A method for resetting an SOC of a battery in a hybrid vehicle includes calculating a first SOC value of the battery after the hybrid vehicle starts. A second SOC value of the battery is calculated using an open circuit voltage (OCV) of the battery. The second SOC value of the battery and a third SOC value for vehicle start-up are compared with each other, an SOC value of a battery management system is reset to the third SOC value when the second SOC value of the battery is smaller than the third SOC value, and the SOC value of the battery management system is reset to the second SOC value of the battery when the second SOC value of the battery is larger than the third SOC value.
