Not many Tax Court cases reach the Supreme Court. So when one does it’s exciting. And, as it happens, Commissioner of Internal Revenue v Zuch contains some practical lessons worth considering.

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.
