A method of controlling a gear shifting in a neutral gear stage for shortening a gear shifting time in the neutral gear stage when performing a gear shifting of a hybrid electric vehicle is characterized in that when a shift class of the gear shifting is determined, a hybrid control unit of the vehicle determines a shift gear ratio in the N-stage in a current state by use of a transmission (TM) output speed and a transmission (TM) input speed at a class transition time point, determines an N-stage gear shifting progressing rate by use of the determined N-stage shift gear ratio, sets time points of a start and an end of the gear shifting based on the determined gear shifting progressing rate, and controls the gear shifting speed in the N-stage with reference to a gear shifting target speed and the transmission input speed in a section of the time points of the start and the end of the speed control.
