Before you send it

The IRS says you should receive a refund check "within 4 weeks from the date we issue it," so confirm that time has passed first. The issue date is in the IRS refund tracker or your online account.

Form 3911 is the taxpayer statement the IRS uses to trace a refund that was issued and never arrived. A filer whose status is single, married filing separately or head of household can start a trace on a current-year paper check in the refund tracker instead. A joint filer calls the IRS or sends Form 3911.

On the form:

  • Complete a separate Form 3911 for each refund.
  • Fill in every field, and mark any part that does not apply as N/A.
  • If the refund was from a joint return, both spouses must sign before the IRS can begin a trace.

Which unit takes your Form 3911

The IRS instruction is to find the state you live in and use that unit's address or fax number. The numbers are in the list above.

  • ME, MD, MA, NH, VT: Andover
  • GA, IA, KS, KY, VA: Atlanta
  • FL, LA, MS, OK, TX: Austin
  • NY: Brookhaven
  • AK, AZ, CA, CO, HI, NV, NM, OR, UT, WA, WI, WY: Fresno
  • AR, CT, DE, IN, MI, MN, MO, MT, NE, NJ, OH, WV: Kansas City
  • AL, NC, ND, SC, SD, TN: Memphis
  • DC, ID, IL, PA, RI: Philadelphia

The Austin unit also serves filers in a foreign country or a U.S. possession or territory, filers with an APO or FPO address, Form 2555 or 4563 filers, and dual-status aliens. Each unit also has a mailing address, on the IRS page in the sources below. There is no single national fax line for Form 3911.

Business entities

A business tracing its refund uses one of two other units, split by the Mississippi.

  • Cincinnati, (855) 307-3124: states east of the Mississippi, plus Arkansas and Louisiana
  • Ogden, (855) 578-2550: states west of the Mississippi, plus Wisconsin

How to send it

The IRS page says: "Do not send anything other than a Form 3911 to the fax numbers below." Save the signed form as a PDF or photograph it, upload only that, enter the fax number for your unit, and send. The IRS page for Form 3911 describes no acknowledgment. Keep your confirmation with the date you sent the form. It is a timestamped record that the IRS fax line took every page, and the proof-of-filing guide covers what it does not show.
