Stiiiiiiiiiilll filing your taxes? Productivity 501 has a long list of sites where you can e-file for free. Note, some of the sites this blog suggests have income limits or are available only to residents of certain states.
No matter where you live, you can file free online by using the IRS’ Free File if you make less than $56,000. If you make more than that and are using forms 1040, 1040A or 1040EZ, use Free File Fillable Forms, which requires you do the math on your own.
