ACH limit guide: All you need to know in 2025
Understand ACH limits, factors affecting them, and how to increase your limit. Learn about common ACH limit ranges and fraud prevention.
ACH payments offer a lot of advantages for your business.
They are a convenient and cost-effective way to pay bills and get paid by customers.
Let’s compare ACH vs wire transfer, for example. ACH has much lower fees, and if you need speed, same-day ACH payments are available. While they’re more costly than regular ACH, they are still a better value than wire transfers. Plus ACH payments can be scheduled automatically, taking some of the load off your accounts payable team.
But with all these advantages, ACH has its limits too—and not just figuratively! ACH transactions are capped by ACH limits that dictate the maximum permitted amount to send or receive.
If you’re considering using ACH transfers for your business, then read on to discover all you need to know about ACH limits.
What is an ACH transfer?
ACH transfer is a payment method where funds are transferred electronically between banks or financial institutions. ACH payment transactions are handled by the ACH (Automated Clearing House) network and regulated by the US federal government.
ACH is a very popular way to receive or send payments, especially in the B2B world. According to Nacha, the organization that oversees ACH transfers, there were 8.4 billion payments made via ACH in Q3 2024, amounting to $21.5 trillion. ACH transfers are commonly used to pay vendor and supplier bills, payroll, insurance claims, and for government payments, such as taxes and benefits.
It’s important to note that ACH and international payments are two different methods. ACH is typically only available for payments within the US, while international payments are used to transfer money to vendors or suppliers outside the US. Most US banks don’t support international ACH transfers.
How long does an ACH transfer take? Standard ACH payments take up to 3 business days, while same-day ACH is processed and cleared on the same day, and comes with a higher fee.
ACH transfers have set limits indicating the maximum dollar amount that can be sent in a single transaction or on one day. Businesses should get to know the various rules dictating the ACH transfer limit so they can choose the best method and bank to suit their needs.
How do ACH limits work?
ACH payments are an electronic, automated payment method that operates via the ACH network, connecting banks and managing the flow of funds between them. ACH limits automatically restrict the transaction amount according to predefined rules.
When an ACH transaction is initiated, the payer’s bank will only allow an amount up to the ACH limit; if the payment amount is too large, it won’t be authorized.
For example, imagine a business that mostly opts to pay bills with ACH. The business recently underwent renovations in their retail store, and they owe the contractor $12,000 for the work.
However, the ACH limit per day is $10,000. If the business initiated the ACH transfer for the full amount, it would be rejected. In these circumstances, the business could negotiate to pay the bill via ACH transfer in two separate transactions, one day after the other. This way, they can enjoy the benefits of ACH (fast online payment, low fees, no paper checks needed) while staying within the ACH limit.
Who sets ACH limits?
ACH payment processing is governed by comprehensive rules and regulations, set by the Nacha organization in compliance with federal and financial laws.
While Nacha allows ACH transfers of up to $1 million per transaction, many banks are much stricter, setting the ACH limit to just a few thousand dollars. When it comes to defining what is ACH limit, the decision is ultimately up to the various banks and financial institutions that offer ACH payments as a service, in compliance with Nacha rules and the law.
Factors affecting ACH limits
There are several factors that impact the ACH withdrawal limit. Let’s take a look at each in turn.
Account type (personal, business, premium)
Different types of bank accounts have varying rules and conditions, including ACH limits. Business accounts are designed to meet the needs of businesses rather than private individuals. They typically offer larger limits on allowed amounts for money transfers.
Savings accounts are generally not set up to allow for a large volume of ACH transactions. Businesses or individuals who require frequent ACH payments should choose another account type, like a checking account, to handle these payments.
Financial institution policies
Each bank or financial institution has their own policies for the ACH limits. What is the maximum ACH transfer for the main banks in the US? According to My Bank Tracker, it ranges from $1,000 per transaction (Bank of America), to $10,000 per transaction or up to $25,000 a day (Chase), and $2,000 per day or $10,000 per month (Citibank).
Depending on their ACH transaction volume, business owners should check the different financial institutions and choose one that meets their needs—see below for a more detailed chart of ACH limits by bank.
Transaction type
Various types of transactions have different ACH limits. The same day ACH limit, for example, was increased by Nacha in 2022 from $100,000 to $1,000,000 in response to consumer demand for larger instant payments for easier business transactions .
Banks typically allow higher limits on how much a business can receive via ACH (ACH credit) compared to how much they can send (ACH debit). ACH debits, which involve drawing money from the payer’s account, often have lower limits because the risk to the bank is higher.
Security measures
Financial institutions take all kinds of measures to reduce fraud. Limiting the ACH transaction amount helps to contain the risk of cybersecurity attacks, theft and loss. Also, ACH transfers can be reversed, so setting a limit on ACH payments helps to reduce the negative impact on liquidity if errors occur and money must be refunded.
Additionally, banks and financial institutions are subject to anti-money laundering laws. Enforcing ACH limits makes it easier to monitor money transfers and ensure compliance.
Common ACH limit ranges
ACH limits for personal accounts and business accounts vary considerably from bank to bank or from processor to processor. Some banks do not have a set limit but determine the ACH limit according to the account owner’s history and activity.
Limits are typically set per transaction, per day, or per month.
ACH limit ranges start from around $1000 per transaction to upwards of $25000 per day.

Increasing your ACH limit
Although ACH limits are set by the bank, they aren’t necessarily set in stone. For businesses with a good financial standing and track record, it’s possible to negotiate with the bank or payment provider to increase the ACH limit. Here are some things you can try if you want to increase your ACH limit and transaction volume:
- Get in touch with the bank: There’s no better way than to ask directly. Contact your bank representative, discuss your needs, and find out whether it’s possible to customize your ACH limit.
- Show a strong financial history: Banks are, understandably, in the business of reducing risk. If your business can show a consistent transaction history, stable cash flow, and good overall credit score, they may be more inclined to increase your ACH limit.
- Back up your claims with documentation: Come armed with recent financial statements, projected transaction volume, and any other documents that can strengthen your case for a higher ACH limit.
- Take care of your relationship with the bank: You are more likely to receive an ACH limit increase (and other requests) if you have a long-standing and solid relationship with your bank. Banks that know and trust your business will naturally be more flexible with you.
- Request a temporary increase: You may be able to secure a temporary increase during a particularly high volume transaction period. This can help to convince the bank that you are responsible with your finances and ACH usage and set the stage for a permanent increase of your ACH limit.
ACH limit exceptions and overdrafts
When a business initiates an ACH payment, ideally there are enough funds in the account to cover it. However, with multiple outgoing payments, this can be difficult to track. Banks and financial institutions impose ACH limits to help reduce the risk of insufficient funds and overdrafts. This is good for the bank and good for your business.
At the same time, there may be periods in which a business needs to send or receive a high volume of ACH transactions, and ACH limits can hamper the process.
A good tactic for ACH limit exceptions is to be transparent with your bank. If you are anticipating a large incoming or outgoing ACH payment, let them know in advance so they can process it quickly to prevent overdrafts, delays, or other issues.
ACH limits are a built-in safeguard designed to make accounts payable and receivable more secure and less risky—consider them your friend rather than foe. But don’t be shy about communicating with your bank or payment provider so they can optimize the ACH limits where possible.
