How to Dispute a Charge on Your Credit Card: Step-by-Step Guide (2026)

Disputing a charge on your credit card is not just complaining -- it is exercising a legal right protected by federal law. The Fair Credit Billing Act (FCBA) gives every credit card holder the power to challenge unauthorized, incorrect, or fraudulent charges and requires card issuers to investigate them properly. In many cases, the disputed amount cannot even be reported as delinquent while the investigation is pending.

This step-by-step guide covers everything you need to know: when you can dispute, how to do it, critical deadlines, and what to do if your dispute is denied.

What Charges Can You Dispute?

Under the FCBA (15 U.S.C. Section 1666), you can dispute any of the following billing errors:

• Unauthorized charges -- charges you did not make or approve, including fraud
• Charges for goods or services not received -- you paid but the product was never delivered
• Charges for the wrong amount -- you were billed more than the agreed price
• Duplicate charges -- the same transaction posted twice
• Charges where the merchant failed to post a credit -- you returned an item but the refund never appeared
• Charges for which you need clarification -- you do not recognize the merchant name or transaction
• Math errors on your statement -- the statement total does not add up

The Critical 60-Day Deadline

The FCBA requires you to send your written dispute within 60 days of the date the first statement containing the error was mailed to you. This is not 60 days from the charge date -- it is 60 days from when the statement was sent.

If you miss this deadline, you lose your FCBA protections for that specific charge. The card issuer may still investigate as a courtesy, but they are not legally obligated to. That is why acting quickly is essential.

Important: For unauthorized charges due to fraud or a lost/stolen card, your liability is capped at $50 under the FCBA, and most major issuers offer $0 liability policies.

Step-by-Step: How to Dispute a Credit Card Charge

Step 1: Gather Your Documentation

Before you do anything else, collect the evidence that supports your dispute:

• A copy of your credit card statement showing the charge
• Any receipts, confirmation emails, or order numbers related to the transaction
• Screenshots of cancellation confirmations, chat logs, or email correspondence with the merchant
• Photos of damaged or incorrect goods, if applicable
• Notes about phone calls (date, time, representative name, what was said)

Step 2: Contact the Merchant First (Optional but Recommended)

In many cases, contacting the merchant directly is the fastest path to a refund. Many merchants will issue a credit without a formal dispute process. However, this is not required by law, and you should not delay your formal dispute if the merchant is unresponsive.

If you do contact the merchant, document the interaction and set a deadline. If they do not resolve it within 7-10 business days, move to the formal dispute process.

Step 3: Write Your Dispute Letter

The FCBA specifically requires a written notice sent to the card issuer's billing inquiries address. Your letter should include:

• Your name and account number
• The dollar amount of the disputed charge
• The date the charge appeared on your statement
• A clear explanation of why you believe the charge is an error
• Copies (not originals) of supporting documentation

Send the letter via certified mail with return receipt requested. This creates a legal record proving the date the issuer received your dispute, which starts the clock on their response obligations.

Step 4: File with Your Card Issuer Online (In Addition to the Letter)

Most card issuers also allow you to file disputes online or by phone. Do this in addition to your written letter, not instead of it. The online dispute process is faster for getting a provisional credit, but the written letter is what triggers your full FCBA protections.

When filing online, look for terms like "dispute a charge," "report a problem," or "billing error" on your issuer's website or app.

Step 5: Monitor the Investigation

After filing your dispute:

• The issuer must acknowledge your dispute within 30 days
• They must resolve the investigation within two billing cycles (no more than 90 days)
• During the investigation, the issuer cannot report the disputed amount as delinquent to credit bureaus
• Many issuers will issue a provisional credit while they investigate -- this temporarily reverses the charge on your account

What to Do If Your Dispute Is Denied

If the card issuer denies your dispute, they must send you a written explanation within the same timeframe. You then have several options:

1. Request the evidence they used -- you have the right to see what documentation the issuer relied on
2. Write a follow-up letter -- address the specific reasons for denial and provide additional evidence
3. File a complaint with the CFPB -- consumerfinance.gov/complaint -- companies respond to over 97% of CFPB complaints
4. File a complaint with your state attorney general -- many state AG offices have dedicated consumer protection units
5. Consider small claims court -- for disputes under your state's limit (typically $5,000-$10,000), small claims court is an affordable option

Credit Card Disputes vs. Debit Card Disputes

It is critical to understand that debit card disputes are governed by a different law: the Electronic Fund Transfer Act (EFTA, 15 U.S.C. Section 1693). The protections are weaker:

• You must report unauthorized debit card transactions within 2 business days to limit your liability to $50
• After 2 days but within 60 days, your liability increases to $500
• After 60 days, you may be liable for the entire amount
• Unlike credit cards, the money leaves your bank account immediately, and you may not get a provisional credit as quickly

This is one reason consumer advocates generally recommend using credit cards instead of debit cards for purchases -- the FCBA provides significantly stronger consumer protections.

Common Mistakes That Weaken Your Dispute

• Only disputing by phone -- phone disputes do not trigger your FCBA protections
• Missing the 60-day deadline -- once this window closes, your legal leverage is significantly reduced
• Sending to the wrong address -- the letter must go to the billing inquiries address, not the payment address
• Not keeping copies -- if you cannot prove you sent the letter, the issuer can claim they never received it
• Paying the disputed charge -- you are not required to pay the disputed portion while the investigation is pending
• Being too vague -- "I don't recognize this charge" is weaker than "I canceled this subscription on March 1 and was charged again on March 15 despite receiving confirmation number 12345"
