What Is IRS Audit Reconsideration?
Getting a tax bill after an audit can feel final, particularly if you did not expect it. But such assessments are not always set in stone. When taxpayers ask what IRS audit reconsideration is, the short answer is: it is a chance to have the IRS review an audit result again.
If you still owe tax from a past audit and now have new proof the IRS did not review, you may be able to ask the agency to reopen the case. This option may help if you moved and missed the original audit letters, if credits were denied, or if the IRS made a math or processing error. As long as the balance remains unpaid, you have a window to change the outcome.
When can you ask for audit reconsideration?
You can ask for a review after the IRS makes an audit assessment and you still have an unpaid balance. You can also take this route if the IRS filed a return for you or denied the tax credits or made a basic math mistake.
This process may make sense in the following situations:
- You missed the first audit meeting
- You moved & did not get the letters from the IRS
- You have new records to share
- You believe the audit facts are incorrect
- The IRS made a math / processing mistake
It should be recognized that you cannot request such a review if you signed a closing agreement & settled with the Appeals office or have a final court decision about the tax bill.
How to request IRS audit reconsideration
The details matter. You need to gather your proof, explain each item you dispute, and send the packet to the office that handled the audit. The IRS suggests leveraging their Document Upload Tool for many requests — though you can still physically mail or fax the records.
A proper order can be presented as below:
- Read the audit report & note each item you disagree with
- Match each item to the proof — like receipts & bank statements or Forms 1099
- Write a brief explanation for every issue
- Use IRS Form 12661 if you need to present your case issue by issue
- Include a copy of Form 4549 if you have one
- Send copies of the records — never the originals — and keep a full set for yourself.
The audit reconsideration letter needs to be to the point. Indicate the tax year, point out the adjustments you disagree with, explain why — and attach the new proof. Always cover the phone number & the best time to reach you.
What should go into your packet?
The IRS looks at each disputed item on its own. Therefore, the packet should be organized to match.
A submission packet must cover:
- A brief cover letter
- Form 4549 — if you have it
- The new supporting documents — sorted by issue
- A summary page linking each document to the adjustment you dispute
- IRS Form 12661 — if you choose to use it
- Proof of mailing or a confirmation receipt for the files
The distinction between reconsideration, an appeal and Form 1040X
These 3 choices have distinct purposes, and people tend to mix them up.
Selecting the correct option at early stages saves you time. If you paid the tax in full, IRS audit reconsideration will not work for you. In such cases, you should file Form 1040X.
How long does an audit reconsideration take?
The first reply should be expected within 30 days of sending the packet. However, a full review might extend to several months long.
The IRS has the potential to pause collection efforts once they get the documentation. But collections might start again if the file does not back up your claims or if you ignore follow-up letters within 30 days. In the case of being on an installment agreement, you should continue making the payments during this time.
Who gets audited by the IRS the most?
Latest numbers present the highest examination rates contain people at the top of the income scale. For tax year 2019, the exam rate was:
- 11.0% for individual taxpayers making $10 million or more
- 3.1% for those making between $5 million & $10 million
- 1.6% for incomes between $1 million & $5 million
It does not mean the IRS ignores lower-income returns. Automated systems match records. And audits start for many reasons besides income. Even so, current data points to the heaviest audit focus on very high-income filers.
What looks suspicious to the IRS?
The IRS does not share a set of suspicious items. Further, an audit does not mean you did something wrong. Returns are generally picked through random computer screening, related audits, or when third-party documents like W-2s do not match what was filed. A refund claim alone will not automatically generate an audit process. And amending the return does not change the reasons the IRS picked the original return.
In other words, the IRS follows up when amounts do not match outside records or when a related taxpayer is under review. Very large deductions or credits or losses might also result in the IRS asking for the proof.
