1 Deadline for filing a 2015 personal, partnership, or calendar year estates/trusts tax returns or extension.  The return or extension must be postmarked or transmitted for e-filing by Monday, April 18, 2016 (April 19 for Maine and Massachusetts residents).
In a typical year, April 15 would be the red-letter day for taxes. This year, however, April 15 has been pushed aside by April 18. April 18 is this year's deadline to file taxes or apply for an extension. Usually, when April 15 falls on a weekend the tax deadline is moved to the following Monday. April 15 falls on a Friday this year but another event, Emancipation Day, is pushing back the deadline three more days.
