The Automated Clearing House (ACH) network is an essential part of how businesses move money every day, whether paying employees, collecting customer payments, or managing recurring billing. To strengthen fraud prevention and improve transaction transparency, NACHA is introducing several important rule updates beginning in 2026. These changes will affect all non-consumer ACH originators and third-party senders, and it’s important to understand how they may impact your business.
Why These Changes Are Happening
Fraud activity has continued to evolve. NACHA’s new rules aim to ensure organizations implement risk-based monitoring, verify unusual activity, and strengthen internal controls around ACH authorizations and changes to payment instructions.
Key Changes Coming in 2026
- Risk-Based Fraud Monitoring (All Originators) – Beginning in 2026, organizations are required to use proactive, risk-based processes to identify and prevent fraudulent outgoing ACH entries. This includes validating transactions that appear unusual based on historical behavior.
- Standardized Company Entry Descriptions – Effective March 20, 2026, two new standardized descriptions must be used for specific ACH transactions:
- PAYROLL — Required for all ACH credit entries used to pay wages, salaries, or similar compensation.
- PURCHASE — Required for all e-commerce consumer debit purchases, including recurring purchases initially authorized online.
- These changes help improve clarity and consistency across payment types, making suspicious activity easier to detect.
- Compliance Timeline – NACHA is phasing in compliance to give organizations time to adjust:
- Phase 1 — March 20, 2026: Applies to organizations and third parties that originated 6 million+ ACH entries in 2023.
- Phase 2 — June 19, 2026: Applies to all other non-consumer originators and third-party senders.
What Organizations Need to Do Now
To prepare for the new rules, NACHA recommends:
- Strengthening authorization practices and ensuring documentation is complete and accessible.
- Monitoring for unusual authorization activity that may signal fraud.
- Closely verifying changes to account details, since fraudulent payment instruction changes are a common attack vector.
Why This Matters
These updates aren’t just regulatory, they’re an opportunity to improve security, reduce fraud risk, and increase customer trust. By adopting best practices early, your business can avoid disruptions and ensure smooth payment operations going into 2026.
