ITR
Regulation & taxAlso called: Income tax return
The income tax return — ITR-1 for salary alone, ITR-2 once there are capital gains from shares or funds, ITR-3 where intraday or F&O activity makes it business income.
In plain terms
Delivery trades produce capital gains; intraday and F&O produce business income, taxed at slab and carrying audit thresholds. A few casual intraday trades genuinely change which form you file.
