I didn't agonize over every penny, so I hope I did it right. There was a moment of panic when E-file found 2 errors, but it just wanted me to put my city and state in some part of the form. And I won't go into how TaxCut wouldn't let me update when I first installed due to a McAfee conflict which I eventually got around.
My income in 2005 was about half that in 2004, when I worked full-time almost the entire year (we had "Super Millionaire" filling the time normally spent in hiatus). That's OK.
