Bank Chargeback: What It Is and How to File One

A bank chargeback is a reversal of a credit or debit card transaction that your bank processes after you dispute the charge, rather than something you negotiate with the merchant. Your right to one comes from federal law: the Fair Credit Billing Act for credit cards and the Electronic Fund Transfer Act for debit cards.¹ Those laws set out which charges you can challenge, how long you have to act, and what your bank must do once you file. The deadlines and liability rules differ sharply between credit and debit, and missing them can leave you stuck with the charge for good.

What You Can Dispute

Banks evaluate chargebacks against a defined list of billing errors, not against a general sense that something was unfair. Under Regulation Z, which implements the Fair Credit Billing Act, the qualifying categories for credit card disputes are:²

Unauthorized charges made without your permission.
Charges that post for the wrong amount or on the wrong date.
Goods or services you paid for and never received.
Goods or services that were materially different from what was advertised, such as a counterfeit item sold as authentic.
Duplicate charges for a single purchase.
Missing credits, including refunds the merchant promised but never issued.
Math errors on your statement.

Debit card disputes fall under Regulation E, which covers a parallel list: unauthorized electronic fund transfers, incorrect amounts, and computational errors on your statement.³

The Catch for Quality Complaints

If your complaint is about the quality of what you received rather than a flat billing error, federal law adds extra conditions before your card issuer has to involve itself. You must have first tried in good faith to resolve the problem with the merchant. The transaction must exceed $50, and the purchase must have occurred in your home state or within 100 miles of your billing address.⁴

Those distance and dollar limits drop away in certain cases. They don’t apply if the merchant is the same company as the card issuer, is controlled by the card issuer, or sold you the product through a mail solicitation the issuer took part in.⁴ Store-branded credit cards used at the issuing retailer therefore bypass the limits entirely. One further restriction: even when you qualify, you can only dispute up to the amount of credit still outstanding on that transaction at the time you notify the card issuer.

How Long You Have to File

Credit Cards: 60 Days

The Fair Credit Billing Act gives you 60 days from the date your creditor sends the statement containing the error.⁵ The clock starts when the statement goes out, not when you open it. Your notice must identify your account, state that you believe there’s an error, give the amount, and explain why you think the charge is wrong. Send it to the billing inquiries address, which is often different from the payment address.⁶

The statute calls for written notice. If your creditor’s billing rights disclosure says it accepts electronic submissions, an online or in-app dispute meets that requirement.⁶ Most major issuers now do. When in doubt, a certified letter is the safest route.

Debit Cards: Report Fast or Pay More

Debit card disputes work under the Electronic Fund Transfer Act, and your financial exposure for unauthorized transactions depends on how quickly you report:⁷

Within 2 business days of learning about the problem: liability capped at $50, or the amount of the unauthorized transfer if less.
After 2 business days but within 60 days of the statement: liability can rise to $500.
More than 60 days after the statement: unlimited liability for unauthorized transfers that happen after that window closes.

The jump from $50 to potentially unlimited is why debit card fraud needs same-day action. If a hospitalization, travel, or similar circumstance kept you from reporting on time, the law requires your bank to extend these deadlines for a reasonable period.⁸

Build Your Evidence Before You File

Banks reject disputes for weak evidence more often than for the wrong legal theory. Before you contact anyone, pull together:

Transaction details: exact date, dollar amount to the cent, merchant name as it appears on your statement, and any transaction or reference ID.
Proof you tried to work it out with the merchant. Dated emails, chat transcripts, call logs, or screenshots. For quality-of-goods disputes this isn’t optional, because federal law requires a good-faith attempt before the issuer has any duty to step in.⁴
Product or service evidence: photos of damaged goods, screenshots of the advertisement next to what arrived, or records showing a service was never performed.
Cancellation confirmations. For subscription charges that kept billing after you canceled, the confirmation email plus a screenshot of the later charge is the single strongest piece of evidence.

For debit card point-of-sale disputes, your bank may ask for a copy of the sales receipt to confirm the transfer amount matched your purchase.³ Having it ready keeps the clock from running out during back-and-forth.

How to Submit the Dispute

Most banks now have a dispute button next to each transaction in the online portal or mobile app. If your issuer’s billing rights statement accepts electronic notices, filing this way satisfies the legal requirement and gives you a timestamped record.⁶ Upload your supporting documents in the same session so they attach to the same claim.

If you prefer paper, or your bank’s disclosure doesn’t explicitly accept electronic disputes, send a letter by certified mail with return receipt. Use the billing inquiries address on your statement, not the payment address. The return receipt is what proves your notice arrived inside the 60-day window if the bank later says you filed late. Include your account information, the disputed amount, a clear description of the error, and copies of your supporting documents. Keep the originals.⁵

Some banks accept disputes by phone. If you go that way, write down the representative’s name, the date and time, and the claim reference number. A phone dispute leaves the weakest paper trail, so follow up with a written or electronic confirmation.

What Happens After You File

For credit card disputes, federal law gives the creditor two deadlines. It must send written acknowledgment within 30 days, unless it resolves the whole dispute in that same window. It must then complete the investigation within two billing cycles, and never more than 90 days total.⁵

While the investigation runs, the creditor can’t try to collect the disputed amount or report it as delinquent, as long as you keep paying the undisputed portion of your bill. Many issuers post a temporary credit during the review, but for credit cards that’s a courtesy, not a legal requirement.⁶ Debit works differently. Regulation E requires provisional credit within 10 business days if the bank hasn’t finished its investigation by then.

If the bank rules in your favor, it corrects your account and refunds any finance charges that accrued on the disputed amount. If it rules against you, it must explain why in writing and provide copies of the evidence it relied on if you ask for them.⁵ The original charge then stands, and any held finance charges become due.

Your Credit During the Dispute

One protection often missed: while the dispute is open, the creditor cannot report the disputed amount as delinquent to the credit bureaus, as long as you keep making the minimum payment on the rest of your balance.⁵ Filing a legitimate dispute does not hurt your credit. What hurts it is ignoring the charge entirely, missing payments on the undisputed balance, or not paying promptly after a denial.

If the Bank Denies Your Dispute

A denial isn’t automatically the end. Start by requesting copies of the documentary evidence the bank used. Sometimes the merchant’s rebuttal is thin and the bank sided with it anyway, or the bank misread what you were claiming.

You can then submit a written response explaining why you still disagree. At this point the creditor is allowed to report the amount as delinquent, but it must also notify the credit bureaus that you dispute the charge and must promptly report any eventual resolution.⁵

CFPB Complaint

If you believe the bank mishandled the dispute or violated its legal obligations, file a complaint with the Consumer Financial Protection Bureau. The complaint goes directly to the company, which generally has 15 days to respond, with a final response possible within 60 days. You can file online at consumerfinance.gov or by phone at (855) 411-2372.⁹ Include every relevant date, amount, and copy of your communications with the bank. You get one submission per issue, so don’t hold anything back.

Small Claims Court

For larger losses, you can sue the merchant directly in small claims court. Filing fees and claim limits vary by jurisdiction, with most caps falling between $5,000 and $10,000. This route works best when your documentation is strong and the merchant simply refused to cooperate.

Don’t File a Chargeback You Know Is False

Disputing a charge for goods you received exactly as described, sometimes called friendly fraud, has real consequences. Banks and merchants track the pattern. At the mild end, your bank may close your account and decline to open you a new one, and merchants share fraud data with card networks that can flag you across retailers. At the serious end, deliberately using a card to obtain things of value through false disputes is a federal crime. Fraud involving access devices can carry up to 10 years in prison for a first offense when the amount exceeds $1,000 in a one-year period.¹⁰ Criminal prosecution for one-off chargeback fraud is rare, but merchants increasingly file civil suits to recover high-value losses, and they win them when the evidence is clear.
