ACH Rule Update


The ACH Rule revisions for 2023 do not affect our ACH originators.

Here are some reminders of prior year rules changes:

Effective on January 2, 2021 (Enforcement Rule)

Effective on June 30, 2021 (Reversal Rule)


This change impacts Financial Institutions as well as Originators and Receivers

This Rule will define an Egregious Violation as:

  • A willful or reckless action, and involves at least 500 Entries, or involves multiple Entries in the aggregate amount of at least $500K
  • Allow the ACH Rules Enforcement Panel to determine whether a violation is egregious, and to classify an Egregious Violation as a Class 2 or 3 Rules Violation.
  • The sanction for a Class 3 violation can be up to $500,000 per occurrence and a directive to the ODFI to suspend the Originator or Third-Party Sender. It also expressly authorizes NACHA to report Class 3 Rules violations to the ACH Operators and industry regulators.

This Rule will explicitly address improper uses of reversals. It will expand the permissible reasons for a reversal to include a wrong date error – 1) the reversal of a debit Entry that was for a date earlier than intended by the Originator, or 2) a credit Entry that was for a date later than intended by the Originator

The Rule will also establish formatting requirements for reversals, beyond the current standardized use of the Company Entry Description field (REVERSAL):

  • The Company ID, SEC Code, and Amount fields of the reversal must be identical to the original entry.
  • The contents of other fields may be modified only to the extent necessary to facilitate proper processing of the reversal.
  • This is the same approach as the formatting requirements for Reinitiated Entries

Effective on September 17, 2021


This change impacts Originators and TPSP (including TPS)

The overarching purpose of these rules is to improve and simplify the ACH user-experience by facilitating the adoption of new technologies and channels for the authorization and initiation of ACH payments.

Standing Authorization

This rule will define a Standing Authorization

  • Under existing guidelines, consumers may authorize the Originator to debit their account as a Single-Entry (one-time) payment or Recurring (regular intervals.) Future entries that do not align with the terms of the original request would require the Originator obtain an additional authorization.
  • Under the new Rule, Standing Authorizations may be obtained when the payment is not a Single-Entry but does not into the Recurring model, and enable businesses and consumers to make more flexible payment arrangements for relationships that are ongoing in nature. Standing Authorizations may be collected in writing or orally.
  • Payment Type Codes:
    • R = Recurring
    • S = Single Entry
    • ST = Standing Authorization

Other Authorization Proposals

In conjunction with the other authorization rules (Standing Authorizations and Oral Authorizations), this Rule includes other modifications and re-organizations of the general authorization rules for purposes of clarity, flexibility and consistency.


  • Re-organizes the general authorization rules to better incorporate Standing Authorizations, Oral Authorizations, and other changes described below
  • Defines Recurring Entry to complement the existing definition of Single Entry and the proposed new definition of Subsequent Entry, and align with terms in Regulation E


  • Explicitly states that authorization of an ACH payment by any method allowed by law/regulation
  • Only consumer debit authorizations require a writing that is signed or similarly authenticated


  • Applies the standards of readily identifiable and clear and readily understandable terms to all authorizations
  • For all consumer debit authorizations, applies the minimum data element standards that are currently stated only in the TEL rules (i.e., what will be in a consumer authorization)

Originators must respond to Notifications of Change by making corrections within six banking days of receipt of the NOC information or prior to initiating another entry to the Receiver account, whichever is later. (Note: Special requirements apply to NOCs received in response to prenotification entries and to Single Entries. These are discussed in more detail below.)

NOC received in response to a prenotification entry

  • An Originator must make all changes contained within an NOC related to a prenotification entry; however, the Originator timing requirements for action can differ, depending on when the NOC is made available to the ODFI. For a timely NOC (that is, an NOC made available to the Originator ODFI by the ACH Operator by the opening of business on the second banking day following the prenote settlement date), the Originator must make the requested changes before transmitting a live entry to the Receiver account. For an untimely NOC (that is, an NOC made available to the ODFI by the ACH Operator after the opening of business on the second banking day following the prenote settlement date), the Originator must make the requested changes within six banking days of receiving the NOC information from its ODFI or prior to transmitting the next entry, whichever is later

NOC Received in response to a Single Entry

  • By definition, a Single Entry is a credit or debit entry based on a Receiver authorization for a one-time transfer of funds to or from the Receiver account. No subsequent entries may be originated unless separately authorized by the Receiver via a new authorization. The NACHA Operating Rules, therefore, allow an Originator discretion in determining whether to make the changes requested in any NOC related to an Entry identifiable as a Single Entry.
