An ACH transfer from one bank to another moves money electronically between accounts through the Automated Clearing House network, and most transfers settle in one to three business days. To send one, you link the receiving account inside your bank’s website or app using its routing and account numbers, verify that you control it, then submit the amount. Setup is straightforward once you know what information to gather, how long processing takes, and what rights you have if something goes wrong.
What You Need Before You Start
Every ACH transfer requires a short list of details about the destination account:
- The nine-digit routing number of the receiving bank, found on the bottom left of a paper check or in the account details section of most banking apps.
- The account number.
- Whether the account is checking or savings.
- The account holder’s name as it appears on the account.
Getting even one digit wrong on the account or routing number can send money to the wrong place or cause the transfer to bounce. Banks don’t always verify that the name you enter matches the account number you provide, so the numbers matter more than the name. Double-check everything before you hit send.
How to Link the External Account and Send the Money
Most banks let you set up ACH transfers through their website or mobile app. Look for an option labeled something like “Transfer to External Account,” “Link an Account,” or “Send Money.” Enter the routing number, account number, and account type for the destination.
Before your first transfer to a new account, the bank usually makes you verify ownership. The common method is micro-deposits: your bank sends two tiny deposits, usually under ten cents each, to the external account over one to two business days. You log into the receiving bank, note the exact amounts, and type them back into the sending bank’s verification screen. That confirms you actually control both accounts. Some banks skip micro-deposits and use instant verification by letting you log into the other bank directly through a linking service.
Once the account is verified, pick the amount, confirm the details, and submit. The bank generates a confirmation number. Save it. If anything goes wrong during processing, that number is your proof of what you submitted and when.
How Long an ACH Transfer Takes
ACH transfers don’t move instantly. Banks collect transfer requests throughout the day and send them to the clearing house in batches. Standard transfers settle in one to three business days depending on the banks involved and when you submit.
The ACH network doesn’t process on weekends or federal holidays. A transfer you start Friday evening won’t begin processing until Monday, and if Monday is a holiday it slides to Tuesday. Plan ahead around long weekends if timing matters for rent, a closing, or a bill.
Same Day ACH
For faster delivery, many banks offer Same Day ACH. The network runs three processing windows each business day, with submission deadlines of 10:30 a.m., 2:45 p.m., and 4:45 p.m. Eastern Time.1Federal Reserve Financial Services. FedACH Processing Schedule Your bank’s internal cutoff is usually earlier than the network deadline, so check before you count on same-day settlement. Same Day ACH handles individual payments up to $1 million.2Nacha. ACH Payments Fact Sheet
Fees and Transfer Limits
Standard ACH transfers are free at most major banks, including Chase, Bank of America, Wells Fargo, Capital One, and Ally. If your bank does charge for standard external transfers, the fee is typically around $3, though calling customer service or visiting a branch instead of using the online portal sometimes triggers a higher fee. Same-day processing may carry a small fee of roughly $1 to $10 per transfer where banks charge for it.
Your bank sets its own daily and monthly caps on how much you can move through ACH. These vary widely based on account type, your history with the bank, and whether you’re sending or receiving. Daily outbound limits for personal accounts commonly fall between $2,500 and $25,000, with higher ceilings available for established customers and business accounts. These caps are bank policy, not federal rules. If you need to move more than your limit allows, call your bank. Some will raise the cap temporarily for a down payment or similar large transfer; others will suggest a wire, which usually has a higher per-transaction ceiling but costs $15 to $30.
Canceling or Stopping a Transfer
Whether you can call back a transfer depends on timing and on whether it’s a one-time payment you sent or a recurring charge you authorized.
For a one-time ACH transfer you initiated, if the transfer still shows “pending” in your bank’s system, you can usually cancel it online or by phone. Once the batch has been released to the clearing house, cancellation becomes much harder. At that point your bank would have to request a reversal from the receiving bank, which is not guaranteed to succeed.
For a recurring ACH debit, the law is more clearly on your side. Under Regulation E, you can stop any preauthorized recurring electronic payment by notifying your bank at least three business days before the next scheduled withdrawal. You can give notice by phone, online, or in writing. If you call it in, the bank can require written confirmation within 14 days, and the oral stop-payment order expires if you don’t follow up in writing when asked.3Consumer Financial Protection Bureau. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E) – Section 1005.10 Also contact the company charging you and revoke your authorization directly. Doing both creates a stronger paper trail if the charges continue.4Consumer Financial Protection Bureau. How Can I Stop a Payday Lender From Electronically Taking Money Out of My Bank or Credit Union Account Banks commonly charge a stop-payment fee, so ask about the cost when you place the order.
If You Send Money to the Wrong Account
Entering incorrect account details usually plays out one of two ways. Most often the transfer bounces back because the account number doesn’t exist or doesn’t match the routing number. That generally resolves within a few business days, though your bank may charge a returned-item fee.
The worse outcome is that the money lands in a real stranger’s account. Recovery is difficult, because ACH processing doesn’t always verify that the account holder’s name matches what you entered. Your bank can request a reversal, but the receiving bank isn’t obligated to pull money from another customer’s account without that customer’s cooperation. The originator has five business days from settlement to detect the error and must notify their bank within 24 hours of discovering it. After that window, recovery typically requires legal action. Getting the numbers right before you send is the only reliable safeguard.
If Someone Takes Money You Didn’t Authorize
Federal law caps your liability for unauthorized ACH debits based on how fast you report. Under Regulation E:
- Notify your bank within two business days of learning about the unauthorized transfer, and your maximum liability is $50.
- Report after two business days but within 60 days of receiving the bank statement showing the charge, and your exposure rises to $500.
- Miss the 60-day window, and you can be liable for the full amount of any unauthorized transfers that happen after that deadline.5Consumer Financial Protection Bureau. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E) – Section 1005.6
Separately, under Nacha’s rules the receiving bank can return an unauthorized consumer ACH debit within 60 calendar days of its settlement date.6Nacha. Differentiating Unauthorized Return Reasons Check your statements regularly. The sooner you spot a bad charge, the less exposure you face and the easier recovery becomes.
Transfers Out of Savings Accounts
Before 2020, federal rules under Regulation D limited savings accounts to six “convenient” transfers per month, which included ACH transfers to external accounts. The Federal Reserve removed that limit in April 2020,7Federal Reserve Board. Federal Reserve Board Announces Interim Final Rule to Delete the Six-Per-Month Limit on Convenient Transfers From the Savings Deposit Definition in Regulation D and the change is permanent.8Federal Register. Regulation D – Reserve Requirements of Depository Institutions Some banks still enforce their own monthly caps on savings transfers as a matter of internal policy. If you get hit with a fee for frequent ACH transfers out of savings, that’s a bank rule, not a federal one. Check your account agreement.
What ACH Transfers Don’t Trigger
Moving money between your own accounts at different banks is not a taxable event. You haven’t earned income; you’ve relocated funds you already own.
The $10,000 reporting threshold you may have heard about applies to physical currency transactions, not electronic transfers. Banks file a Currency Transaction Report with FinCEN when a customer deposits, withdraws, or exchanges more than $10,000 in actual paper bills and coins.9Federal Deposit Insurance Corporation. Currency Transaction Reporting An ACH transfer is electronic, so it doesn’t trigger that particular report. Banks do monitor accounts for suspicious activity under anti-money laundering rules, but a routine ACH transfer between your own accounts won’t raise flags.
