2018 Budget Calendar for Counties

This calendar shows the Washington State statutory deadlines in calendar year 2017 for preparing a 2018 county budget.

Annual Budget Deadlines

The annual budget deadlines and requirements for counties are found in chapter 36.40 RCW and outlined below. For a detailed explanation of the budget requirements, as well as some helpful practice tips, see our page on Budget Preparation Procedures for Counties.

Note: These are statutory deadlines only, and the board of commissioners may set alternative dates for the budget process to conform to the alternative preliminary budget hearing date in December (RCW 36.40.071).

Many counties have adopted alternative dates, and we recommend that each county develop a timeline that best meets its needs, assures compliance with the statutes, and provides sufficient time to prepare this vital financial plan.

Biennial Budget Deadlines

Counties that have adopted a biennial (two-year) budget have the same statutory requirements and deadlines (RCW 36.40.250) as those required in the annual adoption process, plus the addition of a budget review and adjustment midway through the biennium. Counties, unlike cities, may adopt a biennial budget at the beginning of any calendar year (January 1).
