Nacha is requiring the standardized use of specific transaction descriptions effective March 20, 2026. ACH originators are required to comply with Nacha operating rules.

  • ACH credits related to wages must use the description "Payroll"
  • ACH debits related to consumer e-commerce purchases must use the description "Purchase"

This rule applies to all ACH originators initiating these types of transactions and is mandatory by March 20, 2026. We recommend beginning to review and update your templates as soon as possible to ensure a smooth transition. Abbreviations to these descriptions are not allowed.

What you need to do:

  • When creating new ACH files, populate the Entry Description as outline

  • For Existing ACH templates, update your payroll files to include "Payroll" in the Entry Description field and "Purchase" for all relevant consumer e-commerce debits

  • If you use a third-party payroll or accounting software, reach out to them to understand how to implement this change
