IRS Form 4564 is an Information Document Request, usually called an IDR. An examiner uses it to request records or explanations during an audit. It is a request for information, not an examination agreement or a final determination of the tax owed.
A useful response connects each requested item to accurate, organized support. Before sending records, understand the taxpayer, tax periods, issues, and response date identified in the request.

What an IDR may ask for
The IRS Form 4564 includes space for the documents requested, prior requests, the due date or appointment, and the requesting employee’s contact information. An attached list may provide most of the detail.
Depending on the examination, a request may concern bank deposits, business expenses, payroll, shareholder transactions, contracts, depreciation, or the records supporting a deduction or credit. The form number alone does not tell you how broad the audit is.
Start with a response plan
- Identify the scope. Confirm the person or entity under examination, the years involved, and the records requested. Keep the IDR with its cover letter and earlier requests.
- Calendar the response date. Use the date stated in your request. There is no single response period that applies to every Form 4564.
- Match records to the numbered items. Prepare an index showing which files respond to each item and which items need clarification or additional work.
- Reconcile the records. Understand how the figures connect to the filed return and books. Explain differences rather than leaving the examiner to infer their cause.
- Review completeness and sensitive material. Identify potentially privileged communications and obtain advice before producing them. A document does not become privileged merely because it was sent to an attorney.
- Keep the submission record. Retain the response, attachments, delivery confirmation, and any written agreement about additional time or remaining items.
What if the request is unclear or seems too broad?
Clarify what the examiner needs and why before assembling a large production. A discussion may resolve uncertainty about a date range, a category of records, or the form of an explanation. Document the clarification so both sides are working from the same request.
For example, a request for business bank statements may need to be read together with a request to explain deposits. Producing statements alone may not answer the second request. A reconciliation identifying transfers, loan proceeds, and customer receipts can make the response easier to evaluate when supported by the underlying records.
Do not silently leave out a requested category because it appears irrelevant. Raise the concern and address it through the examination process.
What if records are missing?
Identify what exists, what is missing, and what efforts can be made to obtain replacements. Banks, vendors, payroll providers, and prior preparers may hold useful records. Reconstructed schedules should identify their sources and limitations; they should not present estimates as original receipts.
Different deductions have different substantiation requirements. A bank payment may establish that money changed hands without proving its business purpose. The IRS recordkeeping guidance explains why supporting documentation matters.
Can you ask for more time?
If the response cannot be completed by the stated date, contact the examiner before the deadline to explain what is needed and request an extension. Confirm whether it has been granted. A request for more time is not the same as approval, and examination procedures can differ by IRS division and case type.
An IDR is different from a summons. Ignoring repeated requests may lead to further enforcement steps or an examination completed on the information available. The IRS audit guidance describes how examinations and document requests fit together.
How an IDR differs from other audit documents
- Form 4564: requests records and information.
- Form 4549: reports examination changes and may include consent to assessment and collection.
- A Notice of Deficiency: can create a separate Tax Court petition deadline.
Use our IRS audit-letters guide to identify other documents in the packet. A document response should not cause you to overlook a separate notice deadline.
Schedule a $500 Tax Attorney Consultation for review of an IDR and the records available to answer it. The fee covers up to one hour of total attorney time, including review, analysis, preparation, and the telephone consultation. Document preparation and ongoing representation require a separate engagement.
General information; the appropriate response depends on the actual request and examination.
