What Is a Chargeback on a Bank Statement: Rules and Deadlines

A chargeback on a bank statement is a reversal that moves money from a merchant back into your account after you dispute a transaction with your bank. It shows up as a credit entry that offsets the original charge. Two federal laws sit behind these reversals: the Fair Credit Billing Act, which governs credit card disputes, and the Electronic Fund Transfer Act, which governs debit cards and other electronic payments. Your rights, your deadlines, and how much you could lose depend heavily on which one applies.

How It Appears on Your Statement

A chargeback posts as a credit, usually in a different color than regular purchases or with a positive dollar amount next to the original merchant’s name. Labels vary by bank. Common shorthand includes “CB,” “REV,” “Disputed Trans,” or “Adj.” The amount should match the original charge, though a partial reversal for only part of the disputed amount is also possible.

If you filed a dispute and don’t see any of these indicators within a few business days, check your pending transactions or call your bank to confirm it received the claim. The credit entry is the bank’s acknowledgment that your dispute is in motion.

Credit Cards and Debit Cards Follow Different Rules

This is the distinction most people miss until it costs them. Credit cards and debit cards operate under different federal regulations, and credit cards offer stronger protections.

Credit Cards: The Fair Credit Billing Act

Credit card disputes fall under 15 U.S.C. § 1666. Valid billing errors include unauthorized charges, charges for the wrong amount, charges for goods that were never delivered, and computational mistakes on your statement. You have 60 days from the date your statement is sent to submit a written dispute to your card issuer.¹ The issuer must acknowledge the dispute within 30 days and resolve it within two complete billing cycles, which can’t exceed 90 days.²

During the investigation, the creditor cannot try to collect the disputed amount, charge interest on it, or report it as delinquent to credit bureaus. You still have to pay any undisputed portion of the bill, but the challenged amount is essentially frozen until the bank reaches a decision.²

Credit cards also give you a separate right to push back on purchases that went wrong. Under 15 U.S.C. § 1666i, you can assert claims against your card issuer for problems with a merchant, like damaged goods or services that were never provided. There’s a catch: the original purchase must exceed $50, and it must have occurred in your home state or within 100 miles of your billing address. Those limits don’t apply if the merchant is affiliated with your card issuer or if you were solicited by mail.³ The law also requires a good-faith attempt to resolve the issue with the merchant before you assert these claims against the card issuer.

Debit Cards: Regulation E

Debit card disputes follow Regulation E (12 CFR Part 1005), which defines “errors” more narrowly. Covered errors include unauthorized transfers, incorrect transfer amounts, transfers missing from your statement, and bookkeeping mistakes by your bank.⁴ Regulation E does not cover merchandise disputes. If you used a debit card to buy something that arrived damaged or wasn’t as described, federal error resolution rules don’t require your bank to reverse the charge. Your bank’s voluntary policies or the card network’s rules may still help, but federal law doesn’t require it the way it does for credit cards.

For an unauthorized debit card transaction, you have 60 days from the date your bank sends the statement to report the error.⁵

Deadlines and What You Lose if You Miss Them

How much you could lose depends on the card type and how fast you report.

Credit Card Liability

Federal law caps your liability for unauthorized credit card use at $50, no matter how much the thief charges. That cap applies if the issuer gave you a way to report the loss and identified you as the authorized user. Most major card networks offer zero-liability policies that go further than the law requires, so in practice you usually owe nothing at all for fraudulent credit card charges.⁶

Debit Card Liability

Debit cards are a different story, and speed is everything. The tiers:

Reported within 2 business days: Your loss is capped at $50, or the amount of unauthorized transfers before you notified the bank, whichever is less.
Reported after 2 business days but within 60 days of the statement: Your loss can reach up to $500, including up to $50 for transfers in the first two days plus whatever the thief charged between day three and your notification.
Reported after 60 days from the statement date: You face unlimited liability for unauthorized transfers that occur after that window closes. The bank only has to cover transfers it can prove it would have stopped if you had reported sooner.

If someone drains your checking account with a stolen debit card and you don’t notice for three months, you may not recover anything that happened after the 60-day mark.⁵

What Qualifies as a Valid Chargeback

Not every purchase you regret qualifies. Federal law and card network rules limit chargebacks to specific situations. The strongest grounds:

Unauthorized charges. Someone used your card without permission, through identity theft, a stolen number, or a skimmed card.
Billing errors. You were charged the wrong amount, billed twice for one purchase, or a charge appeared that doesn’t match any transaction you made.
Non-delivery. You paid for goods or services that never arrived. For credit cards, the law specifically bars the issuer from treating the charge as valid unless the merchant can prove the items were actually sent.¹
Goods not as described. What you received was materially different from what was advertised. This ground is stronger for credit cards than for debit cards.
Canceled recurring charges. A merchant keeps billing after you’ve canceled a subscription or service.

Buyer’s remorse doesn’t qualify. Neither does a dispute over the quality of a service the merchant actually performed as agreed.

How to File the Dispute

Try the merchant first. A direct refund is faster and simpler than a chargeback, and for credit card claims against the issuer involving merchant problems, a good-faith attempt at resolution is actually a legal prerequisite.³ If the merchant won’t help, move to a formal dispute.

Gather the transaction date, exact dollar amount, and merchant name as shown on your statement, plus any transaction ID or reference number. For non-delivery claims, keep shipping tracking numbers. For goods-not-as-described disputes, keep photos of what arrived next to the listing. Save emails, chat logs, or call records showing you tried the merchant first.

Most banks let you open a dispute through their app or online banking. For credit card billing errors, though, the Fair Credit Billing Act requires written notice to reach the creditor at the address designated for billing inquiries within 60 days of the statement date. Writing on a payment stub doesn’t count if the creditor’s disclosures say so.¹ Your notice should include your name, account number, the amount in question, and why you believe it’s wrong. Even if you start online, a written follow-up by certified mail gives you proof you met the deadline.

For debit card disputes, Regulation E allows oral or written notice. The bank must investigate an oral report the same way it investigates a written one, though it can ask you to follow up in writing within 10 business days.⁴

Investigation Timelines and Provisional Credits

How long the investigation runs depends again on the card type.

For credit cards, your issuer must acknowledge the dispute within 30 days of receiving it. The investigation has to wrap up within two full billing cycles, and no longer than 90 days.² During that time, you don’t have to pay the disputed amount and the issuer can’t report you as delinquent for not paying it.

For debit cards, your bank has 10 business days to investigate and reach a conclusion. It can extend the investigation to 45 days, but only if it provisionally credits your account within the first 10 business days. The bank may hold back up to $50 of the provisional credit if it reasonably believes the unauthorized transfer occurred, and must inform you within two business days of issuing the provisional credit, including the amount and date.⁴

Certain transactions get longer timelines. New accounts (within 30 days of your first deposit) get 20 business days instead of 10, and 90 days instead of 45. Foreign transactions and certain point-of-sale transfers also qualify for the 90-day window.⁴

If the bank finds the error occurred, it must correct it within one business day. If it denies the claim, the provisional credit gets revoked and the bank must explain its reasoning in writing within three business days of finishing the investigation.

If Your Dispute Is Denied

A denial isn’t necessarily the end. For credit card disputes, the issuer must send a written explanation of why it believes the charge was correct, and you can request copies of the documents it relied on.¹ Read them carefully. If a signed receipt doesn’t match your signature, or a delivery confirmation shows an address that isn’t yours, that’s new evidence worth raising.

You can submit a written rebuttal with additional evidence. Some banks have a formal appeals process; others reopen the investigation when new information surfaces. If the bank still won’t budge, you can file a complaint with the Consumer Financial Protection Bureau. The CFPB forwards complaints to the bank, which typically responds within 15 days.⁷ For smaller amounts, small claims court is also an option, with filing limits set by each state.

Don’t File One You Don’t Deserve

Filing a chargeback for a purchase you made and received, sometimes called “friendly fraud,” carries real risk. Banks track dispute patterns, and consumers who file excessive or unfounded claims can have their accounts flagged, restricted, or closed. Card networks maintain databases of consumers with suspicious chargeback histories, which can follow you to other financial institutions.

The legal exposure is more serious than most people realize. A knowingly false chargeback can constitute bank fraud under federal law, which carries penalties of up to $1,000,000 in fines, up to 30 years in prison, or both.⁸ Merchants can also pursue civil claims to recover their losses. Criminal prosecution for a single false chargeback on a small purchase is rare in practice, but organized or repeated abuse draws law enforcement attention.
