Tex. Local Government Code § 111.063

(a) The budget officer shall itemize the budget to allow as clear a comparison as practicable between expenditures included in the proposed budget and actual or estimated expenditures for the same or similar purposes that were made for the preceding fiscal year. The budget must show with reasonable accuracy each of the projects for which an appropriation is established in the budget and the estimated amount of money carried in the budget for each project.

(b) The budget officer shall obtain from the county auditor any information necessary to prepare a complete financial statement for inclusion in the budget. The financial statement must show:

(1) the outstanding obligations of the county;

(2) the cash on hand to the credit of each fund of the county government;

(3) funds received from all sources during the preceding fiscal year;

(4) the funds and revenue estimated by the auditor to be received from all sources during the preceding fiscal year;

(5) the funds and revenue estimated by the auditor to be received during the ensuing year; and

(6) a statement of all accounts and contracts on which sums are due to or owed by the county as of the last day of the preceding fiscal year, except for taxes and court costs.

(c) If actual amounts for the information described by Subsection (b)(1), (b)(2), (b)(3), or (b)(6) are not available at the time the budget officer prepares the financial statement, the budget officer may use in the preparation of the statement estimates of that information made by the county auditor.

(d) Subsection (c) does not prevent the commissioners court from adopting a budget before the beginning of the fiscal year for which the budget is prepared.
