The effect of noncommutative space on the inertial spin current is studied. The spin dependent inertial force on an electron in an accelerating frame in the presence of a vector potential in noncommutative space is derived. We have taken the non relativistic limit of Dirac Hamiltonian through Foldy-Wouthuysen transformation for the electron in an non-inertial frame and moving in the non commutative space. The momentum space Berry curvature due to the presence of non commutativity is investigated. For a time dependent acceleration, the dependence of noncommutative parameter on the out of plane spin polarization is also studied which can provide a new expression for a bound of the $\theta$ parameter.
