Kernrechtsfrage
Which AHV-taxable income basis applies for calculating the maternity allowance for a self-employed person in 2015?
Extrahierter Entscheid
The compensation office was entitled to rely on the tax authority's binding notice of CHF 6,835, rounded to CHF 7,200, because no clear error or socially relevant special circumstance was shown.
Extrahierte Begründung
Tax assessments bind social insurance authorities unless manifest errors or socially relevant but tax-irrelevant circumstances are demonstrated; the appellant's own higher calculations did not suffice.
