NACHA Operating Rules

The ​Nacha Operating Rules are the foundation for every ACH payment. By defining the roles and responsibilities of financial institutions and establishing clear guidelines for each Network participant, the Rules ensure that millions of payments occur smoothly and easily each day. 

Featured Rules

Supplementing Fraud Detection Standards for WEB Debits

The effective date for an upcoming change in the Nacha Operating Rules is being extended by the Nacha Board of Directors. The WEB Debit Account Validation Rule now takes effect March 19, 2021, rather than Jan. 1, 2020. The rule was originally approved by Nacha members in November 2018. The Nacha Board of Directors approved the extension in effective date to allow for additional time, education and guidance to be provided to the industry. 
 

Differentiating Unauthorized Return Reasons

This rule better differentiates among types of unauthorized return reasons for consumer debits. This differentiation will give ODFIs and their Originators clearer and better information when a customer claims that an error occurred with an authorized payment, as opposed to when a customer claims there was no authorization for a payment. ODFIs and their Originators should be able to react differently to claims of errors, and potentially could avoid taking more significant action with respect to such claims.

Differentiating Unauthorized Return Reasons

Return for Questionable Transaction

ACH Rules Compliance Audit Requirements

This rule changes the structure of the audit requirement within the Rules, but does not change the requirement to conduct a Rules compliance audit annually.  

Same Day ACH: Moving Payments Faster (Phase 3)

New capabilities of Same Day ACH become effective over phases to allow financial institutions and businesses to acclimate to a faster processing environment, as well as to ease the implementation effort. Beginning March 16, 2018, RDFIs will be mandated to make funds available from same day ACH credits (such as payroll Direct Deposits) to their depositors by 5:00 PM at the RDFI’s local time. 

The Rule enables the option for same-day ACH payments through additional ACH Network functionality, without affecting previously available ACH schedules and capabilities:
