Yes, you can dispute a charge, but the process and your protection depend on how you paid
A chargeback is a formal dispute you file with your bank to reverse a transaction. If you paid with a debit card, you have the right to dispute the charge within a set window—usually 60 days from when you first saw it on your statement. If you paid by check or ACH transfer, the process is different and often slower. Your bank cannot simply reverse the money on your say-so; they investigate whether the charge was unauthorized, fraudulent, or the merchant failed to deliver what you paid for.
The strength of your case matters. "I changed my mind" or "I didn't like the product" are not valid reasons for a chargeback. Valid reasons include: the merchant charged you twice for one purchase, charged you an amount different from what you agreed to, never delivered the goods or service, or you never authorized the charge at all. Your bank will ask you to explain which category applies and provide evidence—receipts, emails, screenshots of the agreement, proof of non-delivery.
Key Takeaways
- Debit card disputes must be filed within 60 days of the charge appearing on your statement; check and ACH disputes have different timelines and procedures.
- Valid chargeback reasons are unauthorized charges, duplicate charges, wrong amounts, or non-delivery—not buyer's remorse or dissatisfaction with quality.
- Your bank will investigate and may reverse the charge temporarily while they gather evidence from the merchant.
- The merchant can fight back with their own evidence, and if they do, your bank may reverse the reversal and put the money back in their account.
- Disputing a charge does not erase it from your record; it creates a dispute notation that both you and the merchant can see.
How to file a dispute with your bank
Contact your bank as soon as you notice the problem. Most banks let you start a dispute online through your checking account portal, by phone, or in person at a branch. You will need the transaction date, the merchant name, the amount, and a clear explanation of why the charge is wrong. Write down exactly what happened: "I was charged $89.99 on March 15 for a flight I never booked" or "The merchant charged me $150 but our invoice said $75."
Your bank will give you a dispute case number and a timeline—usually 10 business days for them to acknowledge receipt, then 30 to 45 days to investigate. During this time, they may provisionally credit your account (put the money back while they investigate) or ask you to wait. Some banks credit first and investigate second; others investigate first. Ask your bank which approach they use, because it affects whether you have access to the money while the dispute is open.
Keep copies of everything you send: your written dispute, receipts, emails with the merchant, screenshots, tracking numbers, anything that supports your version. If the merchant responds with their own evidence, your bank will share it with you and give you a chance to reply before making a final decision.
Debit card disputes versus check and ACH disputes
Debit card disputes are protected under federal law (Regulation E). You have 60 days from the date the charge appears on your statement to report it. Your bank must investigate within 10 business days and resolve it within 45 days. If they find in your favor, they must return the money. If they find against you, they must explain why in writing.
Check disputes work differently because checks are not electronic transactions. If someone forged your signature or cashed a check you never wrote, contact your bank immediately. They will investigate, but the timeline is longer and the process is more manual. You may need to file a police report for forgery. If the check cleared and the bank paid it, reversing it is harder and slower than reversing a debit card charge.
ACH transfers (direct deposits, bill payments, transfers between accounts) also fall outside Regulation E in some cases. If you authorized an ACH payment but the merchant charged the wrong amount or charged you twice, you can dispute it—but you have only 60 days, and your bank's investigation may take longer than a debit card dispute. If you did not authorize the ACH at all, report it immediately; unauthorized ACH disputes have stronger protections.
What happens if the merchant disputes your dispute
When you file a chargeback, the merchant gets notified and has the chance to respond. They can submit their own evidence: a signed receipt showing you agreed to the charge, delivery confirmation, emails where you approved the transaction, or a record showing you already received a refund. If their evidence is stronger than yours, your bank may side with them and reverse the provisional credit they gave you.
This is called a chargeback reversal. The money goes back out of your account and back to the merchant. You will be notified, and you have the right to respond one more time with additional evidence before your bank makes a final decision. If you have new proof—a receipt showing a different amount, a tracking number proving non-delivery, an email from the merchant admitting the error—submit it immediately.
If your bank rules against you after the second round, the dispute is closed and the charge stands. You cannot file the same dispute twice. Your only remaining option is to pursue the merchant through small claims court or a credit card chargeback (if you used a credit card instead of a debit card).
Timeline and what to expect at each stage
| Stage | Timeline | What Happens |
|---|---|---|
| You file the dispute | Day 1 | You contact your bank with the transaction details and reason. |
| Bank acknowledges | Within 10 business days | Bank confirms receipt and assigns a case number. May provisionally credit your account. |
| Bank investigates | 10 to 45 days | Bank requests evidence from you and the merchant, reviews both sides. |
| Merchant responds | Usually within 7 to 10 days of notification | Merchant submits their evidence and explanation. |
| Bank decides | By day 45 | Bank rules in your favor (charge reversed) or against you (charge stands). Notifies both parties in writing. |
| You can respond to merchant's evidence | Usually 7 to 10 days after receiving merchant's response | If you have new evidence, submit it. Bank may reopen investigation. |
| Final decision | By day 90 total | Bank makes final ruling. Dispute closes. No further appeals through the bank. |
When a chargeback might hurt you
Filing a chargeback does not damage your credit score directly—chargebacks do not appear on your credit report. However, if you file too many chargebacks in a short time, your bank may close your account or flag you as a high-risk customer. Some banks have policies: more than three chargebacks in 12 months can trigger account closure.
Merchants also track chargebacks. If you file a chargeback against a small business or online seller, they may add you to a chargeback database that other merchants can see. This can make it harder to do business with certain sellers in the future. Some merchants will refuse to sell to you again or require payment by wire transfer or cash only.
If you lose the dispute, you owe the full amount plus any fees your bank charges for the dispute process. Some banks charge $15 to $100 per chargeback filed, whether you win or lose. Check your account agreement to see what your bank charges.
What to do before filing a chargeback
Contact the merchant first. Many charges that look wrong are actually mistakes—a duplicate charge that will be refunded, a hold that will drop off, a charge in a different currency that looks larger than it is. Send an email or call and explain the problem. Ask for a refund or a correction. Keep the merchant's response in writing.
If the merchant refuses to help or does not respond within a few days, then file the dispute with your bank. Having proof that you tried to resolve it with the merchant first strengthens your case. Your bank will see that you gave the merchant a fair chance and will weigh that in your favor.
If the merchant is out of business or unreachable, file the dispute immediately. Do not wait for a response that will never come. Your bank understands that some merchants disappear, and they will investigate based on the evidence you provide.
Frequently Asked Questions
How long do I have to dispute a charge?
For debit card charges, you have 60 days from the date the charge appears on your statement. For checks and ACH transfers, the timeline varies by bank but is usually 60 days as well. After 60 days, most banks will not open a dispute. Contact your bank immediately if you spot a problem.
Will I get my money back while the dispute is being investigated?
It depends on your bank. Some banks provisionally credit your account within a few days of opening the dispute, so you have access to the money while they investigate. Others make you wait until the investigation is complete. Ask your bank which approach they use when you file the dispute.
What if I authorized the charge but the merchant delivered the wrong thing?
If you paid for a specific item and received something different, or if the merchant never delivered anything at all, that is a valid chargeback reason. You authorized the payment, but the merchant did not hold up their end of the deal. File the dispute and explain what you ordered versus what you received or did not receive.
Can the merchant sue me if I file a chargeback?
A chargeback is not a legal action, so the merchant cannot sue you directly for filing one. However, if you file a chargeback you know is false (you received the item and are lying about it), the merchant can pursue you for fraud or theft. Only file disputes for charges that are genuinely wrong or unauthorized.
What happens if my bank and the merchant keep disagreeing?
Your bank makes the final decision after investigating both sides. If they rule against you, the dispute closes and you cannot appeal through your bank. Your only option then is to pursue the merchant in small claims court if the amount is large enough to justify the cost and effort.
