You might be trading through your spouse/ parent's/grandparents' Demat account- in this case, there might be trading income and no other source of income since they might be homemaker/ retired/ any other reason. ITR 2 needs to be filed for capital gains and ITR3 for business income (speculative/non-speculative trading).
In this case, you can import your investments onto Quicko through our various integrations. If you do not see your broker, you can choose to upload these trades via our Capital Gain Template.
You do not need your Form 16 in case of only trading income for the individual (Form 16 is for salaried individuals). However, Form 26AS should be referred to for seeing income from any other sources and any taxes paid throughout the year.
You can click on E-file once the complete income situation is entered, and check for any validations to review and complete the return.
