Decisione estratta
No. The special AVS contribution cannot be deducted when assessing the ordinary cantonal income tax for 1993.

The contribution relates to the earlier capital gain and is charged under the special AVS regime; it does not qualify as a deductible item in the later ordinary income tax assessment.
