     (b) The city legislative authority determines by resolution or ordinance that the projected cost to provide municipal services to the annexation area exceeds the projected general revenue that the city would otherwise receive from the annexation area on an annual basis.
     (2) The tax authorized under this section is a credit against the state tax under chapter 82.08 or 82.12 RCW. The department of revenue ((shall)) must perform the collection of such taxes on behalf of the city at no cost to the city and ((shall)) must remit the tax to the city as provided in RCW 82.14.060.
     (3)(a) Except as provided in (b) of this subsection, the maximum rate of tax any city may impose under this section is:
     (i) 0.1 percent for each annexed area in which the population is greater than ten thousand and less than twenty thousand. The ten thousand population threshold in this subsection (3)(a)(i) is four thousand for a city with a population between one hundred fifteen thousand and one hundred forty thousand and located within a county with a population over one million five hundred thousand; and
     (ii) 0.2 percent for an annexed area in which the population is greater than twenty thousand.
     (b) Beginning July 1, 2011, the maximum rate of tax imposed under this section is 0.85 percent for an annexed area in which the population is greater than ((eighteen)) sixteen thousand if the annexed area was, prior to November 1, 2008, officially designated as a potential annexation area by more than one city, one of which has a population greater than four hundred thousand.

     (c) The threshold amount for the first fiscal year following the annexation and passage of the ordinance.

     (10) The tax ((shall)) must cease to be distributed to a city imposing the tax under subsection (3)(b) of this section for the remainder of the fiscal year, if the total distributions to the city imposing the tax exceed five million dollars for the fiscal year.
