Getting an IRS 5071C letter in the mail often creates confusion and concern. Taxpayers may wonder why the agency contacted them or what it really means. This notice is not a punishment but a precaution the IRS uses to confirm your tax return details and safeguard your identity from fraud.
This letter often appears when the IRS systems detect unusual activity tied to a Social Security number or tax return. Sometimes the system flags a legitimate return; in other cases, it uncovers an attempt by another person to file using your identity. In both situations, the IRS needs you to verify your identity before completing the verification process and moving your return forward.
Taking action quickly is the best way to prevent delays with your refund and avoid complications. Ignoring the requests could result in weeks of waiting, rejected returns, or additional enforcement steps.

What Is an IRS 5071C Letter?
An IRS 5071C letter is a notice sent by the Internal Revenue Service to taxpayers when there is a question about the validity of a tax return. It does not mean you are in trouble, but the IRS needs to confirm whether you genuinely filed the return or if it may be connected to identity theft.
The letter will arrive by mail, containing details such as your name, a portion of your Social Security number, and a number provided for completing the verification process. One key detail to look for is the locked padlock icon when you go online to verify your identity. This indicates that you are on the official IRS website, not a fraudulent page.
Why the IRS Sends This Letter
- Potential fraud detected: The IRS may notice that your return looks unusual compared to prior year filings or schedules, which can trigger identity verification requests.
- Duplicate filing activity: A second return may have been filed under your Social Security number, raising concerns about fraud.
- Security measure for taxpayers: Even if you did file the return, the agency will still ask you to verify your identity before processing it further to protect your refund.
Why Did You Receive This Letter?
The IRS sends a 5071C letter when its system flags something unusual with a tax return tied to your Social Security number. While it may feel stressful to receive this notice, the primary purpose is to protect your identity and prevent fraud.
This letter follows two everyday situations. Understanding which applies to you will help guide your next steps in the verification process.
Scenario 1: You Filed a Tax Return
- Routine verification: Your return may look different from filings or schedules from the prior year, prompting the agency to ask you to verify your identity.
- Protective measure: Even if everything is accurate, the IRS may require confirmation to ensure no one else uses your information.
Scenario 2: You Did Not File a Tax Return
- Identity theft warning: Another person may have used your Social Security number to file a return without your knowledge.
- Action required: You must notify the IRS and complete the verification process to validate your identity and secure your account.
Consequences of Ignoring IRS 5071C Letter
Failing to respond to an IRS 5071C letter can create serious problems for taxpayers. The agency treats unanswered notices as unresolved identity verification, which can delay your refund and lead to enforcement action. Taking the proper steps quickly helps protect your return and limit complications.
Processing Delays
- Refund frozen: Your return will not proceed until you verify your identity.
- Extended timelines: Refunds may be held for weeks or even months.
- Return rejection: If you never respond, the IRS may reject the filing entirely.
Financial Impact
- Accrued penalties and interest: Unpaid balances continue to grow while the account remains unresolved.
- Increased costs: Delays can result in late payment penalties, increasing your bill.
IRS Enforcement Actions
- Tax liens: The IRS may place claims against your property.
- Bank levies and wage garnishments: Funds can be taken directly from accounts or paychecks.
- Seizure of assets: Property, vehicles, or real estate could be at risk in severe cases.
- Audit selection: Failure to respond may raise red flags for additional reviews.
Ongoing Identity Theft Risks
- Future fraudulent returns: Someone could file under your Social Security number without verification.
- Credit damage: Identity thieves may use your information to open accounts or access benefits.
Step-by-Step Verification Process
When you receive an IRS 5071C letter, the IRS expects you to complete the verification process before your return can proceed. The agency offers several ways to verify your identity depending on your situation.
Step 1: Check That the Letter Is Genuine
- Look for official details: The letter should include your name, a portion of your Social Security number, and a number provided for verification.
- Mail format: Genuine IRS letters come from the Department of the Treasury and never arrive by email.
- Locked padlock icon: When verifying identity online, confirm you see this symbol to ensure you’re on the secure IRS website.
Step 2: Verify Your Identity Online
- Fastest option: Use the IRS identity online service to verify your identity.
- Required documents: Prepare your current and prior year tax returns, W-2s, and other schedules.
- System questions: The IRS may ask questions only you can answer, such as details from prior filings.
Step 3: Use the Toll-Free Number
- Call the number provided: The letter lists a toll-free number to complete verification.
- Be prepared: Calls may last 30–60 minutes, and the IRS will ask detailed questions about your return.
- Limitations: This line is only for identity verification, not general refund or tax questions.
Step 4: In-Person Verification
- Schedule an appointment: If phone or online verification doesn’t work, you may be asked to visit a local IRS office.
- Bring documents: Government-issued ID, tax forms, and schedules from the prior year may be required.
- Result: Once the IRS validates your identity, your return can continue through processing.
Taxpayer Relief Options After Verification
Once your identity verification is complete, the IRS may still determine that you owe a balance or have penalties for your return. The agency offers several relief options to help taxpayers resolve these issues in manageable ways.
Payment Plans and Installment Agreements
- Short-term plans: Pay the full balance within 180 days with minimal setup.
- Long-term plans: Spread payments over months or years, depending on the amount owed.
- Ways to apply: Payment plans can be set up online, by mail, or through the toll-free number listed on IRS.gov.
Offer in Compromise
- Settle for less: This program allows taxpayers to resolve tax debt for less than the full amount owed.
- Eligibility: You must show financial hardship or demonstrate that paying in full is impossible.
- Agency review: The IRS will carefully review your forms and schedules before deciding.
Penalty Abatement
- First-time relief: If you have a clean compliance history, you may qualify for one-time penalty removal.
- Reasonable cause: Illness, natural disasters, or other serious issues may justify penalty relief.
- Administrative review: In limited cases, the IRS may waive penalties due to delays or mistakes by the agency.
Pulling IRS Transcripts
- Why it matters: Transcripts help you review your account, confirm what the IRS has on file, and prepare responses.
- Types available: Account transcripts, return transcripts, and verification of non-filing letters.
- Ways to order: You can order online through the IRS identity service, by mail, or by calling the toll-free number.
Protecting Your Identity in the Future
Completing the verification process is essential, but taxpayers should also take measures to prevent future fraud. The IRS provides tools and guidance to help you secure your Social Security number and reduce identity theft risk.
Get an Identity Protection PIN
- What it is: It is a six-digit number issued by the IRS to validate your tax return.
- How it helps: It prevents another person from filing a return using your identity.
- Ways to apply: Request an IP PIN online through the IRS website after you verify your identity.
File Early Each Year
- Protect your return: Filing as soon as possible reduces the chance that someone else can file first using your information.
- Result: Early filing often means fewer delays and faster refunds.
Monitor Your Records
- Social Security statement: Review your SSA account yearly for signs of unauthorized earnings.
- Credit reports: Check for accounts or loans opened without your consent.
- IRS transcripts: Pull your records to confirm what the agency has on file.
Use Secure Communication
- Avoid email risks: The IRS will never ask for identity verification by email.
- Send forms carefully: Always use secure channels when mailing sensitive information.
- Look for the locked padlock icon: When entering personal details online, confirm you are on a protected page.
Frequently asked questions
How long does the verification process take?
If your details match IRS records, online verification is often completed the same day. Phone calls to the toll-free number usually last 30–60 minutes, while in-person visits may take longer. After the IRS verifies your identity, it can still take several weeks for your tax return to be processed and for any refund to be issued.
What if I didn’t file a tax return but received a 5071C letter?
If you did not file a return, the IRS will alert you that another person may have used your Social Security number. You should respond immediately, verify your identity with the number in the letter, and notify the agency of possible fraud to protect your account from further misuse.
Can someone else complete the verification for me?
Only you can verify your identity with the IRS. A tax professional may assist you during the process, but you must be present on the call or at an in-person meeting. If you want someone to act entirely on your behalf, you must file the appropriate authorization forms with the agency.
Does the IRS ever send identity verification requests by email?
No, the IRS will never ask you to verify your identity through email. Official communication arrives by mail, and the IRS directs taxpayers to secure websites identified by the locked padlock icon. If you receive an email claiming to be from the IRS, treat it as a scam and report it.
What happens if I ignore the letter?
Ignoring the 5071C letter can cause long delays and financial consequences. Your return may be rejected, refunds withheld, and penalties added to any balance due. The IRS may take action, such as liens or wage garnishments. Respond quickly and complete the verification process using the official IRS methods to avoid these results.
