Form 3911 Fax Number: Where to Send Your Refund Trace
Where to Fax Form 3911 for Individuals and Businesses
There is no universal Form 3911 fax number. For an individual refund trace, use the IRS route for the state where you live or the international category. Businesses use separate Cincinnati or Ogden routes. Check the destination before sending your signed form.
What is IRS Form 3911?
Form 3911, Taxpayer Statement Regarding Refund, gives the IRS the information needed to trace an issued refund that you did not receive, or a refund check that was lost, stolen or destroyed. It is a refund inquiry, not a tax return or a request to speed up a return that is still being processed.
The form includes individual and business returns and asks whether the refund was a check or direct deposit. Download the current IRS Form 3911 PDF and follow any instructions the IRS sent with your refund inquiry.
Where to Fax Form 3911
There is no single Form 3911 fax number. For individuals, choose the state where you live from the list below, unless you fall into the international category. Business entities use the separate routes after that list. If the IRS supplied a fax number on your form or specific instructions for your inquiry, follow those instructions.

What to check before faxing your refund trace
- Use a separate form for each refund. Complete the entire form; mark sections that do not apply as N/A.
- Check the identifying details. Include your current name, taxpayer identification number, address and daytime phone number. If the name or address on the return differs, enter it as requested on line 4.
- Identify the refund. Check the return and refund type, and enter the refund amount, tax period, filing date and applicable bank information.
- Sign and date it. Both spouses must sign for a refund from a joint return. For a business return, the person authorized to sign the check signs and enters their title.
- Review the destination and pages. Use the correct individual, international or business route. Check that the scan is complete and readable; send only Form 3911 to the listed lines.
- Keep your records. Save your completed form and fax confirmation with the destination, date and page count. Transmission confirmation does not establish that the IRS has reviewed the form or completed the trace.
If you still have a refund check that was not cashed within one year of its issue date, the form directs you to contact the IRS for instructions on returning it. Do not treat the general lost-check process as instructions for that situation.
When is Form 3911 used?
The refund trace process covers these situations:
- You did not receive a refund the IRS has already issued.
- Your refund check was lost, stolen or destroyed.
- The IRS asked you to complete Form 3911 for a refund inquiry.
Check your refund status and the applicable IRS instructions before starting a trace. For an expected paper check and a filing status of Single, Married Filing Separately or Head of Household, the IRS encourages starting with its self-help methods, including Where’s My Refund?. Form 3911 is not a general remedy for every delayed refund.
Is there one IRS fax number for Form 3911?
No. Individuals use the route for the state where they live, with a separate route for international and other listed cases. Business entities use Cincinnati or Ogden. Follow any destination the IRS supplied for your refund inquiry and confirm the current routing before sending.
Can I mail Form 3911 instead of faxing it?
Yes. The IRS publishes mailing addresses alongside the Form 3911 fax routes. If the IRS sent you the form with a return envelope or a destination for your case, follow those instructions. Use one submission route unless the IRS asks you to send another copy.
Do both spouses need to sign Form 3911?
Yes, when the refund is from a joint return, both spouses must sign before the IRS can begin a trace. For a business return, the person authorized to sign the refund check signs the form and enters their title.
Can I use Form 3911 for more than one refund?
Complete a separate Form 3911 for each refund you want traced. Identify the return type, refund type, amount, tax period and filing date for that refund, and complete the applicable sections.
Does fax delivery mean my refund trace is complete?
No. A successful fax confirmation records transmission to the receiving fax system. It does not confirm IRS review, completion of the trace or issuance of a replacement refund. Keep the completed form and delivery confirmation for any follow-up.
