Art. 31 StG · c) Attività lavorativa autonoma 1. Disposizioni generali

1. Sono imponibili tutti i redditi derivanti da un'impresa commerciale, industriale, artigianale, agricola e forestale, da una professione libera, nonché da ogni altra attività lavorativa autonoma.

2. Tra i redditi da attività lavorativa autonoma rientrano anche tutte le plusvalenze derivanti dalla cessione, valorizzazione o rivalutazione contabile del patrimonio aziendale. È equiparata alla cessione il trasferimento del patrimonio aziendale nel patrimonio privato o in imprese o stabilimenti esteri. Si considerano patrimonio aziendale tutti i beni che servono interamente o prevalentemente all'attività lavorativa autonoma. Lo stesso vale per partecipazioni di almeno il 20 percento nel capitale sociale di una società per azioni o cooperativa, se il proprietario al momento dell'acquisizione le dichiara patrimonio aziendale.

3. Se il contribuente tiene una contabilità regolare, si applica l'articolo 82 di questa legge per analogia.

4. Le plusvalenze derivanti dalla cessione di terreni agricoli e forestali facenti parte del patrimonio aziendale sono imputate ai redditi da attività lavorativa autonoma, nella misura in cui il valore dell'investimento, detratte le plusvalenze fondiarie differite ai sensi dell'articolo 132, paragrafo 1, lettera d di questa legge, supera il valore imponibile ai fini dell'imposta sul reddito. L'articolo 138 di questa legge si applica per analogia.
