While the link provided by tagteam references a due date, the date has not been updated to reflect the 2016 filing season. However, because due date is April 17th and this is Emancipation Day, the due date for the 2016 form is April 18, 2017.
The link should also be sufficient to show the beneficiaries that the due date is in April and not January.
This assumes the tax year is a calendar year.
