A method for controlling torque reduction of a hybrid electric vehicle including a motor and an engine as a power source includes: determining whether a traction control system (TCS) is operating; calculating a demand torque of the TCS when the TCS is operating; determining an engine operating point according to the demand torque of the TCS; maintaining an engine torque according to the engine operating point; comparing a difference between the demand torque of the TCS and the engine torque according to the engine operating point with a charging limit torque of the motor; and performing torque reduction using a motor torque and the engine torque based on a result of the comparison.
