ACH transactions, whether debit or credit, typically settle within 1–3 business days. Some payments may settle the same day if originated as Same Day ACH.

Federal Reserve processing windows and operating hours

ACH payments settle only on bank business days. No settlement happens on weekends or Federal holidays.

An ACH Credit occurs when an originator instructs their bank (

) to push funds to a receiver’s account at another financial institution (

RDFIs must make funds from credit entries available to receivers by the settlement date.

Certain requirements apply for standard ACH credits:

The credit must be delivered to the RDFI by the ACH Operator no earlier than two banking days prior to settlement date

It must be posted (or memo-posted) by opening of business on the settlement date.

 on the Settlement Date if received by 5:00 p.m. the prior business day.

These requirements apply for all SEC codes.

For Same Day credits, these requirements apply:

The credit must be delivered to the RDFI on the settlement date.

Funds become available according to these deadlines (depending on when sent):

First Same Day window → by 1:30 p.m. local time

Second Same Day window → by 5:00 p.m. local time

Third Same Day window → posting required on the settlement date. Withdrawal availability may be deferred until the next day.

Exception: If the RDFI reasonably suspects the credit is unauthorized, it may delay availability subject to legal requirements, but must promptly notify the ODFI.

An ACH Debit occurs when an Originator instructs their bank (ODFI) to pull funds from a Receiver’s account at another financial institution (RDFI).

Certain requirements apply for standard ACH debits:

Credits are made available to RDFIs no earlier than one banking day before settlement date.

RDFIs may not post debit entries prior to the settlement date.

For Same Day debits, these requirements apply:

The debit must be delivered to the RDFI on the settlement date.

 Settle on the originated date, if submitted before the ACH Operator deadline (FedACH cut-off ~4:45 p.m. ET).

Only eligible for domestic payments (no international transactions)

ACH transactions may still be returned for reasons such as insufficient funds or unauthorized activity. Consumer unauthorized debits can be returned for up to 60 calendar days under Nacha rules. Finality of settlement is therefore subject to Nacha return windows.

ACH transactions settle in 1–3 business days, or same day if Same Day ACH. Credits and debits follow Fed and Nacha rules, with a $1M Same Day limit and domestic-only for Same Day.
