If your looking for free tax filing options, check out the huge list of Free File sources provided by none other than the good 'ol Internal Revenue Service at IRS.gov.
Another source I found is MyFreeTaxes.com, sponsored by Walmart. This offers some options for filing both state and federal taxes for free online using software provided by H&R Block. There's even help finding free local tax help centers where you have the option of filing your taxes in person.
More local tax help may be offered at your local library or community centers, so check around.
The free tax help and free file options won't work for everyone, but they are great for those who can use them.
Happy Tax Filing!
