Aug. 15 is not your federal tax return extension deadline; Due date is Oct. 17

August 15, 2011

Today, Aug. 15 is not the deadline for filing your individual tax return if you got an extension earlier this year to send in your Form 1040 (or 1040A or 1040EZ).

I tweeted this earlier today, but then got an email inquiry so here's the more than 140 character scoop.

Getting an automatic extension to file — but not pay; you did send the IRS any tax you owed when you filed Form 4868, didn't you? — will give you until Oct. 15 to file your forms.

Actually, this year Oct. 15 falls on a Saturday, so you get until Monday, Oct. 17 to finish filling out your return.

Just in case you're wondering what's wrong with your memory, don't. A six-month filing extension did used to be a two-step process.

Up until the 2005 tax year, you filled out Form 4868 to get four months, until Aug. 15, to complete your taxes. And then if you needed even more time, you had to file Form 2688 to get the two additional months.

For the 2005 tax year, however, which meant returns were due in 2006, the IRS changed things. This time, though, the change was for the better as the extension process was simplified, noted in that year's What's New announcement on the revised form.

4868 changes

You now make one request using Form 4868 and that gives you until Oct. 15, or the next business day if that date falls on a weekend or federal holiday, to file your federal income tax return.

As I mentioned, each year I still get a couple of questions from folks who many years ago filed for an extension when the two-step system was in place. I'm glad I get to tell them that they don't have to panic today.

But to avoid a filing frenzy in a couple more months, you can go ahead and get your taxes completed well before the October deadline. The IRS will gladly take your returns early, relatively speaking.

TAX-SAVVY WAYS 
TO WRAP UP 2026

It’s over! With October’s extended filing deadline behind us, it is now time to focus on year-end moves to reduce your 2026 tax bill. 

You’ll find ways to do just that on the Tax Tips page (see the More Tax Posts drop-down menu at the top of the blog), as well as the separate tax tip pages for each month, notably October through December. If you’re on the Tax Tips page, you’ll find a monthly list at the end of this column. If you’re on another blog page, you can head straight to the October tips; at the bottom of that tips page you’ll find links to all the other 11 months’ collections of tax advice.

Not to spoil what you’ll find in that tax advice, but it does cover such things as tax deductions for charitable donations, investment moves that could reduce tax due, and ways to max out your tax-favored retirement savings. 

Finally, as the year winds down, things get hectic. There are lots of other things to occupy our time, like the much more fun upcoming holidays. But don’t lose sight of taxes, since timing is key. To be of use, most tax moves must be made by the end of the tax year. That’s Thursday, Dec. 31, which also is the last business day of the year. 

So that you don’t miss that final tax year deadline, also keep an eye on the countdown clock below. It will keep you on top of just how much time is left to make important, tax-saving moves. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
