ACH Annual Communication 2026

Annually, the National Automated Clearing House Association (NACHA), the rule-making body for the ACH network, makes edits and updates to the Operating Rules. As a courtesy to our customers and to assist in rules compliance, we communicate those updates as well as provide a few reminders regarding ACH processing through Nicolet National Bank.
