35 Miss. Code. R. 1-04-208
An ACH Credit payment must be transferred to the State of Mississippi's bank account by the due date of the taxes. A taxpayer must ensure that the financial institution originating the transaction does so in sufficient time for the payment to be deposited as immediately available funds to the State Treasury on or before the appropriate due date of payment. If the due date falls on a holiday or weekend, payment must be initiated to be received by the State of Mississippi's bank on the first business day after the due date.
