Banks must return your money, but the timeline and your protection depend on what kind of transaction went wrong

If a bank holds your money by mistake, loses a deposit, or processes a transaction incorrectly, you have legal rights to get it back. The speed depends on whether the error is on the bank's side, whether you reported it quickly, and what type of account or transaction is involved. Federal law sets minimum protections, but the actual timeline can range from a few business days to several weeks.

The key is knowing which agency oversees your bank and what to do if the bank refuses to correct the error. Most banks are insured by the Federal Deposit Insurance Corporation (FDIC), which means your deposits up to $250,000 per account type are protected. But FDIC insurance covers bank failure, not everyday errors — for those, you need to file a dispute directly with the bank and escalate if necessary.

Key Takeaways

  • Banks must investigate errors within 10 business days if you report them in writing, and must refund you within one business day if the error is confirmed on their side.
  • If you report a missing deposit or unauthorized transaction by phone, the bank has 10 business days to investigate; if you report in writing, they must act faster for certain transaction types.
  • FDIC insurance protects deposits up to $250,000 per account type if the bank fails, but does not cover everyday errors — those require a dispute filed with the bank itself.
  • If your bank refuses to refund you after investigation, you can file a complaint with the FDIC, your state banking regulator, or the Consumer Financial Protection Bureau.
  • Debit card disputes have different timelines than ACH transfers or check deposits, so the type of transaction matters for how long the bank has to respond.

What the bank owes you when it makes an error

If the bank deposits money into the wrong account, fails to credit a deposit you made, or processes a withdrawal you did not authorize, the bank is responsible for fixing it. The bank's obligation depends on whether you catch the error quickly and how you report it.

Under the Electronic Funds Transfer Act (EFTA), if you report an error in writing within 60 days of the statement date, the bank must investigate and either correct the error or explain why the transaction was correct. If the error is on the bank's side — for example, they credited a deposit to someone else's account — they must refund you within one business day of confirming the mistake. If the error is on your side or the investigation is still ongoing, the bank must provisionally refund you within 10 business days while they finish investigating.

For debit card fraud or unauthorized transactions, the timeline is tighter. If you report the fraud within two business days, your liability is capped at $50. If you wait longer than two business days but report within 60 days, you could be liable for up to $500. After 60 days, you may lose all protection.

How to report an error and start the refund process

Contact your bank in writing as soon as you notice the error. A phone call starts the clock, but a written notice — email, letter, or through your online banking portal if the bank accepts disputes that way — creates a record the bank must respond to. Include your account number, the date of the transaction, the amount, and a clear description of what went wrong.

The bank must acknowledge receipt of your dispute within two business days and send you a written explanation of their investigation within 10 business days. If they need more time, they can extend the investigation to 45 days, but only if they provisionally refund you the disputed amount in the meantime. Once the investigation closes, they must send you a final written explanation and either confirm the refund or explain why the transaction was correct.

Keep copies of everything you send and every response the bank sends back. If the bank refuses to refund you and you believe they are wrong, you will need this documentation to file a complaint with a regulator. Document the date you reported the error, the method you used (email, certified mail, in-person), and the name of any bank employee you spoke with.

Different rules for different types of transactions

The law treats different kinds of transactions differently, which means the timeline for investigation and refund depends on what you are disputing. A debit card purchase follows different rules than an ACH transfer or a check deposit, even though they all go through your bank account.

Transaction TypeInvestigation TimelineRefund Timeline if Error ConfirmedYour Liability for Fraud
Debit card purchase or ATM withdrawal10 business days (can extend to 45)1 business day$50 if reported within 2 days; $500 if reported within 60 days
ACH transfer (direct deposit, bill pay)10 business days (can extend to 45)1 business daySame as debit card
Check deposit10 business days (can extend to 45)1 business dayNot applicable — check errors are handled differently
Wire transferVaries; not covered by EFTAVaries; depends on bank policyLimited protection; recovery depends on whether the receiving bank cooperates

Wire transfers are the exception. They are not covered by the EFTA, so the bank's obligation to recover your money depends on their own policy and the receiving bank's willingness to help. If you send money to the wrong account by wire, contact your bank immediately — they can ask the receiving bank to reverse it, but there is no legal requirement for them to do so, and recovery is not may provide. The sooner you report it, the better your chances, because the receiving bank is more likely to reverse a transfer before the recipient withdraws the funds.

What to do if the bank refuses to refund you

If the bank completes their investigation and denies your dispute, ask them in writing why they believe the transaction was correct. Request copies of any documentation they used to reach that conclusion. If you still disagree, you have the right to file a complaint with the regulator that oversees your bank.

Most banks are regulated by the Office of the Comptroller of the Currency (OCC) if they are national banks, or by your state's banking regulator if they are state-chartered. You can also file a complaint with the Consumer Financial Protection Bureau (CFPB), which handles consumer disputes across all banks. The CFPB complaint process is free and does not require a lawyer.

To file with the CFPB, go to consumerfinance.gov/complaint and select "Bank account or service" as the issue. Describe what happened, what the bank said, and what you want them to do. The CFPB forwards your complaint to the bank, and the bank has 15 days to respond. The CFPB then sends you a copy of their response and any supporting documents. Filing with the CFPB creates an official record and often prompts banks to reconsider disputes they initially denied.

FDIC insurance and what it covers

The FDIC insures deposits up to $250,000 per depositor, per bank, per account type. This means if your bank fails and closes, the FDIC will reimburse you up to $250,000. However, FDIC insurance does not cover everyday errors like a missing deposit or an unauthorized transaction — those are handled through the dispute process described above.

Different account types are insured separately. A checking account, savings account, and money market account at the same bank are each insured up to $250,000. If you have $200,000 in checking and $100,000 in savings at the same bank and the bank fails, you are fully covered. If you have $300,000 in checking, only $250,000 is insured, and you lose $50,000.

Joint accounts are insured separately as well. If you and your spouse have a joint checking account with $300,000, the FDIC insures up to $250,000 of that joint account. Each of you is also insured separately on your individual accounts at the same bank. You can check whether your bank is FDIC-insured by searching the FDIC's BankFind tool at fdic.gov.

How long refunds actually take in practice

The law sets a minimum timeline, but actual refunds often take longer. If the bank confirms the error is on their side, they must refund you within one business day. However, if the investigation extends to 10 or 45 days, you will not see the money until after that period closes and the bank processes the refund.

In practice, most straightforward errors — a deposit credited to the wrong account, a duplicate charge — are resolved within 5 to 10 business days. More complex cases, like fraud investigations or disputes involving multiple transactions, can take the full 45 days. Once the bank approves the refund, it typically appears in your account within 1 to 3 business days, depending on how the bank processes refunds.

If the bank provisionally refunds you while investigating, that money is in your account immediately, even if the investigation is still ongoing. If the investigation later determines the transaction was correct, the bank can reverse the provisional refund, but they must notify you in writing first and give you a chance to respond before taking the money back.

Frequently Asked Questions

What if I reported the error more than 60 days after my statement?

You lose the legal protection under the EFTA. The bank is no longer required to investigate or refund you. However, you can still contact the bank and ask them to review the transaction as a courtesy. Some banks will do so, but they are not legally obligated to. If the bank refuses, your only option is to file a complaint with the CFPB or your state regulator and explain why the delay occurred.

Can the bank charge me a fee while they investigate my dispute?

No. While the bank investigates, they cannot charge overdraft fees, late fees, or other charges related to the disputed amount. If they do, you can ask them to reverse those fees as part of your dispute. If they refuse, include the fee charges in your complaint to the CFPB.

What if the bank says I authorized the transaction, but I did not?

File a written dispute claiming fraud or unauthorized use. The bank must investigate and determine whether you actually authorized it. If you can show you did not have access to your card or account at the time, or if the transaction occurred in a different location than where you were, that strengthens your case. Keep any evidence — location data from your phone, receipts showing where you were, communications with the merchant.

Does the bank have to refund me if I sent money to the wrong account by mistake?

Not automatically. If you sent an ACH transfer or bill payment to the wrong account number, the bank can ask the receiving bank to reverse it, but they are not required to. Wire transfers have even less protection. Contact your bank immediately and ask them to attempt a reversal. If the receiving bank refuses or the money has already been withdrawn, recovery is unlikely without legal action against the recipient.

What if my bank is not FDIC-insured?

Most banks are FDIC-insured, but some credit unions are insured by the National Credit Union Administration (NCUA) instead. The coverage limits are the same — $250,000 per account type. If your bank is not insured by either agency, your deposits are not protected if the bank fails. You can check whether your bank is FDIC-insured by searching the FDIC's BankFind tool at fdic.gov.
