Kernrechtsfrage
Whether payments for development costs and know-how from the company constitute AHV-liable income from self-employment.
Extrahierter Entscheid
The payments are contribution-liable income from self-employment, not tax-free capital return.
Extrahierte Begründung
Tax authorities bind only on income assessment, not on whether a payment is contribution-liable. The claimant remained sufficiently connected to the exploitation of his long-term inventive work; he did not fully divest himself from the economic result, and the reimbursements were part of remuneration for entrepreneurial activity.
