If your tax refund is delayed due to identity theft concerns, the IRS has flagged your return as potentially fraudulent and frozen the refund until you prove you’re the person who filed it. Most people can clear the hold within about nine weeks of finishing verification. Confirmed identity theft cases, where someone actually filed a return using your Social Security number, take dramatically longer.
The path forward depends almost entirely on which notice the IRS sent you. Start there.
Why Your Return Was Flagged
The IRS runs every return through automated fraud filters. When something in your filing doesn’t match historical patterns or third-party data, the system pulls the return out of the processing queue and holds the refund. A flag doesn’t mean you’ve been victimized. It means the agency wants you to confirm the return is yours before it releases the money.
Find the Notice You Received
The IRS sends a specific letter, and the letter dictates which verification methods you can use.
The CP5071 series (CP5071, 5071C, and CP5071F) tells you a return was filed under your SSN and asks you to confirm whether it’s yours.1Internal Revenue Service. Understanding Your CP5071 Series Notice These can be resolved online, by phone, or in person.
Letter 5747C is different. It requires in-person verification at a Taxpayer Assistance Center and cannot be resolved online.2Internal Revenue Service. Understanding Your Letter 5747C
A CP01E notice is a boundary case worth flagging up front: it means someone used your SSN to get a job, not to file a return. It does not delay your refund, and you do not need to file Form 14039. The IRS has already placed a protective marker on your account.3Internal Revenue Service. Understanding Your CP01E Notice The rest of this article is about the refund-holding notices.
Keep your notice. Every verification step needs it. If you’ve lost it, check your IRS online account or call the Taxpayer Protection Program line at 800-830-5084.4Taxpayer Advocate Service. Identity Verification and Your Tax Return
How to Verify Your Identity
Online
Verifying online at IRS.gov is the fastest option for most people. You’ll sign in through an ID.me account, which requires a government-issued photo ID and a selfie taken with a smartphone or webcam.5Internal Revenue Service. New Identity Verification Process to Access Certain IRS Online Tools and Services Online verification is only available if you received a CP5071 series notice or Letter 5447C.6Internal Revenue Service. Verify Your Return After signing in and answering a few questions, you can also use the tool to report that you did not file the return in question.
By Phone
Your notice includes a dedicated identity verification phone number. Call that number, not the general IRS line. Have the notice, a copy of the return you filed, and a prior-year return ready before you call.1Internal Revenue Service. Understanding Your CP5071 Series Notice Hold times run long from January through April.
In Person
If you received Letter 5747C, in-person verification at a Taxpayer Assistance Center is required. For other notices, it’s a fallback when online and phone don’t work. Call the toll-free number on your letter to schedule an appointment; walk-ins for identity verification generally aren’t accommodated.2Internal Revenue Service. Understanding Your Letter 5747C Bring the letter, the return referenced in it, supporting W-2s and 1099s, a prior-year return if you have one, and a current photo ID. A second form of ID may be requested.7Internal Revenue Service. Contact Your Local IRS Office
What to Have Ready
Whichever method you choose, gather the following before you start. People who contact the IRS without their records often end up calling back multiple times.
- The IRS notice or letter itself, which carries the control number you’ll need
- Your completed Form 1040 for the year in question, with all schedules
- Income documents: W-2s, 1099s, and any other forms supporting the return
- A prior-year return, used for additional authentication
- A government-issued photo ID
If you did not file the return that triggered the notice, you still need the photo ID and the notice to report it.6Internal Revenue Service. Verify Your Return
How Long Until the Refund Arrives
After you successfully verify, the IRS says to wait two to three weeks before checking your refund status, and up to nine weeks for the return to finish processing.6Internal Revenue Service. Verify Your Return That clock starts only when verification is fully complete. If the IRS sends a follow-up notice asking for more information, the clock resets when you respond.
One partial consolation: when the IRS holds an overpayment past a certain point, it owes you interest. Federal law says interest begins accruing if the refund isn’t issued within 45 days of the filing deadline (or 45 days after the return is filed, if filed late). For the quarter beginning April 1, 2026, the IRS pays 6 percent interest on individual overpayments.8Internal Revenue Service. Internal Revenue Bulletin: 2026-08 You don’t need to ask for it. The IRS calculates and includes the interest automatically when the refund is released.
If You Didn’t File That Return
This is where things get more serious. If someone else filed using your SSN, you’re dealing with confirmed identity theft, not a routine verification hold.
Use the verification process (online, phone, or in person) to tell the IRS you did not file the return. The agency will remove the fraudulent return from your account.9Internal Revenue Service. How IRS ID Theft Victim Assistance Works If you’ve already gone through the Taxpayer Protection Program verification, you do not need to separately file Form 14039 (Identity Theft Affidavit) unless the IRS specifically instructs you to.6Internal Revenue Service. Verify Your Return
Then file your own legitimate return on paper and mail it in. If you haven’t already responded to a Taxpayer Protection Program notice, attach Form 14039 to the back of the paper return.9Internal Revenue Service. How IRS ID Theft Victim Assistance Works You can also submit Form 14039 electronically through the FTC’s IdentityTheft.gov portal.
Be realistic about the timeline. According to the National Taxpayer Advocate’s 2026 mid-year report to Congress, the IRS had roughly 387,000 identity theft cases in inventory, with an average resolution time of about 20 months.10Taxpayer Advocate Service. NTA Issues Mid-Year Report to Congress 2026 That’s not a typo. Plan around it.
Steps to Take Beyond the Tax Hold
Someone with your SSN may also be opening credit accounts or applying for loans in your name. Move on these promptly:
- Place a fraud alert with one of the credit bureaus: Equifax (800-525-6285), Experian (888-397-3742), or TransUnion (800-680-7289). The one you contact is required to notify the other two.
- File a report at IdentityTheft.gov. The FTC portal creates a personalized recovery plan and can transmit Form 14039 to the IRS.
- File a police report. Some creditors require one before reversing fraudulent charges or accounts.
- Call the IRS Identity Protection Specialized Unit at 800-908-4490 for help with tax account issues caused by the theft.11Internal Revenue Service. Reporting Identity Theft

Without the correct IP PIN, no one can file a federal return using your Social Security number.12Internal Revenue Service. Get an Identity Protection PIN It’s the single most effective tool for preventing repeat tax identity theft.
Once you enroll, the IP PIN must be used on every federal return you file going forward, including current-year and any delinquent returns.13Internal Revenue Service.

When to Bring in the Taxpayer Advocate Service
If months have passed with no resolution and the delay is causing real financial pressure, the Taxpayer Advocate Service may be able to intervene. TAS is an independent organization inside the IRS that steps in when a tax problem is causing hardship, when you’ve tried and failed to resolve the issue through normal channels, or when an IRS process isn’t working the way it should.14Internal Revenue Service. Form 911, Request for Taxpayer Advocate Service Assistance
To ask for help, submit Form 911 with supporting documentation. Include evidence of the hardship the delayed refund is causing: eviction notices, utility shutoff warnings, or unpaid medical bills.14Internal Revenue Service. Form 911, Request for Taxpayer Advocate Service Assistance Given the 20-month average on identity theft cases, TAS is worth pursuing when the delay is genuinely hurting you.
