IRS Letter 4883C: What It Means and How to Verify by Phone
The IRS holds a return filed under your SSN or ITIN until you call its Taxpayer Protection Program hotline and verify your identity.
Reply by the date on the notice
The IRS gives no fixed number of days and says to call immediately; nothing on the return, including any refund, moves until you verify.
Letter 4883C means the IRS received a Form 1040-series return under your SSN or ITIN and won't process it until you confirm your identity and the return. The IRS asks you to call the Taxpayer Protection Program hotline on the letter right away, with the letter, the return and your supporting documents in hand. If you didn't file a return for that year, tell the IRS on that call.
What this notice is telling you
- A Form 1040-series return was filed under your SSN or ITIN, and the IRS has stopped it to protect you from identity theft.
- Until you verify, the IRS will not process the return, issue a refund or apply an overpayment to another year.
- Verification for this letter happens by phone, through the Taxpayer Protection Program hotline printed on the letter.
- If phone verification doesn't work, the IRS will ask you to make an in-person appointment at a local IRS office.
- If you didn't file a return for the year shown, the letter may mean someone else filed one using your information.
What to do
Pull together the four things the IRS asks for
Have the 4883C letter, the Form 1040-series return named in it, a return for a different year if you filed one, and the supporting documents for each year such as Forms W-2 and 1099 and any Schedule C or F. A W-2 or 1099 on its own is not a tax return.
Call the hotline on your letter
Use the Taxpayer Protection Program number printed on your 4883C, and call promptly. The line handles identity and return verification only, so refund status and other account questions go elsewhere.
Decide who will be on the call
A representative can call on your behalf only if a Form 2848 power of attorney is on file. Without one, you and the person helping you must call together and you must take part. A fiduciary acting for a taxpayer files Form 56.
Skip the identity theft affidavit
The IRS says not to file Form 14039 if you received this letter. Follow the letter's instructions and give the information asked for on the call.
Allow time after you verify
Once verified, the IRS says a refund can take up to nine weeks. If something else turns up on the return during processing, that can add time.
If you can't verify over the phone
If you can't complete verification by phone, the IRS will ask you to schedule an in-person appointment at a local IRS office and bring the required documents. Bring the same set listed on your letter: the letter, the return for that year, another year's return if you have one, and the supporting forms.
Incarcerated taxpayers who receive a 4883C need to coordinate the call with prison officials.
If the return isn't yours
Tell the IRS right away on the hotline that you did not file a return for the year on the letter. The IRS treats this as possible identity theft, and the call is how it learns the return was not filed by you. If you still need to file your real return for that year, mention it so the account can be sorted out.
After the immediate issue is dealt with, consider an Identity Protection PIN. It is known only to you and the IRS, it changes each calendar year, and the IRS says it will never ask you for it by phone, email or text.
What happens if you do nothing
- The return stays unprocessed for as long as you don't verify.
- Any refund on it is not issued, and any overpayment is not credited.
- If someone else filed the return, ignoring the letter leaves you without the IRS hearing from you that it was fraudulent.

Questions about Letter 4883C
Can my tax preparer call the 4883C hotline for me?
Only if a Form 2848 power of attorney naming them is on file with the IRS. Without one, you and the preparer can call together, but you must take part in the call.
Can I verify a 4883C online instead of calling?
The IRS page for Letter 4883C directs you to the Taxpayer Protection Program hotline on the letter, with an in-person appointment if phone verification doesn't work. The online verification service is described for the CP5071 series, not this letter.
Should I send copies of my W-2s with the letter?
The IRS asks you to have them ready for the call rather than mail them in. Follow the instructions on your own letter.
Will verifying get my refund released right away?
No. The IRS says a refund can take up to nine weeks after successful verification, and other issues found on the return can delay it further.
