The county commissioners must identify in the itemized estimated budget all revenue sources, including balances in reserve accounts and other such funds, used in arriving at their budget estimates.  

2.  Budget review process.  The budget committee shall review the itemized estimated budget prepared by the county commissioners, together with any supplementary material prepared by each county department or provided by any independent board or institution or another governmental agency. The budget committee may use the surplus balance in any reserve account retained by the county after the purposes for which the account was created are accomplished or abandoned to reduce the county tax levy in the same manner as county commissioners are authorized to do under section 921. The budget committee shall prepare a proposed budget and may increase, decrease or alter the itemized estimated budget if:  

3.  Public hearing.  The budget committee shall hold a public hearing in the county on its proposed budget before the end of the county's fiscal year and before the final adoption of the budget.

4.  Finality of budget.  After the public hearing is completed, the budget committee shall adopt a final budget and transmit that budget to the county commissioners. The county commissioners may not further increase, decrease, alter or revise the budget as adopted by the budget committee, except by unanimous vote of the county commissioners. If the adopted budget is changed by the county commissioners, the budget committee may reject that change by a 2/3 vote of its membership. Those actions are final and are not subject to further action by either the county commissioners or the budget committee.  

5.  Assessment of taxes.  The budget as adopted and changed under subsection 4 is the final authorization for the assessment of county taxes.
