What this letter is about

You may need to visit a Taxpayer Assistance Center, so we can verify your identity and process your tax return accurately.

  • Have a copy of the 5747C letter you received and a copy of the tax return for the tax year shown in the letter.
  • You can use this option if you did or didn’t file a tax return.

Call the IRS Identity Verification number on your letter to tell us you did not file a tax return.

If you did file, schedule an in-person appointment.

Call our Taxpayer Assistance Center toll-free at the number on your letter.

Please note:

  • Authorized third parties may assist taxpayers, but the taxpayer must be present in-person.

Bring the following to your appointment:

  • The 5747C letter;
  • The income tax return referenced in the letter (the Form 1040 series return).
  • A previous year’s income tax return, other than the year in the letter, if you filed one.
    Note: A Form W-2 or Form 1099 is not a tax return.
  • Supporting documents that you filed for each year’s income tax return (Form W-2, Form 1099, Schedule C or F, etc.).

Bring the following Identity Verification Documents to your appointment:

  • A valid U.S. federal or state government-issued picture identification, such as a driver’s license, state ID, or passport.

If we don't hear from you:

We may not be able to process your return, issue refunds, or apply overpayments to next year’s estimated tax.
