How To: File Taxes for Free

All seem best for taxpayers with straightforward, uncomplicated tax returns. A few have been recommended by readers, but I have yet to try them. If you have worked with any of them, let us know the good and the bad.

The Internal Revenue Service deems that taxpayers with an adjusted gross income of $52,000 or less in 2006 can file taxes at no charge. That means 70 percent of taxpayers (95 million) can file their taxes for free. Here's a full list of IRS-approved services you can use for e-filing.
All of the following services are on that list and some basic versions are available for free for others taxpayers, too.
