Constitution of the State of Georgia Art. III, § 9, ¶ II

(a) The Governor shall submit to the General Assembly within five days after its convening in regular session each year a budget message and a budget report, accompanied by a draft of a general appropriations bill, in such form and manner as may be prescribed by statute, which shall provide for the appropriation of the funds necessary to operate all the various departments and agencies and to meet the current expenses of the state for the next fiscal year.

(b) The General Assembly shall annually appropriate those state and federal funds necessary to operate all the various departments and agencies. To the extent that federal funds received by the state for any program, project, activity, purpose, or expenditure are changed by federal authority or exceed the amount or amounts appropriated in the general appropriations Act or supplementary appropriation Act or Acts, or are not anticipated, such excess, changed or unanticipated federal funds are hereby continually appropriated for the purposes authorized and directed by the federal government in making the grant. In those instances where the conditions under which the federal funds have been made available do not provide otherwise, federal funds shall first be used to replace state funds that were appropriated to supplant federal funds in the same state fiscal year. The fiscal year of the state shall commence on the first day of July of each year and terminate on the thirtieth of June following.

(c) The General Assembly shall by general law provide for the regulation and management of the finance and fiscal administration of the state.
