Yes, you can dispute a checking account charge, and your bank has a legal process to handle it
When you spot a charge you don't recognize or didn't authorize, you can contact your bank and ask them to investigate. Your bank is required by federal law—specifically the Electronic Funds Transfer Act (EFTA)—to look into the dispute and either reverse the charge or explain why it was legitimate. The process takes time, usually 10 business days for an initial investigation and up to 45 days for a full resolution, but your bank must return your money while they investigate if the dispute meets certain conditions.
The key difference between a checking account dispute and a credit card dispute is that checking accounts are covered under the EFTA, not the Fair Credit Billing Act. This means the rules are slightly different: your bank has less time to investigate, but you also have less protection if you wait too long to report the problem. The sooner you report an unauthorized charge, the better your position.
Key Takeaways
- Report unauthorized charges to your bank as soon as you notice them; waiting more than 60 days can limit your protection to $500 of unauthorized transfers.
- Your bank must investigate within 10 business days and tell you the outcome, or provisionally credit your account while they continue looking.
- You will need to provide your bank with the transaction details—the date, amount, merchant name, and why you believe it is unauthorized.
- If your bank denies your dispute, they must send you a written explanation and tell you how to appeal their decision.
- Disputes for charges made in person with your debit card are harder to win than online or phone charges, because the merchant can claim you authorized it.
The difference between unauthorized charges and billing errors
An unauthorized charge is a transaction someone else made without your permission—a fraudster used your account number, or someone stole your debit card. A billing error is a mistake your bank or the merchant made: they charged you twice, charged you the wrong amount, or posted a charge to your account by accident.
Both can be disputed, but the bank treats them slightly differently. For unauthorized charges, the bank investigates whether the transaction actually happened and whether you authorized it. For billing errors, the bank checks their records and the merchant's records to see where the mistake occurred. The timeline and your protection are the same either way, but knowing which one you are reporting helps the bank route your case correctly.
How to report a charge to your bank
Contact your bank by phone, in writing, or through their online banking portal—whichever method they accept for disputes. Most banks have a dedicated fraud or disputes department; if you call the main customer service line, ask to be transferred. You do not need to visit a branch in person, though you can if you prefer.
When you report the charge, have the following information ready: the date of the transaction, the exact amount, the merchant name (as it appears on your statement), and a clear explanation of why you believe it is unauthorized or incorrect. If you know who made the charge or how they accessed your account, tell the bank that too. The bank will create a dispute case and assign it a reference number; write this down and keep it.
Some banks will ask you to submit a written dispute form or send a signed letter. If they do, follow their process exactly—banks are required to investigate only disputes that meet their procedural requirements. If you are unsure whether your report counts as an official dispute, ask the bank directly: "Have you opened a dispute case on this charge?"
What happens during the investigation
Once you report the charge, your bank has 10 business days to investigate and contact you with a result. During this time, they will check their records, contact the merchant if necessary, and determine whether the charge was authorized. If the investigation is not complete by day 10, the bank must provisionally credit your account—meaning they put the money back while they keep investigating. This provisional credit is not final; if they later determine the charge was legitimate, they can take the money back.
The full investigation can take up to 45 days. The bank will contact you when they reach a conclusion. If they find the charge was unauthorized, they will reverse it permanently and close the case. If they find the charge was authorized or legitimate, they will send you a written explanation of why, along with copies of the evidence they used to make that decision. They will also tell you how to appeal if you disagree.
When your bank might deny your dispute
Banks deny disputes most often when the evidence shows you authorized the charge, even if you do not remember doing so. This happens frequently with in-person debit card transactions: the merchant has a signed receipt or a PIN entry log showing someone used your card, and the bank assumes that person was you. It also happens with recurring charges you signed up for but forgot about—a subscription service, a gym membership, or an app you downloaded.
If you made the purchase yourself but the merchant charged you the wrong amount, or charged you twice, the bank will usually reverse the extra charge once they confirm the error with the merchant. But if you are claiming you never authorized the purchase at all, and the merchant has proof of authorization, the bank will likely deny the dispute.
Disputes are also harder to win if you waited a long time to report them. If you report an unauthorized charge more than 60 days after it posted, the EFTA limits your protection to $500 of unauthorized transfers. If you report it within 60 days, you have full protection. This is why checking your statements regularly matters.
What to do if your bank denies the dispute
When a bank denies a dispute, they must send you a written explanation within the timeframe required by law. This explanation should tell you specifically why they believe the charge was authorized or legitimate, and what evidence they reviewed. Read this carefully; sometimes banks make mistakes in their investigation.
If you disagree with the decision, you have the right to appeal. The bank must tell you how to appeal in their denial letter—usually by submitting additional evidence or a written response within a set number of days. If you have new information (a statement from a witness, proof that your card was lost on that date, a police report), include it with your appeal.
If the bank denies your appeal, you can file a complaint with your bank's regulator. Most banks are regulated by the Office of the Comptroller of the Currency (OCC), the Federal Reserve, or the Consumer Financial Protection Bureau (CFPB). You can file a complaint with the CFPB online at consumerfinance.gov. A complaint does not reverse the bank's decision, but it creates a record and may prompt the bank to reconsider.
How to protect your account from future charges
After a dispute is resolved, take steps to prevent the same thing from happening again. If your debit card was compromised, ask your bank to issue a new card with a new number. If someone had access to your account information, change your online banking password and enable two-factor authentication if your bank offers it.
For recurring charges you did not authorize, contact the merchant directly and ask them to stop billing you. Send this request in writing (email is fine) and keep a copy. If the merchant continues to charge you after you have asked them to stop, that is a separate violation, and you can report it to your bank as a new dispute or to the CFPB as a complaint.
Monitor your checking account regularly—weekly if possible. The sooner you spot an unauthorized charge, the sooner you can report it and the stronger your case will be.
Frequently Asked Questions
How long does it take to get my money back?
Your bank must tell you the outcome within 10 business days. If they cannot finish investigating by then, they must provisionally credit your account—put the money back—while they continue. The full investigation can take up to 45 days. Provisional credits usually stay in your account even if the bank later finds the charge was legitimate, though they can technically remove it.
What if the charge was made with my debit card in person?
In-person charges are harder to dispute because the merchant usually has a receipt or PIN entry showing someone used your card. If you did not make the purchase, you will need to prove your card was stolen or lost on that date, or that someone else had access to it. A police report helps. If you straightforward do not remember the purchase, the bank will likely deny the dispute.
Can I dispute a charge if I authorized it but changed my mind?
No. A dispute is for unauthorized charges or billing errors, not for purchases you regret. If you bought something and want to return it, contact the merchant directly. If the merchant refuses to refund you, that is a contract dispute, not a banking dispute.
What happens if I dispute a charge and then the merchant contacts me?
The merchant may contact you during the investigation to ask why you disputed the charge or to offer a refund. You can work it out with them directly if you want to. If you and the merchant reach an agreement, tell your bank and ask them to close the dispute. If the merchant refunds you, the dispute becomes unnecessary.
Do I have to pay the disputed charge while the investigation is happening?
No. If your bank provisionally credits your account, the money is yours to use while they investigate. You do not have to set it aside or hold it. However, if the bank later determines the charge was legitimate, they can remove the provisional credit from your account.
