Avoid common mistakes on your extended Oct. 15 tax filing

October 9, 2013

The drop-dead due date for procrastinating tax filers is less than a week away. You have noticed the countdown clock over there in the right column, right?


Oct 15 tax filing extended deadlineYes, that's right, the Internal Revenue Service is working with a skeleton crew, but it expects folks who got until Oct. 15 to finish filling out their tax returns to do just that by next Tuesday.

If you are an uber-procrastinator, you're pooh-poohing this post. You'll get to your 1040 on Monday, you say, or maybe Tuesday morning.

Good luck with that.

If you push off your tax filing too long, you'll be in a big hurry as the filing deadline gets even nearer. You have heard that old saying about haste making waste, haven't you?

But if you insist on waiting until the absolutely last minute, check out today's Weekly Tax Tip and its list of 10 common tax-filing mistakes to avoid.

Where we err: Math mistakes are the most common, both in April and October.

Also make sure you include all your income. Remember, the IRS gets copies of your W-2s and 1099s.

And I know all the ol' blog's readers are honest, but I must remind you that you should add in other earnings even if you didn't get official paperwork detailing the income.

Finally, double check all your information, especially where numbers are involved.

Transposed Social Security numbers could invalidate a tax credit claim. A bad bank account entry could send your expected direct deposit tax refund — and yes, some procrastinating taxpayers put off filing even when they're due money back from Uncle Sam — to the wrong account.

So give the tax mistakes tip (linked above) over on Bankrate a read, as well as check out my earlier filing mistakes post here on the ol' blog.

And good luck getting your return to the IRS on time!

Tax Season 2026 Continues!

We made it. Tax Day 2025 is finally over. For most of us. When the filing season started on Jan. 26, millions who were expecting refunds filed immediately. Most of us got our returns to the Internal Revenue Service by April 15. But plenty of taxpayers also got extensions. They are looking at an Oct. 15 filing deadline.

Those procrastinating filers aren’t a problem. In fact, the IRS appreciates taxpayers who take time to fill out their 1040 forms correctly. It also is grateful that tax submissions are spread out a bit, especially now that the IRS is a leaner agency. Processing returns is easier when they arrive throughout the year instead of in massive bunches.

But enough about Uncle Sam’s tax collection issues. The focus now is on all y’all who filed for extensions, giving you another six months to complete your return. Since your new mid-October due date will be here before you know it, let’s get started now on meeting it.

The ol’ blog is here to help you finish up your extended Form 1040. You can start with January’s tax tips page, which has links to the rest of the year’s tips by-month collections. You also can peruse various tax categories for more tailored advice by clicking on the More Tax Posts drop-down menu at the top of this (and every) page.

And to make sure you don’t miss your new filing deadline, the count-down clock below will let you know just how much time you to file by Oct. 15. At the latest.e. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
