Yes I have begun work on a tax project called LeTax. It has a homepage of course. At this point is is mostly bluster and posturing. However, I recommend anyone interested in this project start by reading IRS publication 17 available at also in PDF form from http://www.irs.gov/
Tax code is a maze of twisty passages, all alike. Developing this software is some of the most unfun programming I have ever done. Others are correct in pointing out that this is a huge task. However, I especially like the way that tax software code can reverse-engineer the legal system. Please read the homepage if you want to hear my rants. In a more perfect world, the IRS would be spending its resources developing this kind of software; instead they post the Tax Tables as GIFs. Feh.
I am continuing to work on this project and would greatly appreciate additional developer support. Please contact me if you are interested at coordinator@letax.org
In any case, do not play on using LeTax for the '99 tax year!
