The Postal Service will collect and postmark returns until midnight.

The IRS warned taxpayers that rushing to meet the deadline can cause errors, often very simple ones such as neglecting to sign your return or bungling your Social Security number.

Anyone needing more time can extend the deadline by four months.

The IRS said it expected 9 million extension requests.

But extensions don't relieve taxpayers of the necessity to pay any taxes owed.

If you've waited until the April 15 deadline to begin filling out your tax forms, you may run out of time.

The National Taxpayer's Union said it estimates it takes almost 27 hours to prepare the Form 1040 and its most common supporting schedules.

There are numerous ideas floating around Capitol Hill on how to streamline the process and change the tax system.

Some Republicans want to eliminate the IRS and abolish tax returns and the current tax system.

Congressman Mike Pence said he wants a "flatter and fairer" system that eliminates the "tyranny of anxiety" that everyone feels on April 15.

The President's Advisory Panel on Federal Tax Reform plans to issue a report in a few months.

On the eve of the April 15 deadline, a new survey was released showing taxpayer discontent with the current tax system.

The survey was commissioned by the Tax Foundation and conducted by Harris Interactive.

The survey found that 59 percent of U.S. adults believe they pay more federal income tax as a percentage of income than billionaire Donald Trump and 70 percent said they either "hated" or "disliked" doing their income taxes.

Other results found that a majority of those surveyed believe that federal taxes are too high, too complex, and the value received from the federal government is poor.

A majority also said they favor tax reform and were willing to give up some deductions and exemptions if it leads to a simpler tax code.
