Mississippi Code Title 19. Counties and County Officers § 19-11-25

All appropriations of funds made under the provisions of a budget for a fiscal year shall lapse at the end of such year, and all books shall close September 30. All disbursements and appropriations made on and after October 1, other than appropriations for incompleted improvements in process of construction, shall be charged against the current budget, and all funds actually received on and after October 1 shall be credited to the current budget. However, when the delay in presentation of any such claim is caused by a wilful act of a member of the board of supervisors or other official of the county, such supervisor or other official shall be liable on his official bond, to the claimant thereof, for the amount of same. In the administration of the Homestead Exemption Law of 1946, however, the time shall be extended to October 20 following the close of the fiscal year, for both the payment of claims and the accounting of revenue, belonging to and/or accruing to the immediately prior fiscal year.
