Questione giuridica chiave
How should AVS contributions for 2001 be calculated after cessation of self-employment mid-year when the tax authority communicated a full-year business result of CHF 100,000?
Decisione estratta
The contribution basis was not to be reduced pro rata to five twelfths; in the specific fiscal and evidentiary circumstances, the full tax-assessed business result for the closed exercise could be used without conversion or time apportionment.
Motivazione estratta
The Court held that the simplification advocated by OFAS applied in the special setting of cessation of independent activity, especially where the tax assessment likely included ordinary and extraordinary elements from closing operations and a pro rata conversion would be artificial and impracticable.
