Key Facts

Federal level: The IRS starts an audit by mail, not with an unsolicited initial telephone call.
Federal level: An audit may occur by correspondence, at an IRS office, or at a taxpayer’s home, business, or representative’s office.
Federal level: The notice identifies the return and issues under review, the records requested, and a response deadline.
Federal level: Taxpayers have rights to information, privacy, representation, challenge, and an independent appeal.
Federal level: An examination can close with no change, agreed changes, or disputed proposed changes.

Being audited by the IRS means the agency is examining a return and supporting records to verify that income, deductions, credits, and tax were reported correctly. Selection does not itself prove an error or misconduct. The examination may end with no change, a refund, or proposed additional tax, penalties, and interest.

The notice controls the immediate task. Read every page, verify the tax year and deadline, and compare the requested items with the filed return before responding.

Confirm that the contact is genuine

The IRS states that it initiates an audit by mail. An unexpected caller, text sender, or email demanding immediate payment or sensitive information should not be treated as an audit notice. Use contact details independently obtained from IRS.gov or an established IRS account rather than links or numbers supplied in a suspicious message.

A genuine letter generally identifies the taxpayer, tax form, year, issues, requested documents, response method, and deadline. Keep the original and the envelope. A notice can be authentic even when the taxpayer believes the return was correct.

Why returns are selected

IRS selection methods include computer screening against statistical norms, random research samples, and related examinations involving transactions with another selected taxpayer. Information returns and compliance projects can also identify discrepancies. An amended return or refund does not automatically trigger an audit, although amended returns are screened.

Selection is different from the eventual finding. The examiner must evaluate the return and evidence within the audit’s scope. The taxpayer should focus on substantiating the questioned items rather than guessing why the return entered the selection process.

Correspondence, office, and field audits

A correspondence audit is handled primarily by mail or an authorized electronic response channel. The letter requests support for particular items, such as income, expenses, filing status, dependents, or credits. If the volume of records is impractical to mail, the IRS says a taxpayer can request a face-to-face audit.

An office audit involves an interview at an IRS office. A field audit occurs at the taxpayer’s home, place of business, or representative’s office. In-person examinations may cover more complex records and allow the examiner to ask follow-up questions. The location does not remove the taxpayer’s rights to understand the request or obtain authorized representation.

What authority the IRS has

Internal Revenue Code section 7602 authorizes the IRS to examine relevant books, papers, records, and other data when determining the correctness of a return or tax liability. It also authorizes summonses and testimony under specified procedures. That authority is broad, but an audit request should still identify its tax purpose and the records sought.

Respond to the actual information document request. Do not alter or fabricate records, and do not send unexplained piles of documents. If a request appears unclear or overbroad, seek clarification and preserve the response deadline.

Build a documented response

The IRS records-request guidance says records should be organized by year and type of income or expense, with transaction summaries and context. Relevant material can include receipts, bills, canceled checks, bank statements, mileage records, legal papers, loan agreements, employment documents, Forms W-2 and 1099, and Schedules K-1.

Send copies, not original records. Match each exhibit to the notice item, label it consistently, and include a short factual explanation when a document does not speak for itself. Retain a complete copy of the submission and proof of delivery or upload confirmation.

If records were lost, document why and gather reliable substitutes from banks, vendors, employers, insurers, or public records. A reconstructed number needs a reasonable method and supporting evidence; an estimate without foundation may not substantiate the return.

Deadlines and requests for more time

For a mail audit, IRS guidance says a written request can ordinarily obtain one automatic 30-day extension, subject to the notice and circumstances. In an in-person audit, contact the assigned examiner and, if needed, the manager. A response after the deadline may not stop the IRS from completing the examination using available information.

A Notice of Deficiency is different. The IRS cannot extend the statutory period for petitioning the U.S. Tax Court. The notice states the deadline, commonly 90 days for a domestic address, and the petition generally must be timely filed to obtain prepayment Tax Court review.

How far back the audit can reach

Section 6501 generally allows assessment within three years after a return is filed, but the statute contains important exceptions and longer periods. IRS audit guidance says examinations ordinarily include returns filed within the last three years and may add years when a substantial error is identified; the agency usually does not go back more than six years.

No single “three-year rule” answers every case. Substantial omissions, listed transactions, missing international information, false or fraudulent returns, and failure to file can change the period. The IRS may ask the taxpayer to consent to an extension. Consent is not mandatory, but refusing can lead the examiner to make a determination based on the existing record before the period expires.

Representation and taxpayer rights

Publication 1 describes the rights to be informed, receive quality service, pay no more than the correct tax, challenge the IRS and be heard, appeal in an independent forum, finality, privacy, confidentiality, retain representation, and a fair and just tax system.

A taxpayer may act personally or authorize a qualified representative, commonly through Form 2848. Representation can be especially useful when business books, multiple years, summonses, potential penalties, criminal concerns, or an expiring assessment period are involved. An authorized representative does not eliminate the need for accurate facts and complete records.

Closing the examination

A no-change closing means the examined items were accepted. In an agreed case, the taxpayer signs the examination report or comparable agreement and addresses any balance through payment or an available collection option. Read the computation and affected years before signing.

In a disagreed case, a taxpayer can provide further support, request a manager conference, and—when the procedural requirements and remaining limitations period permit—seek review by the IRS Independent Office of Appeals. A statutory Notice of Deficiency can provide a route to Tax Court. Paying an assessed amount and seeking a refund follows a different route with separate deadlines.

Readers who receive a balance after an agreed or final assessment can review the separate overview of IRS payment-plan options. Payment arrangements do not replace the procedures for disputing an incorrect proposed assessment.
