What Is a Credit Card Chargeback and How Does It Work?

A credit card chargeback is a reversal of a charge on your credit card that your card issuer performs after you dispute the transaction. Federal law, primarily the Fair Credit Billing Act, gives you the right to challenge billing errors within set deadlines, caps your liability for unauthorized charges at $50, and prevents your issuer from collecting the disputed amount or reporting it as delinquent while the investigation is open.¹²

When You Can File a Chargeback

The Fair Credit Billing Act defines a “billing error” broadly. Under 15 U.S.C. § 1666, you can dispute:¹

An unauthorized charge you did not make.
A charge for a different amount than you agreed to pay.
A charge for goods or services that were never delivered as agreed.
A missing refund or credit the merchant promised.
A calculation mistake on your statement.

Regulation Z tracks these same categories and spells out how issuers must handle each.³ Chargebacks are not limited to fraud. A duplicate charge, an unposted payment, or a subscription that keeps billing after you canceled all qualify.

Quality Complaints Come With Conditions

If you actually received the item but it was defective or significantly different from what was described, a separate provision applies. Under 15 U.S.C. § 1666i, you can raise the complaint against your card issuer only if:⁴

You first made a good-faith attempt to resolve the problem with the merchant.
The transaction was for more than $50.
The purchase happened in your home state or within 100 miles of your billing address.

The dollar and distance limits fall away if the merchant is affiliated with your card issuer, or if you bought through a mail or internet solicitation the issuer participated in.⁴ They also do not apply to the billing-error categories above; an unauthorized charge or a non-delivery can be disputed regardless of price or where the purchase occurred.

How Much You Can Be Held Liable For

Under 15 U.S.C. § 1643, the most you can owe for unauthorized charges is $50, and even that requires the issuer to have met notice conditions.² Report the card lost or stolen before it is used and you owe nothing. If a thief uses only your account number without possession of the physical card, you also owe nothing.⁵

The card networks go further. Visa’s Zero Liability Policy guarantees that cardholders will not be held responsible for unauthorized charges on their accounts, and Mastercard has a similar policy.⁶ For most consumer credit cards, that puts your practical exposure at $0, though certain commercial cards and anonymous prepaid cards may fall outside the network guarantee.

Note that debit cards work differently. Reporting an unauthorized debit charge more than two business days after learning about it raises your liability to $500, and waiting past 60 days after your statement was sent can cost you everything taken from the account.⁵ Credit cards carry no such escalating liability.

How to File

Gather the transaction date, exact amount, and merchant name as it appears on your statement. Write a plain description of what went wrong — “item never delivered,” “charged twice for one order,” “canceled subscription still billing.” If the complaint is about quality, note when and how you contacted the merchant and what they said.

Supporting documents help. Useful evidence includes order confirmations, shipping tracking, return receipts, screenshots of the product page or listing, and any emails or chat logs with customer service. For unauthorized charges, a police report or identity theft affidavit can strengthen the file.

Most issuers let you file through their app or online banking; look for a “dispute this charge” link next to the transaction. You can also call the number on the back of the card or write to the billing inquiries address (not the payment address) shown on your statement.⁷

The Deadlines That Control the Process

Three federal deadlines matter:

You have 60 days from the date the first statement showing the error was sent to notify your issuer. Miss it and you can forfeit your federal dispute rights for that charge.¹
The issuer has 30 days to send you written acknowledgment, unless it resolves the dispute inside that window.⁸
The issuer must complete the investigation within two billing cycles, and never more than 90 days after receiving your notice.⁸

Card networks add their own deadlines for merchants. Visa gives a merchant 30 days to answer with rebuttal evidence, and a merchant who misses that window typically loses the dispute by default.

Your Protections While the Bank Investigates

From the moment you file until the case is resolved, Regulation Z prevents the issuer from doing several things:³

It cannot try to collect the disputed amount or related finance charges. You still owe the undisputed portion of your bill.
It cannot report the disputed amount as delinquent to any credit bureau, or threaten to.⁹
It cannot accelerate your debt, restrict the account, or close it because you filed the dispute in good faith.

If you have automatic payments running against the card, the issuer must stop pulling the disputed amount from your bank account as long as you file at least three business days before the next scheduled payment. Some issuers post a provisional credit while they investigate, but that is a business choice, not a legal requirement.³

How the Investigation Ends

Your issuer reviews the claim against the legal definition of a billing error. If it looks valid on its face, the issuer routes the dispute to the merchant’s bank, which passes it to the merchant. The merchant has a window — typically 30 days under network rules — to answer with evidence such as a signed delivery receipt, proof of a refund already issued, or the terms you agreed to at checkout.

If the merchant fails to respond or cannot prove the charge was correct, the issuer resolves in your favor. Any provisional credit becomes permanent, or the charge is removed. If the issuer sides with the merchant, any temporary credit is reversed, the original charge is restored, and the issuer must send you a written explanation.⁸

After a denial, you get at least 10 days (or the number of days your credit agreement gives for paying undisputed amounts, whichever is greater) before the amount can be reported delinquent. If you send written notice that you still disagree, the issuer can only report the amount as delinquent if it also reports that the amount is in dispute and tells you which bureaus received the report.⁹

If You Disagree With the Outcome

A denial is not always final. The card networks run multi-stage dispute systems, and under Mastercard’s process a denied case can be re-presented, escalated to a pre-arbitration case, and taken to formal arbitration; the losing party has 45 calendar days to appeal.¹⁰ Your issuing bank handles these escalations for you, so call and ask what further steps are available.

If you believe the issuer itself mishandled the dispute or violated the Fair Credit Billing Act, file a complaint with the Consumer Financial Protection Bureau. The CFPB forwards complaints to the company, which usually answers within 15 days. Complaints can be filed online or by phone at (855) 411-2372.¹¹

When Not to File

Chargebacks exist for genuine problems, and misusing them has consequences. Disputing a charge for something you actually received and were happy with — often called “friendly fraud” — can get you blocked by the merchant, and businesses do keep internal lists of customers with repeat disputes.

A knowingly false chargeback can also cross into fraud. If a merchant or bank concludes you received the goods and invented a dispute, you can face account closure, reversal of the credit, and in serious cases criminal exposure under state theft or fraud laws. Issuers who see a pattern of abuse may decline to process further disputes from your account.

Try the merchant first, keep proof of the attempt, and file the chargeback when the merchant will not fix the problem. That is the situation the law was written for, and it is the ground your dispute stands on strongest.
