PHOENIX - It is getting down to the wire to finish up your taxes. You only have until Tuesday at midnight to wrap everything up.

That means including Monday, there is just a little more than one day left to file your taxes. If you have not lifted a finger yet, we are sharing tips so you can avoid the IRS knocking on your door.

The Internal Revenue Service expects to receive 12 million tax returns this week, and there are a lot of resources to help, starting with the IRS's website. We break it all down for you below in five easy steps.

 1.  Not sure if you need to file? Go to “Do I need to file a tax return” on and you’ll get an answer.

2. If you do need to file and have all of the documents you need, you can also free file online at

Make sure you have your W-2 from your employer.

 3.  Not comfortable using the internet? There are dozens of places around the Valley that will be open until late Tuesday night to help.

 4.  If you can't make the deadline, file an extension. Simply use FreeFile on the IRS website to request a six-month extension.

 5.  Keep in mind, an extension of time to file is not an extension to pay. If you owe federal taxes, estimate the amount you owe and pay it to avoid penalties and interest.

If you’re using the Internet to file, experts recommend submitting no later than 9 or 10 p.m. local time Tuesday night, to avoid technology glitches.

There are post office locations offering later hours tomorrow night to help you make deadline. The Phoenix Post Office will offer a satellite drive-through drop-off location from 5-10 p.m., at the Phoenix Municipal Stadium parking lot at 56th Street and East Van Buren Street.

Full retail services will be available to customers until 10 p.m. on Tuesday at the Phoenix Main Post Office, 4949 E. Van Buren St.

The Ahwatukee, Maryvale and Sierra Adobe Stations will be open until 8 p.m. Tuesday.
