What Form 3911 does
Form 3911 gives the IRS information to trace a refund that was issued but not received or was lost. It is not a request to speed up a return that the IRS has not processed.
Check the form before faxing
- For an individual refund, check Where’s My Refund? or another IRS self-service option first; some taxpayers can start a trace without faxing.
- Complete and sign Form 3911 using the refund and taxpayer information requested by the IRS.
- Turn off OneFaxNow’s optional cover page and do not add other documents. The IRS says to send only Form 3911 to the refund-unit fax numbers listed on its page.
Where to fax Form 3911
For an individual refund, use the state row on the IRS Form 3911 page. The IRS has a separate row for foreign or U.S. territory addresses, APO/FPO addresses, and certain special filings. For a business refund, use the “For business entities” section; it routes to Cincinnati or Ogden with state exceptions.
Those numbers are reserved for Form 3911. Do not use them for a tax return, other IRS form, or general correspondence.

Questions about Form 3911
Can I add a cover page to Form 3911?
The IRS says not to send anything other than Form 3911 to the refund-unit fax numbers. Leave OneFaxNow’s optional cover page off.
Will faxing Form 3911 instantly replace my refund?
No. It starts or supports the IRS trace process for a refund already issued. The IRS handles any replacement separately.
