We propose an improved method of the equation of motion approach to study the Kondo problem in spin-dependent nonequilibrium conditions. We find that the previously introduced additional renormalization for nonequilibrium Kondo effects is not required when we use a proper decoupling scheme. Our improved formulation is then applied to address the spin-split Kondo peaks when a spin current injects into a Kondo system.
