What Are the Nacha 2026 Rule Changes?
The new rules require all non-consumer ACH Originators—whether you process hundreds or millions of ACH credit payments annually—to implement risk-based processes for fraud detection and bank account ownership verification.
The changes roll out in two phases:
- Phase 1 (March 20, 2026): Applies to Originators and Third Parties processing more than 6 million transactions per year.
- Phase 2 (June 19, 2026): Applies to all other ACH credit Originators, regardless of volume.
The key mandate:
Originators must verify the ownership of the recipient’s bank account using validated data sources before sending funds.
These Nacha 2026 rule changes aim to prevent the most common and costly forms of ACH credit fraud, including vendor impersonation and business email compromise (BEC).
Why Nacha Is Making This Move
ACH credit fraud has surged in recent years, driven by increasingly sophisticated social engineering tactics. Criminals now impersonate vendors, hijack legitimate email accounts, and request banking changes that reroute payments—often undetected until it’s too late.
According to the 2025 AFP Payments Fraud and Control Survey:
- 79% of organizations experienced an attempted or successful payments fraud attack.
- Business email compromise (BEC) accounted for over 60% of those attacks.
- The average loss per fraud incident is projected to exceed $300,000 by 2026.
Nacha’s Risk Management Advisory Group (RMAG) flagged vendor banking updates—often handled through spreadsheets, emails, or phone calls—as a critical risk vector. The 2026 rule changes are a direct response to these vulnerabilities.
What Nacha 2026 Rule Changes Mean for You
If your organization originates ACH credits, these new rules apply to you. You’ll be expected to:
- Implement a documented, risk-based process for verifying bank account ownership.
- Review and update that process annually.
- Maintain a detailed, auditable record of compliance.
And here’s the kicker: manual processes are no longer enough.
Policies aren’t procedures—and Nacha’s own research found that while 58% of organizations say they have a policy, only 15% have documented, reviewed, and tested procedures that meet the compliance bar.
The High Stakes of Non-Compliance With Nacha 2026 Rule Changes
Failure to comply with the Nacha 2026 rule changes doesn’t just mean regulatory risk. It puts your organization at real financial and reputational risk.
Without verified bank account ownership, a single fraudulent update could lead to a massive, irreversible loss. ACH credits can’t be recalled, and reversals are typically not allowed. Once the money is gone, it’s gone.
In addition:
- Your bank may audit your compliance or even require remediation.
- You may lose the confidence of internal stakeholders or external partners.
- You’ll struggle to defend your practices in the face of fraud-related incidents or legal action.
Why Manual Processes Won’t Cut It
Many organizations still rely on outdated, manual approaches to vendor onboarding and bank account verification:
- Phone calls
- Spreadsheets
- Email approvals
- “Policies” that no one’s reviewed in years
But with thousands of “vendoring events” (new vendors, updates, changes) happening annually, this kind of manual oversight is not only inefficient—it’s unsustainable and risky.
Every vendoring event is a potential entry point for fraud.

Your Roadmap to 2026 Compliance
Here’s how to prepare:
1. Conduct a Risk Assessment
Audit your current processes. Where are the gaps? Are vendor bank account changes verified with a validated source? Who is responsible for what?
2. Document Your Procedures
Move beyond a “policy” and create a formal, role-based procedure that outlines exactly how bank account ownership is verified—before any payment is sent.
3. Test and Update Regularly
Nacha requires that your verification process be reviewed and tested at least annually. Consider quarterly check-ins to keep up with evolving threats.
4. Automate What You Can
Use technology to eliminate manual steps. Vendor identity platforms like PaymentWorks provide real-time verification, audit trails, and fraud protection—at scale.
