IRS Identity Verification Letters: What To Do If You Get A 5071C Or 4883C

Getting an IRS identity verification letter can be stressful, there’s nothing to panic about most of the time. It’s just a routine security check. If you receive a 5071C letter or a 4883C letter, the IRS simply needs to confirm your identity before it can process your return and release your refund.

Let’s understand why you got the letter, what it means for you, and the exact steps to verify your identity with the IRS so you can avoid delays and get your refund faster.

Why The IRS Sent You An Identity Verification Letter

The IRS sends an IRS identity verification letter to protect taxpayers from identity theft and refund fraud. When something on your tax return looks unusual compared to past filings, the IRS pauses processing to confirm your identity. This is a routine security step, not a penalty or an audit, and responding quickly usually resolves the issue.

It does not mean you are being audited (yet)

Getting an IRS identity verification letter does not mean you are being audited. These letters like a 5071C letter or 4883C letter only ask you to verify identity IRS to make sure the return is yours. Most people who get these letters are not under audit. 

For example, a taxpayer received a 5071C letter, followed the instructions to verify identity with the IRS, and received their refund in just 10 days without being audited.

Common triggers: Address changes, new bank accounts, or high refunds

Many IRS identity verification letters are caused by normal life changes, not errors. Things like a new address, a new bank account, or a larger refund than usual can trigger a security check by the IRS.

Trigger	Why It Flags an IRS Identity Verification Letter	Real-Life Example	Prevention Tip
Address change	IRS database mismatch.	Moved from NY to FL mid-year.	Update USPS forwarding + IRS Form 8822.
New bank account	Unseen routing numbers.	Switched to an online bank.	Use the same account as the prior year.
High refund	Bigger than the historical average.	Side gig boosted return 50%.	File early to beat peaks.
Name/SSN tweak	Filing status shift.	Newly married, hyphenated name.	Double-check e-file preview.
Dependents added	New kids/pets on return.	First child credit claim.	Attach the birth certificate if questioned.

If any of these situations apply to you, don’t panic. They are common and easy to explain, and most taxpayers resolve their IRS identity verification letter quickly once verification is completed.

The Critical Difference Between Letter 5071C And 4883C

Your IRS identity verification letter lists the letter type in the top right corner. A 5071C letter allows online verification and is usually resolved faster, while a 4883C letter requires phone or in-person verification and takes more time to complete.

5071C: The online option letter (faster resolution)

The 5071C letter is the easiest and fastest way to verify your identity with the IRS. It lets you verify your identity with the IRS online using a secure website shown on the letter, along with a QR code or link. Most people finish the process in 10–15 minutes, and many get their issue resolved within a week.

Steps to complete verification:

• Scan the QR code or visit the link in the 5071C letter.
• Create a free ID.me account or sign in.
• Upload your photo ID and take a selfie (use good lighting).
• Enter the control number from your letter.

If the online system does not work for you, the 5071C letter also includes a phone option so you can verify another way.

4883C: The phone or in-person requirement (stricter security)

The 4883C letter is sent when the IRS needs extra confirmation of your identity. It requires live verification by phone and usually takes 45–90 minutes. In some cases, you may also need an in-person appointment through the Internal Revenue Service website.

What to expect:

• The letter says, Call 800-830-5084 immediately.
• Verification is done by phone with a Taxpayer Protection Program agent.
• Online verification is not allowed.
• In-person TAC visits may be required in certain cases.
• Resolution usually takes 4–9 weeks.

Always follow the instructions on your IRS identity verification letter, as using the wrong method can delay your refund.

How To Verify Identity With The IRS Successfully

Verifying your identity is much easier when you are prepared with the required documents. Most problems happen because people start the process without the right documents. Before you verify your identity with the IRS, gather everything listed on your letter to avoid delays.

Using the ID.me system vs. calling the TPP (Taxpayer Protection Program) line

• Available 24/7 with no wait time.
• Requires a phone or computer with a camera.
• You’ll upload an ID and take a selfie.
• Helpful video guides are available on the IRS YouTube.

TPP phone option (for a 4883C letter):

• Call 800-830-5084.
• An IRS agent will ask several identity and tax questions.
• Best time to call is early in the morning on weekdays.
• Calls usually take longer than online verification.

Both methods end with a confirmation number. Save it for your records.

Why is the Control Number on your letter the key?

The control number on your IRS identity verification letter links your verification to your tax return. Without it, the IRS cannot complete the process.

Helpful tips:

• Keep a copy of your letter (front and back).
• Write down your control number in a safe place.
• Share it with a tax professional only if you need help.

The Trick Questions: What Documents You Must Have Ready

When verifying your identity, the IRS will ask specific questions from your tax returns like a short, detailed review of your tax information. Having the right documents ready is the easiest way to avoid mistakes, failed verification, or a dropped call.

Prior Year Return: They will ask for specific line items (AGI, withholding)

The Internal Revenue Service will ask security questions based on your prior-year tax return, so keep a copy within reach before you start. These questions are very specific and usually include your Adjusted Gross Income (AGI), taxable income, and federal tax withheld. 

Answer carefully and use the exact figures shown on your return. Guessing, rounding numbers, or taking too long to respond can cause the verification call or session to end.

Current Year Return: You must match the numbers exactly

For your current-year return, precision is critical. The IRS system matches your answers directly against what was filed, and even a small mismatch can lead to verification failure or refund delays.

Have these ready:

• Exact refund amount (for example, $3,247).
• Bank details used for direct deposit.
• E-file confirmation or submission receipt.

Even small number mistakes, like a data entry error or using an estimate, can cause the verification to fail.

What Happens After You Verify (And When To Worry)

Once you complete identity verification, your tax return goes back into the normal IRS processing system. This step removes the security hold, but it does not mean your refund is released immediately. Some waiting time is normal, so patience is important at this stage.

The 9-week processing timeline vs. reality

The IRS states that it can take up to 9 weeks to process your return after identity verification. In real life, timing often depends on when you filed and how busy the IRS is.

What most taxpayers experience:

• During slower months, refunds may arrive in 2–4 weeks.
• During peak tax season (February through May), processing can take much longer.
• Delays are common even after successful verification.

You can check your refund status daily on the Internal Revenue Service website. Status messages usually move in this order, verified → processing → sent.

When verification fails: Moving to professional representation

Sometimes, identity verification doesn’t go smoothly even if you follow all the steps. If this happens, the IRS may ask for more documents or delay your refund further. In these cases, working with a tax professional can help resolve issues faster and reduce stress.

Warning signs to watch for:

• You fail verification multiple times.
• You receive a notice mentioning a fraud hold.
• Your refund has not arrived after 10 weeks

Next steps if problems continue:

• Review your IRS account transcript for clues.
• Speak with a certified tax resolution specialist.
• Get help with unfiled tax returns if required.

Tax professionals often use IRS authorization forms to speak directly with the IRS, which can reduce stress and help resolve issues faster.

Conclusion

An IRS identity verification letter is a common security check and not a sign of trouble. Follow the instructions on your letter and verify your identity as soon as possible to avoid refund delays. Most taxpayers resolve an IRS identity verification letter quickly once they respond correctly. If delays continue, professional help can speed things up.
