IRS Business Identity Verification Checklist
Understanding IRS Identity Verification Letters
The IRS sends identity verification letters when it receives a federal income tax return filed under your Social Security number or individual taxpayer identification number. Still, it cannot confirm that you actually filed that return. This process protects taxpayers from tax-related identity theft and fraudulent tax return filing, focusing on confirming your identity as an individual taxpayer rather than auditing your tax records or examining your reported income.
Your tax return will not be processed, and no refund will be issued until you complete the verification process. You must confirm whether you filed the return in question before processing can continue.
Who Receives These Letters
You may receive an IRS identity verification letter if you filed Form 1040-series returns and the
IRS flagged your filing for potential identity theft. Letter 5071C provides an online verification option and is issued most widely to individual taxpayers. Letter 4883C instructs you to call the
IRS directly to verify your identity and confirm you filed the return.
Letter 5747C requires you to schedule an in-person appointment at a Taxpayer Assistance
Center to verify your identity with physical documentation. These letters apply only to individual income tax returns, including those filed by sole proprietors using Schedule C or farmers using
Schedule F.
Required Documents for Verification
The IRS requires specific personal identity documents when you respond to verification letters.
You must bring a valid federal or state government-issued picture identification, such as a driver’s license, state ID, or passport.
You also need at least one additional form of identification from the following list
- Current federal or state government-issued identification is different from the first
document
- U.S. Social Security card
- Mortgage statement with current address
- Lease agreement with current address
- Car title
- Voter registration card
- Utility bill matching your ID address
- Birth certificate
- Current school records
Gather the verification letter itself, the Form 1040-series tax return referenced in the letter, and supporting documents for that tax return, such as Form W-2, Form 1099, Schedule C, or
Schedule F. If the IRS requests additional verification, bring a prior-year tax return other than the year mentioned in the letter if available.
How to Respond to Each Letter Type
Different verification letters require different response methods based on the letter code you received. Follow the specific instructions provided in your letter rather than assuming all verification requests use the same process.
Letter 5071C response steps
1. Visit the IRS Identity Verification Service website using the URL provided in your letter.
2. Sign in to your IRS online account or create a new account.
3. Answer security questions to verify your identity.
4. Confirm whether you filed the tax return in question.
Letter 4883C response steps
1. Call the toll-free number provided on your letter.
2. Have your letter, tax return, and prior year return available during the call.
3. Answer questions to verify your identity over the phone.
4. Tell the IRS whether you filed the return referenced in the letter.
Letter 5747C response steps
1. Call the Taxpayer Assistance Center toll-free number on your letter to schedule an in-person appointment.
2. Bring all required identity documents and tax documentation to your appointment.
3. Complete Form 2848 if you want someone to represent you, or Form 56 if you are acting as a fiduciary.
4. Remember that you must be present to authenticate your identity, even if an authorized third party represents you.
Processing Timeline After Verification
The IRS officially states it may take up to nine weeks to process your tax return after you verify your identity. This timeline applies whether you verify online, by phone, or in person at a
Taxpayer Assistance Center.
Wait two to three weeks after you complete the verification process before checking your refund status through IRS online tools. Processing times can vary based on the complexity of your case and service center workload, but the official maximum remains nine weeks from verification completion.
Consequences of Ignoring Verification Letters
Ignoring identity verification letters means the IRS will not process your tax return, and your refund will remain frozen until you complete the verification process. Overpayments cannot be credited to your account or applied to future tax years while verification remains incomplete.
Your account will remain on hold, preventing you from accessing certain IRS online tools and services. Follow-up notices will arrive if you do not respond, but continued failure to verify can result in the return being rejected and investigated as potential tax fraud.
When to Report Identity Theft
Contact the Taxpayer Protection Program hotline immediately if you receive a verification letter but did not file a tax return. This situation indicates someone may have filed a fraudulent tax return using your Social Security number.
The IRS will block the suspicious return from processing and begin an identity theft investigation. You should also file Form 14039, Identity Theft Affidavit, to formally report the incident and protect your tax account, then consider obtaining an Identity Protection PIN through the IRS program to prevent future misuse.
Important Limitations and Clarifications
Verification letters apply only to identity and tax return verification, meaning you cannot obtain information about refund status, payment plan options, or other tax-related matters through the phone numbers listed on these notices. Representatives who handle identity verification have limited access to other account functions.
Schedule a separate appointment or call different IRS phone numbers if you need assistance with tax transcripts, account balance inquiries, or payment arrangements. Verification processes address only whether you filed the return in question and confirm your identity as the legitimate taxpayer.
