A chargeback works by reversing a payment you already made: your bank pulls the funds from the merchant’s account through the card network and returns them to you after an investigation. Two federal laws create this right — the Fair Credit Billing Act for credit cards and the Electronic Fund Transfer Act for debit cards — and each sets its own deadlines, liability caps, and investigation rules. The process involves you, your bank (the issuer), the merchant’s bank (the acquirer), and the card network, and it moves on a structured timeline you have to meet.
Try the Merchant Before You File
A direct refund is almost always faster than a formal dispute, so start with a call or email to the merchant and keep notes of every conversation: date, name, and what you were told.
For some credit card disputes, contacting the merchant first is more than good practice. When you are disputing the quality of goods or services rather than an unauthorized charge or a billing error, federal law requires a good-faith attempt to resolve the problem with the merchant before your issuer has to step in. The same rule limits quality disputes to transactions over $50 that took place in your home state or within 100 miles of your billing address, though those geographic and dollar limits do not apply to online or mail-order purchases where the card issuer participated in the solicitation.1Office of the Law Revision Counsel. 15 USC 1666i – Assertion by Cardholder Against Card Issuer
What Qualifies as a Valid Dispute
The Fair Credit Billing Act defines specific “billing errors” that let you dispute a credit card charge:
- Unauthorized charges made without your permission.
- Goods or services you paid for but never received.
- A charge for the wrong amount.
- Merchandise that was defective or significantly different from what was described at the time of sale.
- A refund the merchant agreed to but never processed.
The statute covers charges for goods or services “not accepted by the obligor” or “not delivered to the obligor in accordance with the agreement made at the time of a transaction.”2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Recurring subscription charges that continue after cancellation are a common trigger. Each billing cycle after your cancellation request can be disputed separately, and every major card network has a reason code for canceled recurring transactions. Save your cancellation confirmation and the date you requested it.
How to File the Dispute
For a credit card, the Fair Credit Billing Act requires written notice sent to your issuer’s billing inquiry address, not the general customer service address or the payment stub address. The notice must include your name, account number, the dollar amount you believe is wrong, and why you think the statement is in error. A phone call alone does not trigger the full statutory protections, so follow any call with a written letter or your issuer’s formal online dispute form.2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
For a debit card, the rules are more flexible. Your bank must accept notice of an error either orally or in writing, though it can ask you to confirm an oral report in writing within 10 business days.3eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors
Whatever card you used, gather your documentation before you file. That means the exact transaction date, the merchant name as it appears on your statement, the amount, order confirmations or receipts, emails and chat logs showing you tried to resolve the issue, delivery tracking, and photos of any damaged or incorrect items.
The Deadlines That Decide Your Case
For a credit card, you have 60 days from the date your issuer sent the first statement containing the error to put your dispute in writing. After that window closes, you lose the statutory protections that block collection and credit reporting while the dispute is pending.2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
For a debit card, you also have 60 days from the date the statement was sent to report an unauthorized transfer. Reporting later does not bar you from filing, but it exposes you to liability for unauthorized transfers that happen after the 60-day mark and before you notify the bank.4eCFR. 12 CFR 205.6 – Liability of Consumer for Unauthorized Transfers
What the Bank Does Next
Once your dispute reaches the issuer, timelines diverge based on the card type.
Credit Card Investigation
Your issuer must acknowledge the written dispute within 30 days of receiving it. It then has two full billing cycles, but no more than 90 days, to investigate and either correct the error or explain in writing why the charge was valid.2Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
During the investigation, you do not have to pay the disputed amount, and the issuer cannot charge interest or fees on it. The issuer also cannot report the disputed amount as delinquent to credit bureaus or threaten your credit standing while the matter is open.5Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports You do still have to pay the undisputed portion of the bill on time.
Debit Card Investigation
Your bank must investigate and resolve a debit card error within 10 business days of receiving your notice. If it needs more time, it can extend the investigation up to 45 days, but only if it provisionally credits your account within those first 10 business days for the amount in question. The bank is allowed to withhold up to $50 of the provisional credit when it reasonably believes an unauthorized transfer occurred.3eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors
When the Merchant Pushes Back
A chargeback is not final once you file it. After the card network forwards the dispute to the merchant’s bank, the merchant typically has 20 to 45 days to respond with evidence defending the original charge.6Mastercard. How Can Merchants Dispute Credit Card Chargebacks That response is called representment: the merchant is re-presenting the transaction and arguing it was legitimate.
The evidence a merchant submits varies with the dispute reason. For a claim that goods were defective or not as described, it might be a signed delivery receipt, proof of repair or replacement, or documentation that the item matched the listing. For a fraud claim, it might be address verification results or authentication data tying the purchase to you.
Your issuer then weighs the merchant’s evidence against yours and decides. If the issuer sides with the merchant, any provisional credit is reversed and the original charge returns to your account.
Pre-Arbitration and Arbitration
If the dispute is not resolved after the first round, either side can escalate to pre-arbitration, where each bank submits additional documentation. If the merchant’s bank accepts the pre-arbitration case or fails to respond within 30 calendar days, it takes financial responsibility for the amount.
If neither side gives in, the card network steps in as the final decision-maker through formal arbitration and issues a binding ruling. The losing party typically bears the cost, which is settled between the banks. You do not pay arbitration fees directly as the cardholder.
If You Lose the Dispute
When the issuer concludes the original charge was valid, you owe the disputed amount plus any finance charges that accumulated during the investigation. The issuer has to tell you the date payment is due and give you the same grace period you would have had before the dispute, so you have time to pay without additional interest.7Federal Trade Commission. Using Credit Cards and Disputing Charges
On the debit side, if the bank provisionally credited your account and then determines no error occurred, it can take the money back. It must notify you at least three business days before debiting the funds from your account.
Your Liability for Unauthorized Charges
Chargebacks also matter for stolen cards and fraud, and the protection you get depends heavily on which card was used.
Under the Fair Credit Billing Act, your maximum liability for unauthorized credit card charges is $50, and only when several conditions are met, including that the issuer gave you proper notice about potential liability and that the unauthorized use occurred before you reported the card lost or stolen. Report the card before any fraudulent charges post and you owe nothing. Most major issuers go further with zero-liability policies.8GovInfo. 15 USC 1643 – Liability of Holder of Credit Card
Debit card protection under the Electronic Fund Transfer Act is thinner and tied to how fast you report the problem:
- Report within 2 business days of learning about the loss or theft and your liability caps at $50.
- Report after 2 business days but within 60 days of your statement and the cap rises to $500.
- Report after 60 days and you can be responsible for the full amount of any unauthorized transfers that happen after the 60-day window, with no cap.
That uncapped tier is why speed matters more with a debit card than with a credit card.4eCFR. 12 CFR 205.6 – Liability of Consumer for Unauthorized Transfers
The Risk of Filing Chargebacks on Legitimate Charges
Disputing charges you actually authorized, sometimes called friendly fraud, carries real consequences. Banks track every dispute you file: the reason, the amount, and whether you won. Filing even two or three disputes in a short period can trigger a review of your account.
Possible outcomes include your bank closing your account without advance notice, your profile being flagged as high-risk and losing access to certain card features, and, in extreme cases, legal action by a merchant. Some jurisdictions treat intentional chargeback fraud as payment card fraud or wire fraud. Criminal prosecution is uncommon, but merchants do pursue civil suits against repeat offenders when losses are significant.
