Corporate tax-filing deadline is March 15

March 13, 2012

If your business is incorporated, then you probably already know that your tax-filing deadline is looming.

As my special countdown clock there in the left column — No, not that April 17 one. Keep scrolling to just under the blurb about the IRS' small business tax calendar. Oh, all right. I've plugged it in this post, too. (UPDATE, March 16, since deadline has passed, countdown clock in left nav bar and here is gone.) — shows, March 15 is the due date for these business filings.

I file as a sole proprietor. So my Schedule C gets attached to my personal Form 1040 in April. OK, more like in October most years. Point is, strict corporate taxes are not in my tax wheelhouse.

So I'm referring all you strict business taxpayers facing Thursday's deadline to some business tax specific resources.

Jean Murray, who pens About.com's US Business Law/Taxs blog has put together a Corporate Income Tax Guide. It covers corporate tax forms, rates and filing information and has lots and lots of links. Thanks to Jean's colleague William Perez for tipping me to this great business tax collection.

Barbara Weltman, tax and business attorney and author of the annual J.K. Lasser’s Tax Deductions for Small Business, has good general business tax info, as well as things to consider if you're freaking out because you can't pay your tax bill.

The IRS also wants to reminder business filers about the small business health care tax credit.

This business credit was part of the Affordable Care Act enacted two years ago. Small employers that pay at least half of the premiums for employee health insurance coverage under a qualifying arrangement may be eligible to claim it.

For tax years 2010 through 2013, the maximum credit for small business employers is 35 percent.

Corporate filers finishing up your due-this-week returns can figure the health care tax credit on Form 8941 and claim it as part of the general business credit on Form 3800, both of which you send in with your corporate returns.

And here's something for all business (and personal) taxpayers to think about from Joe Kristan, an Iowa CPA and author of the Tax Update Blog: The real issue is whether you can back up your return when the IRS comes calling, whatever return you file.

Yes, Joe's item was part of Monday's Tax Carnival, but I felt it worth reposting here in a  business context.

I hope this helps a bit, and that this week isn't too terrible for all y'all corporate taxpayers.

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.)
