How to calculate AHV contributions for a non-employed person with only assets during a one-month contribution period
Decisione estratta
For wealth-based assessment, the asset value at the relevant year-end is used as the basis; it is then prorated to the underyear contribution period. The BSV's method of prorating the asset base first was unlawful.
Motivazione estratta
Assets are valued at a specific valuation date and are not tied to a period like income. Prorating the asset base would double-count underyearity and could lead to the statutory annual maximum being charged for less than a year, contrary to the statute and ordinance.
