Questione giuridica chiave
Whether the AHV authorities were bound by the tax reporting after the tax objection proceedings.
Decisione estratta
No binding effect existed, because the claimant had no reason to challenge the tax objection decision.
Motivazione estratta
The tax objection decision effectively allowed the entire buy-ins as a private deduction, so it made no practical difference whether the other half had been treated as business expense or general deduction; therefore the claimant had no incentive to appeal tax treatment.
