IRS Reference Code 1121: The IRS Stopped Your Refund or Got It Back
By Forrest Baumhover, CFP®, EA · Last verified November 12, 2026
Reference code 1121 means the IRS found a problem with your refund and put a hold on it that the manual calls a P- freeze. The causes include a bank rejecting the direct deposit, a check you sent back, and an IRS review that stopped the refund before it went out.
What the IRS list says
Exhibit 21.4.1-3 of the Internal Revenue Manual describes code 1121 as "Problem identified; P- Freeze" and points to the P- freeze section, IRM 21.5.6.4.31.
What sets a P- freeze
The manual lists the triggers: a financial institution returning part of a refund, an erroneous refund repayment, a rejected direct deposit, a paper check the taxpayer sends back, or a refund "stopped prior to issuance."
On an account transcript, a bank return shows as TC 720 and a stopped or returned refund as TC 841. The manual handles refunds stopped by the IRS's Return Integrity Verification Operations (RIVO) under a separate procedure, IRM 21.5.6.4.31.2.
If the bank rejected your direct deposit
The IRS mails a CP53E. The manual tells staff to direct you to "follow instructions provided in the CP53E notice," which let you add bank details in your IRS online account within 30 days or, in limited cases, ask for a paper check, and to "allow 4 weeks for their refund after submission of their information."
What to do
If you received a CP53E, act on it. If you did not, check your mail and, if you have one, your IRS online account for notices, then call the number Where's My Refund shows with the code.
The index of all 38 codes covers the other holds.
What people mistake code 1121 for
Some people read code 1121 as a lost refund. The money sits back on the IRS account: the manual says the transaction "credits the tax module for the returned, canceled, or deleted refund."
