When you dispute a charge on your card, your issuer opens a federally regulated investigation that pauses your obligation to pay the disputed amount and must reach a decision within two full billing cycles, and never more than 90 days.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors The Fair Credit Billing Act also requires the issuer to acknowledge your dispute within 30 days of receiving it. During that window, the charge cannot be reported as delinquent to the credit bureaus, and the outcome turns on the evidence you and the merchant each put forward.
What Happens to Your Account While the Investigation Runs
Once your creditor receives the dispute, you can withhold the disputed amount without penalty. You still need to pay the undisputed portion of your bill to keep the account in good standing.2Consumer Compliance Outlook. Error Resolution and Liability Limitations Under Regulations E and Z
The creditor cannot report the disputed amount as delinquent to any credit bureau while the investigation is active, and it cannot threaten to do so because you challenged the charge.3Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports It can, however, apply the disputed amount against your credit limit, which may reduce your available credit until the matter closes. This is not the same as a provisional credit that puts money back into your pocket. For a credit card, the protection is simpler: you withhold, and the bank cannot punish you for it.
Finance charges continue to accrue on the disputed amount in the background. If the bank ultimately finds a billing error, it must credit back those finance charges along with the disputed amount itself. If the dispute is denied, you’ll owe the original charge plus whatever finance charges built up while the review was open.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
The Timeline You Can Expect
Two deadlines govern the issuer. It must send you written acknowledgment of your dispute within 30 days of receiving it, and it must complete the investigation and correct the account or explain its refusal within two complete billing cycles, capped at 90 days total.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors Most disputes wrap up well before the outer limit, but the bank is entitled to use the full window if the merchant’s evidence takes time to gather.
Filing the dispute itself has its own deadline. You have 60 days from the date the statement containing the error was sent to you. Miss that window and you lose your FCBA protections for that charge, even when the error is obvious.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors The clock runs from when the statement is sent, not from when you notice the problem.
What the Bank Actually Does Behind the Scenes
After opening the investigation, your issuer contacts the merchant’s bank through the card network. The merchant then has a response window, typically 20 to 45 days depending on the network’s rules.4Mastercard. How Can Merchants Dispute Credit Card Chargebacks If the merchant doesn’t respond in time, the dispute generally resolves in your favor by default.
When a merchant does respond, they submit evidence to counter your claim: signed delivery confirmations, records of a prior refund, authorization logs, or proof that you used the service. The bank’s analyst weighs what you provided against what the merchant sent back. They look at specifics. Did the merchant follow proper authorization procedures? Was the item actually delivered? Did the merchant attempt to resolve the issue directly before it escalated?
Thorough documentation on your end matters here. A vague complaint about “not getting what I expected” tends to lose to a merchant who can produce a signed receipt. Transaction dates, the merchant name as it appears on your statement, receipts, email confirmations, tracking numbers, and screenshots of any correspondence with the seller all strengthen your position.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
How the Investigation Ends
If the bank finds a billing error, it must correct the account, credit back any finance charges on the disputed amount, and send you written notice of the corrections.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
If it concludes no error occurred, it must send you a written explanation of why the charge is correct. You can request copies of the documentary evidence the bank relied on.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors The full balance then becomes due, including the finance charges that accumulated during the review. Before the creditor can report the amount as delinquent to a credit bureau, it must give you at least 10 days to pay.3Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports
Your Liability for Unauthorized Charges
If someone used your credit card without your permission, federal law caps your liability at $50, and only when specific conditions are met: the issuer gave you notice of your potential liability, provided a way to report the loss, and the unauthorized use happened before you notified them.5Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card Once you report the card lost, stolen, or compromised, you have zero liability for anything that follows. Most major issuers voluntarily go further than the statute and waive even the $50.
If Your Card Was a Debit Card, the Rules Are Different
Debit card disputes fall under the Electronic Fund Transfer Act and Regulation E, not the FCBA, and the consumer protections are consistently weaker. Liability for unauthorized transactions depends on how quickly you report: capped at $50 if you report within two business days of learning about the loss, up to $500 if you report after that but within 60 days of the statement, and potentially unlimited for transfers that occur after the 60-day window.6eCFR. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E)
Because a debit card dispute involves money already pulled from your checking account, the bank must issue a provisional credit if it needs more than 10 business days to investigate. The full investigation window is 45 days for most transactions and up to 90 days for point-of-sale transactions.7Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors If your dispute is about a debit card, assume the credit-card protections above do not apply.
A Note on Filing the Dispute the Right Way
The FCBA technically requires a written notice sent to your creditor’s billing inquiries address, which is different from the address where you send payments and is usually printed on the back of your statement. Most major issuers now accept disputes through online portals and phone calls, and those channels are fine for straightforward disputes. But the full statutory protection attaches to written notice at the correct address, so if the matter looks like it will become contested, send a letter by certified mail with return receipt.
The notice needs three things: your name and account number, a statement that you believe there is a billing error along with the dollar amount, and your reasons for believing it’s an error.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
One boundary worth flagging: complaints about the quality of goods you actually received (they arrived, but they’re broken or nothing like the listing) follow a separate legal path with extra requirements, including a good-faith attempt to resolve the issue with the merchant first and, in some cases, geographic and dollar limits on the transaction.8Office of the Law Revision Counsel. 15 USC 1666i – Assertion by Cardholder Against Card Issuer of Claims and Defenses Arising Out of Credit Card Transaction The billing-error process described above covers unauthorized charges, wrong amounts, and undelivered goods.
What to Do If Your Dispute Is Denied
A denial isn’t necessarily the end. Request the documentary evidence your bank relied on; you’re entitled to it under the FCBA.1Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors Sometimes the merchant’s rebuttal contains errors or gaps you can push back on.
If you still believe you’re right, you can write to your creditor stating that you continue to dispute the amount. The creditor can then report the amount as delinquent, but it must also report that you dispute the charge and notify you of every entity it reports to.3Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports If the dispute is later resolved, the creditor must update every party it previously notified.
You can also file a complaint with the Consumer Financial Protection Bureau. The online process takes about 10 minutes, and you can attach up to 50 pages of supporting documents. The CFPB forwards your complaint to the company, which generally responds within 15 days.9Consumer Financial Protection Bureau. Submit a Complaint Companies take these seriously because they become part of a public database. You can also call (855) 411-2372 between 9 a.m. and 6 p.m. ET, Monday through Friday.
For substantial amounts, or when the creditor violated its FCBA obligations during the investigation itself, the statute provides for actual damages plus statutory damages up to twice the finance charge, along with attorney’s fees. That framework makes consulting a consumer protection attorney economically viable in cases where the bank clearly mishandled the process.
