Real tax refund checks have specific physical features you can verify without calling anyone

A real IRS refund check has a Treasury Department watermark visible when you hold it to light, the words "United States of America" printed across the top in a security pattern, and a routing number that matches a real Federal Reserve bank. The check number itself follows a specific format tied to the IRS processing center that issued it. If any of these elements are missing, blurry, or don't match what you see on the IRS website, the check is counterfeit.

The fastest way to verify is to look at the check itself before you deposit it. Counterfeit checks often have printing that looks slightly off—colors that don't quite match official samples, text that appears fuzzy, or security features that are clearly photocopied rather than printed. You can compare your check directly to images on the IRS website or the Bureau of Engraving and Printing website, both of which show what a legitimate Treasury check looks like.

If you're uncertain after inspecting the physical check, you can contact the IRS directly at 1-800-829-1040 to confirm whether a refund was issued to you. Have your Social Security number, filing status, and the check amount ready. The IRS will tell you whether they sent a check, when it was mailed, and what the check number should be. Do not deposit a check until you've confirmed it with the IRS.

Key Takeaways

  • Real IRS refund checks have a visible watermark when held to light and security printing that feels slightly raised to the touch, not flat like a photocopy.
  • The routing number on the check should belong to a Federal Reserve bank, which you can verify using the Federal Reserve's routing number database.
  • The IRS can confirm within minutes whether they issued a check to you, what the check number is, and when it was mailed.
  • Counterfeit checks often have printing that looks slightly blurry, colors that don't match official samples, or security features that appear to be photocopied.
  • Never deposit a check you're unsure about—depositing a counterfeit check can result in overdraft fees and potential fraud liability.

What to look for on the physical check itself

Hold the check up to a light source. A real Treasury check has a watermark that reads "The United States of America" and is visible from both sides of the paper. The watermark should appear as a faint image, not printed on top of the paper. If you see no watermark or if it looks like it was printed on, the check is fake.

Run your finger across the text and numbers on the check. Legitimate Treasury checks use intaglio printing, which creates a slightly raised texture you can feel. The text should feel slightly bumpy, not completely flat. Counterfeit checks are often photocopied or printed on a standard printer, so the surface will be smooth all over.

Look at the color and clarity of the printing. Real IRS checks use specific ink colors and patterns. The background should have a subtle security pattern, and the colors should be consistent and sharp. If the colors look washed out, the text appears fuzzy, or the security pattern looks like it was scanned and reprinted, these are signs of counterfeiting.

Verify the routing number and check number format

The routing number appears in the bottom left corner of the check, printed in a special magnetic ink character recognition (MICR) format. This nine-digit number identifies which Federal Reserve bank the check is drawn on. You can search any routing number in the Federal Reserve's routing number database at fedach.frb.org. If the routing number doesn't exist in that database or belongs to a bank rather than a Federal Reserve bank, the check is counterfeit.

The check number appears in two places: the bottom right corner and the top right corner. IRS refund checks follow a specific numbering sequence based on the processing center that issued them. The number should be eight digits long. If the check number is missing from either location, appears in a different format, or doesn't match the format shown on IRS examples, this is a red flag.

The account number (the long string of digits in the middle of the bottom line) should be present and complete. On a real check, this number should be clearly printed in MICR format. If it's missing, incomplete, or printed in regular text rather than MICR format, the check is not legitimate.

Compare your check to official IRS samples

The IRS publishes images of legitimate refund checks on their website. Go to irs.gov and search for "refund check images" or "what does an IRS check look like." The official samples show the exact layout, colors, security features, and text formatting of a real check. Place your check next to these images and compare them side by side.

Pay attention to the position of elements on the page. The routing number, account number, and check number should all be in the exact same positions as shown in the official samples. If your check has these elements in different locations or if the overall layout looks different, it may be counterfeit.

The Bureau of Engraving and Printing also maintains detailed information about Treasury check security features on their website. This resource shows close-up images of security elements like the watermark, the security threads, and the intaglio printing. If your check is missing any of these features or if they look different from the official images, do not deposit it.

Contact the IRS to confirm before depositing

Call the IRS at 1-800-829-1040 during business hours (Monday through Friday, 7 a.m. to 7 p.m. your local time). Have ready your Social Security number, filing status (single, married filing jointly, etc.), and the amount shown on the check. The IRS representative will search their records and tell you whether they issued a refund check to you.

If the IRS confirms they sent a check, ask for the check number and the date it was mailed. Compare this information to the check in your hand. The check number should match exactly, and the mailing date should be recent (within the last 30 days for a check that just arrived). If the information doesn't match, the check is counterfeit.

If the IRS has no record of sending you a check, or if the check number and mailing date don't match their records, do not deposit the check. Instead, contact your local police department's non-emergency line and report it as a potential fraud attempt. Keep the check as evidence.

What happens if you deposit a counterfeit check

If you deposit a counterfeit check, your bank will eventually discover it during the clearing process, which can take several days to two weeks. When the check is rejected, your bank will reverse the deposit and charge you an overdraft fee (typically $25 to $35) if the funds were already withdrawn. You may also face additional fees if the reversal causes other checks or transactions to bounce.

In some cases, the bank may hold you liable for the full amount of the counterfeit check, even if you deposited it in good faith. This is because federal law treats the depositor as responsible for verifying the check's authenticity. If you knowingly deposited a counterfeit check or if you deposited multiple counterfeit checks, you could face criminal charges for fraud.

If you suspect you've deposited a counterfeit check, contact your bank when ready and explain the situation. Report the check to the IRS and to your local police department. Keep all documentation, including the check itself, bank statements, and any correspondence with the IRS or your bank.

Common signs of a counterfeit refund check

Counterfeit checks often arrive in unexpected ways. A real IRS refund check comes by mail only—the IRS does not send checks by email, text message, or through a third-party service. If you received a check through any method other than the postal service, or if you received an email or text directing you to claim a refund, this is a scam.

The check may have been mailed to an address you didn't provide to the IRS. Real refund checks are mailed to the address on your tax return. If the envelope is addressed to you but at a different address, or if it's addressed to a variation of your name that you don't use, this is suspicious.

The amount on the check may not match what you expected. If you filed a return showing a refund of $800 but received a check for $2,500, or if you received a check when you expected to owe taxes, verify with the IRS before depositing. Scammers sometimes send checks for amounts that seem plausible but don't match your actual return.

Frequently Asked Questions

Can I deposit the check and then verify it with the IRS?

No. Once you deposit a check, you become liable for it if it's counterfeit. Your bank will reverse the deposit and charge you fees, and you may face fraud liability. Always verify with the IRS before depositing, even if it takes an extra day.

What if the IRS says they sent a check but I never received it?

Contact the IRS and report the check as lost or stolen. They can issue a replacement check or deposit the refund directly to your bank account if you provide banking information. Do not deposit a check that the IRS says they already issued if you didn't receive it yourself.

How long does it take the IRS to mail a refund check?

The IRS typically mails refund checks within 21 days of processing your return, though this varies depending on the processing center and the time of year. If you filed electronically and chose direct deposit, the refund is usually deposited within 21 days. If you chose a mailed check, add 5 to 7 business days for postal delivery.

What should I do if I think I received a check that's not mine?

Do not deposit it. Contact the IRS with the check number and the name on the check. They will tell you who the check was issued to and may be able to redirect it. You can also return the check to the IRS by mail with a note explaining that you received it in error.

Is there a way to track my refund check before it arrives?

Yes. Use the IRS "Where's My Refund?" tool on irs.gov. Enter your Social Security number, filing status, and the refund amount. The tool will tell you whether your refund has been processed, whether it was mailed as a check or deposited directly, and the expected delivery date. If the tool shows no refund was issued, any check you receive is counterfeit.
