Tax Return Due Dates

As a courtesy, many extended tax returns are due today. These dates have changed over the last few years and thus it is easy for all of us to get confused. Here are the dates for common returns assuming a calendar year tax year (as of today). For fiscal year returns simply adjust the month accordingly.

Individual returns (i.e., 1040):

Due date is April 15, and extension is until October 15.

Partnership and fiduciary returns (i.e., 1065 and 1041 generally for trusts):

Due date is April 15, and extension is until September 15.

Corporation returns (i.e., 1120 and 1120S):

Due date is March 15, and extension is until September 15.

Note that all such dates are extended if they fall on a Sunday, Saturday, or holiday.

Finally, a word of caution to those using professional preparers (which is the majority of taxpayers including over 60% of the individuals filing tax returns): Do not expect your preparer can handle you providing your information just before this deadline. You are not the only one who has waited until the last minute. Thus many tax return businesses assert their own earlier deadline.

And if you're late? There are penalties to pay - potentially steep ones.

Now, excuse me, but we've tax returns due today....
