This page provides information about biennial budgeting for cities, towns, and counties in Washington State, including relevant statutes and a list of jurisdictions that use biennial budgets.
Most cities, towns, and counties in Washington operate under an annual budget, but some budget on a biennial (two-year) basis.
Biennial Budgeting for Cities and Towns
Any cities and towns may begin budgeting on a biennial basis if desired (see Ch. 35A.34 RCW for code cities and Ch. 35.34 RCW for all other cities and towns).
By statute, the biennial fiscal year must start on January 1 of an odd-numbered year and end on December 31 of the following even-numbered year. To begin budgeting on a biennial basis, a city or town must pass an ordinance to that effect no later than June 30 of the preceding even-numbered year, six months before the beginning of the fiscal biennium.
In addition, the city or town must review and modify the budget halfway through the biennium.
Biennial Budgeting for Counties
Any county may adopt a biennial budget (see RCW 36.40.250). Unlike cities, counties may start the biennium in any fiscal year. The county statute also gives no indication of when the ordinance or resolution providing for a biennial budget must be passed. Practically speaking, it probably needs to be done by the end of June so that departments can prepare the estimates that are due to the auditor in August.
The county must review and modify the budget halfway through the biennium.
