Questione giuridica chiave
Whether rental income from immovable property belonging to the taxpayer's business assets is subject to AVS contributions as income from self-employment rather than private wealth income.
Decisione estratta
Yes. Once the properties are part of business assets, the rental income is deemed income from self-employment and is subject to AVS contributions; no separate inquiry into whether the letting activity itself is personally carried on is needed.
Motivazione estratta
The Court relied on its recent case law: business assets are, by definition, tied to self-employed activity, and income generated from them cannot be treated as private wealth income. The parallel treatment of business gains and business yields means that rental income from business property is contribution-bearing, just like gains on transfer of such assets.
