Letter 4310C tells you someone may have tried to impersonate you using your name and Social Security number. The IRS caught it through its processing safeguards and resolved the issue.
Here's what the IRS did:
- Adjusted your tax account to show the correct return information.
- Placed an indicator on your account that flags every return filed with your SSN as a possible identity theft case.
- Will review those returns to make sure someone else isn't using your SSN to file.
What to Do
If you already filed your return for the tax year on the letter, you don't need to send anything right now.
If you haven't filed for that year, you must file a paper return. Mail it to the IRS Submission Processing Campus that serves your state, and follow the instructions in the letter. Keep a copy and use certified mail.
Keep filing your future federal returns the way you normally do. If the IRS has a problem processing one, it will contact you. The IRS won't use email to start contact with you or to ask for personal information. Treat any email claiming to be from the IRS about this as a scam.
Protect Yourself Going Forward
- Get an IP PIN. An Identity Protection PIN is a unique 6-digit number that helps the IRS verify your identity and accept your electronic or paper return. The IRS sends IP PINs by notice in December. If you want the protection right away, use the Get an IP PIN tool, verify your identity, and the IRS will assign one.
- Watch your financial accounts. If you see suspicious or unusual activity, follow the steps in Publication 5027, Identity Theft Information for Taxpayers.
- Keep this letter with your tax records.
If you have questions, call the IRS identity theft number shown in your letter or the number on your notice.
