Responding to IRS Audit Notices and Requests for Information: A Comprehensive Guide

What an IDR Actually Is

During an audit, the IRS sends Information Document Requests on Form 4564 — commonly called an IDR. Each IDR lists specific documents the auditor wants, the issues they relate to, and a response deadline. The IDR is the auditor's primary tool for building or breaking your return, and how you respond directly drives the adjustment that comes out the other side.

Read the IDR carefully before pulling any records. Auditors sometimes phrase requests broadly enough that compliance would expose unrelated issues. "All bank statements for tax year 2023" pulled across business and personal accounts may give the auditor enough information to open new issues. The proper response provides exactly what's necessary to substantiate the line item in question, organized to make the connection between document and tax return position obvious.

Timing and Format Strategy

Most IDRs have a 10-15 day response window with extensions available on written request. Request the extension in writing before the original deadline expires; auditors rarely refuse a first reasonable extension. Document your response with a cover letter listing every page provided, cross-referenced to the IDR item number. Make copies of everything you submit and keep them — the IRS regularly loses sub-files during examination.

Submit physical copies, not originals. Once originals are with the IRS they become part of the audit file and may not come back. Format matters too: organized binder with tabbed sections beats a banker's box of loose receipts every time, because it removes any room for the auditor to claim records weren't furnished or weren't legible.

If a particular IDR is overbroad or asks for information the IRS isn't entitled to (privileged attorney communications, work product), the response should object in writing rather than ignore the request. Silent non-compliance escalates to a summons under IRC § 7602, which the IRS can enforce in U.S. District Court. Written objection, by contrast, preserves your position and forces the auditor to either narrow the request or substitute alternative procedures.
