143(1) -Assessment done directly be the department after making certain adjustments for deductions and tax liability etc. . 143(3) . In this kind of assessement notices are issued to the assessee and he has to reply satisfactorily of these notices and he might have to present either personally or through his authorised representative for hearing of the case. After hearing the assessee orders U/s 143(3) are passed. .
Practically... 143(1)....does not create tension in the mind of the assessee whereas 143(3) does so.
