rather than relying on asset ownership checklists. Documentary evidence of daily life abroad (utility bills, local memberships, school enrollment) is critical.
  • Treaty Tie-Breaker Rules: For dual residents, the OECD Model Treaty tie-breaker criteria (permanent home, habitual abode, nationality) apply sequentially. The Court emphasized that treaty provisions override domestic presumptions.
  • Burden of Proof Shift: Once the taxpayer provides credible evidence of foreign residence, the burden shifts to the tax authority to prove otherwise with specific, concrete facts. Mere suspicion or asset ownership is insufficient.
