When an IRS dispute reaches Appeals, many taxpayers assume the hardest part is over. In reality, Appeals is often where settlement leverage either gets stronger or starts to disappear.
That matters because the IRS Independent Office of Appeals exists to resolve tax controversies without litigation and on a basis that is intended to be fair and impartial to both the government and the taxpayer, not as a second audit or a casual do-over of what happened in exam or collection. The agency’s own guidance says Appeals is designed to resolve disputes without court, and its internal manual says the Appeals process is not a continuation or extension of examination.

In practical terms, that means settlement leverage often turns on how clearly the case is framed, how well the record is built, whether deadlines are preserved, and whether the taxpayer presents the kind of factual and legal uncertainty that Appeals can realistically weigh as “hazards of litigation.” If you want a broader foundation on how this process works, it may help to start with this overview of the IRS Appeals process and settlement leverage.
In this post, you’ll learn six common IRS Appeals mistakes that can quietly weaken negotiating position, reduce flexibility, and make a tax controversy harder to resolve on favorable terms.

Appeals is different from the exam team that proposed the adjustment. The IRS describes Appeals as a fresh, objective perspective on qualifying disputes, and the agency’s materials explain that Appeals officers may consider the litigation risk of each side when trying to resolve a case administratively.

That concept matters because leverage in Appeals usually does not come from outrage, volume, or repetition. It more often comes from evidence, legal support, procedural posture, and the realistic possibility that the government could lose all or part of the issue in court. The IRS’s internal guidance states that Appeals may consider new theories or alternative legal arguments when evaluating hazards of litigation, but it also says Appeals will not develop evidence that is missing from the file to support a party’s position. IRS Internal Revenue Manual 8.6.1
So when taxpayers weaken the factual record, blur the issues, miss deadlines, or treat Appeals like another round of informal back-and-forth, they often reduce the very uncertainty that creates settlement value.
One of the biggest mistakes is approaching Appeals as if it is simply another chance to argue with the examiner from scratch.
The IRS says Appeals is not a continuation or extension of exam. That point is more important than it sounds. In Appeals, the conversation often centers less on “I still disagree” and more on “Here is the precise issue, here are the facts that matter, here is the legal authority, and here is why litigation risk exists on both sides.” IRS Internal Revenue Manual 8.6.1
Taxpayers sometimes hurt themselves by sending in the same correspondence they already used during the audit, without reorganizing the dispute around contested issues. Others flood Appeals with raw records but no narrative. Some rely on emotional fairness arguments rather than tax law, substantiation, or procedural defects.
Here’s what this often means in practical terms:
A more effective posture often looks like a focused protest or conference submission that identifies each adjustment, states the factual disagreement, ties the facts to legal authority, and explains the litigation risk. If you’re earlier in the process, a separate guide on deciding whether an exam result is worth protesting can also be useful context before leverage starts to form.
