A system and a method for controlling torque intervention of a hybrid electric vehicle including a motor and an engine as power sources that includes: a driving information detector detecting a running state of the vehicle and demand information of a driver of the vehicle; a transmission control unit (TCU) requesting torque reduction while shifting of the vehicle based on a signal from the driving information detector; a traction control system (TCS) requesting torque reduction by outputting an intervention torque for preventing a wheel slip of the vehicle; and a controller controlling torque intervention by dividing a request amount of torque reduction into the engine and the motor when receiving the torque reduction request from the TCU or the TCS, wherein the controller firstly reduces a motor assist torque when a state of the motor before the torque intervention is an assist state, maintains a motor charging torque when the state of the motor before torque intervention is a charging state, and divides an additional reduction requirement in proportion to an available reduction range of the engine and an available reduction range of the motor.
