When I lived in St. Louis, I had a friend who paid a preparer to do his 1040EZ. That's like five minutes flat if you have to do it with a pencil, and 37 seconds in TurboTax. This guy was no intellectual slouch, either-- he had an engineering degree and wrote software for a living, and this was in the mid-80s when not just any joe did that. The mind boggles.
I just roughed out my 2006 returns in about 20 minutes flat. I'm missing a few pieces of data, one of which is critical (my mortgage interest statement), but I plugged in estimates and made notes of what I need to chase down. The hardest part of doing taxes is data-gathering.
Back when I was younger, I was completely neurotic about my taxes being precisely correct. These days, when I'm dealing with small I'm perfectly happy to slap some approximations in and be done with it. I have a couple of random bank accounts around that pay me some small amount of interest every year-- each in the $10-30 range-- and I always lose the interest statments for them. I just make up a number that's slightly higher than what I believe the total to be and slap that in, then forget about it. Sure, I'm paying a few bucks more in taxes than I need to, but I'm just helping to pay down the debt, right?
