A federal tax return held for an identity check can take up to nine weeks to process after the taxpayer verifies through the IRS online service, the agency says. On its Identity and Tax Return Verification Service page, updated Aug. 10, the IRS tells people to wait two to three weeks after verifying before checking on a refund. The wording is “may take up to 9 weeks,” a ceiling and not a promise.
The wait begins with a notice in the mailbox. The service is meant for people who received a CP5071 series notice or Letter 5447C, and the IRS says to use it only in that case. A taxpayer holding either one, with a refund riding on the return, should know the clock does not start until the verification is complete.

What does the verification involve?
Taxpayers sign in or create an IRS account, then answer a few questions to confirm the return. The IRS says to have the notice in hand along with the original or amended Form 1040 series return for the year named on the letter; if the copy is missing, tax software or a preparer will have it. After verifying, people generally do not need to file Form 14039, the identity theft affidavit, unless the IRS tells them to.
Taxpayers under 18 cannot use the service and are told to contact the IRS instead. The page also covers people who never filed. Someone may have tried to file a return with their information, and the service lets them tell the IRS. The agency says people who cannot verify online should follow the instructions in the notice or letter.
Why is the return not moving in the meantime?
The Taxpayer Advocate Service, an independent office inside the IRS, explains the hold in a tax tip by Toshia Hansen, published in March and updated Aug. 7. When the IRS questions a return, it sends a letter asking the taxpayer to authenticate, and it does not process the return or issue a refund until the taxpayer responds and finishes authentication.
Flagged returns, the tip says, show a transcript code 570, which signals a processing delay, and a code 971 appears once a notice or letter is issued. The tip draws its statistics from National Taxpayer Advocate Erin M. Collins’s 2024 report to Congress.
That sets the sequence out in order: the hold, the letter, the verification and then the processing window with the nine-week ceiling. The tax tip does not repeat the nine-week figure, which comes from the IRS verification page.
For Letter 5071C, the Advocate Service’s notice page says to respond within 30 days of the date on the letter. Until identity is verified, the IRS will not issue a refund or apply an overpayment to next year’s estimated tax. The page says the online verification service is available around the clock, while the toll-free line printed on the letter is for identity verification only and cannot give refund status or other tax information. Authorized third parties can help, but the taxpayer has to be on the phone or present in person.
Anyone who cannot verify by phone may be asked to make an in-person appointment at a local IRS office, and appointments are scheduled at 1-844-545-5640. The same page repeats the nine-week figure for the refund after verification and warns that other issues on the account could trigger a further notice and more delay.
Which letter is it?
The Advocate Service tip lists four letters tied to these holds. Letter 5071C offers online and phone options and is the most common. Letter 4883C carries a phone option, 5447C offers phone and mail options for international taxpayers, and 5747C is in person only and rarely used.
Letters can offer online, phone or mail options and, in limited cases, an in-person appointment at a Taxpayer Assistance Center. A taxpayer who cannot find the letter can check an IRS online account or call the Taxpayer Protection Program at 800-830-5084, or 267-941-1000 from outside the United States, according to the tip.
How does nine weeks compare with an ordinary refund?
The IRS says on its refunds page, updated Oct. 16, that an e-filed return generally shows a refund about three weeks after filing and a mailed return takes six or more weeks from the date the IRS receives it. Returns that need corrections or further review take longer.
That page does not mention identity verification, so the nine-week ceiling on the verification page is the figure that applies once a taxpayer has completed the service. The three-week and six-week markers describe returns that never hit a hold.
The IRS advice is to wait two to three weeks after verifying, then check. Keeping the notice, the verification date and the date of each status check in one place makes a later call to the IRS far easier.
Waiting on a refund held for an identity check?
The IRS does not issue a refund until identity is verified, a letter asks for a response within 30 days, and after that processing can take up to nine weeks. A taxpayer who loses track of the letter or the dates can spend those weeks guessing.
The IRS Refund Recovery Kit includes a notice decoder and a refund status tracker spreadsheet, plus a section on passing identity verification. The 20-page kit also explains how to read refund status and why a refund stalls.
