Did you already find more information about this? I'd be also interested in getting some clarity to this issue. The only piece of information I managed to find myself is this short excerpt from taxation.ch:
| Quote: |  | |
| Residents without any professional activity (e.g. students or retired people) have to pay social security contributions up to the age of 64 (women) and 65 (men). The contribution depends on (a) the pension income and (b) the world-wide net wealth. The maximum annual contribution per person is CHF 10'300. | |
