You spot a charge you do not recognize. Maybe it is a duplicate, or an item that never arrived. The first question is simple: how long do you have to act? The short answer is 60 days for the federal rule. But that is not the only clock, and the clocks do not start on the same day.
The federal 60-day window for billing disputes
The Fair Credit Billing Act (FCBA) covers billing disputes on open-end credit accounts, which is the legal term for credit cards and similar revolving accounts. The FTC enforces it. Under the Act, you have 60 days from the date a billing statement was sent to dispute certain charges over $50. Debit card transactions are not covered by this Act. The deadline here is for credit cards only.
Regulation Z is the Federal Reserve Board's rule that carries out the Truth in Lending Act, a law first passed in 1968. It sets the same core requirement. You tell the card issuer in writing within 60 days of the statement on which the error first appeared. The CFPB uses the same 60-calendar-day benchmark.
Notice what starts the clock. It is the statement, not the purchase. A charge you made in March may first show up on an April statement. The April statement date is what counts. When you first see a charge that looks wrong, check the statement date before anything else.
What the federal rules count as a billing error
Regulation Z uses "billing error" broadly. It includes charges you did not authorize, charges for the wrong amount, and charges for goods or services you never received. It also includes errors that are not fraud, such as getting the wrong merchandise or a quality problem.
The rule reaches beyond everyday purchases. It covers balance transfers, online and mobile payments, convenience checks, and ATM cash advances. It does not require you to send the notice to a named person or department. Still, sending it to the billing-dispute address on your statement is the practical route.
One more number to know. Your liability for unauthorized use is limited to $50. Defective-goods disputes may follow a different path, and the CFPB says so. The sources reviewed here do not lay out that separate process, so the type of problem matters.
How the issuer must respond
Once the issuer gets your written notice, its own deadlines begin. It must acknowledge the dispute within 30 days. It must resolve it within two billing cycles, and never later than 90 days. The CFPB adds that the company generally has 30 days to send a letter confirming receipt, unless it has already finished its investigation by then.
If the issuer agrees you were right, it must remove the charge from your bill. If it decides the bill was correct, it must explain why in writing. It must also say how much you owe and when payment is due.
What if you already paid? You can still dispute the charge. The money just may not come back until the company rules in your favor.
Card network and merchant chargeback timelines
A chargeback is a separate process. The card network and the merchant's payment processor run it, and it can reverse a payment. Industry commentary often cites 120 days from the transaction date, or the expected delivery date if that is later. That figure comes from merchant-side guidance. It is not a federal deadline.
The start date also shifts. Visa and Mastercard often count from the processing or delivery date. American Express generally counts from the statement posting date. Processors set their own, often tighter, response deadlines for merchants. Treating 120 days as one universal number oversimplifies things. Do not assume the network clock matches the 60-day federal one.
Practical steps and records that support a dispute
The CFPB suggests calling the card company right away. Then follow up with a written billing error notice. Describe the error and include your account details.
- Keep a copy of the notice and the statement.
- Save receipts and any messages with the merchant.
- Log the dates of your follow-up calls.
Your credit card agreement also spells out your rights on unauthorized charges and the issuer's own dispute steps. If you cannot find it, the CFPB's Credit Card Agreement Database is a public place to look. This is general education, not advice about any one account.
Gaps and limits of the current guidance
Some questions stay open. The sources reviewed here do not say what happens if you file after the 60 days end. They do not explain how to challenge an issuer's final decision beyond a CFPB complaint. They do not cover debit card disputes. They also do not give statement-date rules for every issuer.
So keep three things separate: the 60-day federal window, the issuer's response deadlines, and any network or merchant timeline. Each has its own start date. For a specific situation, start with your card agreement, the billing-rights notice from your issuer, and the regulators' published pages.
