A recent opinion in the ongoing litigation in the case of Clair R. Couturier makes a really important point about the distinction between a penalty and a tax. We will get to that, but I would also like to discuss the larger story of the case as I struggle with what the lesson is. I thought this case might be a good illustration of Reilly’s Second Law of Tax Planning – Sometimes it’s better to just pay the taxes – but I’m not 100 percent sure, so I will let you be the judge.

Small Mistakes With Huge Costs for Your Client’s Tax Returns
We’ve all been there. A client walks into your office and, somewhere in the conversation, you realize that a seemingly minor oversight, a missed deadline, a form nobody filed, an election nobody mentioned, has spiraled into a five- or six-figure tax problem. In my years of practice, some of the most expensive mistakes I’ve seen weren’t the result of aggressive planning gone wrong. They were small, quiet errors. The kind that happens when a deadline slips, an election isn’t made, or a form gets overlooked entirely. The tax code is unforgiving in these situations, and the IRS has little sympathy for “I didn’t know.” This article walks through some of the most common, and most costly, small mistakes that can devastate your client’s tax situation, along with practical guidance for avoiding them.
