As part of a broader push to modernize payments, the IRS has been phasing out paper refund checks. This tax season, that shift has triggered a surge in notices asking taxpayers to confirm or update their banking information.
These letters, known as CP53E notices, are landing in more than 1 million mailboxes, according to some congressional estimates.
Unfortunately, as you might expect, the spike in IRS correspondence has created an opening for fraudsters, who are reportedly creating convincing fake versions.

So, how do you know if your IRS refund letter is real? And what should you do if you get one? Here’s more to know and some red flags to watch.
Why CP53E IRS letters seem to be everywhere
Let’s start with why what’s happening is happening.
A CP53E notice from the IRS typically means the tax agency couldn’t deposit your tax refund as requested. That’s often due to missing or mismatched bank account details.
But this year, volume is part of the story.
As Kiplinger has reported, the federal government, including the IRS, is phasing out paper checks and steering more payments toward direct deposit. As a result, hundreds of thousands of taxpayers are being prompted to review or fix their banking information.
So, in recent months, there has been a significant surge in the number of legitimate CP53E letters issued by the IRS.
- Congressional data indicate that 1.4 million CP53E notices have been issued as of March 2026, amid the direct deposit push.
- As mentioned, this volume stems from IRS efforts to reduce paper checks, which take longer to process (typically 6-8 weeks, compared with a few days for electronic payments).
- The Taxpayer Advocate Service reports that direct deposit issues affect roughly 5% of filers each year, but the shift to paper checks has affected the number of notices sent this year.
That increase, and reports that some people have received notices sent in error, have raised concerns among taxpayers who may be unsure about the authenticity of the communications they receive purporting to be from the IRS.
What is an IRS CP53E notice?
As mentioned, the IRS typically sends a CP53E notice when the agency can’t deposit your tax refund due to missing, outdated, or mismatched bank details on file.
If your letter is legitimate, it usually indicates a processing issue with your refund — not a penalty or IRS audit.
In most cases:
- Your refund is temporarily on hold (usually approximately 21 days until you provide corrected information via your official IRS account).
- The IRS needs corrected or confirmed deposit details.
- You’ll have time to respond.
If you don’t take action, the IRS may still eventually send a paper check. It just may take some time, likely about 6 weeks, according to the agency.
How to spot a fake IRS letter: Red flags to consider
Here are some things to look at closely if you receive a letter that you’re not sure is real.
Be wary if the letter you receive asks for sensitive personal or banking information.
This might include your full Social Security number, bank login credentials, or detailed account information, or direct you to click a third-party link or scan an unfamiliar QR code. (Avoid scanning those codes in an unverified letter.)
You’ll also want to be cautious if the letter’s tone is urgent or threatening.
While legitimate IRS letters can be daunting, they usually should not rely on overly panic-driven language. And in the case of refund direct deposit notices, since you typically have roughly 30 days to respond, you will still likely receive a paper refund check if you don’t. So, panic language could be a red flag.
Keep in mind: The IRS generally doesn’t ask for sensitive data in unsolicited correspondence. Instead, a legitimate notice will typically direct you to log into your official IRS account via the official IRS website, not through a third-party or otherwise unfamiliar link.
Another thing to consider is whether the letter’s details match your tax situation.
Some taxpayers have reported receiving notices about refunds they weren’t expecting or about returns for which they are not due a refund.
That kind of mismatch doesn’t always mean fraud is involved, but it’s a signal to pause and verify before acting.
How to verify your CP53E notice and respond
If you receive a CP53E notice, the safest course is to go directly to the IRS website by entering the official IRS URL in your browser. From there:
- Log in to your official IRS online account
- Check whether the notice appears
- You can also call the IRS using an official number
IRS refund status: Bottom line
According to IRS reporting, refunds run about 11% higher on average than last year. The average refund amount has hovered around $3,400, most likely due to changes in the Trump/GOP tax and spending bill enacted last year.
Recent polls suggest that many plan to use that money to pay down debt or cover essentials.
Overall? If a letter that looks like it’s from the IRS asks you to share sensitive information, click on unfamiliar or third-party links, or act immediately, take a step back and verify it first.
And if your notice is legitimate and you need to track your tax refund after completing the direct deposit process, the IRS says to allow 2-5 days for your refund information to update online. From there, you can use the Where’s My Refund tool to check your refund status.
