Okla. Stat. tit. 11, § 11-17-206: Requirements and contents of budget

A. The municipal budget shall present a complete financial plan

for the municipality and shall present information necessary and

proper to disclose the financial position and condition of the

municipality and the revenues and expenditures thereof, both past

and anticipated.

B. Unless the budget is prepared in accordance with Sections 4

and 5 of this act, the budget shall be prepared by fund and

department and shall contain the following contents:

1. The budget shall contain a budget summary;

2. It shall also be accompanied by a budget message which shall

explain the budget and describe its important features;

3. The budget format shall be as provided by the governing body

in consultation with the chief executive officer; and

4. It shall contain at least the following in tabular form for

each fund, itemized by department and account within each fund:

a. actual revenues and expenditures for the immediate

prior fiscal year,

b. revenues and expenditures for the current fiscal year

as shown by the budget for the current year as adopted

or amended, and

c. estimates of revenues and expenditures for the budget

year.

C. The estimate of revenues for any budget year shall include

probable income by source which the municipality is legally empowered

to collect or receive at the time the budget is adopted. The

estimate shall be based on a review and analysis of past and

anticipated revenues of the municipality. Any portion of the budget

of revenues to be derived from ad valorem property taxation shall not

exceed the amount of tax which is available for appropriation, as

finally determined by the county excise board, or which can or must

be raised as required by law. The budget of expenditures for each

fund shall not exceed the estimated revenues for each fund. No more

than ten percent (10%) of the total budget for any fund may be

budgeted for miscellaneous purposes. Included in the budget of

revenues or expenditures for any fund may be amounts transferred from

or to another fund. Any such interfund transfer must be shown as a

disbursement from the one fund and as a receipt to the other fund.

D. Encumbrances for funds whose sole purpose is to account for

grants and capital projects and/or any unexpended appropriation

balances may be considered nonfiscal and excluded from the budget by

the governing body, but shall be reappropriated to the same funds,

accounts and for the same purposes for the successive fiscal year,

unless the grant, project or purpose is designated or declared closed

or completed by the governing body.
