Electronic Funds Transfer (EFT) Pay Date
The EFT pay date is determined by the Pay Processing Group that your agency is assigned to in FPPS. The pay date should be when funds are deposited into employees’ bank accounts. Below is a table that reflects the EFT pay date by Pay Processing Group. Please note that the “official pay date” for all agencies is the second Tuesday following the end of the pay period. If you are unsure which Pay Processing Group your agency is in, you can review the Pay Processing Group Report.
Pay Processing Groups | EFT Pay Date | Official Pay Date |
|---|---|---|
Databases 1 (241) and | Same as Official Pay Date | Second Tuesday following the end of the Pay Period |
Databases 2 (242) and | Normally the first Friday following the end of the Pay Period | Second Tuesday following the end of the Pay Period |
As a reminder, the Department of the Treasury begins processing payment files two days prior to the EFT pay date and some financial institutions may advance funds to accounts prior to the official EFT pay date. Please advise your employees that IBC is unable to address any deposits that are made on a date prior to the established EFT pay date.
