How the Rules are Made

Designing Rules for a Secure, High-Quality ACH Network

Be Part of the Rulemaking Process

Overview Icon

The Rulemaking Process provides a disciplined, industry-inclusive method for developing new Rules. The NACHA Operating Rules are at NACHA’s heart: without them, we would not have a defined foundation for the exchange of ACH payments.

The rulemaking process is the brains of the operation, logical and well-defined in its inclusive approach. ACH Network users are involved throughout the creation of each new Rule, and we ensure that proposed ACH amendments support the evolving needs of those making and receiving payments.

Learn How the Rules Are Made

NACHA’s rulemaking process includes feedback and participation from all ACH Network participants. Members and key parties can present proposed Rule changes to NACHA, and individuals or organizations can leverage the Business Idea Submission process to share new Rules ideas with NACHA.

Who Can Submit an Idea?

Idea generation sources include the following organizations/bodies:

  • NACHA Board of Directors
  • Direct Member Organizations and the Payments Innovation Alliance
  • Standing Committees, Advisory Groups and Task Forces (e.g., Rules & Operations Committee, Risk Management Advisory Group, Direct Member Task Force)
  • ACH Operators
  • Government Agencies (e.g., Treasury/Financial Management Service, Federal Reserve Board, Social Security Administration)
  • NACHA Staff 

Other organizations or parties that wish to have a business idea considered should work with one of these sources.

How the Rulemaking Process Works


  • An eligible party presents a Rule proposal to NACHA.
  • The proposal is then shared with NACHA’s Rules and Operations Committee, which consists of industry representatives from ACH Network users, to evaluate the proposed change.  
  • The Rules and Operations Committee may accept the proposal into the Rulemaking Process, reject the proposal, or request more information.
  • The Rules and Operations Committee develops a Request For Comment (RFC) or Request for Information (RFI). An RFC is created if there is enough information pertaining to the proposed Rule change; an RFI is issued when more information is needed..
  • Staff then draft the Rules language to support the proposal. The Committee obtains expert input from the ACH Operators, the Software Information Exchange (a group of software and service providers), the Corporate Information Interface and legal counsel. 


  • The Rules and Operations Committee approves the issuance of an RFC.
  • NACHA distributes the RFC via email communications to the industry at large, requesting feedback from financial institutions, businesses, service providers, government entities, consumer groups and others. In addition, NACHA posts the RFC to its website to encourage broad industry response.
  • The RFC/RFI is open for a set duration of time, generally 45 days, although the time allotted may be longer or shorter depending on the proposal’s complexity.


  • Staff summarize the RFC responses and share the feedback with the Rules and Operations Committee.
  • If the responses suggest moving forward, the Rules and Operations Committee will develop a final proposal, with additional expert input.
  • NACHA shares a summary of comments with the industry. 


  • The Rules and Operations Committee makes a final decision that a rule proposal should be balloted. 
  • Ballots are distributed to the Voting Membership, and Members vote on the proposed Rule.
  • NACHA communicates the results of the vote to NACHA Direct Members.
  • If the ballot is approved, the NACHA Operating Rules are amended to incorporate it by the implementation date established in the ballot, and a Rules Supplement is formally published to all subscribers.
  • If the ballot is not approved, NACHA evaluates the feedback received and determines what, if any, steps are necessary for addressing the topic raised in the ballot. If additional steps are necessary, NACHA reconvenes the rulemaking process.

Voting Methods

The Rules can be amended through either a NACHA member vote or weighted vote. The member vote functions like the Senate: each member gets one vote, regardless of the organization’s size. The weighted vote, on the other hand, is akin to the House of Representatives: each member’s vote is weighted in accordance with that organization’s ACH volume and the number of financial institutions it represents.

A Rule can pass in one of two ways:

The "approve" vote exceeds a three-quarters member vote
The "approve" vote exceeds a two-thirds weighted vote

On the other hand, if two-thirds of the members comprising a member category– including Direct Financial Institutions and Regional Payments Associations– vote against a proposed Rule, that Rule would not pass.
