Questione giuridica chiave
Whether periods before 2001 losses could be offset against self-employed income for AHV contribution purposes in 2001 and 2002.
Decisione estratta
The older losses from 1995 and 1997 could not be taken into account for the contribution years 2001 and 2002.
Motivazione estratta
After the shift to the one-year contribution and assessment period, only losses incurred and recorded in 2001 or later may be carried forward for contribution purposes; the losses relied on here predated that threshold.
