Most banks refund unauthorized transactions within 5 to 10 business days, but the full timeline depends on how quickly you report it and what type of transaction it was

When you report an unauthorized charge, your bank must provisionally credit your account within one business day if you reported it by phone, or by the end of the next business day if you reported it in writing or online. That provisional credit is not the final refund — it is your bank putting the money back while they investigate. The actual refund decision comes later.

The investigation itself takes up to 10 business days for most transactions, though your bank can extend that to 20 business days if they need more time to contact the merchant or verify details. Once they determine the charge was truly unauthorized, they issue the permanent refund. If you already received the provisional credit, you keep it. If you did not, the permanent refund becomes your money at that point.

Wire transfers and ACH payments (bank-to-bank transfers) follow different rules and often cannot be reversed at all, even if unauthorized. Those are covered separately because the timeline and your options are much narrower.

Key Takeaways

  • Report unauthorized charges as soon as you notice them — the faster you report, the faster your bank must act, and delays on your end can reduce your protection.
  • Your bank must put money back in your account within one business day of a phone report, but the investigation to confirm it was unauthorized takes up to 10 business days more.
  • Debit card fraud and credit card fraud have different timelines and different liability rules — credit cards are usually faster and your liability is capped at $50.
  • Wire transfers and ACH payments are nearly impossible to reverse, so if you sent money to a scammer via bank transfer, recovery is unlikely even if your bank investigates.

Debit card unauthorized charges: the 10-day investigation window

When you report an unauthorized debit card charge, your bank must credit your account provisionally within one business day. That money is yours to use while the bank investigates whether the charge was actually unauthorized. You are not waiting for the refund to use your account — you have the money back when ready for practical purposes.

The investigation takes up to 10 business days from the date you reported it. During that time, the bank contacts the merchant, reviews transaction details, and checks whether the charge matches your usual spending patterns or location. If the merchant cannot prove you authorized it, the bank makes the provisional credit permanent and closes the case. If the merchant provides evidence you did authorize it, the bank can reverse the provisional credit and you lose the money again.

Your liability for unauthorized debit card charges is capped at $50 if you report within two business days of discovering the fraud. If you wait longer than two business days but report within 60 days, your liability can go up to $500. After 60 days, you may have no protection at all, depending on your bank's policy and your state's laws.

Credit card unauthorized charges: faster and more protective

Credit card fraud is handled under the Fair Credit Billing Act, which gives you stronger protections than debit cards. Your liability is capped at $50 per card, period — there is no higher tier if you wait to report. You also do not lose access to your money while the bank investigates, because you are not spending your own funds; you are spending the card issuer's money.

When you report an unauthorized credit card charge, the card issuer must acknowledge your dispute within 30 days and investigate within 60 days. In practice, most card issuers reverse the charge within 5 to 10 business days and send you a written explanation later. You can use your card normally during the investigation — the disputed amount is straightforward not counted against your credit limit.

The card issuer does not need to put money back into your bank account because the charge never came out of your bank account in the first place. Instead, they remove the charge from your bill. If you already paid that bill, they issue a credit to your account or refund the amount to your original payment method.

Wire transfers and ACH payments: almost no reversal option

If you sent money via wire transfer or ACH (Automated Clearing House) payment to a scammer, the timeline for recovery is not measured in days — it is measured in whether recovery is possible at all. Wire transfers cannot be recalled once they leave your bank. ACH payments can sometimes be reversed, but only within a narrow window and only if the receiving bank cooperates.

For wire transfers, your bank can attempt to contact the receiving bank and ask them to freeze the funds, but they have no legal obligation to do so. If the receiving bank is in another country or the scammer has already moved the money, recovery is essentially impossible. The entire process takes days or weeks, and the outcome is usually that the money is gone.

For ACH payments, you have up to 180 days to report the fraud, but your bank can only reverse the payment if the receiving bank has not yet settled it — usually within one to two business days. After settlement, reversal requires the receiving bank's consent, which a scammer's bank account will not receive. If you discover the fraud quickly, report it when ready to your bank and ask them to attempt a reversal, but do not expect success.

What slows down your refund

The most common delay is reporting the fraud late. If you do not report an unauthorized charge within 60 days of your statement date, your bank may deny your claim entirely. Even if they investigate, a late report weakens your case because the merchant has had time to provide evidence of authorization, and the transaction is harder to reverse.

A second delay happens when the merchant disputes the chargeback. If you report a charge as unauthorized and your bank initiates a dispute with the merchant, the merchant can provide evidence that you authorized it — a signed receipt, an IP address match, a phone number match, or a delivery confirmation. If the evidence is strong, your bank sides with the merchant and you lose the dispute. This process adds 30 to 60 days to the timeline.

International transactions also slow things down. If the unauthorized charge came from a merchant in another country, your bank must contact a foreign bank to investigate, which can add 10 to 20 business days to the standard timeline. Currency conversion issues and different fraud standards in other countries make these cases harder to resolve.

What to do while you wait for your refund

Once you report an unauthorized charge, document everything. Keep the date and time you reported it, the name of the bank representative you spoke to, and any confirmation number they gave you. Request written confirmation of your dispute in writing or through your online banking portal — do not rely on a phone call alone.

Check your account daily to confirm the provisional credit appeared. If it did not show up within one business day of your report, call your bank again and ask why. A missing provisional credit is a sign something went wrong with your report or your bank did not process it correctly.

Do not close the account or card while the dispute is open. Your bank needs to be able to contact you and may need to reverse the provisional credit if they determine the charge was authorized. Closing the account can complicate the investigation and delay your refund.

If the unauthorized charge is part of a larger fraud pattern — multiple charges, identity theft, or a compromised card — report it to the Federal Trade Commission at IdentityTheft.gov. This creates an official record and may help you if your bank denies your dispute or if you need to dispute the charge with credit bureaus.

When your bank denies your dispute

If your bank investigates and concludes the charge was authorized, they will deny your dispute and reverse any provisional credit they gave you. This happens when the merchant provides evidence — a signature, a PIN entry, a matching IP address, or a delivery confirmation — that suggests you made the purchase.

You have the right to appeal a denied dispute. Ask your bank in writing for the evidence the merchant provided and explain why you believe it is incorrect. If the merchant's evidence is weak or does not match your account, your bank may reverse their decision. This appeal process takes another 30 to 60 days.

If your bank continues to deny the dispute after appeal, your last option is to file a complaint with your bank's regulator. For national banks, that is the Office of the Comptroller of the Currency. For state banks, it is your state's banking regulator. For credit unions, it is the National Credit Union Administration. These complaints do not may provide a refund, but they create pressure on your bank to reconsider.

Frequently Asked Questions

Do I have to wait 10 days to get my money back?

No. Your bank must put the money back within one business day if you reported by phone. The 10-day window is for the investigation, not for getting your provisional credit. You can use the money when ready after the provisional credit posts.

What if the unauthorized charge is from a merchant I recognize but I did not make the purchase?

Report it as unauthorized anyway. A familiar merchant name does not mean you authorized the charge — your card could have been compromised, or someone else could have used your card number. Your bank will investigate and contact the merchant to verify whether you made the purchase.

Can my bank take back the provisional credit if they decide the charge was authorized?

Yes. If the investigation concludes you authorized the charge, your bank reverses the provisional credit and you lose the money again. This is why documenting your dispute and keeping records is important — if you believe the decision is wrong, you can appeal.

How long does it take to get a refund for a fraudulent wire transfer?

Wire transfers cannot be reversed once they leave your bank. Your bank can contact the receiving bank and ask them to freeze the funds, but this rarely succeeds and takes days or weeks. If the receiving bank is uncooperative or the money has already moved, recovery is unlikely.

What happens if I report the fraud after 60 days?

Your bank may deny your claim entirely, depending on their policy and your state's laws. Even if they investigate, a late report weakens your case because the merchant has had time to provide evidence of authorization. Report unauthorized charges as soon as you discover them.
