We see this quite often and my heart goes out to you. Start by checking out this post -> www.johnrdundon.com/negligence-vs-disregard-it-matters-in-determining-if-the-accuracy-penalty-applies/

If the tax deficiency increases your tax by at least 10% of what was on the original return or $5,000, whichever is more, a 20% penalty will be added automatically in a knee-jerk reaction because IRS presumes you were negligent. The taxpayer will need to show that they were not negligent by attempting to follow the rules an/or received advice from a knowledgeable authority so if you follow the advice of your responsible preparer you should be able to avoid the penalty.

What is the accuracy penalty related to? More information is needed regarding the penalties being assessed. Without more information, it is difficult to answer your question appropriately.
