A very small percentage of taxpayers may see an 1121 reference number if they check “Where’s My Refund?” after they initially were provided a projected refund date by the tool. The IRS is aware of this situation, and emphasizes that the small group of taxpayers who see this reference number should continue checking Where’s My Refund for an update. If we need more information to process their return, we will contact them — usually by mail.
A Transaction Code 570 can mean different things in different cases so a taxpayer should not try to draw a conclusion based on the presence of a TC 570. The Transaction Code 570 will stop a refund from being issued until the impact of the action being taken on the account and the refund is determined and processed. Transaction Codes are used internally by the IRS to identify a transaction, adjust and research tax accounts and to maintain a history of actions posted to a taxpayer’s account. While they are reflected on transcripts they are not reflected on most public facing documents or tools like Where’s My Refund because they are difficult to interpret and can have different meaning depending on the case and associated codes and files. Again, the best way for taxpayers to check the status of their refund is by going to Where’s My Refund.
