Biennial Budgeting
This page provides information about biennial budgeting for cities, counties, and special purpose districts in Washington State, including relevant statutes, examples of biennial budget ordinances and planning calendars, and a list of cities and counties that use biennial budgets.
It is part of MRSC's series on Budgeting in Washington State.
Overview
Most cities, towns, and counties in Washington operate under an annual budget, but some budget on a biennial (two-year) basis. Some special purpose districts also have the authority to budget on a biennial basis.
Advantages and Disadvantages
Commonly cited advantages of biennial budgets include:
- Reducing the total amount of time spent budgeting over a two-year period and freeing up time for other projects in year two,
- Encouraging the jurisdiction to think strategically over multiple years instead of just balancing the budget for a single year, and
- For cities in particular, de-politicizing the budget somewhat because under state law cities may only adopt biennial budgets in even-numbered (non-election) years.
Commonly cited disadvantages include:
- More time and effort required to develop the budget in year one,
- A perceived loss of control by the legislative body, since they are approving the budget for two years at a time,
- More difficulty and uncertainty forecasting revenues/expenditures further into the future, and
- Some jurisdictions spending too much time on budget amendments or the mid-biennium review and adjustment, eliminating any time savings in year two.

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 period must start on January 1 of an odd-numbered year and end on December 31 of the following even-numbered year.
Cities that budget on a biennial basis must adopt a budget no later than December 31 of the preceding even-numbered year. For detailed deadlines, procedures, and practice tips, see our pages on City and Town Budget Procedures and City and Town Budget Calendar.
In addition, the city or town must review and modify the budget sometime between September 1 and December 31 of the first (odd-numbered) year of the biennium (RCW 35.34.130/RCW 35A.34.130).
Adopting a Biennial Budget Process
Any city or town that currently budgets on an annual basis and wants to switch to a biennial budget process 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 (RCW 35A.34.040/RCW 35.34.040).
Reverting to an Annual Budget Process
Any city or town may revert to an annual budget process by repealing the ordinance that established the biennial process (RCW 35A.34.040/RCW 35.34.040). The repeal must take effect at the end of a fiscal biennium (December 31 of an even-numbered year); cities and towns may not abandon the biennial budget process halfway through the biennium. During the final (even-numbered) year of the biennium, the city or town would then prepare and adopt an annual budget to take effect January 1 of the following (odd-numbered) year.

Biennial Budgeting for Counties
Any county may adopt a biennial budget (RCW 36.40.250). Unlike cities, counties may start the biennium on January 1 of any year.
For detailed budget preparation deadlines, procedures, and practice tips, see our pages County Budget Procedures and County Budget Calendar. In addition, each county adopting a biennial budget must provide for a mid-biennial budget review and modification for the second year of the budget cycle. The modification must be adopted by resolution or ordinance. No exact deadline is provided, but in practice the budget should be reviewed and modified by the end of the first year of the biennial budget cycle.
The statute also provides an option for counties to adopt a biennial budget for some funds – with the same mandatory mid-biennium adjustment – and an annual budget for others.
Adopting a Biennial Budget Process
Any county that currently budgets on an annual basis and wants to switch to a biennial budget process must pass a resolution or ordinance to that effect (RCW 36.40.250). Unlike cities, the county statute gives no indication of when this ordinance or resolution must be passed. Practically speaking, it probably needs to be done no later than April 1 so that the request for budget proposals to county officials and department heads can outline the change and allow sufficient time to prepare the estimates that are due to the auditor in August.
Reverting to an Annual Budget Process
Any county may revert to an annual budget process by repealing the ordinance that established the biennial process (RCW 36.40.250). The repeal must take effect at the end of a fiscal biennium; counties may not abandon the biennial budget process halfway through the biennium. During the final year of the biennium, the county would then prepare and adopt an annual budget to take effect January 1 of the following year.

Biennial Budgeting for Special Purpose Districts
Most special purpose district statutes are silent on the issue of biennial budgets. However, in 2015 the state legislature passed legislation authorizing fire districts to adopt biennial budgets:
- Fire protection districts – RCW 52.16.030
- Regional fire protection service authorities – RCW 52.26.310
If a district’s statutes require an annual budget and are silent on biennial budgets, the district must adopt an annual budget. For instance, the following districts all have annual budget requirements with no mention of a biennial budget:
- Park and recreation districts – RCW 36.69.160
- Park and recreation service areas – RCW 36.68.530
- Port districts – Ch. 53.35 RCW
- Public hospital districts – RCW 70.44.060(6)
However, if the district has no specific budgetary requirements in statute – such as a water-sewer district – it may adopt budget policies as a fiscal management tool (which would be considered a best practice) that could include a biennial budget process.
Examples of Special Purpose District Biennial Budgets
- Alderwood Water and Wastewater District 2018-2019 Biennial Budget
- North City Water District 2019-2020 Biennial Budget
- Valley Communications Center 2019-2020 Biennial Budget
