Who Can File Starting Jan. 30?

The IRS anticipates that the vast majority of all taxpayers can file starting Jan. 30, regardless of whether they file electronically or on paper. The IRS will be able to accept tax returns affected by the late Alternative Minimum Tax (AMT) patch as well as the three major "extender" provisions for people claiming the state and local sales tax deduction, higher education tuition and fees deduction and educator expenses deduction.
