If a CP53E notice from the IRS just landed in your mailbox, you may be wondering whether it’s real or the work of a scammer. The Taxpayer Advocate Service (TAS), the independent watchdog inside the IRS, has published guidance to help taxpayers answer exactly that question.
The short version: a CP53E notice is a legitimate type of IRS correspondence. But because scammers routinely imitate official tax letters, TAS urges recipients to slow down and verify before acting on anything the notice asks them to do.
Below is what the IRS CP53E notice signals, how to confirm it’s genuine, and the steps to take if you suspect fraud.
What is a CP53E notice from the IRS?
A CP53E is one of the IRS’s coded notices sent through the mail. According to the Taxpayer Advocate Service, notices in this family relate to a refund that could not be sent to your bank account by direct deposit, so the IRS is arranging to mail a paper check instead and explaining the delay.

If the wording on your notice differs from a general description, follow what the actual IRS letter and the official IRS website say about that notice number.
How do I know if the CP53E notice is a scam?
Scammers copy IRS branding and notice codes to trick people into handing over money or personal data. The Taxpayer Advocate Service points to a few reliable ways to separate a real IRS notice from a fake one:
- The IRS contacts you by mail first. The agency does not open contact about a notice like this with a threatening phone call, text, or email demanding immediate payment.
- No demand for gift cards or wire transfers. The real IRS will never ask you to pay with gift cards, prepaid debit cards, cryptocurrency, or a wire transfer.
- No pressure to hand over passwords or PINs. A genuine notice will not ask you to confirm your full Social Security number, bank passwords, or account PINs by replying to a link or phone number printed by a stranger.
- Check the notice number and language. A real CP53E will carry the CP53E code and reference your tax year. Misspellings, odd formatting, or a code that doesn’t match anything on the IRS site are warning signs.
Because impersonation is common, treat any surprise link, QR code, or callback number with caution until you have verified it independently.
How do I verify a CP53E notice is real?
The safest move is to confirm the notice through official IRS channels rather than any contact information the suspicious message provides. To verify a CP53E notice:
- Look up the notice on IRS.gov. Go directly to the IRS website and search the notice number to read what a CP53E means and what it typically asks of you.
- Check your IRS online account. Log in through IRS.gov to see whether the notice and any refund or check activity actually appear on your record.
- Call the IRS using a number from IRS.gov. Do not rely on a phone number printed only on a letter you’re unsure about. Use the official contact numbers listed on the IRS site.
For example, if your CP53E says a direct deposit failed and a paper check is coming, you can log in to your IRS online account and confirm whether a refund is genuinely being reissued to your address. If nothing matches, that’s a strong signal the letter may be fraudulent.
What should I do if I think the notice is fake?
If the correspondence looks like an impersonation attempt, the Taxpayer Advocate Service and the IRS recommend reporting it rather than responding. Do not click links, call the numbers in the suspicious message, or send any payment or personal details.
- Don’t reply directly. Avoid engaging with the sender through the contact details in the questionable notice.
- Report suspected IRS impersonation. The IRS accepts reports of phishing and scam attempts; forward suspicious emails and report fraudulent contact through the channels listed on IRS.gov.
- Keep the evidence. Hold on to the notice, envelope, or message in case investigators need it.
Where can I get help with a CP53E notice?
If the notice turns out to be real but you can’t resolve the issue with the IRS, the Taxpayer Advocate Service exists for exactly that situation. TAS is an independent organization within the IRS that assists taxpayers facing financial hardship or delays they cannot fix through normal channels.
You can reach TAS through its website and find local office contacts there. When in doubt about any notice, verifying it through IRS.gov and your own IRS online account remains the most dependable way to protect yourself. Because a genuine CP53E notice is usually about a delayed refund rather than a demand for money, any letter pressuring you to pay fast should raise immediate suspicion.
