Miss. Code § 7-7-59
A reasonable petty cash fund shall be allowed each state department, institution, board, commission or other agency if, in the judgment of the State Fiscal Officer, such is necessary for the proper operation of the fiscal affairs thereof. The amount of such petty cash fund shall be fixed by the State Fiscal Officer in each case, but these funds shall be reimbursed only upon vouchers audited by the State Fiscal Officer. It shall not be lawful for any petty cash fund to be used for cashing checks or otherwise advancing funds to any officer or employee of any state department or agency.
The State Fiscal Officer may by regulation provide for the establishment of commercial bank accounts by any state agency, which shall serve as the depository for self-generated funds and custodial funds not required by law to be deposited in the State Treasury. The regulations may provide for such accounts to be used for disbursements not required to be made by warrants on the State Treasury. Each such account established shall have a maximum balance to be fixed by the State Fiscal Officer. All such accounts shall bear interest. For self-generated funds, the interest shall be deposited in the General Fund and for custodial funds, the interest shall be deposited in the custodial bank account. The State Auditor shall test for compliance with this section in any postaudit, and may, after notice and hearing, levy a civil penalty not to exceed One Thousand Dollars ($1,000.00) for any violation hereof. The auditor shall annually report all violations of this section to the Governor and the Legislature.
