The IRS has shortened the extension period from 6 to 5
months for Partnerships (including Limited Liability Companies filing as
partnerships), and Estates/Trusts that file Form 1041. This one-month
reduction is effective for returns due on or after January 1, 2009. Note
that the original due date of April 15th (for calendar year
taxpayers) has not been changed. Thus, the new law changes the extended due
date to September 15th, rather than October 15th. The
rationale for the earlier due date is that this will allow individual
taxpayers to receive their Schedule K-1s in advance of the October 15th
extended filing deadline for individual income tax returns.
