Mississippi Code Title 19. Counties and County Officers § 19-11-19

(1) When it shall appear to the board of supervisors that collection of anticipated revenues from taxation and/or other sources for any fund or funds of any county will be more than the amounts estimated, or when it appears that such revenues will be less than estimated, the board of supervisors may revise the budget of expenses at any regular meeting during the fiscal year by increasing or decreasing the items of said budget in proportion to the increase or decrease in the anticipated revenue collections and/or other sources of funds. When it shall appear to the board of supervisors that some item of the budget is in excess of the requirements of said item, and that the amount budgeted to such item will not be needed during the fiscal year, the board may, at any regular meeting, transfer funds to and from items within the budget when and where needed, but no such transfer shall be made from fund to fund, or from item to item, which will result in the expenditure of any money for a purpose different from that for which the tax was levied. However, revisions as herein authorized shall not be deemed to permit any expenditures in excess of the various items of the budget as then approved, and any expenditures made in excess of the budget as then approved shall be invalid, and subsequent revision shall not validate such expenditures. The revisions made in the budget, from time to time, shall be spread upon the official minutes of the board at the meeting at which any such revision is made.

(2) The reductions authorized under this section shall not exceed the reduction restrictions under Section 19-11-11.
