I've used Tax Act in Firefox on both Windows and Linux successfully.  I believe you need javascript and cookies enabled.  I've started in Windows and then finished in Linux.  There were some problems in Firefox last year or the year before and so I submitted bug reports so their Firefox support could improve.  I think I've used them for the last 3 years.

Federal e-filing is free to all, but you can upgrade to get more online help and hints to save money.  To file state costs money.  So I went to the MO Dept. of Revenue and they had a PDF that let you put in info and print the result for free.  I then printed that and mailed it off.  I did that under Windows with Acrobat so YMMV under Linux.  It was not the greatest, but will perhaps improve in future years.
 
Always print hardcopies for your own records and save 5 years worth of tax filing.

There's some IRS program called Freefile.  If you make less than $52k a year, you can choose any of these companies (http://www.irs.gov/app/freeFile/jsp/index.jsp ) and do your federal return for free online.  I used HR block online the last two years, so I was going to again, and I got THIS:

We've detected that you're using an operating system that is currently not supported by TaxCut Standard Software.

TaxCut Standard Software has been optimized for the following operating systems.

Win2000, WINXP, Win Vista, MAC OS 10.2.8, MAC OS 10.3.9 and MAC OS 10.4.8



WTF, Why do they care what OS I run?  It's a damn web application.  All they need to do is optimize for the only real browser platform, Mozilla, and It'll work anywhere someone has a web browser.  Their inflammatory remarks have angered me, and I want to choose some other company now.  Any suggestions?
