Is there a site on the internet where a person can file their taxes for free?

I believe TaxAct.com does it for free if you meet certain criteria.

If not, you can check out Internal Revenue Service (http://www.irs.gov) for a listing of free tax websites.

On the IRS website slect e-file.

Agreed; however, the IRS has not yet released the list of free efile providers for 2007.

I expect they will do so sometime next week.
