Don't ignore the IRS
The key to surviving last-minute tax filing is realizing that the IRS will not be ignored.
These guys aren't kidding around when they set deadlines. The IRS wants your paperwork, and it wants it now. If you don't file your return today and you owe taxes, you may owe an additional penalty for failure to file unless you can show reasonable cause. The assessment is 5% per month (or any part of a month, even just a day) of your balance due.
Even if you file on time but don't pay what you owe, the IRS can charge you. This nonpayment penalty is one-half of 1% of the tax due each month, or any part of a month, that isn't paid. The fine continues until it reaches 25% of your late payment.
If both penalties apply in any month, you get a small break on the failure-to-file penalty. The IRS will reduce it by what it's charging you for not paying, making your potential maximum nonfiling penalty "only" 22.5%.

Not filing your return will cost you an additional 5% each month of any due tax.
Not paying what you owe will add an extra charge of 0.5% each month of your due tax amount to your overall IRS debt.
If you don't file or pay for five months, the 0.5% failure-to-pay penalty will accrue, up to 25% of what you owe, until the tax is paid.
In that case, the total penalty for failure to file and pay could amount to 47.5% of your tax bill.
If you file your return more than 60 days after the due date or extended due date, the minimum penalty is the smaller of $135 or 100% of the unpaid tax.
Interest also is charged on the overdue amount.
But when you combine the late-filing and nonpayment penalties, even with the IRS "discount" on the late-filing charge, your total tax penalties could be substantial if you continue to ignore your tax responsibilities. Put off filing and paying for five months, and the 0.5% failure-to-pay penalty continues to run, up to 25%, until the tax is paid. This means your total penalty for failure to file and pay could amount to a whopping 47.5% (22.5% for late filing, 25% for late payment) of the tax owed.
The IRS also charges interest on the amount of tax due. The rate is the federal short-term rate plus 3 percentage points and is adjusted quarterly.
And if your return is more than 60 days late, the minimum failure-to-file penalty is the smaller of $135 or 100% of the tax required to be shown on the return.
Interest charges also will continue to add up -- on the penalties, too. So let's get started and get your taxes done!
Another Shot at Postponement
Since you've waited this long, you might be inclined to put off the inevitable a bit longer. Guess what? You can -- sort of.
The IRS will wait for your return until Oct. 15 if you file for an automatic extension. You can do this by sending in Form 4868, Application for Automatic Extension of Time to File. You can e-file the extension request from your home computer or have your tax professional who is an IRS authorized e-filer do so for you. Regardless of which method you choose, the extension request also must be made by April 18, or postmarked with that date if you snail mail it.
The extension will give you six more months to get your tax act together. But you don't have to wait until that ultimate deadline. Any time you get your tax filing material in order before then, you can send in your 1040.
Filing this form won't delay any money you owe Uncle Sam. While he'll wait patiently for your paperwork if you ask, he wants the money on its way today or all those interest and late-payment fees will be tacked on to your final bill.
How do you know how much to send? You don't have to be precise. As long as the amount comes to 90% of what you eventually owe when you crunch all the numbers, you'll be OK with the IRS.
The easiest way to estimate the amount to pay is to look over last year's tax return. If your financial and tax situation are basically the same as last year -- you have the same job, still married, two kids, deductible mortgage interest -- then what you owe this year is likely to be close to the amount you owed last year.
Choosing your form
By now, you may have decided that it's just as easy to file and be done with it. In that case, your first step is to pick which form to use. The IRS gives you three options: the 1040EZ, the 1040A and the long 1040.
If your tax life is very simple, the 1040EZ may be best for you. If you have a few items other than just your salary -- say, a student loan you've been paying interest on or an IRA contribution -- look over the 1040A. And if you have income from several different sources or plan to itemize deductions, then it's the long Form 1040 for you.
If the 1040A or 1040 works best for you, then you're probably going to have some added tax paperwork to complete, such as Schedule A if you itemize deductions or a variety of worksheets or forms if you claim some credits. Once you determine the extra forms you'll need, you can download them.

Gathering the Data
Next, track down all your income documents -- W-2 salary and wage statements, reports on how much interest you earned last year.
Don't have them all? Get in touch with your boss and the other statement issuers and request copies now. If you have to wait for the duplicates, though, make sure you file an extension application.
If you're really committed to getting your taxes done today, there's a way you can file without the forms. For interest and dividend income, pull out your last account statements. They should have the earnings information you need.
As for your missing W-2, use the data on your final pay stub from last year to complete Form 4852, the IRS' authorized income statement substitute. Then, fill out Form 4852 in place of the absent W-2.
Filling in the Blanks
Now it's time to fill in the form blanks.
The key here is making sure you don't miss any tax deductions or credits (hint: Credits are usually better since they reduce your tax bill dollar-for-dollar) that can save you some tax dollars.
The bulk of the tax breaks, such as home-related deductions, go to itemizers. But most filers actually claim the standard deduction and there are some write-offs, such as the more than a dozen above-the-line deductions, that are available to every taxpayer, regardless of which deduction method they use.
If you think you might be able to claim some deductions or tax credits but are having trouble finding all those receipts to substantiate your claim, consider filing that extension request so you'll have a few more months to sort through the stack of tax documents in the corner.
The home stretch
Oh, wait! You just found the receipt you needed, so it's time to wrap up this process.
You've completed the forms, attached the required statements, made out the check, affixed your signature and sealed the envelope. Now it's time to get that tax material on its way to the IRS.
If you've done your taxes the old-fashioned paper way, head for the post office. But make sure it's a quick trip. Use the U.S. Postal Service's office locator to find the one nearest you. If it's getting late, call first to make sure the office will be open longer to collect tax returns.
Or you could dispense with paper altogether. You can download several tax software packages and use them to file electronically directly from your personal computer. If you don't want to clutter up your computer's hard drive, you can access essentially the same products online to complete your taxes via the Web. The IRS encourages this method via the Free File Alliance, which affords some taxpayers no-cost online tax prep and filing.
Of course, there's still time to take the rest of the day off and file Form 4868. It's usually better to file an extension than to send in a return riddled with mistakes.
Congratulations! You did it!
What exactly you did doesn't matter at this point as long as you send the IRS something. If you completed your taxes, take a well-deserved break.
And if it's an extension request that's on its way to Uncle Sam, we'll see you back here at Bankrate.com in October!
