Section 44 AD & ab

You can declare profits below 6% / 8% as the case may be but now you need to comply eith Sec 44AA (Maintenance of Books of Accounts) and Sec 44AB (Tax Audit) 

Below 8% means how much ?
If turnover is in non-cash mode, you need to declare 6% profit minimum. Below this, don't file under 44AD. File ITR3 with PandL , Balance sheet with whatever actual profit figure. And note that there is no audit requirement as turnover is below 1 CR

Yes.... I agreed to Mr NAVEEN CHAND reply...

Yes... You can file ITR for the FY 19-20 with less than 8 percent as per Mr Naveen Chand view...

For FY 20-21 You can opt sec 44ad if all conditions are fulfilled as per section. No more restrictions based on FY 19-20 with FY 20-21...

Note : FY 20-21 reply only based in Your query...
