Understanding Your CP01E Notice


This CP01E notice is issued to taxpayers who may be victims of identity theft because their social security number (SSN) and possibly their personal information were used for employment by someone other than the valid SSN owner.

What you must do

This notice is for informational purposes only. You don’t need to take any action at this time. Please continue to file all applicable tax returns timely.

You may want to

  • Review your earnings with the Social Security Administration to ensure their records are correct. You can create an account on the Social Security Administration's website.
  • Monitor your credit reports and all financial accounts for signs of misuse of your personal information.
  • Contact one of the three major credit bureaus to have a no-cost temporary “fraud alert” placed on your account:
    • Equifax: 888-766-0008
    • Experian: 888-397-3742
    • TransUnion: 800-680-7289

      You only need to contact one of the credit bureaus. When requesting a “fraud alert,” the bureau you contact must contact the other two.

Answers to common questions

I received a CP01E notice from the IRS. What does it mean?

The IRS became aware that your SSN was used by another person for obtaining employment, and we wanted to inform you so that you could take proactive actions to prevent further misuse of your SSN and other personal information. The CP01E is not a bill. The notice is for informational purposes only and will not result in any changes to your tax account. For more information on identity theft related to employment, visit the Employment Related Identity Theft page.

How long does the indicator remain on my account?

The indicator will remain on your tax account, unless you specifically request it be removed, because you indicated you are at risk of becoming a victim of tax related identify theft.

Who can I contact if I have questions related to my CP01E notice?

If you have a question regarding your notice and can’t find an answer on or one 
of the links on this page, don’t hesitate to contact the Identity Protection Specialized Unit at 
800-908-4490, Monday – Friday 7 a.m. – 7 p.m. your local time (Alaska & Hawaii follow Pacific Time ), and be sure to enter extension “477” when prompted. You will also find this telephone number on the upper right corner of your notice.

What is employment related identity theft?

Employment related identity theft occurs when someone other than the valid owner of an SSN, uses that SSN or other personal information without the valid SSN owner’s permission for the purpose of obtaining employment.

Can I find out who used my SSN for employment?

No. You won’t be able to find out who used your SSN. This notice was generated using an automated process that identified that someone used your SSN on a Form W-2 and attached to another return (known as a “mismatch”). Our systems do not capture the actual content of the 
W-2 that generated the notice.

Do I need to take any further actions to protect my tax account?

Because the use of your SSN for employment purposes does not affect your tax account, you don’t need to take any further actions for this issue.

Do I need to take any further actions to protect my identity?

Because your SSN was compromised and used for employment purposes, you may want to take additional protective actions to protect your personal information from further misuse. Review the information in your notice or visit the Identity Protection page or the Employment Related Identity Theft page for actions you can take to further protect your identity.

Who should I contact if I have more questions about my account related to identity theft but not related to the CP01E Notice or Employment Related Identity Theft?

The Identity Protection Specialized Unit can assist you with questions regarding identity theft related to your account. Contact us for specialized assistance at the general number
