If you deposit fake money in an ATM, the bank confiscates the bills, reverses any credit it gave your account, and reports the notes to the U.S. Secret Service. Whether anything worse happens turns almost entirely on what you knew. An honest mistake costs you the face value of the cash and some uncomfortable questions. Knowingly passing counterfeit bills is a federal felony under 18 U.S.C. § 472, punishable by up to 20 years in prison and a fine of up to $250,000.
What the Bank Does With the Bills
The counterfeit notes are gone the moment they’re identified. You don’t get them back, and you don’t get credited for their face value. From the bank’s perspective, you deposited worthless paper.
The bank then submits each suspected counterfeit note to the Secret Service using Form SSF 1604, which goes to the agency’s Counterfeit Currency Processing Facility. The form records the denomination, serial number, date of deposit, and identifying information about the person who deposited the note. When the bank has useful details about who originally passed the bill, it may instead report directly to a local Secret Service field office or police department so agents can follow up on investigative leads.1United States Secret Service. Reporting Suspected Counterfeit Currency to the United States Secret Service
On top of the Secret Service referral, the bank may file a Suspicious Activity Report with the Financial Crimes Enforcement Network if the transaction involves $5,000 or more and the bank suspects illegal activity. Counterfeit instruments are a specifically listed category of suspicious activity that can trigger this filing.2Financial Crimes Enforcement Network.

What Happens to Your Account Balance
This is where people get caught off guard. If the ATM provisionally credits your account before the counterfeit is caught during back-end processing, the bank will reverse that credit. Federal regulations preserve the bank’s right to charge back your account for any deposited item that turns out to be uncollectible.3eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks
If you’ve already spent some of those provisionally credited funds, the reversal can push your account into the negative. The Consumer Financial Protection Bureau has confirmed that banks can take the money back even after making it available for withdrawal, and if that puts you in overdraft, you’re responsible for the resulting balance and any fees.4Consumer Financial Protection Bureau. Fraudulent Check Deposit and Overdraft Fees
Beyond the immediate financial hit, a counterfeit deposit can damage your standing with the bank. Repeated incidents or large amounts of counterfeit currency may lead the bank to close your account entirely. A Suspicious Activity Report, once filed, becomes part of a federal database that other financial institutions can access when evaluating whether to do business with you.
Federal Criminal Exposure
Knowingly depositing counterfeit currency is a federal felony under 18 U.S.C. § 472, which criminalizes passing or attempting to pass counterfeit U.S. obligations with intent to defraud. The maximum penalty is 20 years in federal prison, a fine of up to $250,000, or both.5Office of the Law Revision Counsel. 18 USC 472 – Uttering Counterfeit Obligations or Securities6Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
A separate statute, 18 U.S.C. § 473, targets anyone who buys, sells, exchanges, or receives counterfeit currency knowing it’s fake and intending for it to be used as genuine. This charge carries the same maximum penalties. Prosecutors sometimes use it when someone obtains counterfeit bills at a discount with plans to pass them at face value.7Office of the Law Revision Counsel. 18 USC 473 – Dealing in Counterfeit Obligations or Securities
The actual sentence in any given case depends on the amount of counterfeit money involved, the defendant’s criminal history, and the federal sentencing guidelines. Someone caught depositing a single fake $20 faces a very different situation than someone running hundreds of counterfeit notes through multiple accounts.
Why Intent Decides Whether You’re Charged
Both § 472 and § 473 require prosecutors to prove “intent to defraud.” The government must show you knew the bills were counterfeit and deliberately tried to pass them off as real. Without that proof, there’s no federal crime.5Office of the Law Revision Counsel. 18 USC 472 – Uttering Counterfeit Obligations or Securities
If you genuinely didn’t know the money was fake, you can’t be convicted. But “I didn’t know” isn’t a magic phrase that ends the investigation. The Secret Service will examine the circumstances: how many counterfeit bills were involved, where you say you got them, whether you have a pattern of similar deposits, and what you told bank staff. A single counterfeit $50 mixed into a stack of real bills paints a different picture than twenty fake $100s deposited across three branches in one afternoon.
Investigators also look at the quality of the counterfeits. Someone who receives a decent fake as change from a gas station is in a very different position than someone depositing obviously fake bills printed on copier paper. The sophistication of the forgery can suggest whether a reasonable person would have noticed something was wrong.
What to Do If You Realize You Deposited Fake Bills
Contact your bank as soon as you realize what may have happened. Explain the situation honestly, including where you got the cash and how many bills you’re concerned about. Volunteering this information promptly works in your favor if investigators later need to evaluate your intent.
Don’t try to spend or deposit any other bills from the same source. If you have additional suspicious cash, set it aside. Trying to pass it along once you have reason to believe it’s fake crosses the line from innocent mistake to federal crime.
If the Secret Service or local law enforcement contacts you, consider speaking with a criminal defense attorney before your interview. You’re not required to answer questions beyond identifying yourself, and having counsel present protects you from inadvertently making statements that could be misinterpreted as evidence of knowledge or intent. Cooperation generally helps, but cooperation with legal guidance helps more.
Keep any ATM receipts, bank statements, or other records showing the deposit. If the cash came from a specific transaction, such as a private sale or payment for services, document everything you can about that exchange. That evidence supports your account of how you came to possess the bills.
Checking Cash Before You Deposit It
A few seconds of inspection can save you from losing money and dealing with an investigation. The Secret Service recommends checking these features on any bill $5 or higher:
- Paper texture. Genuine U.S. currency is printed on a blend of 75% cotton and 25% linen with small red and blue fibers embedded throughout. Counterfeits printed on standard paper feel noticeably different.
- Watermark. Hold the bill up to a light. Bills from the current design series show a faint portrait watermark that matches the printed portrait on the front.
- Security thread. A thin embedded strip runs vertically through every denomination except $1 and $2 bills. It’s visible against light, and each denomination’s thread sits in a different position and glows a specific color under ultraviolet light: blue for $5, orange for $10, green for $20, yellow for $50, and pink for $100.
- Color-shifting ink. On $10 bills and higher, the numeral in the lower right corner shifts from copper to green when you tilt the note.
Modern ATMs run deposited notes through ultraviolet, infrared, and magnetic ink checks, and banks run a second authentication pass through commercial counting machines before funds settle. Most counterfeits that slip past the machine are caught during that back-end processing, which is why a bad bill you deposited yesterday can still produce a reversed credit, a confiscated note, and a Secret Service report tomorrow.
