ACH transfer limits are the maximum dollar amounts you can move through the Automated Clearing House network in a single transaction, a day, or a month. Most personal checking accounts cap outgoing ACH transfers somewhere between $2,000 and $25,000, and those numbers come from your bank’s internal risk policies rather than federal law. Sitting above every bank’s cap is a network-level ceiling set by NACHA: $1 million per Same Day ACH transaction as of March 2022.1Nacha. ACH Payments Fact Sheet What you can actually send depends on which layer bites first, and for most people it’s the bank.
What Your Bank Actually Allows
Banks set ACH limits as internal policy. Federal regulations require them to disclose that limits exist, but the specific dollar figures are up to each institution and often aren’t published on their websites for security reasons.2eCFR. 12 CFR Part 205 – Electronic Fund Transfers (Regulation E)
For a standard personal checking account, daily caps commonly land between $2,000 and $5,000. Monthly limits stretch wider, often between $10,000 and $25,000 across a rolling 30-day window. These are rough ranges, not universal rules. One bank might let you send $10,000 a day from a basic account while another holds you at $2,500 for the same product. The only reliable way to know your number is to ask your bank directly.
Business Accounts Run on Different Numbers
Commercial accounts operate under substantially higher thresholds because they have to. A company running biweekly payroll for 50 employees can’t function on a $5,000 daily cap. Business checking accounts routinely carry ACH limits of $50,000 or more, and larger companies negotiate custom limits based on revenue and transaction history. In return, banks require more documentation up front — formation papers, EIN verification, financial statements — and may review the account’s activity on an ongoing basis. If a business needs to move more than even an elevated limit allows, most commercial banking teams will set up a transfer schedule or a standing arrangement for recurring high-value payments.
The NACHA Ceiling Above Your Bank
Every ACH payment in the country runs under NACHA’s Operating Rules, and NACHA sets its own maximum for Same Day ACH: $1 million per transaction. The network raised that cap in stages, going from $25,000 to $100,000 in March 2020 and then to $1 million effective March 18, 2022.1Nacha. ACH Payments Fact Sheet Standard (non-same-day) ACH transactions have no per-item dollar cap at the network level, though individual banks still apply their own.
The important thing to understand about the $1 million figure: it’s the maximum the network can carry, not a right you can exercise. Your bank’s internal limit almost always cuts in well below that. The network cap matters most for large business payments, real estate settlements, and institutional transfers where both banks have agreed to move at higher thresholds.
Money Coming In vs. Going Out
Direction changes everything. Outbound transfers (money leaving your account) carry the strictest caps because they represent the most risk to the bank. Once money is gone, recovering it from a fraudulent or mistaken transfer is difficult and sometimes impossible.
Inbound transfers face much higher limits or none at all. Deposits are easier to verify after the fact, and if an incoming ACH turns out to be fraudulent, the bank can freeze or reverse the funds. That asymmetry is why your employer’s direct deposit of any size clears without issue, while you might hit a wall trying to send $5,000 to a friend at another bank.
Raising Your Limit
If your current cap is too low for something like a real estate closing or a large business payment, most banks will consider raising it. The process usually means calling your bank or visiting a branch. The factors that matter are the ones you’d expect: how long you’ve held the account, your average balance, and whether you’ve had overdrafts or returned items.
Account tenure is often the biggest lever. New accounts typically face reduced limits during an initial probationary period of 30 to 90 days while the bank watches your transaction patterns. After that window, limits usually increase on their own if nothing has gone wrong. Verification methods matter too. Linking an external account through micro-deposits or an instant-verification service reduces processing-error risk and can unlock higher allowances. Some banks tie higher thresholds to enrollment in identity-verification programs like two-factor authentication or device-linked security codes.
Working the other direction, a history of non-sufficient funds returns or frequent overdrafts acts as a persistent red flag. Banks may permanently lower your ACH limits in response, and rebuilding that trust takes time and consistent positive activity.3FDIC.gov. Overdraft and Account Fees If you know you’ll need to make large transfers regularly, ask about limits before you open the account.
What Happens When You Hit the Cap
When you try to send an ACH transfer that exceeds your per-transaction or daily limit, the bank almost always rejects it outright. You typically won’t face a penalty fee just for attempting a too-large transfer. The payment simply doesn’t go through, and you usually get a notification explaining why. The real cost lands on the receiving end: if a payee was counting on that money, you may owe late fees or damage a business relationship.
A failed transfer for lack of funds is a different problem. Your bank may charge a non-sufficient funds fee, commonly around $35 per occurrence.3FDIC.gov. Overdraft and Account Fees The party you were trying to pay may also charge a returned-payment fee, which varies by state but generally runs between $25 and $50. Those costs compound quickly across multiple payments.
Do Not Split a Transfer to Get Around a Limit
This one deserves its own warning. Federal law requires banks to file a Currency Transaction Report for any transaction over $10,000. Deliberately breaking a large transfer into smaller chunks to dodge that reporting threshold is called “structuring,” and it’s a federal crime even if the money itself is entirely legitimate.4Office of the Law Revision Counsel. 31 US Code 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
A structuring conviction carries up to five years in prison, a fine, or both. If the structuring ties to other illegal activity involving more than $100,000 within a 12-month period, the maximum jumps to 10 years.4Office of the Law Revision Counsel. 31 US Code 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited Banks are trained to spot the pattern. Three transfers of $4,500, $4,800, and $4,900 across three days can trigger a Suspicious Activity Report to the Financial Crimes Enforcement Network on their own, regardless of what you intended.
The practical takeaway: if you need to send $15,000, send $15,000. The reporting itself is routine and doesn’t flag you for an audit or investigation. Splitting the payment to avoid perceived hassle is what creates the legal exposure.
When ACH Isn’t Enough: RTP and FedNow
If the $1 million Same Day ACH ceiling or your bank’s own cap doesn’t cover what you need to move, two newer payment rails offer higher limits and true real-time settlement. The Clearing House’s RTP (Real-Time Payments) network raised its per-transaction ceiling to $10 million in February 2025. The Federal Reserve’s FedNow service matched that figure, moving its own limit from $1 million to $10 million effective November 2025.5Federal Reserve Financial Services. FedNow Service Raises Transaction Limit to $10 Million
Both networks settle payments in seconds rather than hours and operate 24/7, including weekends and holidays. The catch: not every bank participates yet, and individual banks still set their own limits below the network maximum. For time-sensitive, high-value payments, though, these rails are increasingly the better option over ACH.
