We're being asked to move from having all independent process levels to some remaining independent, and some with head/dependent process level set-up. (Currently all of our process levels are based on specific tax EIN's, and the new set-up would merge EIN's but keep non-surviving process levels in place as dependent process levels). Testing is uncovering significant issues with W2 and W2c reporting, particularly since we do lots of process level transfers and prior year adjustments every year. Does anyone have experience with changing this set-up? Is this kind of change advisable? thanks!
