Federal taxes are no sweat, but Certain States I Shall Not Name [in this sentence] seriously need to improve their instructions. (Pennsylvania, I am looking at you, you confusing thing. Next to you New York and its whole "round to the nearest four decimal places" pales into simplicity.)
But I never have to file taxes in Pennsylvania again! Ha!
(California residents, please don't tell me CA taxes are complicated. I am going to try very hard not to think about it until at least January.)
