Intuit Tax Freedom Project
If you're making less than 30,000 a year go to this website and your federal tax return will be free. If you live in a qualifying state, the state return is free too. Its the same app as the online turbo tax, but its free if you make less than 30K or are in the military. Many of us unfortunatley fall in that category.
Like cospilot said if you use EZperdiem.com in conjunction with turbo tax (theres a free guide on experdiem.com) it can save you alot of money.
Also, cospilot, thanks for the discount code.
