How to Dispute a Transaction: Credit, Debit, and P2P Transfers

To dispute a credit or debit card transaction, contact the merchant first, then notify your bank: in writing within 60 days of the statement for a credit card, and by phone or in writing as fast as possible for a debit card. Which law protects you depends on the card. Credit card billing errors fall under the Fair Credit Billing Act.¹ Debit cards and other electronic transfers fall under the Electronic Fund Transfer Act and Regulation E, which has shorter deadlines and higher potential liability if you delay.²

Try the Merchant First

For most disputes, especially undelivered goods, duplicate charges, or canceled subscriptions, the merchant is the fastest route. Many businesses will refund or correct the charge without a bank getting involved.

Trying the merchant is also sometimes legally required. If your credit card dispute is about the quality of goods or services rather than a straightforward billing error, federal law requires a good-faith attempt to resolve it with the merchant before you can assert the claim against the card issuer.³ A phone call or email is enough. Keep a record: your bank will want to see you tried.

Gather Your Documentation

Before you file, pull together everything a bank might want to see:

The exact date, dollar amount, and merchant name as they appear on your statement.
Receipts, order confirmations, or shipping tracking numbers showing what you were supposed to receive.
Return tracking numbers and confirmation the merchant got the item back.
Cancellation records for subscriptions: screenshots, confirmation emails, or notes from phone calls.
Emails, chat transcripts, or call notes from your attempts to resolve the problem with the merchant.

Banks often pause investigations while waiting on more information from the account holder, and that pause can eat into your statutory deadlines. Have this ready before you file.

File the Dispute With Your Bank

Credit Card Disputes

Under the Fair Credit Billing Act, the notice must be in writing and must include your name and account number, a description of the charge you believe is wrong, the dollar amount, and the reason you think it is an error.¹ It must reach the issuer within 60 days of the date the statement containing the charge was sent.⁴

Send it to the address your issuer designates for billing inquiries, which is not the same as the payment address. Look for a “billing inquiries” or “billing disputes” address on your statement or on the back of your card. Most issuers also accept disputes through their app or online portal, and that satisfies the written notice requirement. If you mail a letter, use certified mail with a return receipt so you can prove it arrived within the deadline. Keep copies of everything, and save any digital confirmation as a PDF.

Debit Card and Electronic Transfer Disputes

For debit cards and other electronic transfers, Regulation E lets you notify your bank either orally or in writing.⁵ A phone call to customer service can start the investigation. Your bank can require written follow-up within 10 business days, though. If it asks for that and you don’t provide it, the bank does not have to provisionally credit your account during any extended investigation.

Speed matters far more with debit than with credit, because your liability grows the longer you wait. Report unauthorized activity the moment you spot it.

How Long the Investigation Takes

Credit Cards

The issuer must acknowledge your dispute in writing within 30 days of receiving it. It then has two full billing cycles, but no more than 90 days, to complete the investigation and either correct the error or explain why the charge is valid.⁴

During the investigation, most issuers apply a provisional credit for the disputed amount. You are not required to pay the disputed portion, and any related finance charges or late fees on that amount are suspended.⁴ You still need to pay the rest of your bill on time. Withholding the whole payment because of one disputed charge can trigger late fees on everything else.

Debit Cards

The bank must investigate and determine whether an error occurred within 10 business days of receiving your notice. If it finds an error, it must correct it within one business day and report the results to you within three business days.⁵

The bank can extend the investigation to 45 days, but only if it provisionally credits your account within 10 business days, notifies you of that credit within two business days of applying it, and gives you full access to the funds while the case is open. For point-of-sale debit transactions, the extended window is 90 days.⁵ If the bank finds no error, it can reverse the provisional credit after giving you at least three business days’ notice and an explanation.

What You Could Owe for Unauthorized Charges

Credit Cards

Your legal liability for unauthorized credit card charges is capped at $50, no matter when you report it, as long as the issuer gave you notice of the potential liability and a way to report unauthorized use.⁶ Most major issuers voluntarily offer zero-liability policies on top of that, but $50 is the statutory floor.

Debit Cards

Debit card liability is tiered, and every day counts:

Report within 2 business days of learning of the loss or theft, and your liability is capped at $50 (or the amount of unauthorized transfers before you notified the bank, whichever is less).²
Between 2 and 60 days, liability rises to a maximum of $500, including any unauthorized transfers after the two-day window that the bank can show would not have happened if you had reported sooner.²
After 60 days from the statement date, you can be liable for the full amount of unauthorized transfers that happen after that window closes and before you notify the bank.²

A stolen credit card number carries a maximum $50 risk. A stolen debit card that goes unreported for more than 60 days can drain your checking account with no legal obligation on the bank to return the money. Reviewing your statements regularly is the single best way to keep your exposure small.

Your Credit Report and Autopay During a Credit Card Dispute

While a credit card dispute is pending, the issuer cannot report the disputed amount as delinquent to any credit bureau, and it cannot threaten to.⁷ It can note the amount is “in dispute,” which alone does not damage your credit score. The issuer also cannot accelerate your debt, restrict your account, or close it solely because you filed a good-faith dispute.⁴ These protections cover only the disputed amount. Other unpaid balances on the same card can still be reported delinquent and sent to collections as usual.

If you use autopay, the issuer must stop deducting the disputed amount from your bank account, as long as you filed the dispute at least three business days before the next scheduled payment.⁴

When the Complaint Is About Quality

Billing errors and quality complaints are handled differently. Unauthorized charges, wrong amounts, and goods never delivered are billing errors, covered by the dispute process above. If the item arrived but was not what you expected, or the service was performed poorly, that falls under a separate rule called “claims and defenses,” and it applies only to credit cards.⁸

Under that rule, you can withhold payment from the issuer for an unsatisfactory purchase, but only if all three conditions are met:

The $50 and 100-mile limits fall away when the card issuer is also the seller, controls the seller, or solicited the transaction through a mail or online offer.⁸ The maximum you can withhold is the amount still outstanding on that transaction when you notify the issuer, so paying the charge off in full before raising the claim can limit your rights. Debit card quality complaints depend on the merchant’s return policy or on voluntary protections from your bank or the payment network.

Zelle, Venmo, Cash App, and Other P2P Transfers

Regulation E covers peer-to-peer payment services too. The CFPB has said P2P providers count as “financial institutions” under Regulation E when they hold a consumer’s account or issue an access device and agree to provide electronic fund transfer services.⁹ They must investigate on the same 10-business-day (or extended 45-day) timeline and provide provisional credit when required.

For services like Zelle that run through your bank rather than holding a separate account, your bank is the institution responsible for investigating. File through the bank rather than the app’s customer service.

One important boundary: Regulation E covers unauthorized transfers, meaning transactions someone else made without your permission and from which you got no benefit. If you sent money to someone who turned out to be a scammer, the transfer was technically authorized by you, even though it was obtained by fraud. Some banks and P2P providers have expanded voluntary fraud protections in this area, but federal law does not guarantee reimbursement for payments you initiated yourself.

If the Bank Denies Your Dispute

A denial must come with a written explanation, and if you ask, copies of the documents the bank relied on.¹ Any provisional credit that was applied will be reversed.

You still have options. If you have new evidence, ask the bank to reopen the case. You can also file a complaint with the Consumer Financial Protection Bureau, which enforces both Regulation Z for credit cards and Regulation E for debit cards. For larger amounts, a consumer protection attorney can walk you through state-law options, since some states offer protections beyond federal law.
