I just found through the IRS that most people who made less than $52,000 last year (such as myself) can get their taxes processed and filed for free through a number of different third-party accounting firms. For example, when I went to this page and filled out the info, one of the companies I could choose from to process and file my returns for last year was H&R Block. As far as I can tell, I have access to the same state and federal online filing program as if I paid them $40 (and I don't have to pay the IRS e-filing charge either).
I haven't gone through the entire process yet, but since my taxes for last year should be a breeze (for the first full year since college, I wasn't a freelance employee), I have no problem saving $50 on the filing process.
