Yes, you can dispute a charge on your checking account, and your bank has a legal obligation to investigate
When you spot a charge you didn't make or don't recognize on your checking account, you have the right to dispute it. Your bank must take the dispute seriously and investigate within a set timeframe. The process is called a chargeback or dispute claim, depending on whether the charge came from a debit card transaction or an ACH transfer. Your bank will either reverse the charge while they investigate, or they'll tell you upfront that they won't — but they must document their reason.
The speed of resolution depends on the type of transaction and whether your bank considers it a clear case of fraud or an error. A debit card charge you didn't authorize typically moves faster than a dispute over a check you wrote or an ACH payment you initiated but now regret. The bank's job is to determine whether the charge was actually unauthorized, not whether you straightforward changed your mind about a purchase.
Key Takeaways
- You must report an unauthorized charge to your bank within 60 days of the statement date it appears on, or you lose your right to dispute it.
- For debit card fraud, your bank must reverse the charge while investigating if you report it within two business days; after that, your protection drops significantly.
- The bank will contact the merchant or the other financial institution involved and ask them to prove the charge was authorized.
- If the bank finds the charge was unauthorized, they will credit your account; if they find it was authorized, you keep the charge and the dispute closes.
The difference between unauthorized charges and buyer's remorse
Banks distinguish between two situations: a charge you genuinely did not authorize, and a charge you authorized but now regret. Only the first one qualifies as a dispute your bank must investigate. If you ordered something online, received it, and now want your money back because you changed your mind, that is not a bank dispute — that is a return or refund issue between you and the merchant.
An unauthorized charge is one where someone else used your account number, card number, or routing number without your permission. It includes charges from a lost or stolen card, identity theft, a hacked online account, or a merchant who charged you twice by mistake. If you authorized the charge but the merchant failed to deliver the goods or service, or delivered something broken, your first step is to contact the merchant directly and request a refund. If the merchant refuses, then you can ask your bank to dispute it — but you will need to show evidence that you tried to resolve it with them first.
How to report the charge to your bank
Contact your bank as soon as you notice the unauthorized charge. You can call the customer service number on the back of your debit card, visit a branch in person, or use your bank's online banking portal or mobile app — most banks now have a "Report Fraud" or "Dispute a Transaction" option in the app. Have your account number and the transaction details ready: the date of the charge, the amount, and the merchant name.
Tell the bank clearly that the charge is unauthorized and you did not make it. Do not say you "don't recognize" it or you're "not sure" — those words suggest you might be confused rather than certain it was fraud. The bank will ask you to confirm your recent legitimate transactions so they can see what you normally spend on and where. They may also ask whether anyone else has access to your card or account number.
After you report it, the bank will issue you a temporary debit card or a new card number while they investigate. You will still have access to your checking account, but your old card will be blocked. This usually happens within one to three business days.
What happens during the investigation
Once you report the charge, your bank enters a formal dispute process. For debit card transactions, the bank has 10 business days to investigate and decide whether to reverse the charge. For ACH transfers or other electronic payments, the timeline is typically 10 to 20 business days. During this time, the bank contacts the merchant or the other bank involved and asks them to provide proof that you authorized the charge — usually a signed receipt, an IP address match, or a confirmation email you received.
The merchant or other bank then has a set number of days to respond. If they cannot provide proof of authorization, the bank will reverse the charge and credit your account. If they do provide proof — for example, a receipt with your signature or a confirmation email from your account — the bank will close the dispute and the charge stays on your account. You will receive written notice of the decision, either by mail or through your online banking portal.
While the investigation is ongoing, the bank may place a temporary credit in your account so you are not out the money. This is not the same as a final decision. If the investigation concludes the charge was authorized, the bank will remove the temporary credit and you will owe the amount again.
The 60-day reporting important date and what it means
You must report an unauthorized charge within 60 days of the date it appears on your statement. This is a federal requirement under the Electronic Funds Transfer Act. If you wait longer than 60 days, your bank can refuse to investigate and you lose your right to dispute it. The 60 days starts from the date the statement is sent to you, not the date the charge occurred.
For example, if a charge appears on a statement dated March 15, you have until May 14 to report it. If you report it on May 15, the bank can legally refuse to open a dispute. Some banks may still investigate as a courtesy, but they are not required to. This is why checking your statements regularly — weekly or at least every two weeks — matters. The sooner you spot an unauthorized charge, the sooner you can report it and the sooner the investigation can begin.
Debit card fraud versus other types of unauthorized charges
Debit card fraud has stronger protections than other types of unauthorized charges. If you report a fraudulent debit card charge within two business days of discovering it, your liability is capped at $50. If you report it between two and 60 days, your liability can be up to $500. If you wait longer than 60 days, you may be liable for the entire amount.
Unauthorized ACH transfers and checks have different rules. For ACH transfers, you have 60 days to report, but your bank is not required to reverse the charge while investigating — they may ask you to wait for the investigation to conclude. For checks, if someone forged your signature or altered the amount, you have three years to report it, but you must notify the bank promptly or you may lose your right to dispute it. The bank's investigation timeline for checks is longer, often 30 to 45 days.
What to do if the bank denies your dispute
If the bank concludes the charge was authorized and closes the dispute against you, you have options. First, ask the bank for a detailed explanation in writing. They must tell you what evidence the merchant or other bank provided and why they found it credible. Read this carefully — sometimes the evidence is weak or the bank made an error in their analysis.
If you believe the bank made a mistake, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) or your state's banking regulator. You can also contact your state's attorney general's office. These agencies can investigate whether the bank followed the law correctly. You cannot force them to reverse the charge, but they can pressure the bank to reconsider if they find the investigation was flawed.
If the charge came from a merchant and you have evidence the merchant was fraudulent — for example, the business no longer exists or you have a police report — include that in your complaint. Some banks will reopen a dispute if you provide new evidence they did not have during the first investigation.
Preventing unauthorized charges in the future
While disputing a charge works, preventing fraud in the first place is easier. Check your statements at least every two weeks, not just once a month. Enable transaction alerts on your bank's app so you get a notification every time a charge is made — this lets you catch fraud within hours instead of days. Use a strong, unique password for your online banking account and change it every three months. Do not use the same password across multiple financial websites.
For online purchases, use a credit card instead of a debit card when possible — credit card fraud has stronger federal protections than debit card fraud. If you must use a debit card, use it only at merchants you trust and never at unfamiliar websites. For recurring charges like subscriptions, review them monthly and cancel anything you no longer use. Fraudsters often test stolen card numbers with small recurring charges that go unnoticed.
Frequently Asked Questions
How long does it take to get my money back after I dispute a charge?
For debit card fraud, the bank must decide within 10 business days. If they find the charge was unauthorized, they credit your account when ready. For ACH transfers and other electronic payments, the timeline is 10 to 20 business days. For checks, investigations can take 30 to 45 days. During the investigation, the bank may place a temporary credit in your account so you have access to the money while they verify.
What if I authorized the charge but the merchant never delivered the product?
Contact the merchant first and request a refund. If they refuse or do not respond within 30 days, then ask your bank to dispute it. You will need to show the bank that you tried to resolve it with the merchant — save emails, chat transcripts, or notes of phone calls. The bank will investigate, but they may side with the merchant if the merchant claims they delivered the item or if your purchase was final sale.
Can I dispute a charge if someone I know used my card without permission?
Yes. It does not matter whether the person is a family member, friend, or stranger — if you did not authorize the charge, it is unauthorized. Report it to your bank the same way you would report any other fraud. The bank will not pursue the person criminally, but they will reverse the charge if they find it was unauthorized. You may want to contact the police separately if the amount is large or if you believe the person committed identity theft.
What happens to my account while the dispute is being investigated?
Your account stays open and you can continue to use it. Your old debit card will be blocked and you will receive a new one. You can still write checks, set up automatic payments, and transfer money. If the bank places a temporary credit while investigating, that money is available to you when ready, though it may be removed if the investigation concludes the charge was authorized.
Can I dispute a charge more than once if the bank denies it the first time?
Not through your bank's dispute process — once they investigate and make a decision, that dispute is closed. However, you can file a complaint with the CFPB or your state's banking regulator, and you can provide new evidence to your bank if you discover something you did not have during the first investigation. If the bank agrees the new evidence changes the outcome, they may reopen the dispute.
