I completed our taxes last week. Yes, I procrastinated. Usually I do our taxes by hand, but this year I used
Tax Geek. It's open-source tax software. The idea is pretty simple--combine some html, perl scripts, and some pdf manipulation. It downloads pdf versions of the tax forms from the IRS, and then generates copies with your tax information overlaid on top.
It worked great for me, except for one schedule which didn't print right, so I filled in that one by hand; no big deal. Hopefully next year they'll get support for state taxes.
Of course, the IRS isn't interested in supporting non-commercial tax preparation software, so I still had to mail it in.
The upshot is that I get a federal refund, and we had to pay an additional $2 in state taxes. Somehow the new rule that you have to round to the nearest dollar makes me feel like I'm being nickeled and dimed.
