Yes, you can dispute a charge with your bank, and federal law requires the bank to investigate when you do. The path splits depending on the card you used. Credit card disputes run under the Fair Credit Billing Act, which caps your liability for unauthorized charges at $50 and gives the issuer up to 90 days to resolve the problem. Debit card disputes run under the Electronic Fund Transfer Act, and there your protection depends almost entirely on how quickly you report the charge.
Charges You Can Actually Dispute
Not every charge you regret qualifies. The Fair Credit Billing Act lists specific categories of credit card billing errors you can challenge:
- Unauthorized charges, meaning someone used your card or card number without permission.
- Wrong amounts, like a $250 charge for a $25 purchase.
- Goods or services you paid for but never received, or that arrived materially different from what was described.
- Payments or returns the creditor failed to credit to your account.
- Math and accounting mistakes, including miscalculated interest or a payment applied to the wrong billing period.
- Statements sent to the wrong address, provided you gave the creditor your current address at least 20 days before the billing cycle ended.
- Charges you don’t recognize and want documented.
That last category is broader than most people realize. It covers the common situation where a merchant’s billing name doesn’t match the storefront name you’d recognize.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Debit card rules are narrower. The Electronic Fund Transfer Act covers unauthorized transfers and errors on your account statement, including incorrect amounts, transfers you didn’t make, and the bank’s own computational mistakes. It does not give you the same leverage over quality-of-goods disputes with a merchant. If your debit card purchase arrives broken, your recourse runs through the merchant or through voluntary card network protections rather than through federal banking law.2Legal Information Institute (LII) / Cornell Law School. Electronic Funds Transfer Act
Why Credit Card Protection Is Stronger
If you have a choice between disputing on a credit card or a debit card, use the credit card. The protections are not equivalent.
Under the FCBA, your maximum liability for unauthorized credit card use is $50. There’s no sliding scale based on when you notice. Once you tell the issuer about an unauthorized charge, your exposure stops at $50 for anything charged before that notification.3Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card Most major networks go further with voluntary zero-liability policies that eliminate even that $50, though those policies don’t apply to certain commercial and prepaid cards.4Visa. Visa Zero Liability Policy
Debit card liability rises with delay:
- 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 your liability can reach $500.
- Report after the 60-day window from your statement, and you can be responsible for the full amount of unauthorized transfers that occur after that window closes.
That last tier is the one nobody expects until it lands on them. If several months of statements go unreviewed while someone drains your checking account, federal law does not guarantee you’ll get that money back.5Office of the Law Revision Counsel. 15 USC 1693g – Consumer Liability
How to File the Dispute
Credit Cards
The FCBA requires a written notice to your creditor within 60 days after the statement containing the error was sent to you. Send it to the address the creditor designated for billing inquiries, not the payment address. Your notice needs your name, account number, the amount you believe is wrong, and the reason you think it’s an error.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Most issuers now accept disputes through their app or website, and the online forms collect what the statute requires. If the amount is significant or you expect the issuer to push back, certified mail with return receipt gives you a timestamped record that the issuer received your notice, and when. That timestamp matters if the issuer later argues you missed the 60-day window.
You don’t have to pay the disputed amount, or interest and fees on it, while the investigation runs. You still owe the undisputed balance.
Debit Cards
Under the EFTA, you have 60 days from the date the bank sent you the statement showing the error. You can notify the bank orally or in writing, but if you call, the bank can require written confirmation within 10 business days. Pay attention to that request: if the bank asks for written confirmation and you don’t send it, the bank is not required to provisionally credit your account and doesn’t face the usual penalties for slow resolution.6GovInfo. 15 USC 1693f – Error Resolution
How Long the Bank Has to Respond
Credit Card Timeline
The creditor must send you a written acknowledgment within 30 days of receiving your notice, unless the entire dispute is resolved within that window. From there, the creditor has two complete billing cycles to finish the investigation, capped at 90 days from the receipt of your notice. At the end, the creditor either corrects your account and removes related finance charges, or explains in writing why the original charge stands.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
While the investigation is open, the creditor cannot try to collect the disputed amount, charge interest or late fees on it, or report your account as delinquent to the credit bureaus over the disputed amount. If the investigation confirms you owe the money, the creditor still has to wait at least 10 days before reporting a late payment, which gives you time to catch up.7Federal Trade Commission. Fair Credit Billing Act
Debit Card Timeline
Debit card deadlines are tighter. The bank must complete its investigation within 10 business days of receiving your notice. If it can’t finish, it can extend to 45 days total, but only if it provisionally credits your account within those first 10 business days. That provisional credit includes interest where applicable, and you have full use of the funds while the investigation continues.8Consumer Financial Protection Bureau. Regulation E 1005.11 – Procedures for Resolving Errors
Two exceptions stretch these periods. Point-of-sale debit transactions extend the investigation window to 90 days rather than 45, which covers most everyday debit card use at stores and restaurants. For errors involving transfers within 30 days of your first deposit into a new account, the bank gets 20 business days instead of 10 and 90 days instead of 45.8Consumer Financial Protection Bureau. Regulation E 1005.11 – Procedures for Resolving Errors
If the Bank Denies Your Dispute
A denial isn’t the end of the process. Several options remain, and they work best in order.
Start by requesting the evidence. When a credit card issuer determines you owe the disputed amount, it must explain in writing why and how much, and you can request copies of the documents the issuer relied on.9Consumer Advice – FTC. Using Credit Cards and Disputing Charges Reviewing that file sometimes shows that the merchant submitted the wrong transaction record or that the investigation overlooked your documentation.
After you receive the explanation, you have the later of 10 days or the payment due date to challenge the results, submit additional evidence, or point out mistakes in the investigation. It’s a narrow window, and most people miss it because they don’t know it exists.
If you believe the bank failed to follow proper procedures, file a complaint with the Consumer Financial Protection Bureau. Keep it clear and concise, include key dates and amounts, and attach supporting documents up to 50 pages. Companies generally respond within 15 days, though complex cases can take up to 60. You then have 60 days to give feedback on the response.10Consumer Financial Protection Bureau. Submit a Complaint The complaint isn’t a lawsuit, but financial institutions tend to take these seriously because the Bureau tracks response rates and publishes complaint data.
Small claims court is a further option when the bank and merchant both refuse to move. Dollar limits vary by state, filing fees are modest, and you generally don’t need a lawyer.
Withholding Payment for a Merchant’s Failure
Separate from reporting a billing error, the FCBA lets you assert claims and defenses against your credit card issuer when a merchant fails to deliver what you paid for. If you bought a couch that arrived with broken legs and the merchant won’t fix it, you can withhold payment to the card issuer for the remaining balance on that charge. Conditions apply:
- You must have first made a good faith attempt to resolve the problem with the merchant.
- The original transaction must exceed $50.
- The purchase must have occurred in your home state or within 100 miles of your mailing address.
The dollar and geographic limits don’t apply when the merchant is the card issuer itself, is controlled by the issuer, or obtained the transaction through a mail or internet solicitation the issuer participated in. That last exception effectively covers most online purchases made through links or promotions tied to your card issuer.11Office of the Law Revision Counsel. 15 USC 1666i – Assertion by Cardholder Against Card Issuer of Claims and Defenses
The amount you can withhold is limited to the credit outstanding on that specific transaction when you first notify the issuer. If you’ve already paid most of it off, only the remaining balance is in play.
Don’t File a Dispute You Know Is False
Disputing a charge you know is legitimate, sometimes called friendly fraud or chargeback fraud, carries real consequences. Banks and card networks track dispute patterns, and a pattern of questionable disputes can lead to account closure. A closure tied to suspected fraud may be reported to ChexSystems, a consumer reporting agency that banks check before opening new accounts, and a ChexSystems record can make it difficult to open accounts elsewhere for up to five years. Merchants can also provide evidence during the investigation, ban you from future purchases, and pursue civil claims in egregious cases. None of this touches legitimate disputes filed in good faith, which is exactly what the system exists for.
