The present invention relates to a motor angle offset correcting apparatus of an electric steering apparatus and a method. The motor angle offset correcting apparatus of the electric steering apparatus of the present invention comprises: a steering angle sensor which senses a steering angle of a steering wheel; a motor position sensor which senses a motor angle of a motor of the electric steering apparatus; and a processor which calculates an offset of the motor angle and corrects the offset using a twist angle, the steering angle, and the motor angle caused by mechanical twist of the steering angle and the motor angle.
