Kernrechtsfrage
Whether personal contributions to the claimant's own occupational pension can be deducted in full when calculating AHV-contributory income from self-employment.
Extrahierter Entscheid
The deduction is limited to the usual employer share; for self-employed persons with employees, the maximum deduction remains one half of the personal contributions, even if they assume more than 50% of employee pension costs.
Extrahierte Begründung
The wording of Art. 9(2)(e) AHVG is not clear, but the purpose of equal treatment and the established case law do not justify distinguishing between self-employed persons with and without employees. The court clarified prior case law and held that voluntary pension contributions and buy-ins are only deductible up to 50%.
