One of my friends asked this question. I post the question here to get an expert answer. For the financial year 2018-19, upto July 2018 he was under Salary category. Subsequent income comes under 194J due to his job change where he is a Software consultant. In addition, he has some profit and loss from the share market through F&O,  Intraday and a carry forward loss from the last financial year in the same F&O. Here are his questions.

1. Which ITR form he has to use to file? 

2. Some forum says to use ITR4 under presumptive tax. However, not sure if he can include the share trade P&L in it including the salary.

3.  Similarly noticed that ITR3 itself has option to include presumptive tax under 44ADA. Can ITR 3 be used to include all P&L, 44ADA and salary?
