What a chargeback is and when your bank will file one
A chargeback is a formal dispute you file with your bank or credit card company to reverse a transaction. Your bank contacts the merchant's bank, demands proof that the charge was legitimate, and if the merchant cannot provide it, the money comes back to you. The process exists because merchants have more power over the transaction than you do — they control the equipment, the receipt, and the record — so chargebacks are the tool that balances that imbalance.
You can file a chargeback for two broad reasons: the transaction was unauthorized (someone else used your card), or the transaction was authorized but the merchant failed to deliver what they promised, charged you twice, or charged you the wrong amount. The merchant's bank then has a window — usually 7 to 10 days — to respond with evidence that the charge was valid. If they do not respond or their evidence is weak, your bank returns the money and closes the case in your favor.
Chargebacks are not the same as a refund request. When you ask a merchant directly for a refund, they decide whether to give it. When you file a chargeback, you are asking your bank to investigate and decide. This matters because merchants often ignore refund requests, but they cannot ignore a chargeback — their bank forces them to respond.
Key Takeaways
- A chargeback is a dispute filed through your bank that reverses a transaction by forcing the merchant's bank to prove the charge was valid.
- You can file a chargeback for unauthorized charges or for authorized charges where the merchant failed to deliver, double-charged, or charged the wrong amount.
- The merchant's bank has 7 to 10 days to respond with evidence; if they do not or their evidence is weak, your money is returned.
- Chargebacks take 30 to 90 days from start to finish, and you should contact your merchant first because many disputes resolve faster that way.
- Filing too many chargebacks can cause your bank to close your account, and merchants can sue you if they believe you filed a chargeback in bad faith.
How to file a chargeback with your bank
Contact your bank or credit card company as soon as you notice the unauthorized or incorrect charge. Most banks have a dispute phone line, a web portal, or a mobile app where you can report the transaction. You will need the transaction date, the merchant name, the amount, and a clear explanation of why the charge is wrong. Write down the date and time you called, and the name of the person who took your report — you may need this later.
Your bank will open a dispute case and assign it a reference number. They will send you a temporary credit (usually within 10 business days) while they investigate, though this is not final — if the merchant provides strong evidence that the charge was valid, your bank can take the credit back. Do not assume the temporary credit means you have won the dispute.
The bank will then contact the merchant's bank and request documentation: the signed receipt, proof of delivery, email confirmations, or any other evidence that shows you authorized the charge and received what you paid for. The merchant's bank forwards this to the merchant, who has a deadline to respond. If the merchant ignores the request or submits weak evidence, your bank will rule in your favor and make the temporary credit permanent.
Timeline: how long a chargeback takes
The chargeback process moves in stages, and the total time varies by bank and by card network (Visa, Mastercard, American Express, Discover). Here is what to expect:
| Stage | Typical Timeline | What Happens |
|---|---|---|
| You file the dispute | Day 1 | You contact your bank and report the transaction. |
| Bank opens case | Days 1–3 | Your bank creates a dispute file and sends it to the merchant's bank. |
| Temporary credit issued | Days 3–10 | Your bank credits your account while investigating. This money may be taken back. |
| Merchant responds | Days 7–30 | The merchant's bank collects evidence and submits it to your bank. |
| Bank makes decision | Days 30–60 | Your bank reviews the evidence and rules in your favor or the merchant's favor. |
| Case closes | Days 60–90 | The final decision is sent to both banks. If you won, the credit becomes permanent. |
If the merchant disagrees with your bank's decision, they can file a counter-dispute and submit additional evidence. This extends the timeline by another 30 to 60 days. In rare cases, the dispute goes to the card network (Visa or Mastercard) for final arbitration, which can take several more weeks.
During this time, keep records of everything: your dispute reference number, copies of emails with the merchant, screenshots of the transaction, and any communication about the product or service. If the merchant contacts you directly to settle, respond in writing and keep those messages — they may help your case.
Unauthorized charges versus merchant disputes
The reason for your chargeback affects how your bank investigates and how quickly they rule. Unauthorized charges — where someone else used your card without permission — are usually the fastest to resolve. Your bank will ask the merchant whether they have a signed receipt or a delivery confirmation to your address. If the charge went to a different address or the merchant has no proof of delivery, your bank will rule in your favor within 30 to 45 days. Fraud protection laws require banks to reverse unauthorized charges quickly, so this category gets priority.
Merchant disputes — where you authorized the charge but the merchant failed to deliver, charged you twice, or charged the wrong amount — take longer because your bank has to evaluate whether the merchant actually breached the agreement. If you ordered a laptop and it never arrived, your bank will ask the merchant for a tracking number or delivery confirmation. If the merchant provides proof of delivery, your bank may rule against you even if you claim you never received it. If the merchant has no proof, you win. These disputes often hinge on what you can prove, so documentation matters more.
If you ordered something online and the merchant charged your card but never shipped it, that is a merchant dispute, not fraud. Your bank will investigate, but the outcome depends on whether the merchant can show they attempted delivery or whether you signed for the package.
What happens to the merchant when you file a chargeback
When your bank files a chargeback, the merchant's bank notifies the merchant and deducts the amount from their account. The merchant then has to decide whether to fight it by submitting evidence or accept the loss. If the merchant fights and loses, they pay a chargeback fee (usually $15 to $100) on top of refunding the transaction amount. If they do not respond at all, they lose the money and still pay the fee.
Merchants track chargebacks, and if a business receives too many in a short period, their bank may flag them as high-risk. This can result in higher processing fees, reserve requirements (the bank holds a percentage of their revenue), or account termination. Some merchants have chargeback rates above 1 percent and lose their ability to accept cards entirely.
This is why merchants often prefer to refund you directly — it costs them less than fighting a chargeback. If you contact a merchant and explain the problem before filing a chargeback, many will refund you immediately to avoid the chargeback process. This is also faster for you: a direct refund can take 3 to 5 business days, while a chargeback takes 60 to 90 days.
Risks of filing chargebacks
Filing chargebacks has consequences if you abuse the process. Banks track how many chargebacks you file, and if you file too many in a short period, your bank may close your account. The threshold varies by bank, but filing more than one chargeback per month or three in a year can trigger a review. If your bank believes you are filing chargebacks in bad faith — disputing legitimate charges to get free products — they can terminate your account and report you to ChexSystems, a banking blacklist that makes it hard to open accounts elsewhere.
Merchants can also sue you if they believe you filed a chargeback dishonestly. If you received a product, used it, and then filed a chargeback claiming you never received it, the merchant can take you to small claims court. You would have to prove your claim, and if the merchant has delivery confirmation or a signed receipt, you will lose and may owe court costs.
File a chargeback only when the charge is genuinely unauthorized or the merchant genuinely failed to deliver. Do not use chargebacks as a way to get a refund when the merchant is simply unresponsive — contact them first, give them a reasonable time to respond, and escalate to your bank only if they ignore you.
Chargebacks versus other dispute options
Before filing a chargeback, consider whether another option might be faster or more appropriate. If the merchant is simply slow to respond, a direct request for a refund takes 3 to 5 business days. If the merchant is unresponsive, filing a complaint with your state's attorney general or the Federal Trade Commission (FTC) can pressure them to respond, though this does not reverse the charge directly. If you used a third-party payment service like PayPal or Stripe, those platforms have their own dispute resolution process that is often faster than a bank chargeback.
For credit cards, chargebacks are your strongest tool because card networks have rules requiring merchants to respond. For debit cards, chargebacks are slower and merchants have more time to respond. For ACH transfers or wire transfers, chargebacks do not exist — your only option is to contact your bank and ask them to reverse the transaction, which only works if the receiving bank agrees. For checks, you can stop payment or file a fraud claim, but the process is different from a chargeback.
If you are disputing a recurring charge (a subscription you canceled but kept being billed), some banks allow you to dispute the charge directly without going through the full chargeback process. Ask your bank whether they offer a "billing dispute" or "recurring charge dispute" option, which is faster than a formal chargeback.
Frequently Asked Questions
Can I file a chargeback if I changed my mind about a purchase?
No. Chargebacks are for unauthorized charges or merchant failures, not buyer's remorse. If you bought something and then decided you did not want it, you need to contact the merchant and ask for a refund under their return policy. Filing a chargeback for a purchase you simply regret is considered chargeback fraud and can result in your bank closing your account.
What if the merchant claims they shipped the item but I never received it?
File a chargeback and tell your bank that the package never arrived. Your bank will ask the merchant for tracking information and delivery confirmation. If the merchant has a tracking number showing delivery to your address, your bank may rule against you even if you did not receive it — in that case, you would need to file a claim with the shipping carrier instead. If the merchant has no tracking number, your bank will likely rule in your favor.
How many chargebacks can I file before my bank closes my account?
There is no fixed number, but most banks become concerned after three to five chargebacks in a year. The threshold depends on your bank and your account history. If you have been a customer for years with no disputes, one or two chargebacks will not trigger action. If you file multiple chargebacks in a short period, your bank may review your account and close it if they believe you are disputing legitimate charges.
Can I file a chargeback after the merchant already refunded me?
No. If the merchant refunded you, the charge is already reversed and there is nothing to dispute. Filing a chargeback after receiving a refund is fraud and can result in criminal charges. Wait for the refund to post to your account before closing the dispute.
What if my bank rules against me in the chargeback?
If your bank decides the merchant's evidence is stronger than yours, they will remove the temporary credit from your account and close the case. You can ask your bank to review the decision, but they rarely overturn it. Your only other option is to contact the merchant directly and try to negotiate a refund, or to file a complaint with your state's attorney general if you believe the merchant committed fraud.
