IRS Audit Reconsideration: Reopening an Audit That Went Against You

What Is IRS Audit Reconsideration?

Audit reconsideration is the IRS process for taking a second look at the results of an audit you disagree with. If an examination ended with additional tax you believe is wrong — or if the IRS filed a return on your behalf and assessed tax you never had a chance to dispute — reconsideration gives you a path to reopen the case and present information the IRS did not previously consider.

It is not a formal appeal and it is not a lawsuit. It is an administrative request that says, in effect, "you reached this conclusion without the full picture; here is what you missed." Used correctly, it can reduce or eliminate an assessment that has been hanging over you, sometimes for years.

When Can You Request a Reconsideration?

The IRS will generally consider a reconsideration request when:

• You have new information or documentation that was not part of the original audit
• You disagree with the assessment the audit produced
• You never appeared or responded because you moved, did not receive the audit letters, or otherwise missed the correspondence
• The IRS filed a Substitute for Return (SFR) on your behalf, and you now want to file your own accurate return

The Substitute for Return situation is especially common. When you do not file, the IRS may prepare a return using only the income data it has and none of your deductions or credits — almost always producing a balance far larger than what you actually owe. Filing your own return through reconsideration can dramatically cut that number.

When Reconsideration Is Not an Option

Reconsideration is unavailable in several situations, including when:

• You already paid the full amount owed — in that case you generally need to file a formal claim for refund instead
• You previously agreed to the assessment through a closing agreement (Form 906) or signed Form 870-AD
• You resolved the liability through an accepted Offer in Compromise
• The United States Tax Court or another court has issued a final decision on the same tax and year

In other words, once you have formally and finally settled the matter, the door to reconsideration is generally closed.

What You Need Before You Request

Three things put you on solid ground before you ask for reconsideration:

• A filed return. You must have filed a return for the year in question (which is exactly what you do when responding to a Substitute for Return).
• An open balance or a valid refund path. Reconsideration typically applies when tax remains unpaid. If the balance is already paid in full, the proper route is usually a refund claim.
• New, credible documentation. The IRS is reopening a closed examination, so you need to show information it did not previously see — receipts, bank records, mileage logs, corrected forms, or proof of deductions and credits.

How to Request an Audit Reconsideration

There is no single dedicated form for audit reconsideration. Instead, you build a package:

• Write a clear letter identifying the tax year and the specific audit changes you dispute
• Complete Form 12661, Disputed Issues Verification, to explain each item you are challenging
• Attach copies (never originals) of the documents that support your position
• Include a copy of your audit report (Form 4549) if you have it
• Mail the package to the IRS address shown on your audit notice or the campus that made the change

Organization matters. A reconsideration reviewer is deciding whether to reopen a case, and a clean, well-documented package tied point by point to the disputed items gives you the best chance of a favorable second look.

Tips for a Strong Reconsideration Package

• Address only what changed. Focus your evidence on the specific adjustments you dispute rather than re-arguing the entire return.
• Explain the gap. Briefly state why this information was not provided during the original audit — you moved, never received the letters, or only later located the records.
• Label your exhibits. Number your documents and reference them in your letter so the reviewer can match each proof to each disputed item.
• Keep copies of everything you send, and never mail original documents.

What Happens After You Submit

The IRS reviews your documentation and can respond in one of three ways: accept your position and abate all of the additional tax, partially agree and adjust the balance, or determine that no change is warranted. Reconsideration can take time, and collection is not automatically suspended while your request is pending — so if you are worried about levies or garnishment, you can ask the IRS to hold collection or set up an interim arrangement while the review proceeds.

If Your Reconsideration Is Denied

A denial is not the end of the road. You can request that the case go to the IRS Office of Appeals for an independent review by an officer who was not involved in the original decision. Alternatively, you can pay the tax and file a formal claim for refund, and if that is denied, pursue the matter in court. Because each of these paths has its own deadlines and strategy, this is a point where professional representation can make a real difference.

It also helps to keep the collection statute in mind. The IRS generally has ten years from the date of assessment to collect a tax debt, and an unresolved audit assessment continues to accrue interest and penalties the whole time. Pursuing reconsideration promptly — rather than letting the balance sit — protects your options and keeps the amount at stake from ballooning while you work toward the correct number.
