A shifting control method for a vehicle including: a shifting requirement determination step in which a controller determines whether power-on downshifting is required and whether a gear level when shifting is started is equal to or greater than a fourth gear; a first torque crossing step in which, when power-on downshifting is required from the gear level equal to or greater than the fourth gear, torque of a first clutch is decreased and torque of a second clutch is increased; a gear manipulation step in which, when the first clutch is released by the first torque crossing step, a target gear is engaged by manipulating a synchronizer while the torque of the second clutch is maintained; and a second torque crossing step in which, when the target gear has been engaged by the gear manipulation step, the first clutch is engaged and the second clutch is released.
