The Practitioner's Role in IRS Audit Representation

Audit representation is one of the most valuable services a tax practitioner can provide. When a client is audited, having an experienced representative can mean the difference between a no-change audit and a significant deficiency assessment. The practitioner's role is to: (1) protect the client's rights throughout the examination; (2) control the flow of information to the examiner; (3) present the client's position in the most favorable light; and (4) negotiate a favorable resolution when the examiner proposes adjustments.

The most important principle in audit representation is never let the client speak directly with the examiner. Clients who represent themselves in audits frequently volunteer information that expands the scope of the audit, make admissions that support the examiner's position, or provide documentation that raises new issues. The practitioner serves as a buffer — all communications go through the practitioner, and the client's exposure is minimized.

The pre-audit conference: Before the first meeting with the examiner, the practitioner should meet with the client to: (1) review the return in detail; (2) identify all potential issues — not just the ones the IRS has raised; (3) assess the strength of the documentation for each issue; (4) prepare the client for questions they may be asked; and (5) develop a strategy for each issue. This pre-audit conference is the most important meeting in the audit representation engagement.

Documentation Strategy — What to Provide and When

The documentation strategy is the core of audit representation. Practitioners must decide: (1) what documentation to provide; (2) when to provide it; (3) how to present it; and (4) what not to provide. These decisions significantly affect the outcome of the audit.

Documentation PrincipleWhy It MattersBest Practice
Provide only what is requestedVolunteering documents can expand audit scopeRespond specifically to each IDR item
Organize and label everythingExaminers appreciate organized submissionsUse tabs, indexes, and summary sheets
Provide context with documentationRaw documents without context can be misinterpretedInclude a cover memo explaining each item
Don't provide originalsOriginals can be lost or damagedProvide certified copies; retain originals
Review before submittingInadvertent disclosures can create new issuesReview every document before submission
Respond to IDRs timelyLate responses signal disorganization or evasionRespond within the IDR deadline or request extension

The Information Document Request (IDR): The examiner's primary tool for requesting documentation is the Information Document Request (IDR). Each IDR item should be responded to specifically — neither over-responding (providing more than requested) nor under-responding (failing to provide what is requested). Practitioners should review each IDR item carefully and prepare a checklist of the documentation needed for each item.

Client Conversation Script: Explaining Audit Representation

When a client calls to say they've received an audit notice, the following script has been refined through thousands of successful audit representations:

Practitioner: "Thank you for calling me right away — that's exactly what you should do. I've reviewed the notice, and here's what we're dealing with. The IRS is asking about [specific items]. This is a [correspondence/office/field] audit, which means [explain the type]. Here's what we're going to do: I'm going to file a Power of Attorney so I can speak with the IRS on your behalf. You won't need to talk to them directly — everything goes through me. We're going to pull together the documentation for [specific items], and I'm going to prepare a response that presents your position in the strongest possible light. The goal is to get through this with no change or the smallest possible adjustment."

Client: "What if they find something wrong?"

Practitioner: "That's what I'm here for. If the examiner proposes an adjustment, I'll review it carefully and challenge anything that's not supported by the law and the facts. If there is a legitimate adjustment, I'll negotiate to minimize it and make sure any penalties are abated if there's a reasonable basis for doing so. My job is to get you the best possible outcome."

Fee discussion: "For a [type] audit like this, my fee is typically $[X] for the initial response and representation through the examination. If the case goes to Appeals, there would be an additional fee of $[Y]. I'll give you a written engagement letter that spells out exactly what's included."

Case Study: Field Audit — S Corporation Reasonable Compensation

Client profile: Carlos M., age 46, sole shareholder of an S corporation providing IT consulting services. The S corporation had revenues of $380,000 and paid Carlos a salary of $48,000 — the IRS argued that the salary was unreasonably low and that Carlos was avoiding payroll taxes by taking distributions instead of salary. The IRS proposed reclassifying $120,000 of distributions as wages, resulting in $18,360 in additional payroll taxes plus penalties.

Representation strategy: The practitioner obtained: (1) industry salary surveys showing that IT consultants in Carlos's market earned $85,000-$110,000 for similar work; (2) documentation showing that Carlos worked 30 hours/week in the business (the remaining time was spent on passive investment activities); (3) a comparison of Carlos's salary to the salaries paid to employees performing similar functions; and (4) expert analysis showing that a reasonable salary for Carlos's role was $75,000-$85,000.

Negotiation: The practitioner proposed a reasonable compensation of $78,000 — a 62.5% increase from the $48,000 salary, but significantly less than the IRS's proposed $168,000 ($48,000 + $120,000). The Revenue Agent accepted $78,000 as reasonable compensation, resulting in additional payroll taxes of $4,590 — a 75% reduction from the IRS's original proposal. The accuracy-related penalty was abated based on reasonable cause.

Frequently Asked Questions

How much does audit representation cost?
Audit representation fees vary by the type of audit and complexity. Correspondence audits: $500-$1,500. Office audits: $1,500-$4,000. Field audits: $3,000-$15,000+. Complex field audits (multiple years, multiple issues) can exceed $25,000. Practitioners typically charge hourly rates of $150-$400/hour, or flat fees for defined scopes of work. The investment in professional representation almost always pays for itself in reduced deficiencies and abated penalties.
Should my client attend the audit meeting?
Generally no. Clients who attend audit meetings often volunteer damaging information or make admissions that expand the audit scope. The practitioner should attend all meetings with the examiner and control the flow of information. If the examiner insists on speaking with the client directly (which is unusual), the practitioner should prepare the client thoroughly and attend the meeting to object to inappropriate questions.
What is an Information Document Request (IDR)?
An IDR is the examiner's formal request for documents and information. IDRs must be responded to within the specified deadline — typically 30 days. Practitioners should review each IDR item carefully and respond specifically to each item. Providing more than requested can expand the audit scope; providing less than requested can result in the examiner drawing adverse inferences.
Can the examiner expand the audit to cover additional years?
Yes. The examiner can expand the audit to cover additional tax years if the examination reveals issues that may be present in other years. This is called a 'related examination.' Practitioners should be aware of this risk and assess whether the issues in the audited year are also present in other years — if so, the practitioner should be prepared to address those years as well.
