If you’ve been putting off getting your taxes done and in the mail- this is it. Today is tax day and your return needs to be electronically filed or postmarked before midnight tonight unless you've managed to secure an extension.

Have you ever wondered what happens if you mail your taxes and the IRS says they didn’t get your return? Well, hate to be the one to tell you this, but unless you can show solid documented proof that you put your return in the mail by the end of the day on April 18th, too bad, so sad.

While you're in line at the Post Office waiting to mail your return tonight, here's a little something to keep in mind- it's always better to be safe than sorry and that goes for mailing your tax forms. If you haven't, definitely consider sending in your taxes via registered or certified mail so that you can show proof that you mailed your taxes on time. Yes, you'll have to spend a couple dollars to send your taxes certified or registered, but if you do this- it'll be the proof that you might need if you're forced to show that you mailed in the return when you said that you did.

You can also send in your return through DHL Express, FedEx and UPS if you're concerned about there being a record that you really did have your return in the mail in time- but double check physical delivery addresses with the IRS because those delivery services aren't able to deliver to P.O. boxes.
