Each taxing authority such as the state of Washington, cities, and regional authorities such as the Regional Transit Authority can add to the sales tax charged. The total tax is collected and then distributed to each of the taxing authorities.
Example to show how the taxes collected in Seattle are distributed:
The List of Local Sales & Use Tax Rates & Changes lists all the rates within the state of Washington. It is arranged by county, so for the Seattle example, go to King County and then find Seattle. Seattle is location code 1726. The 10.25% sales tax rate in Seattle is collected and then distributed as follows: 6.5% goes to the state of Washington, 2.35% will go to the City of Seattle and King County, and 1.4% will go to the Regional Transit Authority. These 3 rates add up to the 10.25% total rate.
Important note: The tax rate used in this example is subject to change.
