When is a business really a business? As Supreme Court Justice Potter Stewart said in 1964, “I know it when I see it.” The US Tax Court, however, maintains a slightly less subjective standard. The Roots were pretty sure they were running a bona fide business; the IRS, however, didn’t share the sentiment. And since we’re reading about them in a segment called “Lessons Learned,” one should assume it did not go the way the Roots would have liked.

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.
