So, I am being fined by the IRS. Do I have any options?

[DJ Cummins]

Good morning everyone,

So last night I got a letter in the mail saying that our business tax returns were never received, and my wife and I are each being fined $195.00. We own 3 different LLC's, and Mailed all 3 returns (prepared by our CPA) on April 4th. Apparently the other 2 business tax returns found their way to the IRS.

Do I have any options here?  Is there anyway that I can contest this?  I didn't send the paperwork as certified(that will never happen again) so I don't really have any proof.  Something tells me that they won't just take my word for it.  

I finally feel like I have a really solid grasp on this whole REI thing, and then something like this pops up, and I am not sure if there are any options for us other than just paying the stupid fine. The letter said we have to have the $390 check post marked by June 18th.

Thank you in advance!
