Mo. Rev. Stat. § 33.220

33.220. Each department to submit estimates of money requirements. — On or before October first in each year preceding the annual session of the general assembly, each department shall submit to the budget director estimates of its requirements for appropriations for the year commencing on the first day of July next. Such estimates shall be on forms prescribed by the budget director. Such forms shall provide, as nearly as practicable, for a uniform presentation and classification of estimates. Blank copies of forms on which estimates shall be submitted shall be sent by the budget director to each department on or before September first of each such year. Estimates shall be submitted for each subdepartment, division or bureau of each department down to the smallest organization unit and for the department as a whole. Separate estimates shall be submitted for each fiscal year. Separate estimates shall also be submitted for each fund from which requested appropriations are to be made, and on another form such estimates shall be consolidated to show total estimates from all funds. All such estimates shall be so subdivided and classified as to show all estimated expenditures for all purposes in such detail as may be required by the budget director. All estimates for federal funds shall include the amount of federal funds required, the federal program number of each federally funded program the department plans to administer, the amount, if any, of state funds required for each program, a description adequate to give the members of the legislature knowledge of the objectives of each program and such other information as may be required by the budget director. Estimates shall show separately the requirements for ordinary expenditures for operation and maintenance, extraordinary expenditures for operation and maintenance, and capital expenditures. Each estimate for extraordinary expenditure and for capital expenditure shall be explained in detail. The estimates shall be accompanied by such reports, data or other explanatory matter as the department may care to submit.
