Kernrechtsfrage
Whether 70% of bonuses paid by Company A. into Stiftung Z. qualify as AHV-insurable salary subject to contributions
Extrahierter Entscheid
The payments are in principle employer contributions under Art. 8 lit. a AHVV, but contribution liability depends on whether the tax authorities treat them as appropriate pension contributions; the case is remitted for further findings.
Extrahierte Begründung
The court rejected qualification as indirect salary, because Y. had no right to cash payment of that 70% portion. However, under the harmonization of tax and AHV law, the assessment of appropriateness for pension contributions must follow the tax authorities' treatment, which was not established in the record.
