Washington State has no state income tax; taxes are primarily collected through sales tax. Western Washington is known for rain, but the state's annual rainfall is actually less than New York and Florida. This is due in part to the fact that the overcast days typical of Western Washington tend to have "drizzle" rather than downpours, and in contrast to the western part of the state, Eastern Washington has a dry desert climate due to the rain shadow effect of the Cascade mountain range.
