Miss. Code § 27-104-23
The State Auditor and from and after July 1, 1986, the State Fiscal Officer, shall maintain his records and accounts in such a manner that, insofar as funds paid from the State Treasury are concerned, only the amounts approved by the State Fiscal Officer or authorized in the agency appropriation bill shall be available for expenditure during any allotment period by the state agency entitled thereto. The State Auditor, or the State Fiscal Officer, as the case may be, shall be liable on his official bond for any failure on his part to fully comply with the provisions of this section.
It shall be the duty of any officer or employee of any state agency who is clothed with the authority to make purchases or obligations or incur expenses to keep records of such purchases, obligations, or expenses incurred by him, and such purchases, obligations, or expenses incurred shall be entered upon the records the day they are made. No such purchases, obligations, or expenses shall be incurred after June 30 of the then fiscal year which would encumber funds appropriated for the fiscal year just ending. It shall be the duty of each agency coming within the purview of Sections 27-103-101 through 27-103-139 and 27-104-1 through 27-104-29 to submit, on or before July 15, a statement on a form prepared and furnished by the State Fiscal Officer, showing a detailed list of all encumbrances outstanding as of the close of the preceding fiscal year, together with purchase order numbers and such other information as the State Fiscal Officer may require.
