What Is an ACH Push and How Does It Work?

An ACH push is an electronic transfer you authorize from your own bank account to send money to someone else’s account. You tell your bank the amount, the recipient, and the destination account; your bank then routes the payment through the ACH Network, a nationwide batch-processing system governed by Nacha. Because you start the transfer yourself, nothing leaves your account unless you say so, and the recipient’s side has no ability to pull the funds on its own.

How the Money Moves

An ACH push is a “credit” transaction, meaning money flows outward from you to the recipient. You are the originator. Your bank, called the Originating Depository Financial Institution (ODFI), packages your instructions into a digital file and sends it through one of two ACH operators: the Federal Reserve’s FedACH or The Clearing House’s Electronic Payments Network.1Nacha. ACH Payments Fact Sheet The operator sorts the file and hands it off to the recipient’s bank, the Receiving Depository Financial Institution (RDFI), which credits the funds to the destination account.

The important thing to understand is who starts the transfer. With a push, you send money out. With a pull, someone else, such as a utility company or mortgage servicer, requests money from your account under an authorization you gave them earlier. A push requires your direct authorization each time, so your bank only moves the funds when you tell it to.2Nacha. New Nacha Rules Take Aim at Credit-Push Fraud

What ACH Pushes Are Used For

You already use ACH pushes, probably more often than you realize. A direct-deposited paycheck is an ACH push from your employer’s bank to yours. So are these:

  • Payroll and gig-worker payouts sent from an employer or platform to a worker’s account.
  • Tax refunds deposited by the IRS or a state tax agency into the account you listed on your return.
  • Recurring government benefits, such as Social Security and veterans’ benefits.
  • Vendor and supplier payments businesses send against invoices.
  • Person-to-person transfers, including moving money between your own accounts at different banks.

What You Need to Send One

Before you can push a payment, you need a short list of details about the receiving account. Getting them exactly right the first time avoids delays and returned-item fees.

  • The recipient’s full legal name as it appears on the receiving account.
  • The name of the recipient’s bank.
  • The nine-digit routing number for that bank, found on the bottom left of a paper check or confirmed by the bank directly.
  • The account number for the specific account receiving the funds.
  • Whether that account is a checking or savings account.

Verify these against an official document like a voided check or a direct deposit form from the recipient’s bank. If the routing or account number is wrong, the transfer will bounce back, and your bank may charge a returned-item fee of roughly $10 to $40, depending on the institution. Most banks also let you add a short memo so both parties can identify the payment on their statements.

How to Send an ACH Push

Most banks let you set up an ACH push from their online banking portal or mobile app. After signing in, go to the transfers or payments section and enter the recipient’s banking details. A confirmation screen will show the recipient’s name, the amount, and the date the transfer is scheduled to leave. You authorize the payment by clicking a final confirmation button.

Once you confirm, your bank issues a transaction ID you can use to track the payment, and many banks send an email or app notification as a receipt. Expect a temporary hold on the funds while the transfer settles, so the money will show as unavailable in your balance before it actually arrives at the receiving bank. Some banks charge a small outgoing fee, usually $0 to $3, though many major banks offer standard ACH pushes for free.

Transfers from a personal account are covered by the Electronic Fund Transfer Act and its implementing rule, Regulation E, which gives you the right to dispute errors and unauthorized transfers.3eCFR. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E)

When the Money Arrives

A standard ACH push typically takes one to three business days to reach the recipient’s account. The actual timing depends on when you submit the transfer relative to your bank’s cutoff and whether you chose standard or expedited processing.

The ACH Network does not process payments one by one. It processes them in batches during set windows each business day. For Same-Day ACH, there are three windows, with submission deadlines around 10:30 a.m., 1:00 p.m., and 4:00 p.m. Eastern Time.4Nacha. ACH Schedules and Funds Availability Miss a cutoff and your transfer rolls into the next window; miss the final window of the day and it is treated as if you started it the next business day.

Weekends and federal holidays pause the settlement cycle because the ACH operators do not process transactions on those days. A transfer you start Friday evening generally will not begin moving until Monday, and if Monday is a federal holiday, it waits until Tuesday.

Same-Day ACH if You Need It Faster

Same-Day ACH can deliver the payment by the end of the same business day if you meet a few conditions. The per-transaction limit is $1 million.5Nacha. Same Day ACH Nearly all ACH payment types qualify, with a few exceptions including international ACH transactions and certain non-standard entry types.6Nacha. Same Day ACH – Moving Payments Faster (Phase 1)

Your bank must submit the payment before one of the three daily Same-Day cutoffs for it to settle that day. The RDFI must make funds available by 5:00 p.m. local time for first-window payments, or by 9:00 a.m. the next morning for payments processed in the final window.4Nacha. ACH Schedules and Funds Availability Some banks charge an extra fee for same-day processing; the amount varies.

ACH Push vs. Wire Transfer

Wires and ACH pushes both move money from one bank account to another, but they differ in several ways that matter when you are choosing between them.

  • Speed. A domestic wire typically arrives the same day, often within hours. A standard ACH push takes one to three business days, and Same-Day ACH closes much of the gap.
  • Cost. ACH transfers are usually free or a few dollars. Domestic wires commonly cost $25 to $35 for the sender and sometimes carry a receiving fee as well.
  • Reversibility. ACH pushes can be reversed under limited conditions, discussed below. Wires are generally final once sent, and recovering a wire sent to the wrong account is extremely difficult.
  • Dollar limits. Same-Day ACH caps individual transactions at $1 million. Wires have no standard network-wide cap, though your bank may impose its own limits.

For routine payments like payroll, vendor invoices, and account-to-account transfers, ACH is the cheaper choice. Wires make more sense when you need guaranteed same-day finality or are moving very large sums.

ACH Push vs. FedNow

FedNow is a real-time payment service operated by the Federal Reserve. Unlike ACH, which processes in batches during business hours, FedNow settles transactions individually, around the clock, every day of the year, including weekends and holidays.7FedNow Explorer. Instant Payments and P2P Transactions The recipient sees the funds within seconds.

The FedNow network transaction limit rose to $10 million in November 2025, though individual banks can set lower limits based on their own risk policies.8Federal Reserve Financial Services. FedNow Service Raises Transaction Limit to $10 Million Like ACH pushes, FedNow only supports push transactions. The catch is coverage: not every bank participates yet, so whether you can use it depends on both your bank and the recipient’s bank.

Canceling or Reversing an ACH Push

Once you confirm an ACH push, stopping it gets hard quickly. If you catch the mistake before your bank’s cutoff, you may be able to cancel through online banking or by calling customer service. After the payment has gone to the ACH Network, the rules tighten.

Under Nacha’s rules, an originator can reverse an ACH credit entry only for specific reasons:

  • The payment was a duplicate of an earlier transaction.
  • The dollar amount was wrong.
  • The payment went to the wrong recipient.
  • The payment was scheduled for the wrong date.

The reversal must reach the RDFI within five banking days after the original transaction’s settlement date.9Nacha. ACH Network Rules – Reversals and Enforcement A reversal is not allowed because you changed your mind, and it is not allowed because your account lacked sufficient funds. Even when a reversal qualifies, the receiving bank is not required to return money if the recipient’s account has been closed or no longer has the balance. Acting quickly matters.

Your Protections if Something Goes Wrong

If someone makes an unauthorized transfer from your personal account, Regulation E caps your liability based on how quickly you report it.10eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers

  • Reported within 2 business days: maximum liability of $50.
  • Reported after 2 business days but within 60 days of your statement: maximum liability of $500.
  • Reported after 60 days: you could be liable for the full amount of any unauthorized transfers that occurred after the 60-day window, with no cap.

These protections apply to personal accounts. Business accounts are a different world. They are generally governed by Article 4A of the Uniform Commercial Code rather than Regulation E, and the rules are less favorable. If a business’s bank has a commercially reasonable security procedure in place and follows it, the bank may not be liable for an unauthorized transfer even if the business did not actually authorize it. Business account holders typically have one year to object to a questionable transaction, but the burden of proof is heavier than it is for consumers.
