Returned ACH payments represent a troublesome interruption that causes your company to waste resources and funds. So, why do ACH returns occur? The main causes of ACH returns are incorrect bank information, insufficient account balances, inactive accounts, or suspected fraudulent transactions. Being well-versed in and keeping an eye on ACH returns is very important for a flawless payment system and for ensuring that you don’t face any hiccups in your cash flow.
Throughout this post, we’ll cover what an ACH return is and the reasons behind ACH returns, and we will provide you with action points to handle them effectively.
What is an ACH Return?
The response message from the receiving bank is known as an ACH return, which alerts you to an ACH payment failure. This results from the bank’s inability to handle ACH transaction requests or demands.
Among the most often occurring causes could be inadequate funds, improperly entered account information, or the consumer claiming they did not authorize the transaction.
ACH Return vs. ACH Reversal: How They Differ
An ACH return is different from an ACH reversal. An ACH reversal is a request to cancel a completed transaction, and it must be initiated within five banking days after the original transaction. ACH returns are most commonly known as rejected payments, like bounced checks.
How does an ACH return work?
The recipient bank (also referred to as the Receiving Depository Financial Institution or ‘RDFI’) sends a return entry through the ACH network to the originating bank (also known as the Originating Depository Financial Institution or ‘ODFI’), which reverses the transaction when an ACH return occurs. The RDFI provides a return code that identifies the reason for the return.
The ODFI will alert the originator and can levy a fee for the return of the transaction. To resolve the problem, the ODFI might also try to resend the payment or personally get in touch with the customer—for instance, if the customer’s account is suspended or their banking information is inaccurate.
Step-by-step breakdown of the ACH return process
Let’s walk through the process:
- The RDFI informs the ODFI of the return, meaning that the particular ACH transaction cannot be received. The return also contains a return code that specifies the reason for the return.
- The originator is notified of the return and the return reason by the ODFI. The money from the original payment is sent back to the receiving bank. In case the return resulted from incorrect bank account details, the RDFI may also provide the ODFI with a Notification of Change (NOC) to enable the ODFI or originator to update the bank account data for future payments.
- Depending on the bank’s policy, the ODFI might charge a fee for the returned payment.
- Once the originator resolves the problem by updating the account information or verifying that their customer’s account exists, they may decide to send the payment once more.
Since no two banks are the same, it is advisable to find out your bank’s specific ACH return policy.
Common Issues That Lead to ACH Returns
Various return reasons cause ACH payments to be returned with different specific codes.
- Insufficient Funds R01: The recipient’s account lacks enough funds to cover the transaction.
- Closed Account R02: The transaction was returned due to a closed account.
- No account or unable to locate account R03: The account number does not match any currently active account. This error is similar to issues with invalid account numbers, even though it often involves nonexistent accounts.
- Invalid account number R04: The account number shown in the ACH entry is either wrong or poorly formatted.
- Unauthorized R07, R10: The account holder did not correctly authorize the transaction or had revoked approval.
- Stop payment order R08: The account holder has set up a stop payment order on an ACH debit.
- Account holder deceased R15: Upon learning of the death, financial institutions typically cease handling any further transactions.
What is an ACH Return Fee?
Usually, the original bank charges the originator—that is, the merchant—a fee to pay for the administrative expenses related to handling the ACH return. You would pay a fee for a bounced check, and this rate is comparable. Different fee amounts mean that you should ask your payment processing partner (or individual bank) about certain ACH-related fees.
What are the consequences of excessive ACH returns?
Typically, there is a fee for each ACH return, and a careless approach to ACH payments can result in increased expenses on a large scale.
Because payments do not reach their intended locations, improper handling of your ACH transactions might cause cash flow problems. If you are, for example, late in paying suppliers, your company may find itself in debt.
Here are a few more consequences:
Fines and penalties
Nacha (National Automated Clearing House Association), the ACH governing body, tracks the frequency of ACH returns received by originators. If you exceed any of the return rate thresholds—0.5% for unlawful payment return codes, 3% for administrative return codes, or 15% overall—your company may suffer serious penalties.
Serious violations might cost you up to $500,000 in fines; you might even be suspended from all originating ACH transactions.
Negative impact on customer satisfaction
It can disturb consumers if the company engages in negative practices like multiple failed ACH transfers or a refund process that does not meet customer satisfaction.
How to Handle High ACH Return Volumes
Handling large ACH return volumes can be challenging. However, with an organized strategy, companies can minimize the downsides and, at the same time, optimize their payment systems.

Preventive Strategies
- Before starting payments, confirm account accuracy using robust verification methods such as micro-deposits or outside third-party verification services.
- Use data validation tools and software to check consumer data, like routing numbers and account numbers, to reduce mistakes.
- Clearly explain the fees and implications of returned payments to inspire consumers to verify their data twice.
Efficient Return Processing
- Make investments in tools that automatically send internal reports and consumer notifications, including software for returns. Such investments can save significant time and money.
- For consistency and efficiency, define explicit procedures for managing returns and defining roles and duties at every stage of the process.
- To ease data reconciliation and reporting, connect your accounting or customer relationship management (CRM) software with your payment processing system.
Customer Engagement
- Notify consumers right away about returned payments, then explain the reason and offer direction on how to resolve the problem.
- Give consumers who have experienced several ACH returns other payment options, including credit cards and debit cards.
- For consumers having temporary financial problems, think about providing grace periods or flexible payment schedules.
Performance monitoring and optimization
- Track your return rates regularly, then create benchmarks to gauge development.
- Examine return data to identify areas of consistent problems or payment processing improvement needs.
- Please gather feedback from staff and clients to identify issues and potential solutions.
External Support Solutions
- Work with a payment processor with strong return management tools and support that specializes in ACH processing.
- Should you have a lot of unpaid returned goods, you might want to work with a collections firm to settle outstanding debt.
- Consult professionals in the field or consultants focused on ACH compliance and optimization for direction.
Effective strategies for managing ACH returns
These best practices should enable you to control and reduce ACH refunds.
Understand your ACH return codes
- Please ensure your team is familiar with the meaning of each ACH return code and how to handle them effectively.
- It is important for policy reviews to be done regularly so that they align with the latest standards and regulations.
Verify bank details
- Before handling transactions, validate bank information with small test deposits.
- Just imagine if you used a bank details checking service that does it in real-time. Such a procedure would lead to a big reduction in the return rate.
Stay in contact with customers
- Let clients know when you will debit their accounts in advance to give them time to check their balance.
- Share their obligations and the ACH process with clients to help reduce unauthorized returns and misunderstandings.
- Deal with problems quickly to satisfy clients and avoid more.
Obtain proper authorization
- Always get written client approval for the withdrawal amount and schedule. Keep these records to rapidly address any conflicts.
Monitor for patterns
- Watch returns to evaluate whether a consistent issue calls for correction.
- Examine return data and highlight underlying causes to help prevent future difficulties.
Be aware of fees
- Please calculate the expenses associated with ACH returns and incorporate them into your budget.
- If you frequently conduct transactions, please consider requesting your bank to negotiate more favorable fee conditions.
Leverage technology
- Use technology to automate the tasks where possible so that you can reduce errors and make the transaction process more convenient.
- Integrate your payment system with the accounting software you are using to get more reliable data and reduce the chance of mistakes.
In conclusion, better ACH return management, including return code analysis, account checks, and quick communication with customers, can help reduce transaction rejections and avoid penalties from Nacha. At the same time, a company needs to commit to making it happen, treat it as a good practice, and keep its finances in check.
