Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus therefor. Specifically, a method for supporting, by a base station, a user equipment (UE) to perform vehicle-to-everything (V2X) communication with a vehicle through a PC5 interface in a wireless communication system may include: receiving a sidelink UE information message for requesting resource allocation for the V2X communication through the PC5 interface from a UE in a limited service state; checking whether the UE has a capability to use the V2X communication with an emergency packet data network (PDN) connection or whether the UE is authorized to perform the V2X communication; and allocating a resource for the V2X communication when the UE has the capability to use the V2X communication with the emergency (PDN) connection or the UE is authorized to perform the V2X communication.
