Use tax is a tax imposed on the use of personal or medical goods in Washington when the goods were acquired without paying sales tax. It is computed at the same rate as the sales tax. Unless specifically exempt by law, all personal goods purchased or used in this state are subject to either the sales tax or use tax, but not both, regardless of where or from whom the property is purchased.
There are many instances where sales tax may not be collected by the seller. In those cases, including the examples listed below, the purchaser must pay use tax directly to the state.
