If your total income is less than 2.5lks ( trading losses + all other income), you would not need an audit. But otherwise yeah, since your profit is less than 8% of turnover. And yes you can carry forward your losses if returns filed in time.
Just one more query, for FY 2016-2017 I had filed ITR but i did not do tax audit. My FnO transaction profit is less than 8% of turnover so i would require audit.
Can i do tax audit now with revised ITR ? what will be the last date of filing revised ITR with tax audit for FY 2016-2017?
