New capabilities of Same Day ACH become effective over phases to allow financial institutions and businesses to acclimate to a faster processing environment, as well as to ease the implementation effort. Beginning September 15, 2017, Same Day ACH will be available for debit entries, enabling the same-day processing of virtually any ACH payment.
The Rule enables the option for same-day ACH payments through additional ACH Network functionality, without affecting previously available ACH schedules and capabilities:
Originating financial institutions (ODFIs) are able to submit files of same-day ACH payments through two additional clearing windows provided by the ACH Operators (Note: The actual ACH Operator schedules are not determined by the NACHA Operating Rules.):
A morning submission deadline at 10:30 AM ET, with settlement occurring at 1:00 PM.
An afternoon submission deadline at 2:45 PM ET, with settlement occurring at 5:00 PM.
Virtually all types of ACH payments, including both credits and debits, are eligible for same-day processing. Only international transactions (IATs) and high-value transactions above $25,000 are not eligible. Eligible transactions account for approximately 99 percent of current ACH Network volume.
All RDFIs are required to receive same-day ACH payments, thereby giving ODFIs and Originators the certainty of being able to send same-day ACH payments to accounts at all RDFIs.
