Under the Surface Transportation and Veterans Health Care Choice Improvement Act of 2015 that was signed by President Obama on July 31, 2015, several very important deadlines were changed for specific corporate structures, that go into effect during the 2017 tax filing season for the 2016 year-end tax returns.
The new deadlines for calendar year-end tax returns are as follows:
Partnerships (Form 1065) – new deadline is 3/15, extended deadline is 9/15
C Corporations (Form 1120) – new deadline is 4/15, extended deadline is 10/15
Foreign Bank Account Reports (FBAR Form 114a) – new deadline is 4/15, and now has an extended deadline is 9/15 (the deadline to file this form previously only had one deadline with no extension available)
S Corporations (Form 1120S) – deadline has not changed and is still due by 3/15 with an extended deadline of 9/15
These returns no longer qualify for the extended due date of March 31 for filing electronically. The due date is accelerated to January 31, effective for returns and statements beginning after December 18, 2015.
The due date for filing Form 1099-MISC was generally by the last day of February for paper forms and by March 31 if filing electronically. Starting in 2017, however, for Forms -MISC related to calendar year 2016 and after, the due date for filing Forms -MISC that report nonemployee compensation in box 7 is January 31.
