Wash. Rev. Code § 35.58.410
Each county that has assumed the rights, powers, functions, and obligations of a metropolitan municipal corporation under chapter 36.56 RCW shall, on or before the third Monday in June of each year, prepare an estimate of all revenues to be collected during the following calendar year, including any surplus funds remaining unexpended from the preceding year for each authorized metropolitan function.
By June 30 of each year, the county shall adopt the rate for sewage disposal that will be charged to component cities and water-sewer districts during the following budget year.
As long as any general obligation indebtedness remains outstanding that was issued by the metropolitan municipal corporation prior to the assumption by the county, the county shall continue to impose the taxes authorized by RCW 82.14.045 and * 35.58.273(4) at the maximum rates and on all of the taxable events authorized by law. If, despite the continued imposition of those taxes, the estimate of revenues made on or before the third Monday in June shows that estimated revenues will be insufficient to make all debt service payments falling due in the following calendar year on all general obligation indebtedness issued by the metropolitan municipal corporation prior to the assumption by the county of the rights, powers, functions, and obligations of the metropolitan municipal corporation, the remaining amount required to make the debt service payments shall be designated as "supplemental income" and shall be obtained from component cities and component counties as provided under RCW 35.58.420.
The county shall prepare and adopt a budget each year in accordance with applicable general law or county charter. If supplemental income has been designated under this subsection, the supplemental income shall be reflected in the budget that is adopted. If during the budget year the actual tax revenues from the taxes imposed under the authority of RCW 82.14.045 and * 35.58.273(4) exceed the estimates upon which the supplemental income was based, the difference shall be refunded to the component cities and component counties in proportion to their payments promptly after the end of the budget year. A county that has assumed the rights, powers, functions, and obligations of a metropolitan municipal corporation under chapter 36.56 RCW shall not be required to confine capital or betterment expenditures for authorized metropolitan functions from bond proceeds or emergency expenditures to items provided in the budget.
