ACH timing is straightforward, but a payroll that is funded late or initiated late will not land on pay day no matter how the rest of the system performs. Understanding the basic settlement window prevents most direct-deposit surprises.
The standard schedule
A standard ACH credit settles in one to two business days. For a payroll with a Friday pay date, the system typically initiates the deposit on Wednesday or Thursday, the funds debit from the employer's funding account on the trigger date, and the credit lands in the employee's account by Friday morning.
Weekends and federal banking holidays do not count as business days. A payroll with a pay date that lands on a holiday settles on the next business day at the receiving bank, even though the system initiates on the normal schedule.
Same-day ACH
Same-day ACH is a separate NACHA window that settles within hours rather than one to two days. It costs more per transaction and has cutoff times that are earlier in the day than standard ACH. For a tight pay date where the standard schedule would miss, same-day ACH closes the gap.
For most regular payrolls, same-day is not used — the cost is not justified when standard timing reaches the employee on time. Off-cycle payrolls (a correction, a termination payout, an emergency bonus) are the more common case for same-day.
Funding the payroll
For the deposit to land on the pay date, funds need to be available in the employer's funding account when the debit initiates — generally one to two business days before pay date. If the funding account is short on the trigger date, the debit fails and the payroll cannot settle.
The funding deadline for each payroll is shown on the payroll-run review screen. Available balance is what counts, not statement balance — large incoming deposits that have not yet cleared do not contribute to available funds.
Reversing or returning a deposit
A direct deposit that has already settled cannot be canceled like a card transaction. If a payroll is overpaid or sent to a wrong account, the recovery is either a reversal request (permitted only in narrow cases — wrong amount, wrong account, duplicate — and only within a few business days of the original settlement), or a return from the receiving bank if the account rejected the credit. NACHA defines the rules for both.
The most common return reasons each have their own code. The separate article on return codes covers what each one means and what to do about it.
