Unless you have a perfectly square wing, your tip will always stall first.
Square as in aspect ratio one or square as in rectangular?
Both aerodynamic washout and geometric washout can prevent tip stall in a tapered wing if the right amount of washout is used. Even a tapered and highly sweptback wing can avoid tip stall if enough washout is used. Sight down the wing of any modern jet transport for an eyefull of washout. The designer didn't put it there because HE was twisted.
