A method for measuring an offset of a resolver is arranged so as to frequently measure and correct the offset of the resolver by actively performing zero current control of a motor. The method includes steps of: determining whether a torque command value of the motor and a magnetic flux value or reverse magnetic flux value of the motor respectively fall within a first range and a second range, which have been set in advance; controlling the motor to perform zero current control for a preset time period when the torque command value of the motor falls within the first range and the magnetic flux value or reverse magnetic flux value of the motor falls within the second range; and measuring the offset of the resolver for the preset time period.
