IRS Form 3911: Filing Steps, Mailing, and Refund Tracing

IRS Form 3911, the Taxpayer Statement Regarding Refund, is the paper you file to open a formal trace on a federal refund the IRS says it issued but you never received. It also covers a refund check that arrived and then was lost, stolen, or destroyed before you could cash it. Filing it tells the IRS to work with the Bureau of the Fiscal Service (or, for direct deposits, your bank) to find out what happened and, in most cases, issue a replacement.

Before you send anything in, though, check whether a faster option will do the job.

Try the Faster Options First

You don’t always need to mail or fax a paper form to start a trace. Most individual filers can begin the process through the “Where’s My Refund?” tool at irs.gov, the automated refund hotline at 800-829-1954, or a live representative at 800-829-1040.¹ To use the online tool, have your Social Security number or ITIN, filing status, and the exact refund amount from your return ready.²

There is one exception. If you filed a joint return, the automated systems will not start a trace for you. You have to speak with a live representative or submit Form 3911.¹

When You Can File Form 3911

The form covers two scenarios, both of which assume the IRS has already processed your return and issued the refund.³

The refund never arrived. Your direct deposit didn’t post, or your paper check never showed up.
The check arrived and was then lost, stolen, or destroyed before you cashed it.

You also have to wait long enough. For direct deposits, wait at least five days after the deposit date shown in “Where’s My Refund?” For mailed checks, wait four weeks from the issue date, or six weeks if you live outside the state where the check was issued.³ File earlier and the IRS will tell you to wait.

How to Fill Out Form 3911

The form is a single page in three sections. Keep your original return next to you as you fill it in, because several fields have to match it exactly.⁴

Section I: Taxpayer and Return Information

Enter your current name, Social Security number or ITIN, and address. On Line 2, add your spouse’s name if the refund came from a joint return. Line 4 asks for the name and address as they appeared on the original return; write “N/A” if nothing has changed.

This section also captures the tax year, the type of return, the date you filed, whether you asked for a check or direct deposit, and the exact refund amount. If direct deposit, you have to provide the bank name, routing number, and account number from your original Form 1040. That banking information is what the IRS uses to trace the deposit through your financial institution.⁴ Lines 5 and 6 are for a representative you authorized to receive the check, if any.

Section II: What Happened

Line 8 gives you two boxes to choose from: you didn’t receive the refund at all, or you received the check and it was lost, stolen, or destroyed. Line 9 applies if you received and signed the check and then someone else cashed it.⁴

One limit is worth noting up front. If you endorsed the check yourself and another person then cashed it, the IRS cannot issue a replacement, because no forgery occurred.⁴

Section III: Signature

You sign under penalty of perjury that the information is accurate and that you’re asking for a replacement. Built into the certification is a promise that if you end up with two refunds, you’ll return one. For a joint return, both spouses must sign before the trace begins.⁴ If more than one refund is missing, file a separate Form 3911 for each.

Where to Send It

You can fax or mail the form, and the destination depends on the state you live in.³ Faxing is usually faster. The fax numbers by state group:

Maine, Maryland, Massachusetts, New Hampshire, Vermont: 855-253-3175 (Andover)
Georgia, Iowa, Kansas, Kentucky, Virginia: 855-275-8620 (Atlanta)
Florida, Louisiana, Mississippi, Oklahoma, Texas: 855-203-7538 (Austin)
New York: 855-297-7736 (Brookhaven)
Alaska, Arizona, California, Colorado, Hawaii, Nevada, New Mexico, Oregon, Utah, Washington, Wisconsin, Wyoming: 855-332-3068 (Fresno)
Arkansas, Connecticut, Delaware, Indiana, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, Ohio, West Virginia: 855-344-9993 (Kansas City)
Alabama, North Carolina, North Dakota, South Carolina, South Dakota, Tennessee: 855-580-4749 (Memphis)
District of Columbia, Idaho, Illinois, Pennsylvania, Rhode Island: 855-404-9091 (Philadelphia)
Foreign country, U.S. territory, APO/FPO address, or filers of Form 2555 or 4563: 855-203-7538 (Austin)

Send only Form 3911 to these numbers, without other attachments.³ If you prefer to mail it, check the current instructions on irs.gov for the matching address, since they change from time to time.

What Happens After You File

Once your form is in, the trace runs differently depending on how the refund was issued. For paper checks, the IRS asks the Bureau of the Fiscal Service (BFS) whether the check was cashed. For direct deposits, BFS contacts the receiving bank to confirm whether the money arrived and, if so, where it went.⁵

Paper-check traces take about six weeks.⁵ Direct-deposit traces run longer because banks have up to 90 days from the trace date to respond, and full resolution can take up to 120 days.⁶ Peak season and complex cases push those windows out further.

If a paper check was never cashed, the IRS credits the amount back to your account and issues a new refund.⁵ If eight weeks pass without any word, call 800-829-1040 with your Social Security number and return details ready. Any interest the IRS owes on the delay is added to the replacement refund automatically, so you don’t need to ask for it separately.⁷

If the Check Was Cashed by Someone Else

When the trace shows your check was cashed but you never received or endorsed it, the IRS sends you a forgery claim package. It contains a photocopy of the cashed check and Claim Form FS 1133 from BFS.⁵

You fill out FS 1133 and sign it three times so BFS can compare your handwriting with the endorsement on the cashed check. Both payees sign if the check was issued to two people. Return the completed form together with the check copy to the BFS Check Resolution Division in Philadelphia. Without the check copy, BFS cannot process the claim.⁸

If Your Direct Deposit Went to the Wrong Account

If you entered the wrong routing or account number on your return and the money landed with someone else, the process is harder. The IRS does not take responsibility for taxpayer or preparer errors on banking details.⁶

Call the bank first and ask them to recover the funds. If five calendar days pass with nothing returned, file Form 3911 and the IRS will contact the bank on your behalf.⁶

Here is where the story can end badly. If the bank cannot recover the money or refuses to return it, the IRS has no authority to force the issue. Getting your money back becomes a civil matter between you and the bank or the person whose account received it.⁶

Expired Refund Checks

U.S. Treasury checks carry “VOID AFTER ONE YEAR” above the disbursing officer’s signature. Under the Competitive Equality Banking Act, a Treasury check that isn’t cashed within one year of issuance is automatically canceled, and the funds go back to the issuing agency.⁹

Don’t throw an expired check away, and don’t try to deposit it. Contact the IRS for instructions on returning it and asking for reissuance.⁴ The IRS can recertify the payment, but not on its own.

When Form 3911 Isn’t the Right Tool

Two situations look like missing refunds but call for a different form.

Identity theft. If the IRS tells you a return was already filed and a refund already issued, but you never filed that return, someone may have used your Social Security number. File Form 14039, the Identity Theft Affidavit, if you can’t e-file because your SSN is already in use, you get a tax transcript you didn’t request, a preparer contacts you about an account you didn’t open, or the IRS says you owe taxes on income you never earned. If you’ve already received IRS Letter 5071C, 4883C, or 5747C, follow the instructions in that letter rather than filing Form 14039.¹⁰

Refund offset. If you got a smaller refund than expected, the Bureau of the Fiscal Service may have reduced it under the Treasury Offset Program to cover past-due child support, federal agency debts, state income tax, or certain state unemployment debts. BFS sends a notice showing the original refund, the amount taken, and the agency that received it. Dispute the debt with that agency, not the IRS. If you didn’t get the notice, call the BFS TOP call center at 800-304-3107, Monday through Friday, 7:30 a.m. to 5 p.m. CST.¹¹ Form 3911 won’t help here, because BFS delivered the refund as intended.

The Deadline to Claim a Refund

There is a hard outer limit. You must file a refund claim within three years of the date you filed the original return or two years from the date the tax was paid, whichever is later.¹² Miss that window and the IRS legally cannot pay you, no matter how clearly you’re owed the money.

If you file after the three-year mark but within two years of paying the tax, your refund is capped at the amount you actually paid in those two years. This matters most when withholding was heavy in one year and the return wasn’t filed right away.¹³

If the IRS Denies Your Claim

A denial comes as Letter 105C or Letter 106C, which explains the decision. You can appeal in writing to the IRS Independent Office of Appeals, sending your explanation and supporting documents to either the address on the denial letter or the IRS office where you filed the original return.¹⁴

If the appeal doesn’t resolve things, you have two years from the date of the disallowance letter to file a refund suit in U.S. District Court or the U.S. Court of Federal Claims.¹³
