(This message is specifically to Mr. pratik who replied to me on the above topic).
Under Section 44AD, a person may not be under an obligation to get the accounts audited u/s 44AB merely because he claims that his income is less than 8% of the turnover. The obligation arises only in case his total income exceeds basic exemption limit besides income from business as mentioned above is claimed at less than 8% of the turnover or gross receipts as the case may be.
This is not the case so for business income under section 44AE, 44BB and 44BBB. In this case, the assessee is required to get his accounts audited u/s 44AB if he claims income from business to be lower than amount estimated to be income under that sections, no matter his total income exceeds basic exemption limit or not.
