What Happens When You Dispute a Charge With Your Bank?

When you dispute a charge with your bank, the bank freezes the transaction, opens an investigation on a legal clock, and either reverses the charge for good or puts it back on your account. Two federal laws set the rules: the Fair Credit Billing Act for credit cards and the Electronic Fund Transfer Act for debit cards. They protect you differently, and the deadlines are strict enough that missing one can wipe out your rights entirely.

The Deadlines That Decide Whether You’re Protected

Before anything else, check the calendar. Your ability to force the bank to investigate, and your exposure if the charges were fraudulent, both turn on how quickly you act.

Credit Cards

You have 60 days from the date your card issuer sends the statement containing the disputed charge to submit a written notice of the billing error. If you miss that window, the creditor has no legal obligation to investigate.¹ Your maximum liability for unauthorized credit card charges is $50. If the card number was stolen but the physical card wasn’t, such as in an online transaction, your liability drops to $0.²

Debit Cards

Debit card deadlines carry steeper penalties. Your liability depends on how quickly you report the problem:

Within 2 business days of learning your card was lost or stolen: liability caps at $50.
After 2 business days but within 60 days of receiving your statement: liability can reach $500.
After 60 days from when your statement was sent: potentially unlimited liability for unauthorized transfers that occur after the 60-day window.

Review every bank statement promptly. If an unauthorized transfer appears and you don’t report it within 60 days, the bank can hold you responsible for every fraudulent charge that follows.³

In practice, Visa and Mastercard both offer zero-liability policies that often bring your real-world exposure below the federal floor, as long as you used reasonable care and reported the loss promptly. Commercial cards and unregistered prepaid cards are typically excluded.⁴⁵

How to File the Dispute

Have four pieces of information ready: the date of the transaction, the exact dollar amount, the merchant name as it appears on your statement, and the reason you’re disputing. Most banks let you file through their app or website by selecting the transaction and choosing “dispute” or “report a problem.” Filing electronically creates an immediate record and is usually the fastest route.

For debit card disputes, you can notify the bank orally or in writing. If you call, the bank may require a written confirmation within 10 business days. Skip that follow-up when it’s required, and the bank has no obligation to provisionally credit your account while it investigates.⁶

For credit card disputes, the Fair Credit Billing Act technically requires a written notice sent to the specific billing error address printed on your statement, not the general customer service address or the payment address. The statute does not explicitly recognize an online dispute filed through a bank’s portal as satisfying that requirement.¹ Most major issuers treat online disputes as valid, but for large amounts the safest approach is to file online for speed and also mail a written notice to the billing error address. That way your federal rights are preserved regardless of how the bank interprets its digital process.

You do not need to contact the merchant before filing with your card issuer. Regulation Z sets no such prerequisite for billing error claims involving goods or services that weren’t delivered as agreed.⁷

What the Bank Does Next

Once your notice is filed, the investigation timeline depends on which card you used.

Credit Card Investigations

The card issuer must acknowledge your written dispute within 30 days of receiving it, unless it resolves the issue in that same window. The issuer then has two complete billing cycles, and no more than 90 days from receiving your notice, to finish investigating.⁷

While the investigation is open, you are not required to pay the disputed amount or any related finance charges. The creditor cannot collect on that portion, cannot report it as delinquent to credit bureaus, and cannot accelerate your debt or close your account solely because you filed. The charge will still appear on your statement, marked as disputed, but no interest accrues on that portion in the meantime.⁸

Debit Card Investigations

Your bank must determine whether an error occurred within 10 business days of receiving your notice. If it confirms an error, it must correct it within one business day. If it needs more time, it can extend the investigation to 45 calendar days, but only if it provisionally credits your account within the initial 10-business-day window.⁹

The provisional credit must cover the full disputed amount, plus interest where applicable. If the bank believes the transfer was unauthorized and you reported the loss more than two business days after learning of it, the bank may withhold up to $50 from the provisional credit. The bank must tell you the credit amount and date within two business days of issuing it, and you get full use of those funds while the investigation continues.⁶

Certain transactions get the bank 90 calendar days instead of 45: point-of-sale debit card purchases, international transfers, and transactions on accounts open for fewer than 30 days.⁹

The Merchant’s Turn

When your bank reverses a charge, the merchant’s bank notifies the merchant and gives it a chance to submit evidence that the transaction was valid, such as delivery confirmations, signed receipts, or customer service records. If the merchant successfully challenges the reversal, the disputed amount can be charged back to your account.

Your Credit Report During a Dispute

While a credit card dispute is pending, the creditor cannot report the disputed amount as delinquent to any credit bureau. That protection lasts until the investigation concludes.⁸ Your account may carry a notation that a dispute is in progress, but that notation alone does not damage your score.

Debit card disputes don’t directly affect your credit report, because debit transactions aren’t extensions of credit. If a denied dispute leaves your checking account overdrawn and you don’t resolve the negative balance, the bank may report the account to a specialty consumer reporting agency.

If the Bank Denies Your Dispute

When the bank concludes that no error occurred, or that the error differed from what you described, it must send you a written explanation of its findings. For debit card disputes, the bank must also tell you that you can request copies of the documents it relied on, and provide them promptly if you ask.⁹ For credit card disputes, the creditor must explain how much you owe (including any finance charges that accrued during the investigation) and when payment is due.

If the bank had provisionally credited your debit card account, it will withdraw that credit after denying your claim. It must give you at least five business days’ notice before debiting the provisional amount, and it must tell you the date and amount of the debit. If you already spent those funds, the withdrawal can overdraw your account.

If the investigation found a billing error in a different amount than you claimed, the creditor must correct the actual error and credit your account for the correct amount, including any related finance charges.¹⁰

Where to Go After a Denial

A denial isn’t the end. You can file a complaint with the Consumer Financial Protection Bureau, which forwards it to the bank. Companies generally respond within 15 days, though some ask for up to 60 days for a final response. You’ll have 60 days to review the company’s answer and provide feedback.¹¹

You can also take the matter to small claims court. Filing fees typically run from about $30 to $75 depending on the jurisdiction and claim amount, and can run higher for larger claims. For a substantial sum, consulting an attorney about a civil lawsuit may be worthwhile.

Don’t File a Dispute You Know Is False

Filing a dispute for a charge you know was legitimate, sometimes called “friendly fraud” or “first-party fraud,” is not risk-free. Deliberately filing a false claim to recover money for goods or services you actually received can constitute bank fraud under federal law, punishable by fines up to $1,000,000, imprisonment up to 30 years, or both.¹² Banks track dispute patterns and may flag or close accounts that file unusual numbers of claims, and the merchant you disputed may bring its own civil claim for the cost of the goods or services.
