Nacha Compliance
Trustmi helps you meet Nacha's new ACH fraud monitoring requirements with continuous risk monitoring, account verification, and audit-ready controls.
Risk Assessment
Nacha named the fraud.
Now you’re required to stop It.
For years, companies have lost money to payment requests that looked legitimate, were approved internally, and still turned out to be fraud.
Nacha now calls this false pretenses: payments induced through deception.
Under the 2026 rule changes, organizations are expected to detect and prevent it. Failure can lead to fines, enforcement actions, and loss of ACH privileges.
Why Current Controls Fall Short of What Nacha Requires
For many organizations, bank account validation is the last line of defense. But false pretenses use accounts that can pass those checks.
In reality, an account validation just confirms an account is real, active, and able to receive funds—not that the payment should go there. In fact, 90% of bank accounts used in B2B payment fraud are bank-approved accounts that can pass standard validation checks.
Many fraud controls are designed to catch risk at the moment a payment is created or released. But false pretenses usually happen earlier, before any payment file exists.
Most B2B payment fraud attacks start in email, and 92% involve the impersonation of executives or vendors. By the time the ACH entry is sent, the request may already be approved in workflow and queued for payment.
AP teams often rely on verbal confirmations, email threads, and spreadsheet logs to verify payment changes and document approvals.
This manual and fragmented process makes it difficult to satisfy Nacha’s new requirement that procedures be reasonably intended to identify fraudulent entries.

FAQs
Nacha’s 2026 amendments require all non-consumer Originators, Third-Party Senders, and Third-Party Service Providers to establish documented, risk-based processes for identifying ACH entries that are unauthorized or authorized under False Pretenses. Phase 1 took effect March 20, 2026 for organizations with 6 million or more ACH entries. Phase 2 expands this requirement to all remaining participants effective June 22, 2026.
The previous rules required a vague “commercially reasonable fraudulent transaction detection system” for a limited subset of debit transactions. And this was primarily WEB debits. The 2026 rules extend requirements to ACH credits. It also introduces False Pretenses as a defined fraud category that organizations must actively monitor for.
Account validation does not detect whether a payment request was genuine. False Pretenses fraud specifically targets the space between those two things. An attacker who has compromised a vendor’s email, changed their banking details, and induced an authorized payment has passed every validation check.
No, Nacha compliance doesn’t guarantee complete protection from payment fraud. That’s because compliance is a baseline set of rules, not a security solution. Meeting Nacha’s requirements ensures you follow standardized, risk-based processes, but those checks can still miss sophisticated, socially engineered attacks.
Trustmi goes beyond the checkbox, using Behavioral AI to detect and stop hidden fraud across your entire payment ecosystem before it’s submitted to the ACH network.
Trustmi works alongside existing controls including ACH blocks, filters, and bank-side validation tools. Those controls address unauthorized external debits. Trustmi also addresses the fraud that passes those controls cleanly because it travels inside the authorized payment process.
Nacha compliance under the 2026 rules is not solely a finance or IT concern. It requires coordination across accounts payable, treasury, compliance, and information security. Trustmi connects all of these functions through a single platform, giving each team the visibility they need without requiring manual coordination across systems.
Deploying Trustmi’s Nacha compliance solution is fast, because it connects to your existing systems through ready-made integrations for major ERP platforms, business applications, and payment systems. It plugs in through secure APIs with no changes to your established finance workflows, so your team keeps processing ACH transactions exactly as they do today while Trustmi monitors for fraud continuously in the background.
