Overview

An IRS identity verification notice means the IRS needs proof you filed the return or that your Social Security number belongs to you. These notices are triggered when the IRS detects something unusual—duplicate SSNs, mismatched names, or possible fraud—and are common tools to protect taxpayers (IRS Identity Verification Service).

Step 1 — Confirm the notice is legitimate

  • Check the notice number and the mailing address on the letter. Real IRS notices arrive by mail, not by email. If you’re unsure, use contact information on IRS.gov or the notice itself and confirm through the official IRS site (IRS tips for responding to notices).
  • Do not give personal data in response to unsolicited emails or phone calls. The IRS will not initiate identity-verification requests by email.

Step 2 — Read the notice and follow instructions exactly

  • The notice will tell you what the IRS needs and how to provide it: online, by mail to a specified address, or by phone/appointment. Follow that path unless you verify the contact through IRS.gov.

Step 3 — Gather the documents the IRS asks for

Commonly requested items include:

  • A government-issued photo ID (driver’s license or passport)
  • Social Security card, SSA printout, or Form W-2 that shows your SSN
  • Copy of the IRS notice you received
  • A copy of the tax return in question or a recent tax transcript
  • Proof of address (utility bill or bank statement) if requested

Redact unrelated account numbers (bank account numbers, etc.) before sending. Do not email scanned copies of SSNs unless the IRS specifically authorizes a secure method.

How to submit your documents

  • Online: Use the IRS Identity Verification Service link provided on your notice or the official IRS identity pages (IRS Identity Verification Service). The IRS offers secure upload options when available.
  • By mail: Send copies—not originals—to the address on the notice. Use certified mail or a tracked courier and keep copies for your records.
  • By phone or in‑person: Some notices give a phone number or invite you to a local Taxpayer Assistance Center by appointment. Verify the phone number on IRS.gov before calling.

If you suspect tax-related identity theft

  • File Form 14039, Identity Theft Affidavit, if instructed by the IRS or if you confirm someone filed using your SSN (IRS Form 14039).
  • Request an Identity Protection PIN (IP PIN) to prevent future fraudulent filings (Get an IP PIN — IRS).
  • Report identity theft to IdentityTheft.gov and to the three credit bureaus to place fraud alerts or freezes.

What to expect after you respond

  • Processing can take weeks. The IRS will send a confirmation letter once the verification is complete. Refunds held for identity verification are released after identity is confirmed.
  • If the IRS cannot verify identity with the documents provided, they may ask for additional proof or open an investigation.

Professional tips from practice

  • Respond quickly. In my practice, prompt and well-documented submissions reduce follow-up requests and speed resolution.
  • Keep organized copies of everything you send and a dated log of phone calls.
  • Use tracked mail or the IRS secure portal for uploads. Avoid sending sensitive documents via unsecured email.
  • If you’re unsure or the case is complex, consult a tax professional or an identity-theft specialist.

Common mistakes to avoid

  • Ignoring the notice. That can delay refunds and trigger more scrutiny.
  • Sending original documents when copies suffice.
  • Using contact info from an email or text without verifying it on IRS.gov.
