dear sir / madam,
i worked for 5 month as a contract employee (road construction work) and i got salary but TDS was cut u/s 194c.

other months i did retail trading business.

1st. que.- Should contract employee treat this income as business income?

2nd que.-If yes,than should we show combined tournover and net profit In ITR 4

thank you.
