Another deadline change for this year is in Partnership and C Corporation returns.
Partnership returns Form 1065 are now due on March 15th, instead of the usual April 15th deadline. This change goes into effect in 2017 and forward.
So, now S Corporation tax return 1120S and Partnership tax return 1065 are due on the same day - March 15th.
Another change is in C Corporation return 1120 - which is now due on April 15th (this year it is April 18th).
