The trick to any tax preparation or tax planning engagement is to do the work as if you would have to defend it in an audit. And when it comes to an audit, “Google said I could” is about as defensible as saying “I saw it on TikTok,” “I read it on Reddit,” “My cousin's friend said I could,” or the Twinkie Defense. What you need to defend in an audit and win is substantial authority (and really good books and records, but that is a topic for another day). This article provides some tips for conducting tax research that will get you to the authority you need.

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.

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.
