The Consolidated Appropriations Act of 2016 changed the filing deadlines for various information returns, including the Form W-2 and Form 1099-MISC.
Currently, the deadline to file Forms W-2 and 1099-MISC is Feb. 29 (or March 31, if filing electronically). This remains the deadline for the 2015 reporting year.
Beginning with the 2016 reporting year, Form W-2 and Form 1099-MISC must be filed by Jan. 31 following the reporting year. In addition, there is no extended deadline if filing electronically.
See the IRS’ website for more information on new filing due dates.
