I'm filing 3 W2's this year. When I enter 1/3, I have a normal refund amount. When I enter 2/3, I have a normal refund amount albeit a bit less. When I enter 3/3, I owe. I've tried different sites and different orders of uploading to cross compare methods, and I end up the same way every time: owing. I'm a bit confused, especially since the amounts only vary about 2% when I add different W2's.
Has anyone had a similar experience? Or could explain?
