the requirements of section 44AB and 139(1) are separate and if assessee is required to get his accounts audited u/s 44AB that doesn't mean he is required to furnish return u/s 139(1) if his GTI doesn't exceed exemption limit.
So in my opinion there is no requirement to file return in this case but audit report should be obtained on or before 30th sep of the relevent assessment year.
more replies to be waited.
