This year will be the first to see the implementation of new filing deadlines for many forms. The first new deadline, that will occur shortly, is for filing W-2’s, which is now January 31 instead of the previous February deadlines. March 15 is the new deadline for Form 1065 (partnership returns) and Form 1120 (S-corporation returns). This includes the K-1s. Each is extendable to September 15.
Next comes April 15. Forms 1040 continue to be due on this date, but FINCEN 114 (Report of Foreign Bank Account) is now due at the same time instead of June 30, as in the past. Form 1041 (Income Tax Return for Estates and Trusts) and Form 1120 (Corporate Tax Return) are due on April 15 and are extendable to September 30 and September 15, respectively.
Other forms, such as Form 5471 (Report of Foreign –Owned Corporations), that are due at the same time as some of the income tax returns, will change their due dates to correspond to the new due dates of these returns. Caution is advised in checking all deadlines and not simply relying on past experience.
