To tell if a tax refund check is real, check for security features like the "U.S. TREASURY" watermark when held to light, a Treasury Seal with bleeding ink (turns red with moisture), and UV patterns visible under black light; also, verify the check number and amount via the Bureau of the Fiscal Service Treasury Check Verification System (TCVS) (tcvs.fiscal.treasury.gov) and confirm the amount matches your actual refund. If it looks suspicious, contact the IRS directly or visit an IRS office for verification, as scammers often send fake checks with demands for money back.

How to tell if someone is scamming you with a check?

You know someone's scamming you with a check if they send a check for too much money, ask you to send some back or to a third party (like for "fees"), or if the check itself has physical red flags like smudged ink, flimsy paper, mismatched numbers (top vs. bottom), or incorrect bank info, often coupled with high-pressure tactics or a story about overpayment for a job or prize. The check often looks real but fails security checks because banks take weeks to discover the fraud, by which time you've sent your own money.
 

What are the red flags of a fake check?

Check fraud red flags include fake check scams (overpayment/refund requests, urgency, vague stories), physical/printing issues (low-quality paper, odd fonts, missing security features like watermarks), altered checks (mismatched handwriting, smudges, overwritten payee/amount), and unusual account activity (unexpected withdrawals, new accounts used for quick deposits/transfers, missing checks). Be suspicious of requests for immediate action or personal info, and scrutinize unfamiliar checks, especially those from unknown senders or for unusual amounts. 

How can I know a fake check?

To tell if a check is fake, look for poor print quality (smearing ink, blurry logos, mismatched fonts), inconsistent information (misspelled names/banks, mismatched numerical/written amounts), missing security features (watermarks, microprinting), odd paper (thin, shiny), and unusual MICR numbers at the bottom; genuine checks have sharp text, a matte finish, and security features, while fakes often feel off and have glaring errors, especially when from an unfamiliar source or part of a suspicious request.

Why did I get a random tax refund check?

An unexpected tax refund usually means you overpaid taxes through withholding or estimated payments, or you qualified for a refundable tax credit, but sometimes it's an IRS error or part of a scam, so you should check your tax account on the IRS website to verify the source and amount. Common reasons include incorrect W-4 settings leading to excess withholding, self-employed individuals overestimating taxes, or receiving credits like the EITC or Child Tax Credit.

Do banks verify checks before depositing?

Do banks usually refund scammed money?

Yes, banks can refund scammed money, but it depends heavily on the payment method, how quickly you report it, and if the transaction was truly "unauthorized" (someone stole your login) versus you being tricked into sending it (authorized push payment).
