The window to reverse an ACH payment depends on whether you initiated it or received it
If you sent an ACH payment by mistake, you have until the end of the business day the payment is scheduled to move—usually one business day after you authorized it. After that point, the payment has left your bank and entered the ACH network, and you cannot simply cancel it. Instead, you must file a reversal request (also called a debit reversal or return), which asks the receiving bank to send the money back. This process takes three to five business days and is not may provide to succeed.
If you received an ACH payment by mistake—someone sent you money they didn't mean to—you have no legal time limit to return it, but the sender's bank can file a reversal request up to two years after the transaction. The sooner you act, the easier the reversal becomes.
Key Takeaways
- You can cancel an ACH payment only before it settles, which is usually the same business day you sent it or the next day depending on your bank's cutoff time.
- Once an ACH payment settles, you must file a reversal request through your bank, which takes three to five business days and may not succeed if the recipient has already spent the money.
- The receiving bank has ten business days to investigate a reversal request and decide whether to return the funds.
- If you received money by mistake, the sender's bank can initiate a reversal up to two years later, so you should not spend it.
Canceling an ACH payment before it settles
Most banks allow you to cancel an ACH payment up until a specific cutoff time on the day you schedule it—often 2 p.m. or 5 p.m. Eastern time, though this varies by bank. If you miss that window, the payment moves into the ACH network overnight and cannot be stopped. Some banks let you cancel payments scheduled for future dates up until the day before they are set to process.
Contact your bank immediately if you need to cancel. Call the number on the back of your debit card or log into your online banking portal and look for a "pending transactions" or "scheduled payments" section. Many banks allow you to cancel directly through the app or website, but calling ensures someone confirms the cancellation in real time. Ask for a confirmation number.
Filing a reversal request after the payment settles
Once an ACH payment has settled—meaning it has moved out of your bank and into the receiving bank—you cannot cancel it directly. Instead, you file a reversal request with your bank. This is a formal request asking the receiving bank to return the funds. Your bank will initiate the request on your behalf, but the receiving bank makes the final decision.
The receiving bank has ten business days to investigate and respond. If the recipient still has the money in their account, the bank will usually return it. If the money has been spent or transferred elsewhere, the receiving bank may deny the reversal. In that case, you may need to pursue the matter through small claims court or contact the recipient directly to ask them to send the money back.
File your reversal request as soon as you realize the mistake. The longer you wait, the more likely the recipient has spent the money and the harder it becomes to recover.
Different rules for ACH reversals versus ACH returns
An ACH return is different from a reversal. A return happens when the receiving bank rejects the payment for a specific reason—the account number is wrong, the account is closed, or the recipient's bank flags it as fraudulent. Returns are automatic and happen within one to two business days. You do not need to file anything; your bank handles it.
A reversal is what you file when the payment went through successfully but you want it back. Reversals take longer because the receiving bank must investigate whether the recipient still has the funds. If the receiving bank cannot locate the money or the recipient disputes the reversal, the process can stretch to fifteen business days or longer.
What happens if the recipient disputes the reversal
The recipient can contest your reversal request. If they claim they were supposed to receive the money, the receiving bank will ask you to provide proof that the payment was unauthorized or sent by mistake. This might mean providing a written statement, screenshots of your banking records, or documentation showing the payment was a duplicate.
If the receiving bank sides with the recipient, the reversal is denied and the money stays with them. You then have the option to pursue the matter through your bank's dispute process, file a complaint with the Consumer Financial Protection Bureau, or take legal action if the amount is large enough to justify it.
ACH reversals for fraudulent or unauthorized payments
If someone else sent an ACH payment from your account without your permission, the rules are stricter in your favor. You have 60 days from the date the fraudulent transaction appears on your statement to report it to your bank. Your bank must then investigate and, if they confirm fraud, return the money within one to three business days in most cases.
Report fraud immediately by calling your bank or filing a dispute through your online banking portal. Do not wait. The 60-day window is firm, and after that your bank has no obligation to refund you. Provide your bank with as much detail as possible: when you first noticed the transaction, whether you recognize the recipient, and any steps you took to secure your account.
What to do if you received money by mistake
If an ACH payment landed in your account that you did not expect and do not recognize, do not spend it. The sender's bank can file a reversal request up to two years after the transaction. If you have already spent the money, you will owe it back and may face overdraft fees or a negative balance.
Contact your bank and let them know the payment was sent to you by mistake. Ask whether the sender has already filed a reversal request. If not, you can also try to contact the sender directly (if you can identify them from the transaction details) and ask them to file the reversal themselves, which is faster than waiting for their bank to initiate it.
Some banks allow you to voluntarily return the funds by initiating an ACH transfer back to the sender's account. This is the cleanest solution and protects you from disputes later.
Frequently Asked Questions
Can I reverse an ACH payment the same day I send it?
Only if you cancel it before your bank's cutoff time, usually 2 p.m. or 5 p.m. Eastern time. After that, the payment enters the ACH network overnight and cannot be canceled. You would then need to file a reversal request, which takes three to five business days.
What if the receiving bank says they cannot find the money?
If the recipient transferred the money to another account or spent it, the receiving bank may not be able to recover it. Your bank can file a second reversal request or escalate the matter, but if the money is truly gone, you may need to pursue the recipient directly or through small claims court.
Do I have to pay a fee to reverse an ACH payment?
Most banks do not charge a fee for filing a reversal request if the payment was sent by mistake. However, if you file multiple reversals or if the reversal is denied, some banks may charge a fee. Check your bank's fee schedule or ask when you file the request.
How do I know if my reversal request was successful?
Your bank will send you a notice once the receiving bank responds, usually within ten business days. You can also call your bank or check your online banking portal to see the status. The money should reappear in your account within one to three business days after approval.
What if I sent an ACH payment to the wrong person but the right account number?
This is treated as a reversal, not a return. The receiving bank will investigate, but if the account holder claims the payment was authorized, the reversal may be denied. File the request anyway and provide documentation showing the payment was sent to the wrong recipient. You may also need to contact the recipient directly and ask them to return the money voluntarily.
