How Do I Dispute a Transaction? Deadlines, Notice, and Appeals

To dispute a transaction, send your bank or card issuer a written notice within 60 days of the statement date identifying the charge, the amount, and why it’s wrong, then back the notice with receipts, emails, and any proof you have. That 60-day window is set by federal law and it applies to both credit cards and debit cards, but the consequences for missing it are far worse on the debit side. Everything else about how to dispute a transaction — where to send the notice, what to include, how long the bank has to answer — flows from that first step.

The 60-Day Clock

You have 60 days from the date the statement showing the charge was sent to you (not the date you opened it) to notify your bank or issuer.¹ Same window for debit card errors under a different statute.² Miss it on a credit card dispute and you lose the formal protections of the Fair Credit Billing Act, though your maximum liability for an unauthorized charge is still capped at $50 by a separate provision, and most major issuers waive even that under voluntary zero-liability policies.³

Debit cards are different, and this is where speed actually costs you money. If a card is lost or stolen and used for unauthorized transfers, your liability depends on how fast you report:

Report within 2 business days of learning about the loss or theft, and your liability caps at $50.
Report after 2 business days but within 60 days of the statement, and liability rises to as much as $500.
Report after 60 days from the statement date, and there is no cap at all on unauthorized transfers that happen after that window closes.

Those tiers apply when a lost or stolen access device is involved.⁴ For other debit card statement errors, the 60-day reporting window still governs.⁵ Review your statements monthly and report anything you don’t recognize the day you spot it.

Try the Merchant First (Sometimes)

If you’re disputing the quality of goods or services on a credit card — the thing arrived broken, wasn’t what was promised, services weren’t what you paid for — federal law requires a good-faith attempt to resolve it with the merchant before the card issuer has to get involved. That requirement kicks in when the transaction exceeded $50 and happened either in your home state or within 100 miles of your billing address.⁶ Those limits fall away if the merchant and the card issuer are the same company, if one controls the other, or if the issuer helped solicit the sale through a mail offer.

This rule does not apply to charges you never authorized or goods never delivered — those go straight to the issuer. For quality disputes, save your emails, chat transcripts, and notes from phone calls. If the merchant stops responding or refuses to make it right, that paper trail becomes evidence for your bank.⁷

What to Put in Your Dispute Notice

The statutory minimum has three pieces: your name and account number, a statement that your bill contains an error along with the dollar amount, and the reasons you believe the charge is wrong.¹ The same structure works for debit card error notices.² That’s the floor. Winning the dispute depends on what you add.

Pull the transaction date and the merchant name exactly as they appear on your statement. Merchant names on statements often don’t match storefronts, and getting that wrong creates confusion. Attach copies of sales receipts, shipping confirmations, tracking numbers, return receipts, cancellation confirmations, or screenshots of the merchant’s refund policy. If you already tried to resolve things with the merchant, include those emails or a dated summary of phone calls.

Keep originals; send copies. If you file online, screenshot the confirmation page. A tidy, well-organized package tells the investigator you’ve done your homework, and it tells the merchant that fighting back isn’t going to be easy.

Where to Send It

For a credit card dispute, the law requires written notice delivered to the billing inquiry address your issuer discloses — not the payment address.¹ Those are usually different places. Check the back of your statement or your issuer’s website. A dispute sent to the payment center can be treated as if you never filed. Certified mail with a return receipt gives you proof of the delivery date, which is the document that saves you if the issuer later claims your notice arrived outside the 60-day window.

Debit card disputes work differently. The financial institution has to accept both oral and written error notices.² But the institution can require written confirmation within 10 business days of an oral report, and if you don’t provide it in time, the bank doesn’t have to issue a provisional credit. Call if you need to, then follow up in writing the same day.

Most banks and card issuers now let you file through their app or website. Select the transaction, choose a reason, upload documents, submit. Save the confirmation page with the case number. Online filing is convenient but doesn’t produce the same delivery proof as certified mail, so keep your own copies of everything you send and screenshots of what you upload.

What Happens After You File

Credit card and debit card investigations run on different clocks.

Credit Card Timeline

The issuer must acknowledge your dispute in writing within 30 days of receiving it, unless it’s already resolved by then. The full investigation must finish within two complete billing cycles, and in no event more than 90 days from the date your notice arrived.¹ During the investigation, the issuer cannot try to collect the disputed amount or report it as delinquent. If the investigation confirms the error, the issuer has to correct the account and refund any finance charges that accrued on the wrong amount. If it concludes the charge was valid, it must send you a written explanation and, on request, the documents it relied on.

Debit Card Timeline

The bank has 10 business days from receiving your notice to investigate and decide whether there was an error. It can extend that to 45 days, but only if it issues a provisional credit to your account within the original 10 business days.⁸ New accounts, point-of-sale transactions, and foreign-initiated transfers can get up to 90 days of investigation time.⁵ You have full use of the provisional credit while the investigation runs. If the bank ultimately decides no error occurred, it has to tell you before pulling the credit back and let you request the documents it used.

Keep Paying Everything Else

You don’t have to pay the disputed amount while the case is open. You do have to pay the rest of your bill, including finance charges on the undisputed balance.⁷ Skipping the full payment because one line item is in dispute is one of the fastest ways to turn a billing error into a credit score problem. The creditor can note that the amount is in dispute but cannot report it as past due or use the threat of credit damage as a collection tactic.⁹

If Your Dispute Is Denied

A denial comes with a written explanation of how much you owe, why, and when it’s due. If the issuer had previously given you a grace period on the disputed amount, it has to give you the same grace period after the denial so you can pay without immediately accruing finance charges.⁷ If you ultimately owe the amount, you’ll owe the finance charges that built up during the investigation too.

Request copies of every document the issuer used to reach its decision. Merchant evidence is often thin or doesn’t actually address what you complained about. If you think the denial is wrong, you can file a complaint with the Consumer Financial Protection Bureau, which enforces both the Fair Credit Billing Act and the Electronic Fund Transfer Act. Small claims court is another route; filing fees are low, you don’t need a lawyer, and the dollar limits generally run from around $6,000 to $20,000 depending on the state.

If the Bank Breaks the Rules

The procedural rules have teeth. A credit card issuer that misses the two-billing-cycle deadline, tries to collect the disputed amount during the investigation, or threatens to report you as delinquent while the dispute is open forfeits the right to collect the first $50 of the disputed amount, even if the underlying charge turns out to be valid.¹ That forfeiture is automatic.

On the debit side, a bank that fails to issue a required provisional credit or doesn’t complete its investigation on time can face treble damages (three times the amount of the error) in an individual lawsuit under the Electronic Fund Transfer Act.² If your bank is dragging its feet or ignoring the deadlines, mentioning those penalties in your next call tends to focus attention.
