How do I effectively conduct an audit interview with a taxpayer or their representative?

Conducting an effective audit interview requires a balance of professionalism, active listening, and structured inquiry. Whether you are speaking with the taxpayer directly or their authorized representative (like a CPA or attorney), preparation and clear communication are key.

Here is a step-by-step guide to conducting a successful audit interview:

1. Preparation and Planning
   • Review the file thoroughly : Understand the tax return, prior history, and specific issues or discrepancies flagged for review before walking into the room.
   • Establish the scope : Define the objectives of the interview and list the core questions or documents you need to address.
   • Determine the setting : Decide whether the interview will be in-person, over the phone, or via video conference, and ensure a quiet, neutral, or professional environment.
2. Opening the Interview
   • Set a professional tone : Introduce yourself, state your role, and outline the purpose, scope, and expected duration of the interview.
   • Confirm representation : If a representative (CPA/attorney) is present, verify that a valid power of attorney or authorization form is on file.
   • Put the interviewee at ease : Acknowledge that audits can be stressful; maintaining a polite, neutral, and objective demeanor helps reduce defensiveness.
3. Core Questioning and Fact-Finding
   • Start broad, then narrow down : Begin with general background questions about business operations, bookkeeping methods, or personal income sources before diving into specific line items.
   • Ask open-ended questions : Use questions starting with "How," "What," or "Can you walk me through..." to encourage detailed explanations rather than simple "yes/no" answers.
   • Active listening : Pay close attention to both verbal responses and non-verbal cues. Let them finish speaking without interrupting.
   • Take detailed notes : Document key statements, explanations, and any promises to provide follow-up documentation.
4. Handling the Representative vs. the Taxpayer
   • Direct questions appropriately : While representatives often handle technical accounting details, the taxpayer has firsthand knowledge of day-to-day operations and intent. Direct operational questions to the taxpayer and technical/legal questions to the representative.
   • Prevent over-answering : Representatives will sometimes try to shield the taxpayer or talk around a question. Politely re-direct the question to the taxpayer if direct personal knowledge is required.
5. Closing the Interview
   • Summarize key points : Recap what was discussed, confirm any agreed-upon facts, and clearly outline the next steps.
   • Establish document deadlines : Agree upon a firm, reasonable deadline for any additional records, receipts, or schedules the taxpayer promised to submit.
   • Thank them for their time : Conclude professionally, leaving the door open for transparent communication should further questions arise.

If you'd like, let me know:

• Is this audit for an individual or a business?
• Are you dealing with a specific contentious issue (like travel expenses or unreported income)?

I can provide tailored questions or de-escalation strategies for your specific situation.

If you mean an IRS examination/audit interview, the most effective approach is to treat the interview as a structured fact-finding exercise—not as a confrontation or a checklist recital. IRS guidance says interviews are intended to develop evidence, understand the taxpayer’s financial history and operations, assess books and records, establish facts, and resolve issues.

1. Prepare before the interview

Start by reviewing the return, prior correspondence, documents already received, and the specific examination issues. Separate what you already know from documents from what still needs to be established through testimony.

Prepare an issue-oriented outline, rather than writing every question word-for-word. IRS guidance specifically recommends tailoring questions to the taxpayer and leaving flexibility for follow-up questions.

For each issue, identify:

• What you know
• What you need to establish
• What documents support or contradict it
• What questions will establish the underlying facts
• What follow-up evidence you may need

For a business, understand beforehand the basic flow of money, operations, accounting system, internal controls, and who actually performs the relevant functions.

2. Establish the ground rules

At the beginning:

• Introduce yourself and everyone participating.
• Explain the purpose and general process of the examination.
• Establish who is representing the taxpayer and the representative's role.
• Address applicable taxpayer-rights requirements.
• Explain what topics you intend to cover.
• Make the atmosphere professional and calm.

The IRS specifically emphasizes being friendly, objective, patient, and professional because an audit can be an unusual and stressful experience for a taxpayer.

If the taxpayer has a representative, don't automatically assume the representative knows the facts firsthand. IRS guidance permits interviewing a representative without the taxpayer when the representative has sufficient firsthand knowledge, but recommends determining the extent of that knowledge.

3. Start broad, then narrow

A useful questioning progression is:

Broad → specific → documentary → reconciliation

For example:

"Please walk me through how the business operated during 2024, from receiving a customer's order through receiving payment." Then narrow down:

"Who handled the billing?" "Where were those invoices maintained?" "Who deposited the payments?" "What happened when a customer paid by check?" Then test against evidence:

"Show me where those transactions appear in the books." Finally, reconcile discrepancies:

"The sales journal shows $850,000, but the bank deposits appear to total $910,000. Help me understand the difference." This approach lets the taxpayer explain the process in their own words before you introduce a potentially contradictory document.

4. Use open-ended questions

Avoid beginning with questions that effectively announce your conclusion.

Instead of:

"You didn't keep a mileage log, correct?" start with:

"How did you document business mileage during the year?" Then follow the answer wherever it leads.

IRS guidance recommends open-ended, clear, relevant and objective questions and advises limiting leading questions primarily to situations where confirmation is appropriate.

Useful follow-ups include:

• "Tell me more about that."
• "Who was responsible for that?"
• "When did that begin?"
• "How did you determine that amount?"
• "What records were created?"
• "Where are those records maintained?"
• "Who else would have firsthand knowledge?"
• "What happened next?"
• "Can you give me an example?"
• "What do you mean by ___?"

5. Listen more than you talk

One of the biggest mistakes in an audit interview is moving immediately to the next prepared question.

When an answer is vague, incomplete, or unexpected, pause and explore it. IRS guidance specifically says the interviewer should adapt the outline, listen carefully, and develop new questions as facts emerge.

A short pause after an answer can be valuable. Don't rush to fill the silence.

Also distinguish between:

• "I know" — firsthand knowledge
• "I believe" — inference
• "I was told" — hearsay
• "That's what the records show" — documentary knowledge

That distinction can matter when evaluating the reliability of an explanation.

6. Test important assertions

Don't necessarily accept or reject an explanation during the interview. Develop enough facts to test it.

For example, if the taxpayer says an expense was entirely business-related, explore:

• What was purchased?
• Who used it?
• Where was it used?
• When?
• How was the business portion determined?
• Who approved it?
• How was it recorded?
• What supporting records exist?

Then compare the testimony with the books, bank records, invoices, contracts, third-party information, and other evidence.

IRS guidance specifically notes that information obtained through interviews should be verified through documents, observations, or other appropriate examination techniques when reliability is in question.

7. Handle the representative strategically

A representative can make the interview more efficient, particularly when they have firsthand knowledge. But distinguish knowledge of the taxpayer's affairs from knowledge of the tax return.

Ask the representative questions such as:

• "Were you involved in the taxpayer's day-to-day operations?"
• "Did you prepare the books?"
• "Did you prepare the return?"
• "Who maintained the underlying records?"
• "Were you present when these transactions occurred?"
• "Who can explain this process firsthand?"

If the representative doesn't have firsthand knowledge of an important factual matter, identify the person who does and determine what additional interview or evidence is appropriate. IRS procedures specifically address situations in which the taxpayer's presence may be requested.

8. Control the interview without becoming adversarial

If the taxpayer or representative goes off-topic:

"That's helpful background. I'd like to come back to the issue of the $75,000 deduction." If they give a long answer that doesn't address the question:

"I understand. Let me narrow the question. Who actually made the deposit?" If they repeatedly answer "I don't know":

"Who would know?" "What records could establish that?" "When was the last time you reviewed this?" The objective is complete factual development, not winning an argument.

9. Close each issue before moving on

Before leaving an important subject, summarize:

"Let me make sure I have this correctly. You are saying that the $40,000 payment was made in March, it was for consulting services, the services were performed by ABC LLC, and you have an invoice and bank record supporting the payment. Is that accurate?" This gives the taxpayer an opportunity to correct a misunderstanding and creates a much clearer record.

10. Document immediately afterward

Good interview documentation should allow another examiner to understand what happened without having been present.

Record:

• Date, time and location
• Everyone present
• Issues discussed
• Material questions and answers
• Important admissions or explanations
• Documents identified or produced
• Unresolved questions
• Follow-up information requested
• Your understanding of significant factual assertions

IRS guidance recommends brief notes during the interview rather than allowing note-taking to interfere with the conversation, followed promptly by a memorandum or other appropriate documentation. It also cautions against interpreting the taxpayer's words rather than recording and clarifying the facts.

A practical interview framework

You can structure most interviews around this sequence:

1. Purpose — Why are we meeting?
2. Background — Who is the taxpayer and what does the business/activity look like?
3. Operations — How does it actually work?
4. People — Who performs each important function?
5. Records — What records are created and maintained?
6. Controls — Who authorizes, records, reconciles and reviews transactions?
7. Issue development — What facts relate to each examination issue?
8. Evidence — What documents or third-party information corroborate those facts?
9. Exceptions — What doesn't fit the expected pattern?
10. Follow-up — What remains unresolved?
11. Summary — What did everyone agree was established, and what evidence is still needed?

The key mindset is: prepare thoroughly, ask neutrally, listen carefully, follow the facts, corroborate important assertions, and document precisely. That combination produces an interview that is both more efficient and more defensible.

If you're conducting these interviews as an IRS examiner, state tax auditor, or private-sector tax professional, the exact procedures and taxpayer/representative rights can differ; the IRS-specific points above should not be assumed to apply unchanged outside an IRS examination.

"Who would know?" "What records could establish that?" "When was the last time you reviewed this?" The objective is complete factual development, not winning an argument.

Before leaving an important subject, summarize:

"Let me make sure I have this correctly.

Conducting an effective audit interview requires a balance of professionalism, active listening, structured preparation, and interpersonal tact. Whether you are speaking with the taxpayer directly or their authorized representative (such as a CPA or attorney), here is a step-by-step guide to doing it effectively:

• Preparation , Research the taxpayer's industry, prior filing history, and known financial anomalies before stepping into the room or call. Draft a clear roadmap of questions while leaving room for organic follow-ups.
• Setting the Tone , Open with a professional, neutral, and courteous demeanor. Clearly state the purpose, scope, and estimated duration of the interview to reduce anxiety and set expectations.
• Active Listening and Observation , Listen closely to how answers are framed, not just the words spoken. Note non-verbal cues or hesitation, and avoid interrupting unless the interviewee is straying wildly off-topic.
• Open-Ended vs. Closed Questions , Use open-ended questions (e.g., "Can you walk me through the workflow for cash receipts?" ) to encourage detailed explanations, and closed questions (e.g., "Do you maintain a secondary ledger?" ) to pin down specific facts.
• Managing Representatives , Acknowledge the representative's role and direct substantive operational questions to the taxpayer when possible, as they have firsthand knowledge, while routing procedural or legal queries through the representative.
• Documenting and Summarizing , Take concise, accurate notes capturing dates, figures, and specific statements. Conclude by summarizing key takeaways and outlining the next steps or required follow-up documentation.

Would you like me to dive deeper into how to handle defensive or uncooperative taxpayers , or provide a sample checklist of pre-interview questions?

If you mean a U.S. tax audit, particularly an IRS examination, an effective interview is less about asking a long checklist of questions and more about developing reliable facts, understanding how the taxpayer actually operates, and testing those facts against the records. The IRS’s examination guidance emphasizes preparation, open-ended questioning, active listening, follow-up, and thorough documentation.

1. Prepare before the interview

Go into the meeting knowing what you need to learn and why.

Beforehand:

• Review the return, prior-year returns, workpapers, correspondence, and information already obtained.
• Identify unusual, large, inconsistent, or potentially unsupported items.
• Separate facts that are already documented from facts that require clarification and facts that can only be developed through testimony.
• Develop an interview outline organized by issue rather than a rigid list of questions.
• Identify the documents or exhibits you'll want to discuss.
• Decide what would resolve each significant audit issue.

The IRS specifically recommends tailoring questions to the taxpayer and examination issues and keeping the outline flexible rather than following a script mechanically.

2. Establish rapport and explain the ground rules

Start professionally and calmly. An audit can be stressful for the taxpayer, so explain:

• Who you are and your role.
• The purpose and general scope of the examination.
• What you'll be discussing.
• How the interview will proceed.
• What records are available or still needed.
• Relevant taxpayer rights and the examination/appeal process.

The objective isn't to make the interview adversarial. A cooperative atmosphere generally produces better information. IRS guidance specifically recommends being friendly, professional, open, calm, and objective.

3. Establish who actually has firsthand knowledge

This is particularly important when a representative is present.

Ask the representative questions such as:

• "Please describe your role in preparing the return."
• "How involved were you in maintaining the taxpayer's books?"
• "Who made the day-to-day financial decisions?"
• "Who handled the bank accounts?"
• "Who recorded transactions?"
• "Who has firsthand knowledge of the transactions we're discussing?"

A representative can generally be interviewed without the taxpayer present if the representative has firsthand knowledge of the relevant business, bookkeeping, accounting practices, and operations. However, under IRC §7521(c), an examiner generally cannot require a represented taxpayer to accompany the representative absent an administrative summons.

That distinction is important: don't confuse representation with firsthand knowledge.

4. Start broad, then narrow

A good sequence is:

Open-ended → clarifying → specific → documentary confirmation.

For example, instead of immediately asking:

"Did you deduct personal automobile expenses?" start with:

"Walk me through how the vehicle was used during the year." Then:

"Who primarily used it?" "How did you determine the business mileage?" "What records were maintained?" "Who prepared those records?" Only then move to a specific document or transaction.

IRS guidance identifies open-ended questions as particularly useful because they allow the taxpayer to provide a narrative rather than simply answering yes or no. Leading questions should generally be limited to confirming information already developed.

5. Listen more than you talk

Don't ask the next question while mentally preparing for it.

When the taxpayer finishes:

• Pause.
• Make sure you understood the answer.
• Follow up on ambiguous statements.
• Ask about unexpected information.
• Explore inconsistencies without becoming argumentative.

Useful follow-ups include:

• "Tell me more about that."
• "What happened next?"
• "Who else was involved?"
• "How was that determined?"
• "What records would show that?"
• "When did that change?"
• "Can you give me an example?"
• "What do you mean by ___?"
• "Is that based on your personal knowledge or something you were told?"

IRS guidance specifically recommends pursuing incomplete or unresponsive answers and adapting the questioning as new facts emerge.

6. Distinguish knowledge from assumptions

One of the most useful techniques is determining how the witness knows what they're telling you.

For example:

"You said the expense was entirely business-related. Were you personally involved in the transaction?" If not:

"Who would have firsthand knowledge?" This prevents an interview from becoming a chain of assumptions:

Taxpayer → representative → bookkeeper → someone else.

You want to know where the factual knowledge actually originates.

7. Reconcile testimony with documents

Don't treat either the interview or the documents in isolation.

If someone says:

"We stopped using that account in March." compare that statement with:

• bank statements,
• general ledger activity,
• deposits,
• checks,
• credit-card records,
• subsequent transactions.

If there's an apparent discrepancy, don't immediately accuse the taxpayer of being wrong. Ask:

"I may be misunderstanding something. Can you help me reconcile your statement that the account stopped being used in March with these transactions appearing in April and May?" The IRS expressly notes that information obtained through interviews should be verified through documents, reports, observations, or other appropriate examination procedures when there are concerns about accuracy.

8. Use "why/how" questions for accounting systems

For a business audit, don't limit yourself to individual line items. Understand the system that generated the return.

Explore:

• Who receives the money?
• Where is it deposited?
• Who records it?
• What software is used?
• Who has access?
• Who reconciles the bank accounts?
• How are cash transactions handled?
• How are returns/refunds recorded?
• Who approves expenses?
• How are payroll and owner payments handled?
• What happens when an error is discovered?
• Have accounting methods or personnel changed?

Understanding the system can reveal whether a questionable item is an isolated error or part of a broader problem. IRS guidance specifically identifies financial history, business operations, books and records, accounting methods, and internal controls as important interview subjects.

9. Don't argue during fact development

If you think the taxpayer's explanation is incorrect, resist the temptation to say:

"That's not possible." Instead:

"Help me understand how that occurred." Then obtain the facts and test them.

Your goal during the interview is fact development, not winning an argument. Conclusions can be reached after you've assembled and evaluated the evidence.

10. Close the loop

Before ending, summarize the important facts:

"Let me make sure I have this correctly..." Then identify:

• What was established.
• What remains unclear.
• What documents are still needed.
• Who will provide them.
• Any additional people who may have firsthand knowledge.
• What the next step will be.

You should also ask:

"Is there anything about this issue that we haven't discussed that you think I should know?" That final question can produce information you wouldn't otherwise obtain.

11. Document immediately afterward

Good interview notes should allow someone else reviewing the case to understand what was asked, what was answered, what evidence was identified, and what remains unresolved.

Record:

• Date, time, and location.
• Everyone present.
• Topics discussed.
• Significant answers.
• Important admissions or explanations.
• Documents identified.
• Follow-up items.
• Areas requiring corroboration.
• Any unresolved inconsistencies.

The IRS recommends preparing a memorandum of interview promptly and recording the taxpayer's statements accurately rather than interpreting or embellishing them.

A useful interview framework

You can structure most audit interviews around this sequence:

1. Establish — Who, what, when, where? 2. Understand — "Walk me through what happened." 3. Clarify — What exactly does that mean? 4. Attribute — How do you know? Who has firsthand knowledge? 5. Corroborate — What records support it? 6. Reconcile — Does it agree with the books, return, and third-party information? 7. Test — What would we expect to see if this explanation is correct? 8. Resolve — What remains outstanding? 9. Document — Capture the facts and follow-up items.

The biggest mistake is treating the interview as an interrogation. The strongest audit interview feels conversational to the taxpayer but is highly structured from the examiner's perspective: broad questions uncover the story, follow-ups establish precise facts, and documents independently test those facts.

• What was established.
• What remains unclear.
• What documents are still needed.
• Who will provide them.
• Any additional people who may have firsthand knowledge.
• What the next step will be.

You should also ask:

"Is there anything about this issue that we haven't discussed that you think I should know?" That final question can produce information you wouldn't otherwise obtain.

• Important admissions or explanations.
• Documents identified.
• Follow-up items.
• Areas requiring corroboration.
• Any unresolved inconsistencies.

The IRS recommends preparing a memorandum of interview promptly and recording the taxpayer's statements accurately rather than interpreting or embellishing them.

A useful interview framework

You can structure most audit interviews around this sequence:

If you mean conducting an IRS-style tax examination interview, the most effective approach is to treat the interview as a fact-finding exercise, not an interrogation. IRS guidance emphasizes planning, rapport, open-ended questions, active listening, follow-up, and thorough documentation.

1. Prepare before the interview

Know why you are interviewing the taxpayer and what facts you need that the records alone cannot establish.

Before the meeting:

• Review the return, prior-year returns, workpapers, correspondence, and documents already provided.
• Identify unusual, large, inconsistent, or potentially unsupported items.
• Separate facts that are already documented from facts that need clarification and facts that must be developed through testimony.
• Develop an interview outline tailored to the taxpayer and the issues—rather than using a generic questionnaire.
• Identify the key documents you may want to discuss during the interview.
• Decide what you need to establish before moving to the next issue.

IRS examination guidance specifically recommends reviewing available information beforehand and preparing an outline containing the interview's purpose, topics, taxpayer/witness identification, and pertinent documents.

2. Establish rapport and explain the process

Start professionally and calmly. An audit can be stressful for a taxpayer, so explain:

• Who you are and your role.
• Who is present and their roles.
• The purpose and general scope of the examination.
• How you intend to conduct the interview.
• What records or information you expect to discuss.
• How the taxpayer can ask questions or request clarification.

The goal isn't to make the taxpayer "comfortable enough to agree with you"; it's to create an environment where they will provide complete and accurate information. IRS guidance expressly emphasizes being friendly, professional, objective, honest, and calm.

3. Start broad, then narrow

A good sequence is:

Background → operations → accounting/records → specific audit issues → discrepancies → supporting evidence.

For example, rather than beginning with:

"Why did you deduct $42,000 of vehicle expenses?" start with:

"Tell me how you use the vehicles in your business." Then drill down:

• Who drives the vehicles?
• What types of trips are business-related?
• How do you determine whether a trip is business or personal?
• What records do you maintain?
• Who maintains those records?
• How are the amounts ultimately reported on the return?
• What documentation supports the amount claimed?

This gives you the taxpayer's process and factual framework before confronting a particular number.

4. Prefer open-ended questions

Open-ended questions are particularly valuable because they make the taxpayer explain the facts rather than simply confirm your assumptions. IRS guidance recommends narrative questions and limiting leading questions except when seeking confirmation.

Good:

• "Walk me through how you arrived at that amount."
• "Describe what happened."
• "How did you determine that?"
• "Who was involved?"
• "What records were created?"
• "What happened next?"

Less useful as an opening:

• "You didn't keep a mileage log, correct?"
• "That was a personal expense, wasn't it?"
• "Your accountant made that decision, right?"

Use a leading question after you've developed the facts, when you're trying to confirm something specific.

5. Listen more than you talk

One of the biggest interviewing mistakes is thinking about the next question instead of listening to the current answer.

When the taxpayer gives an unexpected answer:

Don't immediately challenge it. Explore it.

For example:

"You mentioned that the payment was for business purposes. Tell me more about what the payment was for." Then:

"Who received the payment?" Then:

"What did you receive in return?" Then:

"What documentation was created?" This progression can reveal facts that a confrontational question might never uncover.

IRS guidance recommends allowing the taxpayer to finish, pausing after answers, clarifying unclear statements, and following up on incomplete or vague responses.

6. Follow every material lead

If an answer is vague, don't simply record it and move on.

For example:

Taxpayer: "My bookkeeper handled all of that."

Follow with:

• "What exactly did the bookkeeper handle?"
• "What information did you provide to the bookkeeper?"
• "Who decided which expenses were deductible?"
• "Did you review the records before the return was filed?"
• "What did you review?"
• "When did you review them?"
• "Are there records showing that review?"

The important distinction is between "I don't know" and "I don't know because someone else handled it." The latter can lead you to another knowledgeable witness or additional records.

7. Interview the representative intelligently

A representative can be extremely useful—but don't assume the representative has firsthand knowledge of every fact.

Determine early:

"Which aspects of the taxpayer's operations and records are you personally familiar with?" Then distinguish among:

• Facts the representative personally knows.
• Information obtained from the taxpayer.
• Information obtained from the books and records.
• Professional opinions or tax positions.

IRS guidance recognizes that a representative may be interviewed when the representative has firsthand knowledge, while also providing specific rules concerning when the taxpayer can be required to participate.

If the representative says, "The taxpayer told me that," that's potentially quite different from:

"I personally observed that." That distinction should be captured in your notes.

8. Use documents to test the story

The interview shouldn't exist separately from the examination of records.

If the taxpayer says:

"We always recorded cash receipts." follow with:

"Show me where those receipts are recorded." If they say:

"That expense was entirely business." ask:

"What documentation supports the business purpose?" If the testimony and records conflict, don't necessarily accuse the taxpayer of being wrong. Instead:

"Help me reconcile what you've described with this record." That approach is both more professional and often more productive.

IRS guidance specifically cautions that information obtained through interviews should be verified through documents, reports, observations, or other appropriate examination procedures when circumstances warrant.

9. Don't argue tax law prematurely

A useful interview generally establishes facts first and conclusions second.

Instead of:

"That's not deductible under §162." try:

"Tell me the business purpose of the expenditure." Then establish:

• What was purchased?
• Who purchased it?
• When?
• From whom?
• Why?
• How was it paid?
• Who benefited?
• How was it recorded?
• What documentation exists?

Once the facts are established, you can analyze the applicable tax law.

This helps prevent the interview from becoming an argument over conclusions when the underlying facts haven't been fully developed.

10. Close each issue before moving on

Before leaving an important topic, ask yourself:

Do I know who, what, when, where, why, how, amount, and supporting evidence?

A useful closing question is:

"Is there anything else about this transaction or expense that you think I should understand?" Then pause.

Taxpayers sometimes provide the most useful information after they believe the questioning is finished.

11. Document the interview immediately

Your notes should capture facts and significant statements, not merely your impressions.

Afterward, document:

• Who attended.
• Date and location/method.
• Topics covered.
• Significant questions and answers.
• Documents identified or discussed.
• Explanations of unusual items.
• Admissions or important factual assertions.
• Leads requiring further investigation.
• Outstanding questions.
• Any inconsistencies that need reconciliation.

IRS examination guidance recommends preparing a memorandum of interview shortly after the meeting and documenting enough detail that the examination record contains a clear understanding of the taxpayer's financial history, operations, records, and unresolved questions.

A practical interview framework

You can use this simple structure:

1. Opening

• Introductions
• Purpose and scope
• Participants and roles

2. Taxpayer background

• Personal/business history
• Changes during the year
• Sources of income

3. Business/financial operations

• How the business actually operates
• Personnel and responsibilities
• Banking and payment processes

4. Books and records

• What records exist
• Who creates them
• Who maintains them
• Accounting system and controls

5. Issue-specific questions

• Start broad
• Establish facts
• Drill down
• Reconcile with documents

6. Follow-up

• Resolve vague or incomplete answers
• Identify additional witnesses/documents
• Pursue significant leads

7. Closing

• Summarize your understanding
• Identify outstanding information
• Ask whether anything important was omitted
• Explain next steps

The central principle is: prepare thoroughly, ask neutrally, listen carefully, follow the facts, verify important assertions, and document what you learned. That is much more effective than trying to "catch" the taxpayer in a contradiction.

For an IRS examiner, the irs.gov is particularly useful because it provides detailed procedures on planning, questioning, representatives, listening, and documentation.

Then pause.

Taxpayers sometimes provide the most useful information after they believe the questioning is finished.

Instead of:

To effectively conduct an audit interview, you must focus on thorough preparation, structured questioning, and precise documentation.

Here is a step-by-step guide to managing the interview professionally and gathering accurate data.

📋 Pre-Interview Preparation

• Analyze returns: Review the taxpayer's past tax filings, financial statements, and third-party data.
• Identify risks: Pinpoint specific areas of potential non-compliance or unusual fluctuations.
• Define goals: List the exact information and missing documents you need to secure.
• Draft an agenda: Outline the meeting structure to keep the discussion on track.

🤝 Establishing Control and Rapport

• Verify authority: Check the representative’s Power of Attorney (e.g., Form 2848 in the US) immediately.
• Explain process: State the purpose of the audit, the interview flow, and taxpayer rights.
• Set the tone: Maintain a professional, neutral, and non-accusatory demeanor to reduce defensiveness.

🗣️ Effective Questioning Techniques

• Use open questions: Start with "how," "why," or "describe" to encourage detailed explanations.
• Pivot to closed questions: Use "yes" or "no" queries only to confirm specific facts.
• Ask about internal controls: Understand who handles cash, invoicing, and bookkeeping.
• Inquire about lifestyle: Ask about personal expenses to spot gaps between reported income and living standards.
• Listen actively: Allow for silence; do not interrupt when the interviewee is speaking.

📝 Managing the Representative

• Interview the taxpayer: Request the taxpayer's presence if the representative lacks direct knowledge of daily operations.
• Limit deflections: Politely steer the conversation back to the question if the representative redirects.
• Set deadlines: Grant reasonable time if they need to research an answer, but document the deadline.

📑 Documentation and Wrap-Up

• Take detailed notes: Record dates, specific responses, and behavioral observations accurately.
• Review testimony: Read your summary back to the interviewee to confirm accuracy on the spot.
• Issue an Information Document Request (IDR): Formalize the list of records requested during the meeting.

To help me tailor advice for your upcoming meeting, tell me:

• What type of taxpayer are you auditing? (Individual, small business, or large corporation?)
• Are there specific red flags you are investigating? (Unreported income, high deductions, cash transactions?)
• Will you be speaking to the taxpayer directly or only their representative?

If you mean an IRS tax examination interview, the most effective approach is to treat the interview as a structured fact-finding exercise—not as an interrogation. IRS guidance emphasizes preparation, open-ended questioning, careful listening, appropriate follow-up, and thorough documentation.

1. Prepare before the interview

Start by identifying exactly what you need to learn from the interview.

• Review the return, prior-year returns, information already provided, third-party information, and the audit issues.
• Separate information into: - facts already established by documents,
• facts requiring clarification, and
• facts that can only reasonably be developed through testimony.
• Develop an interview outline organized by topic rather than a rigid script.
• Identify unusual, large, inconsistent, or questionable items that need explanation.
• Know what documents you will want to discuss during the interview.

The IRS specifically recommends tailoring questions to the taxpayer and examination issues and being prepared to modify the outline as new information emerges.

2. Establish rapport and explain the process

Begin professionally and calmly. A taxpayer may be nervous simply because an audit is an unusual experience.

A good opening might be:

"Thank you for meeting with me. I'd like to first understand your business and recordkeeping practices, and then we'll discuss the specific items under examination. I'll ask questions about how the transactions occurred and may ask follow-up questions when something needs clarification." Explain the purpose and general process of the examination and address applicable taxpayer rights and representation issues. IRS procedures call for discussing rights and the examination process during the initial interview.

3. Start broad, then become specific

Avoid beginning with accusatory or highly technical questions. First establish the big picture.

For a business, for example:

1. "Tell me about the business and what it does."
2. "Who is involved in the day-to-day operations?"
3. "Walk me through how a typical sale occurs, from the customer placing the order through recording the revenue."
4. "How are expenses initiated, approved, paid, and recorded?"
5. "What books and records do you maintain?"
6. "Who maintains them, and what software or systems are used?"

Then drill down into particular audit issues.

This approach helps you understand the taxpayer's actual processes before testing whether the reported tax results are consistent with those processes.

4. Favor open-ended questions

Open-ended questions generally produce much more useful information than questions that invite a simple "yes" or "no."

Less effective:

"You didn't maintain a mileage log, correct?" Better:

"How did you track the business mileage claimed on the return?" Then follow up:

"Who recorded it?" "When was it recorded?" "What information was used?" "Where are those records now?" "How did you determine the business versus personal portion?" IRS examination guidance specifically recommends open-ended questions and limiting leading questions primarily to situations where confirmation is appropriate.

5. Listen more than you talk

One of the biggest interviewing mistakes is thinking about the next question instead of listening to the current answer.

When the taxpayer gives an unexpected answer:

• Don't immediately challenge it.
• Pause.
• Clarify the terminology.
• Ask the taxpayer to explain the process in their own words.
• Explore inconsistencies without signaling your conclusion prematurely.

For example:

"You mentioned that the payment wasn't business income. Help me understand what the payment represented." If the answer is vague:

"What happened next?" or:

"Who was involved in that transaction?" or:

"What records would allow us to verify that?" IRS guidance emphasizes patience, listening, paraphrasing unclear answers, allowing pauses, and pursuing incomplete responses.

6. Interview the representative appropriately

A representative can be extremely useful, but you need to establish what the representative actually knows firsthand.

Ask questions such as:

• "What was your role in maintaining these records?"
• "Did you personally participate in the transactions?"
• "Who made the underlying business decisions?"
• "Who prepared the books?"
• "Who supplied the information used to prepare the return?"
• "What did you personally observe?"

If the representative prepared the return but lacks firsthand knowledge of the taxpayer's business operations, distinguish between what the representative knows and what was simply reported to the representative.

IRS guidance recognizes that a representative may be interviewed without the taxpayer present when the representative has firsthand knowledge, while IRC §7521(c) generally prevents an examiner from requiring a represented taxpayer to accompany the representative absent an administrative summons.

7. Test explanations against the records

Don't simply ask, "Is this correct?"

Instead, reconstruct the transaction.

For example, for a questionable expense:

"What was purchased?" "Who purchased it?" "When?" "From whom?" "How was it paid?" "What was the business purpose?" "Where was it recorded?" "What documentation was created at the time?" "Who has custody of that documentation?" You're trying to establish who, what, when, where, why, and how, and then determine whether the documentary evidence supports the testimony.

8. Follow leads—but don't lose control of the interview

A good interview isn't a checklist.

If an answer reveals a potentially important fact, pursue it even if it wasn't on your original outline. Conversely, don't spend excessive time on irrelevant subjects simply because they are interesting.

IRS guidance specifically says the outline should be flexible and that the examiner should develop new facts as they arise.

A useful mental model is:

Question → Listen → Clarify → Follow the lead → Tie back to the audit issue.

9. Deal with inconsistencies neutrally

If testimony conflicts with a document, avoid immediately saying, "That's not true."

Try:

"Earlier you indicated X. This document appears to show Y. Help me reconcile those two." This gives the taxpayer an opportunity to explain the discrepancy and can reveal whether the issue is a misunderstanding, bookkeeping error, timing difference, or something more significant.

10. Close each issue before moving on

Before changing subjects, make sure you know:

• What happened?
• Who was responsible?
• When did it happen?
• How was it recorded?
• What documentation exists?
• Does the taxpayer's explanation resolve the issue?
• What additional information is needed?

You don't necessarily need to resolve the tax treatment during the interview. Your objective is to establish the facts and evidence needed to make that determination.

11. Document the interview immediately afterward

Your notes should allow someone reviewing the case later to understand the taxpayer's financial history, business operations, records, significant items, explanations, and unresolved questions.

IRS guidance recommends brief notes during the interview followed by a memorandum of interview or appropriate questionnaire documentation shortly afterward.

A strong interview memorandum should distinguish between:

• what the taxpayer/representative said,
• what documents establish,
• your observations, and
• what remains unresolved.

Don't rely on memory several days later.

A practical interview framework

For most audits, this sequence works well:

1. Opening → Introductions, purpose, process, rights/representation

2. Background → Taxpayer, business, occupation, ownership, history

3. Operations → How money is earned, spent, recorded, and controlled

4. Books and records → Who maintains them, systems used, source documents, reconciliation

5. Audit issues → Work through each issue systematically

6. Follow-up → Resolve vague, incomplete, or inconsistent answers

7. Documents → Identify evidence supporting or contradicting testimony

8. Summary → Confirm important facts and outstanding information

9. Next steps → Explain what additional documentation or information is needed

The key principle is: prepare thoroughly, ask neutrally, listen carefully, follow the facts, and document what you learn. That combination is much more effective than trying to "catch" the taxpayer in a contradiction.

For the official procedural framework, the IRS's IRM 4.10.3, Examination Techniques is particularly useful; it contains detailed guidance on preparation, interview techniques, representatives, listening, and documentation.

• What happened?
• Who was responsible?
• When did it happen?
• How was it recorded?
• What documentation exists?
• Does the taxpayer's explanation resolve the issue?
• What additional information is needed?

You don't necessarily need to resolve the tax treatment during the interview. Your objective is to establish the facts and evidence needed to make that determination.

A practical interview framework

For most audits, this sequence works well:

1. Opening → Introductions, purpose, process, rights/representation

To effectively conduct an audit interview, you must balance rigorous data collection with professional, objective communication. The primary goal is to gather facts, understand the taxpayer's accounting system, and evaluate internal controls.

1. Preparation and Planning

• Review files: Study tax returns, prior audit history, and third-party documentation beforehand.
• Define objectives: Identify specific risk areas, missing data, or unusual items requiring explanation.
• Draft agenda: List key topics to keep the conversation structured and efficient.
• Set environment: Choose a neutral, professional, and quiet setting to minimize distractions.

2. Opening the Interview

• State purpose: Explain the scope of the audit and the specific goals of the meeting.
• Establish ground rules: Outline how information will be recorded and timelines for follow-up requests.
• Observe representation: Verify power of attorney documents if a representative is speaking for the taxpayer.
• Build rapport: Maintain a polite, professional, and non-adversational tone to encourage open communication.

3. Effective Questioning Techniques

• Use open questions: Start with "how," "why," or "describe" to encourage detailed explanations.
• Pivot to closed questions: Use precise questions to confirm specific figures, dates, or facts.
• Listen actively: Allow the speaker to finish without interruption before taking detailed notes.
• Test consistency: Cross-check verbal answers against the physical books and financial records provided.

4. Managing the Dynamics

• Address evasiveness: Note instances where a subject avoids questions, and gently return to the topic.
• Control the pace: Do not let a representative monopolize the time or steer the conversation away from the facts.
• Maintain neutrality: Remain calm, factual, and objective, even if the taxpayer becomes defensive.
• Document everything: Take contemporaneous notes of admissions, explanations, and refusals to answer.

5. Closing and Follow-Up

• Summarize findings: Recapitulate the key points discussed to ensure mutual understanding.
• List missing items: Provide a clear, written Document Request List for any outstanding items.
• Set deadlines: Agree on firm, reasonable dates for the submission of additional evidence.
• Outline next steps: Explain the subsequent phases of the audit process and when they will hear from you next.

To tailor this strategy further, tell me:

• What type of taxpayer are you auditing? (Individual, small business, or large corporation?)
• What specific tax issue or industry is under review?
• Are you dealing directly with the taxpayer or a hired power of attorney?

I can help you draft specific interview questions or checklist items for your meeting.

If you mean an IRS-style civil tax audit interview, the most effective approach is to treat the interview as a structured fact-finding exercise, not an interrogation. IRS guidance emphasizes preparation, clear and objective questions, active listening, and following up on vague or inconsistent answers.

1. Prepare before the interview

Know exactly why you are interviewing the taxpayer.

Before the meeting:

• Review the return, workpapers, prior-year returns, third-party information, and documents already provided.
• Identify the specific audit issues and the facts you need to establish for each one.
• Develop a question outline rather than improvising.
• Identify discrepancies or unusual items that require explanation.
• Determine who has firsthand knowledge of the business, finances, bookkeeping, and transactions.
• Organize the documents so you can move quickly from an answer to the supporting evidence.

The IRS specifically recommends tailoring the interview to the taxpayer and issues, researching questionable items beforehand, and planning the questions.

2. Establish rapport and explain the process

Start calmly and professionally. A nervous taxpayer may provide incomplete or poorly organized answers simply because they don't understand what is happening.

A good opening is essentially:

"I'd like to begin by understanding your business and financial activities, and then we'll discuss the specific items under examination. I'll ask some questions first, and we'll use the records to clarify the answers." IRS examination guidance recommends introducing yourself, explaining what will happen, maintaining a friendly and professional demeanor, and recognizing that an audit may be an unusual and stressful experience for the taxpayer.

Also make sure representation and procedural rights are handled correctly. An authorized representative can generally represent the taxpayer at an interview, and the taxpayer ordinarily cannot be required to accompany that representative absent an administrative summons.

3. Start broad, then narrow

One of the biggest interviewing mistakes is beginning with a highly specific question such as:

"Why did you deduct $42,000 of automobile expenses?" Instead, establish the overall picture first:

• "Tell me about your business and what you do."
• "Walk me through a typical week."
• "How do customers pay you?"
• "How are sales recorded?"
• "Who handles the bookkeeping?"
• "What bank accounts does the business use?"
• "How are business expenses paid and documented?"

Then move toward the particular issue.

This gives you context and can reveal facts the taxpayer might never mention if you immediately focus on the disputed deduction. IRS guidance specifically favors open-ended questions and recommends being receptive to information volunteered by the taxpayer.

4. Use a funnel-questioning technique

A useful sequence is:

Open question → clarification → specifics → documentation → reconciliation

For example:

Open: "Tell me how you calculated the business mileage deduction."

Clarify: "What records did you use?"

Specific: "Who recorded the mileage?"

Documentation: "Do you have the contemporaneous mileage log?"

Reconcile: "The log shows 18,000 business miles, but the return reflects 27,000. Help me understand the difference."

This approach is much more effective than repeatedly asking "Why?" because it lets the taxpayer explain the facts before you test them.

5. Listen more than you talk

Pay particular attention to:

• Vague answers
• Changes in terminology
• Answers that don't address the question
• Internal inconsistencies
• Differences between the interview and the records
• Statements indicating additional accounts, transactions, or sources of funds
• "My accountant handled that" answers
• Information volunteered that affects another audit issue

Don't immediately confront an inconsistency. First make sure you understood the answer.

For example:

"Let me make sure I understand. You said the account was used exclusively for business, but the records show several personal payments. Can you walk me through those transactions?" IRS guidance specifically instructs examiners to listen carefully and pursue responses that are inconsistent, vague, or incomplete.

6. Be careful when interviewing a representative

A representative is useful only to the extent that they actually know the facts.

Determine early:

"Which aspects of the taxpayer's operations do you have firsthand knowledge of?" If the representative prepared the return but doesn't know the day-to-day operations, distinguish between:

• What the representative knows firsthand
• What the taxpayer told the representative
• What the records establish
• What is simply an assumption

IRS guidance specifically allows an examiner to interview a representative without the taxpayer present when the representative has firsthand knowledge of the business, bookkeeping, accounting practices, and daily operations.

Don't let the interview become entirely theoretical. If the representative says, "That's how the client told us it worked," you may need to establish the underlying facts directly.

7. Don't argue with the taxpayer

Your objective is to establish facts—not win an argument.

Instead of:

"That doesn't make sense." Use:

"Help me understand how those two pieces of information fit together." Instead of:

"That's not deductible." Use:

"Let's separate the factual question from the tax treatment. First, let's establish what the payment was for, who paid it, and how it was documented." This keeps the interview objective and makes the resulting workpapers much stronger.

8. Ask the "who, what, when, where, how, and why"

For significant transactions, systematically establish:

• Who was involved?
• What happened?
• When did it happen?
• Where did it happen?
• How was it paid or recorded?
• Why did it occur?
• What records support it?
• Who else can verify it?

IRS interview guidance similarly emphasizes these basic factual questions and obtaining the factual basis for answers.

9. Close each issue before moving on

Before changing subjects, summarize:

"So, as I understand it, the $15,000 payment was made to ABC on March 12, it was for equipment, it was paid from the business account, and you have the invoice and canceled check. Is that accurate?" This gives the taxpayer an opportunity to correct your understanding and creates a much clearer evidentiary record.

10. End with a controlled summary

At the end, summarize:

• What you understand.
• What documents were provided.
• What documents are still needed.
• Which questions remain unresolved.
• What will happen next.

Don't surprise the taxpayer with an entirely new theory at the end unless the interview uncovered something genuinely new.

Interviews are intended to develop facts and evidence, and IRS procedures contemplate documenting who was interviewed and the issues discussed.

A practical interview framework

You can use this as a one-page checklist:

1. Purpose — What issues am I trying to resolve?
2. Authority/participants — Who is present and what is their role?
3. Background — What does the taxpayer's financial/business operation look like?
4. Records — What books, accounts, systems, and source documents exist?
5. Issue-by-issue questioning — What happened?
6. Follow-up — Does the answer reconcile with the records?
7. Expand — Does the answer suggest another source, account, transaction, or issue?
8. Confirm — Can the taxpayer substantiate the answer?
9. Summarize — What facts have been established?
10. Document — What remains outstanding and what is the next step?

The key mindset is: be curious, not adversarial; ask open questions first; listen carefully; verify with records; and document the facts rather than arguing conclusions.

For an IRS examiner, the current Internal Revenue Manual, especially IRM 4.10.3 (Examination Techniques), is the best detailed procedural reference.

If you're conducting these interviews as a tax auditor/examiner, I can also give you a professional 30–45 minute audit interview script with exact questions for the opening, business background, income, expenses, bank accounts, representative, and closing.

Don't surprise the taxpayer with an entirely new theory at the end unless the interview uncovered something genuinely new.

This keeps the interview objective and makes the resulting workpapers much stronger.

8. Ask the "who, what, when, where, how, and why"

For significant transactions, systematically establish:

• Who was involved?
• What happened?
• When did it happen?
• Where did it happen?
• How was it paid or recorded?
• Why did it occur?
• What records support it?
• Who else can verify it?

IRS interview guidance similarly emphasizes these basic factual questions and obtaining the factual basis for answers.

If you mean an IRS examination/audit interview, the most effective approach is to treat the interview as a fact-finding exercise, not an interrogation. Current IRS examination guidance emphasizes preparation, open-ended questions, careful listening, professional rapport, and thorough documentation.

1. Prepare before the interview

Review the return, prior-year returns, available third-party information, the case file, and documents already received. Identify:

• The specific issues you need to resolve.
• Large, unusual, or questionable items.
• Gaps or inconsistencies in the records.
• Questions that can only be answered by the taxpayer or someone familiar with the business.
• What you already know versus what you need to establish.

Prepare an issue-based question outline, but don't turn it into a script. IRS guidance specifically recommends preparing questions in advance while remaining flexible enough to pursue information that emerges during the interview.

2. Establish the ground rules

At the beginning:

1. Introduce yourself and everyone attending.
2. Confirm who is representing the taxpayer and the scope of the representative's authorization.
3. Explain the purpose and general process of the examination.
4. Make sure the taxpayer has received the applicable taxpayer-rights information.
5. Identify who has firsthand knowledge of the taxpayer's operations and records.
6. Explain what you hope to accomplish during the interview.

A taxpayer generally may act personally or have an authorized representative, and IRS guidance addresses the taxpayer's right to consult with a representative during an examination.

3. Start broad, then narrow

A good sequence is:

Broad → operational → financial → specific issue → corroboration.

For example, instead of immediately asking:

"Why did you deduct $48,000 of consulting expenses?" start with:

• "Please describe the business and how it operated during the year."
• "Walk me through how you generated revenue."
• "How did you acquire and pay vendors?"
• "Who was responsible for approving expenses?"
• "How were those transactions recorded?"
• "Tell me about the consulting services you used during the year."

Then drill down into the $48,000.

Open-ended questions are particularly useful because they encourage the interviewee to explain the facts rather than simply confirm the proposition contained in your question. IRS examination guidance expressly recommends clear, relevant, objective, open-ended questions.

4. Follow the answer, not just your outline

One of the biggest interviewing mistakes is asking the next prepared question without investigating an unexpected answer.

Listen for:

• Inconsistencies with the return.
• Changes in accounting procedures.
• Unreported sources of funds.
• Transactions involving related parties.
• Cash transactions.
• Missing records.
• Vague descriptions of services.
• Statements that conflict with documents.
• People or accounts you weren't previously aware of.

When something doesn't make sense, don't immediately accuse the taxpayer of being wrong. Ask:

"Help me understand how those two things fit together." or:

"Earlier you said X. The records appear to show Y. Can you walk me through the difference?" The IRS specifically instructs examiners to pursue responses that are inconsistent, vague, or incomplete.

5. Interview the representative intelligently

A representative can be extremely helpful, but distinguish between knowledge of the tax position and firsthand knowledge of the underlying facts.

Ask the representative:

"Is that based on your understanding of the records, or were you personally involved in the transaction?" For factual questions, identify the person who actually knows the answer—for example, the owner, bookkeeper, controller, salesperson, or person who negotiated the transaction.

IRS guidance recognizes that an authorized representative may not necessarily have sufficient firsthand knowledge of the taxpayer's operations and circumstances.

At the same time, remain professional. The objective is to establish facts, not to "beat" the representative.

6. Use the "who, what, when, where, why, and how" framework

For a questionable transaction, systematically establish:

• Who was involved?
• What happened?
• When did it happen?
• Where did it happen?
• Why did it happen?
• How was it paid, recorded, documented, and reported?

Then ask the crucial corroboration question:

"What records would allow us to verify that?" This turns a conversational answer into an auditable fact pattern.

7. Don't argue tax law prematurely

If the taxpayer says:

"That expense is deductible because it was for the business." Don't immediately debate the deduction.

First establish the facts:

• What was purchased?
• Who provided it?
• What business purpose did it serve?
• When was it incurred?
• How was it paid?
• How was it recorded?
• What documentation exists?
• Who benefited?
• Was there any personal component?

Once the facts are established, you can analyze the applicable tax law.

8. Watch for the difference between an explanation and evidence

A plausible explanation isn't necessarily proof.

For example:

"Those deposits were loans from family members." Follow with:

• Who made each loan?
• When?
• How much?
• What were the repayment terms?
• How was the money transferred?
• Was there a written agreement?
• Were repayments made?
• Where is the transaction reflected in the books?
• What documentation corroborates it?

This approach is much stronger than simply accepting or rejecting the taxpayer's explanation.

9. Maintain rapport

A productive audit interview should feel professional and controlled, rather than adversarial.

The IRS's examination guidance recommends being friendly and professional, remaining calm and objective, listening carefully, and considering the taxpayer's perspective.

Useful phrases include:

• "I want to make sure I understand this correctly."
• "Let's go back to that point."
• "Can you walk me through that?"
• "What happened next?"
• "Who would have the records showing that?"
• "Is there anything else about that transaction I should understand?"
• "What would be the best document for me to review to verify that?"

These encourage disclosure without unnecessarily putting the interviewee on the defensive.

10. Close the loop on every issue

Before moving away from an issue, determine:

Fact → explanation → evidence → unresolved question.

For example:

"So, as I understand it, the $75,000 payment was made to ABC, it was for consulting services performed between March and December, and you have invoices and the engagement agreement. Is that accurate?" Then identify what remains outstanding.

This prevents misunderstandings and makes your workpapers much stronger.

11. Document the interview immediately

Don't rely on memory.

Your documentation should identify the date, location, participants, subjects discussed, important statements, documents referenced, and conclusions or unresolved matters. IRS guidance recognizes several methods, including informal notes, a memorandum of interview, question-and-answer format, affidavit, and other formal methods depending on the circumstances.

When possible, distinguish clearly between:

• What you observed.
• What the taxpayer said.
• What the representative said.
• What the records show.
• Your examination conclusion.

Avoid silently converting an interviewee's statement into your interpretation of what they "must have meant."

A practical interview structure

A solid 60–90 minute interview might look like:

1. 5–10 min: introductions, representation, purpose, rights/process.
2. 10–15 min: taxpayer/business history and overall operations.
3. 10–15 min: accounting system, books, records, and internal controls.
4. 20–40 min: specific audit issues, moving from broad questions to transaction-level detail.
5. 10 min: inconsistencies, missing information, and follow-up questions.
6. 5–10 min: summarize your understanding, identify outstanding documents, and explain next steps.

The key principle is: prepare extensively, ask simply, listen carefully, follow the facts, corroborate important statements, and document objectively.

If you're an IRS examiner, the current starting point is IRM 4.10.3, which was revised August 26, 2025 and contains the Service's current examination-interview guidance.

This prevents misunderstandings and makes your workpapers much stronger.
