A chargeback in banking is a bank-initiated reversal of a card transaction that returns money to your account when a charge is unauthorized, incorrect, or for goods or services you did not receive as promised. Federal law caps your liability for unauthorized credit card charges at $50, while debit card protections depend on how quickly you report the problem. The rules that govern the process — deadlines, evidence, and what your bank must do — are set by statute, and they differ depending on which card you used.
Chargeback vs. Refund
A refund is voluntary. The merchant agrees to return your money and sends it back. A chargeback is not voluntary. Your bank forcibly reverses the transaction and pulls the funds from the merchant’s account, even if the merchant disagrees. You typically start the process when you spot a charge on your statement that you believe is unauthorized, wrong, or tied to something you never received.
Your Rights on a Credit Card Charge
The Fair Credit Billing Act sets the rules when you dispute a credit card charge. Your maximum liability for unauthorized use is $50, and even that cap only applies where specific conditions are met: the card was an accepted card, the issuer gave you notice of your potential liability, and the unauthorized use happened before you reported the card lost or stolen.1Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card Most major issuers go further and offer zero-liability policies in practice.
To get the law’s protections, you must send a written dispute to your card issuer within 60 days of receiving the first statement that shows the error. Your notice needs to identify your name and account number, describe the error and the amount, and explain why you believe the charge is wrong.2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors Once the issuer receives your notice, it must acknowledge the dispute in writing within 30 days and resolve the investigation within two complete billing cycles, and in any event within 90 days.3eCFR. 12 CFR 1026.13 – Billing Error Resolution
While the investigation is open, you don’t have to pay the disputed amount or any interest accruing on it, and the issuer cannot try to collect. If the issuer concludes the charge was correct, it has to send you a written explanation and, on request, provide copies of the evidence it relied on.2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Your Rights on a Debit Card Charge
Debit card disputes fall under the Electronic Fund Transfer Act and Regulation E. The protections aren’t as generous as credit card rules, and how much you could lose depends entirely on how fast you act.
- Reported within 2 business days: your liability is capped at $50, or the actual amount of the unauthorized transfers if that’s less.4eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Reported after 2 business days but within 60 days of your statement: your liability can rise to $500, covering unauthorized transfers that happened after the two-day window and before you told the bank.4eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Not reported within 60 days of your statement: you could face unlimited liability for unauthorized transfers that occur after that 60-day window, as long as the bank can show those transfers wouldn’t have happened if you had reported sooner.5GovInfo. 15 USC 1693g – Consumer Liability
Your bank normally has 10 business days to investigate. If it needs longer, it can take up to 45 calendar days, but only if it puts a provisional credit for the disputed amount into your account within those first 10 business days so you have access to the funds while the case continues.6Consumer Financial Protection Bureau. 12 CFR Part 1005.11 – Procedures for Resolving Errors The bank must also tell you the amount and date of the provisional credit within two business days of issuing it.
What Counts as a Billing Error
Federal law spells out which categories of credit card problems qualify for the dispute process. Knowing which one fits helps you pick the right reason when you file.
- Unauthorized charges you did not make or authorize.
- Charges posted for a different amount than what you actually agreed to pay.
- Goods or services that were never delivered or never accepted.
- Payments or credits your issuer failed to apply to your account.
- Computational or accounting mistakes by the creditor on your statement.
- Charges you need more information about, including documentary proof of the transaction.
- Missing statements, if your creditor failed to send one to the address you gave at least 20 days before the end of the billing cycle.2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Visa and Mastercard also maintain their own reason code systems covering additional scenarios like duplicate processing or charges after cancellation. Your bank’s dispute form usually walks you to the right code.
How to File a Chargeback
Contact the merchant first. Many banks want to see evidence that you made a good-faith effort to sort out the problem privately before they process a chargeback. Keep the receipts of that effort: email threads with timestamps, chat transcripts, phone call dates and durations, and any written responses.
When you’re ready to file, pull together:
- Transaction details — the exact posting date, the merchant name as it appears on your statement, and the precise dollar amount.
- Supporting evidence — photos of defective items, cancellation confirmations, shipping tracking, or copies of the merchant’s return policy.
- Communication records — proof of your attempts to resolve the issue, with dates, method, and the merchant’s response or silence.
- For digital goods, delivery confirmation emails, access credentials, or account activity records.
Most banks let you file through their online portal or mobile app by selecting the disputed transaction and following the prompts. You can also mail a signed letter to the billing inquiries address your statement discloses, or call a dedicated dispute line. If you file by phone, ask for written confirmation. For credit card disputes, the 60-day clock starts on the date the issuer transmitted the statement containing the error, so don’t delay.3eCFR. 12 CFR 1026.13 – Billing Error Resolution
What Happens After You File
Your bank assigns a case number and starts investigating. For a credit card, it must acknowledge within 30 days and resolve within two billing cycles, capped at 90 days. For a debit card, the initial window is 10 business days, extendable to 45 calendar days if the bank issues a provisional credit.6Consumer Financial Protection Bureau. 12 CFR Part 1005.11 – Procedures for Resolving Errors The bank contacts the merchant’s side and forwards your claim, and you’ll get the final decision by letter or app notification.
The merchant can fight back through a process called representment. Under Visa’s dispute rules, the merchant generally has 30 days to submit evidence defending the charge. If nothing comes in by the deadline, the dispute typically resolves in your favor by default. Mastercard follows a similar timeline, with disputes for defective or undelivered goods generally filed within 120 calendar days of the transaction or delivery date.7Mastercard. Chargeback Guide Merchant Edition If the merchant produces compelling evidence, such as delivery confirmation or a signed receipt, your bank may reverse the provisional credit and reinstate the charge, and it will tell you why.
Your Credit Score While a Dispute Is Open
While a credit card dispute is under investigation, your issuer cannot report the disputed amount as delinquent to the credit bureaus. It also cannot threaten your credit standing because you declined to pay the disputed charge.8Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports
If the investigation ends against you and you still believe the charge is wrong, you can send a follow-up written notice within the payment period the issuer allows. At that point the issuer can report the amount, but only if it also reports the amount is in dispute and tells you which parties it has notified.8Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports This protection is a credit card protection. Debit card disputes don’t touch your credit report because debit transactions aren’t extensions of credit.
Defective or Misrepresented Purchases: The Claims and Defenses Rule
Beyond straightforward billing errors, the Fair Credit Billing Act gives you an extra right when you buy something defective or misrepresented on a credit card. Under the claims and defenses rule, you can assert against your card issuer the same legal claims you’d have against the merchant, such as a defective product or a service that was never performed as promised.9Office of the Law Revision Counsel. 15 USC 1666i – Assertion by Cardholder Against Card Issuer of Claims and Defenses Arising Out of Credit Card Transaction
This right has conditions. You must first have made a good-faith attempt to resolve the problem with the merchant. The transaction must exceed $50, and the purchase must have occurred in your home state or within 100 miles of your mailing address.9Office of the Law Revision Counsel. 15 USC 1666i – Assertion by Cardholder Against Card Issuer of Claims and Defenses Arising Out of Credit Card Transaction The geographic and dollar limits fall away if the merchant is the same company as the card issuer, is controlled by the issuer, or solicited the transaction through a mailing the issuer participated in.
Don’t File a False Chargeback
Filing a chargeback for a purchase you actually made and received, sometimes called friendly fraud, carries real consequences. Your bank can reverse the credit, close your account, and flag you internally as a dispute abuser, which makes it harder to open accounts or file legitimate disputes later.
Intentionally filing a false chargeback can also be federal fraud. Knowingly using an access device, which includes credit and debit cards, to obtain something of value through fraud can result in a fine and up to 10 or 15 years in prison depending on the conduct.10Office of the Law Revision Counsel. 18 USC 1029 – Fraud and Related Activity in Connection With Access Devices Merchants can also sue. Only file when you genuinely believe the charge is unauthorized, incorrect, or for something you didn’t receive as agreed.
If Your Chargeback Is Denied
If the bank sides with the merchant, read the written explanation the bank has to provide. It should lay out the evidence the merchant submitted and the reason for the denial. If you have new evidence that wasn’t in the original filing, ask your bank to reopen the case.
You can also file a complaint with the Consumer Financial Protection Bureau if you believe your bank failed to follow the required procedures. For a credit card, failing to acknowledge within 30 days or resolve within 90 days is itself a violation of federal law.3eCFR. 12 CFR 1026.13 – Billing Error Resolution
As a last resort, you can sue the merchant in small claims court. Filing fees vary by jurisdiction but generally run from about $15 to $305 depending on where you live and the amount claimed. You don’t need an attorney, and it can be an effective route for disputes worth a few hundred to a few thousand dollars.
