2026 NACHA rules require ACH compliance updates, standardized descriptions, and fraud monitoring policies for organizations to reduce risk and maintain access

The Automated Clearing House (ACH) Network is the backbone of U.S. payments, processing tens of billions of transactions each year.  As ACH usage grows, so do fraud risks.   

In response, Nacha (National Automated Clearing House Association), which governs the ACH network, has announced the most significant ACH rule changes in years.  These updates are designed to reduce successful fraud attempts and improve fund recovery after fraud occurs. 

These changes are not bank specific.  They apply to all ACH “Originators” and represent a shift from “best practice” to a formal compliance requirement. 

Standardized ACH Descriptions (Effective March 20, 2026)

Beginning March 20, 2026, NACHA requires standardized Company Entry Descriptions to provide higher visibility for specific transaction types. 

Key Changes 

“PAYROLL” for 1099 vendors 

• The entry description PAYROLL must be used with the PPD entry class code for payments made to all 1099 vendors. 

• This rule applies to salaries, wages, or similar employee compensation paid via ACH.  Most employee payroll is processed through third-party payroll providers and is already compliant.  

• This does not apply to ACH payments for employee expense reimbursements. 

“PURCHASE” for E-commerce Transactions 

• Required for online purchases of goods. 

• Generally, not applicable to GovCon Synergies (GCS) clients, who typically use corporate credit cards or direct debit transactions. 

GovCon Synergies has identified the following steps to ensure 1099 Nacha file payments meet the new Nacha standard: 

• Clear Nomenclature: Use a clear “1099” prefix in your Organization Code (e.g., “1099_JSMITH”) for easy identification for 1099 vendors 

• Create a separate 1099 Nacha Export Template 

• Copy your existing vendor NACHA export file template  

• Update the Entry Class Code from CCD to PPD  

• Enter PAYROLL in the Entry Description field in the Group Header Record 

ACH Fraud Monitoring Requirements (Effective June 22, 2026)

Starting June 22, 2026, all ACH Originators must maintain a documented ACH fraud monitoring process and procedure. Your bank may request this policy at any time as a condition of continuing ACH services.   

For government contractors, these requirements align closely internal control and audit expectations. 

GCS Recommended Fraud Mitigations 

GovCon Synergies recommends including the following elements in your documented procedures:  

• Validation Procedures: Document how recipient banking information is obtained, verified, and updated (e.g. voided check, bank documentation, prenotes). 

• Independent Authentication: Verify all payment detail changes using a secondary communication method.  For example, email change requests should be confirmed via a callback to a phone number already on file. 

• Dual Controls: Require separate individuals to initiate and approve ACH files and vendor setups within online banking platforms. 

• Annual Review: Document that ACH fraud monitoring procedures are reviewed at least annually to address evolving risks. 

• Enable Alerts:   Gain visibility on large, unusual, or high-risk transactions. 

• Regular Reconciliation: Confirm transactions weekly at a minimum to flag abnormal activity.  

• Accountability: Identify a designated point of contact for investigating discrepancies and working with the bank in a timely manner.  Regularly review user access and remove permissions when roles change or employees leave. 

• MFA and Alerts: Utilize Multi-factor Authentication (MFA) for all ACH releases and approvals. 

Executive Action Plan 

To meet the 2026 NACHA mandates, financial leaders should take action now: 

1. Streamline Your 1099 Processes: Identify all 1099 vendors in Unanet and prepare a compliant 1099 vendor Nacha export template. 

1. Develop and maintain a written ACH Fraud Monitoring Policy: This is no longer optional, failure to do so could result in losing the ACH privileges with your bank. 

1. Build in Accountability: Schedule annual reviews to keep your fraud prevention procedures current and effective amid evolving risks.
