How Credit Card Chargebacks Work: Billing Errors, Deadlines, and Disputes

A credit card chargeback is how federal law lets you reverse a charge by going to your card issuer instead of the merchant: you send written notice of a billing error within 60 days of the statement, the issuer investigates, and it must resolve the dispute within two billing cycles and no more than 90 days. Understanding how credit card chargebacks work means knowing which problems qualify, how to file so the protections actually attach, and what the issuer can and cannot do while your money is in limbo.

What Counts as a Billing Error

The Fair Credit Billing Act governs disputes on credit card accounts and defines the specific problems you can formally challenge.¹ Those categories are:

Unauthorized charges made by someone who had no permission to use your card. Your maximum liability is $50 before you notify the issuer, and nothing for further unauthorized use after notification. Most major issuers go further with zero-liability policies.²
Wrong amounts, including a single purchase posted more than once or a price different from what you agreed to pay.
Goods or services that were never delivered, or that arrived materially different from what was described.
Missing credits, where a payment you made or a refund you were promised never posted.
Charges you don’t recognize and need explained with supporting documentation.

A separate provision in the same law lets you raise any claim or defense you have against the merchant directly against the card issuer, but that right carries additional limits covered below.³

The 60-Day Deadline and How to Send Notice

The clock that matters is 60 days from the date your issuer sent the statement containing the disputed charge. Written notice must reach the issuer within that window or you lose the federal protections that force an investigation.¹ Card networks like Visa separately allow chargebacks up to 120 days from the transaction date, but the FCBA’s 60-day rule from the statement date is the enforceable federal standard, so treat it as your deadline.

The notice has to be in writing and sent to the billing-inquiry address the issuer discloses, not the payment address.¹ A note on your payment stub does not count unless the issuer specifically allows it. Include your name and account number, identify the charge, state the amount, and explain why it’s wrong. Most issuers accept disputes through their app or website, which is faster; a certified letter to the designated address gives you a documented paper trail that unambiguously satisfies the statute.

What to Have Ready Before You File

Identify the charge the way the statement shows it. The merchant’s billing name often differs from the storefront name you remember, so pull the exact descriptor, the transaction date, and the amount. If your online banking shows a transaction identification number, include that too.

Then gather whatever supports your version of events:

Receipts, order confirmations, and invoices showing the price you agreed to pay.
Shipping records, tracking numbers, and delivery confirmations, or screenshots showing a package never arrived.
Contracts or service terms if the dispute involves a service rather than a product.
Timestamped emails, chat transcripts, or call notes showing you tried to resolve the problem with the merchant first.
Photographs comparing damaged or materially different merchandise to the original listing.

For software, downloads, and subscriptions, save screenshots of account activity and any logs showing whether you received or used the product. Compile everything digitally; most issuer portals accept uploads.

What Happens After You File

Once a valid billing-error notice arrives, your issuer has 30 days to acknowledge it in writing, unless the entire dispute is resolved within that same 30 days.⁴ Most issuers post a provisional credit to your account so you aren’t carrying the disputed balance during the investigation.

The issuer sends the dispute through to the merchant with a reason code identifying the type of challenge. The merchant typically has 20 to 45 days to respond with rebuttal evidence, depending on the card network’s rules.⁵ No response, or a weak one, and the provisional credit becomes permanent.

Your issuer must complete the investigation within two complete billing cycles, and in no case more than 90 days, from the date it received your notice.¹ If the issuer sides with the merchant, the provisional credit is reversed and you owe the original charge plus any finance charges that accrued. If it sides with you, the reversal is permanent. A contested dispute that drags into appeals can stretch the overall timeline to about 120 days.⁵

What the Issuer Cannot Do While Your Dispute Is Open

During the investigation, your issuer cannot report the disputed amount as delinquent to any credit bureau, and it cannot threaten your credit over the unpaid portion.⁶ It also cannot take collection action on the disputed portion before the investigation is finished.¹

If the issuer concludes the charge was correct, it has to give you at least 10 days to pay before treating the amount as overdue. If you still disagree, you can send a second written notice. At that point the issuer may report the amount as delinquent, but only if it reports simultaneously that the amount is disputed and tells you the name and address of every party it notified.⁶ An issuer that breaks these rules forfeits the right to collect the disputed amount and related finance charges, up to $50.¹

Disputes About Quality of Goods or Service

When the problem is quality or a merchant’s refusal to honor a return rather than a straightforward billing error, you can still assert claims against your card issuer, with two added restrictions. The purchase must have exceeded $50 and must have taken place in your home state or within 100 miles of your billing address.³ You also have to make a good-faith attempt to work it out with the merchant first.

Those limits drop away in several situations: the card issuer is the seller, controls the seller, shares common ownership with the seller, is a franchised dealer of the issuer’s products, or participated in a mail or online solicitation that led to your order.³ Many online purchases involve marketing relationships that fit those exceptions, so the 100-mile rule blocks fewer e-commerce disputes than it looks like at first. The statute hasn’t been updated to speak directly to internet transactions, though, so always contact the merchant before escalating.

Debit Card Purchases Are a Different Regime

If you paid with a debit card, the FCBA does not apply. A separate law, the Electronic Fund Transfer Act implemented through Regulation E, governs, and the protections are narrower.

Liability for unauthorized debit card transactions depends on how fast you report:⁷

Within 2 business days of learning of the loss, your liability is capped at $50.
After 2 business days but within 60 days of the statement, liability can reach $500.
After 60 days from the statement, you can be liable for the full amount of unauthorized transfers that happen after the 60-day window.

Regulation E also defines “errors” more narrowly. It covers unauthorized transfers and incorrect amounts, but not disputes about the quality of goods or services. A defective product paid for by debit card is not something your bank is federally required to reverse. The credit card route gives you both the billing-error categories and the broader claims-and-defenses provision, which is why using a credit card matters most when delivery or quality risk is real.

When Filing a Chargeback Is the Wrong Move

Disputing a charge for something you actually ordered and received, sometimes called friendly fraud, has consequences. Issuers track dispute patterns, and repeated invalid chargebacks can get your account flagged, your limits reduced, or your account closed. Serious cases can be reported to credit bureaus.

Merchants can also push back hard. Delivery confirmations, IP address logs, and download records are the kind of evidence that defeats a disputed charge, and if the issuer sides with the merchant you owe the original amount plus any finance charges that accrued while the dispute was open.

A chargeback is not a replacement for a refund request. For buyer’s remorse, a canceled subscription, or a forgotten authorization, start with the merchant. The dispute process is for charges you didn’t make, charges that are wrong, orders the merchant failed to deliver, and complaints the merchant refuses to address.
