If you woke up in a panic realizing that today is April 16, relax. You’ve got until Tuesday to file and pay your taxes without facing a penalty.

April 15 fell on Sunday this year and today is Emancipation Day, a holiday in Washington, D.C. That gives taxpayers nationwide until April 17 to get the job done.

Procrastinators can take some solace in knowing that as of Friday, 40 million Americans hadn’t filed their taxes, according to the IRS. Still, this is no time to dawdle; here are some tips for you last-minute filers:

The IRS says that electronic filing is the best way to avoid common mistakes. That’s because the software does the calculations, flags common errors and prompts taxpayers to provide missing information.

It’s quicker than dropping something in the mail. Plus, electronic filers typically get their refund faster if due one.

You can use any electronic filing method you choose, but it’s worth noting that the IRS says about 70 percent of taxpayers are eligible to file their tax return at no charge by using IRS Free File software. It can be accessed at the IRS website at IRS.gov.

Yes, it’s crunch time but try not to rush.

Lisa Greene-Lewis, CPA at TurboTax, said the most important tip for entering information is to take your time. One of the most common mistakes taxpayers make when rushing is gathering incorrect Social Security numbers for their children and spouses. Some even misspell their own names.

Instead, carefully gather and enter your Social Security number, income information and banking information, if needed.
