Defending a Research Memo in an IRS Appeals Conference
At an IRS Appeals conference, a contemporaneous, citation-backed research memo is the strongest evidence you can bring. Appeals settles cases on the hazards of litigation, the realistic probability that the IRS would lose if the case went to court. A memo that documents substantial authority for the position, the reasonable-cause basis under IRC 6664(c), and the absence of adverse authority shifts that probability in your client's favor. Reconstructing the analysis after the notice arrives does not carry the same weight as the file you built when you took the position.
How a case reaches Appeals
After an examination, if you disagree with the proposed adjustments, the IRS issues a 30-day letter giving you 30 days to request a conference with the independent Office of Appeals. How you request it depends on the dollar amount. For proposed changes of $25,000 or less for any tax period, a small case request is enough: a brief written statement (by letter or on Form 12203) identifying the items you disagree with and your reasons. Above $25,000, IRM 8.25.2 requires a Formal Written Protest that lays out the facts, the applicable law, and the argument in full. Publication 5, "Your Appeal Rights and How to Prepare a Protest if You Disagree," sets out the required format.
The protest is where your research memo earns its keep. A Formal Written Protest that cites the controlling statute, the relevant Treasury Regulation, and the cases on point reads very differently from one that asserts a conclusion and hopes. Appeals officers read protests for the strength of the authority, not the strength of the adjectives. Miss the 30-day window and the path narrows: the IRS issues a statutory notice of deficiency (the 90-day letter), and your client's options shrink to paying and suing for refund or petitioning the Tax Court. The protest is the better door, and the memo is what you walk through it with.
Fast Track Settlement before a formal protest
Appeals is not always the first stop. For issues still open in examination, Fast Track Settlement (IRM 8.26) brings an Appeals officer in as a mediator while the case is still in the examiner's hands, often resolving it in weeks rather than the months a formal protest can take. The documented position drives that conversation the same way it drives a traditional conference. Whether the forum is Fast Track or a formal protest, the memo is what moves the number.
What Appeals actually weighs
The Office of Appeals exists to resolve disputes without litigation. Its currency is the hazards of litigation: the probability that the IRS would lose in Tax Court. An Appeals officer can settle for less than the full proposed adjustment when the government's litigating position is weak. Your task is to make that position look weak by showing strong authority for your client's.
Appeals is also separate from the examination function. Under IRM 8.1.10, ex parte communications between Appeals officers and the examiners or IRS counsel who developed the case are restricted, so the officer is expected to evaluate the issue fresh. That independence is an opening. The officer has not lived with the examiner's theory of the case, and a clear, well-cited memo can frame the issue before the examiner's framing sets.
How the memo wins
A research memo does three things at Appeals that nothing else does.
First, it establishes the authority level of the position. If the memo shows substantial authority, meaning the position sits above roughly the 40 percent line on the strength of the statute, regulations, and rulings, the accuracy-related penalty under IRC 6662 does not apply to an undisclosed position. That takes a penalty off the table before the conference starts.
Second, it supports a reasonable-cause defense. Even where the position is adjusted on the merits, IRC 6664(c) and Treasury Regulation 1.6664-4 waive the 6662 penalty when the taxpayer had reasonable cause and acted in good faith. Reliance on a documented analysis of the controlling authority is reasonable cause. The memo is the proof that the analysis happened.
Third, it lets you test the penalty's own paperwork. IRC 6751(b) requires the immediate supervisor of the person who proposed a penalty to approve it in writing before assessment, and the Internal Revenue Manual builds that approval into penalty procedures (see IRM 20.1.1). If the file does not show timely written supervisory approval, the penalty can fall on that basis alone, independent of the merits. Asking whether 6751(b) was satisfied is a routine and frequently productive question at Appeals.
A worked example
Suppose an examiner disallowed a deduction as not ordinary and necessary under IRC 162 and attached the 20 percent accuracy-related penalty. The examiner's report treats the issue as closed. At Appeals, you bring the memo you wrote at filing. It cites IRC 162 and Treasury Regulation 1.162-1, identifies the Tax Court opinions applying the ordinary-and-necessary standard to comparable facts, and concludes the position had substantial authority. Two things happen at once. The substantial-authority showing cuts into the 6662 penalty directly. Then you ask whether the penalty carried written supervisory approval under IRC 6751(b); if the file does not show it, the penalty fails regardless of how the deduction itself comes out. The officer, weighing the hazards of litigation, now sees a documented position and a procedurally exposed penalty. That is a far better settlement posture than an unsupported deduction and a clean penalty.
A memo built for Appeals
The memo that defends well is the one you wrote when you took the position, not the one assembled after the 30-day letter arrives. To hold up, it should state the position in a sentence, identify the controlling authority by citation, address the adverse authority you found and explain why it does or does not apply, and reach a stated confidence level. Then date it. Appeals gives more weight to analysis contemporaneous with the return than to argument constructed for the conference. These are the same research standards every credentialed preparer must meet at filing; the conference simply tests whether you met them, and the due diligence checklist produces this record as a byproduct.
Cite primary sources, not summaries. An Appeals officer can verify a Treasury Regulation or a Tax Court opinion you cite. A reference to a secondary treatise carries less weight because the officer cannot check your characterization of it. Citation-backed research is the exact format Appeals is built to read.
One caution: do not arrive with a different argument than the one in your memo. Appeals can settle the issue in the file, but a position invented for the conference invites the officer to question everything else. The strength of a contemporaneous memo is precisely that it was not built for the moment. A fresh theory undercuts that credibility and can reopen issues the examiner never raised.
The bottom line
Appeals is a probability conversation. The officer is weighing how the case would go in court, and a documented, well-cited research memo moves that probability toward your client. Substantial authority defeats the 6662 penalty, reasonable cause under 6664(c) provides a fallback, and 6751(b) gives you a procedural check on the penalty itself. None of those arguments runs on memory. They all run on the file.
