Letter 5216C,

Taxpayer Cannot Authenticate 

Where am I on the Roadmap?

Overview

The IRS is unable to verify your identity to finish processing your return. 

I need more information

1.

What does this mean to me?

The IRS received your individual income tax return but needs additional information to verify your identity 

The letter also provides you with your right to file suit in either your U.S. District Court or the U.S. Court of Federal Claims to recover your refund plus interest.

How did I get here

You submitted your individual income tax return and the IRS was not able to verify your identity to complete the processing of your return based on the information you previously provided.  This letter is being sent to you because more information is needed to complete the processing of your individual income tax return.

This documentation to verify your identity can include: 

  • A State issued identification card  
  • Driver’s license 
  • U.S. passport or passport card 
  • U.S. military card (front and back)  
  • Permanent Resident Card  
  • Certificate of Citizenship or Naturalization

Verify the return address on the letter

The first thing to do is to check the return address on your letter to be sure it’s from the IRS and not some type of a scam to obtain personal information from you.  If you suspect the letter to be a scam, report it to the IRS at Report Phishing.

Respond to the letter

If the letter is authentic, read the letter carefully and call the toll-free phone number listed on the letter to determine what information the IRS needs to verify your identity and complete the processing of your return. 

Don’t send another copy of your return unless the IRS asks you to do so. Do not file a Form 1040-X, Amended U.S. Individual Income Tax Return. After the IRS receives the requested information, they’ll use it to process your original tax return.

You may have a refund

If you’re entitled to a refund, the IRS will send it about nine weeks from the time they receive your response, plus any applicable interest. 

If you choose, you may be represented by a third party such as an attorney, certified public accountant, or enrolled agent. Also, you may be represented by a member of your immediate family, or a student or law graduate working in a low-income taxpayer clinic or student tax clinic program.  If you want your representative to advocate on your behalf and appear without you before the IRS, you must file a properly completed Form 2848 (no earlier than 01/2021 revision), Power of Attorney and Declaration of Representative. You may also authorize an individual to receive or inspect confidential material but not represent you before the IRS, by filing a Form 8821, Tax Information Authorization. These forms are available at your local IRS office, by calling 1-800-829-3676, or from www.IRS.gov.

Bring the following identity verification documents to your appointment:

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

And at least ONE of the following forms of identification: 

  • Current federal or state government-issued identification that is different from the first document provided 
  • U.S. Social Security card 
  • Mortgage statement with current address 
  • Lease agreement for a house or apartment with current address  
  • Car title  
  • Voter registration card (not the voter registration application) 
  • Utility bill matching address on ID 
  • Birth certificate (the IRS no longer accepts Puerto Rican birth certificates issued before July 1, 2010) 
  • Current school records

Once you have successfully verified your identity, the IRS will continue processing your tax return.  It may take up to nine weeks for you to receive your refund plus any applicable interest, or apply the overpayment to next year’s estimated tax. You can visit Where’s My Refund? on irs.gov or on the IRS2Go mobile app after two – three weeks from verifying your identity.

However, if there are other issues, you may receive a notice asking for more information and this may delay your refund.
