How to File a Chargeback: Evidence, Deadlines, and Denials

To file a chargeback, contact the merchant first to try for a refund, then submit a written dispute to your card issuer within 60 days of the statement date showing the charge, along with documentation that supports your claim. The issuer investigates, the merchant gets a chance to respond, and you get a decision within a timeframe set by federal law. The rules differ depending on whether you used a credit card or a debit card, and the deadlines are strict.

Start With the Merchant

Banks generally expect you to try resolving the problem with the seller before you escalate. Call or email the merchant, explain what went wrong, and ask for a refund or replacement. Put it in writing when you can so you have a record.¹

Save every email, every chat transcript, and notes from any phone call with the date and what was said. If the merchant refuses, offers something that doesn’t fix the problem, or simply never writes back, you’ve done your part. That paper trail shows your bank the chargeback is a last resort, not a shortcut around a return policy.

Gather Your Evidence Before You File

Chargebacks are won or lost on documentation. Before you open the dispute form, pull together:

Transaction details: the date, the merchant name exactly as it appears on your statement (often different from the storefront name you know), and the exact amount including tax and shipping.
Receipts and order confirmations, invoices, shipping tracking numbers, and any authorization or reference code from your receipt. The reference code helps the bank pull up the specific transaction.
Evidence of the problem itself. For a wrong or damaged item, photos next to screenshots of the original listing. For non-delivery, tracking information showing the package never arrived or went to the wrong address.
Your communications with the merchant, with dates.

Most banks accept uploads through their online dispute portal or mobile app, usually reached from the transaction detail screen in your account history. Have the files ready before you start so you aren’t hunting for a screenshot while a session clock ticks down.

How to Submit the Dispute to Your Issuer

For a credit card billing error, Regulation Z technically requires a written notice sent to a specific billing inquiries address printed on your statement, not a phone call.² If your issuer’s billing rights notice says it accepts electronic submissions, filing through the online portal or app satisfies the written-notice requirement. Most major issuers now do, but check the billing rights statement to confirm.

If you mail a paper dispute, send it certified with return receipt so you have proof of the date it arrived.¹ Send copies, not originals. Keep a copy of everything you submit, plus any confirmation number the bank gives you.

Debit card disputes under Regulation E are more flexible on format. You can notify the bank orally or in writing. But the bank is allowed to require written confirmation within 10 business days of an oral report, and if you don’t send it, the bank may not be required to provisionally credit your account while it investigates.³ Writing it down fast is the better move either way.

Your written notice should include your name and account number, the transaction date and amount, the merchant name, a clear description of what’s wrong, and the dollar amount you’re disputing.

The 60-Day Deadline

For a credit card billing error, you have 60 days from the date the issuer sent you the first statement showing the charge to get your dispute in.² The same 60-day window applies to debit card error notices under Regulation E.³

What counts as a billing error under Regulation Z is broad: unauthorized charges, charges for goods you didn’t accept or that weren’t delivered as agreed, duplicate charges, and computational mistakes on your statement.² A shipment that looks nothing like what was advertised fits.

Miss the 60 days and you lose the formal dispute rights these laws give you. The issuer may still look into it voluntarily, but it isn’t required to.

What You Owe While the Bank Investigates

Credit cardholders get real protection during the investigation. You don’t have to pay the disputed amount or finance charges tied to it, and the issuer can’t try to collect that portion of your balance.² If you’re on autopay, the issuer must stop pulling the disputed amount as long as you filed at least three business days before the scheduled payment. Keep paying the undisputed portion of your bill so you don’t rack up late fees on everything else.

The issuer also can’t report you as delinquent on the disputed amount while the investigation is open. It can note on your credit report that the amount is in dispute, but not that you’re behind. It may reduce your available credit limit by the disputed amount, so expect your available balance to dip for a while.

For debit card disputes, the mechanics are different. If the bank can’t finish investigating within 10 business days, it must provisionally credit your account for the disputed amount within those 10 business days so you have access to the money while the investigation continues.³ The bank may hold back up to $50 of that credit if it reasonably believes the transfer was unauthorized. If the bank later determines no error occurred, it can reverse the provisional credit after notifying you.

How Long the Investigation Takes

Credit Card Disputes

Your issuer must acknowledge your dispute in writing within 30 days of receiving it, unless it resolves the whole thing within that same 30 days.² From there, the issuer has two complete billing cycles to reach a final decision, capped at 90 days from when it received your notice. During this window the merchant is contacted and given a chance to respond with evidence that the charge was legitimate.

Debit Card Disputes

The bank must complete its investigation within 10 business days of receiving your error notice and report the results within three business days after finishing.³ If it needs more time, it can extend to 45 days total, but only if it provisionally credits your account within the initial 10 business days and gives you full access to the funds. The bank must tell you the provisional credit amount and date within two business days of applying it.

If the Decision Goes Your Way, or Doesn’t

If the bank sides with you on a credit card dispute, it must correct the error and credit back any finance charges that accrued on the disputed amount.² On a debit card, any provisional credit becomes permanent and the bank corrects the error within one business day of its determination.³

If a credit card dispute is denied, the issuer must send a written explanation and then give you a normal grace period to pay the amount without extra finance charges stacking up.⁴ On a debit card, the bank reverses any provisional credit, but must give you at least five business days’ notice before pulling the funds back.

What to Do if Your Chargeback Is Denied

A denial doesn’t have to be the end. You can file a complaint with the Consumer Financial Protection Bureau, which forwards it to your bank and requires a response. Companies typically respond within 15 days, and the CFPB allows up to 60 days for more complex matters.⁵ File online at consumerfinance.gov/complaint or call (855) 411-2372. The CFPB doesn’t decide individual disputes, but the complaint creates a formal record and often prompts a second look.

If the dollar amount justifies it, small claims court against the merchant is another option, with filing fees that vary widely by jurisdiction.

Don’t File a Chargeback You Can’t Support

Filing a chargeback on a legitimate charge because you have buyer’s remorse or want to dodge a return policy is fraud. Banks and merchants track chargeback patterns. Your card issuer may close your account. Merchants can and do blacklist customers who file disputes, cutting off future purchases. In extreme cases involving large amounts or repeated abuse, false chargebacks can expose you to civil suits from the merchant or even criminal wire fraud charges, though prosecution is rare.

The chargeback process exists for situations where something genuinely went wrong. When you have a real dispute, following the steps above, documenting carefully, and meeting the deadlines gives you serious leverage.
