A letter shows up saying you owe money. A caller says a warrant is out for your arrest. A text says your refund is on hold. Your first thought is the right one. Is this really the IRS, or is someone trying to rob me through an IRS tax scam?
Most of the time, you can tell in a few minutes. The real IRS follows strict rules. Scammers break those rules on purpose, and every time they do, they hand you a way to catch them.
I’ve spent more than 15 years representing taxpayers in federal tax matters. I’ve argued with real IRS agents, sat across from revenue officers, and taken cases to Tax Court. I know how the agency actually works, and I know how far a scam has to stray from that to fool you. Here’s how to check any IRS contact, spot a fake, and report it fast.
How the Real IRS Actually Contacts You
Start with the rulebook the real IRS lives by. When the agency wants something, the first contact almost always arrives as a letter in the mail. Not a call. Not a text. A letter, sent to your address, on official stationery, with a notice number you can look up.
The IRS will never do any of these on a first contact.
- Call or text you before it has mailed you a written notice.
- Demand that you pay right now, over the phone, with no chance to review or appeal.
- Threaten to send police, revoke your license, or have you deported.
- Tell you to pay with gift cards, prepaid debit cards, cryptocurrency, or a wire transfer.
- Ask for your card number or bank login over the phone.
- Reach out first by email, text, or social media direct message.
When you genuinely owe money, the mailed notice spells out the tax year, the amount, the reason, and your right to respond. You get time. You get an appeal. Not sure what a real notice is asking for? Our breakdown of how IRS certified letters work walks through the common types. Scammers skip all of it because the whole point is to panic you before you think.
How to Tell a Fake IRS Letter From a Real One
Paper scams are climbing. As the Treasury moves federal payments to electronic methods, con artists are mailing letters dressed up to look official. Some copy the IRS eagle. Some invent an office name like “Tax Processing Unit.” So how do you check?
Find the notice number first. Every real IRS letter carries a CP or LTR number, usually in the top right or bottom right corner. Real example numbers include CP14, CP2000, and CP504. No notice number, or a vague “case number” instead? Treat it as suspect.
Then read the tone. A real notice states the tax year, explains the issue, and tells you how to respond or appeal. A fake one leans on fear. Watch for “final notice,” “immediate levy,” or “pay within 24 hours.” Those phrases do the scammer’s work, which is to rush you.
Check the payment instructions too. The real IRS routes payments to the U.S. Treasury, never to a person or a private account, and never to a gift card. And if a letter demands you “verify” your bank details or identity through a link or a strange phone number, slow down. Some real notices do ask you to confirm your identity, like the CP03 identity verification notice. Even then, you confirm it through your own IRS account or a number you look up yourself, not one on the letter.
The IRS Tax Scams Hitting Taxpayers in 2026
The IRS updates its annual Dirty Dozen list of tax scams every year, and phishing and smishing lead it again. Here are the patterns showing up most this year, with the tells that give each one away.
Text and email phishing with QR codes. A message poses as the IRS and asks you to “verify” your account or claim a refund. AI now writes clean, logo-perfect copy, so the old typo tell is gone. The message often hides the fake link behind a QR code to dodge spam filters. The IRS doesn’t start contact by text or email, full stop.
AI voice cloning on the phone. Scammers spoof the caller ID to read “IRS” and use cloned, natural-sounding voices. They quote a small balance, usually under $2,000, because it sounds believable. Then they push for a gift card or wire before you can hang up and check.
Fake “update your direct deposit” notices. The Treasury is phasing out paper refund checks under Executive Order 14247, which took effect for refunds after September 30, 2025. Scammers seized the moment. They send messages telling you to “update your banking info for your refund.” The IRS collects that information through your return and your online account, not a text link.
Unclaimed refund mail. A letter or postcard says you have an unclaimed refund waiting and asks for personal details to release it. Real refund questions get answered in your IRS account, not through a form you mail to a stranger.
Social media refund “hacks.” Viral videos promise secret credits, from fake Fuel Tax Credits to invented business write-offs. Following them draws an audit, penalties, and sometimes criminal tax fraud charges. The refund fantasy isn’t worth the record.
Ghost preparers. A preparer does your return but won’t sign it. That’s illegal. Real preparers sign every return they touch. Ghosts inflate refunds, route the money to their own account, and vanish when the IRS comes asking.
Got a Check or Deposit You Didn’t Expect?
A surprise deposit or a government check throws a lot of people. Is it real, or is it bait? Usually it’s real, and the label on your bank statement tells the story.
A deposit marked IRS TREAS 310 is a standard IRS refund or credit sent by direct deposit. A deposit marked TCS TREAS 449 is also a federal tax refund, but it ran through the Treasury’s Bureau of the Fiscal Service offset program. The 449 code means part of your refund was held back to cover a past-due debt, like student loans or child support. If that happens, the Bureau mails you a notice explaining the offset.
A paper check from the “U.S. Department of the Treasury, Bureau of the Fiscal Service” is the standard look for a legitimate federal check. That said, fake Treasury checks do circulate. Before you deposit an unexpected one, confirm the payment inside your own IRS or Treasury account rather than trusting the check alone.
How to Confirm Whether You Actually Owe the IRS
Suppose the contact rattled you and now you’re wondering. What if I really do owe? Three checks settle it.
Set up your own IRS Online Account at IRS.gov and log in. It shows your real balance, your payment history, and copies of the notices the IRS has actually sent you. A threatening call about thousands you owe, next to an account that reads zero, is your answer.
Call the IRS yourself using a number you looked up, never a callback number from a suspicious message. Individuals reach the IRS at 1-800-829-1040. If a letter references a revenue officer, you can also verify a registered IRS revenue officer before you say a word.
Read your mail. Real collection comes with mailed notices that name the tax year, the amount, and your appeal rights. Calls and texts with no matching letter? Almost always a scam.
How to Report an IRS Scam
Reporting a scam protects the next person who picks up the phone. The steps are quick.
For a scam phone call, don’t share a thing. Hang up. Write down the number, the time, and any name or badge number the caller gave. Then report it to the Treasury Inspector General for Tax Administration through TIGTA’s impersonation scam reporting form (or by phone at 1-800-366-4484). File a second report with the FTC.
For a phishing email, don’t click, don’t reply. Forward the whole message to [email protected], then delete it. The IRS explains the full process on its report phishing page.
For a smishing text, don’t tap the link. Screenshot the message with the sender’s number. Forward the text to SPAM (7726), then report it to TIGTA and the FTC the same way you would a call.
What to Do If You Already Paid a Scammer
Sent money before the doubt set in? Move fast, because speed decides how much you get back.
Paid by wire? Call the wire company right away and ask for a recall. Western Union is 1-800-325-6000. MoneyGram is 1-800-926-9400.
Paid by gift card? Call the card’s issuer with the number and receipt and ask them to freeze the balance. Some companies can stop unused funds.
Paid by card? Call your bank or card issuer, report the charge as fraud, and ask for a new card number. Most issuers cover fraud with zero liability.
Then protect the rest. File a police report, and report the loss to TIGTA and the FBI’s Internet Crime Complaint Center. Place a fraud alert with a credit bureau. Ask the IRS for an Identity Protection PIN so no one can file a return in your name.
Common Questions About IRS Scams and Fake Notices
Is irs.gov/account a legitimate site?
Yes. IRS.gov is the official site, and your Online Account at IRS.gov is the real, free place to check your balance and notices. Set it up yourself. Never pay a third party who offers to create the account for you, because all they want is your Social Security number and bank details.
Why did I get a check from the Bureau of the Fiscal Service?
The Bureau of the Fiscal Service is the Treasury office that issues most federal payments, including IRS tax refunds. A check or deposit from it is usually a legitimate refund. If the amount surprises you, confirm it in your IRS Online Account before you rely on it.
What does a TCS TREAS 449 or IRS TREAS 310 deposit mean?
Both are federal tax refunds. IRS TREAS 310 is a standard direct-deposit refund. TCS TREAS 449 ran through the Treasury offset program, which means part of the refund may have been applied to a past-due debt. The Bureau mails a notice when an offset happens.
Is the phone number 800-830-5084 a real IRS number?
Yes. 1-800-830-5084 is the IRS Identity Verification line. The IRS gives you that number in a letter (a 5071C) when it needs to confirm your identity before processing your return. Only call it if you got that letter, and confirm the letter is real in your IRS account first.
Does the IRS ever contact you by text or email?
No, not to start contact about a bill or a refund. The IRS opens with mailed letters. Any text or email claiming to be a first contact from the IRS is a scam, even when it looks polished.
I got a letter saying I owe money. How do I know it’s real?
Look for a CP or LTR notice number, and check that it names your tax year and appeal rights. Then confirm the same notice shows up in your IRS Online Account. If the letter has no notice number and pushes gift cards or a 24-hour deadline, it’s fake.
When the Problem Is Real, Not a Scam
Sometimes the letter checks out and the balance is real. A genuine IRS collection action, a wage garnishment, a bank levy, or a tax lien, follows the rules but hits just as hard. The difference is that you have real options, and real deadlines to use them.
Installment agreements, Offers in Compromise, Currently Not Collectible status, penalty abatement, innocent spouse relief. None of these are automatic, and what you say to the IRS shapes what you qualify for. That’s where the wrong move gets expensive.
