IRS Audit Representation: Why You Need a CPA on Your Side
Receiving an IRS audit notice is stressful — but how you respond determines the outcome. A licensed CPA representing you under Power of Attorney controls the scope of the audit, strategically responds to information requests, and negotiates any adjustments before you owe anything additional. You do not need to speak with the IRS directly.
What is IRS audit representation and why do you need a CPA?
IRS audit representation means having a licensed CPA, enrolled agent, or tax attorney communicate with the IRS on your behalf using a Power of Attorney (Form 2848). You are not required to speak with the IRS directly or attend the audit. A CPA limits the scope of examination, responds strategically to information requests, and negotiates any proposed adjustments — often reducing or eliminating the additional tax the IRS initially proposes.
- Power of Attorney (IRS Form 2848)
- IRS Form 2848 authorizes a CPA, enrolled agent, or attorney to represent you before the IRS. Once filed, all IRS correspondence goes to your representative, who communicates with the IRS on your behalf. You do not have to speak with the IRS directly during the audit process.

How to Handle an IRS Audit: 5 Steps
- 1
Read the audit notice carefully and note the deadline
The IRS notice specifies the type of audit, the tax year(s) under examination, the specific items being questioned, and your response deadline. Correspondence audits often have 30-day response windows.
- 2
Engage a CPA immediately and file Form 2848
File Form 2848 (Power of Attorney) with the IRS so your CPA can receive all correspondence and communicate directly with the examiner. Do not contact the IRS or provide documents before your representative is in place.
- 3
Gather documentation for the specific items under examination
Do not provide more than what was requested. Your CPA will review the notice, identify exactly what documentation supports each item, and prepare a response package that answers the IRS's questions without opening new lines of inquiry.
- 4
Respond to the IRS through your CPA — not directly
Never speak to the IRS examiner directly without your representative present. Everything you say can be used to expand the audit scope. Your CPA communicates in writing with carefully crafted responses.
- 5
Negotiate any proposed adjustments before signing
If the IRS proposes additional tax, you have the right to appeal to the IRS Office of Appeals before paying. Approximately 80% of audit disputes resolved at Appeals result in some reduction of the proposed assessment.
What a CPA Does That You Cannot Do Alone
Controls the Information Flow
The single biggest audit mistake taxpayers make is providing too much information. Each document you submit can create new questions. A CPA reviews every piece of documentation before it goes to the IRS, redacts unrelated items, and provides only what substantiates the specific items under examination. This is critical for preventing scope expansion.
Interprets IRS Law and Audit Technique Guides
The IRS publishes internal Audit Technique Guides (ATGs) for specific industries — restaurants, cash-intensive businesses, attorneys, real estate professionals, and many others. These guides reveal exactly what IRS examiners are trained to look for. A CPA familiar with these guides knows how the examiner is approaching your case and can build responses that directly address the IRS's methodology.
Negotiates Proposed Adjustments
When the IRS proposes additional tax (via a Revenue Agent Report or 30-day letter), you have multiple opportunities to negotiate before the assessment becomes final. Your CPA responds with supporting documentation and legal authority, negotiates with the group manager if necessary, and files an appeal to the IRS Office of Appeals if the examiner's position is unsupported.
Prevents Audit Extension Traps
The IRS frequently requests that taxpayers sign Form 872 (Consent to Extend the Period of Assessment) before the statute of limitations expires. While sometimes necessary, signing without strategy can expose additional years or give up valuable leverage. A CPA evaluates each extension request carefully and may negotiate limited extensions covering only specific issues.
Your Rights During an IRS Audit
The Taxpayer Bill of Rights (IRC §7803) gives you specific protections during any IRS examination:
- Right to representation: You may have a CPA, enrolled agent, or attorney represent you at any time during the audit. You can stop an IRS interview at any time to consult with your representative.
- Right to an appeal: You have the right to appeal any proposed adjustment to the IRS Office of Appeals, which is independent of the examining division.
- Right to challenge IRS positions: You can challenge the IRS's conclusions in Tax Court (before paying) or in federal district court or the Court of Federal Claims (after paying and filing for refund).
- Right to finality: The IRS generally cannot re-examine the same items for a tax year that has already been audited and closed without substantial justification.
- Right to privacy: IRS inquiries must be no broader than necessary to determine the correct tax liability. The IRS cannot request information about topics unrelated to the return items under examination.
What Happens After the Audit Closes
An audit can close with three possible outcomes:
- No change: The IRS accepts your return as filed. No additional tax is owed. The audit is closed.
- Agreed adjustment: You agree with the proposed changes, sign Form 870, and pay any additional tax, penalties, and interest. No further appeal rights are preserved once you sign.
- Unagreed: You disagree with the proposed adjustment. The IRS issues a 30-day letter giving you 30 days to request an Appeals conference. If no agreement is reached at Appeals, the IRS issues a Statutory Notice of Deficiency (90-day letter), and you have 90 days to petition the Tax Court.
Your CPA will recommend whether to agree, appeal, or litigate based on the legal merits of the IRS's position, the amount at stake, and your risk tolerance.
