A chargeback is a reversal of a credit or debit card transaction that you request through your bank rather than the merchant. Federal law gives you the right to one when a charge is unauthorized, posted for the wrong amount, or made for goods or services you never received or that arrived in a condition significantly different from what was promised. The bank pulls the money back from the merchant’s account while it investigates, and the rules, deadlines, and your financial exposure all depend on whether the card involved was credit or debit.
Chargeback or Refund: Which One You Actually Want
A refund comes from the merchant. You ask, they agree, the money comes back in a few days, and nothing goes on any formal record. A chargeback goes around the merchant entirely and uses your bank as the lever.
Most banks expect you to try the merchant first. If you file a chargeback and the merchant can show they offered a refund you ignored, your dispute is more likely to fail. Chargebacks also cost merchants well beyond the sale amount in processing fees, and repeat disputes can land them in a card network penalty program. Save the chargeback for situations where the merchant won’t cooperate, has disappeared, or where someone used your card without permission.
When You Can File a Chargeback
Two federal statutes set the ground rules. For credit cards, the Fair Credit Billing Act covers billing errors: charges you didn’t authorize, charges for the wrong amount, charges for goods or services you never received, charges for items delivered in a condition significantly different from what was promised, and computational errors on your statement.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors2Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution
For debit cards, the Electronic Fund Transfer Act provides parallel protections, covering unauthorized transfers, incorrect amounts posted to your account, and transactions on your statement that you didn’t make.3Office of the Law Revision Counsel. 15 USC 1693f – Error Resolution “I changed my mind” and “I don’t like it” are not on either list. Buyer’s remorse is a refund conversation with the merchant, not a chargeback.
The Deadlines That Trip People Up
The clocks run shorter than most cardholders realize, and missing one can cost you the whole dispute.
For credit cards under the FCBA, you have 60 days from the date your creditor sends the statement containing the error to submit a written billing error notice.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
For debit cards under Regulation E, you must report unauthorized transactions appearing on a periodic statement within 60 days of when the institution sent that statement. Miss that window and you face unlimited liability for any unauthorized transfers that happen after the 60 days close.4Consumer Financial Protection Bureau. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
Card networks run their own timers alongside the federal ones. Visa generally allows up to 120 days from the transaction or expected delivery date to file a dispute, with select reason codes stretching to 540 days. Mastercard and the others maintain similar windows. You have to meet both the federal and the network deadline, and in practice the 60-day federal clock is the one that catches people out when they don’t review their statements each month.
Credit vs. Debit: Why Your Exposure Isn’t the Same
This is the part worth knowing before anything goes wrong.
If someone makes unauthorized purchases on your credit card, federal law caps your liability at $50, and most major issuers waive even that.5Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card The money at risk during the dispute is the bank’s, not yours.
Debit is different. The funds come straight out of your checking account, and your liability depends on how fast you report:
- Report within 2 business days of learning your card was lost or stolen, and your liability caps at $50.
- Report after 2 business days but within 60 days of the statement being sent, and liability rises to $500.
- Report after 60 days, and you face unlimited liability for unauthorized transfers that happen after the 60-day window and before you notify the bank.4Consumer Financial Protection Bureau. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
Unlimited means what it sounds like. If a thief drains your account over several months and you never checked your statements, the bank has no obligation to make you whole for anything that moved after the 60-day mark. This is the single strongest argument for reviewing your bank statements every month, and for using credit over debit when you can.
How to File One
Most banks let you start a dispute through their mobile app or online portal, usually under something labeled “dispute transaction” or “report a problem.” You’ll need the transaction date, dollar amount, and merchant name from your statement. Gather supporting evidence before you start: receipts, tracking numbers, screenshots of what was advertised versus what arrived, and any record of your attempt to resolve things with the merchant.
For credit card disputes, there’s a reason to also send a written notice by certified mail to the billing inquiry address printed on your statement. The FCBA’s procedural protections are triggered by written notice sent to that specific address.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors Many creditors now treat electronic submissions as satisfying the requirement, but certified mail gives you a delivery receipt that nails down exactly when the notice arrived.2Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution
Once the bank accepts your dispute, you’ll get a claim number. Keep it, and reference it on every follow-up.
What the Bank Does Next
What happens after you file depends on the card.
Credit Cards
After your creditor receives your written notice, it must resolve the dispute within two complete billing cycles, and no longer than 90 days.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors While the investigation is open, the creditor cannot try to collect the disputed amount or report it as delinquent, and you don’t have to pay the disputed portion of your bill.2Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution The creditor may issue a temporary credit, but it isn’t required to.
Debit Cards
The timeline is tighter, and provisional credit is more concrete. Your bank must investigate and reach a determination within 10 business days of receiving your error notice. It can extend the investigation to 45 days, but only if it provisionally credits your account within those first 10 business days.6Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors The provisional credit must include interest where applicable, and you get full use of the funds during the review.3Office of the Law Revision Counsel. 15 USC 1693f – Error Resolution
For new accounts (within 30 days of the first deposit) or certain transaction types like point-of-sale debit card purchases, the bank gets 20 business days before it must issue provisional credit, and up to 90 days total to finish investigating.6Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors
What the Merchant Can Do
The merchant receives notice of the dispute and gets a window to respond. They may submit signed delivery receipts, IP logs showing you accessed a digital product, customer service records, or proof the item matched its description. If that evidence is strong, your bank can reverse the provisional credit and deny your claim. If the merchant doesn’t respond or the evidence is thin, the chargeback stands. If your bank closes your case and you believe the decision was wrong, ask your issuer whether the dispute can be escalated to the card network for arbitration.
The Risk of Filing One You Shouldn’t
The chargeback system runs on good faith, and misusing it carries real consequences. Filing a chargeback for a legitimate purchase you actually received, sometimes called friendly fraud, is one of the most common abuses, and merchants have gotten better at fighting back.
If the merchant successfully challenges your dispute with evidence that you got what you paid for, you lose the provisional credit and owe the full amount. The merchant can block you from future purchases. Your bank notices too: a pattern of chargebacks that get reversed signals that you may be using disputes dishonestly, which can lead to account reviews or closure.
In extreme cases, chargeback fraud draws legal action. Merchants have won civil suits to recover high-value chargebacks, and repeat offenders who use disputes as a pattern of theft have faced fraud charges. One questionable dispute probably won’t put you in court, but the system has more teeth than people assume.
