What to do if…
you receive a tax audit notice and the response deadline is soon

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Act today: verify the notice is genuine, identify which tax authority sent it, then use the contact route on the notice to ask what is needed and whether extra time is available for your notice type.

Do not do these things

  • Do not ignore the date on the notice; if you do not respond, the tax authority may move forward without your information.
  • Do not assume a call, email, text, or letter is genuine just because it names the IRS or another tax agency; verify through official information before sharing personal details.
  • Do not send original records unless the notice specifically asks for them; keep originals and send copies where allowed.
  • Do not sign an agreement to proposed changes if you do not understand what it means.
  • Do not send a large bundle of unrelated documents; focus on the items the notice asks about.
  • Do not file an amended return in a panic unless you understand how it affects this audit or have advice.

What to do now

  1. Capture the key facts from the notice.
    Write down the agency name, notice or letter number, tax year, response date, items being questioned, contact details, and whether the notice mentions an examination, audit, proposed changes, or a notice of deficiency.

  2. Verify that the notice is genuine before you respond.
    For an IRS notice, check the notice or letter number against official IRS notice information. For IRS audits, the IRS says it will notify you by mail and will not initiate an audit by telephone. If the notice says it is from a state tax agency, use that agency’s official website and the notice instructions to verify the contact route before you send documents, money, or personal information.

  3. Use the notice’s contact route before the deadline.
    Call, fax, mail, upload, or contact the assigned auditor exactly as the notice instructs. Ask what specific records they need, which tax return lines or issues they relate to, and how they want the response sent. Write down the date, time, number used, and the name or ID of anyone you speak to if they provide one.

  4. Ask about extra time if you cannot respond in full.
    Ask whether this notice type allows more time and how to request it. For an IRS mail audit, the IRS may ordinarily grant a one-time automatic 30-day extension if requested properly, but some deadlines cannot be extended. If the letter says “Notice of Deficiency” or mentions a 90-day Tax Court petition deadline, do not assume the IRS can extend it.

  5. Build a focused response packet.
    Make a simple cover sheet with your name, notice or letter number, tax year, and the identifying information the notice asks for. Add a short index: “Issue 1 → documents A and B,” “Issue 2 → documents C and D.” Answer the questions on the notice directly.

  6. Send the response in a way you can prove.
    If mailing, use a trackable service and keep the receipt, delivery confirmation, and a full copy of everything sent. If faxing or uploading, save the confirmation page or upload receipt and keep copies of the files.

  7. Get representation if you need it, but do not delay the deadline step.
    For an IRS matter, if you want a qualified person to speak to the IRS for you, ask about using Form 2848, Power of Attorney and Declaration of Representative. If the deadline is close, still contact the IRS, state agency, or assigned auditor today to ask about time while you arrange help.

  8. Pause before agreeing to proposed changes.
    The IRS publishes taxpayer rights in Publication 1, including rights to know why information is being requested, to representation, and to appeal many disagreements. If you disagree or are unsure, focus first on preserving the response deadline and asking what the next dispute step is.

What can wait

  • You do not need to reconstruct your entire tax history tonight; start with the tax year and items named in the notice.
  • You do not need to decide today whether to fight every issue; first, prevent the audit from moving forward without your input.
  • You do not need to contact unrelated agencies; keep communication focused on the specific notice and the contact route it gives.
  • You do not need a perfect packet before asking for more time; the extension request itself may be the urgent task.

Important reassurance

An audit notice is frightening, but it is usually a structured process with written instructions. The safest immediate move is to verify the notice, communicate before the deadline, send an organized response, and keep proof of everything.

Scope note

These are first steps for the moment you realize the response deadline is near. Later decisions, especially for large amounts, business records, multiple years, penalties, a state tax notice, or a notice of deficiency, may need help from a qualified tax professional.

Important note

This is general information, not legal, tax, financial, or professional advice. Tax notices and deadlines vary by agency, letter type, and audit stage. If you are unsure what you received, cannot meet the deadline, or think serious penalties may apply, seek qualified help promptly.
