Real tax refund checks have specific features that are hard to copy

A real tax refund check from the IRS (Internal Revenue Service) has security features printed directly into the paper and ink. Scammers often send checks that look close enough at first glance but fall apart under inspection. The difference between a real check and a fake one usually shows up in the paper quality, the printing, the routing numbers, and the way the check is signed.

Fake checks are common because they work fast — someone receives what looks like a refund, deposits it, and by the time the bank discovers it is counterfeit, the scammer has already taken the money. You can protect yourself by knowing what to look for before you deposit anything.

Key Takeaways

  • Real IRS refund checks are printed on security paper with a watermark and color-shifting ink that changes appearance when you tilt it.
  • The check number, routing number, and account number on a real IRS check follow specific formats that you can verify against IRS records.
  • The IRS never sends refunds to a third party or to an address different from the one on your tax return without written notice first.
  • If you are unsure whether a check is real, contact the IRS directly at 1-800-829-1040 or visit irs.gov before depositing it.

What the paper and printing should look like

Real IRS refund checks are printed on special security paper that has a watermark — a faint image visible when you hold the check up to light. The watermark shows the word "TREASURY" repeated across the paper. If you hold the check at an angle, you should see color-shifting ink on the check number in the bottom right corner; the color changes from green to gold as you tilt it.

The paper itself feels slightly textured and is heavier than regular printer paper. Fake checks are often printed on standard paper or thin cardstock, which feels smooth and flimsy by comparison. Run your finger across the surface — a real check has a slight grain to it.

The printing on a real check is crisp and even, with no smudges or blurry edges. The text and numbers are perfectly aligned. If the printing looks fuzzy, if colors are slightly off, or if the lines are not straight, the check is likely counterfeit.

The numbers that identify the check

Every real check has three sets of numbers at the bottom: the routing number (nine digits on the left), the account number (in the middle), and the check number (on the right). On a real IRS refund check, the routing number is always 021000021, which is the routing number for the U.S. Department of the Treasury. The account number and check number vary, but they follow specific patterns.

You can verify the routing number by visiting the Federal Reserve's routing number database at frbservices.org or by calling the IRS directly. If the routing number on your check is anything other than 021000021, it is not from the IRS. Scammers sometimes use real routing numbers from other banks to make the check look legitimate, so always check this number first.

The check number should be printed in two places: once in the bottom right corner and once in the top right corner. On a fake check, these numbers sometimes do not match, or they are printed in slightly different fonts or sizes.

Who the check is made out to and signed by

A real IRS refund check is made out to you — the person whose name appears on the tax return. It is never made out to a tax preparer, a financial advisor, or anyone else, even if that person helped you file. If you receive a check made out to someone other than yourself, do not deposit it.

The check is signed by the Secretary of the Treasury or a Treasury official whose name is printed on the check. The signature is always the same — it is a printed signature, not a handwritten one. If the signature looks different from other IRS checks you have received, or if it appears to be handwritten, the check is fake.

The address on the check should match the address you provided on your tax return. If the address is different, contact the IRS before depositing the check. The IRS does not mail refunds to addresses other than the one on file without sending you a notice first.

Red flags that mean the check is not real

Stop and verify the check if any of these things are true: the paper feels thin or smooth, the watermark is missing or unclear, the color-shifting ink is not present, the routing number is not 021000021, the check is made out to someone other than you, the signature looks different from other IRS checks, or the address does not match your tax return.

Also be suspicious if the check arrived unexpectedly — you did not file a return, you did not request a refund, or the amount seems too large. The IRS does not send refunds without a tax return on file. If someone contacted you by phone, email, or text to tell you a refund was coming, that is a scam. The IRS does not contact people about refunds by phone or email.

If the check came with a letter asking you to cash it quickly, deposit it into a specific account, or send part of the money somewhere else, it is definitely fake. The IRS never asks you to do any of these things.

What to do if you think the check is counterfeit

Do not deposit the check. Instead, contact the IRS directly at 1-800-829-1040 to report it and ask them to verify whether it is real. Have the check in front of you when you call so you can read the numbers and details to the IRS agent. They can tell you within minutes whether the check is legitimate.

If the IRS confirms the check is fake, do not throw it away — keep it as evidence. You can report the counterfeit check to the U.S. Secret Service, which investigates counterfeiting crimes, by visiting secretservice.gov or calling your local Secret Service field office. You can also report it to the FBI's Internet Crime Complaint Center at ic3.gov if you received the check through email or online.

If you have already deposited a fake check, contact your bank when ready and tell them it is counterfeit. Your bank can stop the check from clearing and may be able to reverse any charges. Report the fraud to the Federal Trade Commission at reportfraud.ftc.gov as well.

How to verify a check directly with the IRS

The safest way to know for certain is to call the IRS yourself. Have your Social Security number, the check number, the routing number, and the amount ready. The IRS can tell you whether they issued a refund in that amount to your name and whether the check number matches their records.

You can also visit irs.gov and use the "Where's My Refund?" tool to see the status of any refund you are expecting. This tool shows you the date the refund was issued and the method it was sent (check, direct deposit, or debit card). If the tool shows your refund was issued by direct deposit but you received a check, the check is fake.

Frequently Asked Questions

Can a fake check clear my bank account?

Yes. A fake check can clear initially, meaning the money appears in your account. But banks discover counterfeits within days or weeks, and when they do, they reverse the deposit and charge your account. If you have already spent the money, you will owe your bank the full amount.

What if the check looks real but the amount is wrong?

Contact the IRS before depositing it. Use the "Where's My Refund?" tool on irs.gov or call 1-800-829-1040 to confirm the exact amount of your refund. If the check amount does not match, do not deposit it.

Is it illegal to deposit a fake check if I did not know it was fake?

No, depositing a counterfeit check unknowingly is not a crime. But if you knowingly deposit a fake check or help someone else do so, that is fraud. If you discover the check is fake after depositing it, contact your bank and the IRS right away to show you acted in good faith.

Why would someone send me a fake refund check?

Scammers send fake checks to steal your identity or your money. They may have obtained your personal information from a data breach or phishing email. Once you deposit the check, they may contact you asking you to wire part of the money back, claiming it was sent by mistake. By then, the check has bounced and you have lost money.

What if I already cashed a fake check at a check-cashing store?

Contact the check-cashing store when ready and tell them the check is counterfeit. They may be able to stop payment. Also contact your bank if you deposited the money into an account, and report the fraud to the FTC at reportfraud.ftc.gov and the IRS at 1-800-829-1040.
