Yes.
Presumptive assessment u/s. 44AD.......... means minimum 6 or 8% PROFIT.......... if want to declare any thing below section 44AB (tax audit) applicable.
But there is chance to file loss ITR for partnership firm u/s. 44AD, as tax audit not applicable......
Read: If the assessee does so, i.e., declares lower income and his actual income exceeds the maximum amount which is not chargeable to tax, (for partnership firm it is zero) then the relief from maintenance of books of account is not available and he is required to maintain the books of account as per section 44AA and further, he has to get such books of account audited as per section 44AB.
Refer: Tutorials/Section-44AD-Theory.
So, if there is no other income and total loss in the business, the firm can be assessed under presumptive asessment, i.e. tax audit liability will not be applicable as per section.44AD(5)
