  Soft theorems for the form factors of 1/2-BPS and Konishi operator
supermultiplets are derived at tree level in N=4 SYM theory. They have a form
identical to the one in the amplitude case. For MHV sectors of stress tensor
and Konishi supermultiplets loop corrections to soft theorems are considered at
one loop level. They also appear to have universal form in soft limit. Possible
generalization of the on-shell diagrams to the form factors based on leading
soft behavior is suggested. Finally, we give some comments on inverse soft
limit and integrability of form factors in the limit $q^2\to 0$
