How Do Credit Card Billing Disputes Work?

Credit card billing disputes are governed by the Fair Credit Billing Act, which gives you the right to challenge a charge in writing, withhold payment on the disputed amount, and require your card issuer to investigate. The core rule to remember: you have 60 days from the date the issuer sends the statement containing the error to get a written dispute to the address listed for billing inquiries.¹ Miss the window and the issuer has no legal duty to do anything about it.

What Counts as a Billing Error

The law defines billing errors in specific categories. A disagreement over quality or buyer’s remorse is not one of them. You can dispute:

Charges you didn’t authorize.
Charges for the wrong amount or that don’t match what you agreed to pay.
Charges for goods or services you never received or didn’t accept.
Math or posting mistakes, like a transaction billed twice.
Payments or credits the issuer failed to post.
Failure to deliver the statement to your current address, as long as you gave the issuer your change of address at least 20 days before the billing cycle closed.

These categories come directly from the statute.¹ Complaints about goods that arrived but were defective or not as described follow a separate track, covered further down.

The 60-Day Deadline

The 60 days runs from the day the issuer transmits the first statement containing the error. It does not run from when you spotted the problem or when the transaction occurred.¹ If a fraudulent charge sits on an old statement for three months before you catch it, the issuer is no longer required to follow the dispute process. Many will investigate anyway as a courtesy, but courtesy is not the same as a legal obligation.

Review every statement when it arrives. This deadline is the easiest way to lose rights you otherwise would have had.

How to File the Dispute

A phone call does not count. The Fair Credit Billing Act requires a written notice. Many issuers now accept disputes through their online portals, which generate a written record. If you want the strongest paper trail, send a letter by certified mail with return receipt.

Send it to the address the issuer has designated for billing inquiries, which is almost never the same as the payment address. The correct address appears on your monthly statement, usually labeled “Send billing inquiries to” or similar. A dispute that arrives at the payment processing center may not count as received, and if it isn’t received at the right place, the issuer’s duty to investigate may never kick in.²

The notice needs three things: information identifying you and your account, a statement that you believe the bill contains an error along with the dollar amount, and the reasons you think it’s wrong.¹ A plain sentence works. Something like “I am disputing a $347 charge from XYZ Merchant on my January 15 statement because I never made this purchase” covers all three. Attach anything useful: receipts, return tracking numbers, emails with the merchant.

What the Issuer Must Do

Once a valid dispute arrives, two clocks start running. The issuer must send a written acknowledgment within 30 days, unless the whole dispute is resolved in that time. And the investigation must be completed, with either a correction or a written explanation, within two complete billing cycles. That period can never exceed 90 days.²

During the investigation, the issuer cannot try to collect the disputed amount. No lawsuits, no liens, no dunning letters about the disputed portion. You still owe the rest of the bill, and minimum payments on undisputed charges still apply. The disputed amount is effectively frozen while the issuer looks into it.²

Protection for Your Credit Score

While the dispute is pending, the issuer cannot report the disputed amount as delinquent to a credit bureau. It also cannot threaten your credit rating as a way to pressure you into paying.³ The issuer cannot close your account or accelerate the debt just because you exercised your dispute rights.²

How the Investigation Ends

If the Issuer Agrees With You

When the investigation confirms a billing error, the issuer must correct your account and credit back any finance charges or late fees that piled up on the incorrect amount. The correction must be communicated to you in writing. If you ask, the issuer also has to provide documentation of your account activity.¹

If the Issuer Says the Bill Stands

If the issuer concludes the charge was accurate, it must send you a written explanation. You can request copies of the documentary evidence it relied on, and the issuer must provide them.¹ Ask for them. The underlying records sometimes show the investigation was thin.

After telling you the bill is correct, the issuer has to give you at least 10 days, or your normal grace period if that’s longer, to pay before reporting the account as delinquent. Finance charges that built up on the disputed amount during the investigation may now be owed. If you still believe the charge is wrong, you can send another written notice within that payment window stating the amount remains in dispute. The issuer can then report the account as delinquent, but it must also report that the amount is disputed and tell you the name and address of each credit bureau it notified.³

Defective Goods or Services Follow a Different Track

If you received the goods but they were defective, damaged, or not what the merchant promised, that is not a billing error in the technical sense. A separate section of the Fair Credit Billing Act lets you raise against your card issuer the same claims and defenses you could raise against the merchant, but with conditions.⁴

The transaction must exceed $50, and the purchase must have occurred in your state or within 100 miles of your billing address. Those limits drop away if the merchant is the card issuer itself, is controlled by the issuer, is a franchisee of the issuer, or if the issuer solicited the sale by mail.⁴

There is also a prerequisite that catches people off guard. For quality-of-service disputes, you must first make a good-faith attempt to work the problem out with the merchant before going to your card issuer. Standard billing-error disputes have no such requirement. Keep records of your attempts to reach the merchant.

The amount you can recover this way is capped at the credit still outstanding on that transaction when you first notify the issuer. If you’ve mostly paid the balance down, there may not be much left to withhold.

Unauthorized Charges and the $50 Cap

A separate federal provision limits your personal liability for unauthorized credit card use to $50, and only if the card is an accepted card, the issuer gave you notice of potential liability, and the unauthorized use happened before you reported the loss or theft. Most major issuers advertise zero-liability policies that go beyond this, but $50 is the floor set by law. If any of the conditions for liability isn’t met, you owe nothing.⁵ This provision is distinct from the dispute process, though the two often overlap when unauthorized charges hit your statement.

If the Issuer Doesn’t Follow the Rules

An issuer that fails to comply with the investigation requirements forfeits the right to collect the disputed amount and any finance charges tied to it, up to a maximum of $50. That forfeiture applies even if the underlying charge was legitimate.¹

You can also sue. For violations involving an open-end credit plan like a credit card, you can recover actual damages plus twice the amount of any finance charge connected to the transaction, with a statutory minimum of $500 and a maximum of $5,000, plus attorney’s fees and costs if you prevail.⁶ The statutory minimum means you don’t have to prove a large financial loss for a case to be worth bringing. An issuer that ignores a dispute, reports you as delinquent during the investigation, or closes the account in retaliation has real exposure.
