IMPORTANT UPCOMING CHANGES IN 2026
 

Fraud Monitoring Requirements – effective June 20, 2026.

All non-consumer ACH originators must establish and implement risk-based processes and procedures reasonably intended to identify ACH entries initiated due to fraud. This rule is intended to migrate fraud in ACH transactions, specially targeting Unauthorized Entries (Transactions initiated without the account holder’s permission) and Entries Authorized under Falso Pretenses (Payments resulting from deception, such as email compromise, vendor impression or payroll impression).

 

This rule requires that your business establishes and maintains a proactive risk-based approach:

 

  • Establish and Implement Risk Based Procedures : You must define and apply processes and procedures that are reasonably intended to identify outgoing ACH entries that may be unauthorized or initiated under false pretenses.
  • These processes and procedures must be reviewed and, if necessary, updated at least annually to address evolving fraud risks.
  • You must conduct a risk assessment to identify high-risk vs. low-risk transactions and apply appropriate monitoring measures.

As a reminder, Nacha standardized the “Company Entry Description” field for two specific types of transactions, which was effective March 20, 2026.

 

  • PAYROLL: For all credit entries (PPD) used to pay wages, salaries, bonuses, commissions, or other similar compensation. 
  • PURCHASE: For all e-commerce debit entries authorized by a consumer for the online purchase of goods. 

 

We would like to take this opportunity to remind you about important security practices that can help you protect your accounts along with the reminder to never update vendor account information received via email without validating the information directly with the vendor using the phone number you have on file.

 

For best practices, please visit the Federal Communications Commission's website. 

 

We appreciate your business and look forward to continuing to serve your financial needs in the future. If you have any questions, please do not hesitate to contact us.
