November 28, 2016

Between ACA reporting and changes to IRS filing deadlines, employers and taxpayers may be crunched at the start of the year to meet new due dates. Here are the dates you need to know – and be prepared to meet.

In addition, more than 20 states have January due dates for submitting W-2s to the state. It’s best to check with each state for deadlines, as well as the threshold for electronic filing. Kansas’ deadline to have W-2s submitted to the state is the last day of February (for 2017, Feb. 28).

January 31 Deadlines


  • W-2s submitted to employees (no change in this date)
  • W-2s submitted to the Social Security Administration (both paper and electronic submission)


  • 1099s provided to recipients (no change in this date)
  • Certain Forms 1099-MISC (those reporting non-employee compensation in Box 7) submitted to IRS
