ACH Reversals, Returns, and Reclamation: Deadlines and Reg E

ACH reversals, returns, and reclamation are three separate correction processes with three separate clocks. A reversal is the originator’s tool and must reach the receiving bank within five banking days of settlement. A return is the receiving bank’s tool, with two banking days for most commercial errors and up to 60 calendar days for unauthorized consumer debits. Reclamation is the Treasury’s tool for recovering federal benefit payments made after a recipient’s death, and it runs on its own 120-day deadline under 31 CFR Part 210. Which process applies to you depends on who is trying to undo the payment and why.

Reversing an ACH Entry You Sent

If you originated an ACH entry that went out wrong, Nacha rules let you transmit a reversing entry, but only for a short list of reasons. The permitted grounds are a duplicate entry, an entry sent to the wrong receiver, a wrong dollar amount, certain payroll credits tied to employment termination, and timing errors where a debit posted earlier than intended or a credit posted later than intended.¹ A reversal sent for any other reason violates the rules and can be returned as improper or trigger an enforcement complaint.

The reversing entry has to reach the receiving bank within five banking days after the settlement date of the original transaction.¹ After that, the standard reversal path closes. Recovery then has to go through direct negotiation with the receiver or legal action outside the ACH system.

You also have to notify the receiver of the reversal and the reason for it no later than the settlement date of the reversing entry. And keep your documentation. If the reversal is challenged later, the records showing why the original entry qualified as erroneous are what defend the correction.

Returning an ACH Entry You Received

Returns move in the opposite direction. The receiving bank sends the entry back to the originating bank, and the deadline depends on the reason.

Two Banking Days for Standard Returns

Most administrative returns have to reach the originating bank by the opening of business on the second banking day after settlement. This covers the common codes: insufficient funds (R01), closed accounts (R02), accounts that cannot be located (R03), and invalid account numbers (R04). The window is tight. For a business account, if something looks wrong on the day it posts, the bank needs the dispute flagged the same day to have any realistic chance of returning it through normal ACH processing.

Sixty Days for Unauthorized Consumer Debits

Consumer accounts get a much longer window when the debit itself was not authorized. The receiving bank can return the entry for up to 60 calendar days from the date the statement showing the transaction was made available to the customer.² Four return codes qualify:

R05, a corporate-formatted debit hitting a consumer account without authorization
R07, authorization previously given but revoked
R10, the consumer does not know the originator or never authorized the debit
R11, the transaction does not match the terms the consumer agreed to

Before the bank can process one of these extended returns, it has to obtain a Written Statement of Unauthorized Debit from the consumer, signed under penalty of perjury.² Many claims stall here. The call to the bank does not fix anything on its own; the signed statement has to come in before the return can move. Once the 60-day window closes, the right to a mandatory return through the ACH network is gone, and recovery means dealing with the originator directly or going to court.

Same Day ACH Shifts the Clock

For entries processed through Same Day ACH, the return deadline moves one day earlier because the original entry settles one day sooner.³ The practical effect is less time to catch a problem before the return window shuts.

When a Reversal Looks Wrong on Your End

If you receive a reversal that should not have been sent, the receiving bank can push it back. A reversal is improper if the stated reason is not on Nacha’s permitted list, the reversal came in after five banking days, or the originator used a reversal to patch a funding problem on the original entry.¹

The path depends on the account:

On a consumer account, the receiving bank returns the improper reversal under R11 after obtaining the Written Statement of Unauthorized Debit, and the return has to reach the originating bank by the opening of business on the banking day after the 60th calendar day following the improper reversal’s settlement date.¹
On a business account, the bank returns the entry under R17 by the opening of business on the second banking day after the reversal settled.¹

The business deadline is the one that catches companies off guard. Two banking days means a questionable reversal has to be identified and acted on almost immediately.

Consumer Rights Under Regulation E

Nacha rules govern the ACH network, but Regulation E is federal law and gives consumers a separate layer of protection on electronic fund transfers. It applies regardless of whether the bank handles the dispute through an ACH return or through its internal process.

How Fast You Report Decides What You Owe

Liability for unauthorized transfers on a consumer account is tiered by timing:⁴

Report within two business days of learning about the unauthorized transfer, and your liability caps at $50.
Report after two business days but within 60 days of the statement being sent, and the cap rises to $500.
Wait longer than 60 days and you can be liable for the full amount of unauthorized transfers that happen after the 60-day period.

The 60-day clock starts when the bank sends the statement showing the unauthorized transfer, not when you open it. That is the expensive detail. Statements that sit unread are statements whose protection window is quietly running out.

What the Bank Has to Do Once You Report

Your bank has to investigate and reach a decision within 10 business days of your report.⁵ If it needs more time, it can take up to 45 days, but only if it provisionally credits your account within those first 10 business days. The bank can hold back up to $50 of that provisional credit if it reasonably believes an unauthorized transfer occurred and you had some responsibility under the liability rules.

Three situations extend the investigation window to 90 days: point-of-sale debit card transactions, international transfers, and transactions on new accounts within the first 30 days. For new accounts, the deadline for provisional credit also stretches to 20 business days.⁶

Stopping a Recurring Debit Before It Posts

Stopping a future debit is simpler than clawing back one that already settled. Under Regulation E, you can stop a preauthorized electronic fund transfer by notifying your bank at least three business days before the scheduled date.⁷ The notice can be oral or written, though if you call it in, the bank may require written confirmation within 14 days. Miss that confirmation and the oral stop payment lapses.

Stop payment orders on consumer ACH debits do not expire after six months the way they do for checks and business ACH entries. The block stays active until you withdraw it or the bank returns the entry, and if the originator resubmits, the bank has to keep blocking it. Telling the originator to stop charging you is a separate step and does not substitute for the stop payment at your bank. Do both.

Federal Benefit Reclamation

Reclamation sits outside the Nacha framework entirely. It is how the federal government recovers benefit payments deposited after a recipient dies or becomes legally incapacitated, and it operates under 31 CFR Part 210 and the Treasury’s Green Book.⁸ The agency sends a Notice of Reclamation directly to the bank that received the deposit, demanding return of payments that should not have been made.

Agency Deadline

The federal agency has 120 calendar days from when it first learns of the death or incapacity to initiate reclamation.⁹ Payments made more than six years before the reclamation notice generally cannot be recovered, with an exception if the current account balance exceeds the total of payments from that six-year window.

What the Bank Owes

A bank that had no knowledge of the recipient’s death when it credited the payments can limit its liability, but only by meeting several certification requirements. It must certify no actual or constructive knowledge of the death at the time the payments were credited or withdrawn, and it must provide the names, addresses, and phone numbers of the account holder, any co-owners, authorized signers, and anyone who withdrew funds after the death.¹⁰

With limited liability established, the bank owes the lesser of the account balance at the time it receives the notice (plus up to one business day to act) or the total outstanding overpayment. If the agency cannot collect the full amount from the account, the bank faces additional liability for benefit payments received within 45 days after the recipient’s death, up to the remaining balance owed.¹⁰

Banks that fail the certification requirements or do not comply with the process become liable for the full overpayment regardless of the account balance. If the bank does not return the amount owed in time, the Treasury instructs the Federal Reserve Bank to debit the funds directly from the bank’s account.⁹ There is no negotiation at that stage.

What You Need to Submit a Reversal or Return

Bad data on a request is one of the fastest ways to lose the recovery window. Every ACH entry carries a 15-digit trace number, formed from the first eight digits of the routing number plus a seven-digit sequence number, and that trace number is the primary identifier for pulling the transaction through the system.¹¹ You will find it on your bank’s transaction report or in the ACH file itself.

You also need the exact settlement date, the precise dollar amount to the cent, the Standard Entry Class code (PPD for personal payments, CCD for business transactions, WEB for internet-initiated entries), and the correct return or reversal reason code. Any mismatch with the original entry data can cause the receiving bank’s system to reject the request outright. Cross-reference your records against your statement before you submit, and confirm the account holder name and account number line up with the original transaction.

Financial institutions have to retain ACH records for six years from the date of receipt or transmission.¹² Keep your own records at least as long. If a dispute surfaces years after settlement, the trace number and the original file data are often the only things that resolve it.
