What is letter 4310C?
Letter 4310C is an official IRS notice that informs taxpayers about a potential identity theft incident involving their Social Security number. When the IRS detects a suspicious tax return or other activity using a taxpayer’s SSN, it sends this letter to notify the individual and provide details on what has been done to safeguard their account.
The letter indicates that:
- Someone may have tried to use your SSN to file a tax return.
- The IRS has resolved the issue using its internal safeguards.
- Your tax account has been updated to reflect accurate return information.
- A marker has been added to your account to flag future returns as potential identity theft cases for further review.
Pro Tip
Consider enrolling in the IRS Identity Protection PIN (IP PIN) program for added security. This unique six-digit number helps protect your tax account from fraudulent filings and provides an extra layer of identity verification when submitting your tax return.
How does letter 4310C impact you?
When you receive Letter 4310C, it means the IRS detected and addressed a potential identity theft situation involving your SSN. The letter’s main purpose is to inform you about the incident and ensure that your tax account reflects accurate information.
Here’s how the situation might affect you:
- Additional review for future returns: Since your account is now flagged for potential identity theft, any tax return filed under your SSN will undergo extra scrutiny to ensure it is legitimate. This may delay processing times for future returns.
- Enhanced identity protection measures: The IRS has placed indicators on your account to help detect and prevent further unauthorized activity.
- Ongoing monitoring: Your tax account will continue to be monitored for unusual activity.
While the IRS has resolved the immediate issue, it’s important to stay vigilant and monitor your financial accounts for signs of fraud.

What should you do when you receive letter 4310C?
Upon receiving Letter 4310C, follow these steps to ensure your account is secure and your identity is protected:
- Read the letter thoroughly: Understand the nature of the issue and what actions the IRS has taken. The letter will detail any changes made to your tax account and explain the steps for future tax filings.
- Review your financial accounts: Check for any unusual or unauthorized activity on your financial accounts, including bank statements and credit reports. If you notice suspicious activity, take action immediately.
- File a paper return if necessary: If you haven’t filed your tax return for the specified year, submit a paper return to the IRS submission center serving your state. The instructions will be included in the letter.
- Continue filing returns normally: For future tax years, file your returns as usual. The IRS will contact you if additional verification is needed. Avoid sharing personal information through email, as the IRS does not initiate contact this way.
- Consider an identity protection personal identification number (IP PIN): Register for an IP PIN for added security. This six-digit number helps verify your identity and protect your tax returns from fraudulent filings. You can apply for an IP PIN immediately by visiting the IRS website.
Pro Tip
If you receive Letter 4310C, regularly monitor your credit reports and bank statements for any unusual activity. Early detection of potential identity theft can help minimize damage and simplify the recovery process.
How to protect yourself after receiving letter 4310C
While the IRS has addressed the issue, taking additional steps to safeguard your identity is wise:
Register for an IP PIN
An Identity Protection Personal Identification Number (IP PIN) adds an extra layer of security to your tax filings. You will receive a new IP PIN each year, which the IRS will use to verify your identity when you file your tax return.
How to get an IP PIN:
- Visit the IRS’s official website to apply for an IP PIN.
- Verify your identity through the online system.
- Once issued, the IP PIN should be included on your tax returns moving forward.
Monitor your credit reports
Regularly reviewing your credit reports can help detect identity theft early. You’re entitled to a free credit report from each of the three major credit bureaus (Equifax, Experian, and TransUnion) annually through AnnualCreditReport.com.
Steps to take:
- Request your credit report from all three credit bureaus.
- Look for unfamiliar accounts or credit inquiries.
- Dispute any suspicious activity with the credit bureau.
Follow the steps in IRS Publication 5027
The IRS provides a detailed guide on identity theft prevention in Publication 5027, “Identity Theft Information for Taxpayers.” This guide includes steps for recovering from identity theft, such as reporting the crime to the Federal Trade Commission (FTC) and placing fraud alerts on your credit reports.
How to respond to the IRS if further action is needed
In some cases, the IRS may request additional information or documents to verify your identity. If this happens, follow these steps:
- Provide the requested information promptly: Send the requested documents to the IRS to avoid delays in processing your return. This may include a copy of your government-issued ID or other proof of identity.
- Contact the IRS identity theft hotline: Call 800-908-4490 if you have questions about your letter or the actions needed. The hotline is available Monday through Friday, 7 a.m. to 7 p.m. local time.
- Consider professional assistance: If the situation is complex or you are unsure about the steps to take, seek advice from a tax professional who has experience with identity theft cases.
Pro Tip
Contact the IRS directly using the phone number provided in the letter rather than searching for contact information online. This helps you avoid potential scams and ensures you are speaking with a legitimate IRS representative.
What happens if you ignore letter 4310C?
Ignoring Letter 4310C can lead to serious consequences, including:
- Delayed tax refunds: If your account remains flagged for identity theft, future tax return processing may be delayed.
- Unresolved identity theft issues: Failure to address potential identity theft can lead to further complications with your tax account.

Frequently asked questions
Can I still file my tax return electronically after receiving letter 4310C?
If you received letter 4310C, it is advised to file your tax return by mail for the specified tax year. The IRS uses additional identity verification measures to process your tax return due to the identity theft alert on your account. Filing electronically may not be possible in some cases because of these added safeguards. Follow the instructions in the letter to ensure your return is processed correctly.
What should I do if I suspect additional fraudulent activity on my accounts?
If you notice any unusual activity on your financial accounts or suspect other instances of identity theft, take action immediately. Contact your bank or financial institution to report suspicious transactions and consider placing a fraud alert on your credit reports. Additionally, file a complaint with the Federal Trade Commission (FTC) and consider filing a police report to document the incident. These steps can help mitigate further risk and protect your identity.
Will receiving letter 4310C affect my future tax refunds?
Receiving letter 4310C may affect the processing time for your future tax refunds, as returns filed with your Social Security number will be flagged for additional review. While this may delay the processing of your refund, these safeguards are in place to protect against fraudulent filings. To minimize delays, ensure all tax information is accurate and consider applying for an Identity Protection PIN (IP PIN) for future filings.
Can I use the IRS online services if my account is flagged for identity theft?
If your account is flagged for identity theft, you may encounter limitations when using some IRS online services, such as checking your refund status or accessing certain account information. In these cases, contacting the IRS by phone or visiting a local IRS office may be necessary to get assistance. Be prepared to verify your identity through additional documentation if required.
How long does it take to resolve an identity theft case with the IRS?
Resolving an identity theft case with the IRS can take several months, depending on the complexity of the case and the verification process. The IRS may need additional documentation to confirm your identity and correct your tax account information. Throughout the resolution process, continue monitoring your financial accounts and credit reports for any suspicious activity. Patience and thorough communication with the IRS will help ensure the matter is resolved as quickly as possible.
