IRS office audit: what happens at the in-person exam

What is an IRS office audit?

An IRS office audit is an examination held face to face at an IRS office, as opposed to a mail audit or a field audit at your home or business. The IRS lists three audit formats on its IRS audits page: by mail, at an IRS office, and in the field. The office examination sits in the middle: more personal than a letter, less intrusive than a visit to your premises.

Treasury regulations say the IRS picks office or field format based on how complex the return is and which format examines it most efficiently. For individuals and sole proprietors, the office used is generally the IRS office closest to where you live (26 CFR 301.7605-1).

Being selected does not mean the IRS has found an error. Publication 3498, The Examination Process, says an examination may end with no change at all or even a refund. The appointment letter names the tax year and the exact items under review, which is often a handful of deductions, business expenses or income sources rather than the whole return. For an overview of every audit type, see the IRS audit guide.

How the IRS schedules an in-person audit

The IRS sends an appointment letter by mail, and it never opens an audit with a phone call. If someone calls claiming to schedule your audit and you have no letter, treat it as a likely scam. Our guide to IRS audit letters shows how to confirm a letter is real.

Can I reschedule an office audit?

Yes. Call the examiner named on the letter as soon as you know the date will not work. The IRS audit page says to ask the assigned auditor for more time and, if needed, to contact that auditor's manager. Publication 3498 adds that when the time or place is inconvenient, the examiner will try to arrange something more suitable.

Ask early and confirm the new date in writing. Repeated postponements without a reason can push the case toward a report based only on what the IRS already has, and an examiner may ask you to extend the assessment deadline if time is running short.

What to bring to an IRS audit at the office

Bring exactly the records the appointment letter requests, organized by the items it lists, plus copies you can hand over. The IRS gives a written request for the specific documents it wants to see, so the letter is your checklist. Bringing unrelated papers can widen the conversation without helping you.

A practical way to organize: one folder per questioned item, each with a one-page summary on top. For example, if the letter questions $8,400 of vehicle expenses, the summary shows the mileage log total, the business-use percentage and the math, followed by the log itself and repair receipts. The examiner can then test your summary instead of rebuilding it.

Can someone go to the office audit for me?

Yes. Publication 3498 says a representative can handle an in-person examination with or without you present. The representative is usually an attorney, CPA, enrolled agent, enrolled actuary, or the preparer who signed the return if they meet the rules for unenrolled preparers. You authorize them on Form 2848, and spouses on a joint return file separate Forms 2848 even when they use the same person.

Your other options: go alone, go with a representative, or bring someone as a witness or for support. If you go alone and decide mid-interview that you want professional help, the IRS will suspend and reschedule the interview, unless you are there under an administrative summons. Form 8821 only lets someone receive your information; it does not let them speak for you.

Enrolled agents, CPAs and attorneys all have unlimited rights to represent you before the IRS. Our comparison of enrolled agents and CPAs covers which fits an audit, and a Low Income Taxpayer Clinic may represent you for free or a small fee if your income qualifies.

What happens during the office examination meeting

The examiner starts by confirming you received Publication 1, Your Rights as a Taxpayer, and by explaining the process, according to the IRS audit manual (IRM 4.10.3). Then the examiner goes item by item through the letter, asks how you figured each amount and reviews your records.

• Answer the question asked, briefly, and say so if you do not know.
• If a record is missing, offer to send it by a set date rather than guessing.
• Ask what the examiner still needs before you leave, and get it in writing if possible.
• You may audio record the interview with your own equipment if you make a written request at least 10 calendar days before the meeting (IRM 4.10.3.4.7.1).

Office audits of simple issues can finish in one meeting, but many need a follow-up document request. The IRS says audit length depends on the issues, how quickly records arrive and whether you agree with the findings. See how long an IRS audit takes for typical stages.

After the meeting: the three possible results

Every office examination ends as no change, agreed or unagreed. A no-change letter means the IRS accepted your return as filed; keep it with your tax records for that year.

If you agree with proposed changes, you sign the agreement form and pay. Publication 3498 says that if the total due is under $100,000 and you pay within 21 calendar days of the bill, no further interest or penalties are added; at $100,000 or more the window is 10 business days. Example: an agreed $4,800 increase paid in full within 21 days of the bill stops growing at that point, while an unpaid balance keeps accruing interest at the quarterly rate, 7% a year for October to December 2026.

If you disagree, you can ask for a meeting with the examiner's manager, then receive a 30-day letter explaining your right to go to the IRS Independent Office of Appeals. If you cannot pay the agreed amount at once, pay what you can and set up an IRS payment plan for the rest.
