The term "employment" includes service performed in the employ of an Indian tribe, as defined in section 3306(u) of the federal unemployment tax act, provided such service is excluded from "employment" as defined in the federal unemployment tax act solely by reason of section 3306(c)(7), the federal unemployment tax act, and is not otherwise excluded from "employment" under this title. For purposes of this section, the exclusions from employment in RCW 50.44.040, except *RCW 50.44.040(12) addressing nongovernmental preschools, are applicable to services performed in the employ of an Indian tribe.

*Reviser's note: RCW 50.44.040 was amended by 2007 c 386 § 1, changing subsection (12) to subsection (9).
