Come on people, we need this!!
I mean, companies already tell the government how much they pay you and how much tax they withheld. Unless you need to claim back taxes because of, say, medical expenses or charitable donations, there should be no need for us to even be concerned with such things.
IOW, send me my Norwegian-style postcard with the amount I owe, and quit catering to corner cases. (Oh, wait, Intuit's profits probably aren't a corner case, eh?)
