  The aim of this paper is to generalize the definition of complexity for the
static self-gravitating structure in $f(R,T,Q)$ gravitational theory, where $R$
is the Ricci scalar, $T$ is the trace part of energy momentum tensor and
$Q\equiv R_{\alpha\beta}T^{\alpha\beta}$. In this context, we have considered
locally anisotropic spherical matter distribution and calculated field
equations and conservation laws. After the orthogonal splitting of the Riemann
curvature tensor, we found the corresponding complexity factor with the help of
structure scalars. It is seen that the system may have zero complexity factor
if the effects of energy density inhomogeneity and pressure anisotropy cancel
the effects of each other. All of our results reduce to general relativity on
assuming $f(R,T,Q)=R$ condition.
