niiler writes "There is finally a usable US federal income tax program for Linux users who don't wish to file online. TaxGeek is a Mozilla-based US income tax program that includes Form 1040, Schedules A, B, C, C-EZ, D, E, K-1 (1065), SE (Short and Long), W2, Forms 8880, 8853, 8863, 8812, 5695, 4952,3903, 2106, 2106ez, 2441 with access to most other files as PDFs. It is intended to be extensible so that developers can easily add other forms that are needed without affecting the existing file formats and stored data. TaxGeek will also create PDFs of all the supported forms so that you can print them and send them in to the IRS. (PDF creation support requires the installation of Perl PDF::Reuse.) At this point, e-filing is not supported."
